Splix Cannot Get Input Slot Information

# Basic UsageYou can use the v-model directive to create two-way data bindings on form input, textarea, and select elements. It automatically picks the correct way to update the element based on the input type. Although a bit magical, v-model is essentially syntax sugar for updating data on user input events, plus special care for some edge cases.

v-model will ignore the initial value, checked or selected attributes found on any form elements. It will always treat the current active instance data as the source of truth. You should declare the initial value on the JavaScript side, inside the data option of your component.
v-model internally uses different properties and emits different events for different input elements: Delta burnaby casino buffet menu.
text and textarea elements use value property and input event;
checkboxes and radiobuttons use checked property and change event;
select fields use value as a prop and change as an event.
Note
For languages that require an IME(opens new window) (Chinese, Japanese, Korean etc.), you'll notice that v-model doesn't get updated during IME composition. If you want to cater for these updates as well, use input event instead.

Note
If the initial value of your v-model expression does not match any of the options, the  element will render in an 'unselected' state. On iOS this will cause the user not being able to select the first item because iOS does not fire a change event in this case. It is therefore recommended to provide a disabled option with an empty value, as demonstrated in the example above.Multiple select (bound to Array):

# Value BindingsFor radio, checkbox and select options, the v-model binding values are usually static strings (or booleans for checkbox):
But sometimes we may want to bind the value to a dynamic property on the current active instance. We can use v-bind to achieve that. In addition, using v-bind allows us to bind the input value to non-string values.
# CheckboxTip
The true-value and false-value attributes don't affect the input's value attribute, because browsers don't include unchecked boxes in form submissions. To guarantee that one of two values is submitted in a form (e.g. 'yes' or 'no'), use radio inputs instead.

#.numberIf you want user input to be automatically typecast as a number, you can add the number modifier to your v-model managed inputs:
This is often useful, because even with type='number', the value of HTML input elements always returns a string. If the value cannot be parsed with parseFloat(), then the original value is returned.

HTML's built-in input types won't always meet your needs. Fortunately, Vue components allow you to build reusable inputs with completely customized behavior. These inputs even work with v-model! To learn more, read about custom inputs in the Components guide.

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 ContentVue implements a content distribution API inspired by the Web Components spec draft, using the  element to serve as distribution outlets for content.
This allows you to compose components like this:
Then in the template for , you might have:
When the component renders,  will be replaced by 'Your Profile'. Slots can contain any template code, including HTML:
Or even other components:
If ‘s template did not contain a  element, any content provided between its opening and closing tag would be discarded.
Compilation ScopeWhen 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 ‘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 ContentThere 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  component:
We might want the text 'Submit' to be rendered inside the  most of the time. To make 'Submit' the fallback content, we can place it in between the  tags:
Now when we use  in a parent component, providing no content for the slot:
Splix Cannot Get Input Slot Information Freewill render the fallback content, 'Submit':
But if we provide content:
Then the provided content will be rendered instead:
Named SlotsUpdated 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  component with the following template:
For these cases, the  element has a special attribute, name, which can be used to define additional slots:
A  outlet without name implicitly has the name 'default'. Azure web app deployment slots pricing guide.
To provide content to named slots, we can use the v-slot directive on a , providing the name of the slot as v-slot‘s argument:
Now everything inside the  elements will be passed to the corresponding slots. Any content not wrapped in a  using v-slot is assumed to be for the default slot.

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.

Fallback ContentThere 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  component:
We might want the text 'Submit' to be rendered inside the  most of the time. To make 'Submit' the fallback content, we can place it in between the  tags:
Now when we use  in a parent component, providing no content for the slot:

Then the provided content will be rendered instead:
Named SlotsUpdated 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  component with the following template:
For these cases, the  element has a special attribute, name, which can be used to define additional slots:
A  outlet without name implicitly has the name 'default'. Azure web app deployment slots pricing guide.
To provide content to named slots, we can use the v-slot directive on a , providing the name of the slot as v-slot‘s argument:
Now everything inside the  elements will be passed to the corresponding slots. Any content not wrapped in a  using v-slot is assumed to be for the default slot.
However, you can still wrap default slot content in a  if you wish to be explicit:
Either way, the rendered HTML will be: Hillsdale kingston poker table.
Note that v-slot can only be added to a  (with one exception), unlike the deprecated slot attribute.
Scoped SlotsUpdated 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  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  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  element:
Attributes bound to a  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 SlotsIn 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  based syntax for all slots:
Destructuring Slot PropsInternally, 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 NamesNew in 2.6.0+
Dynamic directive arguments also work on v-slot, allowing the definition of dynamic slot names:
Named Slots ShorthandNew 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 ExamplesSlot 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  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  component, we can optionally define an alternative  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 SyntaxThe 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.
Splix Cannot Get Input Slot Information CheckNamed Slots with the slot AttributeDeprecated 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  (using the  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 AttributeDeprecated in 2.6.0+. See here for the new, recommended syntax.
To receive props passed to a slot, the parent component can use  with the slot-scope attribute (using the  described here as example):
Here, slot-scope declares the received props object as the slotProps variable, and makes it available inside the  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- 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  described here as an example, here's the equivalent usage using slot-scope:
