从表单创建并发送电子邮件+保持javascript过滤器

Question

在联系页面上，我有一个表单，允许用户向公司发送电子邮件。为了控制每个字段，我有一个表单脚本和一些CSS效果。

这很完美。 这是DEMO（遗憾的是，它无法在jsfidle上运行）

但是，我没有找到任何使用javascript发送电子邮件的解决方案（不可能）。但是我需要做些什么来保持我的javascript功能并发送这封电子邮件？

注意：发送电子邮件后，用户必须保持同一页面。

HTML

<form onSubmit="return formValidation();" id="contactForm" name="contactForm" action="index.php">
    <ul>
        <label for="name">Name <span id="required">*</span></label>
        <li><input name="name" id="name" type="text"/></li>
    </ul>
    <ul>
        <label for="telephone">Telephone <span id="required">*</span></label>
        <li><input name="telephone" id="telephone" type="text"/></li>
    </ul>
    <ul>
        <label for="email">Email <span id="required">*</span></label>
        <li><input name="email" id="email" type="text"></li>

    <ul id="row_submit_button">

    <ul id="form_incorect_message">
