问如何获取两个字符之间的文本？

EN

var test_str = "|text to get| Other text.... migh have \"|\"'s ...";
var start_pos = test_str.indexOf('|') + 1;
var end_pos = test_str.indexOf('|',start_pos);
var text_to_get = test_str.substring(start_pos,end_pos)
alert(text_to_get);

function getSubStr(str, delim) {
    var a = str.indexOf(delim);

    if (a == -1)
       return '';

    var b = str.indexOf(delim, a+1);

    if (b == -1)
       return '';

    return str.substr(a+1, b-a-1);
    //                 ^    ^- length = gap between delimiters
    //                 |- start = just after the first delimiter
}

print(getSubStr('|text to get| Other text.... migh have "|"s ...', '|'));

// Output: text to get

string = '|text to get| Other text.... migh have "|"\'s ...';
string = string.replace(/^\|[^|]*\|/, '');
