First Question here, too! Yay! Just moved this from AskUbuntu.
I am just about to finish a little private project for gaining some experience where i try to change the app layout so it works as a normal website (on Jimdo, so it was quite of a challenge first) without much JavaScript required but is fully functional on mobile view.
Since Jimdo serves naturally only the actual site, I had to implement an
if (activeTab.getAttribute('jimdo-target') != null)
location.href = activeTab.getAttribute('jimdo-target');
redirect into the __doSelectTab() function in tabs.js . (In js I took the values from the jimdo menu string to build the TABS menu with this link attribute)
Now everything works fine exept at page load the first tab is selected. I got it to set the .active and .inactive classes right easily, but it is not shifted to the left.
So my next idea is to let it initialize as always and then send a command to change to the current tab.
Do you have any idea how to manage this? I couldn't because of the this.thisandthat element I apparently don't really understand...
Most of you answering have the toolkit and the whole code, but I am listing the select function part of the tabs.js:
__doSelectTab: function(tabElement, forcedSelection) {
if ( ! tabElement)
return;
if (tabElement.getAttribute("data-role") !== 'tabitem')
return;
if (forcedSelection ||
(Array.prototype.slice.call(tabElement.classList)).indexOf('inactive') > -1) {
window.clearTimeout(t2);
activeTab = this._tabs.querySelector('[data-role="tabitem"].active');
offsetX = this.offsetLeft;
this._tabs.style['-webkit-transition-duration'] = '.3s';
this._tabs.style.webkitTransform = 'translate3d(-' + offsetX + 'px,0,0)';
this.__updateActiveTab(tabElement, activeTab);
if (activeTab.getAttribute('jimdo-target') != null)
location.href = activeTab.getAttribute('jimdo-target');
[].forEach.call(this._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)'), function (e) {
e.classList.remove('inactive');
});
var targetPageId = tabElement.getAttribute('data-page');
this.activate(targetPageId);
this.__dispatchTabChangedEvent(targetPageId);
} else {
[].forEach.call(this._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)'), function (el) {
el.classList.toggle('inactive');
});
var self = this;
t2 = window.setTimeout(function () {
var nonActiveTabs = self._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)');
[].forEach.call(nonActiveTabs, function (el) {
el.classList.toggle('inactive');
});
}, 3000);
}
},
...and my app.js hasn't anything special:
var UI = new UbuntuUI();
document.addEventListener('deviceready', function() { console.log('device ready') }, true);
$(document).ready(function () {
recreate_jimdo_nav();
UI.init();
});
So meanwhile found a simple workaround, however I'd still like to know if there is another way. Eventually I noticed the __doSelectTab() function is the one that executes the click, so it does nothing but to show the other tab names when they are hidden first. so I added the global value
var jnavinitialized = false;
at the beginning of the tabs.js and run
var t = this;
setTimeout(function(){t.__doSelectTab(t._tabs.querySelector('[data-role="tabitem"].jnav-current'))}, 0);
setTimeout(function(){t.__doSelectTab(t._tabs.querySelector('[data-role="tabitem"].jnav-current'))}, 1);
setTimeout(function(){jnavinitialized = true;}, 10);
at the top of the __setupInitialTabVisibility() function. Then I changed the location.href command to
if (activeTab.getAttribute('jimdo-target') != null && jnavinitialized)
location.href = activeTab.getAttribute('jimdo-target');
And it works. But originally I searched for a way to change the tab on command, not to run the command for selecting twice. So if you know a better or cleaner way, you are welcome!

I'm implemeting a very simple use case, and yet not only do I not find a solution, but I can't find any article that talks about it, as if I was the only one.
I want my custom Javascript to execute on every page of a given SharePoint site.
Easy, you'll say. Well, no. Far from it, like always with SharePoint.
Steps to reproduce :
Create a out-of-the-box publishing site
Include the custom javascript below using any of the means I describe below
Go to the site, to the home page. It's a publishing site, so by default you should have the left navigation pane with at least "Home" and "Documents" by default.
The first time you load the page, the javascript executes. Now, click on "documents". The page changes but the Javascript is not executed.
That's because SharePoint uses Ajax. Even if the MDS is disabled. It uses Ajax through the hash ( # ) in the URL.
For example, it transforms a very inocuous link like this one :
< a href src="/SitePages/Home.aspx">
into this URL when you click it:
https://your-url/sites/your-site/_layouts/15/start.aspx#/SitePages/Home.aspx
Here is my Javascript :
if (ExecuteOrDelayUntilScriptLoaded && _spBodyOnLoadFunctionNames) {
_spBodyOnLoadFunctionNames.push(ExecuteOrDelayUntilScriptLoaded(
function () {
alert("It's working!");
}, "sp.js"));
}
So, I've tried the following ways of including the Javascript :
Through a User Custom Action. I've used this very handy page to add it, but that's not relevant. The action is added to the site and I can see the JS in the DOM on first load. But then after I click on a link in the page and after SP uses Ajax, it does not execute it again.
