As the title says. I want to make a list of div elements inside a div. I want to be able to scroll the list up and down, and when the list is not scrolling anymore, i want to be able to click the listed elements do to something. I cant figure out how to do this.
the touchmove event executes whenever the user touches the div, even if the div its scrolling. THen i cant figure out how to make let the program know that the div isnt scrolling anymore, so the next touch on the elements will trigger a non scrollable event.....
EDIT:
what i have so far is this... However this is a quick "fix" and its not working as intended. For example if you scroll quickly up and down, then the div will think you pressed on one of the elements..
exerciseWrapper is the elements inside the scrolling div. Each element is wrapped around exerciseWrapper.
$('.exerciseWrapper').on('touchstart',function(){
touchstart=true;
setTimeout(function(){
touchstart=false;
}, 100);
});
$('.exerciseWrapper').on('touchend',function(){
if(touchstart)
{
$('.exerciseWrapper').not(this).css('border-color','black');
$(this).css('border-color','orange');
}
});
Ok so i finally figured this one out.. Reason why i couldnt wrap my minds around the solution on this, was because i couldnt get other events then eventstart and event end to work... At the time of writing i still cant get the other events like eventcancel and eventleave to work. However eventmove works and i solved the problem using this event. eventmove keeps updating the element its linked when you move your finger. Then i had a variable of touchmove to constantly be true if i am scrolling my div (with touchmove event). WHen i stop moving i can clik on selected element again and use a normal eventstart event.. This is my working code:
var touchmove=false;
function AddExercisesEvents()
{
$('#exerciseMenu').on('touchmove',function(){
touchstart=true;
$('h1').text("move");
});
$('.exerciseWrapper').on('touchend mouseup',function(event){
event.stopPropagation();
event.preventDefault();
// $('.exerciseWrapper').off();
if(event.handled !== true)
{
touchstart=false;
//ENTERING editExercise Menu..!
if(!touchstart)
{
//insert magic here
alert($(this).attr('id'));
}
}
return false;
});
}

I'm using a Kendo ScrollView to display person images on a form.
Separate from the ScrollView, users can change the display order of the images. After they save their changes to the display order, the ScrollView is reloaded, scrolls to the first item, and should display the images in their new order.
However, I've noticed that when the ScrollView is currently on the first page, that page does not get refreshed/redrawn.
My ScrollView looks something like this:
#(Html.Kendo().ScrollView()
.Name("personImage")
.TemplateId("personImageTemplate")
.DataSource(d => d
.Custom()
.Type("aspnetmvc-ajax")
.Transport(t => t
.Read(r => r.Action("PersonImages_Read", "Person", new { personID = Model.ID } ))
)
.Schema(s => s.Data("Data").Total("Total"))
.ServerPaging(false)
.PageSize(1)
)
)
The template looks like this:
<script type="text/x-kendo-tmpl" id="personImageTemplate">
<img class="personImage"
src="#(Url.Action("ImageRender", "Person"))?imageID=#= data.ID #"
title="#= data.Filename #" />
</script>
And here is my refresh function:
function refreshPersonImageScrollView() {
var scrollView = $("#personImage").data("kendoScrollView");
if (scrollView) {
scrollView.dataSource.read();
// https://docs.telerik.com/kendo-ui/api/javascript/ui/scrollview/methods/refresh
// redraws, doesn't re-read from datasource
scrollView.refresh();
// scroll to first image
scrollView.scrollTo(0);
}
}
When I watch the requests being made when I call this function, I see this:
A. When a page other than the first page is selected:
PersonImages_Read (the ScrollView's dataSource read)
The ScrollView scrolls to the first image
3x ImageRender, as it renders the first 3 items in the ScrollView
B. When the first page is selected:
PersonImages_Read (the ScrollView's dataSource read)
Nothing else
I tried switching the order of scrollView.refresh() and scrollView.scrollTo(0), but the result does not change.
Is there any way to get Kendo to refresh/redraw the current page? I thought refresh would do it, based on the documentation, but it does not.
Edit
I've been able to replicate this issue in REPL. To see the behavior in action:
Note the "Rendered" time under the first image.
Scroll to the second image in the ScrollView.
