如何从标记恢复主干合并(How do I revert a trunk merge from a tag)

 如果内容真的只是1那么你的代码应该按原样运行（和parseInt ）。 因此，您的内容中必须包含有效数字以外的内容。 
 
 有时可能存在您无法看到的内容，例如，在下面的示例中，第二个td包含一个不可见的“零宽度空格”字符。 
 
 
 
 
 
  
var tdNodeListActual = document.querySelectorAll("td");

var good = tdNodeListActual[0].textContent;
var bad = tdNodeListActual[1].textContent;

alert(good + "==" + Number(good) + ", but " + bad + "==" + Number(bad))
 
  
<table><tr>
  <td>1</td>
  <td>&#8203;2</td>
</tr></table>
 
 
 
 
 
 您可以使用正则表达式删除所有非数字字符（ .和），例如： 
 
siteActual = siteActual.replace(/[^\d.,]/g, '');

Your code should work as-is if the content is really just 1 (as should parseInt). So there must be something other than valid numbers in your content.
 
Sometimes there can be content that you can't see, e.g. in the example below the second td contains an invisible "zero-width space" character.
 
 
 
 
 
  
var tdNodeListActual = document.querySelectorAll("td");

var good = tdNodeListActual[0].textContent;
var bad = tdNodeListActual[1].textContent;

alert(good + "==" + Number(good) + ", but " + bad + "==" + Number(bad))
 
  
<table><tr>
  <td>1</td>
  <td>&#8203;2</td>
</tr></table>
 
 
 
 
 
You can remove all non-digit characters (except . and ,) using a regex, e.g.:
 
siteActual = siteActual.replace(/[^\d.,]/g, '');
