Javascript html5表单无法正常工作

我在我的网站的每一页上都有一个搜索表单，它可以完美地工作，当提交表单时，它会进入一个名为search.php的页面

我的联系页面上也有相同的表格，我也有一个联系表格。 联系人表单没有提交按钮，因为我使用ajax将post变量发送到contact_process.php页面。联系人表单工作正常，但在此页面上搜索表单不工作。。当我按下搜索表单上的提交按钮时，它只刷新整个联系人页面，而不是进入search.php页面。有人能帮忙吗？谢谢

联系人表单的javascript和ajax：

document.getElementById('submit_message').addEventListener('click', sendMessage, false);

function sendMessage(){
    $('#submit_message').removeClass("point_finger_animation");
    $('#pointing_finger').fadeOut();
    xmlhttp = createXHR();
    xmlhttp.onreadystatechange = callback;
    var not_valid_email = false;
    var your_name = document.getElementById("your_name").value;
    var captcha_code = document.getElementById("captcha_code").value;
    var subject = document.getElementById("subject").value;
    var email = document.getElementById("email").value;
    var mobile_number = document.getElementById("mobile").value;
    if(mobile_number.length < 10 || mobile_number.length > 14){
        var not_valid_mobile = true;
    }
    var atpos=email.indexOf("@");
    var dotpos=email.lastIndexOf(".");
    if (atpos<1 || dotpos<atpos+2 || dotpos+2>=email.length){
        var not_valid_email = true;
    }

    var message = document.getElementById("message").value;
    xmlhttp.open("POST", "contact_process.php" ,true);

    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    if((your_name == "" || your_name == null) || (not_valid_mobile) || (not_valid_email) || (message == "" || message == null)){
        $('#container_wrapper').scrollTop(0);
        document.getElementById("form_results").innerHTML = "<p>Message not sent!</p>";
        if(your_name == "" || your_name == null){
            document.getElementById("form_results").innerHTML = "<p>Oops! You forgot to fill in a required field!</p>";
        }else if(not_valid_email){
            document.getElementById("form_results").innerHTML = "<p>The email address you entered is invalid!</p>";
        }else if(not_valid_mobile){
            document.getElementById("form_results").innerHTML = "<p>The mobile number you entered is invalid!</p>";

        }else if(message == "" || message == null){
            document.getElementById("form_results").innerHTML = "<p>Oops! You forgot to fill in a required field!</p>";
        }

    }else{
        xmlhttp.send("your_name=" + your_name + "&email=" + email + "&mobile=" + mobile_number + "&subject=" + subject + "&message=" + message + "&captcha_code=" + captcha_code);

    }
}

function callback(){
    if(xmlhttp.readyState == 4 && xmlhttp.status == 200){
        refreshCaptcha();
        document.getElementById("form_results").innerHTML = xmlhttp.responseText;
        $('#container_wrapper').scrollTop(0);
    }
}

@Malk感谢您在contact表单的结束div中发现缺少的括号：这确实是问题所在：

只是猜测，但可以尝试在contact表单中指定显式动作属性

<form id ="contact_form" method="post" action="some_page_here">

听起来像是HTML错误。这是直接复印/粘贴的吗？注意排队前的那句话。。我从来没有注意到这一点，这确实是问题所在。。我想是因为我的联系方式一直有效，所以我没想到要检查一下。。你帮我省了几个小时试图解决这个问题。谢谢。谢谢，但是因为我使用ajax发送联系人表单，所以我不需要动作属性。结果是我在联系人表格中的div上缺少了一个结束括号。。感谢您的帮助：
