个人使用总结:
【Progresbar插件很重要】
JQuery Progress Bar是基于JQuery开发的进度条插件,秉承了JQuery的简约哲学。
不仅容易使用,而且可以轻松定制外观。对于使用了JQuery框架的项目来说,
需要使用进度条控件时这是一个不错的选择。
JQuery Progress Bar与常规插件一样,只要用选择器选择一个HTML元素后,
直接调用插件的公开方法即可。它提供的公开方法名称为progressBar()。
那么,当HTML页面上有一个id为progress1的元素时,可以这样初始化该控件:
$("#progress1").progressBar();
它的构造函数可以接收如下表所示的参数。
方法及参数 |
用途 |
progressBar() |
按默认设置初始化一个进度条 |
progressBar(persent) |
按默认设置初始化或更新一个进度条,设置进度条的百分比至persent%. |
progressBar(config) |
按config中指定的设置初始化一个进度条,百分比为0%。注意不要在初始化之后使用该方法来更改进度条的设置,否则可能引起显示不正常。 |
progressBar(persent,config) |
按config中指定的设置初始化一个进度条,百分比为persent%。注意不要在初始化之后使用该方法来更改进度条的设置,否则可能引起显示不正常。 |
其中,config参数是一个哈希结构对象,它包含了如下属性用于设置进度条的外观特性
属性 |
用途 |
increment |
设置进度条每步的增长度。默认值为2。 |
speed |
设置进度条初始化时动态滑动效果的速度。默认值为15。这个值越大,则滑动速度越慢。 |
showText |
设置是否显示百分比标识文字。默认值为ture,即显示百分比文字标识。 |
boxImage |
设置边框图片。默认值为images/progressbar.gif。如需定制边框,则修改该属性,指向要使用的图片即可。 |
barImage |
设置进度标识图片。默认值为images/progressbg_green.gif。如需定制,则修改该属性,指向要使用的图片即可。这个图片分类两节,前半节用于标识完成进度,后半截用于标识剩余未完成进度。两节长度相等,且等于进度条的宽度。 |
width |
设置进度条的宽度,这个值必须与barImage和boxImage所指向的图片相适应。默认值为120。 |
height |
设置进度条的高度,这个值必须与barImage和boxImage所指向的图片相适应。默认值为12。 |
$(document).ready(function() {
$("#spaceused1").progressBar();
$("#spaceused2").progressBar({ barImage: 'images/progressbg_yellow.gif'} );
$("#spaceused3").progressBar({ barImage: 'images/progressbg_orange.gif', showText: false} );
$("#spaceused4").progressBar(65, { showText: false, barImage: 'images/progressbg_red.gif'} );
$("#uploadprogressbar").progressBar();
});
