i'm using "div content editable" html to get value from input keyboard to post with ajax jquery and send to database.
this is my html code

```
<div class="form_field" name="contentbox" id="contentbox" contenteditable="true"> 

```

and my javascript

```
function mysubmit {
    var contentbox = $("#contentbox").html();
    var contentboxvalue = "contentboxvalue ='" + escape(contentbox) + "'";
    $.ajax({
        type: "POST",
        url: "<?php echo base_url() ?>admin/data",
        data: contentboxvalue,
        cache: true,
        success: function () {
            document.getElementById("contentboxInfo").innerHTML = contentbox;
        }
    });

}

```

But I have a problem when I'm updating the value in my database, example: `"hello world"`
and when I'm updating, ajax post jquery send value:

```
"
hello world"

```

How to remove linebreaks (CR/LF), but not `<br>` tags when submitting to database.
