function UsersVM(start_page){
var self = this;
console.log('start form ' + start_page);
self.go_to = function(page) {
location.hash = '#Users/' + pageNumber;
}
}
Sammy(function() {
this.get('/app/?#Users/:page', function () {
var vm = new UsersVM(this.params.page);
ko.applyBinding(vm);
});
}).run();
I would like to change the page's hash with the following code:
location.hash = '#Users/' + pageNumber;
But in this case Sammy triggers routing. Say in Backbone we can do it this way:
app.navigate("help/troubleshooting", {trigger: false});
Is it possible to do it in Sammy?
Thanks!
I don't know of a native way to do this in Sammy, but here is a solution that has worked for me:
var sam = $.sammy(function () {
var sammy = this; //get a persistent reference to this
sammy.quiet = false; //set quiet to false by default
//I set quiet to true before running a route
sammy.quietRoute = function (location) {
sammy.quiet = true;
sammy.setLocation(location);
}
//I'm called after every route to reset quiet to false
sammy.after(function () {
sammy.quiet = false;
});
//I'm a 'normal' route that does not have the capability to be 'quiet'
this.get('#normalRoute', function () {
//routing code
});
//I am a route that can be 'quieted' so that when the url or
//hash changes my routing code doesn't run
this.get('#quietableRoute', function () {
if (!sammy.quiet) {
//routing code
} else {
return;
}
});
});
Then call the quietRoute function in your code:
//This will work
sam.quietRoute("#quietableRoute");
//This will not work because the "if(!sammy.quiet)..." code has not been
//implemented on this route
sam.quietRoute("#normalRoute");
Use the following code:
var new_location = '#foo';
app.trigger('redirect', {to: new_location});
app.last_location = ['get', new_location];
app.setLocation(new_location);

I'm stalled with this clicHandler() from this question:
function clickHandler(evt) {
// Activate the circle
activateCircle(evt.target.id);
// Remember which one was clicked, so that we can
// highlight the right one when we get to the subpage
sessionStorage.setItem("selectedMenuId", evt.target.id);
}
The problem is that there are 5 different circles, and I need the clickHandler() to know which one has been clicked and return the correct activateCircle(evt.target.id).
I was thinking about something like this (I might be wrong):
getElementById("c1").onclick = goTransdisciplinary () {
location.href = "/trans-disciplinary";
};
getElementById("c2").onclick = goDatademocracy () {
location.href = "/data-democracy";
};
getElementById("c3").onclick = goCryptography () {
location.href = "/cryptography-and-math";
};
getElementById("c4").onclick = goTranslation () {
location.href = "/translation";
};
getElementById("c5").onclick = goApplication () {
location.href = "/application";
};
But how would a nested function look like?
Trying to convert a lot of jQuery and JS to an Angular controller so that it works the "NG" way. I've looked at the docs and it looks like I can setup a document ready function in Angular using something like angular.element(document).ready to initialize the jQuery variable. What I am confused on is "this" and it's place in the angular world. Anyone have an idea of where to start?
Here is a Pen of what I am trying to accomplish:
CodePen
And I know that there is ng-show/ng-hide and that ngAria shows up around 1.3 but I am just trying to grasp the basis for converting a lot of jQuery to angular.
