I found this peace of code some where on the web.
I tried it and it works fine:
var onHashChange = function(event) {
//get hash function
var getHashValue = function() {
var arr = window.location.hash.split("#");
var hasValue = arr[1];
//sets default
if (typeof hasValue == "undefined") {
return false;
}
var hashLen = hasValue.indexOf("?");
if(hashLen>0){
hasValue = hasValue.substring(0,hashLen);
}
return hasValue;
}
//last hash
var lastHash = getHashValue();
//checker
(function watchHash() {
var hash = getHashValue();
if (hash !== lastHash) {
event();
lastHash = hash;
}
var t = setTimeout(watchHash, 100);
})();
}
BUT when the function that would be called in the onHashChange many time, it will be repeated for ever.
onHashChange(function() {
console.log("changed");
});
when am at the same page and the hash is being changed, the console.log will be full of "changed" text even when I made only 3 changes for the hash in the page!
Well, am calling a function "instead of console.log" that at the same time will callback onHashChange again
Any trick to get over it?
Thanks :)
This should work well on hash change and url change via history.replaceState and history.pushState!
var onUrlChange = function(event) {
var getHashValue = function () {
var arr = window.location.hash.split("#");
var hasValue = arr[1];
if (typeof hasValue == "undefined") {
return false;
}
var hashLen = hasValue.indexOf("?");
if (hashLen > 0) {
hasValue = hasValue.substring(0, hashLen);
}
return hasValue;
}
var getUrlValue = function () {return window.location.pathname;}
var lastHash = getHashValue();
var lastUrl = getUrlValue();
(function watchPath() {
var hash = getHashValue();
var url = getUrlValue();
if (hash !== lastHash) {
event();
lastHash = hash;
}
if (url !== lastUrl) {
event();
lastUrl = url;
}
var t = setTimeout(watchPath, 100);
})();
}
onUrlChange(function () {
//somthing
});

