复制代码 代码如下:
<script type="text/javascript" src="jquery-1.8.2.min.js"></script>
<script type="text/javascript"> <br>$(document).ready(function(){ <br>//进行遍历一维数组 <br>var arr1 = [ "aaa", "bbb", "ccc" ]; //同c语言不同时变量值使用[] 而不是{} <br>$.each(arr1, function(i,val){ <br>alert(i+"前面是下标后面是值"+val); <br>}); <br><br>//遍历二维数组 <br>var arr2 = [['a', 'aa', 'aaa'], ['b', 'bb', 'bbb'], ['c', 'cc', 'ccc']]; <br> $.each(arr2, function(i, item){ <br>alert(i+"前面是下标后面是值"+item); <br> }); <br> $.each(arr2, function(i, item){ <br> $.each(item,function(j,val){ <br> alert(j+"前面是下标后面是值"+val); <br> }); <br>}); <br><br>//循环遍历dom对象 <br>$.each($("input:hidden"), function(i,val){ <br>alert(val); //为dom对象 <br>alert(i); //为下标0 1 2 <br>alert(val.name); <br>alert(val.value); <br>}); <br>//结果和上面一样 <br>$("input:hidden").each(function(i,val){ <br>alert(i); <br>alert(val); <br>alert(val.name); <br>alert(val.value); <br>}); <br><br><br>}); <br><br></script>