Here is my current script:
$(document).ready(function() {
var hs1 = new hideShow('open1', 'close1');
var hs2 = new hideShow('open2', 'close2');
var hs3 = new hideShow('open3', 'close3');
var hs4 = new hideShow('open4', 'close4');
});
function hideShow(toggleID, closeID) {
this.$toggle = $('#' + toggleID);
this.$close = $('#' + closeID);
this.$region = $('#' + this.$toggle.attr('aria-controls'));
this.keys = {
enter: 13,
space: 32
};
this.toggleSpeed = 100;
this.bindHandlers();
}
hideShow.prototype.bindHandlers = function() {
var thisObj = this;
this.$toggle.click(function(e) {
thisObj.toggleRegion();
e.stopPropagation();
return false;
});
this.$close.click(function(e) {
thisObj.hideRegion();
e.stopPropagation();
return false;
});
}
hideShow.prototype.hideRegion = function() {
this.$region.hide().attr('aria-expanded', 'false');
this.$toggle.find('span').html('Show');
this.$toggle.focus();
}
hideShow.prototype.toggleRegion = function() {
var thisObj = this;
this.$region.slideToggle(this.toggleSpeed, function() {
if ($(this).attr('aria-expanded') == 'false') { // region is collapsed
$(this).attr('aria-expanded', 'true');
$(this).focus();
thisObj.$toggle.find('span').html('Hide');
} else {
$(this).attr('aria-expanded', 'false');
thisObj.$toggle.find('span').html('Show');
}
});
}
Any suggestions or examples are appreciated.
I am opening mvc view(s) inside a modal dialog.
I am trying to make a recursive call and the problem I am facing is : after the recursive call the view loads properly but none of the controls on the view work :
In Main.js :
$(function () {
$(document).on('click', '.ddlCart li', Mod.Carts);
}
Carts.js :
var Mod = Mod || {};
Mod.Carts = function (e) {
var ddlselectedVal = $(this).attr('id');
var selectedListinsCount = selected_Listings.length;
var SelectedMlsnums = selected_Listings.join();
var agentId = $("#AgentId").val();
var Action;
var EnvironmentURL = $("#EnvironmentURL").val();
var postData = { AgentId: agentId, Mlsnums: SelectedMlsnums, ActionTypeValue: “PreAddToCart” };
var close = function (event, ui) {
$('#dvModalDialog').dialog("close");
}
var open = function (event, ui) {
var url = EnvironmentURL + "MLSReports/Stats/SearchContacts";
$("#btncart_cancel").on("click", function () {
$('#dvModalDialog').dialog("close");
});
$("#btncart_submit").on("click", function () {
var url = EnvironmentURL + "MLSReports/Stats/Cart";
//Send the data using post and put the results in a div
$.post(url, {
AgentId: agentId, Mlsnums: SelectedMlsnums, ActionTypeValue: "AddToCart"
},
function (data) {
// Replace current data with data from the ajax call to the div.
$("#dvModalDialog").empty().append(data);
});
});
$("#lnkCreateNewcart").on("click", function () {
var url = EnvironmentURL + "MLSReports/Stats/Cart";
//Send the data using post and put the results in a div
$.post(url, {
ActionTypeValue: "preAddorEditContact"
},
function (data) {
//debugger;
// Replace current data with data from the ajax call to the div.
$("#dvModalDialog").empty().append(data);
$("#btnCancelContact").on("click", function () {
////********** replace the view (Contact) with the view (Cart).
// In the cancel event I am loading the previous page.I am having problem here. after a recursive call none of the controls work.**
// rd.open();
this.Mod.Carts();
});
});
});
};
if (ddlselectedVal == "AddtoCart") {
var rd = Mod.ReportsDialog({ title: 'Add To Cart', close: close, open: open });
rd.url = EnvironmentURL + "/MLSReports/Stats/Cart";
rd.targetElement = '#dvModalDialog'// '#dvSendEmail'
rd.formName = '#frmCart'
rd.postData = postData
rd.open();
}
};
The value of this inside of the referenced function is going to be different when this.Mod.Carts(); is used. You should use call in this scenario to bind the value of this to the proper value when calling the Carts function.
$("#btnCancelContact").on("click", function () {
Mod.Carts.call(this);
});
I use pjax to ajaxify my menu links. This works fine until I use the browser back button. In my javascript file I use Common Script files (to load all the necessary js files when the user hits the url) and Script files with respect to each menu links (when navigated through pjax)
function myFunction(){
/*All the script files */
}
$(document).ready(function(){
myFunction();
/*pjax menu loading block*/
$(document).on('click', 'a[data-pjax]', function(event) {
$.pjax.click(event, '#pjax-container');
$(document).on('pjax:end', function() {
myFunction();
});
});
});
Now when I navigate to a menu item and try to come back by clicking the browser back button, the script files are getting duplicated (eg: slider images getting duplicated and table sorting not working).How to overcome this issue?
