Question

I have the following HTML:

<input type='text' name='af_student_startdate' id='start115'>
<input type='text' name='af_student_startdate' id='start116'>

And the following jQuery

$('#save').click(function() {

    var values = {};

    $('input[name="af_student_startdate"]').each(function(n, el){
        values [ $(el).attr('id') ] = $(el).val();
    });

    $.ajax( {
    type : 'POST',
    url : '/update.php',
    data : {af_student_startdate: values}
  });

})

This will POST for example:

af_student_startdate[start115]  2012-09-01
af_student_startdate[start116]  2012-09-25

How can I remove the text “start” so that I only POST the INT values to update.php?

Answer 1

Try this:

values [ $(el).attr('id').match(/\d+/g) ] = $(el).val();

You can also code:

values [ this.id.match(/\d+/g) ] = this.value;

Which is faster and better than creating unnecessary jQuery objects.
