Query String in AJAX

[Mary Cole]

Hi,
I am using AJAX to add rows to a specific section to my JSP page and when I add the rows I pass all the previously added rows data as a guery string to a struts action by an Ajax call. But when I add like 600 rows, it gives a JS error....is it coz of the limit in the query string length...how do I overcome this..pls advice...its urgent

Thx in advance

You have to use POST, you can not use get for large amounts of data.

  //Make sure object is supported
  if(req) {
    //Tell function to call for state changes
    req.onreadystatechange = processStateChange;
    //Give it the keys specifying GET or POST
    req.open("POST", url, true);
    //Since we are using GET no info to send
    req.send(null);
  }
  else{
    //inform user that it is not supported!
    alert("This browser lacks Ajax support!");
  }
   

Am using this...is this the correct way to use?

take the query string you append to the url and make it another variable.

url = "foo.com";
params = "a=123&b=456&c=789";

notice there is no ?, leave that off.

than your send method would look like

req.open("POST", url, true);
req.send(params);
