Jquery拖放和克隆 [英] Jquery drag /drop and clone
问题描述
我有一套可下载的项目(基本上我是在服装上放下的设计),我正在放弃一个克隆。
如果我不喜欢删除的对象(设计) - 我想通过做一些隐藏的内容来删除它。
但我无法做到这一点。
请帮助我..
这里是代码
var clone;
$(document).ready(function(){
$(。items)。draggable({helper:'clone',cursor:'hand'});
$(。droparea)。droppable({
accept:.items,
hoverClass:'dropareahover',
tolerance:'pointer',
drop:function(ev,ui)
{
var dropElemId = ui.draggable.attr(id);
var dropElem = ui。 draggable.html();
clone = $(dropElem).clone(); //克隆它并保持到jquery对象
clone.id =newId;
clone.css(position,absolute);
clone.css(top,ui.absolutePosition.top);
clone.css(left,ui.absolutePosition.left );
clone.draggable({containment:'parent',cursor:'crosshair'});
$(this).appe nd(clone);
alert(done dragging);
/让我假设我有一个删除按钮,当我点击该克隆应该消失,以便我可以删除另一个设计 - 但以下代码没有影响
//,该项目仍然可见怎么让它消失?
$('#newId')。css(visibility,hidden);
}
});
});
由于.clone()返回一个jQuery对象。 clone.id =newId在jQuery对象上设置一个属性,而不是DOM元素。因为DOM元素没有id属性。 $('#newId')。length应返回null。在firebug控制台中测试
使用:
clone.attr id','newId')
在克隆对象的DOM元素上设置一个ID。 >
Hi I need to achive this ..
I have a set of droppable items ( basically I am droping designs on a apparel ) and I am dropping a clone..
If I don't like the dropped object (designs) - I want to delete that by doing something like hidden .
But I am unable to do that.
Please help me..
here is the code
var clone;
$(document).ready(function(){
$(".items").draggable({helper: 'clone',cursor: 'hand'});
$(".droparea").droppable({
accept: ".items",
hoverClass: 'dropareahover',
tolerance: 'pointer',
drop: function(ev, ui)
{
var dropElemId = ui.draggable.attr("id");
var dropElem = ui.draggable.html();
clone = $(dropElem).clone(); // clone it and hold onto the jquery object
clone.id="newId";
clone.css("position", "absolute");
clone.css("top", ui.absolutePosition.top);
clone.css("left", ui.absolutePosition.left);
clone.draggable({ containment: 'parent' ,cursor: 'crosshair'});
$(this).append(clone);
alert("done dragging ");
/lets assume I have a delete button when I click that clone should dissapear so that I can drop another design - but the following code has no effect
//and the item is still visible , how to make it dissapear ?
$('#newId').css("visibility","hidden");
}
});
});
Since .clone() returns a jQuery object. clone.id="newId" sets an property on the jQuery object not the DOM element. Since the DOM element doesn't have an id property. $('#newId').length should return null. Test in firebug console
Use:
clone.attr('id', 'newId')
to set an ID on the cloned object's DOM element.
