Angular指令如何向元素添加属性?
我想知道如何使用此代码段:
//html<div ng-app="app">
<div ng-controller="AppCtrl">
<a my-dir ng-repeat="user in users">{{user.name}}</a>
</div>
</div>
//js
var app = angular.module('app', []);
app.controller("AppCtrl", function ($scope) {
$scope.users = [{name:'John',id:1},{name:'anonymous'}];
$scope.fxn = function() {
alert('It works');
};
})
app.directive("myDir", function ($compile) {
return {
link:function(scope,el){
el.attr('ng-click','fxn()');
//$compile(el)(scope); with this the script go mad
}
};
});
我知道这是关于编译阶段的,但是我不明白这一点,所以简短的解释将是非常感谢。
回答:
将另一个指令添加到同一元素的指令:
类似答案:
这是一个小矮人:http
://plnkr.co/edit/ziU8d826WF6SwQllHHQq?p=preview
app.directive("myDir", function($compile) { return {
priority:1001, // compiles first
terminal:true, // prevent lower priority directives to compile after it
compile: function(el) {
el.removeAttr('my-dir'); // necessary to avoid infinite compile loop
el.attr('ng-click', 'fxn()');
var fn = $compile(el);
return function(scope){
fn(scope);
};
}
};
});
更清洁的解决方案-完全不使用ngClick

矮人:http
://plnkr.co/edit/jY10enUVm31BwvLkDIAO?p=preview
app.directive("myDir", function($parse) { return {
compile: function(tElm,tAttrs){
var exp = $parse('fxn()');
return function (scope,elm){
elm.bind('click',function(){
exp(scope);
});
};
}
};
});
