在jQuery动画中仅执行一次完整功能?
问题描述:
我正在尝试为某些文本的字体大小设置动画:
I'm trying to animate the font size of some text:
$("p").delay(500).animate({
"font-size": "+=50"
}, 1000, function() {
alert("Done");
});
我想在对<p>
进行动画处理后做一些事情,在示例中为alert
,但是令人惊讶的是,它为每个<p>
运行了它,这不是我想要的.有没有办法使它只运行一次还是不可能?
I want to do something after animating the <p>
s, which in the example is alert
, but it surprisingly runs it for each <p>
, and that's not what I want. Is there a possible way to make it just run once or is it not possible?
答
var $p = $("p");
var lastIndex = $p.length - 1;
$p.delay(500).animate({
"font-size": "+=50"
}, 1000, function() {
if ($p.index($(this)) == lastIndex) {
alert("Done");
}
})
