One Custom Field show another custom field based on answer?

[Bryan Trummer - ReleaseTEAM]

I would like to have in my resolution screen a custom field with two radio buttons (yes,no). If yes is selected another free text field will appear, if no is selected nothing will happen. Is this something that can be done in JIRA 4.1? Any help is appreciated!

add this script on free text field description in field configuration

<script type="text/javascript">
var radioButtonName = document.getElementsByName('customfield_10570');
var textFieldRow = document.getElementById('customfield_10571FieldArea');
var textField = document.getElementById('customfield_10571');
textFieldRow.style.display = 'none';
for(var x = 0; x < radioButtonName.length; x ++){
radioButtonName[x].onclick=function(){showHideField();}; 
}
function showHideField(){
var checkedId = "";
for (var x = 0; x < radioButtonName.length; x ++){
if(radioButtonName[x].checked == true)
checkedId = radioButtonName[x].value;
        }
if( checkedId == "Yes" ){ 
textFieldRow.style.display = '';
}else {
textField.value = '';
textFieldRow.style.display = 'none';
}
}
showHideField();
</script>

Note: change custom fields as per your instance

Do I need to have this script in the radio button or the text field when yes is selected

[Bryan Trummer - ReleaseTEAM]

I do appreciate any and all help as I am fairly new to a lot of this.

So my radio button ID is 10172 and the free text field that I want to appear if the Yes radio button selected is 10173. I thought I plugged it in correctly but here is the code I have the in the radio button field description.

<script type="text/javascript">

var radioButtonName = document.getElementsByName('customfield_10172');

var textFieldRow = document.getElementById('customfield_10173FieldArea');

var textField = document.getElementById('customfield_10173');

textFieldRow.style.display = 'none';

for(var x = 0; x < radioButtonName.length; x ++){

radioButtonName[x].onclick=function(){showHideField();};

}

function showHideField(){

var checkedId = "";

for (var x = 0; x < radioButtonName.length; x ++){

if(radioButtonName[x].checked == true)

checkedId = radioButtonName[x].value;

}

if( checkedId == "Yes" ){

textFieldRow.style.display = '';

}else {

textField.value = '';

textFieldRow.style.display = 'none';

}

}

showHideField();

</script>

you have to textarea field description(which is last in the form)

don't forgot to add in field description of fieldconfiguration

You might want to add a Javascript into custom field or the field configuration to manipulate the DOM. Google around, there are examples.
