在angularJS中使用ng-style而不是style时出错

德瓦什·阿格劳瓦尔（Devesh Agrawal）

这是我显示类别的代码：

    <select ng-style="margin-left:30px;" ng-show="ShowBrand" ng-model="SelectedBrand" ng-options="x as x.name for x in Brands | orderBy:'name'" ng-class='form-control'>
        <option value="" ng-selected="selected">Select a Brand</option>
    </select>

我在操作台窗口中看到以下错误：

    Error: [$parse:syntax] http://errors.angularjs.org/1.2.16/$parse/syntax?p0=%3A&p1=is%20an%20unexpected%20token&p2=12&p3=margin-left%3A30px%3B&p4=%3A30px%3B

select ng-style="margin-left:30px;" ng-show="ShowBrand" ng-odel="SelectedBrand" ng-options="x as x.name for x in Brands | orderBy:'name'" ng-class="form-control" class="ng-pristine ng-valid">

仅当我使用ng-style时，此错误。如果即时通讯使用样式而不是ng-style，则无法在IE9上呈现。

此错误的原因是什么以及如何解决？

ngStyle需要有效的表达式符号。因此，请尝试传递对象：
