How can I pass """ to a Javascript function-call made inside an HTML-tag?

I have a Javascript function (named insert_formatText) which inserts text into a specified textarea. This function takes 4 parameters: - opentag (the open tag) - closetag (the close tag) - formid (id-attribute value of the form) - elementid (id-attribute value of the textarea)

My function works very well except for when you set opentag as """ and closetag as """. In that case, it simply breaks.

<a href="javascript:;" onclick="insert_formatText('"""', '"""', 'foo', 'bar');">INSERT TRIPLE-QUOTES</a>

Extra Detail

I actually use PHP to loop through an array containing the opentag and closetag values as a key => value pair. In the loop, I pass those values to a function:

function editorButton($pre, $suf, $fid, $eid, $label){
    $str = <<<EOT
            <a href="javascript:;" onclick="insert_formatText('$pre', '$suf', '$fid', '$eid');">$label</a>
EOT;
    return $str;
}

So my question: is there 开发者_Python百科anyway to get this to work for double-quotes without much changing? Or will I have to find a different method to generate these buttons?

You can escape the quotes using a backslash in this manner:

<a href="javascript:;" onclick="insert_formatText('\"\"\"', '\"\"\"', 'foo', 'bar');">INSERT TRIPLE-QUOTES</a>

you have to add slashes:

function editorButton($pre, $suf, $fid, $eid, $label){
    $pre = addslashes($pre);
    $suf = addslashes($suf);
    $str = <<<EOT
            <a href="javascript:;" onclick="insert_formatText('$pre', '$suf', '$fid', '$eid');">$label</a>
EOT;
    return $str;
}

then it will yield you:

<a href="javascript:;" onclick="insert_formatText('\"\"\"', '\"\"\"', 'foo', 'bar');">INSERT TRIPLE-QUOTES</a>

Well, you are inside a tag and you've opened a string as ". So you need escapes

<a href="javascript:;" 
   onclick="insert_formatText('\"\"\"', '\"\"\"', 'foo', 'bar');"
>INSERT TRIPLE- QUOTES</a>

Or the other way around, you can try this

<a href="" onclick='insert_formatText("\"\"\"", "\"\"\"" "foo", "bar");'>INSERT TRIPLE- QUOTES</a>

You should encode your quotes as entities in the html. i.e.

<a href="javascript:;" onclick="insert_formatText('&quot;&quot;&quot;', '&quot;&quot;&quot;', 'foo', 'bar');">INSERT TRIPLE-QUOTES</a>

You can use the PHP function htmlentities for this.
