你可以在程序中,每到一个位置就设置一下进度条的长度。

在web上传中,实现进度条是间很COOL的事情,但是很多时候,为了实现进度条我们需要做的工作量会很大,现在采用FLASH可以很方便的使用,但是您想过通过JQUERY来实现吗?
Js代码如下
jQuery.extend({
createUploadIframe: function(id, uri){
var frameId = 'CrazyCoder_CN' + id;
if(window.ActiveXObject) {
var io = document.createElement('<iframe id="' + frameId + '" name="' + frameId + '" />');
if(typeof uri== 'boolean'){
io.src = 'javascript:false';
}
else if(typeof uri== 'string'){
io.src = uri;
}
}
else {
var io = document.createElement('iframe');
io.id = frameId;
io.name = frameId;
}
io.style.position = 'absolute';
io.style.top = '-1000px';
io.style.left = '-1000px';
document.body.appendChild(io);
return io
},
ajaxUpload: function(s) {
// 初始化
s = jQuery.extend({}, jQuery.ajaxSettings, s);
var id = new Date().getTime()
io = jQuery.createUploadIframe(id, s.secureuri)
// Watch for a new set of requests
