如何为 window.location.pathname 实现通配符

Question

我有以下代码，我想让该函数在任何包含 "blog" 而不是特定 URL 的 URL 上运行。请帮助我正确的语法，谢谢。

window.setTimeout(function() {
  if (window.location.pathname != '/home/legal-documentation' &&
    window.location.pathname != '/home/blog/australian-business-news'
  ) {
    erOpenLoginRegisterbox(jQuery);
  }
  return false;
}, 1000);

Answer 1

您要找的是 Regular Expression。这些用于匹配特定的字符组合，在您的情况下，您可以使用 String.prototype.match() 以便使用此 RegEx 查找包含单词 "blog" 的字符串：

/blog/gi

或者，在您的函数中：

window.setTimeout(function() {
    if (window.location.pathname.match(/blog/gi)) {
        erOpenLoginRegisterbox(jQuery);
    }
    return false;
}, 1000);

Answer 2

我认为你正在寻找 indexOf: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/indexOf It will return -1 if it does not find the string it is passed, so testing for -1 seems to correlate with your approach. Furthermore, to be on the safe side, in case you also want to exclude blog in a case-insensitive manner (in other words, you want to test for Blog, blog, BLOG, etc.), I refer to pathname as though it were uppercase (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/toUpperCase)，然后将其与 'BLOG'

进行比较

window.setTimeout(function() {
    if (window.location.pathname.toUpperCase().indexOf('BLOG') === -1) {
        erOpenLoginRegisterbox(jQuery);
    }
    return false;
}, 1000);
