我有这个字符串:

0000000020 c90037:临时数据

我需要这个字符串:

临时:数据。

用PHP我可以这样做:

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

我如何有效地爆炸一个字符串在JavaScript的方式,它在PHP工作?


当前回答

使用String.split

“0000000020 c90037:临时数据”.split(“:”)

如果你喜欢php,看看php. js - JavaScript爆炸

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]; `

看起来你想分开

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";
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的爆炸()函数。

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

使用String.split

“0000000020 c90037:临时数据”.split(“:”)
