JQuery UI可选插件：当div溢出时，滚动条不可选 [英] JQuery UI Selectable plugin: Make scroll bar not selectable when div overflows

问题描述

我有一个div设置为 overflow：auto; 。这个div的内容是可选择的（使用jQuery UI）。

I have a div that's set to overflow: auto;. This contents of this div are selectable (using jQuery UI).

当div溢出并出现滚动条时，滚动条本身变得可选，因此滚动效果不佳。在FF / Chrome中，我可以滚动div但是我得到了可选择的轮廓。在Safari中，滚动条根本不会参与，因为可选择的处理程序会选择点击。

When the div overflows and a scrollbar appears, the scrollbar itself becomes selectable so scrolling doesn't work well. In FF/Chrome, I can scroll the div but I get the selectable outline. In Safari, the scroll bar won't engage at all since the click is picked up by selectable's handler.

我是否可以使用选择器将滚动条添加到'取消'项目清单？或者其他任何阻止滚动条可供选择的方法？

Is there a selector I can use to add the scrollbar to the 'cancel' items list? Or any other way to prevent the scroll bar from being selectable?

这是我如何配置可选div的代码片段：

Here's a code snippet of how I'm configuring my selectable div:

$(".mySelectable").selectable( {
    cancel: '.myButton, .notSelectable',
    filter: '.rowSelectable',
    selecting: function(event, ui){
        handleSelection(ui.selecting);
    },
    selected: function(event, ui) {
        handleSelected(ui.selected);
    },
    unselected: function(event, ui) {
        handleUnselected(ui.unselected);
    }
});

我的HTML看起来像：

My HTML looks like:

<div class="mySelectable"> <!-- set to auto overflow -->
    <div class="myButton">I can't be selected</div>
    <div class="rowSelectable">I am a selectable row</div>
    ...
</div>

理想情况下，我正在寻找可以添加到'cancel'选项的内容，这有助于跳过滚动条。

Ideally, I'm looking for something that I can add to the 'cancel' option which helps skip the scroll bar.

推荐答案

D'哦！解决方案很简单 - 添加另一个div而不是它的溢出设置。
因此，html变为：

D'oh! Solution was simple -- add another div and not have it's overflow set. So, the html becomes:

    <div class="wrapperDiv"> <!-- set to auto overflow -->
        <div class="mySelectable"> <!-- NOT set to overflow -->
            <div class="myButton">I can't be selected</div>
            <div class="rowSelectable">I am a selectable row</div>
            ...
        </div>
    </div>
