html如下：
<form>
<div id="whiteListDiv" style="display: none;margin:-5px auto 10px auto;" class="form-group clearfix">
<label><font></font></label>
<input type="file" id="whiteList" name="whiteList" style="height: 24px; width: 500px;" />
<input type="button" class="btn-t1" onclick="uploadList('white');" value="上传" style="width: 120px; margin-left: 20px;">
</div>
<div class="form-group clearfix">
<label><font></font>是否有黑名单</label>
<input type="file" id="blackList" name="blackList" style="height: 24px; width: 500px;" />
<input type="button" class="btn-t1" onclick="uploadList('black');" value="上传" style="width: 120px; margin-left: 20px;">
</div>
</form>
注意id和name属性
function uploadList(type){
var fileList;
if(type == "white"){
fileList = $("#whiteList").val();
} else {
fileList = $("#blackList").val();
}
if(fileList == null || fileList == ""){
alert("请先选择文件再上传");
return;
}
var suffix = fileList.substring(fileList.lastIndexOf("."));
if(suffix != ".csv" && suffix != ".CSV"){
alert("请选择csv格式文件");
return;
}
var formData = new FormData($("form")[0]);
formData.append("idBombBannerInfo",sid);
formData.append("type",type);
$.ajax({
url : '../../accessManagerment/uploadFileList.do',type : 'POST',data : formData,// 告诉jQuery不要去处理发送的数据
processData : false,// 告诉jQuery不要去设置Content-Type请求头
contentType : false,beforeSend:function(){
//console.log("正在进行，请稍候");
},success : function(data) {
if(data.errorMsg != null && data.errorMsg != ""){
alert(data.errorMsg);
} else {
alert(data.resultMsg);
}
},error : function(responseStr) {
alert("上传名单出现异常");
}
});
}
由于是ajax发起请求，界面不用刷新
