Time slot translation in English-Slovenian dictionary. En However such a possibility must be clearly stated and a minimum objective criterion must be provided for the prior allocation of time slots depending upon the number (one, two or more than two) of carriers accepting the PSOs in order to avoid detrimental overcapacity of supply and, above all, that the allocation of time slots does not. Time Management refers to managing time effectively so that the right time is allocated to the right activity. Effective time management allows individuals to assign specific time slots to activities as per their importance. Synonyms of slot a situation or activity for which a person or thing is best suited called an old friend to see if he could find a slot for his college-age son in the construction business that summer.
This page assumes you’ve already read the Components Basics. Read that first if you are new to components.
In 2.6.0, we introduced a new unified syntax (the v-slot directive) for named and scoped slots. It replaces the slot and slot-scope attributes, which are now deprecated, but have not been removed and are still documented here. The rationale for introducing the new syntax is described in this RFC.
Slot Content
Vue implements a content distribution API inspired by the Web Components spec draft, using the <slot> element to serve as distribution outlets for content.
This allows you to compose components like this:
Then in the template for <navigation-link>, you might have:
When the component renders, <slot></slot> will be replaced by “Your Profile”. Slots can contain any template code, including HTML:
Or even other components:
If <navigation-link>‘s template did not contain a <slot> element, any content provided between its opening and closing tag would be discarded.
Compilation Scope
When you want to use data inside a slot, such as in:
That slot has access to the same instance properties (i.e. the same “scope”) as the rest of the template. The slot does not have access to <navigation-link>‘s scope. For example, trying to access url would not work:
As a rule, remember that:
Everything in the parent template is compiled in parent scope; everything in the child template is compiled in the child scope.
Fallback Content
There are cases when it’s useful to specify fallback (i.e. default) content for a slot, to be rendered only when no content is provided. For example, in a <submit-button> component:
We might want the text “Submit” to be rendered inside the <button> most of the time. To make “Submit” the fallback content, we can place it in between the <slot> tags:
Now when we use <submit-button> in a parent component, providing no content for the slot:
will render the fallback content, “Submit”:
But if we provide content:
Then the provided content will be rendered instead:
Named Slots
Updated in 2.6.0+. See here for the deprecated syntax using the slot attribute.
There are times when it’s useful to have multiple slots. For example, in a <base-layout> component with the following template:
For these cases, the <slot> element has a special attribute, name, which can be used to define additional slots:
A <slot> outlet without name implicitly has the name “default”.
To provide content to named slots, we can use the v-slot directive on a <template>, providing the name of the slot as v-slot‘s argument:
Now everything inside the <template> elements will be passed to the corresponding slots. Any content not wrapped in a <template> using v-slot is assumed to be for the default slot.
However, you can still wrap default slot content in a <template> if you wish to be explicit:
Either way, the rendered HTML will be:
Note that v-slot can only be added to a <template> (with one exception), unlike the deprecated slot attribute.
Scoped Slots
Updated in 2.6.0+. See here for the deprecated syntax using the slot-scope attribute.
Sometimes, it’s useful for slot content to have access to data only available in the child component. For example, imagine a <current-user> component with the following template:
We might want to replace this fallback content to display the user’s first name, instead of last, like this:
That won’t work, however, because only the <current-user> component has access to the user and the content we’re providing is rendered in the parent.
To make user available to the slot content in the parent, we can bind user as an attribute to the <slot> element:
Attributes bound to a <slot> element are called slot props. Now, in the parent scope, we can use v-slot with a value to define a name for the slot props we’ve been provided:
In this example, we’ve chosen to name the object containing all our slot props slotProps, but you can use any name you like.
Abbreviated Syntax for Lone Default Slots
In cases like above, when only the default slot is provided content, the component’s tags can be used as the slot’s template. This allows us to use v-slot directly on the component:
This can be shortened even further. Just as non-specified content is assumed to be for the default slot, v-slot without an argument is assumed to refer to the default slot:
Note that the abbreviated syntax for default slot cannot be mixed with named slots, as it would lead to scope ambiguity:
Whenever there are multiple slots, use the full <template> based syntax for all slots:
Destructuring Slot Props
Internally, scoped slots work by wrapping your slot content in a function passed a single argument:
That means the value of v-slot can actually accept any valid JavaScript expression that can appear in the argument position of a function definition. So in supported environments (single-file components or modern browsers), you can also use ES2015 destructuring to pull out specific slot props, like so:
This can make the template much cleaner, especially when the slot provides many props. It also opens other possibilities, such as renaming props, e.g. user to person:
You can even define fallbacks, to be used in case a slot prop is undefined:
Dynamic Slot Names
New in 2.6.0+
Dynamic directive arguments also work on v-slot, allowing the definition of dynamic slot names:
Named Slots Shorthand
New in 2.6.0+
Similar to v-on and v-bind, v-slot also has a shorthand, replacing everything before the argument (v-slot:) with the special symbol #. For example, v-slot:header can be rewritten as #header:
However, just as with other directives, the shorthand is only available when an argument is provided. That means the following syntax is invalid:
Instead, you must always specify the name of the slot if you wish to use the shorthand:
Other Examples
Slot props allow us to turn slots into reusable templates that can render different content based on input props. This is most useful when you are designing a reusable component that encapsulates data logic while allowing the consuming parent component to customize part of its layout.
