页面加载时的 Twitter 引导进度条动画 [英] Twitter bootstrap progress bar animation on page load

问题描述

我有一个包含多个引导进度条的页面.设置它们的值最初工作正常.虽然我希望进度条在用户打开页面时动画/过渡到它们的特定状态.

当您单击其中一个栏时，此 JS 工作正常.我需要在酒吧的onload"事件上做类似的事情.但是 "onload" 事件对 s 不可用

//动画进度条$('.progress .bar').on("click", function(event) {var me = $(this);perc = me.attr("数据百分比");me.css('width', perc+'%');});

如何在页面加载时为页面上的所有进度条实现这种行为?

解决方案

虽然 Tats_innit 的回答很不错，但由于页面上有多个进度条，所以我不得不采取不同的方式.

这是我的解决方案:

JSfiddle:http://jsfiddle.net/vacNJ/

HTML(示例):

<div class="bar" style="float: left; width: 0%; " data-percentage="60"></div>
<div class="progress progress-success"><div class="bar" style="float: left; width: 0%; " data-percentage="50"></div>

<div class="progress progress-success"><div class="bar" style="float: left; width: 0%; " data-percentage="40"></div>

JavaScript:

setTimeout(function(){$('.progress .bar').each(function() {var me = $(this);var perc = me.attr("数据百分比");var current_perc = 0;var 进度 = setInterval(function() {如果(current_perc>=perc){清除间隔(进度)；} 别的 {current_perc +=1;me.css('width', (current_perc)+'%');}me.text((current_perc)+'%');}, 50);});},300);

@Tats_innit:使用 setInterval() 动态重新计算进度是一个不错的解决方案，谢谢伙计！;)

我的一个朋友为自定义 Twitter 引导程序进度条编写了一个很好的 jquery 插件.这是一个演示:http://minddust.github.com/bootstrap-progressbar/

I have a page with several bootstrap progress bars. Setting their values initially works fine. Though I would like the progress bars to animate/transition to their specific states when a user opens the page.

This JS works fine, when you click on one of the bars. I would need something like that on an "onload" event of the bar. But the "onload" event is not available for s

//animate progress bars
$('.progress .bar').on("click", function(event) {
  var me = $(this);
  perc = me.attr("data-percentage");
  me.css('width', perc+'%');
});

How can I achieve this behavior on page load for all progress bars on a page?

解决方案

While Tats_innit's answer has a nice touch to it, I had to do it a bit differently since I have more than one progress bar on the page.

here's my solution:

JSfiddle: http://jsfiddle.net/vacNJ/

HTML (example):

<div class="progress progress-success">
<div class="bar" style="float: left; width: 0%; " data-percentage="60"></div>
</div>

<div class="progress progress-success">
<div class="bar" style="float: left; width: 0%; " data-percentage="50"></div>
</div>

<div class="progress progress-success">
<div class="bar" style="float: left; width: 0%; " data-percentage="40"></div>
</div>

​

JavaScript:

setTimeout(function(){

    $('.progress .bar').each(function() {
        var me = $(this);
        var perc = me.attr("data-percentage");

        var current_perc = 0;

        var progress = setInterval(function() {
            if (current_perc>=perc) {
                clearInterval(progress);
            } else {
                current_perc +=1;
                me.css('width', (current_perc)+'%');
            }

            me.text((current_perc)+'%');

        }, 50);

    });

},300);

@Tats_innit: Using setInterval() to dynamically recalc the progress is a nice solution, thx mate! ;)

EDIT:

A friend of mine wrote a nice jquery plugin for custom twitter bootstrap progress bars. Here's a demo: http://minddust.github.com/bootstrap-progressbar/
