jquery - Dealing with line Breaks on contentEditable DIV

Question

I have a problem with contenteditable line breaks on SAFARI/CHROME. When I press "return" on a contentEditable <div>, instead of creating a <br> (like Firefox), they create a new <div>:

<div>Something</div>
<div>Something</div>

That looks like (on the contentEditable DIV):

Something
Something

But after sanitization (removing <div>), I get this:

SomethingSomething

In Firefox, the contenteditable is:

Something
<br>
Something

And that after sanitization looks the same:

Something
Something

Is there any solution to "normalize" this across browsers?

I've found this code on Make a <br> instead of <div></div> by pressing Enter on a contenteditable

$(function(){

  $("#editable")

  // make sure br is always the lastChild of contenteditable
  .live("keyup mouseup", function(){
    if (!this.lastChild || this.lastChild.nodeName.toLowerCase() != "br") {
      this.appendChild(document.createChild("br"));
     }
  })

  // use br instead of div div
  .live("keypress", function(e){
    if (e.which == 13) {
      if (window.getSelection) {
        var selection = window.getSelection(),
          range = selection.getRangeAt(0),
          br = document.createElement("br");
        range.deleteContents();
        range.insertNode(br);
        range.setStartAfter(br);
        range.setEndAfter(br);
        range.collapse(false);
        selection.removeAllRanges();
        selection.addRange(range);
        return false;
      }
    }
  });
});

This works, but (in SAFARI and CHROME) I have to press two times the "return" key to get a new line...

Any idea?

Edit: With the code I found ( at the bottom of this question) is working fine except the function that "makes sure a <br> element is always the lastChild... Any idea on how to fix this?

Edit 2: I'm getting this error on the console: Uncaught TypeError: Object #<HTMLDocument> has no method 'createChild'

Edit 3: Ok, I changed the document.createChild("br"); to document.createElement("br"); and I think I got it working in FF/Safari/Chrome... All return <br> for new lines...

The problem is now that when I'm inside an Ordered or Unordered List, I need to get a new line without <br>...

Edit 4: If anyone interested in the solution of the last edit: Avoid createElement function if it's inside a <LI> element (contentEditable)

Answer 1

This technique appears to avoid the Chrome bug that does show BRs the first time (with the code you mentionned you need to push two times the Enter key).

It's not a perfect hack but it works: it adds a whitespace after your BR so it show properly. However, you will see that adding only a whitespace " " will NOT change anything, it works with other letters. The browser will not show it, probably because it is like a blank space inside an html page, it simply does not mean anything. To get rid of that bug I created a div with jQuery that includes a   tag, and I take the text() property to put it in the textnode otherwise it doesn't work.

$editables = $('[contenteditable=true]');

$editables.filter("p,span").on('keypress',function(e){
 if(e.keyCode==13){ //enter && shift

  e.preventDefault(); //Prevent default browser behavior
  if (window.getSelection) {
      var selection = window.getSelection(),
          range = selection.getRangeAt(0),
          br = document.createElement("br"),
          textNode = document.createTextNode("u00a0"); //Passing " " directly will not end up being shown correctly
      range.deleteContents();//required or not?
      range.insertNode(br);
      range.collapse(false);
      range.insertNode(textNode);
      range.selectNodeContents(textNode);

      selection.removeAllRanges();
      selection.addRange(range);
      return false;
  }

   }
});
