How to simulate a key press for 5 seconds on the keyboard using TestCafe
问题
I tried to send it to the browser console by pressing .pressKey("PageDown"), after tracking it, but nothing came of it. Who can tell what steps to take next, maybe there are examples? I was told that you can use the clientfunction, but I can't understand how to put it all together due to the lack of the same examples. The attempted code is below:
await t
.click(S(sCounter))
.pressKey("PageDown");
await t.eval(() => {
document.addEventListener("keydown", function (event) {
console.log(event.key);
if (event.key === "PageDown") {
console.log("PageDown press");
let isKeyPressed = false;
let timeoutId = null;
isKeyPressed = true;
timeoutId = setTimeout(() => {
isKeyPressed = false;
if (timeoutId !== null) {
clearTimeout(timeoutId);
}
}, 10 * 1000); // set the timeout to the specified number of seconds
}
console.log("PageDown Up");
});
});

t.pressKey 操作模拟一系列的 "keydown"、"keypress" 和 "keyup" 事件。要模拟按住键，您可以使用 t.dispatchEvent 操作。以下是其使用示例：https://github.com/DevExpress/testcafe/issues/1839#issuecomment-1506640783。
此外，根据您的代码片段，您需要在操作发生之前添加一个事件侦听器。将 t.eval 调用放在 click 和 pressKey 上方。
英文:
The t.pressKey action simulates a sequence of "keydown", "keypress", and "keyup" events. To simulate holding a key, you can use the t.dispatchEvent action. Here is an example of its usage: https://github.com/DevExpress/testcafe/issues/1839#issuecomment-1506640783.
Also, according to your code snippet, you need to add an event listener before the action occurs. Place the t.eval call above click and pressKey.
