Javascript Equivalent to PHP Explode()
提问by Doug Molineux
I have this string:
我有这个字符串：
0000000020C90037:TEMP:data
0000000020C90037：TEMP：数据
I need this string:
我需要这个字符串：
TEMP:data.
温度：数据。
With PHP I would do this:
使用 PHP 我会这样做：
$str = '0000000020C90037:TEMP:data';
$arr = explode(':', $str);
$var = $arr[1].':'.$arr[2];
How do I effectively explodea string in JavaScript the way it works in PHP?
我如何有效地explode在 JavaScript 中使用字符串作为它在 PHP 中的工作方式？

This is a direct conversion from your PHP code:
这是从您的 PHP 代码的直接转换：
//Loading the variable
var mystr = '0000000020C90037:TEMP:data';
//Splitting it with : as the separator
var myarr = mystr.split(":");
//Then read the values from the array where 0 is the first
//Since we skipped the first element in the array, we start at 1
var myvar = myarr[1] + ":" + myarr[2];
// Show the resulting value
console.log(myvar);
// 'TEMP:data'

String.prototype.explode = function (separator, limit)
{
const array = this.split(separator);
if (limit !== undefined && array.length >= limit)
{
array.push(array.splice(limit - 1).join(separator));
}
return array;
};
Should mimic PHP's explode() function exactly.
应该完全模仿 PHP 的 expand() 函数。
'a'.explode('.', 2); // ['a']
'a.b'.explode('.', 2); // ['a', 'b']
'a.b.c'.explode('.', 2); // ['a', 'b.c']

Try this:
尝试这个：
arr = str.split (":");

create's an object :
创建一个对象：
// create a data object to store the information below.
var data = new Object();
// this could be a suffix of a url string.
var string = "?id=5&first=John&last=Doe";
// this will now loop through the string and pull out key value pairs seperated
// by the & character as a combined string, in addition it passes up the ? mark
var pairs = string.substring(string.indexOf('?')+1).split('&');
for(var key in pairs)
{
var value = pairs[key].split("=");
data[value[0]] = value[1];
}
// creates this object
var data = {"id":"5", "first":"John", "last":"Doe"};
// you can then access the data like this
data.id = "5";
data.first = "John";
data.last = "Doe";

console.log(('0000000020C90037:TEMP:data').split(":").slice(1).join(':'))
console.log(('0000000020C90037:TEMP:data').split(":").slice(1).join(':'))
outputs: TEMP:data
输出： TEMP:data
- .split() will disassemble a string into parts
- .join() reassembles the array back to a string
- when you want the array without it's first item, use .slice(1)
- .split() 将字符串分解成部分
- .join() 将数组重新组合成字符串
- 当您想要没有第一项的数组时，请使用 .slice(1)

If you like php, take a look at php.JS - JavaScript explode
喜欢php的可以看看php.JS——JavaScript爆炸
Or in normal JavaScript functionality: `
或者在普通的 JavaScript 功能中：`
var vInputString = "0000000020C90037:TEMP:data";
var vArray = vInputString.split(":");
var vRes = vArray[1] + ":" + vArray[2]; `

Use String.split
使用 String.split
"0000000020C90037:TEMP:data".split(':')
"0000000020C90037:TEMP:data".split(':')

With no intentions to critique John Hartsock, just in case the number of delimiters may vary for anyone using the given code, I would formally suggest to use this instead...
无意批评John Hartsock，以防万一使用给定代码的任何人的分隔符数量可能会有所不同，我会正式建议改用它......
var mystr = '0000000020C90037:TEMP:data';
var myarr = mystr.split(":");
var arrlen = myarr.length;
var myvar = myarr[arrlen-2] + ":" + myarr[arrlen-1];
