JavaScript为数字在左边自动补0的函数 leftZeroPad,例如:leftZeroPad(3, 2) 将返回 03 var MANY_ZEROS = "000000000000000000"; function leftZeroPad(val, minLength) { if (typeof(val) != "string") val = String(val); return (MANY_
或者用零填充: function LeftPadWithZeros(number, length) { var str = '' + number; while (str.length < length) { str = '0' + str; } return str; } 或者使用这个内联“技巧”填充。 原文由 ggg 发布,翻译遵循 CC BY-SA 4.0 许可协议 有用 回复 社区...

clz32(x) Returns the number of leading zeros in a 32-bit binary representation of x Math code Returns the code of the key that triggered the event KeyboardEvent codePointAt() Returns the Unicode value at an index (position) in a string String colorDepth Returns the bit depth of the color...

[Security] Zero-pad all secrets in multiples of 128 bits (instead of 0) by default. [Performance] Massive (100x) speed optimization to padLeft() private function (the second most frequently called block of code internally). [Testing] Added a full jasmine test suite and Karma test runner. ...
