想利用jsp做上传时，为了交互采用ajax上传附件，因此表单被我设计成这样
<form onsubmit="return FileUploadFunction(this)" enctype="multipart/form-data"
method="post">
<c:forEach var="wjsInfo" items="${requestScope.resumeInfo.wjs}">
<div class="layui-upload-drag upload-area">
<input type="text" style="display:none" name="wjData" value="" class="wjData"/>
<input type="text" style="display:none" name="fileName" class="fileName">
</div>
</c:forEach>
<div class="row resume-submit" style="padding-top:30px;">
<input type="submit" style="float: none" class="button btn-save-next btn-nex" value="上传附件">
</div>
</form>
<script>
function FileUploadFunction(mdata) {
if (VailForm(mdata)) {
$.ajax({
type: "post",xhrFields: {
withCredentials: true
},crossDomain: true,url: "${pageContext.request.contextpath}/resume/saveFile",data: $(mdata).serialize(),success: function (data) {
alert(data.info);
}
});
}
return false;
}
</script>
利用按钮commit出发表单提交，提交时返回false并执行ajax，模拟表单提交上传到后台
