Span inside text input field?

问题

Is it somehow possible to place a span as the value of a text input field?

I am making a mailing system for a website and want a nice looking receivers input field, where added receivers are contained and added to the value of input text field. At the moment i use a separate "adding field" while showing added receivers in a span-container. I want to merge these to fields together. Just like any input field in regular e-mail software.

Help would be most appreciated! Thanks in advance!

Short answer: no, you cannot include a <span /> within an <input />.

You have a few options. You could use javascript to emulate behaviour like the email To: field. E.g. listen to key presses and handle actions like backspace after a ;.

Another option would be to make a list appear (css styled) like a textbox. Have the last <li /> contain a textbox with cleared styles. Every time the user adds a new email then insert a new <li /> before the textbox.

E.G.

html:

<ul class="email-textbox">
    <li>bob@email.com;</li>
    <li>jane@email.com;</li>
    <li><input type="text" /></li>
</ul>

css:

.email-textbox {
    background-color: #fff;
    border: 1px solid #ccc;
    padding: 2px 4px; 
}

.email-textbox li {
    display: inline-block;
    list-style: none;
    margin-left: 5px;   
}

.email-textbox input {
    background: none;
    border: none;
}

javascript (jQuery, can change to vanilla)

$(function () {
    $('.email-textbox').find('input').focus();
});

You will need to extend this javascript to include a keypress handler etc, but it gives the general idea.

Any option will require some javascript however.

If you can use jQuery, you could check out jQuery UI autocomplete

One way to do it would be to layer a text input on top of a div that is styled to look like a text input.

<div id="fake-input">
    <span class="input-item">John Doe</span>
    <span class="input-item">Jane Deere</span>
    <input id="receiver-input" type="text" />
</div>

You can strip all styling off of receiver-input, and add borders, background colors, and such to fake-input so that it appears to be a text field. When a receiver is added, you can create a new input-item span and append it to the list.

Input text fields are typically used to accept raw text input. Attempting to wrap input text inside of a text field opens you to user error and potential difficulties with parsing data if the person is able to manipulate the tags.

Personally I would suggest keeping your current method but enabling some form of AJAX support to make things more dynamic and less error-prone to the user.

TextExtjs is probably what you want. It's a jquery plugin for allowing removable tags with autocompletion etc in a textarea.

And here is a related SO discussion - where I found this plugin - on mimicking the similar behavior found in some inputs on facebook.
