jquery - 分段进度条 (jQuery UI)

Question

我正在尝试将 jQuery UI 进度条划分为多个部分。

有人知道我会怎么做吗？

（我目前正在使用背景图像，但这不实用。）

Answer 1

这是我正在研究的原型......

CSS：

div { margin:10px 10px 0px 10px; height:24px; }
div.progressContainer { clear:both; display:block; }
label { float:left; width:200px; display:block; }
input { float:left; width:100px; text-align:center; display:inline; }
input[type=button] { margin-right:1.5px; }

HTML：

<!-- Options -->
<div> <!-- Maximum -->
    <label> Maximum ProgressBar Value </label>
    <input id="max" type="text" value="100" />
</div>
<div> <!-- Initial Value -->
    <label> Initial Value </label>
    <input id="val" type="text" value="43" />
</div>
<div> <!-- Width -->
    <label> ProgressBar Width </label>
    <input id="width" type="text" value="304" />
</div>
<div> <!-- Height -->
    <label> ProgressBar Height </label>
    <input id="height" type="text" value="30" />
</div>
<div> <!-- Multiply -->
    <label> Segmented ProgressBar </label>
    <input id="seg" type="text" value="4" />
</div>
<!-- Create ProgressBar by given options -->
<div>
    <input type="button" value="Create" />
</div>
<!-- ProgressBar Container -->
<div class="progressContainer"> </div>
<!-- Action Buttons -->
<div>
    <input type="button" value="Start" /> <input type="button" value="Stop" /> <input type="button" value="Reset" />
</div>
