jQuery - For Loop question

[Nakataa Kokuyo]

Good day,

I have an array('checkComponents ') which holding list of textbox input id, and i want to iterate it to get the user value that have been type but seem i didn't get my luck on it.

var checkComponents = ["client_name","client_ic","client_age","client_address1","client_contact"];
for(var index in checkComponents){
                    alert('value of '+index + '='+$(checkComponents[index]).value);                   
                }

question : how to used jQuery to get user input value from an array that holding input component id?

Appreciated your help on this !

I'd use jQuery.map().

Thanks Bear and that's a good function, here is what i try but i get the value of "undefine"

 $.map(checkComponents, function(value, index){
                   //alert('array'+index + '='+value) ;
                   var inputValue = $(value).val();
                   alert('input value='+inputValue);
                });

You're not forming the selector correctly from the id values.

Also, alert is a dinosaur. At least open a JavaScript console and use console.log().

Thanks Bear for the clue

one extra question Bear, if we using console.log() , is it compatible to all browser and it won't caused any exception ?

It's not something that you'd leave in your code, just like you wouldn't leave in any debug alerts.

All modern browsers support some sort of JavaScript console, but a reference to console can fail if it's disabled (which it will be for most users).

[Nakataa Kokuyo]

Thanks again Bear, is there a chance to turn on the console automatically if it was off (probably from code call) ? the debug message is somehow useful when complicated JS function applied.

[Bear Bibeault]

No.

Would you really want the JavaScript console to pop open on a user whenever they visit your page?

make sense Bear , thanks again !
