JavaScript function doesn't work

The function:
	function enableBoxesSold(whichSelect,whichBox,overage,shortage){

Open in new window

doesn't work when called with:
echo "<SELECT size=1 id='contractor1' name='contractor1' onblur='enableBoxesSold('contractor1','BoxesSold1','contractor1o','contractor1s');updateBoxes(1);' tabindex=1>";

Open in new window

It does work if I remove all parameters from both the function and the onblur event.  If I add in one parameter it fails.

This php page has over 2,000 lines and the error I see, using Chrome dev tools, is:

Uncaught SyntaxError: Unexpected token } at line 2145

Line 2145 is no where near this function or select element.

Any thought?

Something in your PHP code is not bracketed properly.  I run into this when I'm editing a page at times.  The first thing I would try is commenting out the '}' on line 2145 and see what happens.
Dave BaldwinFixer of ProblemsCommented:
In your 'onblur' statement, the variables for the enableBoxesSold() function must be defined in the HTML page before you reach that line.  Note that those are JavaScript variables, not PHP variables.

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Hmmm so you mean stick something like
	var whichSelect;
	var whichBox;
	var overage;
	var shortage;

in the code?  I never heard of that being an issue.
Sheldon LivingstonConsultantAuthor Commented:
The issue was using ' instead of ".  I had to use \"
Dave BaldwinFixer of ProblemsCommented:
Is it fixed now?  When you pass values (variables) to a function, they do have to be defined first.  Otherwise you are passing NULL or undefined value which is usually an error.
Julian HansenCommented:
As you have correctly deduced the problem is you are outputting a string which has single quotes enclosed in single quotes - which is going to cause the browser to throw the error you are seeing.
So instead of this
echo "<SELECT size=1 id='contractor1' name='contractor1' onblur='enableBoxesSold('contractor1','BoxesSold1','contractor1o','contractor1s');updateBoxes(1);' tabindex=1>";

Open in new window

I would rather use heredoc to output lines like the above.
Mixing double and single quotes in a quoted string is always a pain. Heredoc gets around this problem by allowing both " ' and $variable in the string.

In your case it would be
echo <<< HTML
<select size=1 id="contractor1" name="contractor1" onblur="enableBoxesSold('contractor1','BoxesSold1','contractor1o','contractor1s');updateBoxes(1);" tabindex=1>

Open in new window

Note with HEREDOC the closing tag (in this case HTML) must be flush against the left margin with no spaces after the ';'
