jquery.form.js异步提交表单详解

本文实例为大家分享了jquery.form.js异步提交表单的具体代码，供大家参考，具体内容如下

引入脚本:

<script type="text/javascript" src="/js/jquery.form.min.js"></script>
<script src="/js/json2.js"></script>

//前端代码:
<form id="f1">
<span class="btn-upload form-group">
<input class="input-text upload-url radius" type="text" name="uploadfile-1" id="uploadfile-1" readonly><a href="javascript:void();" rel="external nofollow" class="btn btn-primary radius"><i class="iconfont">󰀠</i> 浏览文件</a>
<input type="file" multiple name="file-1" class="input-file">
</span>
<input type="button" class="btn btn-warning radius mt-10 f-l mr-10" onclick="ImportData(this)" value="保存"/>
<a href="/files/企业表.xls" rel="external nofollow" target="_blank" class="f-16 l-30 mt-10 f-l c-danger">下载范例</a>
<div class="clearfix"></div>
</form>
//提交表单
$("#f1").ajaxSubmit({
url: "/ImportAndCheck/ImportCompanyOperation/",
type: "post",
enctype: "multipart/form-data",
dataType: "html",
beforeSubmit: function () {
$(obj).val("保存中...").attr("disabled", true);
},
success: function (response) {
try {
data = JSON.parse(response);
if (data.code > 0) {
layer.msg(data.msg, { time: 1000 });
setTimeout(function () {
window.location.href = "/ImportAndCheck/ImportCompany?status=0";
}, 1000);
} else {
layer.msg(data.msg, { time: 1000 });
$(obj).val("保存").attr("disabled", false);
}
} catch (err) {
layer.msg("导入失败！", { time: 1000 });
$(obj).val("保存").attr("disabled", false);
}
},
error: function (XmlHttpRequest, textStatus, errorThrown) {
layer.msg("导入失败", { time: 1000 });
$(obj).val("保存").attr("disabled", false);
}
});

//服务端
HttpFileCollection files = System.Web.HttpContext.Current.Request.Files;
ReturnJsonCode jsonCode = new ReturnJsonCode();
if (files == null || files.Count == 0)
{
jsonCode.msg = "请选择上传的导入文件";
return jsonCode;
}
//验证文件类型
if (files != null && files.Count > 0)
{
HttpPostedFile file = null;
file = files[0];
//扩展名检查
string picext = System.IO.Path.GetExtension(file.FileName).ToLower();
if (picext != ".xls")
{
jsonCode.msg = "上传文件仅支持xls文档格式";
return jsonCode;
}
DataTable db = ExcelToDataTable(file, file.FileName, 0);
int failcount = 0;
