ready.chenready是什么意思思

JQuery(26)
一是ready,表示文档结构已经加载完成(不包含图片等非文字媒体文件)
二是onload,指示页面包含图片等文件在内的所有元素都加载完成。
用jQ的人很多人都是这么开始写脚本的:
$(function(){// do something});
其实这个就是jq ready()的简写,他等价于:
$(document).ready(function(){//do something})
//或者下面这个方法,jQuer的默认参数是:“document”;
$().ready(function(){//do something})
这个就是jq ready()的方法就是Dom Ready,他的作用或者意义就是:在DOM加载完成后就可以可以对DOM进行操作。
一般情况先一个页面响应加载的顺序是:域名解析-加载html-加载js和css-加载图片等其他信息。
那么Dom Ready应该在“加载js和css”和“加载图片等其他信息”之间,就可以操作Dom了。
以上还是本人新手时写的。。。感觉大家阅读,5000+的阅读量鄙人在此就加点内容吧,不让广大技术朋友白支持!!
-----鄙人现在已经不算新手了,在此给大家再深入说点内容吧。
1.window.onload方法
⑴执行时机:
在网页中所有元素(包括元素的所有关联文件)完全加载到浏览器后才执行,即JavaScript 此时可以访问网页中的所有元素。
window.onload=function(){ &$(window).load(function(){
//编写代码 等价于
&//编写代码
⑵多次使用:
JavaScript的onload事件一次只能保存对一个函数的引用,他会自动用最后面的函数覆盖前面的函数。
function one(){
alert(&one&);}function two(){
alert(&two&);}window.onload=one;window.onload=two;//运行代码后只有 two
2.$(document).ready()方法
⑴执行时机:在DOM完全就绪时就可以被调用。(这并不意味着这些元素关联的文件都已经下载完毕)
举个例子:$(document).ready()方法明知要DOM就绪就可以操作了,不需要等待所有图片下载完毕。
⑵多次使用:
function one(){
alert(&one&);}function two(){
alert(&two&);}$(document).ready(function(){
one();});$(document).ready(function(){
two();});//运行代码后//先是:one//先是:two

投稿:shichen2014
字体:[ ] 类型:转载 时间:
这篇文章主要介绍了多个$(document).ready()的执行顺序实例分析,对于加深理解$(document).ready()的加载与执行顺序有很大帮助,需要的朋友可以参考下
本文以实例形式说明了多个$(document).ready()的执行顺序问题,由实例可以看出多个$(document).ready()的执行顺序并非单纯的顺序执行,其与嵌套层级也有一定的关系。具体实例代码如下:
&script src="./jquery-1.9.0.min.js"&&/script&
&script type="text/javascript"&
$(function(){
alert('1');
$(function(){
alert('2');
$(function(){
alert('3');
TTTTTTTTTTTT
&script type="text/javascript"&
$(document).ready(function() {
alert('4');
$(function(){
alert('5');
KKKKKKKKKKKK
&script type="text/javascript"&
$(function(){
alert('6');
$(document).ready(function() {
alert('7');
运行alert显示顺序为:1,4,6,2,5,7,3
读者可以自己测试体验一下,以加深对多个$(document).ready()执行顺序的理解。
