前端數據怎麼生成?function getUUID() { return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) { var r = Math.random()*16|0, v = c == 'x' ? r : (r&0x3|0x8); return v.toString(16); }); } console.log(getUUID());，下面我們就來說一說關于前端數據怎麼生成?我們一起去了解并探讨一下這個問題吧!

前端數據怎麼生成

function getUUID() { return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) { var r = Math.random()*16|0, v = c == 'x' ? r : (r&0x3|0x8); return v.toString(16); }); } console.log(getUUID());

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 0010 s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1); // bits 6-7 of the clock_seq_hi_and_reserved to 01 s[8] = s[13] = s[18] = s[23] = "-"; var uuid = s.join(""); return uuid; } console.log(uuid());

function guid2() { function S4() { return (((1 Math.random()) * 0x10000) | 0).toString(16).substring(1); } return (S4() S4() "-" S4() "-" S4() "-" S4() "-" S4() S4() S4()); }
