Sys.UI.DomElement getVisible Method
Gets a value that indicates whether a DOM element is currently visible on the Web page. This member is static and can be invoked without creating an instance of the class.
var v = Sys.UI.DomElement.getVisible(element);
Parameters
Term |
Definition |
|---|---|
element |
The target DOM element. |
Returns
true if element is visible on the Web page; otherwise, false
Remarks
Use the getVisible method to determine whether a DOM element is currently visible on the Web page. Calling the getVisible method differs from reading the DOM element's visibility property directly because the getVisible method accounts for visibility modes applied with the Sys.UI.DomElement.setVisibilityMode method.
For information about how to set the layout characteristics of hidden DOM elements, see Sys.UI.DomElement setVisibilityMode Method.
Example
The following example shows how to use the getVisible method. The code toggles the visibility of an element based on its current setting.
var anElement = $get("Label1");
if (Sys.UI.DomElement.getVisible(anElement)){
Sys.UI.DomElement.setVisible(anElement, false);
}
else{
Sys.UI.DomElement.setVisible(anElement, true);
}
