Why doesn't my connection to neo4j work (through Javascript) - javascript

I am trying to make a interaction with my local neo4j dataset through javascript. But I get this error:
Uncaught SyntaxError: Unexpected token : (13:20:43:754 | error, javascript)
at http://localhost:7474/?callback=jQuery111107695061936974525_1417522841327&{%22statements%22:[{%22statement%22:%22MATCH%20(n)%20RETURN%20count(n)%22}]}&_=1417522841328:2
success (13:20:43:958)
at public_html/index.html:34
I.e. I want to sent and receive queries with a web application.
This is my code by now:
<head>
<title>TODO supply a title</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script language="javascript" type="text/javascript" src="js/jquery-1.11.1.js"></script>
<script type="text/javascript">
var body = JSON.stringify({
statements: [{
statement: 'MATCH (n) RETURN count(n)'
}]
});
$.ajax({
url: "http://localhost:7474",
type: "POST",
data: body,
dataType: "jsonp",
contentType: "application/jsonp"
})
.done(function(result){
console.log(result);
})
.fail(function(error){
console.log(error.statusText);
}); </script>
</head>

It's not working because you're POSTing to the wrong endpoint. Note your URL
Here are the docs.
It should probably be this:
$.ajax({
url: "http://localhost:7474/db/data/transaction/commit",
type: "POST",
data: body,
dataType: "jsonp",
contentType: "application/jsonp"
})

Posting a JSon object to Webservice via AJAX

I'm trying to send an object in JSon format to my Java backend by AJAX, but I was unsuccessful.
I wonder if the syntax is properly correct.
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="scripts/jquery.min.js.download"></script>
<script src="scripts/jquery.imagemapster.js.download"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
var myJSon = {"name":"Jo","age":30,"city":"Ny"};
$.ajax({
type: "POST",
url: 'http://localhost:8080/Servidor/server',
//contentType: "application/json;charset=utf-8",
dataType: "json",
data: JSON.stringify(myJSon),
success: function (data){
alert('Sucess');
},
error: function () {
alert('Error');
}
});
});
});
</script>
</head>
<body>
<button>Send an HTTP POST request to a page and get the result back</button>
</body>
</html>
When the line contentType: "application/json;charset=utf-8" is not commented out, I get the following error in the backend: INFO: Could not find grammar element for class java.lang.String
Is the syntax correct? Can the error be from the backend itself?
P.S.: Sorry for my bad english
Your code is good, you just misspelled "success" on the AJAX call (you need 2 letter c's instead of 1). So replace sucess: function(data){...} with success: function(data){...} https://jsfiddle.net/stephentillman/aow5pah2/

AJAX problems with sending POST, and getting result

Im new at JS and JSON. So I need to send a JSON massive to Google API using POST, and get the answer and show it via alert. I wrote this page, but this code has no result.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

<script type="text/javascript">
$.ajax({

data: '{wifiAccessPoints:["macAddress", "signalStrength"], cellTowers:["cellId", "locationAreaCode", "mobileCountryCode", "mobileNetworkCode"]}',
dataType: "json",
success: function(response) {
alert(response);
}
});
</script>
</body>
</html>
When using AJAX you require to set the content-type of the information you are sending. By default this value is set to application/x-www-form-urlencoded; charset=UTF-8.
$.ajax({
type: "POST",
url: 'https://www.googleapis.com/geolocation/v1/geolocate?key=KEY',
data: JSON.stringify({wifiAccessPoints:["macAddress", "signalStrength"], cellTowers:["cellId", "locationAreaCode", "mobileCountryCode", "mobileNetworkCode"]}),
contentType: "json",
success: function(response) {
alert(response);
}
});
Are you sending the response in JSON format? datatype property refers to the type that you're returning from the server. And if that doesn't match, control will go the error callback. Remove or update the datatype property to match the response type. Make the below changes and try
$.ajax({
type: "POST",
url: 'https://www.googleapis.com/geolocation/v1/geolocate?key=KEY',
data: '{wifiAccessPoints:["macAddress", "signalStrength"], cellTowers:["cellId", "locationAreaCode", "mobileCountryCode", "mobileNetworkCode"]}',
success: function(response) {
alert(response);
},
error: function(jqXHR, textStatus, errorThrown) {
alert("error");
}
});

