如何在离子3中包含jquery插件

我正在尝试在我的离子应用程序中实现jQuery FloatLabel - > https://github.com/m10l/FloatLabel.js/tree/master

我使用该插件是因为该插件也是在Web版本中实现的,所以在设计上要统一。

我在src / index.html里面加了jquery

<link href="assets/js/jquery.FloatLabel/jquery.FloatLabel.css" rel="stylesheet">
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="assets/js/jquery.FloatLabel/jquery.FloatLabel.js"></script>

我想在页面加载

上执行此脚本
$( '.js-float-label-wrapper' ).FloatLabel();

这是我的src / index.html代码

<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
  <meta charset="UTF-8">
  <title>Ionic App</title>
  <meta name="viewport" content="viewport-fit=cover, width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">

  <link href="build/main.css" rel="stylesheet">

  <link href="assets/js/jquery.FloatLabel/jquery.FloatLabel.css" rel="stylesheet">
  <script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
  <script src="assets/js/jquery.FloatLabel/jquery.FloatLabel.js"></script>

  <script type="text/javascript">
    $( '.js-float-label-wrapper' ).FloatLabel();
  </script>

</head>
<body>

  <!-- Ionic's root component and where the app will load -->
  <ion-app></ion-app>

  <!-- The polyfills js is generated during the build process -->
  <script src="build/polyfills.js"></script>

  <!-- The vendor js is generated during the build process
       It contains all of the dependencies in node_modules -->
  <script src="build/vendor.js"></script>

  <!-- The main bundle js is generated during the build process -->
  <script src="build/main.js"></script>

</body>
</html>

它适用于网络版但不适用于离子版。我如何在离子上实现它?

我希望它像这个小提琴 - &gt; https://jsfiddle.net/acrmktq3/

在index.html中链接jquery.js:

  <script src="assets/js/jquery-3.2.1.min.js"></script>

在节点中运行:

npm install jquery

并将其导入您的页面,如:

import * as $ from "jquery";

尝试在您的身体底部添加JavaScript代码,如下所示:

<body>

  <!-- Ionic's root component and where the app will load -->
  <ion-app></ion-app>

  <!-- The polyfills js is generated during the build process -->
  <script src="build/polyfills.js"></script>

  <!-- The vendor js is generated during the build process
       It contains all of the dependencies in node_modules -->
  <script src="build/vendor.js"></script>

  <!-- The main bundle js is generated during the build process -->
  <script src="build/main.js"></script>

  <script type="text/javascript">
    $( '.js-float-label-wrapper' ).FloatLabel();
  </script>
</body>

您在应用初始化之前添加了它,main.js甚至没有加载,您已经执行了代码,因此在代码底部使用它应该可以解决问题。

另外,您是否曾尝试在Ionic应用程序中使用此FloatLabel?由于页面可能未加载且代码已经执行,因此您需要更多的“Angular方式”。您可以在具有浮动标签的组件中使用它,只需使用它就可以在组件中使用JQuery:

declare var $: any; // declare this bellow your page imports to be able to use jQuery

或者您可以尝试Ionic浮动Label,因此您的项目中不需要使用JQuery和其他库,即使它不是“统一”设计

<ion-item>
  <ion-label color="primary" floating>Floating Label</ion-label>
  <!-- Use the floating attribute to have your label to float when you focus on the input -->
  <ion-input></ion-input>
</ion-item>

希望这有帮助。
