AngularJS:使用指令添加HTML [英] AngularJS: Prepend HTML using Directive

问题描述

Service.js

this.showSpinner = function (Id) {

    angular.element("<wave-spinner id='spinner00' ng-show='true'></wave-spinner>").remove();
    var myEl = angular.element(document.querySelector("#header00"))
    myEl.prepend($compile("<wave-spinner id='spinner00' ng-show='true'></wave-spinner>")($rootScope));
};

HTML

<div id="header00" style="">Some Content</div>

我尝试使用 jQlite 中提到的prepend方法，但它不起作用.

I tried using prepend method as mentioned in jQlite, but its not working.

1. 如何在div header00之前显示指令? .append与 指令，但不.prepend在匹配的div之前添加任何html内容 元素.
2. 再次调用指令时，如何删除现有的html. remove()对我不起作用.

1. How do I show directive before div header00? .append works with directive but not .prepend to add any html content before matched div element.
2. When directive is called again, how do I remove existing html. remove() is not working for me.

推荐答案

您的代码只需进行简单的更改.将不存在的之前功能切换为 prepend (您说过已经尝试过，但是我确定这是解决此问题的方法).

Your code only needs a simple change. Switch the before function which does not exist to prepend ( You said that you have tried it but I'm sure this is the solution to this problem ).

myEl.prepend($compile("<wave-spinner id='spinner00' ng-show='true'></wave-spinner>")($rootScope));
