OnBeginLoad Trigger

onbeginload="Function(); Function2(); ..."

• The trigger can be used to execute one or more functions.
  
• Instead of a function, you can specify the URL of a page to open.
  

<xml id="toolbar">
<toolbar caption="OnBeginLoad Example">
<control type="toolbar">
<button
caption="Idle"
onload="SetCaption(this,'Loaded %URL%'); SetIcon(this,'http://www.toolbarbrowser.com/img/smiley.io')"
onbeginload="SetCaption(this,'Loading...')">

</button>
</control>
</toolbar>
</xml>



In the above example, when a page starts to load, the onbeginload trigger changes the caption to "Loading...".
After the page is loaded, the onload trigger executes two functions. The first changes the caption to display the URL of the loaded page and the second changes the icon.
