How to Make an Editable Div Look Like a Text Field

How do I make an editable DIV look like a text field?

These look the same as their real counterparts in Safari, Chrome, and Firefox. They degrade gracefully and look OK in Opera and IE9, too.

Demo: http://jsfiddle.net/ThinkingStiff/AbKTQ/

CSS:

textarea {
    height: 28px;
    width: 400px;
}

#textarea {
    -moz-appearance: textfield-multiline;
    -webkit-appearance: textarea;
    border: 1px solid gray;
    font: medium -moz-fixed;
    font: -webkit-small-control;
    height: 28px;
    overflow: auto;
    padding: 2px;
    resize: both;
    width: 400px;
}

input {
    margin-top: 5px;
    width: 400px;
}

#input {
    -moz-appearance: textfield;
    -webkit-appearance: textfield;
    background-color: white;
    background-color: -moz-field;
    border: 1px solid darkgray;
    box-shadow: 1px 1px 1px 0 lightgray inset;  
    font: -moz-field;
    font: -webkit-small-control;
    margin-top: 5px;
    padding: 2px 3px;
    width: 398px;    
}

HTML:

<textarea>I am a textarea</textarea>
<div id="textarea" contenteditable>I look like textarea</div>

<input value="I am an input" />
<div id="input" contenteditable>I look like an input</div>

How to make a content editable div behave like a text area?

Edit

After the @Mr_Green comment above, you should have a look at Make a <br> instead of <div></div> by pressing Enter on a contenteditable

The JS code to make it right is :

$(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;
        }
      }
    });

})

;

You can intercept the Enter key press and replace it with a <br> with Javascript :

$(function(){
    
      $("#editable").keypress(function(e) {
        if (e.which == 13) {
            e.preventDefault();
            
             if (document.selection) {
                document.selection.createRange().pasteHTML("<br/>");
             } else {
                $(this).append("<br/>");
             }
        }
    });
});

How do I make a div element editable (like a textarea when I click it)?

Let's work through it.

You can't make a div editable. There's no such thing as an editable div, at least for now. So the problem is finding out what to use for editing instead. A textarea works perfectly. So the idea is to somehow get a textarea where the div currently sits.

The question is how and from where do we get the textarea. There are various ways, but one of them is to dynamically create a textarea on the fly:

var editableText = $("<textarea />");

and replace it with the div:

$("#myDiv").replaceWith(editableText);

The textarea is in place now. But it is empty and we have just replaced the div and lost everything. So we need to preserve the text of the div somehow. One way is to copy the text/html inside the div before replacing it:

var divHtml = $("#myDiv").html(); // or text(), whatever suits.

Once we have the html from the div, we can populate the textarea and safely replace the div with the textarea. And set the focus inside the textarea as the user might want to start editing. Combining all the work upto this point, we get:

// save the html within the div
var divHtml = $("#myDiv").html();
// create a dynamic textarea
var editableText = $("<textarea />");
// fill the textarea with the div's text
editableText.val(divHtml);
// replace the div with the textarea
$("#myDiv").replaceWith(editableText);
// editableText.focus();

It's functional but nothing happens when a user clicks a div because we didn't setup any events. Let's wire up the events. When the user clicks any div $("div").click(..), we create a click handler, and do all of the above.

$("div").click(function() {
    var divHtml = $(this).html(); // notice "this" instead of a specific #myDiv
    var editableText = $("<textarea />");
    editableText.val(divHtml);
    $(this).replaceWith(editableText);
    editableText.focus();
});

This is good, but we'd want a way to get our div back when a user clicks out or leaves the textarea. There is a blur event for form controls that is triggered when a user leaves the control. That can be used to detect when a user leaves the textarea, and replace back the div. We do the exact reverse this time. Preserve the value of textarea, create a dynamic div, set it's html, and replace out the textarea.

$(editableText).blur(function() {
    // Preserve the value of textarea
    var html = $(this).val();
    // create a dynamic div
    var viewableText = $("<div>");
    // set it's html 
    viewableText.html(html);
    // replace out the textarea
    $(this).replaceWith(viewableText);
});

Everything is great, except that this new div will no longer convert into a textarea on click. This is a newly created div, and we'll have to setup the click event again. We already have the entire code, but better than repeating it twice, it's better to make a function out of it.

function divClicked() {
    var divHtml = $(this).html();
    var editableText = $("<textarea />");
    editableText.val(divHtml);
    $(this).replaceWith(editableText);
    editableText.focus();
    // setup the blur event for this new textarea
    editableText.blur(editableTextBlurred);
}

Since the whole operation is two-way reversible, we'll need to do the same for the textarea. Let's convert that into a function too.

function editableTextBlurred() {
    var html = $(this).val();
    var viewableText = $("<div>");
    viewableText.html(html);
    $(this).replaceWith(viewableText);
    // setup the click event for this new div
    $(viewableText).click(divClicked);
}

Wiring up everything together, we have 2 functions, divClicked, editableTextBlurred and the line below triggers everything:

$("div").click(divClicked);

Checkout this code at http://jsfiddle.net/GeJkU/. This is not the best way of writing editable divs by any means, but just one way to start and approach the solution step by step. Honestly I have learnt just as much as you in writing this long piece. Signing off, adios!

How to make some text content in a div editable on click?

You should rework your logic a little. You should create separate input for every div element and in the events you should operate over current dblclicked or blured element through this. Here is JSFiddle demo with little modifications.

Hope it helps you. But I recommend to use contenteditable attribute as @apaul34208 suggested unless you have other custom js logic.

How to make an HTML div element editable cross-browser?

I found out how.

You use the contentEditable property of the DOMElement, like so

<div onClick="this.contentEditable='true';">
    lorem ipsum dolor lorem ipsum dolorlorem ipsum dolor
</div>

How to create a placeholder for DIV that act like textfield?

What I find in other answers is that when using :not(:focus) pseudo class, I have to click again in order to get the blinking cursor and be able to type. Such issue doesn't happen if I click on an area other than the placeholder.

My workaround is simply removing :not(:focus). Even though in this way the placeholder will still be there after I click on the editable div, I'm able to type no matter where in the div I click, and the placeholder disappears immediately after I type something.

BTW, I inspected YouTube's comment div implementation, seems they are doing the same thing, e.g. #contenteditable-root.yt-formatted-string[aria-label].yt-formatted-string:empty:before

.editableDiv1,
.editableDiv2 {
  border-bottom: 1px solid gray;
  outline: none;
  margin-top: 20px;
}

.editableDiv1[contentEditable="true"]:empty:not(:focus):before {
  content: attr(placeholder)
}

.editableDiv2[contentEditable="true"]:empty:before {
  content: attr(placeholder)
}

<div class="editableDiv1" contentEditable=true placeholder="If you click on this placeholder, you have to click again in order to get the blinking cursor and type..."></div>

<div class="editableDiv2" contentEditable=true placeholder="Click on placeholder is fine, it'll disappear after you type something..."></div>

function controlselectHandler(evt) {
    evt.preventDefault();
}
document.body.addEventListener('mscontrolselect', controlselectHandler);



$('#abc').on('click','input[type="text"]',function(e){
    $(this).focus();  
})
