Get tinymce input and alert() it

I am just building a form with multiple steps. On step 3, I have a tinymce editor. On step 4 I want to generate a preview of the input from tinymce. I have problems, to get the the contents form the tinymce input box. This is my current code开发者_如何学Go:

jQuery('#next_is_preview').click(function(){
alert(jQuery("#content_ifr").contents().find("#tinymce").html());
});

Currently it returns null. What could be the issue?

Probably safest to use the TinyMCE API to get the contents i.e.

alert(tinyMCE.activeEditor.getContent());

Does this work?

jQuery('#next_is_preview').click(function(){ 
    alert(("#tinymce").html()); 
}); 

Use the API and your editors id (you used 'content')

alert(tinyMCE.get('content').getContent());

Your snippet is working for me! I used it to copy from a tinymce textarea to another one and your code did the trick perfectly:

$("#copyBtn").click(function(e){
    e.preventDefault();
    $("#spanish_ifr").contents().find("#tinymce").html($("#english_ifr").contents().find("#tinymce").html())));
});
