How to programmatically select top row of JQGrid?
提问by MikeD
How does one programmatically select the top row of a JQGrid. I want to have the top row already selected when it is opened on the page. My grid is sorted by a descriptive column so the first row's id could be any number. I know the method to use I just don't know how to get the rowid for the top (first) row. The method is:
如何以编程方式选择 JQGrid 的第一行。我希望在页面上打开时已经选择了顶行。我的网格按描述性列排序，因此第一行的 id 可以是任何数字。我知道使用的方法我只是不知道如何获取顶（第一）行的 rowid。方法是：
jQuery("#mygrid").setSelection(rowid, true);

Or, without using the jqGrid API, you should be able to retrieve the top row by navigating the DOM:
或者，不使用 jqGrid API，您应该能够通过导航 DOM 来检索顶行：
var top_rowid = $('#mygrid tbody:first-child tr:first').attr('id');

The answer above was close, but the case was off. It should be:
上面的答案很接近，但案子已经结束。它应该是：
$("#mygrid").getDataIDs()[0];
That should work properly.
那应该可以正常工作。

jqGrid supports a setSelectionmethod it just needs to be called correctly:
jqGrid 支持一种setSelection只需要正确调用的方法：
var grid = jQuery("#mygrid"),
ids = grid.jqGrid("getDataIDs");
if(ids && ids.length > 0)
grid.jqGrid("setSelection", ids[0]);

I've used the following:
我使用了以下内容：
var grid = $('#list');
grid.jqGrid({
...
gridComplete: function() {
var ids = grid.jqGrid("getDataIDs");
if(ids.length > 0) {
grid.jqGrid("setSelection", ids[0]);
}
},
...
});

If you have header row try this :
如果你有标题行试试这个：
$('#tb_par tbody:first-child tr:nth-child(2)').trigger("click");
$('#tb_par tbody:first-child tr:nth-child(2)').trigger("click");
If not than :
如果不是：
$('#mygrid tbody:first-child tr:first').trigger("click");
$('#mygrid tbody:first-child tr:first').trigger("click");
It will directly trigger click event of the JqGrid.
它会直接触发 JqGrid 的点击事件。
