看起来你想分开

使用String.split

“0000000020 c90037:临时数据”.split(“:”)

var str = "helloword~this~is~me";
var exploded = str.splice(~);

爆炸变量将返回数组，你可以访问数组中的元素，访问它true explosive [nth]，其中nth是你想要得到的值的下标

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";

没有批评John Hartsock的意图，只是为了防止对于使用给定代码的任何人来说分隔符的数量可能会有所不同，我正式建议使用这个…

var mystr = '0000000020C90037:TEMP:data';
var myarr = mystr.split(":");
var arrlen = myarr.length;
var myvar = myarr[arrlen-2] + ":" + myarr[arrlen-1];
