Answer 1

在onClick事件初始化中转义双引号" ，而不是将new Date()打印为纯文本，就像使用变量对它进行连接一样：

echo "['" . $row['ac'] . " ','<span onclick=\"alert('test')\">Click here!</span>', " . new Date( $row['start']) . ", " . new Date($row['end']) . "], ";

Answer 2

您需要转义alert span中使用的双引号"

echo "['". $row['ac']. " ','<span onclick=\"alert(\'test\')\">Click here!</span>',  new Date( ". $row['start']. " ),  new Date( ". $row['end']. " )], ";

Answer 3

You're not escaping properly around onClick

Try this

echo "['". $row['ac']. " ','<span onclick=\"alert(\'test\')\">Click here!</span>',  new Date( ". $row['start']. " ),  new Date( ". $row['end']. " )], ";
