如何在jquery-mobile/phonegap的$(document).ready()/ onDeviceReady()上加载脚本

Question

我正在使用PhoneGap和jQuery Mobile开发应用程序.

现在当页面加载然后我想加载一个script(.js file).基本上onDeviceReady或$(document).ready().怎么做？

Answer 1

//wait for document.ready to fire
$(function () {

    //then load the JavaScript file
    $.getScript('script.js');
});

http://api.jquery.com/jquery.getscript

//create a callback function
function myCallback () {


    //create a script element and set it's type and async attributes
    var script = document.createElement('script'); script.type = 'text/javascript'; script.async = true;

    //set the source of the script element
    script.src = 'script.js';


    //add the script element to the DOM
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(script, s);

}

//add event listener for the deviceready function to run our callback function
document.addEventListener("deviceready", myCallback, false);

第二个代码段是Google Analytic代码的略微修改版本,用于异步地向DOM添加脚本.

UPDATE

您还可以将标记的defer属性设置为<script>,true并且在DOM准备好之后才会执行.请参阅此处的一些文档:https://developer.mozilla.org/en-US/docs/HTML/Element/Script
