in reply to Obtruding Writeup Formatting Tips

This hack "inject" a link directly unter the textarea which, when clicked, will popup a dialog with a graphical Html-Editor.

There's currently a bug in the support for code tags, it will destroy every br tag within code tags.

To use this, put the below code in your free nodelet.

<link rel="stylesheet" type="text/css" href="http://hollihazhomepage.n
+et/ext/resources/css/ext-all-mod.css">
<script type="text/javascript" src="http://hollihazhomepage.net/ext/ad

    As of December 26, 2010, the files referenced in the code above seem no longer available, even through the Wayback Machine.

    I note, however, that versions 2.3.0 and 3.3.1 of Ext JS are available through Sencha in an Open Source Version. Prototype is, of course, still located here.

    That only leaves perlmonks.htmleditor.0.01.js and perlmonks.htmleditor.dialog.0.01.js, which I include below (from my personal archive) for future reference:


    perlmonks.htmleditor.0.01.js :

    // initialize quicktips
Ext.QuickTips.init();

Ext.namespace('Perlmonks');

Perlmonks.HtmlEditor = Ext.extend( Ext.form.HtmlEditor, { 
    enableAlignments: false,
    enableLinks: false,
    enablePMLinks: false,
    createToolbar : function(editor){
        Perlmonks.HtmlEditor.superclass.createToolbar.call(this, edito
+r);
        this.tb.items.item('backcolor').hide();
    },
    
    setValue : function(v){
    
        
        v = v.replace(/\n/g, String.fromCharCode(222));
        
        while ( v.match(/<code>(.+?)<\/code>/i) ) 
        { 
            v = v.replace(/<code>(.+?)<\/code>/ig, escapeCode(RegExp.$
+1)); 
        }
        
        while ( v.match(/<c>(.+?)<\/c>/i) )
        {
            v = v.replace(/<c>(.+?)<\/c>/ig, escapeCode(RegExp.$1));
        }
        
        v = v.replace(new RegExp(String.fromCharCode(222), 'g'), "\n")
+;

        
        Perlmonks.HtmlEditor.superclass.setValue.call(this, v);
    },
    
    getValue : function(){
        
        var v = Perlmonks.HtmlEditor.superclass.getValue.call(this);

        v = v.replace(/\n/g, String.fromCharCode(222));

        while ( v.match(/<pre class="code">(.+?)<\/pre>/) )
        {
            v = v.replace(/<pre class="code">(.+?)<\/pre>/g, deEscapeC
+ode(RegExp.$1));
        }

        v = v.replace(new RegExp(String.fromCharCode(222), 'g'), "\n")
+;

        return v;
    },
    
    getDocMarkup : function(){
        return '<html><head><style type="text/css">body{border:0;margi
+n:0;padding:3px;height:98%;cursor:text;} .code { font-family: Courier
+, "Courier New", monospace }</style></head><body></body></html>';
    }
    

});

function deEscapeCode (txt)
{
    txt = txt.replace(/&lt;/g, '<'); txt = txt.replace(/&gt;/g, '>');
    txt = txt.replace(/<br>/g, "\n");
    return String.format("<code>{0}</code>", txt);
}

function escapeCode (txt)
{
    txt = txt.replace(/</g, '&lt;'); txt = txt.replace(/>/g, '&gt;');
    
    return String.format('<pre class="code">{0}</pre>', txt);
}

function find_my_ta ()
{
    var a = document.getElementsByTagName('textarea');

    for (var i=0; i<a.length;i++)
    {
        var m = a.item(i).attributes;
        
        for (var j=0; j<m.length; j++)
        {
            if ( m.item(j).nodeName=="name" && String(m.item(j).nodeVa

            {
                return a.item(i);
            }
        }
    }

Ext.get('show_html_edit').dom.onclick = function (event)

    try
    {
        ed.show();
    }
    catch (e)
    {
        alert(e);
    }
    
    return false;
};

    Of course, since time has elapsed between versions of all of the above, tweaking may be needed. YMMV.

    HTH,

      What's the current status of this? Does anyone have it working?

      Thanks...
