我是 javascript 和 css 的初学者

现在我想创建一个弹出框显示消息，同时html正文是半透明的。但是现在我做的不是那么好，我该怎么办？

我需要你的帮助

我的代码在下面

html代码

<div id="confirm_box" class="info_box">
<div class="info_box confirm_info">
    <div class="info_box confirm_title">{$confirmTitle}</div>
    <div class="info_box confirm_close">
        <span id="confirm_close" class="info_box confirm_close">×</span>
    </div>
</div>

<div id="info_box_content" class="info_box confirm_content">
    <div class="info_box info_img_box">
        <img src="{$url_app_dir}img/confirm_dog.png" class="info_box confirm_img"/>
    </div>
    <div id="content_box" class="info_box content_box">
    {$confirmContent}<label id="info_box_text" class="info_box info_text"></label>
    </div>
</div>
<div class="info_box confirm_button">
    <button class="info_box confirm_submit" >确认</button>
</div>

js代码

window.onload = function ()
{
var confrimWin = document.getElementById("confirm_box");
var comfirmBtn = document.getElementById("show_confirm_box");
var closeBtn = document.getElementById("confirm_close");
var bodyElement = document.getElementsByTagName("body")[0];
//show pop-up box
comfirmBtn.onclick = function()
{           
    confrimWin.style.display = "block";     
    bodyElement.setAttribute('class',"body_mask");

    var text = document.getElementById("name").value;       
    document.getElementById("info_box_text").innerHTML= text ;
};
//close box
closeBtn.onclick = function()
{
    confrimWin.style.display = "none";
    bodyElement.setAttribute('class',"");   
}   

//get mouse Object
document.onclick = function(){  
    var e = arguments[0] || window.event;  
    var eventSource = e.srcElement||e.target;
    var isShow = eventSource.className.toLowerCase().indexOf('info_box');

    if(eventSource.className == 'btn'){
        comfirmBtn.onclick();
    }
    else if( isShow < 0)
    {

        confrimWin.style.display = "none";
        bodyElement.setAttribute('class',"");   
    }
}

};

作为 javascript&css 的初学者，我尝试一次又一次地解决问题。最后以一种不太喜欢的方式解决了它

下面是我改过的代码，比以前好多了

#confirm_box{
position:fixed;
top:50%;
left:50%;
width:500px;
height:300px;
border-radius: 5px 5px 5px 5px;
background:#fff;
border:4px solid rgb(   220,220,220);
margin:-102px 0 0 -202px;
z-index: 1002;/*this add css code will show confirm_box upon body_mask*/
display:none;
}

html代码

<div id="confirm_box" class="info_box">
</div>
<div id="hide_info_box" class="body_mask"></div>

javascript代码

window.onload = function ()
{
var confrimWin = document.getElementById("confirm_box");
var comfirmBtn = document.getElementById("show_confirm_box");
var closeBtn = document.getElementById("confirm_close");
var hideElement = document.getElementById("hide_info_box");

//show info box 
comfirmBtn.onclick = function()
{           
    confrimWin.style.display = "block";
    hideElement.style.display = "block";
    var text = document.getElementById("name").value;       
    document.getElementById("info_box_text").innerHTML= text ;
};

    //close info box
closeBtn.onclick=hideElement.onclick=function()
{
    confrimWin.style.display = "none";
    hideElement.style.display = "none"; 
}
};
