jQuery动画和属性值百分比 [英] jQuery animate and property values in percentage

问题描述

我试图为div设置动画，我尝试在其他地方使用某些值进行检索，我知道这个值是正确的，因为我已打印出输出...所以我想知道为什么它不能正常工作？

I trying to animate a div and I try to use some value retreived somewhere else, I know the value to be correct because I've printed out the output... so I'm wondering why doesn't it work properly?

animateBar(percentage.toFixed(2)+'%');

[ . . . ]

function animateBar(percentage)
{
    $('#innerBox').animate({width: percentage}, 3000);
}

推荐答案

好像是使用动画百分比的错误。 http://bugs.jquery.com/ticket/10669

It seems as though theres a bug with using a percentage with animate. http://bugs.jquery.com/ticket/10669

我建议计算自己添加的像素数，这可能有效：

I would suggest calculating the number of pixels to add yourself, something like this may work:

percent = 0.25;
add_width = (percent*$('#innerBox').parent().width())+'px';
$('#innerBox').animate({'width': '+='+add_width}, 3000);
