/etc/nginx/nginx.conf.jquery中each遍历对象和数组示例
投稿：whsnow

jquery中each可用于遍历对象和数组，如需退出each循环可使回调函数返回false，下面有个示例，大家可以看看
&通用遍历方法，可用于遍历对象和数组。$().each()，回调函数拥有两个参数：
第一个为对象的成员或数组的索引，第二个为对应变量或内容。如需退出each循环可使回调函数返回false
现有如下两个select
&select id="PLANTYPE"&
&option value="0"&-所有-&/option&
&option value="1"&新建&/option&
&option value="2"&续建&/option&
&select id="AUDITTYPE"&
&option value="0"&-所有-&/option&
&option value="1"&申报&/option&
&option value="2"&修改&/option&
使用each方法获取option中的文本值，即 -所有-、新建、续建...
如果只使用一次each循环 可从option处开始
$("option").each(function(index,data){
($( data ).text());
//或者($(this).text());
也可从select处开始
$("select").each(function( index,data){
$("option", data).each(function(m,n){
($(this).text());
$("option", data)一定要加上 data或者$("option",this)，表示此对象下的option
否则就是所有的option。
--------------------------华丽的分割线-----------------------------
each还有一种用法jQuery.each(object, [callback])
不同于jQuery对象的$().each()方法，此方法可用于例遍任何对象。
用此方法同样遍历上述代码
$.each($("option"),function(index,data){
(index+" "+data);
也可以遍历数组
$.each( [0,1,2], function(i, n){
( "Index：" + i + ": " + n );
$.each({ name: "itmyhome", addr: "Beijing" },function(i, n){
("Name: " + i + ", Value: " + n);
