JQGrid - 垂直滚动不适用于冻结列

JQGrid - Vertical scroll not working on Frozen columns

我有一个超过 20 列的 JQGrid。所以我将前 3 列保持为冻结状态,并且网格没有分页。因此,根据要求,我们添加了主要 div 的高度,以便用户可以滚动 up/down。现在,在添加冻结列后,滚动会出现在网格的右侧,并且当鼠标在任何未冻结的列上滚动时它会起作用。但是当我尝试将鼠标滚动到冻结的列上时,滚动不起作用。将感谢任何 clue/solution.

如果我正确理解了问题,那么您需要在冻结列上使用鼠标滚轮。执行此操作,您可以在 调用 setFrozenColumns:

的某处添加以下代码
$($grid[0].grid.fbDiv).bind("mousewheel DOMMouseScroll", function (e) {
    $grid[0].grid.bDiv.scrollTop -= e.type === "mousewheel" ?
        e.originalEvent.wheelDelta / 10 :
        -e.originalEvent.detail * 6;
});

它应该可以工作,但我确信 delta 的值的计算应该得到改进。我会考虑在 setFrozenColumns 的主要代码中进行更改以自动执行相同的操作(在免费的 jqGrid 代码中)。

在您的页面上添加以下样式,这对我很有用。

.frozen-bdiv {
    pointer-events: none;
}
