Question

到目前为止，我有一个容器div，它包含一个按钮，当按钮单击时，它会创建一个div，其id为set =＆＃34; newcard＆＃34;可调整大小（此部分正常工作＆＃39;正确＆＃39;）。但是，当我合并拖动div元素时，根本不拖动。有什么帮助吗？

＆＃13;

$(function(){

	$(".createcard").click(function() {
		var domElement = $('<div id="newcard" ></div>');
		$('.notecard-container').append(domElement);

	});
	$('#newcard').draggable();

});

Answer 1

将draggable()调用移至点击处理程序：

$(function(){

    $(".createcard").click(function() {
        var domElement = $('<div id="newcard" ></div>');
        $('.notecard-container').append(domElement);
        $('#newcard').draggable();
    });

});

Answer 2

您需要在创建元素后添加draggable()。
