JQuery UI Sortable - Grab shift when zooming - css

I was trying to use JQuery UI Sortable plugin for multiple tables. The idea was to grab and drop elements in cells of a table, by connecting all <td> tags with this plugin.
It looks like this: https://jsfiddle.net/Lhm3z0bw/3/
By changing zoom with mouse wheel controls, we can actually grab the elements already placed in the table.
However, when the scale is changing, moving them makes a shift on the current grabbed element.
I tried adding some functions from the JQuery UI API for resetting positions for the element or updating the helper, but there's no good results on it.
$(".sortableCards").sortable({
connectWith: ".sortableCards",
containment: "window",
scroll: false,
placeholder: "sortable-placeholder",
items: ".card1",
forcePlaceholderSize: false,
sort: function(evt,ui) {
//////////
// Maybe some fix needed here ?
//////////
}
receive: function(event, ui) {
if ($(ui.sender).hasClass('cards')) {
if ($(this).find('.card1').length > 2) {
$(ui.sender).sortable('cancel');
} else {
ui.item.clone().appendTo($(ui.sender));
}
}
}
});
Here is another linked question with the same issue : How to get JqueryUI Sortable working with Zoom/Scale - mouse movements

cypress can't take screenshot of iFrame and it's elements?

i want to do visual testing with cypress-image-diff. So far, so good. I can take and compare screenshots of the complete page, but never of the element itself, as they are in an iFrame. With help of cypress-iframe I can check e.g. name, stype etc of the element. But screenshots are always taken from another area. Pls help
verifyLogoShown() {
cy.log("Verify if diconium logo is visible");
cy.frameLoaded(this.IFRAME)
// after the frame has loaded, we can use "cy.iframe()"
// to retrieve it
cy.iframe().find(this.TEST_OBJECT).should('have.text', 'Styled Button - primary') // works. I can test all kinds of CSS or other values from the button TEST_OBJECT
cy.wait(1000);
cy.getIframeBody(this.IFRAME).find(this.TEST_OBJECT).should('have.text', "Styled Button - primary")
cy.getIframeBody(this.IFRAME).type("a")
cy.compareSnapshot('button (replaceable)');
//doesn't take screenshot of that part I expect (e.g. iFrame box or button itself, instead of the menu part on the left)
}
My commands.js
Cypress.Commands.add('getIframeDocument', (iFrameSelector) => {
return cy
.get(iFrameSelector)
.its('0.contentDocument');
})
Cypress.Commands.add('getIframeBodyOtherWay', (iFrameSelector) => {
return cy
.getIframeDocument(iFrameSelector).should('exist').its('body').should('not.be.undefined')
.then(cy.wrap);
})
Cypress.Commands.add("getIframeBody", (framename) => {
// get the iframe > document > body
// and retry until the body element is not empty
return cy
.get(framename)
.its('0.contentDocument.body').should('not.be.empty')
// wraps "body" DOM element to allow
// chaining more Cypress commands, like ".find(...)"

.then(cy.wrap);

Fullcalendar event content sticky

im trying to make the content inside of an event in the Fullcalendar sticky. When you scroll in the calendar the content of the events should be visible as long as the event isn't out of the view.
I tried it with simple css but that doesn't work, see for yourself:
.fc-event .fc-content {
position:sticky;
top:0;
}
https://codepen.io/snak3/pen/KZKNMd
Has anyone an idea how to get this working or isn't it that easy?
It's not possible to use position:sticky out of the box, but here's an example of how you might go about it with js (add this to the end of your script):
const content = document.querySelectorAll('.fc-event .fc-content')[1];
const scroller = document.querySelector('.fc-scroller');
scroller.addEventListener("scroll", function() {
if (scroller.scrollTop > 100) {
content.style.position = "fixed";
content.style.top = "130px";
}
else {
content.style.position = "unset";
}
});
Obviously the selector and top values are very specific. You can use js to calculate the appropriate top distance for each event, and apply it for each scroll proc. That is a lot of work though.

resize header not working on DataTable js

I've got a datatable that is responsive, except for the header. The table is initialized according to the code below:
$('.datatable-objects').DataTable({
autoWidth: false,
responsive: true,
scrollX: true,
dom: '<"datatable-header"fl><"datatable-scroll-wrap"t><"datatable-footer"ip>',
language: {
search: '<span>Filter:</span> _INPUT_',
lengthMenu: '<span>Show:</span> _MENU_',
paginate: { 'first': 'First', 'last': 'Last', 'next': '→', 'previous': '←' }
}
});
// Add placeholder to the datatable filter option
$('.dataTables_filter input[type=search]').attr('placeholder','Type to filter...');
// Enable Select2 select for the length option
$('.dataTables_length select').select2({
minimumResultsForSearch: Infinity,
width: 'auto'
});
$('.dataTables_scrollHeadInner').css({"width":"100%"});
$('.datatable-objects').css({"width":"100%"});
$('.datatable-objects').on( 'draw.dt', function () {
$('.dataTables_scrollHeadInner').css({"width":"100%"});
$('.datatable-objects').css({"width":"100%"});
});
});
I need the css hacks at the end in order to make it resize appropriately on window resize. Otherwise, there is a hard size put in the width property and resizing is not working correctly.
I'm not clear on why I need to add this, while in other examples I see there is no need. Anybody a suggestion?
Let's say you have the "tbl-principal" table, then you just need to add as follows:
$('#tbl-principal').dataTable().fnAdjustColumnSizing();
Remarks: if you need to resie on window resize, the code of above needs to be putted on $(window) resize function.
In my case, I´m doing a show/hide div, so... i just put the code on my function...
And that's it... It's working!

