宽度不能是两位或两位以上的数字，限制为1-9。你能解释一下为什么我的代码不接受两位数吗?

}<p>This HTML is not part of any of the problem, just the JS. This HTML is to display what it does.</p>
<p>Usage: <code>[width]*[height];color;color...</code></p>
<p>Example: <code>2*2;#dddddd;#aaaaaa;#aaaaaa;#777777</code>, produces a 2 by 2 square with a pixelated outset effect to it.</p>
<p>Try it out below:</p>
<input id="code" type="text"/><button onclick="document.getElementById('result').innerHTML = pixelPrint(document.getElementById('code').value);">Try</button>
<div id="result">
</div>
<p>Do not worry about the chopped up rows, I am sure you can find a CSS-based fix when you put the free function on your website.</p>if(sizeData.indexOf("*") == 1)
只有当*是字符串中的第二个字符时才会触发，即如果只有一个数字。
而不是尝试
if(sizeData.indexOf("*") !== -1)
(如果在字符串中找到一个*会触发)
