Javascript制作进度条
这篇文章将详细描述应用Javascript制作两种类型的进度条，并且将核心代码包装起来。放在percent.js
/**
* 绘制简单百分比进度条
* barId 进度条span的ID
* fPercent 完成的百分数
* strCaption 标题
* iHeight 高度
* iUnit 最小单位
* bgcolor 背景颜色
* border 边框样式
* cursor 光标样式
*/
function SimplePercent(barId, fPercent, strCaption, iHeight, iUnit, bgcolor, border, cursor) {
var pBar = document.all(barId);
if (pBar)
{
pBar.title = strCaption + fPercent + "%";
pBar.innerHTML = "";
if (bgcolor){
pBar.style.backgroundColor = bgcolor;
}
if (border == null){
border = "1px solid #000000";
}
pBar.style.border = border;
if (cursor == null){
cursor = "default";
}
pBar.style.cursor = cursor;
if (iHeight == null || iHeight < 1){
iHeight = 1;
}
pBar.style.height = iHeight + "px";
if (iUnit == null || iUnit < 1){
iUnit = 1;
}
pBar.style.width = (iUnit * 100) + "px";
pBar.insertAdjacentHTML("BeforeEnd", "");
}
}
