提交没有表单的POST方法？

Question

I need to make a button with a similar functionality to "Follow" buttons in social networks. The thing is I need to refresh the page when the user clicks the button since the page content largely depends whether the user is following or not.

I could submit the "follow" with ajax and reload the page when ajax responds. Is it possible to submit data with POST without AJAX (like forms do)?

Answer 1

With JQuery you can do something like

$.post('pageurl.php', {"variable1": "Value1", "Variable2": "Value2"}, function(datareturn){});

And handle it from serverside like normal

$var1 = $_POST["varriable1"];

Answer 2

Depending on the amount of data to be submitted, a regular link can submit data as well.

This, for example, submits the search term this and that

https://www.google.com/search?q=this+and+that

Answer 3

you can create your form dynamically and then remove it:

function postjs (to,method, p) {
  var myForm = document.createElement("form");
  myForm.method=method;
  myForm.action = to ;
  for (var k in p) {
    var myInput = document.createElement("input") ;
    myInput.setAttribute("name", k) ;
    myInput.setAttribute("value", p[k]);
    myForm.appendChild(myInput) ;
  }
  document.body.appendChild(myForm) ;
  myForm.submit() ;
  document.body.removeChild(myForm) ;
}

and call it:

postjs('target.php','post',{field1:'value1',field2:'value2'})
