【问题描述】：
我想手动触发 slickgrid 事件。例如：当我按下向下箭头时，我想将当前单元格更改为向下移动。这只有在 slickgrid 处于焦点时才能实现，一旦焦点丢失到网页上，按下向下箭头将不会更改活动单元格。
我试过了：
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>SlickGrid example 1: Basic grid</title>
<link rel="stylesheet" href="mycss/slick.grid.css" type="text/css"/>
<link rel="stylesheet" href="mycss/smoothness/jquery-ui-1.8.16.custom.css" type="text/css"/>
<link rel="stylesheet" href="mycss/examples.css" type="text/css"/>
</head>
<body>
<div>
<p id="p_title"></p>
<p id="p_duration"></p>
<p id="p_Complete"></p>
<p id="p_start"></p>
<p id="p_finish"></p>
<p id="p_effort-driven"></p>
</div>
<table width="100%">
<tr>
<td valign="top" width="50%">
<div id="myGrid" style="width:600px;height:500px;"></div>
</td>
</tr>
</table>
<script src="js/lib/jquery-1.7.min.js"></script>
<script src="js/lib/jquery.event.drag-2.2.js"></script>
<script src="js/slick.core.js"></script>
<script src="js/slick.grid.js"></script>
<script src="js/slick.dataview.js"></script>
<script>
var grid;
var dataView;
var curr_row;
var columns = [
{id: "title", name: "Title", field: "title"},
{id: "duration", name: "Duration", field: "duration"},
{id: "%", name: "% Complete", field: "percentComplete"},
{id: "start", name: "Start", field: "start"},
{id: "finish", name: "Finish", field: "finish"},
{id: "effort-driven", name: "Effort Driven", field: "effortDriven"}
];
var options = {
enableCellNavigation: true,
enableColumnReorder: false
};
$(function () {
var data = [];
for (var i = 0; i < 50; i++) {
data[i] = {
id: i,
title: "Task " + i,
duration: "5 days",
percentComplete: Math.round(Math.random() * 100),
start: "01/01/2009",
finish: "01/05/2009",
effortDriven: (i % 5 == 0)
};
}
dataView = new Slick.Data.DataView();
dataView.setItems(data);
grid = new Slick.Grid("#myGrid", dataView, columns, options);
grid.onKeyDown.subscribe(function (e, args) {
if (e.which == 38) {
curr_row= args.row - 1;
sata(curr_row)
}
if (e.which == 40){
curr_row = args.row + 1;
sata(curr_row)
}
});
grid.onClick.subscribe(function (e, args){
curr_row = args.row;
sata(curr_row)
});
});
function sata(row){
var row_data = dataView.getItem(row); // Read from dataView not the grid data
var cell_contents = row_data['title'];
alert(cell_contents);
}
$(document).keydown(function(e) {
if (e.which == 38) {
curr_row= curr_row - 1;
grid.onClick.notify({row:curr_row})
}
if (e.which == 40){
curr_row = curr_row + 1;
grid.onClick.notify({row:curr_row})
}
});
</script>
</body>
</html>
但是，即使我现在可以获得活动单元格数据，网格也没有更新（渲染未刷新）
任何有关如何使 slickgrid 对此类全球事件做出反应的建议都将受到高度赞赏。提前致谢。
