I have a view in which I have a kendo-grid, in this grid there is a button to open a detail window. When the button is pressed the detail window opens which is a kendo-window which renders a partial view. When I close the kendo-window I destroy it and set it to null. However I have a JavaScript function on both my view and my partial view that catches the input of a scanner. If I scan while the window with the partial view is open the function on the view does nothing, however when I close the partial view the JavaScript function on the partial view still catches my scans and it tries to process the scan for both pages at once. How can I make sure the partial view is really closed so that it doesn't catch my scan input (preferably with JavaScript).
Partial view action method:
public ActionResult GetKendoWindow(int ID, int PID)
{
//fill and return partial view locationswindow
ViewBag.ID = ID;
ViewBag.PID = PID;
IEnumerable<BinLocationItemModel> model = dbLogic.getItemLocations(PID, ID);
return PartialView("_PartialViewLocation", model);
}
Kendo-window:
function showDetails(e) {
e.preventDefault();
if (wnd) {
wnd.close();
}
var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
wndOpen = 1;
$("#detcont").append("<div id='Details'></div>");
wnd = $("#Details").kendoWindow({
width: "60%",
height: "60%",
actions: ["Minimize", "Maximize", "Close"],
title: "Location Data for: " + dataItem.ArticleID,
content: {
url: "GetKendoWindow",
type: "GET",
data: { ID: dataItem.LineNum, PID: dataItem.PickID }
},
close: function (e) {
wnd.destroy();
wnd = null;
setWindowInactive();
}
}).data("kendoWindow");
wnd.center().open();
}
function setWindowInactive(e) {
wndOpen = 0;
}
Partial View JS:
<script type="text/javascript">
//Scanner opvangen
$(document).ready(function () {
if ($('#ItemLocGrid') != null) {
var pressed = false;
var chars = [];
var grid = $('#ItemLocGrid').data('kendoGrid');
var dataitem = grid.dataItem(grid.select());
$(window).keypress(function (e) {
if (e.which >= 48 && e.which <= 57) {
if (chars.length < 3) {
// do nothing
} else {
$('.focus :input').focus();
}
chars.push(String.fromCharCode(e.which));
}
if (pressed == false) {
setTimeout(function () {
if (chars.length >= 5) {
var barcode = chars.join("");
document.getElementById("txtBarcodes").value = barcode;
$('.focus :input').submit();
}
chars = [];
pressed = false;
document.getElementById("txtBarcodes").value = "";
}, 200);
}
pressed = true;
});
}
});
$('#txtBarcodes').submit(function (e) {
var grid = $("#ItemLocGrid").data("kendoGrid");
var dataSource = $("#ItemLocGrid").data("kendoGrid").dataSource;
var allData = grid.dataSource.data();
var code = this.value;
var notification = $("#notification").data("kendoNotification");
console.log("Nothing to see here");
})
Empty your html inside Details div:
close: function (e) {
. . .
$("#Details").html("");
. . .
}
What is return PartialView("_PartialViewLocation", model); doing, is just returning generated html, from your partial view.
UPDATE
The real problem here is, that you should avoid referencing any scripts in partials. So you need to define a section somewhere in your Layout, for example just before the closing </body>, which will allow views (not partial) to include some custom scripts. Then in the view (not partial) you can override this section to include custom scripts:
#section scripts {
<script src="#Url.Content("~/Scripts/Custom.js")" type="text/javascript"></script>
}
It wasn't exactly like SeM mentioned but his code gave me the idea which fixed it. What I did was put my JavaScript code from my partial view into my view(instead of the layout), I didn't realize my view would be able to read a kendo-grid without actually containing it in its code but it actually can. After that it was just a matter of checking if the window is open and processing a scan for either the partial view or the view.

