SSH导入读取导入的Excel

一.前端关键代码

<script type="text/javascript" src="<%=basePath%>/smp/js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="<%=basePath%>/smp/js/jquery-lib/jquery.form.js"></script>
<script type="text/javascript" src="<%=basePath%>/smp/js/jquery-lib/jquery.blockUI.js"></script>
<form id="thisform" method="post"  enctype="multipart/form-data"  name="thisform" action="<%=basePath%>smp/SmpProduct-doImport.action">
    <table class="TableGeneral" border="1" cellspacing="0" cellpadding="0" rules="cols">
	 <tr class="clsItem1" height="25">
		<td class="TdNoPadding" align="left" >模板下载</td>
		<td align="left" class="TdNoPadding" style="border-bottom:#cccccc solid 1px;">
			<a href="<%=basePath%>smp/pages/smpproduct/addProduct.xls" style="text-decoration: underline;">下载添加商品模板</a>
			<a href="<%=basePath%>smp/smp/SmpProduct-downLoadProductType.action" style="text-decoration: underline;">下载商品种类对照模板</a>
		</td>
	 </tr>
	 <tr class="clsItem1" height="25">
		<td class="TdNoPadding" align="left">上传填写好的模板</td>
		<td align="left" class="TdNoPadding">
		    <input type="file" name="importFile" id="importFile"/>
		</td>
	 </tr>
	 <tr class="clsItem1" height="25">
		<td class="TdNoPadding" align="center" colspan="2" >
			<input type="submit" value="上传导入文件" onclick="doImport();" class="InputButton" />
		</td>
	 </tr>
    </table>
						
	<table cellpadding="0" cellspacing="0">
		<tr id="resultTr" style="display: none;">
			<td id="resultTd" valign="top" style="text-align: left;"></td>
		</tr>
	</table>
</form>

二.js提交脚本

//关闭
function closep(){
	parent.layer.closeAll();
}
//导入文件
function doImport() {
	$('#thisform').submit(function(){
	    var fName = $("#importFile").val();
	 	var i = fName.lastIndexOf("\\");
	 	if(i!=-1)
	 	{
	 		fName = fName.substring(i+1);
	 	}
					
		if(fName=='')
		{
			alert("请选择文件（excel文件）");
			return false;
		}
		if(fName.substring(fName.length - 4, fName.length).toLowerCase() != ".xls") {
			alert("只能导入excel文件！");
			return false;
		}
		var options = {
			url : basePath+"smp/smp/SmpProduct-doImport.action?upFile="+fName,
			beforeSubmit:  showRequest,   
			success:       showResponse,
			dataType:		'json' 
			};
		$(this).ajaxSubmit(options); 
			return false;//阻止表单提交  		
		});
	}
			 
function showRequest() {   
	$.blockUI({message: '<div style="margin: 5px;"> ' +
		'<img src="'+basePath+'/smp/images/background/ajax_loader.gif"/>' +
		 '<div style="margin: 5px; font-size: 14px;">系统正在导入数据，请稍等...</div>        </div>'
	 });  
	 return true;    
} 
		    
 function showResponse(msg) {  
	$.unblockUI();
	if(msg.result == "ok") {
		var supNumSuc = msg.supNumSuc;
		var userNumSuc = msg.userNumSuc;
		var supArrayFai = msg.supArrayFai.length;

		h += '<font color="#808000" style="line-height: 24px;">未成功导入商品：</font>'+supArrayFai+' 个。';
		if(supArrayFai > 0) {
			h += '<a href="javascript:void(0);" onclick="displayOO(\'faOO\',this)">查看</a><br />';
			h += '<span style="display:none;" id="faOO">';
		$.each(msg.supArrayFai, function(i, n){
				h += '<span style="padding-left: 20px; line-height: 20px;">'+n.message+' </span><br/>';
		});
		h += '</span>'
		} else {
			h += '<br />';
		}
		$("#resultTr").show();
		$("#resultTd").html(h);
		}else if(msg.result == "errmodle") {
			$("#resultTr").show();
			$("#resultTd").html('<font color="red">上传文件格式应为Excel文件，后缀名为【xls】！</font>');
		}else if(msg.result == "fileModeErr") {
			$("#resultTr").show();
			$("#resultTd").html('<font color="red">'+msg.errInfo+'</font>');
		}else if(msg.result == "readFileErr"){
			alert("读取Excel出错!请检查所填数据格式是否合法再提交！");
		}else if(msg.result == "noProduct"){
			alert("本次无商品导入!请检查所填数据！");
		}
				
}
		    
function displayOO(id, thi) {
	$("#"+id).toggle();
	if(thi.innerHTML=="查看"){
		thi.innerHTML = "收起";
	} else {

	}
}
