<input type=text onClick="this.value=(new Date).toLocaleString()">

Answer 6

补充一下：
<input type=text value=日期时间 onClick="this.value=(new Date).toLocaleString()">
<input type=text value=仅日期 onClick="this.value=(new Date).toLocaleString().replace(/ .+/,'')">
<input type=text value=仅时间 onClick="this.value=(new Date).toLocaleString().replace(/.+ /,'')">
