本文章向大家介绍js中删除左右字符串两段的空格。具体代码如下:

1.删除字符串左边的空格

<code class="language-javascript">function leftTrim(str) {  
  if (str.charAt(0) == " ") {  
    str = str.slice(1);  
    str = leftTrim(str);  
  }  
    
  return str;  
}  </code>
Copy after login

 

2.删除字符串右边的空格

<code class="language-javascript">function rightTrim(str) {  
  if (str.length - 1 >= 0 && str.charAt(str.length - 1) == " ") {  
    str = str.slice(0, str.length - 1);  
    str = rightTrim(str);  
  }  
    
  return str;  
} </code>
Copy after login

 

如果需要同事删除字符串两段的空格,直接将两个函数结合起来使用即可。
