Creating a dynamic grid of divs with Javascript
提问by Rowan
I want to create a grid of HTML divs that will have the same number of rows and columns but with the number of rows/columns being based on a particular number that would be passed to the Javascript function.
我想创建一个 HTML div 网格，该网格将具有相同的行数和列数，但行/列数基于将传递给 Javascript 函数的特定数字。
e.g. if the number is 3 the grid will be 3 rows and 3 columns
例如，如果数字为 3，则网格将为 3 行 3 列
if the number is 4 the grid will be 4 rows and 4 columns..etc
如果数字为 4，则网格将为 4 行 4 列..等
in the case of 3 the outputted code would need to look something like:
在 3 的情况下，输出的代码需要类似于：
<div class="row">
<div class="gridsquare">1</div>
<div class="gridsquare">2</div>
<div class="gridsquare">3</div>
</div>
<div class="row">
<div class="gridsquare">4</div>
<div class="gridsquare">5</div>
<div class="gridsquare">6</div>
</div>
<div class="row">
<div class="gridsquare">7</div>
<div class="gridsquare">8</div>
<div class="gridsquare">9</div>
</div>
What is a good way of iterating through javascript so that the correct elements can be identified to add the row div opening or closing tags (?)
什么是遍历 javascript 的好方法，以便可以识别正确的元素以添加行 div 开始或结束标记（？）

Something along these lines should work for ya.
沿着这些路线的东西应该对你有用。
<html><head>
<script language="javascript">
function genDivs(v){
var e = document.body; // whatever you want to append the rows to:
for(var i = 0; i < v; i++){
var row = document.createElement("div");
row.className = "row";
for(var x = 1; x <= v; x++){
var cell = document.createElement("div");
cell.className = "gridsquare";
cell.innerText = (i * v) + x;
row.appendChild(cell);
}
e.appendChild(row);
}
document.getElementById("code").innerText = e.innerHTML;
}
</script>
</head>
<body>
<input type="button" onclick="genDivs(6)" value="click me">
<code id="code"></code>

var n=4;//take grid column value as you want
for(var i = 0; i < n; i++) {
document.body.innerHTML+='<div class="row">';
for(j = 0; j < n; j++) {
document.body.innerHTML+='<div class="gridsquare">' + (i*5+j+1) + '</div>';
}
document.body.innerHTML+='</div>';
}

var grd="";
var rowCount=3;
for(var i=0; i<rowCount; i++){
/*here make whole string with row id to make identification of row then
you can select specific row */
您可以选择特定行 */
}
$(yourelement).append(grd);
I think it will be good way to identify row
我认为这将是识别行的好方法