One of my web app using RichTextBox control from .Net 2.0, the purpose of using it to allow user add/edit content on the fly. This is an old app but it functions as no issue. But since we update DevExpress 16.1 from 14.5 version, things went sour, the app stopped working.
All the icons that using javascript stop working. For example I got undefined value for globalDoc.selection.type
Here is a sample of insert a hyperlink on .cs
//Insert our own custom hyperlink
RichTextBoxControl.ToolbarButton tbInsertLink = new
RichTextBoxControl.ToolbarButton("InsertLink", true);
tbInsertLink.Title = "Insert web address or email link";
tbInsertLink.ClientOnClickFunction = "CustomHyperlink";
RTB_editor.CreateToolbarButton(tbInsertLink);
layoutStr.Append(tbInsertLink.Name);
And below are function on .aspx page. The error starts are globalDoc.selection.type
function CustomHyperlink(editor, htmlmode) {
if (!htmlmode) {
editor.focus();
ShowCustomLinkDialog(editor);
} else {
alert("To use the toolbar, change the HTML view setting");
}
}
function ShowCustomLinkDialog(editor) {
var globalDoc = editor.document;
var rngLink;
var elmLink;
if ("Control" == globalDoc.selection.type) {
RTB_rngMaster = globalDoc.selection.createRange();
if (1 == RTB_rngMaster.length) {
RTB_rngMaster = RTB_getTextRange(RTB_rngMaster(0));
RTB_rngMaster.select();
}
}
if (
"Text" == globalDoc.selection.type ||
"None" == globalDoc.selection.type
) {
RTB_rngMaster = globalDoc.selection.createRange();
//URL is always selected by default
document.all("radioURL").checked = true;
elmLink = RTB_findParentTag("A", RTB_rngMaster);
if (null != elmLink) {
rngLink = RTB_getTextRange(elmLink);
if (rngLink.compareEndPoints("StartToStart", RTB_rngMaster) < 0) {
RTB_rngMaster.setEndPoint("StartToStart", rngLink);
}
if (rngLink.compareEndPoints("EndToEnd", RTB_rngMaster) > 0) {
RTB_rngMaster.setEndPoint("EndToEnd", rngLink);
}
RTB_rngMaster.select();
if ("" != elmLink.href) {
//see what type of link this is
var _linkTxt = elmLink.href;
var _index = _linkTxt.indexOf("mailto:");
if (_index == 0) {
//strip out the mailto from showing
_linkTxt = _linkTxt.substr(7);
document.all("radioEmail").checked = true;
}
document.getElementById("Custom_txtUrl").value = _linkTxt;
} else {
// no href
document.getElementById("Custom_txtUrl").value = "";
}
} else {
//New Selection
document.getElementById("Custom_txtUrl").value = "";
}
RTB_showDialog(editor, CustomLinkDialog, CustomLinkDialogCallback);
document.all("Custom_txtUrl").focus();
}
}
Although on this web page I didn’t use any control any of DevExpress control, but the project as a whole has reference in DevExpress assemblies and use for different applications.
I am not sure why D.E. causes issue to RichTextBox control javascript. Please help!
Thanks

Overview
So I'm trying to take functionality from one part of Squarespace's Galapagos commerce template and add it to another but it's proving to be more difficult than I thought.
I need the image-swapping capability of the "Quick View" (example - mouse over any image and click Quick View ) to replace the column of full sized zoomable images in the "Product View" (example - you see this once you click on a product).
So I found the code for each section:
Product View
This code simply goes through each image in the array and spits it out with the id jsProductItemImages which allows it to be hovered and zoomed.
<div class="productitem-images" id="jsProductItemImages">
{.repeated section items}
{.image?}
<div class="productitem-image-zoom-wrapper sqs-image-zoom-area"><img data-load="false" class="productitem-image loading" {#|image-meta} /></div>
{.end}
{.video?}
{#|video}
{.end}
{.end}
</div>
Quick View
I'm not 100% on the logic here, but essentially it's grabbing the first image and making it a hover/zoomable primary image then listing the entire array of images beneath it as thumbnails. I read that the # symbol is the equivalent of saying this in javascript, but I don't get why it's being used to spit out only the first image in the array.
<figure class="ProductItem-gallery">
{.section items}
<div class="ProductItem-gallery-slides">
{.repeated section #}
{.image?}
<div class="ProductItem-gallery-slides-item" data-slide-index="{#index}"><img class="ProductItem-gallery-slides-item-image" data-load="false" {#|image-meta} /></div>
{.end}
{.video?}
{#|video}
{.end}
{.end}
</div>
{.end}
<div class="ProductItem-gallery-thumbnails">
{.if items.1}{.repeated section items}<div class="ProductItem-gallery-thumbnails-item"><img class="ProductItem-gallery-thumbnails-item-image" data-load="false" {#|image-meta} /></div>{.end}{.end}
</div>
</figure>
Associated JS
First off, it should be noted that I went through and console logged every function to see what was giving the Quick View it's functionality - to no avail. Which is subsequently why I'm here. So it's easy to see where the zoom function is originating: the Product View in the Galapagos.ProductItem function on line 103 $imageContainer = Y.one('#jsProductItemImages');
But I don't see anything out of the ordinary pop up when I look at the Quick View. I've got to be missing something!

