javascript - JS 函数返回 false 变量，而本应为 true

Question

我对返回变量的状态有疑问。我有“altFormValidate”功能。本质上问题是，当我调用它时，如果蜜 jar 计数为 0，验证运行正常，并且“validationResult”变量返回 true，但如果蜜 jar 计数大于 0，“validationResult”变量仍然返回 false，即使在执行了应该使其成立的代码之后。

function altFormValidate(intendedFormID){ //Validate honeypot traps
    var validationResult = false;
    }

    var honeyPotFields = ["Fname", "EmailAddress", "Lname", "Telephone", "Address1", "Address2", "Surname", "Title"];
    var honeyPotCount = 0;
    honeyPotFields.forEach(function(entry) { //Check page for honeypots filled out
        if($('#' + entry).length >= 1){
            var honeyPotVal = $('#' + entry).val();
            if (honeyPotVal !== ""){
                honeyPotCount = honeyPotCount + 1; //Count successful honeypot traps
            }
        }
    });
    if (!honeyPotCount > 0) //Check honeypot count
    {
        $('#' + intendedFormID).attr("action", formAction); //Append SF action to form
        validationResult = true;
    }
    else 
    {
        if (honeyPotCount == 1){ //If one honeypot filled in
            //SUSPECT - implement further checks
                $.colorbox({ //init popup with confirmation input: "#machine-check"
                href: "/inc/form-confirmation.html",
                transition: "elastic",
                speed: 350,
                opacity: 0.65,
                className: "seg-window",
                onComplete: function() {
                    jQuery('#colorbox').find('a.btn-close, a.close, a.cancel').unbind('click.closeColorbox').bind('click.closeColorbox', function(e) {
                        jQuery.colorbox.close();
                        e.preventDefault();
                    });
                    jQuery('#machine-check').bind('change', function(e) {
                            jQuery.colorbox.close();
                            e.preventDefault();
                            validationResult = true; //This code doesn't seem to change the variable "validationResult" when I call the entire function altFormValidate but I know that changing "machine-check" does change the variable. 
                        });
                    }
             });
        }
        else if (honeyPotCount == 2){ //If two honeypots filled in
            //PRIME SUSPECT - init Captcha/Akismet etc
            alert("Robot Alert!");
            validationResult = false;
        }

    } return validationResult;
}

我在提交表单时像这样调用上面的函数:

   var req = true; 
   if(req){ //If required fields are filled in
                var extraValidation = altFormValidate('WebToLeadForm', 'webToLeadPost');

                 if (extraValidation == true){
                    alert("form sent");
                    //document.WebToLeadForm.submit();
                    return true;
                }
            }

所以我的问题是，为什么如果没有找到蜜 jar ，extraValidation() 返回 true，但如果找到蜜 jar ，则返回 false，但随后执行相关代码使其变为 true？我认为问题在于我返回 validResult 变量的位置。

Answer 1

我没有测试过，但我猜

if (!honeyPotCount > 0)

不等于

if (!(honeyPotCount > 0))
