jquery 'attribute contains' selector with a dynamic value
javascript, jquery
Solution
You have error:
var questionId = 7674;
$("tr[id*='quiz_question_" + questionId + "']");
Notes:
- Please use var to declare variables.
- questionId is a variable. It is not part of the selector. You should concatenate questionId to the string.
Problem
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+"']")
