Cant select checkbox dynamically
Posted on 2016-10-03
Hi,
I have an ajax call that returns a number of values.
With it I am assigning a value to an input text field (this works fine)
and trying to show a checkbox as 'checked'
I've tried a number of methods to try and check the checkbox dynamically but it simply isn't.
Is there something I'm missing?
using Jquery 1.9+
bootstrap 3
html segment
Script segment

I see nothing wrong with the line that checks the checkbox. However,
Try reversing the order of the two lines you've posted and see if the checkbox gets checked. If not, can you please post a link to the live page?
One thing to consider is if there is another element with the id horsepower_check. Ids must be unique and when there are duplicates, only one is targeted. I believe it's the first that gets targeted because the DOM would not accept the second. But it could be the latter.
Also, have you validated your HTML? (Appears to be down at the moment!)

Javascript identifiers must start with a letter, $, or _ and they can contain letters, digits, _ and $. But they cannot contain any other punctuation, especially one that is reserved.

Kim's correct... commenting out the first jQuery operation causes it to work.
