How can I select all elements whose id starts with "player_"?
I have multiple elements like this:
<div id="player_290x3dfda">text</div>
Every id has a unique stamp on it. How can I select all those elements, either with jQuery or with pure CSS?
回答1:
Normally you would select IDs using the ID selector #, but for more complex matches you can use the attribute-starts-with selector (as a jQuery selector, or as a CSS3 selector):
div[id^="player_"]
If you are able to modify that HTML, however, you should add a class to your player divs then target that class. You'll lose the additional specificity offered by ID selectors anyway, as attribute selectors share the same specificity as class selectors. Plus, just using a class makes things much simpler.

try this:
$('div[id^="player_"]')

You can use meta characters like * (http://api.jquery.com/category/selectors/).
So I think you just can use $('#player_*').
In your case you could also try the "Attribute starts with" selector:
http://api.jquery.com/attribute-starts-with-selector/: $('div[id^="player_"]')
回答4:
$('div[id ^= "player_"]');
This worked for me..select all Div starts with "players_" keyword and display it.
