Question

我在JavaScript和HTML表格中完成了Conway的生命游戏编码表格中的逻辑单元格将分配唯一id's并基于id操作（基于4条规则）进行。
您可以在Codepen找到工作代码，或者我已将代码放在下面事情是它适用于任意数量的行和9列，如果给出超过9列，它们将不是唯一的id's，因此它以不期望的方式工作。
查询这是我可以为整个表格分配唯一ID的方式代码块tableInitialization是初始化部分。

(function(){
	$(document).ready(function(){
		var column = "", appendRow = "", inc = 1, selectedCells = [], toRemoveClass = [], toAddClass = [], maxValue;

			for(var row=1; row<=noOfRow; row++){
				for(var col=1; col<=noOfColumn; col++){
					column += "<td  id =" + inc+col + ">  </td>";
				}
				appendRow += "<tr>"+column+"</tr>";
				column= "";
				inc++;
			}
				$(".table").append(appendRow);
		};

			var noOfRow = parseInt($("#rowNo").val());

Answer 1

没有深入挖掘您的代码。您可以使用 col 和 row 索引构建ID，这样您就可以获得第一行11, 12, 13, 14, 15, ... 110, 111, 112等内容。如果没有分隔符，第11行第一个元素的ID也将是111。一旦你使用了一种分隔符，如＆＃39; _＆＃39;您的ID是唯一的：1_1, 1_2。

for(var row=1; row<=noOfRow; row++){
    for(var col=1; col<=noOfColumn; col++){
        column += "<td id =" + inc+"_"+col + ">  </td>";
        /* you also could add data attributes:
           data-row=\""+row+"\" data-col=\""+col+"\" 
        */
    }
    appendRow += "<tr>"+column+"</tr>";
    column= "";
    inc++;
}

查看您的代码，我认为您会遇到其他问题，因为有很多与＆＃34; 10＆＃34;相关的代码。例如：if((currentNumber-9) > 0 && (currentNumber-9) < maxValue){ - 如果您有超过9行，这将无法工作。但修复此问题将是完整游戏的重写版本。
