java-導出excel並解決亂碼問題

技術 struts2+easyui（參考，主要解決編碼和excel導出問題)

表單的設置

<form id="form1" name="form1" method="post"  accept-charset="GBK" onsubmit="if(!!window.ActiveXObject){document.charset='GBK';}"  ></form>

js代碼

 //彈框式導出到Excel表中
	 function exportExcel(){
		var gs = $('#gs').combobox('getValue');
		var ssjd = $('#jd').combobox('getValue');
		var number = $("#number").val();
		var name = $("#name").val();

<%--方法一--%>
<%--		//alert("查詢條件：歸屬："+gs+",街道:"+ssjd+",編號："+number+",姓名："+name);--%>
<%--		form1.action='/mzj/zjgl/exportExcel.action?rygs='+gs+'&ssjd='+ssjd+'&rybh='+number+'&name='+name,--%>
<%--		form1.submit();--%>
<%--方二--%>
<%--		--%>
<%--		 $.ajax({  --%>
<%--			contentType : "application/json",--%>
<%--			url:'/mzj/zjgl/exportExcel.action?rygs='+gs+'&ssjd='+ssjd+'&rybh='+number+'&name='+name,--%>
<%--			type:"post",--%>
<%--			dataType:"json",--%>
<%--			async:false,--%>
<%--			success:function(data) --%>
<%--			{--%>
<%--			},--%>
<%--		 	error : function() {  --%>
<%--                alert("導出失敗");  --%>
<%--			}--%>
<%--		});--%>
<%--方三--%>		 
<%--		 jQuery("form")//選擇form    --%>
<%--		 .first()//選擇第一個 第二個用eq(1) 最後一個 last()    --%>
<%--		 .attr("action",'/mzj/zjgl/exportExcel.action?rygs='+gs+'&ssjd='+ssjd+'&rybh='+number+'&name='+name)//更改屬性    --%>
<%--		 .submit();//提交--%>
<%--同方三--%>		 
		    var url='/mzj/zjgl/exportExcel.action?rygs='+gs+'&ssjd='+ssjd+'&rybh='+number+'&name='+name; 
			$("#form1").attr("action",url); 
			$("#form1").submit(); 
		 
	 }
