Question

For one reason or other ( I’m not going to go into why here) I need to use javascript to get the values of 12 hidden input fields and set a variable for each value.

I am not sure what the best approach for this would be. I’d like to be able to get the values and if they are not created i.e. the input fields are not there then id like to generate an error.

Would using a try / catch be good for this or should I simply be using typeof to check the variables have been created?

would putting them in an array as well so i can loop through to check their existance be a good idea?

thanks

This is the easy way of doing it. try-catch is rather heavy. Also, where would you throw the error to? Instead of unwinding your flow on error, collect your errors into a well structured response. That way if your first one is missing, but the other X are not, then you still get some work done.

if ( typeof( something ) !== "undefined" ) { doStuff(); }

Otherwise, I’d need more information to help you with your question.
