This is a simple math game.
My problem: I cannot drag the images in the middle and drag them to the left side. I did some research on the internet but could not find any results.

JS:
function dragstartHandler(e){
e.dataTransfer.setData("text",e.target.id);
}
function dragoverHandler(e){
e.preventDefault();
//e.dataTransfer.dropEffect="copy";
}
function dropHandler(e){
e.preventDefault();
var myData = e.dataTransfer.getData("text");
e.target.appendChild(document.getElementById(myData));
}
Well, your trying to getElementByID but your elements dosent have ID. put ID on your elements.
function dragstartHandler(e){ e.dataTransfer.setData("text",e.target.id); } function dragoverHandler(e){ e.preventDefault(); //e.dataTransfer.dropEffect="copy"; } function dropHandler(e){ e.preventDefault(); var myData = e.dataTransfer.getData("text"); e.target.appendChild(document.getElementById(myData)); }
