Need to hide/show a textfield based on the value of the check box using Javascript?

[IT Support]

Hey guys,

Got a little problem/question:

I tried to implement the script from https://answers.atlassian.com/questions/158035/need-to-hide-show-a-textfield-based-on-the-value-of-the-check-box-using-javascript, but it doesn't seem to be working for me.

I've got the following fields:

Forward Email (customfield_13428) - Multicheckbox (Yes is selectedvalue=13924)

Email to forward to (customfield_13429) - Text Field < 255 char

Unsure what I'm doing wrong here?

<script type="text/javascript">
jQuery(document).ready(function($) {
JIRA.bind(JIRA.Events.NEW_CONTENT_ADDED, function (e, context) {
callHideShowFunction();
});
callHideShowFunction();
function callHideShowFunction(){
showHideReason();
$("#customfield_13428").closest('div.field-group').hide();
$('input:radio[name=customfield_13924]').click(function() {
showHideReason();
});
//the following event will work on only create screen
$('#create-issue-submit, #issue-create-submit').click(function() {
var emergencyImpl=$('input[name=customfield_13924]:checked + label').text();
var reasonValue=$("#customfield_13428").val();
if( emergencyImpl =='Yes' && ( reasonValue == '' || reasonValue == ' ') ){
alert("Please enter Reason");
return false;
}
});


}
function showHideReason(){
var emergencyImpl=$('input[name=customfield_13924]:checked + label').text();
if( emergencyImpl == "Yes" ){
$("#customfield_13924").closest('div.field-group').show();
}else {
$('#customfield_13428').val('');
$("#customfield_13428").closest('div.field-group').hide();
}

}
});
</script>

Any help would be fantastic.

Thank you!

try with this script

<script type="text/javascript">  
jQuery(document).ready(function($) {
    JIRA.bind(JIRA.Events.NEW_CONTENT_ADDED, function (e,context) {
        checkBoxFunction();
    });
    checkBoxFunction();
     
function checkBoxFunction(){                
            showorhidefields(); 
            //assume 4 checkbox there with name  'customfield_11705'
        $("#customfield_11705-1,#customfield_11705-2").click(function() {
            showorhidefields(); 
        }); 
     
         
    }
function showorhidefields(){
    alert("inside function");
    var checkedCheckboxes = $("input:checkbox[name=customfield_11705]:checked");        
            $("#customfield_11704").closest('div.field-group').hide();      
        checkedCheckboxes.each(function () {
                var selVal=$(this).next("label").text();
                alert("selVal: "+selVal);               
                if(selVal == 'Yes'){                    
                    $("#customfield_11704").closest('div.field-group').show();  
                }else {
                    $('#customfield_11704').val('');
                    $("#customfield_11704").closest('div.field-group').hide();
                }               
                 
            });
        }   
         
 
    });
</script>

for check boxes you have to use the check box id to get value

var fieldusedforchage = document.getElementById('customfield_13924-1')

if(fieldusedforchage .checked)

{

field.style.display ='';

}
