How to express != in URLs

I wrote the following ajax call to fetch data using the nb (number of document view) parameter:
if ($("#fetch").hasClass("active")) {
$.ajax({
url: "ServletAjaxController",
type: "POST",
dataType: "json",
data: "c=" + controller + "&nb=300",
success: onSuccess,
contentType: "application/x-www-form-urlencoded;charset=UTF-8"
});
}
Now I want to do the same thing but expressing nb != 300 instead of the equal expression. Any IDEAs?

How to clean an XML object to avoid the "Content not allowed in prolog" error?

I have a XML object retrieved from an AJAX call and for which I have done some manipulations:
$.ajax({
url: "url_of_xml",
type: 'GET',
dataType: 'xml',
success: function (xml) {
var sld_doc= $(xml)
// manipulations with the XML file
}
})
The XML file is correctly modified and is how I need it to be (with the added/modified nodes). Now I need to POST the modified XML (to a GeoServer instance):
$.ajax({
url: "geoserver/rest/styles",
type: 'POST',
data: sld_doc,
headers: {
"Content-Type": "application/vnd.ogc.sld+xml"
},
dataType: 'json',
success: function (data) {a
console.log(JSON.stringify(data));
},
error: function (x, e) {
console.log(x.status + " " + x.responseText);
}
});
I'm getting the error: 500 org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.
From what I've read, it is caused by characters before the tag at the beginning of the XML doc.
How can I clean the begging of the XML object so that it can be sent correctly to the server ? I'm able to access nodes with sld_doc.find("node_name") but how can I check for invalid characters before the 1st node (<?xml>) ?

At the moment you are passing a jQuery object. Try unwrapping it, and setting the right dataType too:
$.ajax({
url: "geoserver/rest/styles",
type: 'POST',
data: sld_doc[0],
headers: {
"Content-Type": "application/vnd.ogc.sld+xml"
},
dataType: 'xml',
success: function (data) {a
console.log('success');
},
error: function (x, e) {
console.log('error');
}
});

Send data from a javascript ajax function to a jsp

This is what I am trying to do. On a home page.. say /home.jsp, a user clicks on a link. I read value of the link and on the basis of which I call a RESTful resource which in turn manipulates database and returns a response. Interaction with REST as expected happens with use of JavaScript. I have been able to get information from REST resource but now I want to send that data to another JSP.. say /info.jsp. I am unable to do this.
I was trying to make another ajax call within success function of parent Ajax call but nothing is happening. For example:
function dealInfo(aparameter){
var requestData = {
"dataType": "json",
"type" : "GET",
"url" : REST resource URL+aparameter,
};
var request = $.ajax(requestData);
request.success(function(data){
alert(something from data); //this is a success
//I cannot get into the below AJAX call
$.ajax({
"type": "post",
"url": "info.jsp"
success: function(data){
alert("here");
("#someDiv").html(data[0].deviceModel);
}
});
How do I go about achieving this? Should I use some other approach rather than two Ajax calls? Any help is appreciated. Thank You.

You can use the following function:
function dealInfo(aparameter) {
$.ajax({
url: 'thePage.jsp',
type: "GET",
cache: false,
dataType: 'json',
data: {'aparameter': aparameter},
success: function (data) {
alert(data); //or you can use console.log(data);
$.ajax({
url: 'info.jsp',
type: "POST",
cache: false,
data: {'oldValorFromFirstAjaxCall': data},
success: function (info) {
alert(info); //or you can use console.log(info);
$("#someDiv").html(info);
}
});
}
});
}
Or make the AJAX call synchronous:
function dealInfo(aparameter) {
var request = $.ajax({
async: false, //It's very important
cache: false,
url: 'thePage.jsp',
type: "GET",
dataType: 'json',
data: {'aparameter': aparameter}
}).responseText;
$.ajax({
url: 'info.jsp',
type: "POST",
cache: false,
data: {'oldValorFromFirstAjaxCall': request},
success: function (info) {
alert(info); //or you can use console.log(info);
$("#someDiv").html(info);
}
});
}

In this way I'm using.
"type": "post" instead of type: 'post'
Maybe it will help. Try it please. For Example;
$.ajax({
url: "yourURL",
type: 'GET',
data: form_data,
success: function (data) {
...
}
});

Ajax not being called in javascript function

In the success function I want to call a function. The problem is that ajax does not fire, so the data is never triggered and display. Here is my ajax call with a javascript function call in the success function.
$.ajax({
type: "POST",
url: "./api/login.php",
data: dataString,
cache: false,
success: function(data){
if(data){
//FUNCTION CALL WHEN USER LOGGING IN
retrieveUserBlogData();
window.location = "api/home.php";
}else{
$('.alert').show();
}
}
});
function retrieveUserBlogData(){
$.ajax({
type: "GET",
url: 'retrievePostData.php',
data: "",
dataType: 'json',
success: handleData
});
}
function handleData(data) {
alert(data);
var blog_file = data[3];
$('#imageDiv')
.append('<img id="blog_img" src="upload/' + blog_file + '"><br>');
}
I cant figure out why the ajax in the retrieveUserBlogData() function is not being triggered.
Any help would be appreciated Thanks.

Even if the AJAX succeeds, you are redirecting the browser to a different page after the first AJAX request:
window.location = "api/home.php";
So I would suggest removing that.

Try the following code for redirecting to another window
window.location.assign(URL);
then it may work.

Try it like this
$.ajax({
type: "POST",
url: "./api/login.php",
data: dataString,
cache: false,
success: function(data){
if(data){
//FUNCTION CALL WHEN USER LOGGING IN
retrieveUserBlogData();
}else{
$('.alert').show();
}
}
});
function retrieveUserBlogData(){
$.ajax({
type: "GET",
url: 'retrievePostData.php',
data: "",
dataType: 'json',
success: function(data){
alert(data);
var blog_file = data[3];
$('#imageDiv')
.append('<img id="blog_img" src="upload/' + blog_file + '"><br>');
window.location = "api/home.php";
}
});
}

trying to put an ajax request inside the success call back of another ajax request

I am trying to make two jQuery ajax calls, the second should be made from the success callback of the first. I have tried a couple variations of code e.g just messing with the brackets.
Here is what I tried.
$.ajax({
url: 'inc/grab_talk.php?name='+encoded_name+'&loc='+encoded_address+'&lat='+encoded_lat,
type: 'post',
success: function () {
$.ajax({
url: 'inc/talk_results.php',
type: 'post',
success: function (dat) {
alert(dat);
}
});
}
});
I am receiving '500 (internal server error) in console

Try this, you can use either POST or GET, but in your case GET seems to be more appropriate.
$.ajax({
type: "GET",
url: "some.php",
data: { name: "somename", location: "somelocation" },
success: function(){
$.ajax({
type: "GET",
url: "someother.php",
success: function(){
alert('test');
}
});
}
});

Check this example
$.ajax({
type: "post",
url: "ajax/example.php",
data: 'page='+btn_page,
success: function(data){
$.ajax({
var a=data; //edit data here
type: "post",
url: "example.php",
data: 'page='+a,
success: function(data){
});
});
