二维数组随机生成器jQuery

Question

All rows always have same numbers, why? They should take random number to populate it. Also, how can I repair it? Once I saw answer here but now I cannot find it.

 var mapSizex = 5; var mapSizey = 6; var mapArray = []; $(function() { console.log("ready!"); $('#map-draw').html(drawMap()); }); function mapGenerator() { for (i = 0; i < mapSizex; i++) { for (x = 0; x < mapSizey; x++) { mapArray[i, x] = getRandom(1, 5); } } } function drawMap() { mapGenerator(); var map = ''; tileID = 0; for (i = 0; i < mapSizex; i++) { map = map + '<br style="clear: both;">'; for (x = 0; x < mapSizey; x++) { map = map + '<div class="tile tileID' + tileID + '">' + mapArray[i, x] + '</div>'; tileID++; } } return map; } function getRandom(min, max) { var x = Math.floor((Math.random() * max) + min); return x; } 

 .tile { float: left; height: 20px; width: 20px; border: 1px solid black; text-align: center; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="main-container"> <div id="map-container"> <div id="map-draw"></div> </div> </div> 

To post it I need to add some more content but all included information's should be enough to find what I mean.

Answer 1

here is a link to JSFIDDLE woking code

It should be mapArray[i][x] and I added mapArray[i]=[]; in the outer loop.

here is your fixed code:

var mapSizex=5;
var mapSizey=6;
var mapArray=[];

$(function() {
    console.log( "ready!" );
    $('#map-draw').html(drawMap());
});

function mapGenerator(){
    for(i=0;i<mapSizex;i++){
    mapArray[i]=[];
        for(x=0;x<mapSizey;x++){
            mapArray[i][x]= getRandom(1,5);
      console.log(i,x,getRandom(1,5))
        }
    }
}
function drawMap(){
    mapGenerator();
  console.log(mapArray)
    var map='';
    tileID=0;
    for(i=0;i<mapSizex;i++){
        map=map+'<br style="clear: both;">';
        for(x=0;x<mapSizey;x++){
            map=map+'<div class="tile tileID'+tileID+'">'+mapArray[i][x]+'</div>';
            tileID++;
        }
    }return map;
}
function getRandom(min,max) {
    var x = Math.floor((Math.random() * max) + min);
    return x;
}
