javascript父子通信_javascript技巧

<script> <BR>Object.prototype.addChild=function(oName, obj) <BR>{ <BR> eval("var p=this."+oName+"= new Object()"); <BR> this[oName]=obj; <BR> this[oName].parent=this; <BR>} <BR></script>
效果演示：

<script language="javascript" defer> var parent = { // say:function () { // alert("parent_say"); }, alert:function () { // alert("parent"); this.say(); } }; // parent.addChild("child", { // say:function () { // alert("child_say"); }, alert:function () { // alert("child"); this.parent.say(); } } ); //parent.child.alert(); //parent.alert(); var c = parent.child; c.alert(); </script> <script language="javascript"> Object.prototype.addChild=function(oName, obj) { eval("var p=this."+oName+"= new Object()"); this[oName]=obj; this[oName].parent=this; } </script>
