我在cordova build中点击按钮重定向到另一个页面时遇到问题,错误是Uncaught ReferenceError: $ is not defined

(function () {
"use strict";
document.addEventListener( 'deviceready', onDeviceReady.bind( this ), false );
function onDeviceReady() {
// Handle the Cordova pause and resume events
document.addEventListener( 'pause', onPause.bind( this ), false );
document.addEventListener('resume', onResume.bind(this), false);
$("getas").click(function () {
alert("The paragraph was clicked.");
});

我做错了什么?我已经在 onclick 按钮“document.location.href='example.html'”中尝试过,但根本不起作用
谢谢
【问题讨论】:
-
请不要在您的 Cordova 应用程序中远程加载 JQuery JS 和 CSS 等资源 - 将它们移动到本地以说明您的脚本文件夹。如果您依赖远程样板 JS 作为框架,该应用程序将运行缓慢且无法在离线情况下运行。你是怎么到另一页的?你是远程加载吗?理想情况下,您的应用应该是单个页面,其所有页面模板都在本地构建到应用中,并且应该使用 API 从服务器获取数据,而不是依赖远程 HTML 文档。
-
我现在把这个引用放在本地,但没有解决问题,同样的错误引用到 $("getas").click(function () {** **$ 处未捕获的错误 现在它加载资源失败,错误 加载资源失败:服务器响应状态为 404(未找到)
-
这意味着您仍然没有将其指向正确的路径。仔细检查你的路径。尝试文件的相对路径和绝对路径。
-
这有帮助吗?
(function () { ... } )(jQuery);我想我以前见过这个在哪里使用这个(function () {} )();让一切都保持在本地? -
此时我有这个但也没有工作:(
