我的问题如下:
手动创建文档时如下:
<div model="image" ctrl="Dropdown">
<div value="show">Show Images</div>
<div value="hide">Hide Images</div>
<div value="showhover">Show Images on Hover</div>
</div>
下拉列表中的div被赋予正确的类,并且在鼠标移除时它们会发生变化,但是,当使用ng-repeat时,ng-repeat创建的div不能保存动态类
<div wix-model="image" wix-ctrl="Dropdown">
<div ng-repeat="page in pages" value={{$index}}>
{{page.title}}
</div>
</div>
* model和ctrl属性是我正在使用的UI库的一部分。
有没有办法让这些div表现得像手动创建的那样? 谢谢!
编辑: 我可能不清楚,
以下HTML,
<div wix-model="image" wix-ctrl="Dropdown">
<div value="show">Show Images</div>
<div value="hide">Hide Images</div>
<div value="showhover">Show Images on Hover</div>
</div>
生成此HTML:
<div wix-model="image" wix-ctrl="Dropdown" class="dropdown dropdown-style-1 focus-active"><span class="dropdown-arrow dropdown-arrow-down"></span>
<div class="selected">
<div data-value="show" data-index="0" class="option current-item">Show Images</div>
</div>
<div class="options uilib-scrollbar" style="width: 100%; position: absolute; top: 100%; z-index: 999999; display: block; overflow: auto;">
<div data-value="show" data-index="0" class="option option-selected dropdown-highlight">Show Images</div>
<div data-value="hide" data-index="1" class="option">Hide Images</div>
<div data-value="showhover" data-index="2" class="option">Show Images on Hover</div>
</div>
</div>
有没有办法在页面加载之前将这些div推入wix-model div之下,这样当它出现时,div已经存在并将获得正确的类等? 谢谢!

虽然我建议你找出一个条件或逻辑来渲染类。但是,根据您提供的信息,此解决方案可以正常运行。
<div wix-model="image" wix-ctrl="Dropdown">
<div ng-class="{'Show Images':'show', 'Hide Images':'hide', 'Show Images on Hover':'showhover'}[page.title]" ng-repeat="page in pages" value={{$index}}>
{{page.title}}
</div>
</div>
修改强>
我根据您提供的说明使用了对象$scope.pages
。当您运行以下代码段时,您可以清楚地看到这些类的应用方式。
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script>
</head>
<body ng-controller="myCtrl">
<div wix-model="image">
<div ng-class="{'Show Images':'show', 'Hide Images':'hide', 'Show Images on Hover':'showhover'}[page.title]" ng-repeat="page in pages" value={{$index}}>
{{page.title}}
</div>
</div>
<script>
var myApp = angular.module("myApp", []);
myApp.controller("myCtrl", ['$scope', function($scope) {
$scope.pages = [
{title : 'Show Images', otherprop : 'lorem ipsum'},
{title : 'Hide Images', otherprop : 'lorem ipsum'},
{title : 'Show Images on Hover', otherprop : 'lorem ipsum'}
];
}]);
</script>
</body>
</html>
&#13;
<强>输出强>
<div wix-model="image">
<!-- ngRepeat: page in pages -->
<div ng-class="{'Show Images':'show', 'Hide Images':'hide', 'Show Images on Hover':'showhover'}[page.title]" ng-repeat="page in pages" value="0" class="ng-binding ng-scope show">
Show Images
</div>
<!-- end ngRepeat: page in pages -->
<div ng-class="{'Show Images':'show', 'Hide Images':'hide', 'Show Images on Hover':'showhover'}[page.title]" ng-repeat="page in pages" value="1" class="ng-binding ng-scope hide">
Hide Images
</div>
<!-- end ngRepeat: page in pages -->
<div ng-class="{'Show Images':'show', 'Hide Images':'hide', 'Show Images on Hover':'showhover'}[page.title]" ng-repeat="page in pages" value="2" class="ng-binding ng-scope showhover">
Show Images on Hover
</div>
<!-- end ngRepeat: page in pages -->
</div>
您可以轻松了解如何应用show
,hide
和showhover
类。

您可以使用ng-class指令来实现这一目标。 class1&amp; class2是你在css中定义的类。
<div ng-repeat="page in pages" value={{$index}} ng-class="style">
{{page.title}}
</div>
//Controller Code
$scope.style = class1;// or class2 according to your requirement