Why is the array undefined
My question is how do i get to display the objects inside the results array. I've tried console.log(data.results[0].bodyColor) and i get an error. When i try (data.results) i get undefined. when i try (data.results[0]) it gives responds with a error message. Why is the array undefined when i can see it on my console. [this is the console so how can i print out the value of the AirBagLocFront][1]

You have a typo in your code. You want Results, not results. Moreover, Results is an array containing a single object. You could traverse the entire data structure quite easily using a for...in loop. Here is a working snippet:
$.ajax({
url: "https://vpic.nhtsa.dot.gov/api/vehicles/DecodeVINValuesBatch/",
type: "POST",
cache: true,
data: {
format: "json",
data: "WBAPK5C52AA599960;"
},
dataType: "json",
success: function(data) {
var res = data.Results[0];
for (var prop in res) {
if (res.hasOwnProperty(prop)) {
console.log(prop + ' - ' + (res[prop] ? res[prop] : 'N/A'));
}
}
}
});

}

This works the syntax i was using to access the nested object was incorrect. Thanks everyone.

How to submit JSON Data by Request Body in jQuery?

I am not expert in jQuery, consider me fresher. Here is my code which one not responsible for jQuery JSON data submission by Request Body.
<!doctype html>
<html lang="en">
<head>
<title>jQuery Data submitted by JSON Body Request</title>
<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">
$.ajax({
url : "/",
type: "POST",
data: [
{id: 1, name: "Shahed"},
{id: 2, name: "Hossain"}
],
contentType: "application/json; charset=utf-8",
dataType : "json",
success : function(){
console.log("Pure jQuery Pure JS object");
}
});
</script>
</head>
<body>
<p>
Example of submission JS Object by JSON Body Request<br/>
Its could submitted mass amount of data by Message body<br/>
It's secured and faster than any data submission .
</p>
</body>
</html>
Post Source appeared:
Shahed=undefined&Hossain=undefined
But desired Post Source is:
[{"id":1,"name":"Shahed"},{"id":2,"name":"Hossain"}]
How do I get the desired Post Source for each Request Body?
Here is the right code for your desired out put.
$.ajax({
url : "/",
type: "POST",
data: JSON.stringify([
{id: 1, name: "Shahed"},
{id: 2, name: "Hossain"}
]),
contentType: "application/json; charset=utf-8",
dataType : "json",
success : function(){
console.log("Pure jQuery Pure JS object");
}
});
Your must convert JS Object to String and JSON.stringify(JSObject) is the method responsible for that.

Jquery Unable to make Ajax Request to Server

I am trying to make an AJAX Request through JQuery
The below is my code .
But when i debugged through Mozilla Firebug i observed that ,there is no Request hitting to the Server .
Could anybody please tell me where i am doing wrong .
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JQuery Example</title>
</head>
<body>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$.ajax({
url: 'ajax/balances',
processData: false,
timeout: 10000,
type: "POST",
contentType: "application/xml",
dataType: "json",
data: '<MyReq user="' + User + '" katha="' + ivalitiKatha + '" />',
success: function(data) {
},
error : function() {
alert("Sorry, The requested property could not be found.");
}
});
});
</script>
</body>
</html>
This is my web.xml on server side
<servlet-mapping>
<servlet-name>Jersey Web Application</servlet-name>
<url-pattern>/ajax/*</url-pattern>
</servlet-mapping>
Maybe adding <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> to the head instead of the body helps!
First of all I would recommend moving the CDN JQuery into the head section of the website.
Secondly I have tested the code above and the issue looks to lie with the (data) you are posting in the JSON / AJAX request.
If you remove it or amend to JSON the request returns a result e.g.
$.ajax({
url: 'test',
processData: false,
timeout: 10000,
type: "POST",
contentType: "application/json",
dataType: "json",
data: '{"foo": "bar"}',
success: function(data) {
alert('Success');
},
error : function() {
alert("Sorry, The requested property could not be found.");
}
});​
You will need to format the data as a JSON request
data: '{"foo": "bar"}',
Hope this helps
