JavaScript实现9*9乘法表+隔行换色

方法一：

<script type="text/javascript">//9*9乘法表  隔行换色for (var i = 1; i <= 9; i++) {for (var j = 1; j <= i; j++) {if (i%2 == 0) { document.write("<span style='background-color:pink;'>"+i+'x'+j+'='+i*j+" </span>"); } else { document.write("<span style='background-color:grey;'>"+i+'x'+j+'='+i*j+" </span>"); }}document.write('<br />');}</script>

方法二：
