可拖动弹出窗口模式窗口溢出问题

Question

我在项目中使用的一个可拖动的弹出模式。但是，当我在这个可拖动的弹出模式上拖动到任何地方时，在浏览器窗口中，我拖动它就会消失。但是，我想要的是这种可持续的弹出模式不会以任何方式在浏览器(窗口(上溢出。 它被锁定在窗口中并显示所有内容。总而言之，我想防止拖动弹出模式滚动打开，并且我还希望它保持在窗口大小内。如果你能帮助我，我会很高兴。

Answer 1

这很容易，你应该看看jqUI draggable知道该怎么做。

使用containment:parent或containment:body

您可以在此处查看许多其他功能

$('.modal').modal({ keyboard: false,
show: true
});
// Jquery draggable
$('.modal-dialog').draggable({
handle: ".modal-header",
containment: "parent"
});
