Javascript相当于PHP Explode()

Question

我有一个看起来像这样的字符串:

0000000020C90037:TEMP:数据

我需要在第一次冒号之后抓住所有内容,以便我有TEMP:数据.

我不经常使用Javascript,如果它是PHP我会这样做:

$str = '0000000020C90037:TEMP:data';
$arr = explode(":", $str);
$var = $arr[1].":".$arr[2];

Answer 1

这是从PHP代码直接转换:

//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'

Answer 2

你不需要拆分.你可以使用indexOf和substr:

str = str.substr(str.indexOf(':')+1);

但是,相当于explode将split.

Answer 3

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;
};

应该完全模仿PHP的explode()函数.

'a'.explode('.', 2); // ['a']
'a.b'.explode('.', 2); // ['a', 'b']
'a.b.c'.explode('.', 2); // ['a', 'b.c']

Answer 4

看起来你想分开

Answer 5

试试这个:

arr = str.split (":");

Answer 6

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";

Answer 7

使用 String.split

"0000000020C90037:TEMP:data".split(':')

Answer 8

如果你喜欢 php，请看一下php.JS - JavaScriptexplode

或者在正常的 JavaScript 功能中：`

var vInputString = "0000000020C90037:TEMP:data";
var vArray = vInputString.split(":");
var vRes = vArray[1] + ":" + vArray[2]; `
