Hello, Praveena,

Please help us to help you.  We need to see your code, especially whatever function is defined that contains that line number you mentioned in the error message.

V/r,

^_^

Hi, Praveena,

It never even occurred to me to point out that a CF error will give the actual line number of _code_ that generated the error; but JavaScript is a client-side script, so it will provide the line number of the HTML that is generated by the server, not the line number of the code that produced it.  My apologies - I should have been more thorough in formulating my request.

If you could, please, do a "View Source" on the HTML after the JavaScript error alert is dismissed, and provide the JavaScript function or code that is causing the issue.

V/r,

^_^

I'm not versed in any languages other than English, so translating your code comments will be difficult, but I think I'll still be able to follow your logic.  I'll see what I can find.

V/r,

^_^

UPDATE:  One thing that is kind of throwing me off balance is you reference an array called "arrayPista", but I do not see arrayPista being defined or initialized prior to it.  I am assuming that arrayPista is an array created outside of this function.

praveenaa11254626,

As far as I can tell, there are three objects that are not being defined within this function (arrayPista, arrayRestricciones, arrayUsuariosRestriccion).  If they are being defined outside of this function, you need to make them available to this function.

If they are being defined inside another function, you need to var the container/variable at the top of the script, first.  If they are being defined globally, check if you are preceding the variable name with var.  Your line 96 is trying to create an array from an array of arrays (I think), but the array of arrays is not defined (or not globally available) at that point.

HTH,

^_^

  arrayUsuariosRestriccion=arrayRestricciones[indiceDia].split('|');

Does arrayRestricciones[indiceDia] exist and is it a string? Test using alert().
