的图片。
The following hides images that have Stud_Btn
in their id.
$('img[id^="Stud_Btn"]').hide();

和 Stud_Btn234
,它仍会隐藏它。 ^究竟意味着什么?

and Stud_Btn234
, it will still hide it. What does "^" really mean?
它不仅可以用于比较吗?或者它有其他用途吗?
Can it not only be used for comparison? Or does it have other uses?
推荐答案
[attr ^ = val]
一个CSS选择器,意思是:
[attr^=val]
a CSS selector that means:
类似于 [attr $ = val]
,相反,查找以 val
结尾的属性。
It's similar to [attr$=val]
, which does the opposite, looking for an attribute ending with val
.
