NG-点击不工作的NG-如果
问题描述:
为什么第二个按钮不起作用,NG-如果在使用?
我想实现一个按钮,为present仅当模型值设置/不是/ NOT NULL。
I want to realize a button that is present only when the model value is set / not ""/ not null.
模板:
<input type="text" ng-model="blub"/>
<br/>
<button ng-click="blub = 'xxxx'">X</button>
<br/>
<button ng-click="blub = 'yyyy'" ng-if="blub.length">Y</button>
控制器:
angular.module('test', [])
.controller('Main', function ($scope) {
// nothing to do here
});
