核心代码:
代码如下:
script type="text/javascript"
$('#one').css("background","#fff");
$('div').css("background","#fff");
$('body div').css("background","#bbffaa");//改变body内所有div的属性
$('div span').css("background","#bbffaa").css("color","red").css("font-size","12px");//改变所有div下的span元素的属性
$('#two .mini').css("background","red");//id为two的div内的所有class为mini的元素的属性
$('#two').siblings("div").css("color","green");//选取#two同辈的div元素,无论前后位置
$('div:first').css("background","red");
$('div:gt(1)').css("background","#fff");//索引值大于1的所有div元素
$('div:lt(1)').css("background","yellow");
$('div:not(.one)').css("color","#cccccc");//改变class不为one的div元素
$('div:even').css("font-size","15px");//索引号为偶数的div
$('div:odd').css("font-size","12px");//索引号为奇数的div
$('div:contains(other)').css("font-size","10px");//设置含有文本other的div元素
$('div:has(.mini)').css("color","#bbffaa");//设置含有class为mini元素的div元素的背景色
$('div:parent').css("color","#ffcccc");//改变含有子元素（包括文本）的div元素的属性
$('div:hidden').show(3000);//获取隐藏的div
$('div:visible')//获取可见的div
$("div[title=test]").css("background","black");//设置title为test的div
$("div[.mini][title=test]").css("color","red");//设置class为mini title为test的div
