前端不能像java一样有内置的uuid生成包,所以需要自己写一个function,每次调用这个函数都会生成一个不同的字符串,代码如下: getuuid() { var uid = []; var hexDigits = "0123456789abcdefghijklmnopqrst"; // 这里可以随意写长度越大,生成的随机字符串越不容易重复 for (var i = 0; i ; i++) { uid[i] = hexDigits.substr(Math.floor(Math.ra…
方法一. function uuid() { var s = []; var hexDigits = "0123456789abcdef"; for (var i = 0; i < 36; i++) { s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1); } s[14] = "4"; // bits 12-15 of the time_hi_and_version field to 001…
function uuid() { var s = []; var hexDigits = "0123456789abcdef"; for (var i = 0; i < 32; i++) { s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1); } s[14] = "4"; // bits 12-15 of the time_hi_and_version field to 0010 s[1…
function uuid(len, radix) { var chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.split(''); var uuid = [], i; radix = radix || chars.length; if (len) { // Compact form for (i = 0; i < len; i++) uuid[i] = chars[0 | Math.random(…
js生成随即字符串 /* *js生成随即字符串原来如此简单 *toString() radix argument must be between 2 and 36 */ function uuid() { return Math.random().toString(36).substring(3, 8) } //7rh32…