You can implement the url specific loading this way, create a queue of functions which you want to load and unload on pjax complete
The solution is based on js prototyping
// create queue for load and unload
var onLoad = new PjaxExecQueue();
var onUnload = new PjaxExecQueue();
// way to add functions to queue to run on pjax load
onLoad.queue(function() {
someFunction();
});
// way to add functions to queue to unload on pjax load
onUnload.queue(function() {
someOtherFunction();
});
// load function if url contain particular path name
onLoad.queue_for_url(function_name, 'url_section');
// check for url specific function
var URLPjaxQueueElement = function(exec_function, url) {
this.method = exec_function;
if(url) {
this.url = new RegExp(url);
} else {
this.url = /.*/;
}
};
// create a queue object
var PjaxExecQueue = function () {
this.url_exec_queue = [];
this.id_exec_queue = [];
this.fired = false;
this.indicating_loading = false;
this.content = $('#content');
};
PjaxExecQueue.prototype = {
queue: function (exec_function) {
this.url_exec_queue.unshift(new URLPjaxQueueElement(exec_function));
},
queue_for_url: function (exec_function, url_pattern) {
this.url_exec_queue.unshift(new URLPjaxQueueElement(exec_function, url_pattern));
},
queue_if_id_present: function(exec_function, id) {
this.id_exec_queue.unshift(new IDPjaxQueueElement(exec_function, id));
},
fire: function () {
if(this.indicating_loading) {
this.content.removeClass("indicate-loading");
this.indicating_loading = false;
}
if(!this.fired) {
var match_loc = window.location.pathname;
var i = this.url_exec_queue.length;
while(i--) {
this.url_exec_queue[i].fire(match_loc);
}
i = this.id_exec_queue.length;
while(i--) {
this.id_exec_queue[i].fire(match_loc);
}
}
this.fired = true;
},
reset: function() {
this.fired = false;
},
loading: function () {
this.content.addClass("indicate-loading");
this.indicating_loading = true;
this.reset();
},
count: function () {
return exec_queue.length;
},
show: function (for_url) {
for (var i=0; i < exec_queue.length; i++) {
if(for_url) {
if(exec_queue[i].url.test(for_url)) {
console.log("" + exec_queue[i].method);
}
} else{
console.log(exec_queue[i].url + " : " + exec_queue[i].method);
}
}
}
};
// before send
$(document).on('pjax:beforeSend', function() {
onLoad.loading();
onUnload.fire();
});
// after pjax complete
$(document).on('pjax:complete', function() {
onLoad.fire();
onUnload.reset();
});
I'm trying to build a Javascript listener for a small page that uses AJAX to load content based on the anchor in the URL. Looking online, I found and modified a script that uses setInterval() to do this and so far it works fine. However, I have other jQuery elements in the $(document).ready() for special effects for the menus and content. If I use setInterval() no other jQuery effects work. I finagled a way to get it work by including the jQuery effects in the loop for setInterval() like so:
$(document).ready(function() {
var pageScripts = function() {
pageEffects();
pageURL();
}
window.setInterval(pageScripts, 500);
});
var currentAnchor = null;
function pageEffects() {
// Popup Menus
$(".bannerMenu").hover(function() {
$(this).find("ul.bannerSubmenu").slideDown(300).show;
}, function() {
$(this).find("ul.bannerSubmenu").slideUp(400);
});
$(".panel").hover(function() {
$(this).find(".panelContent").fadeIn(200);
}, function() {
$(this).find(".panelContent").fadeOut(300);
});
// REL Links Control
$("a[rel='_blank']").click(function() {
this.target = "_blank";
});
$("a[rel='share']").click(function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
}
function pageURL() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
$.get("loader.php", query, function(data) {
$("#load").fadeIn("fast");
$("#content").fadeOut(100).html(data).fadeIn(500);
$("#load").fadeOut("fast");
});
}
}
This works fine for a while but after a few minutes of the page being loaded, it drags to a near stop in IE and Firefox. I checked the FF Error Console and it comes back with an error "Too many Recursions." Chrome seems to not care and the page continues to run more or less normally despite the amount of time it's been open.
