asked on Concatenated String Works on my SharePoint Online Site but Not on Another Site
I have built a JavaScript function which reads a JSON file and from that file it creates a string which represents the JSON array as a DIV structure. This function works as expected on my Site, but stops concatenating when run on another. The JSON file is the same and so is the read and concatenation routine.
After about the 9th iteration through the array, I examine the accumulating string in the debug tools console and even though the loop continues, the accumulating string stops acquiring additional substrings.
Is there some kind of resource limit that could be doing this in one site environment and not mine?

can you please show us the code for how you're accumulating the string?

There shouldn't be anything that prevents "out" from accumulating. It's just a string. My best guess is that one or more conditions are not being met. To test this theory, you could put a matching "else" clause for every if statement and accumulate a test message to out in that condition. For example, you check for this condition a couple of times, but don't specify what should happen when it isn't met:
if (subMenuDivOpen==true && itemDivOpen==true)
{
//..stuff you already have
}
else
{
out+= "Oops, condition is false";
}

I put a breakpoint before the assignment. I look at the value of out in the assignment. I then go back to the debugged code and copy the substring that is about to be assigned to out and it is a full as expected value.
After I execute the out+= "some stuff" statement. I go back to the console to view the out variable. It has all the values up to part of the "some stuff" value.
Again, the odd thing to note is that this works fine on one Site Collection and fails on another. Doesn't sound like code or data to me.

Hi,
I discovered what it is and it has nothing to do with the sites and their configuration. It's IE. When I run the same javascript through Chrome, I see the full string. There must be a size limitation that IE developer tools will display.

Well, that makes sense that it wasn't the code.
