如何禁用页面滚动,同时拖动jQuery中的可拖动? [英] How to disable page scroll while dragging draggable in jquery?
问题描述
我有一个可拖动的方式定义:
I have a draggable defined this way:
$("#drag_area a").live("mouseup", function() {
var object = $(this);
var class_array = $(this).attr("class").split(" ");
element(object,class_array);
return false;
}).draggable({
containment: "#drag_area",
grid: [44, 44],
zIndex: 1000
}).each(function(i, item){
});
当我拖动类型为'drag_area a'的项目时,如果在拖动页面的同时滚动页面,物品退出遏制......这不是一个渴望的情况,所以我该如何避免这种情况?我可以在拖动过程中禁用页面滚动吗?
When i drag an item of the type 'drag_area a', if i scroll the page while dragging it, the item exits from containment... It is not a desidered situation, so how can i avoid this? Can i disable page scrolling during dragging?
推荐答案
您将使用所有可拖动的元素, em>,即为什么当拖放元素时,整个页面会因拖动而滚动。
You'll be using all your draggable elements without any container, i.e. why when you Drag-n-Drop your elements the whole page scrolls due to dragging.
而不是:
<div class="dragWrapper">
<!-- Place all your draggable elements here -->
</div>
设置 max-height
和<$ dragWrapper
类的c $ c> overflow :
set a max-height
and overflow
of the dragWrapper
class as:
.dragWrapper {
max-height: 400px;
overflow: auto;
}
现在,当您拖放元素,而不是你的 body ,滚动只会在容器内。
Now when you Drag-n-Drop your elements, instead of your body, scroll will be inside the container only.
希望这会为你带来诀窍。 )。
Hope that will do the trick for you(which already did ;).
