This article shows you how to use regular parsing URL parameters in JavaScript, the content is concise and easy to understand, it can definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Var url = "http://127.0.0.1/e/action/ShowInfo.php?classid=9&id=2";// defines the variable function parse_url (_ url) {/ / defines the function var pattern = / (\ w+) = (\ w+) / ig;// defines the regular expression var parames = {}; / / defines the array url.replace (pattern, function (a, b, c) {parames [b] = c;}); / * this is the most important. When replace matches classid=9. Then use to execute function (a classid=9,b bpg c); where the value of an is: the value of classid=9,b is 9; (this is a backreference. Because there are two submatches when defining a regular expression.) Then assign the array's key to the value of classid to 9; then finish. Then continue to match to id=2; at this time to execute function (an id,c); where the value of an is: the value of id=2,b is the value of id,c is 2; then the array is returned by assigning the key of the array to the value of id / return parames;//. } var parames = parse_url (url); alert (parames ['classid'] + "," + parames [' id']); / / Last print. Print the corresponding values of the array according to the key value. This is how to use regular parsing of URL parameters in JavaScript. Have you learned any knowledge or skills?
