Global variable showing as undefined

Hello
I am trying to declare a global javascript variable that I can use anywhere on the page. However, when I click on the button to open the action window it shows as 'undefined'.

I declared the variable in the head section like thus:
var ref;

Open in new window

I have posted my code and would be grteful if someone could help me correct this. Many thanks

// get the clicked row's data and initialize the input fields.
var dataRecord = $("#jqxgrid").jqxGrid('getrowdata', acteditrow);
activity = dataRecord.activity;
ref = dataRecord.item;
alert(ref); <--- THIS WORKS

if (activity == "New Intake") {
  $("#rack").val(dataRecord.rack);
  $("#row").val(dataRecord.row);
  $("#column").val(dataRecord.column);
  $("#bay").val(dataRecord.bay);
  $("#size").val(dataRecord.size);
  document.getElementById('destdate').value = dataRecord.destdate;

  // show the popup window.
  $("#actionWindow").jqxWindow('show');
}

Open in new window

Not sure if it can be done this way...never seen such code.

An alternative would be:

<div>You are actioning item: <div id='refContents'></div></div>

Open in new window


then in your javaScript code above add something as follows:

var refC = document.getElementById("refContents");
refC.innerText = ref;

Open in new window


Let me try to discourage you to use variable names like ref, which could have some meaning any language.
