我想为我的网格添加快捷键。如何分配新的Alt + a。

谢谢

我尝试过：



我尝试将功能键F1作为112 ascii代码。

解决方案

ALT + A没有ASCII码（但是keyCode是18），只有A有一个ASCII代码，您将仅针对该代码进行测试。但是，您还将测试用户是否也按下了ALT键。



我建议将事件处理程序附加到HTML文档（或以非常推荐的方式，附加到body元素），然后使用JavaScript处理它。所以，为此，试试这个：

（ document ）。ready（ function （）{

（' body'）。keydown（ function （）{
if （ window .event.altKey == true &&& class =code-sdkkeyword> window .event.keyCode == 65 ）{
document .getElementById（ landing）。innerText = Alt + A已按下。;
} else {
document .getElementById（ landing）。innerText = Alt +未组合。;
}
}）;
}）;

这也可以在编辑小提琴中进行测试 - JSFiddle [ ^ ]。您现在还可以根据需要为键添加更多组合。

Hi,

I want to add shortcut key for my grid. How to assign for new Alt+a.

What is the ascii key for Alt+a

Thanks

What I have tried:

I tried function key F1 as 112 ascii code.

解决方案

ALT + A has no ASCII code (but the keyCode is 18), only A has an ASCII code and you will be testing against that one only. However, you will also be testing if the ALT key is also pressed by the user.

I would recommend attaching an event handler to the HTML document (or in a much recommended way, to the body element) and then handle it using JavaScript. So, for that just try this:

(document).ready(function () {

('body').keydown(function () { if(window.event.altKey == true && window.event.keyCode == 65) { document.getElementById("landing").innerText = "Alt + A pressed."; } else { document.getElementById("landing").innerText = "Alt + A combination not made."; } }); });

This can also be tested at, Edit fiddle - JSFiddle[^]. You can now also add more combinations for the keys as per they are needed.
