Hi there.

Is there anyway of doing the setTimeout() function in MsgPlus?
I need to pass an argument but you cannot do that with MsgPlus.AddTimer().

I tried it and it doesn't know about it because it says Object Expected.

I dunno, maybe eval() will work?

code:

---

function somefunction(param){
Debug.Trace(param);
}

function OnEvent_Timer(TimerId){
eval(TimerId);
}

MsgPlus.AddTimer("somefunction(\"test\")", 1000);

---

If you really want setTimeout functionality, you could try this class I made for my scripts. You have to note though that you can't use "normal" MsgPlus.AddTimer() calls unless you edit the OnEvent_Timer in this class.

Example usage:

Javascript code:

---

function somefunction(message) {
    Debug.Trace("Timer reached, message received: "+message);
}
 
var myTimer = new Timer(1000, somefunction, "test");
//Available methods:
myTimer.Refresh(); // Refreshes timer (stops and restarts)
myTimer.Cancel(); // Destructor

---

Javascript code:

---

/*
    File: Timer.js
    Desc: Class for timer handling
*/
var Timers = {};
var nTimersCount = 0;
 
var Timer = function(nInterval, fCallback, oParam) {
    this.Interval = nInterval;
    this.Callback = fCallback;
    this.Index = nTimersCount++;
    if(typeof oParam !== "undefined") this.Param = oParam;
    Timers[this.Index] = this;
    MsgPlus.AddTimer('Timer'+this.Index, this.Interval);
}
 
Timer.prototype = {
    "Refresh" : function() {
        MsgPlus.AddTimer('Timer'+this.Index, this.Interval);
    },
    "Cancel" : function() {
        MsgPlus.CancelTimer('Timer'+this.Index);
        delete Timers[this.Index];
    }
}
 
function OnEvent_Timer(sTimerId) {
    if(/^Timer(\d+)$/.test(sTimerId)) {
        var nIndex = 1*RegExp.$1;
        if(typeof Timers[nIndex].Param === "undefined") Timers[nIndex].Callback(Timers[nIndex]);
        else Timers[nIndex].Callback(Timers[nIndex], Timers[nIndex].Param);
    }
}

Hi there guys.

Thanks Matti!!

I didn't use your exact class.  I made my own custom object and changed a few things so I could pass multiple parameters.
But your Idea helped me a lot. Thanks again.  Here's what I wrote.  Please tell me if you find something wrong.

code:

---

//This is in TimerFunction.js
//Do Not Edit
var Timers = new Array();
var TimersIndex = 0;
function myTimer(FunctionName, Elapse, Parameter, Parameter2, Parameter3, Parameter4, Parameter5) {
    this.FunctionName=FunctionName
    this.Elapse=Elapse;
    this.TimerIndex=TimersIndex++;
    this.Refresh=TimerRefresh;
    this.Delete=TimerDelete;
    FunctionText=FunctionName + "(";
    //Set all parameters
    if (typeof Parameter !== "undefined") {
        this.Param1=Parameter;
        FunctionText+="TimerObj.Param1";
    }
    if (typeof Parameter2 !== "undefined") {
        this.Param2=Parameter2;
        FunctionText+=", TimerObj.Param2";
    }
    if (typeof Parameter3 !== "undefined") {
        this.Param3=Parameter3;
        FunctionText+=", TimerObj.Param3";
    }
    if (typeof Parameter4 !== "undefined") {
        this.Param4=Parameter4;
        FunctionText+=", TimerObj.Param4";
    }
    if (typeof Parameter5 !== "undefined") {
        this.Param5=Parameter5;
        FunctionText+=", TimerObj.Param5";
    }
    this.FunctionText = FunctionText + ")";
    //Set Object
    Timers[this.TimerIndex]=this;
    MsgPlus.AddTimer("myTimer"+this.TimerIndex.toString(), this.Elapse);
}

function TimerRefresh() {
    MsgPlus.AddTimer("myTimer"+this.TimerIndex.toString(), this.Elapse);
}

function TimerDelete() {
    MsgPlus.CancelTimer("myTimer"+this.Index);
     delete Timers[this.Index];
}

function OnEvent_Timer(TimerId) {
    if (TimerId.substring(0, 7) === "myTimer") {
        var TimerObj=Timers[TimerId.substring(7)];
        eval(TimerObj.FunctionText);
    }
}

Well, actually there's no need to add so many arguments. You could simply make another function which passes the right parameters and use that as callback, like so:

Javascript code:

---

function somefunction(arg1, arg2, arg3) {
    // Do something useful
}
 
// Method 1: hard-coded parameters inside new function
var callback = function(timer) {
    somefunction("aa", 123, 3.14159);
};
new Timer(1000, callback);
 
// Method 2: use array to get parameters
var callback = function(timer, args) {
    // Pass each element in the args array as parameter
    somefunction.apply(null, args);
};
var param = ["aa", 123, 3.14159];
new Timer(1000, callback, param);
