My AJAX call isn't treating the data from server as JSON, even if i set the datatype in json:
function Getmateriasfromserver(callback){
var status_aux;
//Requisição HTTP, por dados provindos do url dado. Caso os dados recebidos sejam os esperados, entra no caso do SUCCESS
return $.ajax({
url: 'materiasphp/materias.php',
dateType: 'json',
success: function(data)
{
status_aux = data;
callback(status_aux);
var test = JSON.stringify(data);
console.log(data);
console.log(test[1]);
}
Console print test[1] = "["
You also have a typo in your code. dateType: should be dataType:
return $.ajax({
url: 'materiasphp/materias.php',
dataType: 'json',
...
var test = JSON.stringify(data);
Should probably be
var test = JSON.parse(data);
// or just
var test = data;
Because if you stringify it, then you are accessing letters in the string with bracket notation.
var test="cat":
console.log(test[0]);
Is c, the first letter in the string
JSON is a text based data format.
JSON.stringify(data); takes data and converts it to a JSON text, which it stores in a string.
console.log(test[1]); then reads the character at index 1 in that string and displays it.
This is normal behaviour.
If you want to deal with the data as a JavaScript data structure then don't convert it to JSON!.
Just work directly with the data structure in data.

When I try to get a External json object I receive "Uncaught SyntaxError: Unexpected token :" every time. I already tried use json and jsonp to get these values, but never works.

where is your JSON saved, it happened to me couple of days ago, i saved a JSON in database field, i had to save it like text, when i wanted to retrieve the value it returned with quotes "", and i was having the same error because quoted text is taken as string instead json, you have to check if the place where you are storing that json it '{JSON_CONTENT HERE}' if its stored like "'{}'", then is wrong.
It may be that your response is json and not jsonp. Try with dataType: "json"
var buttonOptions = {
gmap: map,
name: 'Download JSON File',
position: google.maps.ControlPosition.TOP_RIGHT,
action: function () {
$.ajax({
type:"GET",
contentType: "application/json; charset=utf-8",
url: "getJSON.php",
data: "{}",
//dataType: 'json',
cache:false,
success: function(data){
}
});
}
}
I have a button that returns the JSON file below

My question is, how am I going to loop and display each field in the Success function? I tried using $.each to no avail. Also how can I count each value. I used $('#msg').html(data.length);, however it is counting each character in the JSON file, instead of the actual value. Thanks.
I used $('#msg').html(data.lenght);, but it is counting each character in the JSON file, instead of the actual value.
It's quite evident because you haven't parsed the JSON yet, so data is evaluated as a string here.
Solution:
You need to parse the JSON data before trying to access it. So your code need to be like this:
success: function(data){
data = JSON.parse(data);
$('#msg').html(data.length);
}
how am I going to loop and display each field in the Success function?
And then you can loop over dataafter it's parsed with .each():
success: function(data){
data = JSON.parse(data);
$('#msg').html(data.length);
data.each(function(){
//Your code here
});
}
Edit:
Another thing in your Ajax call why are you using url: "getJSON.php"? In that case the Ajax call will just load the content of the PHP file as a string.
In the URL you should put your .json file or a web service that returns a JSON string.

As #chsdk said data is returned being as a string instead of a Javascript object you may want to take a look at $.getJSON() instead of $.ajax() for iterating over JSON objects
$.getJSON( "getJSON.php", function( data ) {
var count = data.length;
$.each( data, function( key, val ) {
//perform operations on data
});

