Tinymce get content

问题

I try to get the content of tinymce, like this:

 var hallo = tinyMCE.activeEditor.getContent();
            alert(hallo);

but every time I get this message:

Uncaught TypeError: Cannot read property 'getContent' of null

I am using tinymce 4.

Thank you

Cannot read property 'getContent' of null often means that TinyMCE is unable to find your textbox which means there is something wrong in the reference to textarea's class.

<form method="post" action="somepage">
    <textarea id="myTextArea" class="mceEditor">I should buy a boat. </textarea>
</form>

<button onclick="content()">Get content</button>

Take note of mceEditor class which we will now inform the TinyMCE editor about :

<script type="text/javascript">

    tinyMCE.init({
        mode : "specific_textareas",
        editor_selector : "mceEditor"   //<<<---- 
    });

</script>

And now simply get the contents of that textbox on the button click.

function content() {
    alert(tinyMCE.get('myTextArea').getContent());
}

Here is working DEMO

You can get tinyMCE content by calling the the method triggerSave in the following way

tinyMCE.triggerSave();

after declaring this method you can get the contents by selector for example:-

var contents = $("#myTextArea").val();

or

var contents = tinyMCE.get('myTextArea').getContent();
