Javascript IE 8中带有AngularJS的未知运行时错误

我已经编写了一个简单的基于AngularJS的HTML。它有一个预定义的项目数组，并提供了

添加

和

删除

按钮，用于从列表中添加或删除项目<代码>删除按钮是一个自定义指令。下面是代码示例：（

是一个自定义指令）

    <p>
        <label>Price</label> <input type="text" ng-model="price" />
    </p>
    <p>
        <button class="btn btn-success" ng-click="addItems()">Add</button>
    </p>
    <table class="table table-striped table-hover">
        <th>Item Name</th>
        <th>Item Price</th>
        <th>Action</th>
        <tr ng-repeat="item in items|filter:name|orderBy:predicate">
            <td>{{item.name}}</td>
            <td>{{item.price | currency}}</td>

该代码在Chrome和Firfox上运行良好，但当我尝试在IE 8上运行时，它在控制台中给出了

“Error:Unknown Runtime Error”

。没有其他日志。

IE 8似乎无法处理自定义指令。删除自定义指令后，代码运行正常。声明对于自定义元素指令，我们需要调用

document.createElement（'custom-element'）

您应该阅读以下内容。

    <p>
        <label>Price</label> <input type="text" ng-model="price" />
    </p>
    <p>
        <button class="btn btn-success" ng-click="addItems()">Add</button>
    </p>
    <table class="table table-striped table-hover">
        <th>Item Name</th>
        <th>Item Price</th>
        <th>Action</th>
        <tr ng-repeat="item in items|filter:name|orderBy:predicate">
            <td>{{item.name}}</td>
            <td>{{item.price | currency}}</td>
            <td><delete-button>Remove</delete-button></td>
        </tr>

    </table>

但代码的问题可能是您将指令限制为一个元素，在IE8中，您不能这样做，而是使用Attribute

    <p>
        <label>Price</label> <input type="text" ng-model="price" />
    </p>
    <p>
        <button class="btn btn-success" ng-click="addItems()">Add</button>
    </p>
    <table class="table table-striped table-hover">
        <th>Item Name</th>
        <th>Item Price</th>
        <th>Action</th>
        <tr ng-repeat="item in items|filter:name|orderBy:predicate">
            <td>{{item.name}}</td>
            <td>{{item.price | currency}}</td>
            <td><delete-button>Remove</delete-button></td>
        </tr>

    </table>

myModule.directive("deleteButton", function() {
    return {
        restrict: "A",
        transclude: true,
        template: "<button class='btn btn-warning' ng-click='removeItem(item)' ng-transclude></button>"
    };
});

myModule.directive（“deleteButton”，function（））{
返回{
限制：“A”，
是的，
模板：“”
};
});