I have this grid that i am creating using knockoutjs, it works perfectly at first, now i am using a window.location.hash to run another query, it works too and query returns the correct amount of data however when i insert it within the observableArray (which gets inserted correctly as well), the grid doesn't update the data and shows the old data... I'm using removeAll() function on the observableArray as well before inserting new set of data but it wont update my grid, i suspect there is something wrong with the DOM?
I should mention when i reload the page (since the page's url keeps the hash for query) my grid shows the data and works perfectly. for some reason it needs to reload the page and doesn't work without,
Here is my JS:
if (!ilia) var ilia = {};
ilia.models = function () {
var self = this;
this.pageCount = ko.observable(0);
//this is the observableArray that i am talking about ++++++++
this.items = ko.observableArray();
var $pagination = null;
var paginationConfig = {
startPage: 1,
totalPages: 20,
onPageClick: function (evt, page) {
self.generateHash({ pageNum: page });
self.getData();
}
}
var hashDefault = {
pageNum: 1,
pageSize: 20,
catId: null,
search: ""
}
this.dataModel = function (_id, _name, _desc, _thumb, _ext) {
var that = this;
this.Id = ko.observable(_id);
this.Name = ko.observable(_name);
this.Desc = ko.observable(_desc);
this.Url = '/site/ModelDetail?id=' + _id;
var b64 = "data:image/" + _ext + ";base64, ";
this.thumb = ko.observable(b64 + _thumb);
}
this.generateHash = function (opt) {
//debugger;
var props = $.extend(hashDefault, opt);
var jso = JSON.stringify(props);
var hash = window.location.hash;
var newHash = window.location.href.replace(hash, "") + "#" + jso;
window.location.href = newHash;
return jso;
}
this.parseHash = function () {
var hash = window.location.hash.replace("#", "");
var data = JSON.parse(hash);
if (data)
data = $.extend(hashDefault, data);
else
data = hashDefault;
return data;
}
var _cntrl = function () {
var _hdnCatName = null;
this.hdnCatName = function () {
if (_hdnCatName == null)
_hdnCatName = $("hdnCatName");
return _hdnCatName();
};
var _grid = null;
this.grid = function () {
if (_grid == null || !_grid)
_grid = $("#grid");
return _grid;
}
this.rowTemplate = function () {
return $($("#rowTemplate").html());
}
}
this.createPagnation = function (pageCount, pageNum) {
$pagination = $('#pagination-models');
if ($pagination && $pagination.length > 0)
if (paginationConfig.totalPages == pageCount) return;
var currentPage = $pagination.twbsPagination('getCurrentPage');
var opts = $.extend(paginationConfig, {
startPage: pageNum > pageCount ? pageCount : pageNum,
totalPages: pageCount,
onPageClick: self.pageChange
});
$pagination.twbsPagination('destroy');
$pagination.twbsPagination(opts);
}
this.pageChange = function (evt, page) {
var hash = self.parseHash();
if (hash.pageNum != page) {
self.generateHash({ pageNum: page });
self.getData();
}
}
this.getData = function () {
var _hash = self.parseHash();
inputObj = {
pageNum: _hash.pageNum,
pageSize: _hash.pageSize,
categoryId: _hash.catId
}
//debugger;
//console.log(_hash);
if (inputObj.categoryId == null) {
ilia.business.models.getAll(inputObj, function (d) {
//debugger;
if (d && d.IsSuccessfull) {
self.pageCount(d.PageCount);
self.items.removeAll();
_.each(d.Result, function (item) {
self.items.push(new self.dataModel(item.ID, item.Name, item.Description, item.Thumb, item.Extention));
});
if (self.pageCount() > 0)
self.createPagnation(self.pageCount(), inputObj.pageNum);
}
});
}
else {
ilia.business.models.getAllByCatId(inputObj, function (d) {
if (d && d.IsSuccessfull) {
self.pageCount(d.PageCount);
self.items.removeAll();
console.log(self.items());
_.each(d.Result, function (item) {
self.items.push(new self.dataModel(item.ID, item.Name, item.Description, item.Thumb, item.Extention));
});
// initializing the paginator
if (self.pageCount() > 0)
self.createPagnation(self.pageCount(), inputObj.pageNum);
//console.log(d.Result);
}
});
}
}
this.cntrl = new _cntrl();
};
And Initialize:
ilia.models.inst = new ilia.models();
$(document).ready(function () {
if (!window.location.hash) {
ilia.models.inst.generateHash();
$(window).on('hashchange', function () {
ilia.models.inst.getData();
});
}
else {
var obj = ilia.models.inst.parseHash();
ilia.models.inst.generateHash(obj);
$(window).on('hashchange', function () {
ilia.models.inst.getData();
});
}
ko.applyBindings(ilia.models.inst, document.getElementById("grid_area"));
//ilia.models.inst.getData();
});
Would perhaps be useful to see the HTML binding here as well.
Are there any console errors? Are you sure the new data received isn't the old data, due to some server-side caching etc?
Anyhow, if not any of those:
Are you using deferred updates? If the array size doesn't change, I've seen KO not being able to track the properties of a nested viewmodel, meaning that if the array size haven't changed then it may very well be that it ignores notifying subscribers. You could solve that with
self.items.removeAll();
ko.tasks.runEarly();
//here's the loop
If the solution above doesn't work, could perhaps observable.valueHasMutated() be of use? https://forums.asp.net/t/2056128.aspx?What+is+the+use+of+valueHasMutated+in+Knockout+js
Works great in Firefox / Chrome / Microsoft Edge, but when the button is clicked in the latest Internet Explorer 11, it takes two clicks to toggle class when it should only take one. Everything else performs as it should (it plays and stops the music when it should).
JSFiddle Example
<script>
$(".play").on('click', function () {
var key = $(this).attr('key');
EvalSound(this, key);
var this_play = $(this);
$(".play").each(function () {
if ($(this)[0] != this_play[0]) {
$(this).removeClass("pause");
}
});
$(this).toggleClass("pause");
});
var thissound = new Audio();
var currentKey;
function EvalSound(el, key) {
thissound.addEventListener('ended', function () {
// done playing
$(el).removeClass("pause");
});
if (currentKey !== key) thissound.src = "exclusive/" + key + ".mp3";
currentKey = key;
if (thissound.paused) thissound.play();
else thissound.pause();
thissound.currentTime = 0;
currentPlayer = thissound;
}
</script>
Since toggleClass normally works in IE I think the problem was just something to do with the way this code was written: Here is an IE one click working version in JS Fiddle: http://jsfiddle.net/jeffd/2fjnmdkb/22/

});
$(this).toggleClass("pause");
var player_bottom = $(".playerbottom");
if (currentKey == key || !player_bottom.hasClass('pausebottom')) {

I have running script which moves the tr elements from one container to another on double click. But i have below mentioned issues:
1) If we do are very quick double-click on elements than it moves but its values doesn't come, it shows empty tags.
2) I want to change the background color on double click and it color should remove when we click outside or another elements.

