我试图将数据POST到REST api而不使用
AJAX.我想以
JSON格式发送数据.我有以下代码,但我试图找出如何转换输入字段和POST到服务器.这是我的代码尝试：
- <form id = "myform" method = "post">
- id: <input type = "text" id = "user_id" name = "user_id">
- data: <input type = "text" id = "user_data" name = "user_data">
- <input type = "button" id = "submit" value = "submit" onClick='submitform()'>
- </form>
- <script language ="javascript" type = "text/javascript" >
- function submitform()
- {
- var url = '/users/' + $('#user_id').val();
- $('#myform').attr('action',url);
- //
- // I think I can use JSON.stringify({"userdata":$('#user_data').val()})
- // to get the data into JSON format but how do I post it using js?
- //
- $("#myform").submit();
- }
解决方法
您可以添加一个隐藏的输入字段与json值,像这样 –
- function submitform() {
- var url = '/users/' + $('#user_id').val();
- $('#myform').attr('action',url);
- var data = JSON.stringify({
- "userdata": $('#user_data').val()
- })
- $('<input type="hidden" name="json"/>').val(data).appendTo('#myform');
- $("#myform").submit();
- }
你可以使用json参数(隐藏输入的名称)访问你的json
