当前主要用于调用uploadView.jsp方式进行文件上传
在需要文件上传的表单里面加入点击事件，调用commonUpload（回调，inputId，填充NameID，sizeId，用户id）;方法，传递相应的参数即可复用
//通用弹出式文件上传
//callback 文件上传后的回调函数
//inputId 当前文件上传控件的name值
//nameId 当前上传文件的表单文件名称name值
//sizeId 当前上传文件的大小name值
//userId 当前上传文件的用户name值
//这些参数需要在文件上传成功后回调，用于callback方法内
function commonUpload(callback,inputId,nameId,sizeId,userId){
$.dialog({
content: "url:supplierController.do?commonUpload",
lock : true,
title:"文件上传",
zIndex:getzIndex(),
width:700,
height: 200,
parent:windowapi,
cache:false,
ok: function(){
var iframe = this.iframe.contentWindow;
//调用uploadview.jsp的方法
iframe.uploadCallback(callback,inputId,nameId,sizeId,userId);
return true;
},
cancelVal: '关闭',
cancel: function(){
}
});
}
//通用弹出式文件上传-回调
//给当前页面的控件赋值
function commonUploadDefaultCallBack(url,name,size,userName,inputId,nameId,sizeId,userId){
//生成下载文件节点，绑定地址，通过servlet下载，防止游览器直接解析
$("#"+inputId+"_href").attr('href',"supplierController/filedownload.do?path="+url+"&fileName="+name).html('下载');
$("#"+inputId).val(url);
$("[name='"+nameId+"']").val(name);
$("[name='"+sizeId+"']").val(size);
$("[name='"+userId+"']").val(userName);
$("#"+inputId).parent().next().find(".saveMe").show();
