本文實例總結了經典且實用的jQuery代碼開發技巧。分享給大家供大家參考。具體如下：
23. jQuery延時加載功能
Want to delay something?
$(document).ready(function() { window.setTimeout(function() { // do something }, 1000);});24. 移除單詞功能
Want to remove a certain word(s)?
$(document).ready(function() { var el = $('#id'); el.html(el.html().replace(/word/ig, ""));});25. 驗證元素是否存在于jquery對象集合中
Simply test with the .length property if the element exists.
$(document).ready(function() { if ($('#id').length) { // do something }});26. 使整個DIV可點擊
Want to make the complete div clickable?
$(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>});27. ID與Class之間轉換
當改變Window大小時，在ID與Class之間切換
$(document).ready(function() { function checkWindowSize() { if ( $(window).width() > 1200 ) { $('body').addClass('large'); } else { $('body').removeClass('large'); } }$(window).resize(checkWindowSize);});28. 克隆對象
Clone a div or an other element.
$(document).ready(function() { var cloned = $('#id').clone();// how to use<DIV id=id></DIV>});29. 使元素居屏幕中間位置
Center an element in the center of your screen.
$(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();});30. 寫自己的選擇器
Write your own selectors.
$(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'); });});31. 統計元素個數
Count an element.
$(document).ready(function() { $("p").size();});32. 使用自己的Bullets
Want to use your own bullets instead of using the standard or images bullets?
$(document).ready(function() { $("ul").addClass("Replaced"); $("ul > li").prepend("‒ "); // how to use ul.Replaced { list-style : none; }});33. 引用Google主機上的Jquery類庫
Let Google host the jQuery script for you. This can be done in 2 ways.
//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 type=text/javascript src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></SCRIPT> // Example 2:(the best and fastest way)<SCRIPT type=text/javascript src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></SCRIPT>34. 禁用Jquery（動畫）效果
Disable all jQuery effects
$(document).ready(function() { jQuery.fx.off = true;});35. 與其他Javascript類庫沖突解決方案
To avoid conflict other libraries on your website, you can use this jQuery Method, and assign a different variable name instead of the dollar sign.
$(document).ready(function() { var $jq = jQuery.noConflict(); $jq('#id').show();});以上就是所有關于jQuery實用技巧的全部內容，希望對大家的學習有所幫助。