Your code looks pretty nice. You should also use in order to register from jQuery a single click event the native method .click(...). So please change the following line
tmContainer.find("table.cv-invitees").on('click', 'tr', function (e) {
To:
tmContainer.find("table.cv-invitees").click(function (e) {
and everything should work fine. For some strange reasons the function
$("#someelement").on("click", ...);
does not work always, only sometimes. JQuery officially recommends you to use the native functions for predefined events (such as onclick, onkeyup, onchange etc.) because of this strange behavior.
Edit:
If dblick does not work now, then make 2 lines please, like this:
tmContainer.find("table.cv-invitees").click(function (e) {
// [...]
;
tmContainer.find("table.cv-invitees").dbclick(function (e) {
// [...]
Edit2:
If it does not work, too, then please remove the single click event listener when you are in the .click() closure. Because if this happens, jQuery´s behavior is to treat it always as a single click. So, in other words dblick() will never be triggered, because .click() will always happens before. And then jQuery won´t count up to 2 fast clicks. Expect the unexpected^^
Edit3: This is the full code, which should hopefully work now as it is:

I guess that you interpret in your special case a double click as 3 times clicked at the same table entry. And if a user do so and if the time difference between first and second click is longer than one second, a double click will be fired. I think should be the solution to deal with this special case.
Edit 4: Please test, if it is possible to click on 3 different table column and get also double click fired. I think this is an disadvantage on how my code handles the double click. So, you need to know from which table column you have already 1 to 3 clicks set. How can we do this? Basically, there are 3 possibilities to do this:
(HTML5 only:) Make data attribute on each tr and the value for this data attribute
should be the clicks already clicke on this tr.
Define a global object key/value pair object, which holds the
event-ID (but I don´t know how to get this back by jQuery driven
events) as the key and the amount of clicks already done as the
value. And then if you are on the next click, you can decide what is
to do now for this tr. This is my favorite alternative!
Last but not least: Only register the click event on every tr and
make for each click-registering an own global area, so that we just
avoid the actual problem. You can do this e. g. by making an JS
Object which hold a member variable as the iclickCounter and you
make a new object of this class, each time a new click event is
registered. But this alternative need a lot more code and is main-memory-hungry.
All of thes possible options need a wrap around your click event, e. g. a loop, that iterates over all tr elements in the given table. You did this already partially by calling the jQuery-function .find(..). This executes the closure on every found html element. So, in your case on all tr elements in the searched table. But what you need to do is to make the workaround of one of my options given above.
I am trying to create collapsible DIVs that react to links being clicked. I found how to do this using "next" but I wanted to put the links in a separate area. I came up with this which works...
JSFiddle - Works
function navLink(classs) {
this.classs = classs;
}
var homeLink = new navLink(".content-home");
var aboutLink = new navLink(".content-about");
var contactLink = new navLink(".content-contact");
var lastOpen = null;
$('.home').click(function() {
if(lastOpen !== null) {
if(lastOpen === homeLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-home').slideToggle('slow');
lastOpen = homeLink;
}
);
$('.about').click(function() {
if(lastOpen !== null) {
if(lastOpen === aboutLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-about').slideToggle('slow');
lastOpen = aboutLink;
}
);
$('.contact').click(function() {
if(lastOpen !== null) {
if(lastOpen === contactLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-contact').slideToggle('slow');
lastOpen = contactLink;
}

