我已经开始使用jqGrid几天了，一切都运行得很酷。这么好。
与我无关的是，当您单击NavGrid中的编辑按钮而不选择行时，它会显示一个居中的模态弹出窗口，通知没有选择任何行。
但是当你点击添加或编辑（带有选定的行）时，它会在网格的左侧显示一个模态。没有居中。
我想找到一种方法来集中它。
怎么做的？或者它无法开箱即用？

在我看来，最简单的方法是更改beforeShowForm事件内的对话位置：
var grid = $("#list");
grid.jqGrid('navGrid','#pager',
{add:false,del:false,search:false,refresh:false},
{ beforeShowForm: function(form) {
// "editmodlist"
var dlgDiv = $("#editmod" + grid[0].id);
var parentDiv = dlgDiv.parent(); // div#gbox_list
var dlgWidth = dlgDiv.width();
var parentWidth = parentDiv.width();
var dlgHeight = dlgDiv.height();
var parentHeight = parentDiv.height();
// TODO: change parentWidth and parentHeight in case of the grid
// is larger as the browser window
dlgDiv[0].style.top = Math.round((parentHeight-dlgHeight)/2) + "px";
dlgDiv[0].style.left = Math.round((parentWidth-dlgWidth)/2) + "px";
}
});
您可以直观地看到示例here。

出于某种原因，Oleg的代码，如上所列，对我来说并不完全有用（虽然如果没有它，我就不会有这么远）。
两个问题：
1.）如果你只是粘贴在那里，你将移动编辑模式，但不是你的添加模态。我只有一个添加模式，所以这让人困惑了一段时间。你基本上只是double the code（见下文）。
2。）所写的代码是相对于整个页面而不是父div添加平均的顶部和左侧。我确定我错过了一些明显的东西（或者也许这就是TODO的意思？），但这对我有用......
{
beforeShowForm: function(form) {
alert('beforeShowForm FOR EDIT MODAL ONLY');
// cut and paste code below to use for edit modal too.
}
},
// options for add new modal here:
{
beforeShowForm: function(form) {
//alert('adding' + "#editmod" + grdNames[0].id);
var dlgDiv = $("#editmod" + grdNames[0].id);
var parentDiv = dlgDiv.parent(); // div#gbox_list
var dlgWidth = dlgDiv.width();
var parentWidth = parentDiv.width();
var dlgHeight = dlgDiv.height();
var parentHeight = parentDiv.height();
// Grabbed jQuery for grabbing offsets from here:
//https://stackoverflow.com/questions/3170902/select-text-and-then-calculate-its-distance-from-top-with-javascript
var parentTop = parentDiv.offset().top;
var parentLeft = parentDiv.offset().left;
// HINT: change parentWidth and parentHeight in case of the grid
// is larger as the browser window
dlgDiv[0].style.top = Math.round( parentTop + (parentHeight-dlgHeight)/2 ) + "px";
dlgDiv[0].style.left = Math.round( parentLeft + (parentWidth-dlgWidth )/2 ) + "px";
}
}

下面的代码可用于居中窗口。 Oleg示例代码用于此。
如果表格高度发生变化，则不会居中。用于重现表单不是居中问题的测试用例。

Observerd：
视图窗口不居中，底部内容不可见且无法访问。

或只是使用
beforeShowForm: function(form) {$("#editmod" + gridId).addClass("centered"); }
其中gridId是你网格的ID，然后在css中是这样的：
div.centered {
position: fixed;
top: 50%;
left: 50%;
margin-top: -50px;
margin-left: -100px;
}
