本文实例总结了经典且实用的jQuery代码开发技巧。分享给大家供大家参考。具体如下：
23. jQuery延时加载功能
Want to delay something?
rush:js;">
$(document).ready(function() {
window.setTimeout(function() {
// do something
},1000);
});
24. 移除单词功能
Want to remove a certain word(s)?
rush:js;">
$(document).ready(function() {
var el = $('#id');
el.html(el.html().replace(/word/ig,""));
});
25. 验证元素是否存在于jquery对象集合中
Simply test with the .length property if the element exists.
rush:js;">
$(document).ready(function() {
if ($('#id').length) {
// do something
}
});
26. 使整个DIV可点击
Want to make the complete div clickable?
rush:js;">
$(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
});
27. ID与Class之间转换
当改变Window大小时，在ID与Class之间切换
1200 ) {
$('body').addClass('large');
}
else {
$('body').removeClass('large');
}
}
$(window).resize(checkWindowSize);
});
28. 克隆对象
Clone a div or an other element.
rush:js;">
$(document).ready(function() {
var cloned = $('#id').clone();
// how to use
});
29. 使元素居屏幕中间位置
Center an element in the center of your screen.
rush:js;">
$(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. 写自己的选择器
Write your own selectors.
1000;
}
});
$('.
Box:moreThen1000px').click(function() {
// creating a simple js alert
Box
alert('The element that you have clicked is over 1000 pixels wide');
});
});
31. 统计元素个数
Count an element.
rush:js;">
$(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?
li").prepend("‒ ");
// how to use
ul.Replaced { list-style : none; }
});
33. 引用Google主机上的Jquery类库
Let Google host the jQuery script for you. This can be done in 2 ways.
<div class="jb51code">
<pre class="brush:js;">
//Example 1
<SCRIPT src="http://www.google.com/jsapi">
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.
rush:js;">
$(document).ready(function() {
var $jq = jQuery.noConflict();
$jq('#id').show();
});
