Checkbox set value

Hi can anyone please tell me how to set the value of a checkbox item, from Javascript ??...

DCT has the following entry for the checkbox.

Display Image Only

I tried setOptions(), but it works only if the value set is "true", but if we want to change the value, to suppose "false", setOptions() doesnt work !!... The code that works is :

var optionArray = IWDatacapture.getItem("/display_img_only").getOptions(); optionArray[0].value = "true";
optionArray[0].selected =false; IWDatacapture.getItem("/display_img_only").setOptions(optionArray);

but,

optionArray[0].value = "false";
optionArray[0].selected =false;

Doesnt work !!...
Is there a value to set the value returned by the checkbox ??.

Appreciate any help !!..

var areaOptions = Item.getOptions();
areaOptions[0].selected = false;
Item.setOptions(areaOptions);

or to toggle on/off

 function toggleCheckbox() {
  chbxItem = IWDatacapture.getItem("/page/your/item");
  var areaOptions = chbxItem.getOptions();
  var chekVal = chbxItem.getValue();
  if (chekVal != '') {
   areaOptions[0].selected = false;
  } else {
   areaOptions[0].selected = true;
  }
  chbxItem.setOptions(areaOptions);
 }

I was in a hurry to get this working. Does anyone have any good ideas on how to make this more compact? This code works, it just seems a little clunky to me...

I haven't tested it - but you might be able to do something like:

function toggleCheckbox(chbxItem) {
    var options = chbxItem.getOptions();
    var chekVal = chbxItem.getValue();
    options[0].selected = !options[0].selected;
    chbxItem.setOptions(options);
}

Slick.
Works perfectly, thank you

I'm glad it worked - looking at it again, you could probably get rid of the line indicated below as that variable isn't used here

function toggleCheckbox(chbxItem) {
    var options = chbxItem.getOptions();
var chekVal = chbxItem.getValue();
    options[0].selected = !options[0].selected;
    chbxItem.setOptions(options);
}

- or you need to modify the code like:

function toggleCheckbox(chbxItem) {
    var options = chbxItem.getOptions();
    var chekVal = chbxItem.getValue();
    options[checkVal].selected = !options[checkVal].selected;
    chbxItem.setOptions(options);
}
