Setting up the Editors HTML

Setting up the Editor's HTML is done by creating a textarea control on the page.

1<button type="button" id="toggleEditor">Toggle Editor</button> 
2<form method="post" action="#" id="form1"> 
3<textarea id="editor" name="editor" rows="20" cols="75"> 
4This is some more test text.<br>This is some more test text.<br>This is some more test text.<br> 
5This is some more test text.<br>This is some more test text.<br>This is some more test text. 
6</textarea> 
7</form> 
view plain | print | ?

Setting up the Editors Javascript

Once the textarea is on the page, then initialize the Editor like this:

1(function() { 
2    //Setup some private variables 
3    var Dom = YAHOO.util.Dom, 
4        Event = YAHOO.util.Event; 
5 
6        //The Editor config 
7        var myConfig = { 
8            height: '300px', 
9            width: '600px', 
10            animate: true, 
11            dompath: true, 
12            focusAtStart: true 
13        }; 
14 
15    //Now let's load the Editor.. 
16    var myEditor = new YAHOO.widget.Editor('editor', myConfig); 
17    myEditor.render(); 
18})(); 
view plain | print | ?

Using the config option autoHeight

The Editor will now grow and shrink in height to match the content inside. It will never shrink smaller than the current height config option.

1(function() { 
2    //Setup some private variables 
3    var Dom = YAHOO.util.Dom, 
4        Event = YAHOO.util.Event; 
5 
6        //The Editor config 
7        var myConfig = { 
8            height: '300px', 
9            width: '600px', 
10            animate: true, 
11            dompath: true, 
12            focusAtStart: true, 
13            autoHeight: true 
14        }; 
15 
16    //Now let's load the Editor.. 
17    var myEditor = new YAHOO.widget.Editor('editor', myConfig); 
18    myEditor.render(); 
19})();
