我有2个指令,一个是my-form,一个是my-field。
我需要使用动态创建这两个指令的html内容的模式。
除了我无法获得输入字段的ngModelController之外,一切正常
所以我无法获得这些字段的$ dirty,$ valid属性。
例如,在提交时,我想获取名为“field1”的输入的ngModelController,但我无法得到它。
form.field1未定义。
在FormController“form1”中,没有字段,任何人都可以帮忙吗?
非常感谢
小提琴中的代码是: https://jsfiddle.net/0td5hLur/3/
主要代码也列在下面:
angular.module('myApp', [])
.controller('MyController', ['$scope', function ($scope) {
$scope.config = {
name: 'form1',
fields: [
{type: 'text', name: 'field1', model: 'obj.field1'},
{type: 'text', name: 'field2', model: 'obj.field2'}
]
};
}])
.directive('myForm', ['$compile', function($compile) {
return {
restrict: 'E',
replace: true,
scope: {
config: '='
},
compile: function(element, attrs, transclude) {
return {
pre: function (scope, iElement, iAttrs, controller) {
console.log('-------myForm');
var html = '<form name="{{config.name}}">' +
' <my-field ng-repeat="item in config.fields" config="item"></my-field>' +
' <button ng-click="submit()">submit</button>' +
'</form>';
iElement.append($compile(html)(scope));
scope.obj = {
field1: '1',
field2: '2'
};
scope.submit = function () {
var form = scope[scope.config.name];
console.log(form);
alert(form.field1);
alert(form.field1.$dirty); // error here
}
}
};
}
}
}])
.directive('myField', ['$compile', function($compile) {
return {
restrict: 'E',
replace: true,
scope: {
config: '='
},
compile: function(tElement, tAttrs, transclude) {
return {
pre: function(scope, iElement, iAttrs, controller) {
var config = scope.config;
var html = '<input type="' + config.type + '" ng-model="' + config.model + '" name="' + config.name + '" />';
iElement.after($compile(html)(scope.$parent));
iElement.remove();
}
}
}
}
}])
;
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyController">
<my-form config="config"></my-form>
</div>
答案 0 :(得分:0)
我自己试了一下,只修改了几行,但这真的不是一件容易的事
最终工作代码如下:
我想念的是以下几行:
的 iElement.after(HTML);
var element = iElement.next();
iElement.remove();
$编译(元件)(范围$父);
