jq文件上传

① jquery html5怎样把文件上传到文件夹

楼主你好！根据你的描述，让我来给你回答！

var fd = new FormData(document.getElementById("fileinfo"));

fd.append("CustomField", "This is some extra data");

$.ajax({

url: "stash.php",

type: "POST",

data: fd,

processData: false, // tell jQuery not to process the data

contentType: false // tell jQuery not to set contentType

});

希望能帮到你，如果满意，请记得采纳哦~~~

③ 如何用jq获取file的上传文件

我的理解是你应该先通过图片上传接口把图片上传到服务器上（上传后的服务器端的图片地址，保存到里），然后再统一提交所有的表单项。

④ jquery怎么上传多个文件上传

jquery有个插件叫uploadify
http://www.uploadify.com/
$(function() { $("#file_upload_1").uploadify({ height : 30, swf : '/uploadify/uploadify.swf', uploader : '/uploadify/uploadify.php', width : 120 });});

⑦ jquery的post方法上传文件问题。

用AJAXForm插件来完成，当然还有很多的jquery插件可以完成无刷新上传，甚至是多文件无刷新同时上传

⑧ jquery 知道文件路径怎么上传

我的理解是你应该先通过图片上传接口把图片上传到服务器上（上传后的服务器端的图片地址，保存到<input type="hidden">里），然后再统一提交所有的表单项。

⑨ jquery上传文件是怎么实现的

本篇文章是对Jquery中的LigerUI实现文件上传的方法，进行了分析介绍，需要的朋友可以参考下
一、在Head中加入
<script src="../lib/js/ajaxfileupload.js" type="text/javascript"></script>
<script src="../lib/js/ligerui.expand.js" type="text/javascript"></script>
二、Html中的Div代码

复制代码 代码如下:
<div id="AppendBill_Div" style="display:none;"> <%-- 上传 - 单 --%>
<table style="height:100%;width:100%">
<tr style="height:40px">
<td style="width:20%">
图标:
</td>
<td><input type="file" style="width:200px" id="fileupload" name="fileupload"/>
</td>
</tr>
</table>
</div>

三、Js中-写的是关键部分，会LigerUI的朋友-你懂得
1、grid中添加项【存地址字段】
{ display: "扫描件", name: "AppendBillPath", width: 120, type: "text", align: "left" }
2、Form可添加项【存地址和弹出选择框】
{ name: "AppendBillPath1", type: "hidden" }, // --上传-【5】--
{ display: "扫描件", name: "AppendBillPath", comboboxName: "AppendBillPath2", newline: true, labelWidth: 100, width: 150, space: 30, type: "select", options: {}} // --上传-【6】--
$.ligerui.get("AppendBillPath2").set('onBeforeOpen', f_selectAppendBillPath_1) // 【扫描件】 // --上传-【7】--
3、事件
// #region ======================================= 【上传扫描件窗口】 // --上传-【8】--
复制代码 代码如下:
var AppendBillPathDetail = null;
function f_selectAppendBillPath_1() {
var imageurl = $("#AppendBill").val();
var AppendBill_Id = $("#AppendBill").val(); // 单号
if (imageurl.length == 0) {
LG.showError("您没有输入单号，请输入随单号！");
return;
}
if (AppendBillPathDetail) {
AppendBillPathDetail.show();
}
else {
AppendBillPathDetail = $.ligerDialog.open({
target: $("#AppendBill_Div"), title: '添加图标',
width: 360, height: 170, top: 170, left: 280, // 弹出窗口大小
buttons: [
{ text: '上传', onclick: function () { AppendBillPath_save(); } },
{ text: '取消', onclick: function () { AppendBillPathDetail.hide(); } }
]
});
}
}
function AppendBillPath_save()
{
var imgurl = $("#fileupload").val();
// var filehelpcode = $("#filehelpcode").val();
var extend = imgurl.substring(imgurl.lastIndexOf("."), imgurl.length);
extend = extend.toLowerCase();
if (extend == ".jpg" || extend == ".jpeg" || extend == ".png" || extend == ".gif" || extend == ".bmp")
{
}
else
{
LG.showError("请上传jpg,jpep,png,gif,bmp格式的图片文件");
return;
}
var imageurl = $("#AppendBill").val(); // extend
alert(imageurl);
$.ajaxFileUpload({
url: "../handle/ImageUpload.aspx?imageurl=" + imageurl, // --上传-【9】-- aspx文件
secureuri: false,
fileElementId: "fileupload", //Input file id
dataType: "text",
success: function (data, status)
{
// ----------------- // 保存路径
// $("#AppendBillPath2").val(Data);

LG.tip(data);
f_reload();
},
error: function (data, status, e) {
LG.showError(data);
}
});
}
// #endregion

四、后台cs，写一句关键的，可以返回参数，前台提示
string url = Server.MapPath("/Image/" + gfilename + filenameext); // 执行上传操作

⑩ 怎么样通过jQuery Ajax实现上传文件

Query Ajax在web应用开发中很常用，它主要包括有ajax,get,post,load,getscript等等这几种常用无刷新操作方法，接下来通过本文给大家介绍jquery ajax 上传文件处理方式。
FormData对象
XMLHttpRequest Level 2添加了一个新的接口FormData.利用FormData对象,我们可以通过JavaScript用一些键值对来模拟一系列表单控件,我们还可以使用XMLHttpRequest的send()方法来异步的提交这个”表单”.比起普通的ajax,使用FormData的最大优点就是我们可以异步上传一个二进制文件.
所有主流浏览器的较新版本都已经支持这个对象了，比如Chrome 7+、Firefox 4+、IE 10+、Opera 12+、Safari 5+。之前都是用原生js的XMLHttpRequest写的请求
XMLHttpRequest方式
xhr.open("POST", uri, true);

xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200) {
// Handle response.
alert(xhr.responseText); // handle response.
}
};
fd.append('myFile', file);
// Initiate a multipart/form-data upload
xhr.send(fd);

其实jquery的ajax也可以支持到的，关键是设置：processData 和 contentType 。
ajax方式

var formData = new FormData();
var name = $("input").val();
formData.append("file",$("#upload")[0].files[0]);
formData.append("name",name);
$.ajax({
url : Url,
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(responseStr) {
if(responseStr.status===0){
console.log("成功"+responseStr);
}else{
console.log("失败");
}
},
error : function(responseStr) {
console.log("error");
}
});