Pulling a style from a TinyMCE selection

I'm trying to implement a TinyMCE button that will apply the style of the selection to the entire box. I'm having trouble, though, reading the style of the selection when the selection is buried in a span in a span in a paragraph. Let's consider 'color' for example. Below I have a box with some text and I've selected "here" in the paragraph and made it red.
The HTML for the paragraph is now:
The code behind my button to apply the style of the selection to the box is
var selected_color = $(ed.selection.getNode()).css('color');
console.log("color pulled is ", selected_color);
$(ed.bodyElement).css('color', selected_color);
It doesn't work because the color pulled is black, not red, so the third line just re-applies the black that's already there. (If I replace selected_color in the third line with 'blue' everything goes blue.) So the problem is pulling the color of the current selection.
Does anyone know how I can do this reliably, no matter how buried the selection is?
Thanks for any help.
I also noticed somewhat a strange behavior up and there, with selections of nested span's and div's, but honestly i'm not able to recognize if this is a bug of TinyMCE, a browser issue or a combination of both (most probably).
So, waiting for some more information from you (maybe also your plugin code) in the meanwhile i realized two proposal to achieve what you want: the first plugin behaves like the format painter in word, the second is simply applying the current detected foreground color to the whole paragraph.
As you move throug the editor with the keyboard or mouse, you will see the current detected foreground color highlighted and applied as background to the second plugin button.
Key point here are two functions to get the styles back from the cursor position:
function findStyle(el, attr) {
var styles, style, color;
try {
styles = $(el).attr('style');
if(typeof styles !== typeof undefined && styles !== false) {
styles.split(";").forEach(function(e) {
style = e.split(":");
if($.trim(style[0]) === attr) {
color = $(el).css(attr);
}
});
}
} catch (err) {}
return color;
}
function findForeColor(node) {
var $el = $(node), color;
while ($el.prop("tagName").toUpperCase() != "BODY") {
color = findStyle($el, "color");
if (color) break;
$el = $el.parent();
}
return color;
}
The try...catch block is needed to avoid some occasional errors when a selected text is restyled. If you look at the TinyMCE sorce code you will notice a plenty of timing events, this is a unavoidable and common practice when dealing with styles and css, even more with user interaction. There was a great job done by the authors of TinyMCE to make the editor cross-browser.
You can try out the first plugin in the Fiddle below. The second plugin is simpler as the first one. lastForeColor is determined in ed.on('NodeChange'), so the code in button click is very easy.
tinymce.PluginManager.add('example2', function(ed, url) {
// Add a button that opens a window
ed.addButton('example2', {
text: '',
icon: "apply-forecolor",
onclick: function() {
if(lastForeColor) {
var applyColor = lastForeColor;
ed.execCommand('SelectAll');
ed.fire('SelectionChange');
ed.execCommand('forecolor', false, applyColor);
ed.selection.collapse(false);
ed.fire('SelectionChange');
}
return false;
}
});
});
Moreover: i think there is a potential issue with your piece of code here:
$(ed.bodyElement).css('color', selected_color);
i guess the style should be applied in a different way, so in my example i'm using standard TinyMCE commands to apply the foreground color to all, as i wasn't able to exactly convert your screenshot to code. Please share your thoughts in a comment.
Fiddle with both plugins: https://jsfiddle.net/ufp0Lvow/
deblocker,
Amazing work! Thank you!
Your jsfiddle did the trick. I replaced the HTML with what was in my example and changed the selector in tinymce.init from a textarea to a div and it pulls the color out perfectly from my example. The modified jsfiddle is at https://jsfiddle.net/79r3vkyq/3/ . I'll be studying and learning from your code for a long time.
Regarding your question about
$(ed.bodyElement).css('color', selected_color);
the divs I attach tinymce to all have ids and the one the editor is currently attached to is reported in ed.bodyElement. I haven't had any trouble using this but I have no problem using your
ed.execCommand('SelectAll');
ed.fire('SelectionChange');
ed.execCommand('forecolor', false, applyColor);
Thanks again! Great job!

Summernote has uneditable inputs in modals with dialogsInBody

I have one instance of summnernote in jQuery UI dialog.
By default all summernote's modals look like this:
But when I remove <div class="modal-backdrop in"></div>, I can write into all inputs in these modals:
Well, I've found a solution with dialogsInBody:
$('someTarget').summernote({
dialogsInBody: true,
... //another options
});
But when I turn it on, all text inputs inside the summernote's modals are uneditable! I can interact with checkboxes and file inputs, even the cursor changes to "text", but I am not allowed to write anything into text inputs:
I've inspected, there aren't any blocks over them. And I can't find any extra styles to block inputs (e.g. like pointer-events).
What does exactly do option dialogsInBody? Why inputs aren't editable?
Ok, I've resolved this problem by myself.
There are details:
In summernote.js there are such usage of dialogsInBody:
var $container = options.dialogsInBody ? $(document.body) : $editor;
Therefore modal window appends itself to body (instead summernote editor) when we set {dialogsInBody:true}. Nothing else.
Jquery UI Dialog has a behavior that blocks all text inputs outside of itself (see this). So when summernote is opened inside ui-dialog all of its modals has uneditable inputs.
My solution is to exclude all inputs in summernote modals from list of disallowed items. it required to override a dialog method _allowInteraction:
//fix problem that block inputs in modal dialog outside main UI Dialog
if ($.ui.dialog.prototype._allowInteraction) {
var originalAllowInteraction = $.ui.dialog.prototype._allowInteraction;
$.ui.dialog.prototype._allowInteraction = function(e) {
var isInModal = $(e.target).closest('.modal-dialog').length > 0;
return isInModal || originalAllowInteraction(e);
};
}
