Javascript string to Guid
提问by Linc Abela
in javascript, what is the easiest way to convert this string
在javascript中，转换此字符串的最简单方法是什么
798205486e954fa880a0b366e6725f71
to GUID format like this
像这样的 GUID 格式
79820548-6e95-4fa8-80a0-b366e6725f71
this is the messy way I do it :) im looking for the cleanest way
这是我这样做的凌乱方式:) 我正在寻找最干净的方式
var employeeId = shift.employee.id.substring(0, 8) + "-" + shift.employee.id.substring(8, 12)
+ "-" + shift.employee.id.substring(12, 16) + "-" + shift.employee.id.substring(16, 20) + "-" + shift.employee.id.substring(20, 32);

I did it in string manipulation
我是在字符串操作中做到的
var str = "798205486e954fa880a0b366e6725f71";
var parts = [];
parts.push(str.slice(0,8));
parts.push(str.slice(8,12));
parts.push(str.slice(12,16));
parts.push(str.slice(16,20));
parts.push(str.slice(20,32));
var GUID = parts.join('-');
console.log(GUID) // prints expected GUID
I did it this way because I don't like inserting characters between strings. If there is any problem tell me.
我这样做是因为我不喜欢在字符串之间插入字符。如果有任何问题告诉我。
Or you could use a forloop like bellow
或者你可以使用for像波纹管这样的循环
var str = "798205486e954fa880a0b366e6725f71";
var lengths = [8,4,4,4,12];
var parts = [];
var range = 0;
for (var i = 0; i < lengths.length; i++) {
parts.push(str.slice(range,range+lengths[i]));
range += lengths[i];
};
var GUID = parts.join('-');
console.log(GUID);

Cleanest way?
最干净的方式？
Shortest:
最短：
var txt = shift.employee.id;
txt.replace(/([0-z]{8})([0-z]{4})([0-z]{4})([0-z]{4})([0-z]{12})/,"----");
//"79820548-6e95-4fa8-80a0-b366e6725f71"
or if you don't care about the acceptable characters, it can be be even shorter (and cleaner):
或者如果你不关心可接受的字符，它可以更短（更干净）：
txt.replace(/(.{8})(.{4})(.{4})(.{4})(.{12})/,"----"); //boom!
Some don't like using regex for everything, but I liked it.
有些人不喜欢对所有事情都使用正则表达式，但我喜欢它。

Try this function, It will return string in GUID format
试试这个函数，它会以 GUID 格式返回字符串
function getGuid(str){
return str.slice(0,8)+"-"+str.slice(8,12)+"-"+str.slice(12,16)+
"-"+str.slice(16,20)+"-"+str.slice(20,str.length+1)
}

Or you would try-
或者你会尝试-
var guid = (function () {
function s4() {
return Math.floor((1 + Math.random()) * 0x10000)
.toString(16)
.substring(1);
}
return function () {
return s4() + s4() + '-' + s4() + '-' + s4() + '-' +
s4() + '-' + s4() + s4() + s4();
};
})();
WhereYour new guid be like-
你的新向导在哪里——
var newGuid= guid();
newGuid returns- 7d4b3ef0-b5bb-5c42-2a02-80a4371babf8
newGuid 返回- 7d4b3ef0-b5bb-5c42-2a02-80a4371babf8
