 Hi,

   I have a checkbox on HTML page. I have added some java script and css to
 style the checkbox. To handle this checkbox in wicket  i have added
 AjaxCheckBox. But when i click on checkbox it is not calling OnUpdate()
 method of AjaxCheck box.

 This is working fine when i remove the styling and javascript for checkbox.

what is the javascript ? show us


 Could you please help me.

Thanks for your quick response. Here is the Java Script file i am using to
style the ckeckbox.


//global variables that can be used by ALL the function son this page.
var inputs;
var imgFalse = 'images/false.png';
var imgTrue = 'images/true.png';

//this function runs when the page is loaded, put all your other onload
stuff in here too.
function init() {

replaceChecks();
}

function replaceChecks() {

//get all the input fields on the page
inputs = document.getElementsByTagName('input');

//cycle trough the input fields
for(var i=0; i  inputs.length; i++) {

//check if the input is a checkbox
if(inputs[i].getAttribute('type') == 'checkbox') {

//create a new image
var img = document.createElement('img');

//check if the checkbox is checked
if(inputs[i].checked) {
img.src = imgTrue;
} else {
img.src = imgFalse;
}

//set image ID and onclick action
img.id = 'checkImage'+i;
//set image 
img.onclick = new Function('checkChange('+i+')');
//place image in front of the checkbox
inputs[i].parentNode.insertBefore(img, inputs[i]);

//hide the checkbox
inputs[i].style.display='none';
}
}
}

//change the checkbox status and the replacement image
function checkChange(i) {

if(inputs[i].checked) {
inputs[i].checked = '';
document.getElementById('checkImage'+i).src=imgFalse;
} else {
inputs[i].checked = 'checked';
document.getElementById('checkImage'+i).src=imgTrue;
}
}

window.onload = init;

use normal function here. Function is much slower


                        //place image in front of the checkbox
                        inputs[i].parentNode.insertBefore(img, inputs[i]);

                        //hide the checkbox
                        inputs[i].style.display='none';

try with
visibility: hidden

display:none form elements are not submitted by the browser

                }
        }
 }

 //change the checkbox status and the replacement image
 function checkChange(i) {

        if(inputs[i].checked) {
                inputs[i].checked = '';
                document.getElementById('checkImage'+i).src=imgFalse;
        } else {
                inputs[i].checked = 'checked';
                document.getElementById('checkImage'+i).src=imgTrue;
        }
 }

 window.onload = init;
