项目中,模板中的菜单是jQuery控制的,在Angularjs中就运行不到了,因为菜单项是ng-repeat之后

项目中,模板中的菜单是jQuery控制的,在Angularjs中就运行不到了,因为菜单项是ng-repeat之后的。

如html


<ul id="main-menu">
 <li class="">
 <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Menu1</a>
 <ul class="sub-menu">
 <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--1</a></li>
 <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--2</a></li>
 </ul>
 </li>
 <li class="">
 <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Menu2</a>
 <ul class="sub-menu">
 <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--1</a></li>
 <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--2</a></li>
 </ul>
 </li>
</ul>

Jquery给第一级a链接绑定事件代码像:


$(function(){
 $("#main-menu li a").click(function(e){
 if ($(this).next().hasClass('sub-menu') === false) {
 return;
 }
 console.log("click");
 });
});

因为我之前看过文档说,Angularjs的Controller不处理Dom的操作,所以一直在找方法怎么处理和jQuery 一样绑定a的点击事件,在看了jQuery not working with ng-repeat results之后,原来可以将所有链接的单击事件,放在一个指令中。如果在Controller中绑定了ng-click,并操作了Dom元素,就不太规范了,使用指令会好一些。

html


<ul id="main-menu">
 <li class="">
 <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" toggle-main-menu>Menu1</a>
 <ul class="sub-menu">
 <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--1</a></li>
 <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--2</a></li>
 </ul>
 </li>
 <li class="">
 <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" toggle-main-menu>Menu2</a>
 <ul class="sub-menu">
 <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--1</a></li>
 <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--2</a></li>
 </ul>
 </li>
</ul>

javascript:


.directive("toggleMainMenu", function() {
 return {
 restrict: "A",
 link: function(scope, elem, attrs) {
 $(elem).click(function() {
 if($(this).next().hasClass('sub-menu') === false) {
 return;
 }
 console.log("click");
 });
 }
 }
});

原来指令是这样使用的。以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