Wait several seconds, then click the "Refresh" button.
The ScrollView should scroll back to the first image.
Observe that the "Rendered" time under the first image matches the "Last clicked" time reported below the "Refresh" button, and is no longer what it was in step #1. (This is the correct behavior.)
Remain on the first image for several seconds. Note the "Rendered" time listed before continuing.
Click the "Refresh" button.
Note that the "Last clicked" time has updated, and in the "Log" section, there is an entry that reads "dataSource read complete" at approx. the same time. However, the "Rendered" time under the image has not changed, and there is no log entry that says "image for product #X loaded".
I am using Kendo version 2021.3.1109 in my project. The Kendo version in the REPL above is 2022.3.913 and it still occurs in that version.
I have found a way to resolve the issue, but this may be worth opening a possible bug ticket with Telerik, because you would think that scrollView.refresh call would work.
What I changed in your refreshPersonImageScrollview function was to call setDataSource on the scrollview rather than calling the refresh method. Like so:
function refreshPersonImageScrollView() {
$("#refresh-last-clicked").text("Last clicked: " + getCurrentTime());
addToLog("refresh button clicked");
var scrollView = $("#personImage").data("kendoScrollView");
if (scrollView) {
scrollView.dataSource.read();
scrollView.setDataSource(scrollView.dataSource);
// scroll to first image
scrollView.scrollTo(0);
}
}
This appears to force the scrollView to re-evaluate its life choices and properly refresh :) However, it does seem to trigger additional dataSource reads, so it's not ideal.
One other thing I tried that didn't resolve the problem, but may be a good thing to change to anyway, would be to utilize the promise returned by the dataSource.read call. Meaning, do your scrollView setDataSource and scrollTo calls after the dataSource read promise is settled, like so:
scrollView.dataSource.read().then(function() {
scrollView.setDataSource(scrollView.dataSource);
// scroll to first image
scrollView.scrollTo(0);
});

hi everyone here is my test page so you can see what help that i need,
http://jjvirgin.24techstuddev.com/testpage/
i want to continues slide left or right when hover, cause at the moment its only sliding left or right once. i want to make it continue sliding to left when you hover on the left button, or continue sliding to the right when you hover to the right button.
here is the code that i used to make it slide once.
<script>
jQuery(document).ready(function() {
jQuery('.slick-prev').mouseover(function() {
jQuery('.swiper-wrapper').slick('slickPrev')
});
jQuery('.slick-next').mouseover(function() {
jQuery('.swiper-wrapper').slick('slickNext')
});
});
</script>
Instead ou using 'slickPrev' and 'slickNext' methods use slickPlay on mouseover() and slickPause on mouseout()
Currently I have a page which on load scatters draggable divs randomly over a page using math.random
Using media queries however the page uses packery to display the same images for browser widths under 769px in a grided fashion.
I had the idea that it could be interesting to create a 'sort/organize' button which would rearrange these divs using packery and remove the draggable class already applied, however i have no idea if this is possible or how to go about it. If there is any method of animating this process that would also be a bonus!
If anyone could at the very least point me in the right direction i would be extremely thankful!!
Hopefully this gives you a bit of a starting point.
I would read up on JQuery as it has some useful helpers for DOM manipulation.
I don't think this is the most efficient way to do it, and I think you will need to rethink your test harness for doing this in the future, but hopefully this gets you started.
Firstly I've added a button to trigger the sort
<div class="rotate" id="contact">Contact</div>
<div id="logo">Andrew Ireland</div>
<button id="sort">sort</button>
Then updated the script to override the css setting to switch between draggable view and item view.
