validating FCKeditor

Question

hi, how can FCKeditor be validated for required field using javascript.

Answer 1

Use FireBug, and see what hidden textarea it is updating. Then check that element.

if (document.getElementById('fckinstance').innerHTML === '') {
    alert('required field');
}

That is just an example. It probably doesn't use an id like that either, because of multiple instances on the same page.

The textarea that FCKeditor replaces is probably the one that holds its HTML.

Note too, the FCKeditor can seem blank, even though there is HTML in it.

Answer 2

Try this,

var EditorInstance = FCKeditorAPI.GetInstance('message') ; 
if(EditorInstance.EditorDocument.body.innerText.length<=0)
{
alert("This firld is mandatory");
EditorInstance.EditorDocument.body.focus();
return false;
}
