JavaScript 重定向 URL

Question

下面是我正在使用的与网站表单相关的一些脚本。如果前两个函数无效，我试图让它重定向到特定页面。

发生的情况是，即使函数有效，重定向也会发生

我确信我在这里错过了一些非常简单的东西......

感谢任何帮助!

(function(){
var f1 = fieldname2,
    valid_pickup_postcode = function (postcode) {
    postcode = postcode.replace(/\s/g, "");
    var regex = /^[O,X]{1,2}[0-9]{1,2} ?[0-9][A-Z]{2}$/i;
    return regex.test(postcode);
    };
var f2 = fieldname7,
    valid_dropoff_postcode = function (postcode) {
    postcode = postcode.replace(/\s/g, "");
    var regex = /^[A-Z]{1,2}[0-9]{1,2} ?[0-9][A-Z]{2}$/i;
    return regex.test(postcode);
};

if( AND(f1,f2))
{
   if( valid_pickup_postcode(f1) && valid_dropoff_postcode(f2))
   {
      return 'Please select the vehicle you require for your delivery';
   }
   else
   {
      return window.location.href = "http://www.bing.com";
   }
}
else
{
return '';
}
})()

(function() {
    var f1 = fieldname2,
        valid_pickup_postcode = function(postcode) {
            postcode = postcode.replace(/\s/g, "");
            var regex = /^[O,X]{1,2}[0-9]{1,2} ?[0-9][A-Z]{2}$/i;
            return regex.test(postcode);
        };
    var f2 = fieldname7,
        valid_dropoff_postcode = function(postcode) {
            postcode = postcode.replace(/\s/g, "");
            var regex = /^[A-Z]{1,2}[0-9]{1,2} ?[0-9][A-Z]{2}$/i;
            return regex.test(postcode);
        };

    if (AND(f1, f2)) {
        if (valid_pickup_postcode(f1) && valid_dropoff_postcode(f2)) {
            return 'Please select the vehicle you require for your delivery';
        } else {
            // return window.location.href = "http://www.bing.com";
            window.location.replace("http://www.bing.com");
        }
    } else {
        return '';
    }
})()

window.location.replace("http://www.bing.com"); 应该可以解决问题

更新:我做了一些小更改以使您的代码正常工作。对于像验证接送邮政编码这样简单的事情，JS 不是(或不应该)非常复杂:) 这是一个可以使用的更简单的版本

function myValidator(f1, f2) {
    // Validate pickup postal code
    function pickup_postcode(postcode) {
        if (postcode) {
            if (isNaN(postcode)) {
                postcode = postcode.replace(/\s/g, "");
                var regex = /^[O,X]{1,2}[0-9]{1,2} ?[0-9][A-Z]{2}$/i;
                return regex.test(postcode);
            } else {
                return false;
            }
        } else {
            return false;
        }
    }

    // Validate dropoff postal code
    function dropoff_postcode(postcode) {
        if (postcode) {
            if (isNaN(postcode)) {
                postcode = postcode.replace(/\s/g, "");
                var regex = /^[A-Z]{1,2}[0-9]{1,2} ?[0-9][A-Z]{2}$/i;
                return regex.test(postcode);
            } else {
                return false;
            }
        } else {
            return false;
        }
    }

    if (pickup_postcode(f1) === true && dropoff_postcode(f2) === true) { // If both pickup and dropoff postal codes are ok return a message prompting vehicle selection
        return 'Please select the vehicle you require for your delivery';
    } else { // Invalid pickup or dropoff postal code
        // Redirect to website because either pickup or dropoff postal code is invalid
        window.location.replace("https://www.bing.com");
    }
}

myValidator("X909EF", "X909EE"); // Call it this way
