ng绑定html，变量名来自ng repeat，但在其他地方定义了变量

嗨，我对angular很陌生，所以我不确定这是否是一个明显的答案，但我正试图通过ng repeat将一个变量分配给ng bind html。然而，当我通过ng重复angular添加变量时，它只显示变量名，因为它认为html内容来自我的ng重复数据，而不是angular中的其他地方。

我的html:

<div class="brandInfo" ng-repeat="brand in itemPage.brandinfo" ng-click="widgetExpanded = !widgetExpanded">
    <div class="icon-wrapper">    
        <img ng-src="assets/img/icons/{{brand.icon}}"/>             
    </div>
    <p> {{brand.title}} </p>
    <div ng-slide-down="widgetExpanded" duration=".5">
        <p ng-bind-html="brand.iconClass"></p>
   </div>
</div>

我的控制器：

vm.brandinfo = [
                    {icon: "organicCotton.svg", iconClass: "organicCotton", title: "Organic Cotton"},
                    {icon: "lowImpactDye.svg", iconClass: "lowImpactDye", title: "Low Impact Dyes"},
                    {icon: "factory.svg", iconClass: "factory", title: "Regulated Factory"},
                    {icon: "carbonFootprint.svg", iconClass: "carbonFootprint", title: "Sustainable Business Practices"}
                ];
$scope.organicCotton = $sce.trustAsHtml(
            "<ul><li>Uses no pesticides or herbicides which a often toxic to humans and the environment</li> '
            <li>Conventional cotton accounts for 25% of global pesticide usage</li> '
            <li> Organic farming practices create healthy soils which make better use of water inputs and are more resilient in drought conditions</li> '
            <li> The water pollution impact of organic has been shown to be 98% less than non-organic cotton production.</li></ul>"
                );

所以基本上，我已经为所有iconClass的可能性设置了这些范围变量，即使我可以将正确的变量名（brand.iconClass）放入ng-bind-html指令中。它只评估为"organicCotton"，并没有意识到它是一个变量。

提前感谢您的帮助。如果我能进一步澄清，请告诉我！

请尝试以下操作：

vm.organicCotton = $sce.trustAsHtml(
        "<ul><li>Uses no pesticides or herbicides which a often toxic to humans and the environment</li> '
        <li>Conventional cotton accounts for 25% of global pesticide usage</li> '
        <li> Organic farming practices create healthy soils which make better use of water inputs and are more resilient in drought conditions</li> '
        <li> The water pollution impact of organic has been shown to be 98% less than non-organic cotton production.</li></ul>"
            );
vm.brandinfo = [
                {icon: "organicCotton.svg", iconClass: vm.organicCotton, title: "Organic Cotton"},
                {icon: "lowImpactDye.svg", iconClass: vm.lowImpactDye, title: "Low Impact Dyes"},
                {icon: "factory.svg", iconClass: vm.factory, title: "Regulated Factory"},
                {icon: "carbonFootprint.svg", iconClass: vm.carbonFootprint, title: "Sustainable Business Practices"}
            ];

因此，将变量添加到数组中，而不是将变量的名称作为字符串。

您可以将html定义为对象品牌的密钥，直接在品牌之外使用它，而不是使其复杂化。

vm.brandinfo = [
                {icon: "organicCotton.svg", iconClass: "organicCotton", title: "Organic Cotton"},
                {icon: "lowImpactDye.svg", iconClass: "lowImpactDye", title: "Low Impact Dyes"},
                {icon: "factory.svg", iconClass: "factory", title: "Regulated Factory"},
                {icon: "carbonFootprint.svg", iconClass: "carbonFootprint", title: "Sustainable Business Practices"}
            ];
vm.brandInfo[0].iconClass = $sce.trustAsHtml(
        "<ul><li>Uses no pesticides or herbicides which a often toxic to humans and the environment</li> '
        <li>Conventional cotton accounts for 25% of global pesticide usage</li> '
        <li> Organic farming practices create healthy soils which make better use of water inputs and are more resilient in drought conditions</li> '
        <li> The water pollution impact of organic has been shown to be 98% less than non-organic cotton production.</li></ul>"
            );

它只是一个数组元素的例子。
