can-value

function

can.view.bindings.can-value

source

Sets up two way bindings in a template.

can-value='KEY'

Binds the element's value or checked property to the value specified by key. Example:

<input type='text' can-value='first.name'/>

Parameters

key {key}

A named value in the current scope.

Use

Add a can-value="KEY" attribute to an input or select element and the element's value will be cross-bound to an observable value specified by KEY.

Depending on the element and the element's type, can-value takes on different behaviors. If an input element has a type not listed here, the behavior is the same as the text type.

input type=text

Cross binds the input's string text value with the observable value.

input type=checkbox

Cross binds the checked property to a true or false value. An alternative true and false value can be specified by setting can-true-value and can-false-value attributes.

input type='radio'

If the radio element is checked, sets the observable specified by can-value to match the value of value attribute.

select

Cross binds the selected option value with an observable value.
