Lets say i have this HTML code:
<a href="mysite.com" rel="cookie"></a>
<a href="mysite.com" rel="cake"></a>
<a href="mysite.com" rel="cookie"></a>
Is there a quick way to select only the 2 a tags with the cookie rel value.
I did manage to do it using for loop and checking the value on each element, but is there a shorter way?
你可以试试
document.querySelectorAll("a[rel=cookie]");
If you don't mind using a JavaScript library, you can use jQuery
var cookies = $('a[rel="cookie"]')
more info on jQuery selectors: http://api.jquery.com/category/selectors/
This has the added benefit of working with older browsers.
For modern browsers use querySelectorAll
like
var els;
if(document.querySelectorAll){
els = document.querySelectorAll('a[rel="cake"]')
} else {
//use a loop
}
