Question: I need to prevent the paste event of tinyMCE if the length of the current content of editor plus the length of the words to be pasted exceed the specified limit. How can I do it? Thank you.

Answer: 
I was wrong. I dont need to prevent or disable paste in tinyMCE to do this. I used their **paste** plugin and modified the content before it is pasted.

```
function(pl, o) {
      ...

      if(len > limit) {
           o.content = '';
      } 
}

```
Here is the solution:

```
paste_preprocess: function (plugin, args) {
    args.content = ''; // modify or do anything with the clipboard data
},

```

Do it inside, `init`
