由于某种原因,我的文件上传脚本无法正常工作,我完全不明白为什么:?该脚本设法发送文件,但我无法跟踪进度或状态更改。我试图注释掉不必要的位用于调试,但它仍然不起作用。
如果有人能指出我的错误,我将永远感激并给你一个虚拟饼干

尝试更改此内容:
xmlhttp.addEventListener('readystatechange', function(){
if(this.readystate === 4){
if(this.status === 200){
//uploaded = JSON.parse(this.response);
//if(typeof o.options.finished === 'function'){
o.options.finished();
//}
} else {
//if(typeof o.options.error === 'function'){
o.options.error();
//}
}
}
});
对此:
xmlhttp.onreadystatechange = function() {
if(xmlhttp.readystate === 4){
if(xmlhttp.status === 200){
//uploaded = JSON.parse(this.response);
//if(typeof o.options.finished === 'function'){
o.options.finished();
//}
} else {
//if(typeof o.options.error === 'function'){
o.options.error();
//}
}
}
});

我用'math.round()'代替'Math.round()'。一个非常简单的错误,但它阻止了脚本的其余部分执行。感谢Marvin Medeiros总是检查错误控制台的声音建议
var app = app || {};
(function(o){
"use strict"
var ajax, getFormData, setProgress;
ajax = function(data){
var xmlhttp = new XMLHttpRequest(), uploaded;
xmlhttp.addEventListener('onreadystatechange', function(){
if(xmlhttp.readystate === 4){
if(xmlhttp.status === 200){
uploaded = JSON.parse(this.response);
if(typeof o.options.finished === 'function'){
o.options.finished();
}
} else {
if(typeof o.options.error === 'function'){
o.options.error();
}
}
}
});
xmlhttp.upload.addEventListener('progress', function(event){
var percent;
if(event.lengthComputable === true){
percent = Math.round(event.loaded / event.total * 100);
setProgress(percent);
}
});
xmlhttp.open('POST', o.options.processor);
xmlhttp.send(data);
}
getFormData = function(src){
var data = new FormData(), i;
for(i=0;i<src.length;i++){
data.append('file[]',src[i]);
}
data.append('formSent',true);
return data;
}
setProgress = function(val){
$('#pb').animate({width:val+"%"},10);
$('#pt').html(val+"%");
}
o.uploader = function(opt){
o.options = opt;
if(o.options.files !== undefined){
ajax(getFormData(o.options.files.files));
}
}
}(app));

尝试一下:
xmlhttp.addEventListener('readystatechange', function(e){
if(e.currentTarget.readyState === 4){
if(e.currentTarget.status === 200){
o.options.finished();
} else {
o.options.error();
}
}
});
