mvc jQuery 点击按钮实现导出Excel功能 参数长短不限

 1     var exportSubmit=function(url, obj){
 2         var form = $("<form>");   //定义一个form表单
 3         form.attr("class", "wdi-TempDownloadForm");
 4         form.appendTo(document.body);
 5         form.attr(‘style‘, ‘display:none‘);   //在form表单中添加查询参数
 6         form.attr(‘target‘, ‘‘);
 7         form.attr(‘method‘, ‘post‘);
 8         form.attr(‘action‘, url);
 9         for (var key in obj) {
10             var inputCtrl = $(‘<input>‘);
11             inputCtrl.attr(‘type‘, ‘hidden‘);
12             inputCtrl.attr(‘name‘, key);
13             inputCtrl.attr(‘value‘, obj[key]);
14             form.append(inputCtrl);
15         }
16         form.submit();
17     }

后台接收

1 public void ExcelsExport(FormCollection formInfos)
2 {
3     string data=formInfos["data"];
4 }    

实现

1 exportSubmit(url,{data:JSON.stringify(data)});
