JavaScript，如何通过单击单元格来获得单元格的内容？
<!DOCTYPE html>
<html>
<body>
<script>
function tdClick(self){
alert(self.innerHTML);
}
</script>
<table>
<tr><td onclick="tdClick(this)">1</td><td onclick="tdClick(this)">2</td></tr>
</table>
</body>
</html>

function GetRowNo() {
var e = e || window.event;
var target = e.target || e.srcElement;
if (target.parentNode.tagName.toLowerCase() == "td") {
rowIndex = target.parentNode.parentNode.rowIndex;
}
}
onkeyup(); 函数可以用吧
onclick="alert(this.value)"
alert（this.html（））
