Get the id value from the page url

Question

In SharePoint how do you get the ID value from the url of the page you are on using javascript( Jquery,ajax, Rest..), e.g. I have the url like so: http:// ddd/mypage?ID=xx I tried before to retrieve the full url but it didn't get the ID and its value. so I have to get the ID value directly with the get method

Answer 1

you can use SharePoint’s GetUrlKeyValue() function to get item id. Example:

var itemId = GetUrlKeyValue("ID", false, location.href);

Answer 2

Use the following javascript function :

function getParameterByName(name) {  
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"), results = regex.exec(location.search);
    return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
var prodId = getParameterByName('prodId');

Answer 3

  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, " "));
            }

//ID Get//

var mid = getParameterByName("ID", window.location.href);

Problem resolved. Thanks for your contribution.

There is the code to get the ID value:

var query = window.location.search.substring(1);
var vars = query.split("=");
var ID= vars[1];
