如何使 tinymce 粘贴在纯文本默认

EDIT: this solution is for version 3.x, for 4.x version read the answer from @Paulo Neves

The problem is that Paste plugin automatically resets plain text paste on every paste. So all we need to do - set it back. The following code should help.

tinyMCE.init({
...
oninit : "setPlainText",
plugins : "paste"


....
});

The definition of setPlainText

 function setPlainText() {
var ed = tinyMCE.get('elm1');


ed.pasteAsPlainText = true;


//adding handlers crossbrowser
if (tinymce.isOpera || /Firefox\/2/.test(navigator.userAgent)) {
ed.onKeyDown.add(function (ed, e) {
if (((tinymce.isMac ? e.metaKey : e.ctrlKey) && e.keyCode == 86) || (e.shiftKey && e.keyCode == 45))
ed.pasteAsPlainText = true;
});
} else {
ed.onPaste.addToTop(function (ed, e) {
ed.pasteAsPlainText = true;
});
}
}

So now it always will be plain.

I'm not sure this is possible, since "paste as plaintext" actually performs cleanup on the text before it adds it to the window. If you just paste data into the window, no operations can be done. (Unless you hooked into the onChange or something), but they you might end up fixing code that had already been pasted and thus, 'double fixing' it.

I have solved this problem with this code

tinyMCE.init({
...
plugins : "paste",
paste_text_sticky : true,
setup : function(ed) {
ed.onInit.add(function(ed) {
ed.pasteAsPlainText = true;
});
}
....
})

Isn't it better to use:

var ed = tinyMCE.activeEditor;

instead of:

var ed = tinyMCE.get('elm1');

Just ran into this one myself and discovered that as of TinyMCE 3.4.2 you can simply:

paste_text_sticky: true,
paste_text_sticky_default: true

...which was nice.

FYI, TinyMCE has improved this by implementing it as a default option in the paste plugin. More info: http://www.tinymce.com/wiki.php/Plugin:paste

However, it's still not perfect. So here is a script that also trips off all HTML:

// Paste
paste_auto_cleanup_on_paste : true,
paste_remove_spans: true,
paste_remove_styles: true,
paste_retain_style_properties: false,


paste_preprocess : function(pl, o)
{    // Replace <div> with <p>
o.content = o.content.replace(/<div>/gi, "<p>");
o.content = o.content.replace(/<\/div>/gi, "</p>");
o.content = o.content.replace(/<\r\n/gi, "\n");
o.content = o.content.replace(/<\n\n/gi, "\n");
o.content = o.content.replace(/<\n\n/gi, "\n");


// Replace empty styles
o.content = o.content.replace(/<style><\/style>/gi, "");


o.wordContent = true;
},


paste_postprocess : function(pl, o)
{    //console.log(o.node.innerHTML);
var ed = pl.editor, dom = ed.dom;


// Remove all tags which are not <p> or <br>
tinymce.each(dom.select('*', o.node), function(el)
{    if (el.tagName.toLowerCase() != "p" && el.tagName.toLowerCase() != "br")
{    dom.remove(el, 1); // 1 = KeepChildren
console.log(el.tagName);
}
dom.setAttrib(el, 'style', '');
});


},

I did as follows:

var pastePlainText = function() {
// No need to pass in an ID, instead fetch the first tinyMCE instance
var ed = tinyMCE.get(0);
ed.pasteAsPlainText = true;


//adding handlers crossbrowser
if (tinymce.isOpera || /Firefox\/2/.test(navigator.userAgent)) {
ed.onKeyDown.add(function (ed, e) {
if (((tinymce.isMac ? e.metaKey : e.ctrlKey) && e.keyCode == 86) || (e.shiftKey && e.keyCode == 45))
ed.pasteAsPlainText = true;
});
} else {
ed.onPaste.addToTop(function (ed, e) {
ed.pasteAsPlainText = true;
});
}
};

And then:

tinyMCE.init({
// ...
plugins: "paste",
oninit: pastePlainText // Note, without "
// ...
})

For the tinyMCE 3X or 4X things have change a little. now you can do this and it works fine.

tinymce.init({
plugins: "paste",
paste_as_text: true
});

I think the easiest way would be this:

tinymce.init({
...
paste_as_text: true,
plugins: "paste",
...
});

Without plug-in: Listen to paste event, get clipboard data

If you cannot use or do not want to use a plug-in for whatever reason, you can create your own "paste as plain text" callback function like so:

tinyMCE.init({


// ...,


setup: function (editor) {


// Listen for paste event, add "Paste as plain text" callback
editor.onPaste.add(function (editor, e) {


// Prevent default paste behavior
e.preventDefault();


// Check for clipboard data in various places for cross-browser compatibility.
// Get that data as text.
var content = ((e.originalEvent || e).clipboardData || window.clipboardData).getData('Text');


// Let TinyMCE do the heavy lifting for inserting that content into the editor.
editor.execCommand('mceInsertContent', false, content);
});
}
});

Note: This was created for TinyMCE 3.5.x. Compatibility may vary by version.

if you use a .yml file, add the plugin paste and paste_as_text: true

default:
plugins:
- paste
paste_as_text: true
