jQuery_serialize（form表单序列化）用于在前端要传很多值往后端的时候：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="/static/jquery-3.2.1.min.js"></script>
</head>
<body>
<form name="myForm" action="http://www.365mini.com" method="post">
{% csrf_token %}
<input name="uid" type="hidden" value="1" />
<input name="username" type="text" value="张三" />
<input name="password" type="text" value="123456" />
<select name="grade" id="grade">
<option value="1">一年级</option>
<option value="2">二年级</option>
<option value="3" selected="selected">三年级</option>
<option value="4">四年级</option>
<option value="5">五年级</option>
<option value="6">六年级</option>
</select>
<input name="sex" type="radio" checked="checked" value="1" />男
<input name="sex" type="radio" value="0" />女
<input name="hobby" type="checkbox" checked="checked" value="1" />游泳
<input name="hobby" type="checkbox" checked="checked" value="2" />跑步
<input name="hobby" type="checkbox" value="3" />羽毛球
<input name="btn" id="btn" type="button" value="点击" />
{#<button class="send_ajax">send_Ajax</button><span class="login_error"></span>#}
<script>
$("#btn").click(function () {
$.ajax({
url:"/demo2/",
type:"POST",
data:$("form").serialize(),
success:function (data) {
alert(data)
}
})
}) </script>
</body>
</html>
