1、Using Javascript eval Method。 2、using a veriables save object "this" reference. 3、in innerHTML, we can using String to pass the prototype Method。
e.g.
<SCRIPT LANGUAGE="JavaScript"> <!-- function myClass(instanceName) { this.instanceName = instanceName; this.instance = this; return this; }; myClass.prototype.toAlert=function() { eval(this.instanceName).callback(); // the first method to call prototype function. this.instance.callback(); // the second method to call prototype function.
// the third method to call prototype function. document.write("<a href='javascript:void(0);' onclick='" + this.instanceName + ".callback();'>instance call prototype function.</a>") }; myClass.prototype.callback=function() { alert("blueDestiny, never-online"); }; var a = new myClass("a"); a.toAlert(); //--> </SCRIPT>
