jQuery延时加载功能
- $(document).ready(function() {
- window.setTimeout(function() {
- // do something
- }, 1000);
- });
移除单词功能
- $(document).ready(function() {
- var el = $('#id');
- el.html(el.html().replace(/word/ig, ""));
- });
验证元素是否存在于jQuery对象集合中
- $(document).ready(function() {
- if ($('#id').length) {
- // do something
- }
- });
使整个DIV可点击
- $(document).ready(function() {
- $("div").click(function(){
- //get the url from href attribute and launch the url
- window.location=$(this).find("a").attr("href"); return false;
- });
- // how to use
- <DIV><A href="index.html">home</A></DIV>
- });
- ID与Class之间转换当改变Window大小时,在ID与Class之间切换
- $(document).ready(function() {
- function checkWindowSize() {
- if ( $(window).width() > 1200 ) {
- $('body').addClass('large');
- }
- else {
- $('body').removeClass('large');
- }
- }
- $(window).resize(checkWindowSize);
- });
克隆对象
- $(document).ready(function() {
- var cloned = $('#id').clone();
- // how to use
- <DIV idid=id></DIV>
- });
使元素居屏幕中间位置
- $(document).ready(function() {
- jQuery.fn.center = function () {
- this.css("position","absolute");
- this.css("top", ( $(window).height() - this.height() ) / 2+$(window).scrollTop() + "px");
- this.css("left", ( $(window).width() - this.width() ) / 2+$(window).scrollLeft() + "px");
- return this;
- }
- $("#id").center();
- });
写自己的选择器
- $(document).ready(function() {
- $.extend($.expr[':'], {
- moreThen1000px: function(a) {
- return $(a).width() > 1000;
- }
- });
- $('.box:moreThen1000px').click(function() {
- // creating a simple js alert box
- alert('The element that you have clicked is over 1000 pixels wide');
- });
- });
统计元素个数
- $(document).ready(function() {
- $("p").size();
- });
使用自己的Bullets
- $(document).ready(function() {
- $("ul").addClass("Replaced");
- $("ul > li").prepend("‒ ");
- // how to use
- ul.Replaced { list-style : none; }
- });
引用Google主机上的jQuery类库
- //Example 1
- <SCRIPT src="http://www.google.com/jsapi"></SCRIPT>
- <SCRIPT type=text/javascript>
- google.load("jquery", "1.2.6");
- google.setOnLoadCallback(function() {
- // do something
- });
- </SCRIPT><SCRIPT src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js" type=text/javascript></SCRIPT>
- // Example 2:(the best and fastest way)
- <SCRIPT src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js" type=text/javascript></SCRIPT>
禁用jQuery(动画)效果
- $(document).ready(function() {
- jQuery.fx.off = true;
- });
与其他JavaScript类库冲突解决方案
- $(document).ready(function() {
- var $jq = jQuery.noConflict();
- $jq('#id').show();
- });
