javascript的src中如何用变量控制

比如说
<script type="text/javascript" src="http://192.168.1.118/map/map2.aspx?w=600&h=500">
</script>

这之中的w=600&h=500我想用变量来控制,怎么做?

Answer 1

两种办法：
var w = 600, h = 500;

1. document.write('<script type="text/javascript" src="http://192.168.1.118/map/map2.aspx?w=' + w + '&h=' + 500 + '">
</sc' + 'ript>'

2. <script type="text/javascript" src="" id="js1"></script>
<script>
document.getElementById('js1').src = 'http://192.168.1.118/map/map2.aspx?w=' + w + '&h=' + 500
</script>

Answer 2

写另个JS吧
<script type="text/javascript">
var _header = 'script';
var _w = 600;
var _h = 500;
var _url = 'http://192.168.1.118/map/map2.aspx';

document.write("<"+_header+" type=\"text/javascript\" src=\""+_url+"?w="+_w+"&h="+_h+"\"></"+_header+">");

</script>

Answer 3

var img = document.getElementById('box'); 获取到这个id为box 的图片

img.src = "/images/1.jpg"; 改变他的src值

Answer 4

JSP吗？
var wh="w=600&h=500";

src="http://192.168.1.118/map/map2.aspx?"+ wh;

Answer 5

用seajs管理你的JS就行了吧？