I am now trying to create the same result but with a single function instead of one for each link. This is what I came up with....
function navLink(contentClass, linkClass, linkId) {
this.contentClass = contentClass;
this.linkClass = linkClass;
this.linkId = linkId;
}
var navs = [];
navs[0] = new navLink(".content-home", "nav", "home");
navs[1] = new navLink(".content-about", "nav", "about");
navs[2] = new navLink(".content-contact", "nav", "contact");
var lastOpen = null;
$('.nav').click(function(event) {
//loop through link objects
var i;
for (i = 0; i < (navsLength + 1); i++) {
//find link object that matches link clicked
if (event.target.id === navs[i].linkId) {
//if there is a window opened, close it
if (lastOpen !== null) {
//unless it is the link that was clicked
if (lastOpen === navs[i]) {
return;
} else {
//close it
$(lastOpen.contentClass).slideToggle('fast');
}
}
//open the content that correlates to the link clicked
$(navs[i].contentClass).slideToggle('slow');
navs[i] = lastOpen;
}
}
});
JSFiddle - Doesn't Work
No errors so I assume that I am just doing this completely wrong. I've been working with Javascript for only about a week now. I've taken what I've learned about arrays and JQuery events and tried to apply them here. I assume I'm way off. Thoughts? Thanks
You just forgot to define navsLength:
var navsLength=navs.length;
Of course you could also replace it with a $().each loop as you're using jQuery.
[Update] Two other errors I corrected:
lastOpen=navs[i];
for(i=0; i < navsLength ; i++)
Demo: http://jsfiddle.net/jMzPJ/4/
Try:
var current, show = function(){
var id = this.id,
doShow = function() {
current = id;
$(".content-" + id).slideToggle('slow');
},
toHide = current && ".content-" + current;
if(current === id){ //Same link.
return;
}
toHide ? $(toHide).slideToggle('fast', doShow): doShow();;
};
$("#nav").on("click", ".nav", show);

I'm getting WebResource error in my asp.Net page:
var __pendingCallbacks = new Array();
Microsoft JScript runtime error: 'Array' is undefined
I have no idea what might cause this to happen. Isn't Array part of Javascript itself? Any help would be appreciated.
EDIT
The problem is that this isn't code that I wrote, it's built into the page structure in asp.Net.
EDIT
The problem only occurs in IE9 and only when run in IE9 mode (not compatibility)
Code:
(This is dynamically generated code, sorry for the length. Problem is about halfway down)
function WebForm_PostBackOptions(eventTarget, eventArgument, validation, validationGroup, actionUrl, trackFocus, clientSubmit) {
this.eventTarget = eventTarget;
this.eventArgument = eventArgument;
this.validation = validation;
this.validationGroup = validationGroup;
this.actionUrl = actionUrl;
this.trackFocus = trackFocus;
this.clientSubmit = clientSubmit;
}
function WebForm_DoPostBackWithOptions(options) {
var validationResult = true;
if (options.validation) {
if (typeof(Page_ClientValidate) == 'function') {
validationResult = Page_ClientValidate(options.validationGroup);
}
}
if (validationResult) {
if ((typeof(options.actionUrl) != "undefined") && (options.actionUrl != null) && (options.actionUrl.length > 0)) {
theForm.action = options.actionUrl;
}
if (options.trackFocus) {
var lastFocus = theForm.elements["__LASTFOCUS"];
if ((typeof(lastFocus) != "undefined") && (lastFocus != null)) {
if (typeof(document.activeElement) == "undefined") {
lastFocus.value = options.eventTarget;
}
else {
var active = document.activeElement;
if ((typeof(active) != "undefined") && (active != null)) {
if ((typeof(active.id) != "undefined") && (active.id != null) && (active.id.length > 0)) {
lastFocus.value = active.id;
}
else if (typeof(active.name) != "undefined") {
lastFocus.value = active.name;

This happens because we have this setup
<collapsible panel>
<iframe>
<script>
</script>
</iframe>
</collapsible panel>
When the page loads, the panel being shown forces the script inside the iframe to be dragged through the DOM before the javascript libraries are loaded. This seems to be a change in that was made for IE9. I have yet to fine a way around this issue but at least I know the cause. A temporary workaround is to force the compatibility of the page to IE8 using a meta tag in case anybody else runs into this issue.
The problem was fixed when I removed the SRC attribute from the iframe and I added onOpen event to jQuery's dialog:
open: function(){
document.getElementById("iframename").src = "page.aspx";
}
