This is the same for the three other function calls which you have tried to make: <code>div.style.gridColumnEnd<\/code>, <code>div.style.gridRow<\/code>, and <code>div.style.gridRowEnd<\/code>.<\/p>\n<p>The second problem I can see is the way that you are using the variables inside of your inner function <code>tilex<\/code> and <code>tiley<\/code>. These variables are not visible at this point due to global, local, function, and block scoping of variables. So, you should refer to them as <code>this.tilex<\/code> and <code>this.tiley<\/code>.<\/p>\n<p>So the four function calls you tried to make should be:<\/p>\n<pre><code>div.style.gridColumnStart = this.tilex;\ndiv.style.gridColumnEnd = this.tilex + 1;\ndiv.style.gridRow = this.tiley;\ndiv.style.gridRowEnd = this.tiley + 1;\n<\/code><\/pre>\n<p>Also, you should call <code>getElementById()<\/code> on the <code>document<\/code> object.<\/p>\n<\/p>\n<div class=\"snippet\" data-lang=\"js\" data-hide=\"false\" data-console=\"true\" data-babel=\"false\">\n<div class=\"snippet-code\">\n<pre class=\"snippet-code-js lang-js prettyprint-override\"><code>function Tile(tilex, tiley) {\n  this.tilex = tilex;\n  this.tiley = tiley;\n\n  this.initTile = function initTile() {\n    var div = document.createElement('div');\n    div.id = (\"tile\" + this.tilex + \"_\" + this.tiley);\n    div.className = \"tile\";\n    div.innerHTML = this.tilex + \"_\" + this.tiley;\n    div.style.gridColumnStart = this.tilex;\n    div.style.gridColumnEnd = this.tilex + 1;\n    div.style.gridRow = this.tiley;\n    div.style.gridRowEnd = this.tiley + 1;\n    document.getElementById(\"tileGrid\").appendChild(div);\n  }\n}\n\nlet tile7_1 = new Tile(7, 1);\ntile7_1.initTile();\nlet tile2_6 = new Tile(2, 6);\ntile2_6.initTile();\nlet tile4_3 = new Tile(4, 3);\ntile4_3.initTile();\nlet tile7_7 = new Tile(7, 7);\ntile7_7.initTile();<\/code><\/pre>\n<pre class=\"snippet-code-css lang-css prettyprint-override\"><code>body {\n  background-color: rgba(236, 150, 119, 0.726);\n}\n\n\n\/*15 25*\/\n\n.grid {\n  display: grid;\n}\n\n#tileGrid {\n  background-color: rgb(20, 20, 20);\n  padding: 2px;\n  grid-template-columns: repeat(15, 20px);\n  grid-template-rows: repeat(25, 20px);\n  grid-auto-columns: 20px;\n}\n\n.tile {\n  background-color: rgba(100, 200, 100, 0.8);\n  border: 1px solid rgb(20, 20, 20);\n  font-size: 10px;\n}<\/code><\/pre>\n<pre class=\"snippet-code-html lang-html prettyprint-override\"><code>&lt;div class=\"grid\" id=\"tileGrid\"&gt;\n  &lt;div class=\"tile\" id=\"tile1\"&gt;1&lt;\/div&gt;\n  &lt;div class=\"tile\" id=\"tile2\"&gt;2&lt;\/div&gt;\n  &lt;div class=\"tile\" id=\"tile3\"&gt;3&lt;\/div&gt;\n  &lt;div class=\"tile\" id=\"tile4\"&gt;4&lt;\/div&gt;\n&lt;\/div&gt;<\/code><\/pre>\n<\/div>\n<\/div><\/div>\n<div class=\"mt24\"><\/div>\n<\/div>\n<p>            <span class=\"d-none\" itemprop=\"commentCount\">1<\/span> <\/p><\/div>\n<\/div>\n<p>[ad_2]<\/p>\n<p>solved Problem with JavaScript and adding a div to a grid at a specific (row, column) position [closed] <\/p>\n","protected":false},"excerpt":{"rendered":"<p>[ad_1] This is a very interesting problem.
