JavaScript或jQuery相当于PHP的strstr()函数

Question

在jQuery或JavaScript中是否有与strstr()PHP 相同的功能？

我有一个AJAX响应应该是1,2,3,12,13,23或123.我想检查1是否存在,然后如果2存在则则存在3.

试试这个:

function strstr(haystack, needle, bool) {
    // Finds first occurrence of a string within another
    //
    // version: 1103.1210
    // discuss at: http://phpjs.org/functions/strstr    // +   original by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)
    // +   bugfixed by: Onno Marsman
    // +   improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)
    // *     example 1: strstr(‘Kevin van Zonneveld’, ‘van’);
    // *     returns 1: ‘van Zonneveld’    // *     example 2: strstr(‘Kevin van Zonneveld’, ‘van’, true);
    // *     returns 2: ‘Kevin ‘
    // *     example 3: strstr(‘name@example.com’, ‘@’);
    // *     returns 3: ‘@example.com’
    // *     example 4: strstr(‘name@example.com’, ‘@’, true);    // *     returns 4: ‘name’
    var pos = 0;

    haystack += "";
    pos = haystack.indexOf(needle); if (pos == -1) {
        return false;
    } else {
        if (bool) {
            return haystack.substr(0, pos);
        } else {
            return haystack.slice(pos);
        }
    }
}
