如何在PHP中使用JQuery向表中添加输入标记？

Today I stumbled across this problem when I try to dynamically add an input tag to a row in a table.

"SyntaxErrpr: missing ) after argument list"

The code I used:

//creates a input element based on the fieldname, fieldvalue and fieltype.

public function createInput($aFieldName, $aFieldValue, $aInputType)
{   
    echo '<script>';
    echo '$("#TableContainer tr:last").';
    echo    'append($("<tr><td>"'.$aFieldName.'"</td><td><input type="'.$aInputType.'" name= "'.$aFieldName.'"></td></tr>"));';
    echo '</script>';
}

input:

fieldname = classnumber,
fieldvalue = classnumber,
inputetype = text,

Output

When I use it without using the variables it somehow works and doesn't give me the error mentioned above.

//creates a input element based on the fieldname, fieldvalue and fieltype.
public function createInput($aFieldName, $aFieldValue, $aInputType)
{   
    echo '<script>';
    echo '$("#TableContainer tr:last").';
    echo    'append($("<tr><td>test</td><td><input type=\"test\" name=\"test\"></td></tr>"));';
    echo '</script>';
}
