导出excel——弹出框

表单提交

凡是表单提交（表单提交分3种，见下面的1、2、3）的话，并且设置了表单标签的enctype="multipart/form-data"属性，那么这个时候就会打开弹出框。

1.表单提交

2.js表单提交

3.jquery、extjs等等其他的表单提交

代码示例

//jsp代码
<s:form id="myform1" method="post" enctype="multipart/form-data">
		<table width="400">
			<tr>
				<td>导出</td>
				<td align="center"><input type="button" value="导出Excel表格"
					onclick="excelExpert()" />
				</td>
			</tr>
		</table>
	</s:form>
//js代码
function excelExpert() {
		var form = document.getElementById("myform1");
		form.action = "/ProjectManagerWeb/shangbaoAction!exportExcelOfSta.action";
		form.submit();
}
//java代码：业务控制器
/**
	 * 项目数据查询 导出到excel
	 */
	public void exportExcelOfSta(){

非表单提交

如果不是表单提交，那么一定是请求。只要是请求的话，不管是下面的1、2中的哪一种，都不会打开弹出框——除非用window.open(url)发出请求，或者，在回调函数里用window.open(url)打开一个窗口（前提是服务器的磁盘上url这个路径下已经生成了这个excel文件）。

1.jquery请求

2.extjs请求

代码示例1

//js代码（注：extjs）
{columnWidth: .1, layout: 'form', border: false, items:[
			    { xtype:'button',text: '导出Excel表格',handler: function(){
//			    	Ext.Ajax.request({
//			    		url :'/ProjectManagerWeb/shangbaoAction!exportExcelOfSta.action',
//			        	  method :'post',
//			        	  success :function(form,action){
//			        		  Ext.Msg.alert("提示","success");
//			        	  },
//			        	  failure :function(form,action){
//			        		  Ext.Msg.alert("提示","success");
//			        	  }
//					});
			    	window.open("/ProjectManagerWeb/shangbaoAction!exportExcelOfSta.action");
			    }}
			]}

代码示例2

//js代码（注：jquery请求）
var btnExportHtml;

function doExport(id){
	var obj=$("#div_btnExport");
	btnExportHtml=obj.html();
	obj.html("<img src='/images/icon_loading.gif' border='0'/>Exporting files, please wait...");
	$.post("export.jsp",{ordId:id},function(json){
		obj.html(btnExportHtml);
		if(json.success){
			window.open(json.uri,"","");
		}
	},"json");
	return false;
}
//java代码：业务控制器
public String export() throws Exception{
		SalesOrder var=handler.retrieve(form.getOrdId());
		String uri="/exports/order/"+var.getOrderNo()+".xls";
		String fn=application.getRealPath(uri);
		SalesOrderExporter exp=new SalesOrderExporter(fn,var,application);
		exp.export();
		json="{\"success\":true,\"uri\":\""+uri+"\"}";
		return SUCCESS;
	}
