jQuery实现简单的文件上传进度条效果

text-align: center;
background-color:#ccc;
cursor:wait;
}
.confirm{
margin-left:40%;
}
.cancel{
margin-left:10px;
}

jQuery代码：

$(function (){
var $uploadSpan = $('.upload-span');
var $uploadMask = $('.upload-mask');
var $uploadContent = $('.upload-component');
var $closeConfirmCancel = $('.upload-close-span,.confirm,.cancel');
var $uploadTextSpan = $('.upload-text');
function showMask(){
$(".upload-mask,.upload-component").css({display:'block'});
progressBar();
$uploadSpan.off('click',showMask);
}
function hiddenMask(){
$uploadMask.css({display:'none'});
$uploadSpan.on('click',showMask);
}
function closeConfirmCancel(){
$uploadContent.css({display:'none'});
$uploadTextSpan.text('').next().css({width:0});
hiddenMask();
}
// 模拟进度
function progressBar(){
var max =100;
var init =0;
var uploaded;
var test = setInterval(function(){
init +=5;
uploaded = parseInt(init / max *100)+'%';
$uploadTextSpan.text(uploaded).next().css({width:uploaded});
if(init ===100){
clearInterval(test);
$uploadTextSpan.text('上传完成');
$('.confirm-cancel span').css({cursor:'pointer'});
$('.confirm').css({backgroundColor:'rgb(111,197,293)'});
$('.cancel').css({backgroundColor:'rgb(175,194,211)'})
$closeConfirmCancel.on('click',closeConfirmCancel);
}
else{
$closeConfirmCancel.off('click',closeConfirmCancel);
$('.upload-close-span').on('click',function(){
clearInterval(test);
closeConfirmCancel();
});
}
},1000);
}
$uploadSpan.on('click',showMask);
})
