Answer: Are you searching for how can I get query string values in JavaScript? Use the following JavaScript code.
You can use URLSearchParams which is simple and has decent (but not complete) browser support.
1 2 3 4 5 6 7 8 9 | function getParameterByName(name, url) { if (!url) url = window.location.href; name = name.replace(/[\[\]]/g, '\\$&'); var regex = new RegExp('[?&]' + name + '(=([^&#]*)|&|#|$)'), results = regex.exec(url); if (!results) return null; if (!results[2]) return ''; return decodeURIComponent(results[2].replace(/\+/g, ' ')); } |
How to use
1 2 3 4 5 | // query string: ?foo=lorem&bar=&baz var foo = getParameterByName('foo'); // "lorem" var bar = getParameterByName('bar'); // "" (present with empty value) var baz = getParameterByName('baz'); // "" (present with no value) var qux = getParameterByName('qux'); // null (absent) |
