Question

需要逐个上传多个文件。假设我在一个范围内选择了几个文件并将它们显示在动态生成表中。我将逐一上传，如此处http://blueimp.github.io/jQuery-File-Upload/

一旦我点击某个特定文件的开头，它就会被上传并返回（RequestDispatcher.include）到同一页面但没有先前选择的文件。但我需要保留以前请求中未上传的文件。

我在网上找到了答案，但对答案不满意。

我认为可能有用的一些方法是：

1）设置cookie

2）在发送请求之前临时存储所有文件并将这些文件检索回jsp页面。

但我是新手，我对所有答案感到困惑。请帮帮我。

//onclick funtion triggered after clicking start button

function funIndividual(obj,e){

	var $this = $(obj);
    var rowIndex = $this.closest("tr").index();
	var singleFile =$("input[name=hidfileName]").eq(rowIndex).val();
		$('#strMode').val('UploadInd');
		$('#singleFile').val(singleFile);
			$('#fileupload').attr('action','servleturl');
			$('#fileupload').submit();
		}

}

//Snippet to generate the dynamic table
$('#document').ready(function(){
	$('#multipleFiles').on('click',function(){

	    var table = document.getElementById("table");
	 	for (var i = 0; i < inp.files.length; ++i){	
	 		var fileSize = "";
