The JavaScript code you are sending (as seen by using print $response) is:

$('override_...').innerHTML="<a href='#' onClick='javascript:makeForm( +"...", "...", "...");'>...</a>';

but it should be

$('override_...').innerHTML="<a href='#' onClick='javascript:makeForm( +\"...\", \"...\", \"...\");'>...</a>";

The first double-quote is wrongly closed with a single quote, and you have unescaped double-quotes.

Other potential problems:

  • Is $('override_123') valid JavaScript? I've never seen that syntax before, but I have little JavaScript experience.
  • Are $componentId, $componentType and $newTitle properly escaped to be used in a JavaScript double-quoted string? (\ => \\, " => \")
  • Are $componentId, $componentType and $newTitle properly escaped to be used in an HTML single-quoted value? (& => &amp;, ' => &#39;)
  • Is $newTitle properly escaped to be used in HTML? (& => &amp;, < => &lt;)

Update: The following addresses quoting issues:

use strict; use warnings; use HTML::Entities qw( encode_entities ); sub js_from_text { for (@_ ? $_[0] : $_) { s/([\\"])/\\$1/g; return qq{"$_"}; } } sub html_from_text { for (@_ ? $_[0] : $_) { return encode_entities($_); } } my ($text_componentId, $text_componentType, $text_newTitle) = ...; my $js_component = js_from_text("override_$text_componentId"); my $js_componentId = js_from_text($text_componentId); my $js_componentType = js_from_text($text_componentType); my $js_newTitle = js_from_text($text_newTitle); my $js_onClick = "makeForm($js_componentId, $js_componentType, $ +js_newTitle);"; my $html_onClick = html_from_text($js_onClick); my $html_newTitle = html_from_text($text_newTitle); my $html = qq{<a href="#" onClick="javascript:$html_onClic +k">$html_newTitle</a>}; my $js_html = js_from_text($html); my $js_response = "\$($js_component).innerHTML = $js_html;"; print("$js_response\n");

There is a situation where hungarian notation is very useful. Making Wrong Code Look Wrong is a worthwhile read.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
