Javascript onClick传递php字符串变量

Question

I have this php code snippet and i want to pass string in onclick function. if i just add php variable it will print the string as 3rd argument but sending me error undefined "String Value".

 $mydata_rankings .= "[  \"$captainId\" ,\"$captain_name\", \"$phone\"
 ,\"$email\", \"$points\", \"$rank\", \"<a href='#'
 onclick='updaterank($captainId,$points,$rank)'>Approve</a>\"], ";

The 3rd argument $rank is string first 2 are numbers so no problem.

HTML output:

<a href="#" onclick="updaterank(112,120,Gold)"> Approve </a> 

Answer 1

The problem is that the Gold might not be defined.

You may have wanted it to be string, so enclose $rank between single quotes.

onclick='updaterank($captainId,$points,$rank)'     

change it to:

onclick='updaterank($captainId,$points,\'$rank\')'

here is the complete code:

$mydata_rankings .= "[  \"$captainId\" ,\"$captain_name\", \"$phone\"
 ,\"$email\", \"$points\", \"$rank\", \"<a href='#'
 onclick='updaterank($captainId,$points,\'" . $rank . "\')'>Approve</a>\"], ";
