<p tab-img class="I_AF_p" ng-click="goto('index')"><img ng-src="{{imgsrc.imda1}}" alt=""><span>首页</span></p>
<p tab-img class="I_AF_p" ng-click="goto('ye')"><img ng-src="{{imgsrc.imda2}}" alt=""><span>余额</span></p>
<p tab-img class="I_AF_p" ng-click="goto('js')"><img ng-src="{{imgsrc.imda3}}" alt=""><span>计算</span></p>
<p tab-img class="I_AF_p" ng-click="goto('ck')"><img ng-src="{{imgsrc.imda4}}" alt=""><span>查看</span></p>
<p tab-img class="I_AF_p" ng-click="goto('wd')"><img ng-src="{{imgsrc.imda5}}" alt=""><span>文档</span></p>
点击相应的p之后获取索引,然后更改$scope.imgsrc中相应的值,控制台能正确输出图片地址,但是视图中ng-src中的值为什么需要点击两次才能改变,我只是想更改ng-src中的图片地址,刚开始学angularjs,谁帮我解释下,谢谢。

需要手动触发angular的渲染机制
link:function (scope,ele,attr,ctrl, $timeout) {
ele.bind('click',function (event) {
var index = $(this).index();
scope.imgsrc = {
"imda1":"img/icon1.png",
"imda2":"img/icon2.png",
"imda3":"img/icon3.png",
"imda4":"img/icon4.png",
"imda5":"img/icon5.png"
};
$timeout(function() {
scope.imgsrc['imda'+(index+1)] = 'img/icon'+(index+1)+'1.png';
//scope.$apply(scope.imgsrc['imda'+(index+1)] = 'img/icon'+(index+1)+'1.png')
})
})
}
