我已经为表单字段创建了一个动态 templateUrl,我正在尝试将 ng-model 附加到 ng-repeat 中。父指令和表单字段指令都可以工作并生成,但是当我使用 ng-model 时它似乎不起作用,预输出永远不会改变?在这个用例中应用 ng-model 有技巧吗?如果我只是对表单输入使用硬编码,它就可以工作。我一直在关注 AngularJS 文档中的示例。
表单域周围的标记:
<form role="form" ng-controller="FormController as formCtrl" novalidate>
<div ng-repeat="field in panel.form_fields">
<form-field field="field"></form-field>
</div>
<fieldset class="form-group clearfix">
<button type="submit" class="btn btn-primary pull-right">Save Progress</button>
</fieldset>
<pre>form = {{models | json}}</pre>
<pre>master = {{master | json}}</pre>
</form>
表单字段指令:
angular.module('formField.directives', [])
.directive('formField', [ '$http', '$compile', function( $http, $compile ) {
var getTemplateUrl = function( field ) {
var type = field.field_type;
var templateUrl = '';
switch( type ) {
case 'textfield':
templateUrl = 'components/form-field/fields/textfield.html';
break;
case 'email':
templateUrl = 'components/form-field/fields/email.html';
break;
case 'currency':
templateUrl = 'components/form-field/fields/currency.html';
break;
case 'date':
templateUrl = 'components/form-field/fields/date.html';
break;
case 'dropdown':
templateUrl = 'components/form-field/fields/dropdown.html';
break;
case 'textarea':
templateUrl = 'components/form-field/fields/textarea.html';
break;
case 'hidden':
templateUrl = 'components/form-field/fields/hidden.html';
break;
case 'password':
templateUrl = 'components/form-field/fields/password.html';
break;
case 'checkbox':
templateUrl = 'components/form-field/fields/checkbox.html';
break;
case 'radio':
templateUrl = 'components/form-field/fields/radio.html';
break;
}
return templateUrl;
}
var linker = function( scope, element ) {
var templateUrl = getTemplateUrl( scope.field );
$http.get( templateUrl ).success(function( data ) {
element.html(data);
$compile(element.contents())(scope);
});
}
return {
restrict: 'E',
replace: true,
scope: {
field: '='
},
link: linker
}
}]);
使用的表单域模板:
<fieldset class="form-group">
<label for="{{field.field_name}}">{{field.field_label}}</label>
<input type="text"
class="form-control"
id="{{field.field_id}}"
name="{{field.field_name}}"
value="{{field.field_value}}"
placeholder="{{field.field_prompt}}"
ng-required="field.field_required"
ng-disabled="field.field_disabled"
ng-model="models[field.field_name]"> // model.test also doesn't work, and need to be able to reference the model dynamically
</fieldset>
AngularJS 文档中示例中使用的控制器:
.controller('FormController', ['$scope', function( $scope ) {
$scope.master = {};
$scope.models = {};
$scope.update = function( models ) {
console.info('Update');
$scope.master = angular.copy( models );
};
$scope.submit = function() {
console.info('Form Submitted');
};
$scope.cancel = function() {
console.info('Form Cancelled');
};
$scope.clear = function() {
console.info('Form Clear');
$scope.models = {};
}
$scope.reset = function() {
console.info('Form Reset');
$scope.models = angular.copy( $scope.master );
};
$scope.reset();
}]);
