表单提交
凡是表单提交（表单提交分3种，见以下的1、2、3）的话。而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等等其它的表单提交
代码演示样例
//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

非表单提交
假设不是表单提交。那么一定是请求。仅仅要是请求的话，无论是以下的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)打开一个窗体（前提是server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
代码演示样例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");
}}
]}代码演示样例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;
}
