jquery 'attribute contains' selector with a dynamic value

Question

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_\"+questi

Answer 1

You have error:

var questionId = 7674;
$("tr[id*='quiz_question_" + questionId + "']");

Notes:

1. Please use var to declare variables.
2. questionId is a variable. It is not part of the selector. You should concatenate questionId to the string.

Answer 2

Yep, you almost had it:

var selector = "tr[id*='quiz_question_" + questionId + "']";
$(selector)
