createClassObject(ComboBox,"my_combo",this.getNextHighestDepth(),{_x:90,_y:30});
my_combo.setSize(200);
my_combo.setStyle("openEasing",Elastic.easeOut);
my_combo.setStyle("openDuration",800);
//loadxml
myXML = new XML();
myXML.ignoreWhite = true;
myXML.load("http://www.webstudio.com.cn/wsswf/c...nks/example.xml");
myXML.onLoad =function(success){
// --
if(success){
links = new Array();
// --
for (var i = 0; i<myXML.firstChild.childNodes.length; i++) {
links.addItem({label:myXML.firstChild.childNodes[i].childNodes, data:myXML.firstChild.childNodes[i].attributes.url});
}
}else{
trace("cannot load xml");
}

// --
//add listenerobject
listenerObject = new Object();
listenerObject.change = function(event) {
//
//getURL(links[my_combo.selectedIndex].data,"_blank");
getURL(event.target.getValue(),"_blank");
trace(event.target.getValue());
};
// --

Hi,

Give a Trace Statement inside

myXML.onLoad =function(success){
trace(my_combo)
}


After the Result I hope U would Have understood what the problem is?!

HI eGoldy!

Hey Bellow is the Code which you have to replace ur myXML.onLoad() function.
Which will do ur job.



myXML.onLoad = function(success) {
// --
listenerObject = new Object();
listenerObject.change = function(event) {
//使用这一行同样可以达到目的。
//getURL(links[my_combo.selectedIndex].data,"_blank");
getURL(event.target.getValue(), "_blank");
trace(event.target.getValue());
};
my_combo.addEventListener("change", listenerObject);
if (success) {
links = new Array();
// --
for (var i = 0; i<myXML.firstChild.childNodes.length; i++) {
links.addItem({label:myXML.firstChild.childNodes[i].childNodes, data:myXML.firstChild.childNodes[i].attributes.url});
}
my_combo.dataProvider = links;
my_combo.dispatchEvent({type:"change"});
} else {
trace("cannot load xml");
}
// --
//加入侦听对象
// --
};


I hope This is What Your are asking For.!

Hi,

I did not get you even now...actually you said that the first link is not working when it is opened first time.I hope now it opens.If this is not the one you require then tell what actually you want in simple english so that i can help you.

[egoldy]

ok.

like my first thread question

when the swf run,you can click the first link and you will find it is not work.

After you click the second link,then click the first link ,it works fine.

that is my question.

Hi,

The Problem is when you go and choose the same option,the combo box does not dispatch the change event as the value of the combo box text is not changed hence when u click it first time the same link it won't work when you change it some thing else and then come back to the first link the event change has occured and so it works...I hope you got my point..

[egoldy]

ye,that is my question. as your said. it cannot chang :(

Thanks very very much for your reply.

Hi,

So for the above problem what you have to do is just have function which takes in the previous value of the combo box and the currently changed item and then dispatch the event change.
