당신이 AjaxFileUploader를 사용하지 않는 이유를 보유하고 당신을 위해 도움이 될 수 있습니다, 그것은 사용하기 쉬운
대상에 접근하려면 다음 단계를 따르십시오.
1 단계 :
head 태그에 dRAG Jquery 파일.
이 코드를 자바 스크립트 파일에 추가하고 페이지의 머리 부분으로 드래그하십시오.
jQuery.extend({
createUploadIframe: function (id, uri) {
//create frame
var frameId = 'jUploadFrame' + id;
var iframeHtml = '<iframe id="' + frameId + '" name="' + frameId + '" style="position:absolute; top:-9999px; left:-9999px"';
if (window.ActiveXObject) {
if (typeof uri == 'boolean') {
iframeHtml += ' src="' + 'javascript:false' + '"';
}
else if (typeof uri == 'string') {
iframeHtml += ' src="' + uri + '"';
}
}
iframeHtml += ' />';
jQuery(iframeHtml).appendTo(document.body);
return jQuery('#' + frameId).get(0);
},
createUploadForm: function (id, fileElementId, data) {
//create form
var formId = 'jUploadForm' + id;
var fileId = 'jUploadFile' + id;
var form = jQuery('<form action="" method="POST" name="' + formId + '" id="' + formId + '" enctype="multipart/form-data"></form>');
if (data) {
for (var i in data) {
jQuery('<input type="hidden" name="' + i + '" value="' + data[i] + '" />').appendTo(form);
}
}
var oldElement = jQuery('#' + fileElementId);
var newElement = jQuery(oldElement).clone();
jQuery(oldElement).attr('id', fileId);
jQuery(oldElement).before(newElement);
jQuery(oldElement).appendTo(form);
//set attributes
jQuery(form).css('position', 'absolute');
jQuery(form).css('top', '-1200px');
jQuery(form).css('left', '-1200px');
jQuery(form).appendTo('body');
return form;
},
ajaxFileUpload: function (s) {
// TODO introduce global settings, allowing the client to modify them for all requests, not only timeout
s = jQuery.extend({}, jQuery.ajaxSettings, s);
var id = new Date().getTime()
var form = jQuery.createUploadForm(id, s.fileElementId, (typeof (s.data) == 'undefined' ? false : s.data));
var io = jQuery.createUploadIframe(id, s.secureuri);
var frameId = 'jUploadFrame' + id;
var formId = 'jUploadForm' + id;
// Watch for a new set of requests
if (s.global && !jQuery.active++) {
jQuery.event.trigger("ajaxStart");
}
var requestDone = false;
// Create the request object
var xml = {}
if (s.global)
jQuery.event.trigger("ajaxSend", [xml, s]);
// Wait for a response to come back
var uploadCallback = function (isTimeout) {
var io = document.getElementById(frameId);
try {
if (io.contentWindow) {
xml.responseText = io.contentWindow.document.body ? io.contentWindow.document.body.innerHTML : null;
xml.responseXML = io.contentWindow.document.XMLDocument ? io.contentWindow.document.XMLDocument : io.contentWindow.document;
} else if (io.contentDocument) {
xml.responseText = io.contentDocument.document.body ? io.contentDocument.document.body.innerHTML : null;
xml.responseXML = io.contentDocument.document.XMLDocument ? io.contentDocument.document.XMLDocument : io.contentDocument.document;
}
} catch (e) {
jQuery.handleError(s, xml, null, e);
}
if (xml || isTimeout == "timeout") {
requestDone = true;
var status;
try {
status = isTimeout != "timeout" ? "success" : "error";
// Make sure that the request was successful or notmodified
if (status != "error") {
// process the data (runs the xml through httpData regardless of callback)
var data = jQuery.uploadHttpData(xml, s.dataType);
// If a local callback was specified, fire it and pass it the data
if (s.success)
s.success(data, status);
// Fire the global callback
if (s.global)
jQuery.event.trigger("ajaxSuccess", [xml, s]);
} else
jQuery.handleError(s, xml, status);
} catch (e) {
status = "error";
jQuery.handleError(s, xml, status, e);
}
// The request was completed
if (s.global)
jQuery.event.trigger("ajaxComplete", [xml, s]);
// Handle the global AJAX counter
if (s.global && ! --jQuery.active)
jQuery.event.trigger("ajaxStop");
// Process result
if (s.complete)
s.complete(xml, status);
jQuery(io).unbind()
setTimeout(function() {
try {
jQuery(io).remove();
jQuery(form).remove();
} catch (e) {
jQuery.handleError(s, xml, null, e);
}
}, 100)
xml = null
}
}
// Timeout checker
if (s.timeout > 0) {
setTimeout(function() {
// Check to see if the request is still happening
if (!requestDone) uploadCallback("timeout");
}, s.timeout);
}
try {
var form = jQuery('#' + formId);
jQuery(form).attr('action', s.url);
jQuery(form).attr('method', 'POST');
jQuery(form).attr('target', frameId);
if (form.encoding) {
jQuery(form).attr('encoding', 'multipart/form-data');
}
else {
jQuery(form).attr('enctype', 'multipart/form-data');
}
jQuery(form).submit();
} catch (e) {
jQuery.handleError(s, xml, null, e);
}
jQuery('#' + frameId).load(uploadCallback);
return { abort: function() { } };
},
uploadHttpData: function (r, type) {
var data = !type;
data = type == "xml" || data ? r.responseXML : r.responseText;
// If the type is "script", eval it in global context
if (type == "script")
jQuery.globalEval(data);
// Get the JavaScript object, if JSON is used.
