I was wondering if their is an easier way to do this; I want to select a number one through twelve from a dropdown and display that many textboxes and their labels this is how im setting it up.

<script>
$(document).ready(function() {
        $('#one').hide();
        $('#two').hide();
        $('#three').hide();
        $('#four').hide();
        $('#five').hide();
        $('#six').hide();
        $('#seven').hide();
        $('#eight').hide();
        $('#nine').hide();
        $('#ten').hide();
        $('#eleven').hide();
        $('#twelve').hide();
    $('#quantity').change(function() {
        dropdown = $('#quantity').val(); 
        if (dropdown == '1')
        {
           $('#one').show();
        }
        if (dropdown == '2')
        {
         $('#one').show();
         $('#two').show();
        }
        if (dropdown == '3')
        {
         $('#one').show();
         $('#two').show();
         $('#three').show();
        }
        if (dropdown == '4')
        {
         $('#one').show();
         $('#two').show();
         $('#three').show();
         $('#four').show();
        }
    });
});

How about using a loop?

JorgeM 958 Problem Solver

definately the loop is the way to go.... to give you a hint... you may want to re-ID those li elements and give new IDs such as li1, li2, li3, etc...

there are different methods to approach this problem, but the various options will all use some form of a loop to make this more effecient. What if you had 100 options? This manual show/hide isnt scalable.

Ok brandon66, one way to approach this is to first hide all of the textboxes. you can do this by adding a class and setting this class to display:none;

In the loop, you simply show each textbox by ID. since you are using a variable in your loop, you can use that variable in your block that shows the textbox.

here is an example that you can look at and see a working model using a loop to show textboxes based on the dropdown value.

I was thinking that but im not too familiar with javascript/jquery; learning though.

brandon66 0 Expert in Progress · Answer 2 · 2013-08-16T21:41:12+00:00

Would something like this work

While (Selected).val() <> 0{



}

or

do
   {



   }
 while ((#selected) > 0);

iamthwee · Answer 3 · 2013-08-16T22:23:20+00:00

What you need to do is reference your ids as actual numbers.

For example id='1', id='2'

This will make it easy to loop and select any forseen number.

so this is what I have so far might need a little schooling with the javascript loops to do this

does anyone have an idea on how to loop this?

I don't think you need to loop. I haven't had time to test but this page looks like you could adapt JorgeM's code and simply select the textboxes.
