提问by Upvote
I want to convert an number (integer) to a hex string
我想将数字（整数）转换为十六进制字符串
2 (0x02) to "\x02"
or
或者
62 (0x0062) to "\x62"
How can I do that correctly?
我怎样才能正确地做到这一点？

You can use the to string method:
您可以使用 to string 方法：
a = 64;
a.toString(16); // prints "40" which is the hex value
a.toString(8); // prints "100" which is the octal value
a.toString(2); // prints "1000000" which is the binary value

Well, it's seems that you want just to concatenate the integer with \x.
好吧，您似乎只想将整数与 \x 连接起来。
If so just to like that:
如果是这样只是为了喜欢：
var number = 62;
var hexStr = '\x' + number.toString(16);
But you have something strange about explaining.
但是你解释起来有些奇怪。
Note: that 62 is not the same as 0x62, 0x62 would be 98.
注意：62 与 0x62 不同，0x62 将是 98。

var converted = "\x" + number.toString(16)
var converted = "\x" + number.toString(16)
