Question

Note $thisname and $thisvalue. I want $thisname to be the key/name and value assigned to it will be $thisvalue. As it currently is the name/value pair is invalid unless I replace $thisname with some static value which is not a variable.

function SaveNews($thisname, $thisvalue, $thispageid) {

    $.post('/Admin/SaveNews',

                { $thisname: $thisvalue, PageID: $thispageid },
                function (data) {

                });
            }

Answer 1

You cannot do that with JavaScript object literal syntax. You can, however, construct the object you need.

var params = { PageID: $thispageid };
params[$thisname] = $thisvalue;
$.post('/Admin/SaveNews', params, function(data) { ... });
