I'm trying to select an item in a DOM draggable list so that I can move it to another field with a button. Is there a mouseDown
or similar function to mark the selected item?
var nmbrCustomers = 10; // Enter the number of customers!
var customerArray = new Array(nmbrCustomers);
for (var i = 1;i < nmbrCustomers + 1; i++){
customerArray[i] = "f_" + i
}
customerArray.forEach(myFunc);
function myFunc(item,index){
console.log(document.getElementById(item).innterHTML);
}
With this code I can reach all the elements I want, but I don't know how to make them selected/marked. The results from the above code gives the following code for each element:
<td class="menuGroup" nowrap="nowrap">
<img id="someimageID" class="navigatorGroupImage" align="left"
src="someimageDir" onclick="toggleGroup(9)"
ondragstart="dragStartGroupIcon(event)" alt="Alternar expandir/colapsar">
<span id="someID"
class="navigatorGroupText" draggable="true"
onmousedown="mouseDownGroup('f_9', Event.extend(event))"
onmouseup="mouseUpGroup('f_9', Event.extend(event))"
onmousemove="mouseMoveGroup('f_9', Event.extend(event))"
title="someName.">
</span>
</td>
You can dynamically add and remove a CSS class to the dragged element. The following code snippet will work if you add a draggable
CSS class to the elements you want to drag - change the CSS rule to suit your requirements.
let sources = document.querySelectorAll('.draggable'); sources.forEach(source => { source.addEventListener('dragstart', dragStart); source.addEventListener('dragend', dragEnd); }); function dragStart(e) { // Add a 'dragging' CSS class to the element this.classList.add('dragging'); } function dragEnd(e) { // Remove the 'dragging' CSS class this.classList.remove('dragging'); }
.dragging { opacity: .50; border: 6px solid #000; }
