我正在尝试“刷新”或“重新加载”网格，并在网格重新加载后保留有焦点的行。
我试过这样做： -
var rowId = $("#dispatch").jqGrid('getGridParam','selrow');
var thisRow = (parseInt(rowId) + parseInt(1));
$("#dispatch").trigger("reloadGrid");
setTimeout(function(){
$("#dispatch").setSelection(thisRow);
}, 151);
但你可以从位置＃1到新位置看到它。
还有其他方法可以重新加载网格并保持焦点位置吗？
尝试： -
// Display Current Jobs
$('#btn-current').bind('click', function() {
$.ajax({
type: 'GET',
url: 'scripts/php/jobs.controller.php',
data: "id=" + "current",
success: function(data){
allButtons.removeClass('active');
$('#btn-current').addClass('active');
$("#dispatch").trigger("reloadGrid", [{current:true}]);
}
});
});
网格： -
$(function () {
var lastsel2
var rowsToColor = [];

答案 0 :(得分：2)
您需要使用setSelection：setTimeout的其他参数，而不是在reloadGrid内使用current:true。有关详细信息，请参阅the answer。
更新：gridComplete的代码似乎是您遇到问题的原因：
$("#dispatch").setSelection(0, true);
重新加载到id="0"的行后，它会重置网格的选择。
我强烈建议您将loadComplete的代码替换为更有效的rowattr回调。有关相应的代码示例，请参阅the answer。
此外，您不应在每行选择上绑定$('body').keyup。在您绑定（注册）越来越多的新keyup事件句柄的方式中，而不解除前一个。我不确定您要在代码部分中执行什么操作，但您可能应该将代码移到<{1}}回调的之外。
创建网格后，我没有看到任何理由设置onSelectRow ondblClickRow。相反，您可以在创建网格期间直接在jqGrid选项列表中包含setGridParam回调（就像您定义了ondblClickRow，loadComplete和onSelectRow回调一样）。
我建议您在任何jqGrid回调中使用gridComplete而不是$(this)。