My Attempts
My first few attempts have been dropping the jsProductItemImages div from the Product view and dumping in the entire figure block from the Quick View then updating the associated css. While it pulls in the images (I can see them in the inspector and they take up space on the page) it shows up as being blank.
I also tried only using the thumbnails section from the Quick View and limiting the Product View to only show the first image by using {.section items.0} but then any thumbnail I clicked wouldn't swap out without writing the script for it (obviously) but I didn't want to write something like that when I know it exists in the code already!
Any help would be greatly appreciated!
UPDATE:
After replacing the product view markup with the quick view markup I ran into these errors
Uncaught TypeError: Cannot read property 'all' of null site.js:104
init # site.js:104

Unsure why it's hitting an error with .all because it should be addressing the same array of images in both situations?
There's a few questions buried in the this post but let me answer the Quick View question specifically since that's what you're looking to "fix".
Squarespace uses a modular system of JavaScript/CSS add-ons called "rollups". If you pull the source code you'll see a window object that contains the current configuration of any given page. When visiting a Products page, the system triggers the use of their quick view JS and accommodating CSS file. This is where you'll want to be looking. The JS you're digging into is not relevant to Quick View (I don't believe).
Quick View Rollup JS: http://static.squarespace.com/universal/scripts-compressed/product-quick-view-6a1e5642b473ebbb5944-min.js
Quick View Rollup CSS: http://static.squarespace.com/universal/styles-compressed/product-quick-view-eb4b900ac0155bed2f175aa82e2a7c17-min.css
These rollups are triggered off of JavaScript hooks in the template files. What you'll need to do is experiment with using the Galapagos product template word and word so it has the same classes and data-attributes, and see if that works. It would take far too long to cover all of the details of what you need to do without actually working on the project. I would start here first and see if you can setup your product template to triggers the Quick View JS as is, without customization.
I'm using this jQuery script to show search results. Everything works fine, but when search results have more than one page and I'm browsing pages via paging then every page loading is gradually getting slower. Usually first cca 10 pages loads I get quickly, but next are getting avoiding loading delay. Whole website get frozen for a little while (also loader image), but browser is not yet. What should be the problem?
function editResults(def) {
$('.searchResults').html('<p class=\'loader\'><img src=\'images/loader.gif\' /></p>');
var url = def;
var url = url + "&categories=";
// Parse Categories
$('input[name=chCat[]]').each(function() {
if (this.checked == true) {
url = url + this.value + ",";
}
});
url = url + "&sizes=";
// Parse Sizes
$('input[name=chSize[]]').each(function() {
if (this.checked == true) {
url = url + this.value + ",";
}
});
url = url + "&prices=";
// Parse Prices
$('input[name=chPrice[]]').each(function() {
if (this.checked == true) {
url = url + this.value + ",";
}
});
$('.searchResults').load('results.php'+url);
$('.pageLinks').live("click", function() {
var page = this.title;
editResults("?page="+page);
});
}
$(document).ready(function(){
editResults("?page=1");
// Check All Categories
$('input[name=chCat[0]]').click(function() {
check_status = $('input[name=chCat[0]]').attr("checked");
$('input[name=chCat[]]').each(function() {
this.checked = check_status;
});
});
// Check All Sizes
$('input[name=chSize[0]]').click(function() {
check_status = $('input[name=chSize[0]]').attr("checked");
$('input[name=chSize[]]').each(function() {
this.checked = check_status;
});
});
// Edit Results
$('.checkbox').change(function() {
editResults("?page=1");
});
// Change Type
$(".sort").change(function() {
editResults("?page=1&sort="+$(this).val());
});
});
$('.pageLinks').live("click", function() {
var page = this.title;
editResults("?page="+page);
});
just a wild guess but... wouldn't this piece of code add a new event handler to the click event instead reaplacing the old one with a new one? causing the click to call all the once registered handlers.
you should make the event binding just once
var global_var = '1';
function editResults(def) {
// all your code
global_var = 2; // what ever page goes next
};
$(document).ready(function() {
// all your code ...
$('.pageLinks').live("click", function() {
var page = global_var;
editResults("?page="+page);
});
});
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) {

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.
