第一步：拷贝下面的代码到你的html文件的<head>和</head>之间；<blockquote>
<form name="copy1">
<p><textarea rows="4" name="S1" cols="39" onMouseOver="this.focus()" onFocus="this.select()"><script language="JavaScript">
<!--function validate_form() {validity = true;if (!check_empty(document.form.NAME.value)){ validity = false; alert('没有填写姓名!'); }if (!check_email(document.form.EMAIL.value)){ validity = false; alert('Email地址错误!'); }if (!check_url(document.form.URL.value)){ validity = false; alert('主页网址错误!'); }if (!check_empty(document.form.DESCRIPTION.value)){ validity = false; alert('缺少内容简介!'); }if (validity)alert ("Needed entries have been verified. "+ "Your form is now being passed to your browser's "+ "Mail Delivery Sub-System.");return validity;}function check_empty(text) {return (text.length > 0); }function check_email(address) {if ((address == "")|| (address.indexOf ('@') == -1)|| (address.indexOf ('.') == -1))return false;return true;}function check_url(address) {if ((address == "")|| (address.indexOf ('http://') == -1)|| (address.indexOf ('.') == -1))return false;return true;}// -->
</script>
</textarea></p>
</form>
</blockquote>
<p>第二步：拷贝下面的代码到你的html文件的<body>和</body>之间；</p>
<blockquote>
<form name="copy2">
<p><textarea rows="4" name="S1" cols="39" onMouseOver="this.focus()" onFocus="this.select()"><form name="form" method="post"
action="mailto:alone@188.net?SUBJECT=友情连接" enctype="text/plain"
onSubmit="return validate_form()">
<p>姓名:<br>
<input type="text" size="40" name="NAME"><br>
Email地址:<br>
<input type="text" size="40" name="EMAIL"><br>
主页网址:<br>
<input type="text" size="40" name="URL" value="http://"><br>
内容简介:<br>
<textarea NAME="DESCRIPTION" ROWS="5" COLS="40" wrap="virtual"></textarea><br>
<input type="submit" name="submit" value="立刻发送"> <input type="reset"
value="重新填写"> </p>
</form>
</textarea></p>
</form>
</blockquote>
<p>说明：这个表单会检测姓名是否为空，email是否含"@""."，网址是否含"http""."，内容是否为空。是很有实用性的表单程序。将其中的mailto:的email地址修改成你自己的就可以用了。</p>
