MsgBox / Alert won't show

[Reynaldi]

I have a grid with some validation, which will show error message as alert / A5.msgbox as an function_name = "alert('test');". When I debug it, the error message was triggered, but nothing shows up, and sometimes I got an error. When I asked around, I was told that they encounter the same thing thinking the alert / A5.msgbox won't show up if there's too many if containing function_name = "alert('test');", I don't believe that was the case but I don't know what's wrong. I'll attach part of the code and a picture to help understand what I meant.

function saveNG as c (e as p)

dim filter as c
filter = e.checkboxfilter

if filter = "" then
 message = "alert('No Data Selected');"
else
 <some code>
 if lastNG != totalChecked then
		message = "alert('Quantity doesn't match');"
	else
                <some code>
                message = "alert('Saved');"
	end if
end if

saveNG = message
end function

the code itself works, but just won't show the alert for the "alert('Quantity doesn't match');", the "No data selected" and "saved" alert works fine

here's the error message when i triggered "alert('Quantity doesn't match');", I believe there's no syntax error and it says error at line 246 but my code only has 139 line

Re: MsgBox / Alert won't show

Either escape the single quote in "doesn't" or use "does not. To ensure stuff going back to the client is ok, you can use js_escape...

function saveNG as c (e as p)

dim message as c
dim lastNG as n = 1

if lastNG = 1 then
	message = "Quantity doesn't match"
else
	message = "Saved"
end if

saveNG = "alert('" + js_escape(message) + "');"

end function

js_escape works like a charm! Thank you
