js ajax

获取子节点以及数组的建立

<script type="text/javascript">
$(document).ready(function(){
	$("table tr ").each(function(){
		$(this).children("td").each(function(){
		alert($(this).eq().val());	
		});
    //alert($(this).children("td:eq(0)").text());
    //alert($(this).children("td:eq(1)").text());
});
	var tdval= $("#tr1").children("td:eq(0)");
	//alert(tdval.text());
})
var mycars=new Array();
mycars[0]="一区";
mycars[1]="CH1506";
mycars[2]="桐乡市银通汽车销售服务有限公司";
var mycar1=new Array();
mycar1[0]="一区";
mycar1[1]="CH1506";
mycar1[2]="桐乡市银通汽车销售服务有限公司";
var mo=new Array();
mo[0]=mycars;
mo[1]=mycar1;
for (i=0;i<mo.length;i++){
	for (y=0;y<mo[i].length;y++){
 		document.write(mo[i][y] + "<br />");
	}
	 
}
</script>

判断浏览器：

判断语言

var browser = {
		versions : function() {
			var u = navigator.userAgent, app = navigator.appVersion;
			return {//移动终端浏览器版本信息
				trident : u.indexOf('Trident') > -1, //IE内核
				presto : u.indexOf('Presto') > -1, //opera内核
				webKit : u.indexOf('AppleWebKit') > -1, //苹果、谷歌内核
				gecko : u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐内核
				mobile : !!u.match(/AppleWebKit.*Mobile.*/),//||!!u.match(/AppleWebKit/), //是否为移动终端
				ios : !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端
				android : u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android终端或者uc浏览器
				iPhone : u.indexOf('iPhone') > -1,// || u.indexOf('Mac') > -1, //是否为iPhone或者QQHD浏览器
				iPad : u.indexOf('iPad') > -1, //是否iPad
				webApp : u.indexOf('Safari') == -1
			//是否web应该程序，没有头部与底部
			};
		}(),
		language : (navigator.browserLanguage || navigator.language)
				.toLowerCase()
	}
	if (browser.versions.mobile) {
		location.href = 'http://m${web_dealer_domain}/${cityurl}';
	}

ajax三级别联动

$(function() {
	// "大区下拉框, 经销商类型下拉框"级联事件
	$("#regional, #dealerType").each(function() {
		$(this).bind("change", function() {
			$.ajax({
				url:"${yppam:url('findDealerByRegionalID')}",
				type:"post",
				data:"regionalID=" + $("#regional").val() + "&dealerType=" + $("#dealerType").val(),
				error:function() {
					alert('服务器繁忙~~请重试');
				}, success : function(data) {   
			 		$("#dealer").empty();
			 		$("#dealer").append("<option value=''>请选择</option>");   
					$.each(JSON.parse(data),function(key,value){
						 $("#dealer").append("<option value='"+value.id+"'>"+value.dealerName+"</option>");   
			 		});
			  	}
			});
		});
	});});
