窗口.第二次定位不工作

我在一个带有验证码的表单中使用以下代码。如果验证码正确，则为$success = 1，否则为$success=2。若captcha未填写，则为$success=1。

id=validation与captcha一起出现在页面的最底部，id=success与div元素一起出现在页面的最顶部。

问题:

第一次测试:
1) captcha是正确的->点击提交->页面出现在顶部

第二次测试:
1) captcha不正确或未填写->点击提交->页面来到底部
2)验证码是正确的->按回车->页面留在底部(而它应该放到顶部)

Java Script:

var myVariable = <?php echo(json_encode($success)); ?>;
if (myVariable == 2) {
    window.location = (""+window.location).replace(/#[A-Za-z0-9_]*$/,'')+"#validation"
};
if (myVariable == 3) {
    window.location = (""+window.location).replace(/#[A-Za-z0-9_]*$/,'')+"#validation"
};
if (myVariable == 1) {
    window.location = (""+window.location).replace(/#[A-Za-z0-9_]*$/,'')+"#success"
};

<script type='text/javascript'>
var myVariable = <?php echo(json_encode($success)); ?>;
if (myVariable == 2 || myVariable == 3) {
window.location.href = (""+window.location.href).replace(/#[A-Za-z0-9_]*$/,'')+"#validation"
};
if (myVariable == 1) {
window.location.href = (""+window.location.href).replace(/#[A-Za-z0-9_]*$/,'')+"#success"
};
</script>
