@name Cookbook: Form
|
|
@description
|
|
|
|
A web application's main purpose is to present and gather data. For this reason angular strives
|
|
to make both of these operations trivial. This example shows off how you can build a simple form to
|
|
allow a user to enter data.
|
|
|
|
|
|
<doc:example>
|
|
<doc:source>
|
|
<script>
|
|
function FormController() {
|
|
this.user = {
|
|
name: 'John Smith',
|
|
address:{line1: '123 Main St.', city:'Anytown', state:'AA', zip:'12345'},
|
|
contacts:[{type:'phone', value:'1(234) 555-1212'}]
|
|
};
|
|
this.state = /^\w\w$/;
|
|
this.zip = /^\d\d\d\d\d$/;
|
|
}
|
|
</script>
|
|
<div ng:controller="FormController" class="example">
|
|
|
|
<label>Name:</label><br/>
|
|
<input type="text" ng:model="user.name" required/> <br/><br/>
|
|
|
|
<label>Address:</label><br/>
|
|
<input type="text" ng:model="user.address.line1" size="33" required> <br/>
|
|
<input type="text" ng:model="user.address.city" size="12" required>,
|
|
<input type="text" ng:model="user.address.state" size="2"
|
|
ng:pattern="state" required>
|
|
<input type="text" ng:model="user.address.zip" size="5"
|
|
ng:pattern="zip" required><br/><br/>
|
|
|
|
<label>Phone:</label>
|
|
[ <a href="" ng:click="user.contacts.$add()">add</a> ]
|
|
<div ng:repeat="contact in user.contacts">
|
|
<select ng:model="contact.type">
|
|
<option>email</option>
|
|
<option>phone</option>
|
|
<option>pager</option>
|
|
<option>IM</option>
|
|
</select>
|
|
<input type="text" ng:model="contact.value" required/>
|
|
[ <a href="" ng:click="user.contacts.$remove(contact)">X</a> ]

# Things to notice
|
|
|
|
* The user data model is initialized {@link api/angular.directive.ng:controller controller} and is
|
|
available in
|
|
the {@link api/angular.scope scope} with the initial data.
|
|
* For debugging purposes we have included a debug view of the model to better understand what
|
|
is going on.
|
|
* The {@link api/angular.widget.HTML input widgets} simply refer to the model and are auto bound.
|
|
* The inputs {@link guide/dev_guide.forms validate}. (Try leaving them blank or entering non digits
|
|
in the zip field)
|
|
* In your application you can simply read from or write to the model and the form will be updated.
|
|
* By clicking the 'add' link you are adding new items into the `user.contacts` array which are then
|
|
reflected in the view.
