如何使用html表单数据发送JSON对象 [英] How to send a JSON object using html form data
问题描述
< html>
< head>< title> test< / title>< / head>
< body>
< form action =myurlmethod =POSTname =myForm>
< p>< label for =first_name>名字:< / label>
< input type =textname =first_nameid =fname>< / p>
< p>< label for =last_name>姓氏:< / label>
< input type =textname =last_nameid =lname>< / p>
< input value =Submittype =submitonclick =submitform()>
< / form>
< / body>
< / html>
当用户将此表单的数据作为JSON对象发送到我的服务器时,这将是最简单的方法点击提交?
更新:
我已经走到尽头,但它似乎不工作:
< script type =text / javascript>
函数submitform(){
alert(Sending Json);
var xhr = new XMLHttpRequest();
xhr.open(form.method,form.action,true);
xhr.setRequestHeader('Content-Type','application / json; charset = UTF-8');
var j = {
first_name:binchen,
last_name:heris,
};
xhr.send(JSON.stringify(j));
我做错了什么?
以数组形式获取完整的表单数据并对其进行字符串化。
var formData = JSON。字符串化($( #myForm会)serializeArray());
您可以稍后在ajax中使用它。或者如果你不使用ajax;把它放在隐藏的textarea并传递给服务器。如果这些数据是通过普通表单数据作为json字符串传递的,那么您必须使用 json_decode 进行解码。然后你将得到一个数组中的所有数据。
$。ajax({
type:POST,
url:serverUrl,
data:formData,
success:function(){},
dataType:json,
contentType:application / json
});
So I've got this HTML form:
<html>
<head><title>test</title></head>
<body>
<form action="myurl" method="POST" name="myForm">
<p><label for="first_name">First Name:</label>
<input type="text" name="first_name" id="fname"></p>
<p><label for="last_name">Last Name:</label>
<input type="text" name="last_name" id="lname"></p>
<input value="Submit" type="submit" onclick="submitform()">
</form>
</body>
</html>
Which would be the easiest way to send this form's data as a JSON object to my server when a user clicks on submit?
UPDATE: I've gone as far as this but it doesn't seem to work:
<script type="text/javascript">
function submitform(){
alert("Sending Json");
var xhr = new XMLHttpRequest();
xhr.open(form.method, form.action, true);
xhr.setRequestHeader('Content-Type', 'application/json; charset=UTF-8');
var j = {
"first_name":"binchen",
"last_name":"heris",
};
xhr.send(JSON.stringify(j));
What am I doing wrong?
Get complete form data as array and json stringify it.
var formData = JSON.stringify($("#myForm").serializeArray());
You can use it later in ajax. Or if you are not using ajax; put it in hidden textarea and pass to server. If this data is passed as json string via normal form data then you have to decode it using json_decode. You'll then get all data in an array.
$.ajax({
type: "POST",
url: "serverUrl",
data: formData,
success: function(){},
dataType: "json",
contentType : "application/json"
});