By modifying the master page -- namely: seattle.html. at first I included it this way, simply under other native inclusions :
<head runat="server">
...
<!--SPM:<SharePoint:ScriptLink language="javascript" name="suitelinks.js" OnDemand="true" runat="server" Localizable="false"/>-->
<!--SPM:<SharePoint:ScriptLink language="javascript" Name="~sitecollection/SiteAssets/MYJAVASCRIPT.js" runat="server"/>-->
But then I read about AjaxDelta (here : https://msdn.microsoft.com/fr-fr/library/office/dn456543.aspx ) , and I moved my inclusion (still in the header) into < AjaxDelta >, like this :
<head runat="server">
...
<!--SPM:<SharePoint:AjaxDelta id="DeltaPlaceHolderAdditionalPageHead" Container="false" runat="server">-->
<!--SPM:<asp:ContentPlaceHolder id="PlaceHolderAdditionalPageHead" runat="server"/>-->
<!--SPM:<SharePoint:DelegateControl runat="server" ControlId="AdditionalPageHead" AllowMultipleControls="true"/>-->
<!--SPM:<SharePoint:ScriptLink language="javascript" Name="~sitecollection/SiteAssets/MYJAVASCRIPT.js" runat="server"/>-->
<!--SPM:</SharePoint:AjaxDelta>-->
...and yet nothing works. The Javascript is never executed when switching between pages of the same site by clicking on SharePoint's "managed" links.
I'm looking for a solution that handles elegantly SharePoint's Ajax, not something heavy and risky that hijacks every hyperlink on a page. For example I've tried to hook my code onto ajaxNavigate methods (for example : addNavigate) but I'm not sure I understand what's actualy going on there and if it could be of any help to me.
EDIT :
There seems to be a consensus (for example, here at the very bottom) that User Custom Actions get executed no matter what -- because SharePoint allegedly places their ScriptLink into the AjaxDelta for some reason. Well, that's not what I witnessed.
There's another consensus that this issue can be adressed by using "RegisterModuleInit". This doesn't work for me either.
I'm extermely puzzled. I think those two solutions do address navigation issues when the user clicks on a link and then clicks "back". But it does NOT address SharePoint's clever "managed", Ajax-riddled, hyperlinks.
I've finally found a solution that never seems to fail so far. That's a real relief.
Short answer: use asyncDeltaManager.add_endRequest
This MSDN discussion suggests a simple way to implement it:
https://social.msdn.microsoft.com/Forums/office/en-US/1ae292b4-3589-46f6-bedc-7bd9dc741f1b/javascript-code-to-execute-after-all-the-elements-and-css-are-loaded?forum=appsforsharepoint
$(function () {
ExecuteOrDelayUntilScriptLoaded(function () {
if (typeof asyncDeltaManager != "undefined")
asyncDeltaManager.add_endRequest(MYCUSTOMCODE); //execute it after any ajax event
else
MYCUSTOMCODE(); //execute it at first load
}, "start.js");
});
This shows how to include it properly in SharePoint's cycle (with ExecuteOrDelayUntilScriptLoaded )

Here's the problem. I'm making a callback to the server that receives an MVC partial page. It's been working great, it calls the success function and all that. However, I'm calling a function after which iterates through specific elements:
$(".tool-fields.in div.collapse, .common-fields div.collapse").each(...)
Inside this, I'm checking for a specific attribute (custom one using data-) which is also working great; however; the iterator never finishes. No error messages are given, the program doesn't hold up. It just quits.
