目前有一米使用低于标准但效果良好。
$("#topperAtBaseLevel:visible, #lowerAtBaseLevel:visible, #midAtBaseLevel").hide();
any optimised code? (i cant use same class)
i mean how to use :visible
rightly?

这是实现你所追求的目标的途径。 你们正在正确、高效地利用甄选者。
如果你维持一系列需要隐藏的政党的身份证,然后以动态方式建造你的挑选人,那么你就会更快地做到这一点。 (即使选择人可能更长,这也将会更快。) 国际发展学会的选择非常快。
但是,是否需要优化? 我们谈论的是,从闪光到杜布尔的照明速度快。 一位超级班子将做你所做的事。
这部法律似乎完美无缺;你正在使用:是正确的。
http://api.jquery.com/visible-selector/“rel=“nofollow noreferer” Query:visible selectedor help page, 如果你想要确切知道如何运作,但用几句话来说,它选择了明显的要素 =
我可以认为:
$([id$=“AtBaselevel”]:visible .hide();
这将与任何在<代码>AtBaselevel中填写的识别资料相匹配。 更糟糕的是,时间较短并不意味着速度更快,因为国际发展学会的考量正像现在这样快。 以补计的遴选人并不选择。
你可以这样做:
$("#topperAtBaseLevel, #lowerAtBaseLevel, #midAtBaseLevel").filter(":visible").hide();
然而,由于这种结果,所有隐藏的物品,即:.hide()
,就隐藏的元素而言,都是罚款,没有错,因此只能是:
$("#topperAtBaseLevel, #lowerAtBaseLevel, #midAtBaseLevel").hide();
