how can i make a dynamic text area?

hello ! i need to do this

text area 1 | input by user
text area 2 | dynamic text area
text area 3 | dynamic text area2


in the page we well see this

text area 1 = 2 <--- input by user

text area 2 = 4 <---[ 2+(text area 1) ] the text box do automatic do the equation and show me the resuly (in this case its "4")

text area 3 = 40 <--- [text area 2 + 10 ] <--- the same of text area 2 but gettin the information of text area 2 and multiply by 10


The idea is to automation to confirm results before submitting the form, in which case the user just enter the number "2" in the first text box and the second box will automatically add 2, and the third will multiply 10 to second box .. and obviously shows me to confirm the data before pressing the submit botton


thank you very much

Hi hilas,

You can do this with a JavaScript code snippet in the Load JS action. It will be something like this:

window.addEvent('domready', function() {
  $('input_text_1').addEvent('change', function() {
    $('input_text_2') = $('input_text_1').value + 2;
    $('input_text_3') = $('input_text_2').value * 10;
  });
});

Not tested and may need debugging.

Note that 'input_text_1' is the ID of the form element.

Hello GreyHead

Well, thank you very much for the reply, the problem is not so much about "how to" this code where I have it set? , And secondly it will be to form which I have several boxes of income such as name, surname, email .. and also the summation and multiplication box, then where I have to put this code and do not need anything else? or is it just that code and nothing else?

Hi Hilas,

Which version of ChronoForms are you using? You can find the version from Site Admin | Extensions | Install/Uninstall | Components in Joomla! 1.5 or Site Admin | Extensions | Extension Manager | Manage in Joomla! 1.6.

i'm usin Joomla 1.5 with chrono forms v4 and chrono connectivity (wich dont work)

but i think that i need to change to joomla 1.5 becouse i need the chrono connectivity . there is some chat for chat with you ? plz

Hi hilas,

In ChronoForms v4 you can use the Load JS action to add JavaScript to your form.

As I said in the other post you can add filters with the ChronoForms v4 DB Load Multi Record action, you don't need ChronoConnectivity.

I suggest you focus on getting a basic form working, then add the calculations and filters later.
