Uncaught TypeError: Cannot read property 'parentNode' of null javascript
提问by Kepedizer
This code should make an element disappear from a list when it is dropped on another element (called cookiemonster)
当一个元素被放到另一个元素（称为 cookiemonster）上时，此代码应该使该元素从列表中消失
addEvent(cookiemonster, 'drop', function (e) {
if (e.stopPropagation) e.stopPropagation();
var el = document.getElementById(e.dataTransfer.getData('text'));
el.parentNode.removeChild(el);
return false;
});
采纳答案by eventHandler
create an auxiliar variable like this
创建一个像这样的辅助变量
addEvent(cookiemonster, 'drop', function (e) {
if (e.stopPropagation) e.stopPropagation();
var el = document.getElementById(e.dataTransfer.getData('text'));
var aux = el.parentNode;
aux.removeChild(el);
return false;
});
