如果使用autowidth：true，如何删除自由jqgrid自己的水平滚动条 [英] How to remove free jqgrid own horizontal scrollbar if autowidth:true is used
本文介绍了如果使用autowidth：true，如何删除自由jqgrid自己的水平滚动条的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
使用 jqGrid和自动宽度选项。它如何工作？ answer
autowidth: true,
shrinkToFit: false,
如果jqgrid中有许多行，则出现垂直滚动条，则
这些设置会导致横向滚动条显示在Chrome中，即使所有网格列都适合屏幕。
如何删除这个unececary水平滚动条？只有当列宽的总和大于窗口宽度时才会出现。
If there are many rows in jqgrid so that vertical scrollbar appears, those settings cause horizontal scrollbar to appear in Chrome even if all grid columns fit to screen. How to remove this unnessecary horizontal scrollbar ? It should appear only if sum of column widths is greater that window width.
要重现，请在chrome中打开下面的页面，以便垂直滚动条。
To reproduce, open page below in chrome so that vertical scrollbar appers.
水平滚动条也出现在页面中，但它不应该出现。 < body style =overflow-x：hidden> 不能使用，因为如果需要也禁用滚动条。
Horizontal scrollbar appears then also in page but it should not appear. <body style="overflow-x:hidden"> cannot used since it disables scrollbar also if it is required.

推荐答案
我同意网格宽度的计算在使用 autowidth：true 的情况下不完美。然而，你描述的问题不是一个jqGrid问题。在你发布的演示中，在网格上包含外部div是很好的。它显示了问题的复杂性。
I agree that the calculation of the width of the grid is not perfect in case of usage of autowidth: true. Nevertheless the problem which you describe is not a jqGrid problem. It's good that you included outer div over the grid in the demo which you posted. It shows the complexity of the problem.
首先，在您发布的演示中，它将不显示IE10 / IE11中的水平滚动条。原因是IE默认情况下显示半透明垂直滚动条。因此，它不会在您描述的情况下创建额外的水平滚动条。
First of all it will be displayed no horizontal scroll bar in IE10/IE11 in the demo which you posted. The reason is that IE displays half transparent vertical scrollbar by default. So it's not creates additional horizontal scroll bar in the case which you described.
您可以通过在演示结尾添加以下行来解决问题：
You can fix the problem by adding the following lines at the end of your demo:
if (window.innerWidth > document.documentElement.clientWidth) {
$grid.jqGrid("setGridWidth",
$grid.jqGrid("getGridParam", "width") -
(window.innerWidth - document.documentElement.clientWidth));
}
查看结果这里。
另一方面，演示有外部div在 margin：5px 的网格上。如果我将 margin：5px 更改为 margin：200px ，那么相同的演示将看起来像以下。可以将网格的宽度增加到接近200个额外的像素（精确的最大值是200 - 4，这是我现在不能解释的，但是我可以改进的代码 setGridWidth ）。请参见下一个演示。原因：外部div有 margin-left 和 margin-right 设置为200px，但滚动条<如果我们忽略 margin-right ，则页面上的> 不会存在。它只是边缘，在页面上没有真正的元素。因此，Web浏览器不会在大小写中创建水平滚动条。
On the other side the demo have outer div over the grid with margin:5px. If I change the margin:5px to margin:200px then the same demo will looks as the following. One can increase the width of the grid to almost 200 additional pixel (the exact maximum is 200 - 4, which I can't explain now, but the value can be changed after I improve the code of setGridWidth). See the next demo. The reason: the outer div have both margin-left and margin-right set to 200px, but the scroll bar on the page will not exist if we would ignore the margin-right. It's only the margin and there are exist no real elements on the page in the space. Thus the web browsers don't creates horizontal scroll bars in the case.
