Angular js与jquery multiselect不兼容

我有这个jQuery选择器。一切都工作正常但只是通过添加和初始化角度,多选择停止工作。您可以尝试删除所有不必要的内容,并且您会看到这种情况发生:

(我不知道为什么github的网址不在这里工作,但你可以根据需要下载文件,因为这不是我试图描述的问题)

如评论中所述,在指令中添加jQuery插件代码并删除document.ready内容,因为指令中不需要它。 当您在指令的链接方法中添加插件代码时,DOM已准备好。

我还没有对其余的角度代码进行测试,因为它看起来太复杂了,我已对其进行重新编码以提高可读性。 (也许你的代码正在运行,但我不会这样编码。)

请查看下面的演示或此jsfiddle

为了更好地理解指令,请阅读有关directives的文档以获取自定义指令的基础知识。

无论如何这里是指令的解释:

multiselect指令作为属性指令(restrict: 'A')添加到select标记中,因此link函数内部的元素是您要应用jQuery插件的select标记。 (在链接内部使用jQuery函数是安全的,但我建议将使用量减少到最小值。)

在Google中搜索link, compile, controller或在此搜索SO以了解有关指令的更多信息。在SO处有一个问题,它们之间存在差异。

您还可以使用模板创建元素指令,然后可以将select标记添加到指令中并使用双向绑定传递您的选择。这可能更好,因为它更可重复使用。

angular.module('campaignListing', [])
    .controller('CampaignListController', CampaignListController)
    .directive('multiselect', MultiSelectDirective);

function CampaignListController($http) {
    this.filters = {
        status: 'active',
        client: null
    };
    var campaigns = {};
    this.update_fields = function () {
        console.log("update!");
        console.log(this.filters);
    }
}

function MultiSelectDirective() {
    return {
        restrict: 'A',
        link: function (scope, element) {
            $(element).multiselect({
                includeSelectAllOption: true,
                enableFiltering: true,
                nonSelectedText: 'Status'
            });
        }
    }
