How to simulate tab key with enter key on javascript
提问by sanzy
<script type="text/javascript">
function onDataBound(e) {
$("#batchgrid").on("click", "td", function (e) {
$("input").on("keydown", function (event) {
if (event.keyCode == 13) {
event.keycode=9;
return event.keycode;
}
});
});
}
</script>
here i'm using above script to fire tab key press eventwhen i press the enter key.but it doesn't behave as tab key pressed when i press the enter key.
在这里，我使用上面的脚本在我按下Enter 键时触发Tab 键按下事件。但是当我按下Enter 键时，它的行为不像按下 Tab 键。
please help me here..
请在这里帮助我..

return event.keycodeis effectively return 9, and even return eventwill not help, as returning the event does not mean that will be handled properly, what you probably want to do instead is to take the enterevent and then manually change focus to the next required field:
return event.keycode是有效的return 9，甚至return event无济于事，因为返回事件并不意味着会得到正确处理，您可能想要做的是获取enter事件，然后手动将焦点更改为下一个必填字段：
function onDataBound(e) {
$("#batchgrid").on("click", "td", function (e) {
$("input").on("keydown", function (event) {
event.preventDefault();
if (event.keyCode == 13) {
$(this).next("input, textarea").focus()
}
});
});
}

It will not simulate until you prevent the default enter key event. event.preventDefault(); should be the first command of your function.Then implement the tab key event.Your code should be something like this :
除非您阻止默认的输入键事件，否则它不会模拟。event.preventDefault(); 应该是你的函数的第一个命令。然后实现tab键事件。你的代码应该是这样的：
<script type="text/javascript">
function onDataBound(e) {
$("#batchgrid").on("click", "td", function (e) {
$("input").on("keydown", function (event) {
event.preventDefault();
if (event.keyCode == 13) {
event.keycode=9;
return event.keycode;
}
});
});
}
</script>
Hope it will work.
希望它会起作用。
