Answer 1

首先在你的案例中选择你的容器对象是draggable1，然后从容器中选择子项并根据索引删除

$("#draggable1").children().remove();

- ＆GT;但这将删除所有孩子

或者您可以选择过滤子项

$("draggable1").children(":contains('sometext')").remove();

或使用子索引的子对象中的另一个过滤器

$("draggable1").children(":nth-child(0)").remove();

Answer 2

我看到你正在使用jQuery ......

$('#idImageElement').click(function(){

    $('.classElementsToRemove').remove();

});
