setinterval表示未定义函数，但它是 [英] setinterval says not defined function but it is

问题描述

我具有在HEAD内部定义的此功能:

i have this function which i define inside HEAD:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.min.js">
function live() {
    $.get("http://mydomain.com/script.php", function(data){
        var timer = data;
        var elm = document.getElementById("live");
        if (timer == 1){
         elm.style.display = 'block';
        } else{
         elm.style.display = 'none';
        }     
    });
}
</script>

然后我在文档的最后做一个这样的循环:

and then i do a loop like this at the very end of my document:

<script type="text/javascript">
 setInterval(live,10000);
</script>

但是我收到一条错误消息，说未定义live.这是为什么?你能告诉我我做错了什么吗?

but i get an error saying live is not defined. Why is that? Could you please tell me what im doing wrong?

谢谢.

推荐答案

将代码放在单独的<script>标记中.一旦<script>标记具有src属性，将忽略该标记的任何内容，而使用给定资源.所以只要这样做:

Put your code in an separate <script> tag. As soon as a <script> tag has a src attribute, any content of that tag is ignored in favor of the given resource. so just do this:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script>
function live() {
    $.get("http://mydomain.com/script.php", function(data){
        var timer = data;
        var elm = document.getElementById("live");
        if (timer == 1){
         elm.style.display = 'block';
        } else{
         elm.style.display = 'none';
        }     
    });
}
</script>
