我有一个以下问题:我有一个复杂的自定义指令,用于递归地从RESTful WS
获取有关输入字段的信息。我想使用ng-click
将此指令附加到包含当前<button>
的HTML元素。
请看一下appendDirective
函数。这是一个应该将指令附加到父元素的方法,该元素调用它。
指令如下所示:
app.directive('recursiveFields', function ($compile, $http) {
return {
scope: {
field: '=field',
model: '=model'
},
restrict: 'E',
replace: true,
controller: "httpPostController",
template: '<div ng-repeat="nestedField in field.nestedFields"><div ng-show="{{!nestedField.isEntity && !nestedField.isEnum}}">' + '<p ng-show={{nestedField.isRequired}}>{{nestedField.name}}*: </p>' + '<p ng-show={{!nestedField.isRequired}}>{{nestedField.name}}: </p>' + '<input type="text" ng-model="model[nestedField.name]" ng-change="getCreateEntityAsText()"' + 'class="form-control" placeholder="{{parseClassName(nestedField.type)}}">' + '</div>' + '<div ng-show="{{nestedField.isEnum}}">' + '<p ng-show={{nestedField.isRequired}}>{{nestedField.name}}*: </p>' + '<p ng-show={{!nestedField.isRequired}}>{{nestedField.name}}: </p>' + '<select ng-model="model[nestedField.name]" ng-change="getCreateEntityAsText()" class="form-control">' + '<option></option>' + '<option ng-repeat="enumValue in nestedField.enumValues" label={{enumValue.name}}>{{enumValue.ordinal}}</option>' + '</select>' + '</div>' +
'<div ng-show="{{nestedField.restResourceName != null}}">' + '<accordion close-others="oneAtATime">' + '<accordion-group heading={{nestedField.name}} is-open="false">' + /*'<recursive-fields model="createEntityResource" field="field"></recursive-fields>'*/
'<button type="button" ng-click="appendDirective()">I should append a "recursiveFields" directive</button>' + '</accordion-group>' + '</accordion>' + '</div>' + '</div>',
link: function (scope, element, attrs) {
console.log("1");
if (scope.field.restResourceName != null) {
$http.get(CONSTANTS.EXPLAIN_URL + "/" + scope.field.restResourceName).success(function (data, status) {
scope.field.nestedFields = [];
data.content.resource.fields.forEach(function (field) {
if (field.isEnum) {
$http.get(CONSTANTS.ENUMS_URL + scope.$root.parseClassName(field.type)).success(function (data, status) {
field.enumValues = [];
for (var index in data.content.values) {
field.enumValues.push(data.content.values[index]);
}
})
}
scope.field.nestedFields.push(field);
})
})
}
scope.appendDirective = function () {
var newDir = angular.element('<recursive-fields model="createEntityResource" field="field"></recursive-fields>');
$compile(newDir.contents())(scope);
alert("Done");
}
}
}
})
基本上,它看起来像这样:按<button>
1 后,<div>
2 的内容应该有嵌套指令,就像在<div>
3 。换句话说,该指令应附加到 1 的父级(元素 2 )。
有谁知道如何解决这个问题?每个有用的答案都受到高度赞赏和评价。
谢谢。

你可以这样做:
$scope.appendDirective = function () {
var recursiveFields = $("<recursive-fields />");
recursiveFields.attr("aParam", "aValue");
recursiveFields.insertAfter(yourButton);
$compile(recursiveFields)($scope);
}
在html中:
<button ng-click="appendDirective()">Your Button</button>
您的控制器必须注入$ compile:
myApp.controller("myController", $compile) {
}
