SignStatus[(i - 1) / 2] <<= 4;

This line of code shifts the bits in the element of the array "SignStatus" at index (i-1)/2 to the left by 4 positions. This means that the binary representation of the value in that element is shifted 4 places to the left, with the empty spaces on the right being filled with zeros.
For example, if the binary representation of the value in SignStatus[(i-1)/2] is "1100", then after this line of code is executed, it would be "11000000".
The specific purpose of this shift operation depends on the context of the code surrounding it.

let interval = null; interval = setInterval( () => updateUserInfo().then(info => clear(info)), 500 ); const clear = info => info.signStatus && info?.signStep === SIGN_ENUM.SIGN_SCUESS && clearInterval(interval); 以上代码如何设置轮询次数
以上代码是使用 setInterval() 方法来实现轮询的。要设置轮询次数,可以使用一个计数器变量来计算轮询的次数,当达到指定次数后,清除定时器即可。例如,以下代码将最大轮询次数设置为 5:
```
let count = 0;
const maxAttempts = 5;
const interval = setInterval(() => {
updateUserInfo().then(info => {
count++;
if (info.signStatus && info?.signStep === SIGN_ENUM.SIGN_SCUESS) {
clearInterval(interval);
} else if (count === maxAttempts) {
clearInterval(interval);
// 轮询次数达到最大值,做一些处理
}
})
}, 500);
```
在这个例子中,我们使用 count 变量来计算轮询的次数,每次轮询时都将其加 1。当 count 达到最大值(即 maxAttempts)时,清除定时器并做一些处理。当获取到符合条件的结果时,也会清除定时器。
"SignStatus": "未検証",
"SignStatus": "未檢証"通常是指某个签名或身份验证状态尚未经过核实或确认。在这种情况下,可能意味着用户的身份信息、电子文档上的签名或其他在线操作还没有达到正式的认可程度,系统需要进一步处理或请求用户提供额外的信息来完成验证流程。例如,在电子商务网站上,订单可能会显示为“未检証”,表示付款或收货状态还未得到确认。
