WMLScript How to
How to call a WMLScript from a WML page
WMLScripts are not embedded in WML pages.
A WML page only
contains references to script URLs.
In the example below, if you select the go label, the external script will
direct you to http://www.w3schools.com/wap.wml:
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="no1" title="Go to URL">
<do type="options" label="Go">
<go href="check.wmls#go_url('W3Schools')"/>
</do>
</card>
</wml> |
The red line above contains a reference to a WMLScript. The script is in a
file called check.wmls, and the name of the function is go_url.
Here is the WML page called check.wmls:
extern function go_url(url)
{
if (url=="W3Schools")
{
WMLBrowser.go("http://www.w3schools.com/wap.wml")
}
} |
Note that the function is using the extern keyword.
When using this keyword the function can be called by other functions or WML events
outside the .wmls file. To keep a function private, drop the extern keyword.