For example, we are implementing a <todo-list> component that contains the layout and filtering logic for a list:
Instead of hard-coding the content for each todo, we can let the parent component take control by making every todo a slot, then binding todo as a slot prop:
Now when we use the <todo-list> component, we can optionally define an alternative <template> for todo items, but with access to data from the child:
However, even this barely scratches the surface of what scoped slots are capable of. For real-life, powerful examples of scoped slot usage, we recommend browsing libraries such as Vue Virtual Scroller, Vue Promised, and Portal Vue.
Deprecated Syntax
The v-slot directive was introduced in Vue 2.6.0, offering an improved, alternative API to the still-supported slot and slot-scope attributes. The full rationale for introducing v-slot is described in this RFC. The slot and slot-scope attributes will continue to be supported in all future 2.x releases, but are officially deprecated and will eventually be removed in Vue 3.
Named Slots with the slot Attribute
Deprecated in 2.6.0+. See here for the new, recommended syntax.
To pass content to named slots from the parent, use the special slot attribute on <template> (using the <base-layout> component described here as example):
Or, the slot attribute can also be used directly on a normal element:
There can still be one unnamed slot, which is the default slot that serves as a catch-all for any unmatched content. In both examples above, the rendered HTML would be:
Scoped Slots with the slot-scope Attribute
Deprecated in 2.6.0+. See here for the new, recommended syntax.
To receive props passed to a slot, the parent component can use <template> with the slot-scope attribute (using the <slot-example> described here as example):
Here, slot-scope declares the received props object as the slotProps variable, and makes it available inside the <template> scope. You can name slotProps anything you like similar to naming function arguments in JavaScript.
Here slot='default' can be omitted as it is implied:
The slot-scope attribute can also be used directly on a non-<template> element (including components):
The value of slot-scope can accept any valid JavaScript expression that can appear in the argument position of a function definition. This means in supported environments (single-file components or modern browsers) you can also use ES2015 destructuring in the expression, like so:
Using the <todo-list> described here as an example, here’s the equivalent usage using slot-scope:
It is rightly said “Time and Tide wait for none”. An individual should understand the value of time for him to succeed in all aspects of life. People who waste time are the ones who fail to create an identity of their own.
What is Time Management ?
- Time Management refers to managing time effectively so that the right time is allocated to the right activity.
- Effective time management allows individuals to assign specific time slots to activities as per their importance.
- Time Management refers to making the best use of time as time is always limited.
Ask yourself which activity is more important and how much time should be allocated to the same? Know which work should be done earlier and which can be done a little later.
Time Management plays a very important role not only in organizations but also in our personal lives.
Time Management includes:
- Effective Planning
- Setting goals and objectives
- Setting deadlines
- Delegation of responsibilities
- Prioritizing activities as per their importance
- Spending the right time on the right activity
Effective Planning
Plan your day well in advance. Prepare a To Do List or a “TASK PLAN”. Jot down the important activities that need to be done in a single day against the time that should be allocated to each activity. High Priority work should come on top followed by those which do not need much of your importance at the moment. Complete pending tasks one by one. Do not begin fresh work unless you have finished your previous task. Tick the ones you have already completed. Ensure you finish the tasks within the stipulated time frame.
Setting Goals and Objectives
Working without goals and targets in an organization would be similar to a situation where the captain of the ship loses his way in the sea. Yes, you would be lost. Set targets for yourself and make sure they are realistic ones and achievable.
Setting Deadlines
Set deadlines for yourself and strive hard to complete tasks ahead of the deadlines. Do not wait for your superiors to ask you everytime. Learn to take ownership of work. One person who can best set the deadlines is you yourself. Ask yourself how much time needs to be devoted to a particular task and for how many days. Use a planner to mark the important dates against the set deadlines.
Delegation of Responsibilities
Learn to say “NO” at workplace. Don’t do everything on your own. There are other people as well. One should not accept something which he knows is difficult for him. The roles and responsibilities must be delegated as per interest and specialization of employees for them to finish tasks within deadlines. A person who does not have knowledge about something needs more time than someone who knows the work well.
Prioritizing Tasks
Prioritize the tasks as per their importance and urgency. Know the difference between important and urgent work. Identify which tasks should be done within a day, which all should be done within a month and so on. Tasks which are most important should be done earlier.
Spending the right time on right activity
Develop the habit of doing the right thing at the right time. Work done at the wrong time is not of much use. Don’t waste a complete day on something which can be done in an hour or so. Also keep some time separate for your personal calls or checking updates on Facebook or Twitter. After all human being is not a machine.
For Effective Time Management one needs to be:
Organized - Avoid keeping stacks of file and heaps of paper at your workstation. Throw what all you don’t need. Put important documents in folders. Keep the files in their respective drawers with labels on top of each file. It saves time which goes on unnecessary searching.
Don’t misuse time - Do not kill time by loitering or gossiping around. Concentrate on your work and finish assignments on time. Remember your organization is not paying you for playing games on computer or peeping into other’s cubicles. First complete your work and then do whatever you feel like doing. Don’t wait till the last moment.
Be Focussed - One needs to be focused for effective time management.
Develop the habit of using planners, organizers, table top calendars for better time management. Set reminders on phones or your personal computers.
