hide fied based on the selection of other fields

[samhans]

Hai steve and friends;

I am trying to hide some of my fields upon selection of select item in some other field. i.e

suppose i have a field consumable type if some one select paper he should see only type of paper after that, if he select cartridge then he should see the printer model and
cartridge number field.

i have tried using java but not able to do it. Please some body guide through the piece of code to do this.

thanks in advance.

Hi Samhans,
You have to use javascript (http://xataface.com/documentation/how-to/custom_javascripts) a bit like this :

Code: Select all

function getSelectValue(selectId)
   var selectElmt = document.getElementById(selectId);
   return selectElmt.options[selectElmt.selectedIndex].value;
}
function hide (selectId){
if (getSelectValue(selectId)=='this'){
myfield.setAttribute("style","display:none;");
}
}


In your fields.ini, you add :

Code: Select all

widget:atts:onchange="getSelectValue('myselectlist')"


Cheers

Jean

Samhans,
In fact you want to build a dynamic select box like here ? http://xataface.com/wiki/Dynamic_select_boxes
