[ASP.Net] Cannot Send "&" with XMLHttpRequest

[ak1dnar]

When I am sending a form Input like in this format using ajax to my ASP.Net page;
term=ASP & PHP

Using This JavaScript;

function myFunc(term_from_form){
var qstring = "term="+term_from_form; // ASP & PHP
url = 'ServerPage.aspx';
setParams(url,qstring)
}
function setParams(url,params){
      makeobj(); // Creating http_request here
      http_request.onreadystatechange = buildOutPut;
      http_request.open('POST', url, true);
      http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
      http_request.setRequestHeader("Content-length", params.length);
      http_request.setRequestHeader("Connection", "close");
      http_request.send(params);
}

Only "ASP" part is getting,"& PHP" part is missing.

Dim SearchTerm As String = Request.Form("term")

the remaining part of the string is missing.(after the "&")
How to fix this? Thanks.

params are sent in the format of:
key1=value1&key 2=value2

So by straight using the the & you make it think that the "PHP" part is a new "key".
Try calling the escape() function onr your string first.

function setParams(url,params){
      makeobj();
      alert(params) //term=ABC & DEF&area=London 
      var encodedInputString =escape(params);
      alert(encodedInputString) //term%3DABC%20%26%20DEF%26area%3DLondon
      http_request.onreadystatechange = buildOutPut;
      http_request.open('POST', url, true);
      http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
      http_request.setRequestHeader("Content-length", encodedInputString.length);
      http_request.setRequestHeader("Connection", "close");
      http_request.send(encodedInputString);
}
 

I tried that also. but see my sample Input String here. For that String the server side response is like this.

Dim SearchTerm As String = Request.Form("term") ' Nothing
Dim area As String = Request.Form("area") ' Nothing
 

Is that mean ASP.net is not reading this line ?
//term%3DABC%20%2 6%20DEF%26area% 3DLondon

Hmm I guess it is escaping TOO much, as it escapes the = signs and stuff too.
Try calling escape() on just parts
so like "key="+escape(v alue)+"&key2="+ escape(value2) (etc..)