Here's the function with the iterator
function HideShow() {
$(".tool-fields.in div.collapse, .common-fields div.collapse").each(function () {
if (IsDataYesNoHide(this)) {
$(this).collapse("show");
}
else
$(this).collapse("hide");
});
alert("test");
}
Here's the function called in that, "IsDataYesNoHide":
function IsDataYesNoHide(element) {
var $element = $(element);
var datayesnohide = $element.attr("data-yes-no-hide");
if (datayesnohide !== undefined) {
var array = datayesnohide.split(";");
var returnAnswer = true;
for (var i in array) {
var answer = array[i].split("=")[1];
returnAnswer = returnAnswer && (answer.toLowerCase() === "true");
}
return returnAnswer;
}
else {
return false;
}
}
This is the way the attribute appears
data-yes-no-hide="pKanban_Val=true;pTwoBoxSystem_Val=true;"
EDIT: Per request, here is the jquery $.post
$.post(path + conPath + '/GrabDetails', $.param({ data: dataArr }, true), function (data) {
ToggleLoader(false); //Page load finished so the spinner should stop
if (data !== "") { //if we got anything back of if there wasn't a ghost record
$container.find(".container").first().append(data); //add the content
var $changes = $("#Changes"); //grab the changes
var $details = $("#details"); //grab the current
SplitPage($container, $details, $changes); //Just CSS changes
MoveApproveReject($changes); //Moves buttons to the left of the screen
MarkAsDifferent($changes, $details) //Adds the data- attribute and colors differences
}
else {
$(".Details .modal-content").removeClass("extra-wide"); //Normal page
$(".Details input[type=radio]").each(function () {
CheckOptionalFields(this);
});
}
HideShow(); //Hide or show fields by business logic
});
For a while, I thought the jquery collapse was breaking, but putting the simple alert('test') showed me what was happening. It just was never finishing.
Are there specific lengths of time a callback function can be called from a jquery postback? I'm loading everything in modal views which would indicate "oh maybe jquery is included twice", but I've already had that problem for other things and have made sure that it only ever includes once. As in the include is only once in the entire app and the layout is only applied to the main page.
I'm open to any possibilities.
Thanks!

Found the problem. I had a variable that was sometimes being set as undefined cause it to silently crash. I have no idea why there was no error message.
Rewriting the question -
I am trying to make a page on which if user leave the page (either to other link/website or closing window/tab) I want to show the onbeforeunload handeler saying we have a great offer for you? and if user choose to leave the page it should do the normal propogation but if he choose to stay on the page I need him to redirect it to offer page redirection is important, no compromise. For testing lets redirect to google.com
I made a program as follows -
var stayonthis = true;
var a;
function load() {
window.onbeforeunload = function(e) {
if(stayonthis){
a = setTimeout('window.location.href="http://google.com";',100);
stayonthis = false;
return "Do you really want to leave now?";
}
else {
clearTimeout(a);
}
};
window.onunload = function(e) {
clearTimeout(a);
};
}
window.onload = load;
but the problem is that if he click on the link to yahoo.com and choose to leave the page he is not going to yahoo but to google instead :(
Help Me !! Thanks in Advance
here is the fiddle code
here how you can test because onbeforeunload does not work on iframe well
This solution works in all cases, using back browser button, setting new url in address bar or use links.
What i have found is that triggering onbeforeunload handler doesn't show the dialog attached to onbeforeunload handler.
In this case (when triggering is needed), use a confirm box to show the user message. This workaround is tested in chrome/firefox and IE (7 to 10)
http://jsfiddle.net/W3vUB/4/show
http://jsfiddle.net/W3vUB/4/
EDIT: set DEMO on codepen, apparently jsFiddle doesn't like this snippet(?!)
BTW, using bing.com due to google not allowing no more content being displayed inside iframe.
http://codepen.io/anon/pen/dYKKbZ
var a, b = false,
c = "http://bing.com";
function triggerEvent(el, type) {
if ((el[type] || false) && typeof el[type] == 'function') {
el[type](el);
}
}
$(function () {
$('a:not([href^=#])').on('click', function (e) {
e.preventDefault();
if (confirm("Do you really want to leave now?")) c = this.href;
triggerEvent(window, 'onbeforeunload');
});
});
window.onbeforeunload = function (e) {
if (b) return;
a = setTimeout(function () {
b = true;
window.location.href = c;
c = "http://bing.com";
console.log(c);
}, 500);
return "Do you really want to leave now?";
}
window.onunload = function () {
clearTimeout(a);
}
It's better to Check it local.
Check out the comments and try this: LIVE DEMO
var linkClick=false;
document.onclick = function(e)
{
linkClick = true;
var elemntTagName = e.target.tagName;
if(elemntTagName=='A')
{
e.target.getAttribute("href");
if(!confirm('Are your sure you want to leave?'))
{
window.location.href = "http://google.com";
console.log("http://google.com");
}
else
{
window.location.href = e.target.getAttribute("href");
console.log(e.target.getAttribute("href"));
}
return false;
}
}
function OnBeforeUnLoad ()
{
return "Are you sure?";
linkClick=false;
window.location.href = "http://google.com";
console.log("http://google.com");
}
And change your html code to this:
<body onbeforeunload="if(linkClick == false) {return OnBeforeUnLoad()}">
try it
</body>
After playing a while with this problem I did the following. It seems to work but it's not very reliable. The biggest issue is that the timed out function needs to bridge a large enough timespan for the browser to make a connection to the url in the link's href attribute.
jsfiddle to demonstrate. I used bing.com instead of google.com because of X-Frame-Options: SAMEORIGIN
var F = function(){}; // empty function
var offerUrl = 'http://bing.com';
var url;
var handler = function(e) {
timeout = setTimeout(function () {
console.log('location.assign');
location.assign(offerUrl);
/*
* This value makes or breaks it.
