JavaScript仅在Chrome中工作

字段验证后，下面的代码不会返回上一页的任何值。但这段代码只在Chrome中有效。Firefox和IE不起作用

function quickenquiryValidator() {
    // Make quick references to our fields
    var regex = /^[a-zA-Z ]{2,30}$/;
    var qename = document.getElementById('qename');
    var qemobile = document.getElementById('qemobile');
    var qeemail = document.getElementById('qeemail');
    var calculation = document.getElementById('BotBootInput_Enquiry').value;
    // Check each input in the order that it appears in the form!
    //if(isAlphabet(qename, "Please enter only letters for your name")){
    if (regex.test(qename.value)) {
        if (isNumeric(qemobile, "Please enter a valid mobile number")) {
            if (emailValidator(qeemail, "Please enter a valid email address")) {
                if (check_calculation(calculation, "Please enter valid calculation result")) {
                    document.getElementById("submit4").setAttribute("type", "submit");
                    document.quickenqform.submit();
                    return true;
                }
            }
        }
    }
    else {
        alert("Please enter only letters for your name");
        qename.focus();
        return false;
    }
    return false;
}

控制台中有错误吗？控制台中没有错误。好吧，if语句中有一些分支，在条件未满足时不会返回任何结果。有没有可能，其中一个分支执行了？你能用fiddle来定位这个问题吗？我试过了，但没有成功。
