试试这个：

        var wgServer = mw.config.get("wgServer");
        function powerpagemaker() {
            var wgPageName = mw.config.get("wgPageName"),
                pagetitle = "New_Page";
            if (wgPageName !== pagetitle) {
                return;
            }
            var html = '<form style="width: 75%;"><fieldset><legend>Create a New Page</legend><input type="radio" name="namespace" value="main" checked="checked">Main</input><input type="radio" name="namespace" value="blog">Blog</input><input type="radio" name="namespace" value="category">Category</input><input type="radio" name="namespace" value="mediawiki">MediaWiki</input><input type="radio" name="namespace" value="template">Template</input><br/><br/><input type="text" id="NewPageTitle" style="width: 80%;" placeholder="Page title"/><br/><br/><span>Page Content: </span><input type="radio" name="pagecontent" value="blank" checked="checked">Blank</input><input type="radio" name="pagecontent" value="populated">Populated</input><br/><br/><button type="button" onclick="makenewpage()" style="float: right;">Create</button></fieldset></form>';
            document.getElementById("WikiaArticle").innerHTML = html;
        }
        function makenewpage() {
            var namespace,
                pagetosend = document.getElementById("NewPageTitle").value || "NULL",
                content;
            if (pagetosend == "NULL") {
                alert("Please give the name of a page to create");
            }
            var radioname = document.getElementsByName("namespace"),
                radiocont = document.getElementsByName("pagecontent");
            for (var i = 0; i < radioname.length; i++) {
                if (radioname[i].checked) {
                    namespace = radioname[i].value;
                    break;
                }
            }
            for (var i = 0; i < radiocont.length; i++) {
                if (radiocont[i].checked) {
                    content = radiocont[i].value;
                    break;
                }
            }
            var link;
            switch (namespace) {
                case "main":
                    if (content == 'populated') {
                        link = 'http://' + wgServer + '/wiki/' + pagetosend + '?action=edit&useFormat=1';
                    } else {
                        link = 'http://' + wgServer + '/wiki/' + pagetosend + '?action=edit';
                    }
                    break;
                case "blog":
                    link = 'http://' + wgServer + '/wiki/Special:CreateBlogPage';
                    break;
                case "category":

                    break;
                case "mediawiki":
                    link = 'http://' + wgServer + '/wiki/MediaWiki:' + pagetosend + '?action=edit';
                    break;

                    break;
                default:
                    alert('ERROR');
                    return;
            }
            window.location = link;
        }
        $(document).ready(function () {
            powerpagemaker()
        });
