Put text in textbox

Is there a way to put text in a textbox but also allow the user to type something. I would like to write "username:" inside the box and allow the user to type after the colon. I can do this the hard way by creating a div right next to a textbox and make it look like they are one container, but I was wondering if there was an easier way? Thanks

EDIT: I don't want to text to disappear. I just want to user to be able to continue开发者_JS百科 typing

EDIT 2: the reason you cant put a value in the textbox is because its a form. when the user types a username next to the value it will submit together

HTML5 has a placeholder attribute you can now use:

<input type="text" placeholder="username" />

People have also created javascript functions that mimic this functionality.

There's also a jQuery placeholder plugin which does the same, if you'd like to go that route.

What's wrong with using standard HTML? You don't say that you need it to disappear...

<input type="text" value="username: " />

If you need it to disappear, use a placeholder attribute and a jQuery plugin as a fallback (for the browsers that don't support it.

You could do something like this:

<div>
    <label>Username:</label>
    <input type="text" />
</div>

CSS

div{border:1px solid gray;}
label{font-family:arial; font-size:.8em;}
input{border:none;}
input:focus{outline:none;}

Basically, created a containing div and placed a label and input in that div. label is the words that stay in the field. input has the border removed.

Fyi... you may need to increase the size of the input, depending on how many characters you want to accept.

<input type="text" placeholder="Category"/>

Maybe that can help you. If you want the textbox for only read you can put the property readonly = "".

You could call this javascript function once the page is loaded:

function add(text){
    var TheTextBox = document.getElementById("Mytextbox");
    TheTextBox.value = TheTextBox.value + text;
}

If you are using HTML5, you can use the placeholder attribute.
