• 如何计算每支 j的总时间?
原标题:How to calculate total time for each loop in jQuery?

考虑重复诉讼

setInterval(function(){
$( .test ).each(function(idx){
    var duration = 1000;
    $(this).delay(duration*idx);
    Some stuff here
});
}, 4000);

我如何能够动态计算用于内部休息的时间总数,以制定<条码>。

这里,如果我们有4个包含<条码>测试<>/代码>的元素,则该周期完全使用<条码>、>Interval<4000。 我如何能够作出变数,以动态方式确定这一价值? 例如,当我们有6个要素时,就设置了<代码>6000。

我的问题是,我无法使用<代码>duration*idx在setInterval上的价值,因为它位于idx功能之内。

最佳回答

http://api.jquery.com/length/“rel=“nofollow”>。

var total  = $( .test ).length,
    timer  = 1000,
    result = parseInt(timer*total);

之后,你们采取行动!

<>.size(.length Property;然而,。 优先选择财产是因为没有职能电话的间接费用。

问题回答

最简单的方法是在开端到拉帕斯之间放大。

start = new Date().getTime();
 elapsed = new Date().getTime() - start;
