call function based on xml value

[pelegk3]

i have a repeater :

<mx:Repeater id="btnRepeater" dataProvider="{rep.currentItem.BUTTON}">
                        <mx:Button label="{btnRepeater.currentItem}" click="getDefinitionByName('{btnRepeater.currentItem.@EVENT}')"/>
                    </mx:Repeater> 

and i want to call some how to a function with a value i get from the xml:
getDefinitionByName('{btnRepeater.currentItem.@Fun ctionName}')

anu idea?

Here is just a few ideas:

Create a function to parse the function name:

function ParseFunction(name:String):void{
    switch(name){
        case "function1":
            function1();
            break;
        case "function2":
            function2();
            break;
        case "function3":
            function3();
            break;
        case "function4":
            function4();
            break;
        default:
            trace("Parse Failed: Missing Function Name \""+name+"\"");
            break;
    }
}

OR you can do this

try{
    this[name]();//'this' being the scope of the class from where the methods/functions are located.
}catch{
    trace("Rut Row");
}

The second way is a bit cheeky, but really easy to get running. This makes debugging a great deal harder when stuff is missing or not running.

The first way takes a lot of writing- but gives you more direct control over what is happening.


Hope that helps =P

this isnt working :

getDefinitionByName('{btnRepeater.currentItem.@EVENT}')

var xmlData:XML=
<root>
<functionName>randomNumber</functionName>
<functionName>sortNumber</functionName>
</root>;
var xmlList:XMLList=xmlData.children();
var arr:Array=new Array();

function randomNumber(min,max) {
    return Math.round(Math.random() * max - min + 1 + min);
}
function sortNumber(a,b) {
    if (a<b) {
        return -1;
    } else if (a>b) {
        return 1;
    } else {
        return 0;
    }
}

for (var i:int=0; i<10; i++) {
    arr.push(this[xmlList[0]](4*i,10*i));
}
//--------------------------------------------
trace(arr);
trace(arr.sort(this[xmlData.children()[1]]));
//--------------------------------------------

i dont want to parse the xml, rather i want to get the data as part of the repeater
