Javascript、jQuery 元素选择器

Question

I can't understand what this selector selects actually:

var x=$("a[href*='y']")

Could you guys explain it me in plain English.

Thanx in advance Dhiaa

Answer 1

*= means contains, so in this case it is selecting all anchor ( a ) tags that contain y

See documentation on jquery selectors here.

Answer 2

a[href*='y'] matches any elements that:

1. Are a elements, and
2. Have an href attribute that contains y ( [attr*=...] is an attribute 'contains' substring selector; spec , jQuery )

Answer 3

This selector selects an with attribute, contains href='y'. That means that you select some link () which leads (href) to y

Answer 4

它选择每个 href 属性值包含“y”的元素。
