• Download source - 10.02 KB

Introduction

This article will show you how to make a web service call using only HTML markup and JavaScript.

Background

This article is based on JavaScript SOAP Client on http://www.codeplex.com/JavaScriptSoapClient.

Using the Code

Just copy and and change the scripts and markups. You can see a JavaScript example below.

//Calls Hello World Web Method.
var url = document.location.href.replace("default.htm", "webservicedemo.asmx");
	
// DEMO 1
function HelloWorld()
{
	var pl = new SOAPClientParameters();
	SOAPClient.invoke(url, "HelloWorld", pl, true, HelloWorld_callBack);
}
function HelloWorld_callBack(r)
{
	alert(r);
}
// End of script.		

That's all guys.

Points of Interest

I already knew how to make a web service call from JavaScript using webservice.htc. I could not make these calls on browsers other than Internet Explorer. So I searched and found this method. It is so simple to use. Add soapclient.js to your project and some code like the above. Then call it with something like button, etc.
