使用此代码：

var html = document.getElementsByTagName("tr")[0].getElementsByTagName("td")[1].innerHTML
html = html.replace( /2012/g, "???" );
document.getElementsByTagName("tr")[0].getElementsByTagName("td")[1].innerHTML =html;

在此代码中，我想将2012替换为????

但我想用???替换值中的每个数字？但不能替换网址中的数字。

这可能吗？

Answer 1

由于网址都在网址中使用斜杠-，您可以执行以下操作：

html = html.replace( /[^\-]2012/g, " ???" );
