在 Angular 完成渲染后运行 JQuery 代码

Run JQuery code after Angular is done rendering

本文关键字：运行 JQuery 代码 Angular      更新时间：2023-09-26

我对Angular JS很陌生，因此这个问题可能真的很愚蠢。在SO的几个问题中也讨论了它，但我无法从中做出任何贡献。

我试图做一件看似非常简单的事情，但一直非常困难。我正在尝试在 HTML 由 Angular 渲染后运行 JQuery 代码。

我已经尝试了 10 多个小时，但没有任何效果，请帮忙！

这是 JQuery 代码：-

$(".scrollable-quotes").slick({
    infinite: true,
    speed: 500,
    fade: true,
    cssEase: 'linear'
});

它基本上运行一个包含在我的索引.html中的滑块库。我的索引.html如下：-

<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <title>My Ang App</title>
    <script src="https://code.jquery.com/jquery-1.10.2.min.js"></script>
    <script src="scripts/slick/slick.min.js"></script>
  </head>
  <body ng-app="EBSheadlessDrupal" onload="StartMove()">
    <ion-nav-view></ion-nav-view>
    <!-- build:js scripts/vendor.js -->
    <!-- <script src="vendor/someContribJs.js"></script> -->
    <!-- bower:js -->
    <script src="bower_components/angular/angular.js"></script>
    <script src="bower_components/angular-animate/angular-animate.js"></script>
    <script src="bower_components/angular-sanitize/angular-sanitize.js"></script>
    <script src="bower_components/angular-ui-router/release/angular-ui-router.js"></script>
    <script src="bower_components/collide/collide.js"></script>
    <script src="bower_components/ionic/release/js/ionic.js"></script>
    <script src="bower_components/ionic/release/js/ionic-angular.js"></script>
    <!-- endbower -->
    <!-- endbuild -->
    <!-- build:js scripts/scripts.js -->
      <script src="scripts/app.js"></script>
      <script src="scripts/services.js"></script>
      <script src="scripts/controllers.js"></script>
    <!-- endbuild -->
</body>
</html>

这是我的控制器.js

'use strict';
angular.module('EBSheadlessDrupal.controllers', [])

// Controller that pulls events list from our services.
.controller('EventIndexCtrl', function($scope, EventService) {
    EventService.setups().then(function(setups){
        $scope.setups = setups.data;
        //console.log($scope.setups);
    });
})

// Controller that pulls events list from our services, and binds it to an individual view for display on the detail page.
.controller('EventDetailCtrl', function($scope, $stateParams, EventService) {
    var id = $stateParams.id;
    EventService.setups().then(function(setups){
        EventService.setup(setups.data,id, function(setup){
            $scope.setup = setup;
            //console.log($scope.setup);
            });
        });
    })
    // Controller that pulls events list from our services.
.controller('WhatIndexCtrl', function($scope, WhatService) {
    WhatService.whats().then(function(whats){
        $scope.whats = whats.data;
        //console.log($scope.whats);
    });
})

// Controller that pulls events list from our services, and binds it to an individual view for display on the detail page.
.controller('WhatDetailCtrl', function($scope, $stateParams, WhatService) {
    var id = $stateParams.id;
    WhatService.whats().then(function(whats){
        angular.element(document).ready(function () {
            document.getElementById('body').addClass("asdasdasd");
        });
        WhatService.what(whats.data,id, function(what){
            $scope.what = what;
            console.log($scope.what);
            });
        });
    })
// Controller that pulls single node JSON from our services, and binds to about.
    .controller('UserCtrl', function($scope, UserService) {
    UserService.user().then(function(user){
        $scope.user = user.data;
        //console.log($scope.user);
    });
})
// Controller that pulls single node JSON from our services, and binds to about.
    .controller('NodeCtrl', function($scope, NodeService) {
    NodeService.node().then(function(node){
        $scope.node = node.data;
        //console.log($scope.node);
    }, function(err) {
        alert(err.status + ' ' + err.statusText);
    });
})
//user login
.controller('AppCtrl', function() {
});

WhatService.whats().then(function(whats)需要它.这是我在函数中尝试的，但它不起作用：-

angular.element(".scrollable-quotes").slick({
              infinite: true,
              speed: 500,
              fade: true,
              cssEase: 'linear'
});

Angular.element使用的是jqlite，这是一个轻量级而不是jQuery。 我不熟悉光滑，但你有没有尝试过像这样执行你的代码：$（".scrollable-quotes"）.slick...

基本上就像您在第一个代码块中所说的那样。如果你在包含的脚本中使用了完整的jQuery，那么应该为完整的jQuery定义$。

这需要在指令中完成，以便您确保在运行代码时元素存在。当 jQuery.js 在 angular 之前加载在页面中时.js链接函数中的element是一个 jQuery 对象

模板中的某个地方：

<div slick >Slick content</div>

命令

angular.module('myMainApp', function(){
   return {
      restrict:'A',
      link:function(scope, element, attrs){
         element.slick({
           infinite: true,
           speed: 500,
           fade: true,
           cssEase: 'linear'
        });
      }
   }    
});

如果您需要时间先在视图中呈现数据，则可以在其中注入$timeout nd Wrap 初始化代码，以便将其推送到摘要周期的末尾
