如何只用blueimp文件上传插件上传文件一次? [英] How to upload a file only once with blueimp file upload plugin?
问题描述
我正在使用 bluimp jQuery-File-Upload-plugin 。选择一些文件并上传它们是没有问题的,但是当我想上传另一个文件而不刷新页面时,第一个文件就会重新上传。我的问题是如何在上传后取消文件。这里是我的源代码
Javascript:
$('#MappeFile ').fileupload({
dataType:'json',
autoUpload:false,
maxNumberOfFiles:undefined,
maxFileSize:6000000,
minFileSize:undefined,
acceptFileTypes:/.+$/i,
url:/ajax/UploadFile.php,
add:function(e,data){
$(#testUploadButton) .on(click,function(){
$('#progress .bar')。show();
if($ .browser.msie&& parseInt($。browser。版本10)< 10){
$('#progress.bar').css({
background:url(images / progressbar.gif)no-repeat,
width:100%
})
} else {
$('#progress .bar')。css({
'b ackground-color':#2694E8,
'width':'0%'
});
}
data.submit();
})
},
change:function(e,data){
$ .each(data.files,function(index,file){
console。 info('Selected file:'+ file.name);
filesCount ++;
});
,
drop:function(e,data){
$ .each(data.files,function(index,file){
console.info('Selected file: '+ file.name);
filesCount ++;
});
},
done:function(e,data){
$ .each(data.result,function(index,file){
vOutput =< tr> ;
vOutput + =< td>+ file +< / td>;
vOutput + =< tr>;
$(#MappeFileListe) .append(vOutput);
filesUploaded ++;
if(filesCount == filesUploaded){
filesUploaded = 0;
filesCount = 0;
$('#progress。 bar')。hide();
}
});
},
progressall:function(e,data){
var progress = parseInt(data.loaded / data.total * 100,10);
$('#progress .bar')。css('width',progress +'%');
}
});
HTML:
< div id =KundeMappe>
< form id =MappeFile>
< input type =fileid =MappeFileSelectname =files []data-url =ajax / UploadFile.phpmultiple />
< div id =progress>
< div class =barstyle =width:0%;>< / div>
< / div>
< input type =buttonclass =neuButtonvalue =uploadid =testUploadButton/>
< / form>
< table id =MappeFileListe>< / table>
< / div>
我自己找到了答案 - 点击上传后的按钮事件:
pre code add:function(e,data){
$(#testUploadButton ).on(click,function(){
$('#progress .bar')。show(); $ b $ if($ .browser.msie&& parseInt($。 browser.version,10)< 10){
$('#progress .bar').css({
background:url(images / progressbar.gif)no-repeat,
width:100%
})
} else {
$('#progress .bar')。css({
'background-color ':#2694E8,
'width':'0%'
});
}
data.submit();
$(#testUploadButton)。off(click)
})
},
I'm using the bluimp jQuery-File-Upload-plugin . It's no problem to select some files and upload them, but when I want to upload another files without refreshing the page, the first ones are getting uploaded again. My question is how can I "unset" files after they are uploaded. Here is my sourcecode
Javascript:
$('#MappeFile').fileupload({
dataType : 'json',
autoUpload : false,
maxNumberOfFiles : undefined,
maxFileSize : 6000000,
minFileSize : undefined,
acceptFileTypes : /.+$/i,
url : "/ajax/UploadFile.php",
add : function(e, data) {
$("#testUploadButton").on("click", function() {
$('#progress .bar').show();
if ($.browser.msie && parseInt($.browser.version, 10) < 10) {
$('#progress .bar').css({
"background" : "url(images/progressbar.gif) no-repeat",
"width" : "100%"
})
} else {
$('#progress .bar').css({
'background-color' : "#2694E8",
'width' : '0%'
});
}
data.submit();
})
},
change : function(e, data) {
$.each(data.files, function(index, file) {
console.info('Selected file: ' + file.name);
filesCount++;
});
},
drop: function(e, data) {
$.each(data.files, function(index, file) {
console.info('Selected file: ' + file.name);
filesCount++;
});
},
done : function(e, data) {
$.each(data.result, function(index, file) {
vOutput = "<tr>";
vOutput += "<td>" + file + "</td>";
vOutput += "<tr>";
$("#MappeFileListe").append(vOutput);
filesUploaded++;
if (filesCount == filesUploaded) {
filesUploaded = 0;
filesCount=0;
$('#progress .bar').hide();
}
});
},
progressall : function(e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$('#progress .bar').css('width', progress + '%');
}
});
HTML:
<div id="KundeMappe">
<form id="MappeFile">
<input type="file" id="MappeFileSelect" name="files[]" data-url="ajax/UploadFile.php" multiple/>
<div id="progress">
<div class="bar" style="width: 0%;"></div>
</div>
<input type="button" class="neuButton" value="upload" id="testUploadButton"/>
</form>
<table id="MappeFileListe"></table>
</div>
I found the answer myself - It's enough to unbind the click event of the button after upload:
add : function(e, data) {
$("#testUploadButton").on("click", function() {
$('#progress .bar').show();
if ($.browser.msie && parseInt($.browser.version, 10) < 10) {
$('#progress .bar').css({
"background" : "url(images/progressbar.gif) no-repeat",
"width" : "100%"
})
} else {
$('#progress .bar').css({
'background-color' : "#2694E8",
'width' : '0%'
});
}
data.submit();
$("#testUploadButton").off("click")
})
},
