Let's say that i have a variable questionId
which is an integer, and i want to find tr
elements that have the fragment ("question_"+questionId
) in their id. How can i do this? I thought that i would be able to do it with the jquery 'attribute contains' selector.
Eg, this works, for a non-dynamic value,
$("tr[id*='quiz_question_7674']")
but, i can't work out how to plug the variable value in there. This doesn't work for example:
questionId = 7674;
$("tr[id*='quiz_question_'+questionId]")
Any ideas anyone? Is there a better way than 'attribute contains' to do it? I have the feeling i'm missing something obvious.
thanks, max
EDIT - SOLVED. doh, i am indeed missing something obvious. I keep forgetting that it's just a string, nothing more:
$("tr[id*='quiz_question_"+questionId+"']")
You have error:
var questionId = 7674;
$("tr[id*='quiz_question_" + questionId + "']");
Notes:
Yep, you almost had it:
var selector = "tr[id*='quiz_question_" + questionId + "']";
$(selector)
