my question is how I can echo this the right way because the variable in the onclick function gives out a undefined error
我的问题是如何以正确的方式回应这个,因为onclick函数中的变量给出了一个未定义的错误
$openchat="<a href='javascript:void(0)' onClick='return chatWith(" . $livenaam .")'>" . $livenaam . "</a><br>";
echo $openchat;
I want to use it in a loop to get a list off users online for the chat
我想在循环中使用它来获取用户在线聊天列表
Thanks, Richard

Looks like you are missing some quotes:
看起来你错过了一些引用:
$openchat="<a href='javascript:void(0)' onClick='return chatWith(\"" . $livenaam ."\")'>" . $livenaam . "</a><br>";
or for increased security:
或者为了提高安全性:
$openchat="<a href='javascript:void(0)' onClick='return chatWith(\"" . htmlspecialchars($livenaam,ENT_QUOTES) ."\")'>" . htmlspecialchars($livenaam,ENT_QUOTES) . "</a><br>";

Try this:
'<a href="javascript:void(0)" onclick="return chatWith(' . htmlspecialchars(json_encode($livenaam)) . ')">' . htmlspecialchars($livenaam) . '</a><br>'
If json_encode
is not available, try this:
如果json_encode不可用,请尝试以下方法:
'<a href="javascript:void(0)" onclick="return chatWith(' . htmlspecialchars('"'.addslashes($livenaam).'"') . ')">' . htmlspecialchars($livenaam) . '</a><br>'
