单击确认按钮时删除卡

Question

Please visit the page to see the problem in details https://ibnul.neocities.org/_temporary/au2pr11/au2pr11.html

Here I have 3 cards. Every one of them has a delete button. When clicked it triggers an overlay dialog to cancel or confirm. If I click the cancel it should go away which I have been able to do myself. But If I click the confirm button it should go away and also remove the card which delete button triggered the overlay dialog.

But the overlay dialog is a single one used for all the cards. And also all the cards has the same class name and I also want to keep it that way cause I want to copy paste this multiple time so I don't want to give different class or id name and write different function for each one. How do I detect the element on which the delete icon was clicked and then if user click the confirm button the whole card should disappear? And I want to remove the card by adding a class name called hide-res-card-outer on the res-card-outer element.

Please show it in pure JavaScript.

Answer 1

Based on your comment, I decided to completely start over with my answer. This may not be the best way. Here is a fiddle to see for yourself.

The first thing we do, is create a global object to store our events so we can access them anywhere. This is necessary so we can store which delete button was clicked.

var Event = {};

Next, we capture the event from our show function and store it in the object.

function showDeleteConfBox(event) {
    Event.remove = event;
    del_conf_overlay_box.classList.add('show-del-conf-overl-box');
}

Now inside our remove function, we know exactly which element the event came from so we can traverse to the correct card.

function removeDeleteconfBox() {
    del_conf_overlay_box.classList.remove('show-del-conf-overl-box');
    Event.remove.target.closest('.res-card-outer').classList.add('hide-res-card-outer');
}

We then remove the existing event listener in our cancel function to prevent any of the other cards from being hidden.

function cancelDeleteconfBox() {
    del_conf_overlay_box.classList.remove('show-del-conf-overl-box');
    del_conf_confirm_btn.removeEventListener("click", function() {
        removeDeleteconfBox();
    });
}

Answer 2

I think best practice is to use id's.

But don't worry, if you don't prefer to use id's you can label which card is clicked by adding a class like "toBeRemoved" on the delete button of the card.

You can do this labeling in showDeleteConfBox function by passing button element as parameter.

Then if user confirms removal, find the closest card of labeled button and remove the card.

Then, in either cases (Cancel or Confirm), hide confirmation box and clear the classes "toBeRemoved".

 // These two functions is to find the closest parent of a selector function collectionHas(a, b) { //helper function (see below) for(var i = 0, len = a.length; i < len; i ++) { if(a[i] == b) return true; } return false; } function findParentBySelector(elm, selector) { var all = document.querySelectorAll(selector); var cur = elm.parentNode; while(cur && !collectionHas(all, cur)) { //keep going up until you find a match cur = cur.parentNode; //go up } return cur; //will return null if not found } var delete_menu_btns = document.querySelectorAll('.del-menu-icon-image'); var del_conf_overlay_box = document.querySelector('.del-conf-overl-outer'); var del_conf_cancel_btn = document.querySelector('.del-conf-cancel-btn'); var del_conf_confirm_btn = document.querySelector('.del-conf-confirm-btn'); delete_menu_btns.forEach(btn => { btn.addEventListener('click', function(){ showDeleteConfBox(btn); }); }); function showDeleteConfBox(btn) { del_conf_overlay_box.classList.add('show-del-conf-overl-box'); btn.classList.add('toBeRemoved'); } del_conf_cancel_btn.addEventListener('click', cancelDeleteconfBox); del_conf_confirm_btn.addEventListener('click', removeDeleteconfBox); function cancelDeleteconfBox() { del_conf_overlay_box.classList.remove('show-del-conf-overl-box'); clearBtnClasses(); } function removeDeleteconfBox() { var btnToBeRemoved = document.querySelector('.toBeRemoved'); var cartToBeRemoved = findParentBySelector(btnToBeRemoved, '.res-card-outer'); cartToBeRemoved.classList.add('hide-res-card-outer'); del_conf_overlay_box.classList.remove('show-del-conf-overl-box'); clearBtnClasses(); } function clearBtnClasses() { delete_menu_btns.forEach(btn => { btn.classList.remove('toBeRemoved'); }); }
