Calling WebServices using Javascript
Calling WebServices using Javascript
If you are using Microsoft IE 5 or later, you can use the behavior/HTML-Component "WebService" to access a Web service. The "WebService" behavior communicates with Web services over HTTP using Simple Object Access Protocol (SOAP).
To use the "WebService" behavior, you must attach it to an element using the STYLE attribute, as follows:
STYLE="behavior:url(webservice.htc)">
A complete example taken from the Microsoft Web site is as follows:
Enter a Value
style="behavior:url(webservice.htc)"
onresult="onmyresult();">