* You need enough time so the browser can make the connection to
* the clicked links href else it will still redirect to the offer url.
*/
}, 1400);
// important!
window.onbeforeunload = F;
console.info('handler');
return 'Do you wan\'t to leave now?';
};
window.onbeforeunload = handler;
Try the following, (adds a global function that checks the state all the time though).
var redirected=false;
$(window).bind('beforeunload', function(e){
if(redirected)
return;
var orgLoc=window.location.href;
$(window).bind('focus.unloadev',function(e){
if(redirected==true)
return;
$(window).unbind('focus.unloadev');
window.setTimeout(function(){
if(window.location.href!=orgLoc)
return;
console.log('redirect...');
window.location.replace('http://google.com');
},6000);
redirected=true;
});
console.log('before2');
return "okdoky2";
});
$(window).unload(function(e){console.log('unloading...');redirected=true;});
<script>
function endSession() {
// Browser or Broswer tab is closed
// Write code here
alert('Browser or Broswer tab closed');
}
</script>
<body onpagehide="endSession();">
I think you're confused about the progress of events, on before unload the page is still interacting, the return method is like a shortcut for return "confirm()", the return of the confirm however cannot be handled at all, so you can not really investigate the response of the user and decide upon it which way to go, the response is going to be immediately carried out as "yes" leave page, or "no" don't leave page...
Notice that you have already changed the source of the url to Google before you prompt user, this action, cannot be undone... unless maybe, you can setimeout to something like 5 seconds (but then if the user isn't quick enough it won't pick up his answer)
Edit: I've just made it a 5000 time lapse and it always goes to Yahoo! Never picks up the google change at all.
there is a page with some basic HTML that I cannot touch that looks like this:
<a class="continue-shopping" href="https://someURL">Continue shopping</a>
what I want to do is send the user to a different link when they click on the someURL text link. the user can come to a page containing this html from many other pages.
i have tried many hours but cannot get my js to recognize a click event for a class associated with hyperlinked text. i could really use some help here. this is the js code i wrote which does not work
window.onload = function() {
prepEventHandler();
}
function prepEventHandler () {
var myClass = document.getElementsByClassName("continue-shopping");
myClass[0].onclick=window.open(document.referrer,"_self");
/* which make my pages go haywire OR THIS -- which also does not work */
myClass[0].addEventListener("click", function() {
window.open(document.referrer,"_self");
}
)
}
It just keeps ignoring the second function, and I am sure I am doing some really basic that is wrong. Again, thanks for any help!
Apart from preventDefault() you could also use return false
window.onload = function () {
var myClass = document.querySelector(".continue-shopping")
.onclick = function () {
window.location.href = "http://elsewere.com";
return false;
}
}
this code should work but it no longer does and i do not know why any hint much appreciated - there seems to be some problem with myClass[0]
window.onload = function() {
var myClass = document.getElementsByClassName('continue-shopping');
myClass[0].addEventListener("click", function(e) {
e.preventDefault();
window.location.href = document.referrer;
});
}
I'm developing a simple gadget for Windows 7 as a learning exercise.
I read in this article (under the subtopic Gadgets and Script) that to initialize the gadget, you should use document.onreadystatechange instead of events such as onLOad. I've seen it in the example project code I've looked through as well. This is what I came up with for my project.
document.onreadystatechange = function()
{
if(document.readyState == "complete")
{
System.Gadget.settingsUI = "settings.html"; //this line enables the settings UI
System.Gadget.onSettingsClosed = settingsClosed;
}
}
However when I use this snippet in my work, it doesn't work. The Options button in the gadget doesn't show up. If I use onLoad, it works. I have installed 2 gadgets. Each of them use these 2 methods. One use onLoad and the other use document.onreadystatechange. And both of them works!
Now I'm confused why it doesn't work with my gadget. Is there any important part I'm overlooking?
try something along these lines,
move your onsettingsclosed to a different event and call the function with it
document.onreadystatechange = function()
{
if(document.readyState=="complete")
{
var searchTags = System.Gadget.Settings.read("searchTags");
if(searchTags != "")
{
searchBox.value = searchTags;
}
}
}
System.Gadget.onSettingsClosing = function(event)
{
if (event.closeAction == event.Action.commit)
{
var searchTags = searchBox.value;
if(searchTags != "")
{
System.Gadget.Settings.write("searchTags", searchTags);
}
event.cancel = false;
}
}
