IfMatch() Function

IfMatch(string,match,action)

Parameter:	Description:
string	string to match. Can include variables.
match	sub-string to match. Can include variables.
action	action to take if a positive match is made. This can include one or more functions separate by a semicolon.
else	alternate action to take if no match is made. This can include one or more functions separate by a semicolon.

• The IfExactMatch() and IfMatch() functions are used to provide basic logic.
  
• The string matching is not case sensitive.
  
• The else parameter is optional and does not need to be specified.
  
• The else parameter is ignored in Toolbar Browser versions prior to 2.3.1
  

In the following example, the IfMatch() function is used to place a notice on the toolbar if a user visits a page on the trellian.com domain.



<xml id="toolbar">
<toolbar caption="IfMatch() Example">
<control type="toolbar">
<button

caption="..."
id="button1"
action="http://www.trellian.com"
onload="IfMatch($URL,'trellian.com',SetCaption(button1,'Latest Release!!!'); SetParam(button1, "action",'http://www.trellian.com/download.com'))">

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




When ever a new page is loaded, the onload= event trigger executes the IfMatch() function. If the URL of the page matches the specified URL, in this case 'trellian.com', the button caption is changed. The second function SetParam() changes the button's default action.

Note the use of the $URL system variable to compare the currently loaded page.

Requires ToolbarBrowser version 2.3.1 or later.
In versions prior to 2.3.1, the else parameter is ignored.
