javascript再html代码里自动促发js的一个逻辑错误

错误：

<script type="text/javascript">

function myDate(){

var nowDate = new Date();

document.getElementById("dateTime1").innerHTML = nowDate.toLocaleTimeString();

setTimeout("myDate();",1000);

}

</script>

<script type="text/javascript">//错在这里 这个script应该放在p标签的后面 术语逻辑错误

myDate();

</script>

<p id="dateTime1" style="float:right;border:1px solid #000;">t</p>

正确：

<script type="text/javascript">

function myDate(){

var nowDate = new Date();

document.getElementById("dateTime1").innerHTML = nowDate.toLocaleTimeString();

setTimeout("myDate();",1000);

}

</script>

<p id="dateTime1" style="float:right;border:1px solid #000;">t</p>

<script type="text/javascript">

myDate();

</script>
