如何获得下拉单击项目值角js

Question

我创建了一个函数名称是rate。当页面加载功能正常时。 Ajax方法正在从API获得结果。当功能完成ng-repeat工作正常时。稍后，当我单击下拉菜单项时，该功能正在运行，但我希望单击下拉菜单项值以插入{{status.value}}。我也有不同的问题。当循环工作时，浏览器冻结。我该如何解决这个问题？

HTML代码

<div class="analysisItem col-sm-6" ng-if="status">
    <div class="item">
        <div class="dropdown">
            <div class="analysisbutton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                <div class="container">
                    <div class="row">
                        <div class="a col-12">Arz<br><span class="value">{{status.value}}</span><span class="dropdown-arrow"></span></div>
                    </div>
                </div>
            </div>
            <div class="dropdown-menu w-100">
                <a class="dropdown-item" ng-repeat="i in statusRes" data-type="status" data-value="{{i.valueint}}" ng-click="rate();">{{i.value}} <span class="float-right">%{{i.factor}}</span></a>
            </div>
        </div>
    </div>
</div>

JS代码
