Question

我的范围内有两个函数fetch_orders和search_order。 fetch_order函数运行良好，但是当我单击搜索按钮时，search_order函数执行并显示错误，提示错误：[ngRepeat：dupes]。这两个函数从数据库中获取数据并显示在客户端。有没有更好的方法来获取和搜索订单？

<div class="order-data" ng-repeat="order in orders" >
    <div class="ordered-product-image">
        <img width="90%"  src="product_images/{{order.product_image}}">
    </div>
    <div class="product-contents">
       <h4>Product</h4>
        <h5 data-ng-bind="order.brand_title"></h5>
        <p data-ng-bind="order.product_title"></p>
        <p data-ng-bind="order.tarif_value_name"></p>
      </div>
</div>

首先，请在函数开始时初始化$ scope.orders变量：

$scope.orders = [];

也不要为其分配null值。

关于ngRepeat：dupes错误-请在此处检查：

Error: [ngRepeat:dupes] what does this mean?

附注：最好不要在$ scope上编写-尝试使用'controller as'语法。是从angularJS 1.2中引入的（如果我没记错的话）。
