讲过利用jquery ajax与php实现图片上传,下面我介绍利用php ajax实现各种文件无刷新上传,直接放实例希望给各位同学有帮助,可以批量进行添加上传,简单方便,代码如下:
- <script type="text/javascript" src="jquery-1.5.1.min.js"></script>
- <script type="text/javascript" >
- 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;
- }
- })
- </script>
- <form id="upform" action="" method="post" enctype="multipart/form-data">
- <input id='fname' size='80' /><br> <input type="file" name="file1"
- id="file1" size="30" /> <input type="button" value="上传"
- onclick="return ajaxFileUpload();" /> <span id="msg"
- style="display: none">UpLoading...</span>
- </form>
- <script type="text/javascript">
- var str = '';
- function ajaxFileUpload(){
- $("#msg")
- .ajaxStart(function(){
- $(this).show();
- });
- /*
- .ajaxComplete(function(){
- $(this).hide();
- });

- $.ajaxFileUpload(
- {
- url:'up_deal.php',
- secureuri:false,
- fileElementId:'file1',
- dataType: 'text',
- //data:{name:'qinmi', id:'123'},
- success: function(data){
- if(data=='error'){
- $('#msg').html("<span style='color:red'>上传失败</span>");
- }else{
- $('#msg').html("<span style='color:green'>上传成功</span>");
- str += data+'@';
- $('#fname').val(str);
- }
- }
- }
- );
- return false;
- }
- </script>
up_deal.php,代码如下:
- <?php
- if ((($_FILES["file1"]["type"] == "image/gif")
- || ($_FILES["file1"]["type"] == "image/jpeg")
- || ($_FILES["file1"]["type"] == "image/bmp")
- || ($_FILES["file1"]["type"] == "image/pjpeg"))
- && ($_FILES["file1"]["size"] < 100000)){//100KB
- $extend = explode(".",$_FILES["file1"]["name"]);
- $key = count($extend)-1;
- $ext = ".".$extend[$key];
- $newfile = time().$ext;
- //开源代码phpfensi.com
- if(!file_exists('upload')){mkdir('upload');}
- move_uploaded_file($_FILES["file1"]["tmp_name"],"upload/" . $newfile);
- @unlink($_FILES['file1']);
- echo $newfile;
- }else {
- echo 'error';
- }
- ?>
