Hello!
This function has not closing bracket:
function setElementVisibility(elementToSet, showItSwitch, keepPlacementSwitch){

Here's the right way:

function setElementVisibility(elementToSet, showItSwitch, keepPlacementSwitch){<br />
 if (showItSwitch) {<br />
   elementToSet.style.display = "inline";<br />
   elementToSet.style.visibility = "visible";<br />
 } else {<br />
     elementToSet.style.display = "inline";<br />
     elementToSet.style.visibility = "hidden";<br />
  }<br />
}

Please pay attention to the last bracket.
To get the value of the cleck-box, you will have to inject its ID to javascript code: here's how:
setElementVisibility(document.getElementById("a"), false, document.getElementById('<%= TextBox1.ClientID %>').value);

Regards

This will do good i think

C#

function setElementVisibility(elementToSet, showItSwitch, keepPlacementSwitch)
{
     if (showItSwitch) 
     {
       elementToSet.style.display = "inline";
       elementToSet.style.visibility = "visible";
     }
 else
    {
       elementToSet.style.display = "inline";
       elementToSet.style.visibility = "hidden";
     }
}
