Hi everyone!

I want to add an onclick event handler on a field , so that when clicked (or focus) to hide an element.

Here is my code:

function setOnFocus()
{
    var preferredResource = document.getElementById("ral_preferredresource");
	
	if (preferredResource){
		alert("on click");
		preferredResource.attachEvent("onclick", hideFormAssistant);
	}
	
}



function hideFormAssistant()
{
  alert("in hideformassistant");
  document.getElementById('tdRelatedInformationPane').style.display = 'none';
}

Any ideas why it doesn't work? It errors on this line

preferredResource.attachEvent("onclick", hideFormAssistant);

Not sure if this can be done with supported way. Unfortunately the supported way most of the times is just not enough. But yes it is best practice to use it when you can!

Shak,

You use "Dom manipulations" that are not supported - that's why your code doesn't work as it expected ;) . I would suggest to find supported way to resolve your scenario.

Figured it out. Had to use addEventListener
