AJAX 请求未在 php 页面中发送完整数据

Question

I have been trying to post a status in my web application through AJAX which is sending a request to a PHP page and PHP page processes information furthermore.

function Upload_Status(id){
  var description=$('#Txt-editor').val();
  var data="q="+description;
  var xhr = new XMLHttpRequest();
  xhr.open('POST', 'status.php', true);
  xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
  xhr.onload = function () {
    var  response=this.responseText;
    if (!(response=="" || response==null)) {
      document.getElementById(id).innerHTML = response;
    }
  };
  xhr.send(data);
}

And status.php is

echo $_POST['q'];

which returns sometime half string and something quarter. I don't know what the problem is as I'm using a text editor, I also have changed editor but when this generates HTML code this creates the problem.

Any help?

Answer 1

I solved this questions myself. the problem was with the special symbols,commas and quotation signs etc. If i encrypt information sending from JS and decode JSON response and which return response from PHP i encode this response again to JSON, then this problem is solved :-)
