The HTMLElement.title property represents the title of the element, the text usually displayed in a 'tool tip' popup when the mouse is over the displayed node.
If a node does not have a title attribute, then the default action is to inherit it from its parent node, which in turn may inherit it from its parent node, etc.
<div title="CoolTip"> <div title="">mouse over here will popup "CoolTip"</div> <div title=" ">mouse over here will popup nothing"</div> </div>
var str = element.title;element.title = str;
button1.title = "click to refresh";
