Hi all,
I've setted this Javascript function in Exit event of my Numeric Field:

if (this.rawValue.length != 6)
{
xfa.host.messageBox("Dossier must be composed of 6 numbers", "Dossier Titoli error", 3);
this.validate.nullTest="error";
this.mandatory="error";
false;
}

but this message appears also when the user input exactly 6 numbers.

What's the problem in this function?

Thanks in advance.

Luigi

I may be wrong, but with numeric field, you are not able to find the length of item as it is not string. You should check on the interval of the integer from 99999 till 1000000 to get you 6 digits number.

In FormCalc you can use the "Len()" function to get the length of a field's value.

// raw valuexfa.host.messageBox(Concat("rawValue: ", $.rawValue, " Length: ", Len($.rawValue) ) )// formatted valuexfa.host.messageBox(Concat("formattedValue: ", $.formattedValue, " Lenght: ", Len($.formattedValue) ) )

This is a LiveCycle Designer forum and FormCalc works differently then JavaScript. One of these differences in that FormCalc uses a function to get the length of a item and is not accessing the length property like JavaScript. So LiveCycle Designer can test for a numeric value and convert it to a string before obtaining the length property. One could even write a JavaScript function to obatin the lenght of any value, it would just need to create a string using the 'toString()' method before computing the length of the value.
