I hava an array generate by PHP server side, battleinfo.
After that, I would like to use JavaScript to loop the array, final output should be
//what i want like below
//example, first aaa is 0 random by Math.floor(Math.random() * (max - min + 1));
11:40:01 monkey first
11:40:06 hp-100
11:40:11 win
11:40:16 squrriel //when the battle[0] has been reach end of array, new aaa random, get value 2
11:40:21 hp-1000
11:40:26 win money 1000
11:40:31 monkey //random again when battle[2] has been finish.
But, my current error is aaa will be undefined, now output like below:
11:40:01 money
11:40:06 undefined
11:40:11 undefined
11:40:16 undefined //loop forever
Attach with snippet, please help and thank you.
var battleinfo = [
["monkey","hp-100","win"],
["crocok","hp-200","win money 100"],
["squrriel","hp-1000","win money 1000"],
];
var mystart = 0;
var battleinput = setInterval(function(){
var date = new Date();
var hour = ("0" + date.getHours()).substr(-2);
var minutes = ("0" + date.getMinutes()).substr(-2);
var seconds = ("0" + date.getSeconds()).substr(-2);
if(mystart <= 0){
var bb = 0;
var infocount = battleinfo.length;
min = 1;
max = Math.floor(infocount);
var aaa = Math.floor(Math.random() * (max - min + 1));//get random number, to decide which array to be show in div
var mystart = battleinfo[aaa].length;//count the array have how many value to be show in div
var randomItem = battleinfo[aaa][bb];//inset
mystart--;
bb++;
}else{
alert(aaa);
//HERE, aaa AND bb will be undefined value
var randomItem = battleinfo[aaa][bb];
bb++;
}
document.getElementById("advanturerun").innerHTML = "<pre>" + hour + ":" + minutes + ":" + seconds + " " + randomItem + "\n" + "</pre>" + document.getElementById("advanturerun").innerHTML;
}, 5000);<div id="advanturerun"> </div>They are undefined in the else block because they have never been defined at the time the else block runs. The if block will never run before the else block because it runs fresh on each iteration of the interval timer.
Or said differently: since you have defined mystart outside the interval callback, as soon as mystart gets to zero the else block runs and the if block never is run. Since the if block doesn't run, the vars are not assigned values.
You can fix this issue by placing var mystart = 0 inside the interval callback function.
But, there are many other issues in this code that will likely need a different question asked on SO.
