在html文檔上移動javascript

我擁有一切工作，我想要它。我唯一無法弄清的是如何將JavaScript移動到頁面的絕對左上角。該程序獲取系統日期，然後將其與兩個季節變量進行比較。在比較它們之後，它確定應該顯示哪個圖像。在html文檔上移動javascript

<head> 
<title>Date Compare</title>

<body> 

<script type="text/javascript"> 

    var a = new Date(); //beginning of Spring 
    var b = new Date(); //beginning of Summer 
    var c = new Date(); //beginning of Fall 
    var d = new Date(); //beginning of Winter 
    var today = new Date(); 

    //Set actual Dates 
    a.setFullYear(2012, 2, 20); 
    b.setFullYear(2012, 5, 20); 
    c.setFullYear(2012, 8, 22); 
    d.setFullYear(2012, 11, 21); 

    //compare today vs dates of seasons 
    if ((today > a) && (today <= b)) 
    { 
     document.write("<img src = Images/Spring.jpg>"); 
    } 
    else if ((today > b) && (today <= c)) 
    { 
     document.write("<img src = Images/Summer.jpg>"); 
    } 
    else if ((today > c) && (today <= d)) { 
     document.write("<img src = Images/Fall.jpg>"); 
    } 
    else if ((today >= d) || (today <= a)) { 
     document.write("<img src = Images/Winter.jpg width=320 height=480>"); 
    } 

</script> 
</body> 
</html>

首先，這與iPhone的發展無關。

其次，只需使用CSS。

<style type="text/css"> 
.top-left { 
    position:absolute; 
    top:0; 
    left:0; 
} 
</style> 

document.write("<img class='top-left' src = Images/Spring.jpg>");
