using prototype: 
<SCRIPT LANGUAGE="JavaScript"><!--
// define the myString object
function myString(value) {
this.value = value;
}
// define the textfunc() method
function testfunc(value) {
this.value = value;
}
// set the prototype
myString.prototype.testfunc = testfunc;
// create an instance of a myString object
var mytext = new myString('this is a test');
// alert the value propert of the mytext myString object
alert(mytext.value)
// use the myString testfunc() method
mytext.testfunc('teststring');
// alert the value propert of the mytext myString object
alert(mytext.value)
//--></SCRIPT>
 
Or by adding a method to the object: 
<SCRIPT LANGUAGE="JavaScript"><!--
// define the myString object
function myString(value) {
this.value = value;
this.testfunc = testfunc;
}
// define the textfunc() method
function testfunc(value) {
this.value = value;
}
// create an instance of a myString object
var mytext = new myString('this is a test');
// alert the value propert of the mytext myString object
alert(mytext.value)
// use the myString testfunc() method
mytext.testfunc('teststring');
// alert the value propert of the mytext myString object
alert(mytext.value)
//--></SCRIPT>
