AjaxUpload

代码
            <script>
                jQuery(
function(){                    
                    
var upload = new AjaxUpload(jQuery('#test4'), {
                        action: 
'upload-test.php',
                        name: 
'woohoo-custom-name',
                        data: {
                            
'key1'"This data won't be sent, we will overwrite it."
                        },
                        autoSubmit: 
false,
                        responseType: 
'json',
                        onChange: 
function(file, ext){
                        },
                        onSubmit: 
function(file, ext){
                            
// Allow only images. You should add security check on the server-side.
                            if (ext && /^(jpg|png|jpeg|gif)$/i.test(ext)) {                            
                                
this.setData({
                                    
'key1''This should be alerted',
                                    
'key2''...'
                                });
                            } 
else {
                                alert(
'not image');
                                
return false;
                            }                            
                        },
                        onComplete: 
function(file, response){
                            
this.disable();
                            alert(response.post.key1);
                        }
                    });
                    jQuery(
'#test4upload').click(function(){
                        upload.submit();
                        upload.enable();
                        
return false;
                    });
                });                    
            
</script>


这样就可以看到选择的文件了。 

    <div style="position:relative;">  
    <input id="fuploadImportExcel" name="fuploadImportExcel" size="30" type="file"  /> 
    <span id="SelectFile" style="position:absolute; top:2px; left:5px; line-height:20px;"></span>
    </div>

onChange: function(file,ext) { 

 $("#SelectFile").html(file);

 }, 

注: 默认的必须有文件才可以提交。如果文件是选填,则用户没选择文件就不可以提交。 我更新了一下ajaxupload.js
