I added a check box group with one checkbox item.
I am mapping an array to the checkbox item. I need to determine the value of a check box, and if it is checked, with a Click event. In my Javascript, how do I reference the checkbox that was clicked? I tried both $(this)... and Appery(this)... and neither worked.
Thanks
Thanks. However, Appery('name') doesn't seem to be working, or I am not understanding.
Here is a screen shot of the builder, showing the javascript. (category_checkboxes is the Checkbox group, obviously). The next shot is the mapping. Then a shot of a test of the service, so you can see that catid does have values. The next shot is the page in the app in a browser, and the last is the alert. I didn't know if I should use the name of the checkbox group or item, so I tried both.

Hi Fred,
Please post a public link to your app. We would need to take a look.
I sent an email to support, three days ago, with the public link, and the info needed to log into the app. The app has also been shared with support.
I am quite certain that at one time when I chose to run custom javascript on an event, at the top of the edit box, it had "function (value,element)" or something like that - the point being that value and element were sent to the function. I cannot find where I saw that. However, if I could have that sent to the function for the onclick of the check box elements added by mapping an array, that would work well.
I also know that in another place, I was able to use "this.value" to get the value of the element that was clicked on. However, that is not working in this instance.
Somehow, there must be a way to get a reference to the check box that was clicked on. Hopefully, you can help me do that.
Thanks
Hi Fred,
I'm sorry, I don't see your email. Could you please send it again to a href="mailto:support@appery.io" rel="nofollow"support@appery.io/a? What is your app name?
Sorry, I sent the email as a reply to the email I got from the post here. I see now that went to noreply... (Had to look at Outlook Properties to see the actual email address).
I've forwarded the email to a href="mailto:support@appery.io" rel="nofollow"support@appery.io/a. The name of the app is LW-Fred.
Since the app requires a log in, and there is personal information of other people in it, I didn't want to post all the required info here in the forum.
Fred,
Thank you, now I can see it. We'll test this.
No answers here, just a report on what I'm finding. I have been doing some experimenting, and have found the this:
I would expect just plain
this.value
to give me the value. It does not. If I have a check box that is not generated by mapping an array to a check box, then it does.
$(this).text() gives me the text shown on the screen for the check box I've clicked. So this is unique for each check box. This makes me think $(this)... should work for other methods, but it doesn't, as the following show
$(this).val() gives a blank. (I added JS to run on output mapping, where the function is: function (value,element) { ...} and doing an alert on value does give each unique value as they are mapped, so I know the values exist)
$(this).attr('name') gives me the name 'category' no matter which check box I click. That is the name of the check box component that the array is mapped to.
$(this).prop('checked') gives me undefined.
$(this).attr('checked') gives me undefined.
$(this).prop('id') gives me undefined.
$(this).attr('id') gives me undefined.
$(this).is(':checked') gives me "false" no matter which check box I click, and no matter if it is checked or not.
Hello! So you add event on item, not entire group. If so this will point on item. Try the following way to see if it's checked pre$(this).find("input").is(":checked")/preto get value pre$(this).find("input").val()/pre