It would seem to me that the pageEffects() call is causing the issue with the recursion, however, any attempts to move it out of the loop breaks them and they cease to work as soon as setInterval makes it first loop.
Any help on this would be greatly appreciated!
I am guessing that the pageEffects need added to the pageURL content.
At the very least this should be more efficient and prevent duplicate handlers
$(document).ready(function() {
pageEffects($('body'));
(function(){
pageURL();
window.setTimeout(arguments.callee, 500);
})();
});
var currentAnchor = null;
function pageEffects(parent) {
// Popup Menus
parent.find(".bannerMenu").each(function() {
$(this).unbind('mouseenter mouseleave');
var proxy = {
subMenu: $(this).find("ul.bannerSubmenu"),
handlerIn: function() {
this.subMenu.slideDown(300).show();
},
handlerOut: function() {
this.subMenu.slideUp(400).hide();
}
};
$(this).hover(proxy.handlerIn, proxy.handlerOut);
});
parent.find(".panel").each(function() {
$(this).unbind('mouseenter mouseleave');
var proxy = {
content: panel.find(".panelContent"),
handlerIn: function() {
this.content.fadeIn(200).show();
},
handlerOut: function() {
this.content.slideUp(400).hide();
}
};
$(this).hover(proxy.handlerIn, proxy.handlerOut);
});
// REL Links Control
parent.find("a[rel='_blank']").each(function() {
$(this).target = "_blank";
});
parent.find("a[rel='share']").click(function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
}
function pageURL() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
var content = $("#content");
$.get("loader.php", query, function(data) {
$("#load").fadeIn("fast");
content.fadeOut(100).html(data).fadeIn(500);
$("#load").fadeOut("fast");
});
pageEffects(content);
}
}
Thanks for the suggestions. I tried a few of them and they still did not lead to the desirable effects. After some cautious testing, I found out what was happening. With jQuery (and presumably Javascript as a whole), whenever an AJAX callback is made, the elements brought in through the callback are not binded to what was originally binded in the document, they must be rebinded. You can either do this by recalling all the jQuery events on a successful callback or by using the .live() event in jQuery's library. I opted for .live() and it works like a charm now and no more recursive errors :D.
$(document).ready(function() {
// Popup Menus
$(".bannerMenu").live("hover", function(event) {
if (event.type == "mouseover") {
$(this).find("ul.bannerSubmenu").slideDown(300);
} else {
$(this).find("ul.bannerSubmenu").slideUp(400);
}
});
// Rollover Content
$(".panel").live("hover", function(event) {
if (event.type == "mouseover") {
$(this).find(".panelContent").fadeIn(200);
} else {
$(this).find(".panelContent").fadeOut(300);
}
});
// HREF Events
$("a[rel='_blank']").live("click", function(event) {
var target = $(this).attr("href");
window.open(target, "_blank");
event.preventDefault();
});
$("a[rel='share']").live("click", function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
setInterval("checkAnchor()", 500);
});
var currentAnchor = null;
function checkAnchor() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
$.get("loader.php", query, function(data) {
$("#load").fadeIn(200);
$("#content").fadeOut(200).html(data).fadeIn(200);
$("#load").fadeOut(200);
});
}
}
Anywho, the page works as intended even in IE (which I rarely check for compatibility). Hopefully, some other newb will learn from my mistakes :p.
