Hi,

Please visit following link :

下一行：

The next line:

msg += "<p style="font-family:verdana; font-size:13px; color:#161616;">Artha Travels</p>";

会产生错误，因此您应该在中使用 \更改 如下例所示：

generates the error, so you should change it by using \" in plase of " like in the next example:

msg += "<p style=\"font-family:verdana; font-size:13px; color:#161616;\">Artha Travels</p>";
