href似乎不起作用

Question

为什么以下不起作用。它只需要我到index.php页面并切断“获取”数据

 <div class="wrapper">
        <form class="form-signin" method="post">       
            <h2 class="form-signin-heading">Customer Not Found</h2>
              No customer was found matching <?=$_POST['phone'];?>.<br/>
              You can create a new customer with this number, or search again<br/>
              <button
                      class="btn btn-lg btn-primary btn-block"

                      id="createCust"
              >
                     Create A New Customer
              </button>   
              <button class="btn btn-lg btn-primary btn-block" type="submit" name="login">Search Again</button>   
        </form>
    </div>
 <script type="text/javascript">
    document.getElementById("createCust").onclick = function () {
        location.href = "index.php?proc=newCust&p=<?=$_SESSION['phone'];?>";
    };
</script>

Answer 1

正如@Teemu所说：

  

表单中按钮的默认操作是提交表单。一个   挂起的服务器调用将阻止对location.href的更改。定义   按钮作为按钮的类型。 -

我将“type”作为提交，将其更改为type =“button”解决了这个问题。
