Run text input

I noticed a new way to post status comments on Facebook. Basically, when you write your comment, you don’t have buttons for a click, but an enter key to click to send a comment. Now I would like to do that too. And I was thinking about possible solutions. It occurs to me that they are <input>sent with the enter button pressed, but this text field is not.

  • Or I write input (type of text) and set the upper caps of the height more than the line
  • Or I need to add a text box and somehow submit this form when the user presses the enter key.

What's better? And if the answer = second, how can I do this?

No need to create a framework (e.g. jQuery) just for this:

var textarea = document.getElementById("area");

try {
    textarea.addEventListener("keydown", keyPress, false);
} catch (e) {
    textarea.attachEvent("onkeydown", keyPress);
}

function keyPress(e) {
    if (e.keyCode === 13) {
        alert("Enter key was pressed")
    } else {
        return;
    }
}

Take a look at an example here: http://fiddle.jshell.net/yuCAd/3/

I would go with the second. And it will use javascript to intercept the input key, and then call the function to send. This answer should do the following: Run a button click using JavaScript on the Enter key in the text box
