更新Javascript

Question

我正在尝试在Javascript中创建更新时钟.当我逐步调试调试器时,一切都正常工作,除了它实际上没有更新跨度.有什么想法吗？

<script type="text/javascript">
// The following line of code is in a setInterval() 
// time is set correctly, according to my debugger
 document.getElementById('clock').value = time;
}
</script>
<span id="clock">This should update
</span>

Answer 1

更改value到innerHTML

document.getElementById('clock').innerHTML = time;

value只是表单元素的有效属性,如input或option.
