Question

My “stack” is totally overflow, so I need a help 🙂

I trying to get all values from FORM and save them to associative array. Here is a code:

var dat = [];
$('form[name=' + form.name + '] input[name], form[name=' + form.name + '] select[name], form[name=' + form.name + '] textarea[name]').each(function(i,el) {
   dat[$(this).attr('name')] = $(this).val();
});

I am waiting for all values become in dat after this piece of code, but it looks like dat is internal variable of .each() lambda function, so it is unavailable after .each() is completed.

How to return resulting dat[] from the cycle ?

Answer 1

Try this

function() getFormData(){
    var dat = {};

    $('form[name=' + form.name + ']').find('input[name], select[name], textarea[name]').each(function(i,el) {
       dat[$(this).attr('name')] = $(this).val();
    });
    return dat;
}

This function will return a json object containing all the form elements name/value pair specified in the selector.
