问题描述



我正在为一个网站制作一个邮件系统,想要一个漂亮的接收器输入字段,其中添加的接收器被包含并添加到输入文本字段的值。目前,我在span-container中显示添加的接收器时,使用单独的添加字段。我想将它们合并到一起。就像常规电子邮件软件中的任何输入字段一样。



帮助将不胜感激!感谢提前!

解决方案

简答:不,您不能包含< span />在< input />内。



您有几个选项。您可以使用javascript来模拟行为,如电子邮件至:字段。例如。聆听按键,并处理一个后退的动作;。



另一个选项是使列表(css样式)像一个文本框。拥有最后一个< li />包含一个带有清除样式的文本框。每次用户添加新的电子邮件,然后插入一个新的< li />在文本框之前。



EG



html:

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

css:

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

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

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

javascript(jQuery,可以更改为香草)

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

您将需要扩展此JavaScript以包含一个按键处理程序等,但它给出了一般的想法。

任何选项都需要一些javascript。



如果可以使用jQuery您可以查看 jQuery UI自动填充


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!

解决方案

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
