JavaScript 使用JavaScript获取URL参数

Posted 2021-05-20

function gup( name ) {
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results == null )
    return "";
  else
    return results[1];
}

// Example: gup('cat') will give you "meow" if the URL is http://example.com/?cat=meow
