[SOLVED] passing a variable

Hi,

 

I have added in a drag and drop function from a tutorial and it works well. The problem I am having is that I need my variable g_objName to be associated with dragobj. Has anyone any ideas?

 

function showObject (){
if (request.readyState == 4) {
var returned = request.responseText;
var splitResult = returned.split(" ");
var h = splitResult[0];
var w = splitResult[1];
h = h/5;
w = w/5;

cv = document.getElementById("canvas");
var newObject = document.createElement('div');
newObject.Class = g_objName;
newObject.id = "newObject";
newObject.innerHTML = g_objName;
newObject.style.height = h;
newObject.style.width = w;
newObject.onmousedown=function(){grab(this);}	
cv.appendChild(newObject);
}

function grab(context)
{
  document.onmousedown = falsefunc; // in NS this prevents cascading of events, thus disabling text selection
  dragobj = context;
  dragobj.style.zIndex = 10; // move it to the top
  document.onmousemove = drag;
  document.onmouseup = drop;
  grabx = mousex;
  graby = mousey;
  elex = orix = dragobj.offsetLeft;
  eley = oriy = dragobj.offsetTop;
  update();
}

Hmm... wouldn't g_objName already be available to you in grab()?  You're assigning the function to the onmousedown event handler of newObject.  Since g_objName is a property of newObject, it should be available inside of grab() as this.g_objName.
