Answer 1

The cleanest option by using \\DOMDocument :

<?php
$dom = new DOMDocument;
$e = $dom->createElement('a', $u_name);
$a = $dom->appendChild($e);
$a->setAttribute('style',   'color: green;');
$a->setAttribute('href',    'javascript:void(0);');
$a->setAttribute('onclick', 'chatWith("' . $u_code . '","' . $u_name . '");');

echo $dom->saveHTML();

您需要转义那些引号：

echo '<a style="color:green" href="javascript:void(0)" onclick="javascript:chatWith(\''.$u_code.'\',\''.$u_name.'\')" >'.$u_name.'</a>';

Answer 3

You need to append your php variables with "." and escape quotes

 echo '<a style="color:green" href="javascript:void(0)" onclick="javascript:chatWith(\''.$u_code.'\',\''.$u_name.'\')" >'.$u_name.'</a>';

echo '<a style="color:green" href="javascript:void(0)" onclick="javascript:chatWith('.$u_code.','.$u_name.')" >'.$u_name.'</a>';

Answer 8

Sometimes, we should just close PHP, improves readability AND you don't get stuck in nested quotes.

?>

<a style="color: green"
   href="javascript: void(0);"
   onclick="javascript: chatWith('<?php echo $u_code; ?>','<?php echo $u_name; ?>');">
    <?php echo $u_name; ?>
</a>

<?php

Answer 9

You can do this, which is cleaner

$link = '<a onclick="javascript:chatWith({ucode},{uname})" style="color:green" href="javascript:void(0)">{anchor}</a>';

 $link = str_replace(
 $q = "'";
array('{ucode}', '{uname}', '{anchor}'), 
      array($q.$u_code.$q, $q.$u_name.$q, $uname), 
      $link
    );

echo $link;

Answer 10

用这个

echo '<a style="color:green" href="javascript:void(0)" onclick="javascript:chatWith('.$u_code.','.$u_name.')" >'.$u_name.'</a>';

Answer 11

Your formatting seems to be off.

echo '<a style="color:green" href="javascript:void(0)" onclick="javascript:chatWith(\''.$u_code.'\',\''.$u_name.'\')" >'.$u_name.'</a>';

the . is used to append variables to a string in PHP, since you are using single quotes you'll have to escape the string every time you insert a variable.

Hope this helped.
