我想创建一个 HTML div 网格，它具有相同的行数和列数，但行数/列数基于将传递给 Javascript 函数的特定数字。

例如，如果数字为 3，则网格将为 3 行和 3 列

如果数字是 4，网格将是 4 行和 4 列..等等

在 3 的情况下，输出的代码需要看起来像：

<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>

什么是通过 javascript 进行迭代的好方法，以便可以识别正确的元素以添加行 div 开始或结束标签（？）

这些方面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>
</body> 
</html>

结果：

  <div class="row">
    <div class="gridsquare">
      1

    <div class="gridsquare">
      2

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

您可以选择特定的行 */

}

$(yourelement).append(grd);

我认为这将是识别行的好方法
