Top Naviation Menu is not loaded when script runs - SharePoint Foundation 2013 Oslo Master Page

sharepoint.stackexchange https://sharepoint.stackexchange.com/questions/223069

Question

I am trying to find the Top Navigation menu elements that are in the top part of my master page. So at the bottom of my master page I have added a script to fine the element on the page as follows:

var menulist = document.getElementById("zz14_RootAspMenu");

However, the value of menulist is always undefinded. If appears the content page has not finished loaded yet.

I have tried the following to delay the execution of the script but none have worked so far:

SP.SOD.executeFunc('sp.js', function () 
ExecuteOrDelayUntilScriptLoaded(processmenu(), "sp.js");
$(document).ready(function ()

Any suggestions would be greatly appreciated.

UPDATE ----- Here is the html from the rendered page that contains the element I an trying to get a reference to:

<div class=" noindex ms-core-listMenu-horizontalBox" id="zz13_V4QuickLaunchMenu" onclick="return AjaxNavigate$OnClickHook(event, this);">

    </ul>
</div>

UPDATE -- So have created a js file that I am trying to have run after the content of the master page loads using the RegisterModuleInit function. All my code is below:

Type.registerNamespace('MenuStuff')
MenuStuff.Functions = MenuStuff.Functions || {};
MenuStuff.ibUserInRole = false;

MenuStuff.Functions.menutohide = function (menutext) {
    var menulist = document.getElementById("zz14_RootAspMenu");

    alert("menulist :" + menulist);
    // Iterate LIs
    for (var itemi = 0; itemi < menulist.childNodes.length; itemi++) {
        var item = menulist.childNodes[itemi];
        if (item.nodeName == "LI" && item.innerHTML.indexOf(menutext) !== -1) {
            item.style.display = "none";
            break;
        }
    }
}

MenuStuff.Functions.checkRights = function (groupId) {
    try {
        MenuStuff.ibUserInRole = false;
        var userId = _spPageContextInfo.userId;
        var requestHeaders = { "accept": "application/json; odata=verbose" };

        $.ajax({
            url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/sitegroups(" + groupId + ")/users/getbyid(" + userId + ")",
            contentType: "application/json;odata=verbose",
            headers: requestHeaders,
            success: userInRole,
            error: userNotInRole
        });
        function userInRole(data, request) {
            // if we reach here, the current user belongs to the group Id 7 for the example
            MenuStuff.ibUserInRole = true;
        }
        function userNotInRole(error) {
            MenuStuff.ibUserInRole = false;
        }
    }
    catch (err) {
        alert("Error: " + err);
    }
}

MenuStuff.Functions.processmenu = function () {
    //error here
    MenuStuff.Functions.checkRights(6);  
    if (MenuStuff.ibUserInRole == false) {
        MenuStuff.Functions.menutohide("Board");
    }
}

RegisterModuleInit(
    _spPageContextInfo.siteServerRelativeUrl + 'Site Assets/newmenuscript.js',
    MenuStuff.Functions.processmenu);

alert("Before ProcessMenu again");
MenuStuff.Functions.processmenu();

 

 

I am using an Ajax Namespace per the information in this article [http://www.wictorwilen.se/the-correct-way-to-execute-javascript-functions-in-sharepoint-2013-mds-enabled-sites][1]

However my menulist is still null. Any suggestions??

UPDATE: I used the sample code the Alan provided and added the following to the end of my master page right before the end body tag. I updated the element to find as the ID of the item had changed.

<script type="text/javascript">
    _spBodyOnLoadFunctionNames.push("menuToHide");

    function menuToHide()
    { 
        var menulist = document.getElementById("zz13_V4QuickLaunchMenu");
        alert("menulist: " + menulist); 
    }
</script>

With this code, when Minimal Download Strategy (MDS) was enabled, the alert never occurred. When I disabled MDS, the alert worked. Any suggestions?

Was it helpful?

Solution

I could not get anything to fire AFTER all the content was loaded. What I had to do was use a JavaScript setTimeout function and wait for the content to finish loading. For anyone that this can help, my final code is below. I placed in a .js file in my Site Assets library and included it after the jquery library at the end of my Oslo master page. So far things seem to be working 

var iobj_menuList = null;
var ii_Count = 0;
var ib_UserIsAdmin = false;
var ib_UserIsARB = false;
var is_BoardMenuItem = '<li class="static"><a tabindex="0" class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/Site Board Pages/Board Of Directors.aspx"><span class="additional- background ms- navedit - flyoutArrow"><span class="menu- item - text">Board</span></span></a></li>';
var is_ARBMenuItem = '<li class="static"><a tabindex="0" class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/Site ARB Pages/Architectural Review Board.aspx"><span class="additional- background ms- navedit - flyoutArrow"><span class="menu- item - text">ARB</span></span></a></li>';

function checkRights() {
    try {
        var userId = _spPageContextInfo.userId;
        var requestHeaders = { "accept": "application/json; odata=verbose" };
        var groupID1 = 6;

        $.ajax({
            url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/sitegroups(" + groupID1 + ")/users/getbyid(" + userId + ")",
            contentType: "application/json;odata=verbose",
            headers: requestHeaders,
            success: userIsAdmin,
            fail: userNotAdmin,
            error: userNotAdmin
        });

        function userIsAdmin(data, request) {
            // if we reach here, the current user belongs to the group Id 7 for the example
            ib_UserIsAdmin = true;
            processmenu();
        }
        function userNotAdmin() {
            var groupID2 = 35;
            $.ajax({
                url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/sitegroups(" + groupID2 + ")/users/getbyid(" + userId + ")",
                contentType: "application/json;odata=verbose",
                headers: requestHeaders,
                success: userIsARB,
                fail: UserNotInARB,
                error: UserNotInARB
            });
            function userIsARB(data, request) {
                // if we reach here, the current user belongs to the group Id 7 for the example
                ib_UserIsARB = true;
                processmenu();
            }
            function UserNotInARB(error) {
                //user is not a member
            }
        }
        function AdminPermissionError(error) {
            alert("AdminPermissionError: " + error);
        }

    }
    catch (err) {
        alert("Error: " + err);
    }
}


function processmenu() {

    setTimeout(function () {
        if ($(".ms-quickLaunch") === "undefined" || ii_Count > 10) {
            ii_Count = ii_Count + 1;
            processmenu();
        }
        else if (ii_Count > 10) {
            alert("Menu Load timed out.")
        }
        else {
            //Append the board menu option
            var lobj_ItemToAdd = null;

            if (ib_UserIsAdmin)
            {
                lobj_ItemToAdd = is_BoardMenuItem;
            }
            else if (ib_UserIsARB)
            {
                lobj_ItemToAdd = is_ARBMenuItem;
            }
            $(lobj_ItemToAdd).insertAfter(".ms-quickLaunch li:eq(1)");            
        }
    }, 300);
}

checkRights();

 

OTHER TIPS

Have you tried this yet?

remove: SP.SOD.executeFunc('sp.js', function () ExecuteOrDelayUntilScriptLoaded(processmenu(), "sp.js"); $(document).ready(function () ...

replace with: _spBodyOnLoadFunctionNames.push("menuToHide")
