JavaScript弹出框位置

Question

I am trying to implement a javascript pop-up box, but I am not sure how to fix the position of the pop-up window. 我正在尝试实现一个javascript弹出框，但是我不确定如何确定弹出窗口的位置。 Please check the below fiddle. 请检查以下小提琴。 When I click on the button, the box somehow appears in the middle of the page. 当我单击按钮时，该框会以某种方式出现在页面中间。 Is there a way to make it appears right under my button? 有没有办法让它显示在我的按钮下方？

<html lang="en" dir="ltr">
<head>
<style type="text/css">
.popup{
    position:relative;
    top:0px;
    left:0px;
    margin:0px auto;
    width:200px;
    height:150px;
    font-family:verdana;
    font-size:13px;
    padding:10px;
    background-color:rgb(240,240,240);
    border:2px solid grey;
    z-index:100000000000000000;
    display:none
    }

.cancel{
    display:relative;
    cursor:pointer;
    margin:0;
    float:right;
    height:10px;
    width:14px;
    padding:0 0 5px 0;
    background-color:red;
    text-align:center;
    font-weight:bold;
    font-size:11px;
    color:white;
    border-radius:3px;
    z-index:100000000000000000;
    }

.cancel:hover{
    background:rgb(255,50,50);
    }

</style>
</head>
<body>
<button onClick="openPopup();">click here</button>
<div id="test" class="popup">
    This is a test message
    <div class="cancel" onclick="closePopup();"></div>
</div>
</body>
</html>

and 和

function openPopup() {
    document.getElementById('test').style.display = 'block';
}

function closePopup() {
    document.getElementById('test').style.display = 'none';
}

(forked from javascript onclick create(element) div viz popup box ) （由javascript onclick create（element）div viz弹出框派生）

Thanks! 谢谢！

Answer 1

In your CSS popup make position: absolute; 在CSS popup position: absolute; and remove top and left property so your popup would become 并remove top and left属性，使您的popup变为

.popup{
    position:absolute;
    margin:0px auto;
    width:200px;
    height:150px;
    font-family:verdana;
    font-size:13px;
    padding:10px;
    background-color:rgb(240,240,240);
    border:2px solid grey;
    z-index:100000000000000000;
    display:none
    }

Rest all is fine 休息都很好

Answer 2

Remove margin: 0 auto property. 删除margin: 0 auto属性。 Because It is enforcing the element to be in center. 因为它强制元素居中。