if (type == "json")
eval("data = " + data);
// evaluate scripts within html
if (type == "html")
jQuery("<div>").html(data).evalScripts();
return data;
}
})이 같은
뭔가 :
<script src="Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="Scripts/fileUploader.js" type="text/javascript"></script>
2 단계 : 몸 페이지에이 태그를 추가합니다.
<input id="fileToUpload" type="file" size="45" name="fileToUpload" />
<button id="btnUploadNewLicense" onclick="return ajaxFileUpload('New');">
Upload</button><br />
<div id="loading" style="display: none;">
Please wait...</div>
3 단계 : 은 프로젝트 루트에 "FileUpload.ashx"라는 이름의 일반 핸들러 파일을 추가, 는 "FileUplod.ashx"에이 다음 코드를 추가
public void ProcessRequest(HttpContext context)
{
HttpRequest request = context.Request;
HttpResponse response = context.Response;
string action = request["Action"];
switch (action)
{
case "New":
string result = "failed";
try
{
string fileName = SaveCaper(context);
result = "successed";
response.Write("{\"result\":" + result.ToString().ToLower() + "}");
}
catch
{
response.Write("{\"result\":" + result.ToString().ToLower() + "}");
}
break;
default:
throw new Exception("Invalid sort column name!.");
}
}
private string SaveCaper(HttpContext context)
{
string fileName = string.Empty;
string path = context.Server.MapPath("~/NewImages");
if (!Directory.Exists(path))
Directory.CreateDirectory(path);
try
{
var file = context.Request.Files[0];
if (HttpContext.Current.Request.Browser.Browser.ToUpper() == "IE")
{
string[] files = file.FileName.Split(new char[] { '\\' });
fileName = files[files.Length - 1];
}
else
{
fileName = file.FileName;
}
string strFileName = fileName;
fileName = Path.Combine(path, fileName);
try
{
file.SaveAs(fileName);
}
catch (Exception exp)
{
//log the exception
}
}
catch (Exception exp)
{
//log the exception
}
return fileName;
}
public bool IsReusable
{
get
{
return false;
}
}
또한 당신이 필요 System.IO를 처리기 코드의 맨 위에 추가하십시오.
4 단계 : 당신의 JS 파일 프로토 타입
<script language="javascript" type="text/javascript">
$(document).ready(function() {
function ajaxFileUpload(mode) {
var fupl = 'fileToUpload';
var fileName = $('#fileToUpload').val();
if (fileName == "" || fileName == null)//if user doesn't select an image
{
$("#loading").html("");
$("#loading").append("<br/><b>Please select an image...</b>");
}
else {
var vars = fileName.split("."); //get file extension.
if (vars[1].toString().toLowerCase() != "jpg") {//check the file extension.
$("#loading").html("");
$("#loading").append("<br/>The image format is not valid !.");
return false;
}
$("#loading").ajaxStart(function() { $('#dialogUpdateLicense :input').attr('disabled', true); $(this).show(); })
.ajaxComplete(function() { $('#dialogUpdateLicense :input').removeAttr('disabled'); });
$("#loading").html("");
$("#loading").append("<br/><b>Please wait...</b>");
$.ajaxFileUpload
({
url: 'FileHandler.ashx',
secureuri: false,
fileElementId: 'fileToUpload',
dataType: 'json',
data: { Action: mode },
success: function (data) {
if (data.result == "successed")
$("#loading").html("The image uploaded successfully!.");
},
error: function (data, e) {
$("#loading").html("An error occured!.");
}
})
}
return false;
}
</script>
모든 일을 시험하고 내가 당신을 도움이되기를 바랍니다 나
제대로 작동 후 머리에이 스크립트를 추가합니다.
당신은'WebForm' 또는'MVC'에 있습니까 ?? – Bellash