// general wait for jquery syntax
$(function(){
// trigger the layour to sort get the packery container
var container = document.querySelector('#container.packery');
var pckry = new Packery( container );
//button function
$("#sort").click(function(){
//Hide all the dragged divs
//ui-helper-hidden is a jquery ui hider class
if($('.box').css('display') == 'block') {
$('.box').css({'display':'none'});
//Show all the item class's
$('.item').css({'display':'block'});
//show the container
$('#container').css({'display':'block'});
// trigger the layour to sort
pckry.layout();
} else {
//hide all the item class's
$('.item').css({'display':'none'});
//hide the container
$('#container').css({'display':'none'});
//show the draggable box's
$('.box').css({'display':'block'});
}
});
$( ".pstn" ).draggable({ scroll: false });
$(".pstn").each(function(i,el){
var tLeft = Math.floor(Math.random()*1000),
tTop = Math.floor(Math.random()*1000);
$(el).css({position:'absolute', left: tLeft, top: tTop});
});
});
As I said this is more to get started. The packery documentation details how to trigger its layout functions so another approach would be to only have the draggable elements, and put these inside a packery container. Then when you want to sort them you can just trigger that the packery.layout() function.
I hope this is helpful, I am only just getting started on stack overflow so any feedback would be appreciated.
When editing my grid, if I click outside the grid, the box I was editing is still editable. How do I get the edited cell to "complete" the edit when it looses focus?
The following code will save the current edit.
Slick.GlobalEditorLock.commitCurrentEdit();
You'll need to place this inside an event handler that you think should trigger the save. For example, if you're using the sample text editor plugin, I believe an editor-text CSS class is added to the input field that's created when you're editing a cell so something like this should work:
$('#myGrid').on('blur', 'input.editor-text', function() {
Slick.GlobalEditorLock.commitCurrentEdit();
});
I found that I needed to wrap clav's handler in a timeout:
$("#myGrid").on('blur', 'input.editor-text', function() {
window.setTimeout(function() {
if (Slick.GlobalEditorLock.isActive())
Slick.GlobalEditorLock.commitCurrentEdit();
});
});
to avoid errors like:
Uncaught NotFoundError: An attempt was made to reference a Node in a context where it does not exist.
when using the keyboard to navigate. Presumably the new blur handler fires before SlickGrid can do its own handling and this causes problems.
Unfortunately, probably due to differences in event processing, Grame's version breaks keyboard navigation in chrome.
To fix this, I added another check to only commit the edit, if the newly focused element is not another editor element within the grid (as the result of keyboard navigation):
$('#grid').on('blur.editorFocusLost', 'input.editor-text', function() {
window.setTimeout(function() {
var focusedEditor = $("#grid :focus");
if (focusedEditor.length == 0 && Slick.GlobalEditorLock.isActive()) {
Slick.GlobalEditorLock.commitCurrentEdit();
}
});
});
This seems to work in current versions of firefox, chrome and ie.
I have a really annoying issue with Autocomplete with Prototype 1.6. I set up and dialog-style div with a form, which contains an Autocomplete. Everything works fine until I click the scroll bar, or drag it; it closes the list of suggestions. I checked this solution but now I got an javascript error
event.srcElement is undefined
I was checking the controls.js and tried to catch the event object inside the onBlur event, but it travels empty. Printed the offsetX property and is undefined. Looks like the event doesn't exist anymore. either way, it prevents that the list closes but, If I click outside the area, the list now doesn't close. And that's kinda of issue too
Anyone with this same issue? Any idea?
Thanks in advance
I was having the exact issue yesterday, but after doing some r&d I got a pretty handy fix for this.
By default this script was hiding the result div (Suggestion List) on the blur event on the search text box so as soon as we click on result div's scroll bar focus gets lost from input element & result div closes. So I did a small edit in controls.js to change the behavior of script, so now result div close method doesn't invoke on blur (focus out) from input element but triggered on the click on the document except the text input element.
For your convenience I've put the edited controls.js here.
If you like to know what has changed in JS file, here it is;
Added a event listener to the document. Just below this line
"Event.observe(this.update, "keypress", this.onKeyPress.bindAsEventListener(this));"
Event.observe($(document), "mouseup", this.onMouseup.bindAsEventListener(this));
Added a new onMouseup method.
onMouseup: function(event) {
if(!this.hasFocus) {
this.hideTimeout = setTimeout(this.hide.bind(this), 250);
this.hasFocus = false;
this.active = false;
}
},
Modify the onBlur method (Comment out two line in block)
onBlur: function(event) {
//this.hideTimeout = setTimeout(this.hide.bind(this), 250);
//this.active = false;
this.hasFocus = false;
}
I hope this will solve your issue.
Thanks