I am having trouble in sending a JSON array in an AJAX call. Following is my Code
var company_name = $('input#company_name').val();
var company_localname = $('input#company_localname').val();
var companytype = $('#companytype').val();
if (companytype == 'retailer') {
var bank_name = $('input#bank_name').val();
var account_title = $('input#account_title').val();
var business_nature = $('input#business_nature').val();
var gross_sales = $('input#gross_sales').val();
}
After getting all the values I am storing the data in Json like the following
var jsonArray = [];
jsonArray["company_name"] = company_name;
jsonArray["company_localname "] = company_localname;
if (companytype == 'retailer') {
jsonArray["bank_name"] = bank_name;
jsonArray["account_title"] = account_title;
jsonArray["business_nature"] = business_nature;
jsonArray["gross_sales"] = gross_sales;
}
Now for sending the jsonArray in Ajax call
$.ajax({
url : url,
type : "POST",
dataType : 'json',
contentType : 'application/json; charset=UTF-8',
data : JSON.stringify(jsonArray),
success : function(response) {
//Some Code here
}
});
Please help me sending data. Or tell me if I am making any mistake here. Thank you
In JavaScript / JSON arrays are 0 based indexed data structures. What you are using here is more like a Map:
var jsonArray = [];
jsonArray["company_name"]=company_name ;
In JavaScript you cannot use arrays like this (well you can, but it is probably not what you want). For a data structure like a map that maps strings to objects rather then an index to objects, just use an object.
Or in short: Use var jsonArray = {}; rather than var jsonArray = []; The {} will create an object that you can assign properties to like you did. And JSON.stringify will correctly translate this into a JSON string like this:
{ "property": value, "otherProperty", otherValue }
Do something like this.
$.ajax({
url: url,
type: "POST",
dataType: 'json',
contentType: 'application/json; charset=UTF-8',
data: JSON.parse(JSON.stringify(jsonArray)),
success: function(response) {
//Some Code here
}
});
The JSON.parse() method parses a string as JSON, optionally transforming the value produced by parsing. Read more about JSON.parse() method
The JSON.stringify() method converts a JavaScript value to a JSON string. Read more about JSON.stringify() method
Here simply you can send an array and Parse it in server side.
$.ajax({
url : url,
type : "POST",
dataType : 'json',
data : jsonArray,
success : function(response) {
//Some Code here
}
});
i try to use ajxt to send post request to my restful service
here is my ajax code
var lat = marker.getPosition().lat();
var lng = marker.getPosition().lng();
//xmlhttp.open("GET","http://192.168.1.100:8080/MapDemo/service/add?name=hieugie333&longitude=123&latitude=321",true);
//xmlhttp.send();
//document.getElementById("message").innerHTML=xmlhttp.responseText;
var JSONObject= {"name":name, "longitude":lng,"latitude":lat };
var jsonData = JSON.parse( JSONObject );
var request = $.ajax({
url: "http://192.168.1.100:8080/MapDemo/service/add",
type: "POST",
contentType: "application/json; charset=utf-8",
data: jsonData,
dataType: "json"
});
can anyone help me in this case ?
var JSONObject= {"name":name, "longitude":lng,"latitude":lat };
That is a JavaScript object, not a JSON text.
var jsonData = JSON.parse( JSONObject );
That will error (or return null) because you aren't passing it a string containing a JSON text.
Your later code is expecting a string containing a JSON text though.
You want JSON.stringify not JSON.parse.
You need to change your "JSON.parse" to "JSON.stringify". You called the opposite function that you should have.
I have a JSON response as the follwoing, but my problem is there are some characters that is not related to the JSON response I want. So I have pass that JSON response to a JavaScript variable and look into the JSON string. That is at the bottom.
-----------JSON Response------------
{
"readyState":4,
"responseText":"<?xml version=\"1.0\"encoding=\"utf-8\"?>\r\n<string>{\"kind\":\"analytics#gaData\",\"id\":\"https://www.googleapis.com/analytics/v3/data/ga?ids=ga:76546294&dimensions=ga:userType&metrics=ga:users&start-date=2014-10-01&end-date=2014-10-23&max-results=10\",\"query\":{\"start-date\":\"2014-10-01\",\"end-date\":\"2014-10-23\",\"ids\":\"ga:76546294\",\"dimensions\":\"ga:userType\",\"metrics\":[\"ga:users\"],\"start-index\":1,\"max-results\":10},\"itemsPerPage\":10,\"totalResults\":2,\"selfLink\":\"https://www.googleapis.com/analytics/v3/data/ga?ids=ga:76546294&dimensions=ga:userType&metrics=ga:users&start-date=2014-10-01&end-date=2014-10-23&max-results=10\",\"profileInfo\":{\"profileId\":\"76546294\",\"accountId\":\"289147\",\"webPropertyId\":\"UA-289147-1\",\"internalWebPropertyId\":\"456104\",\"profileName\":\"US - Institutional Investors - NP Microsite\",\"tableId\":\"ga:76546294\"},\"containsSampledData\":false,\"columnHeaders\":[{\"name\":\"ga:userType\",\"columnType\":\"DIMENSION\",\"dataType\":\"STRING\"},{\"name\":\"ga:users\",\"columnType\":\"METRIC\",\"dataType\":\"INTEGER\"}],\"totalsForAllResults\":{\"ga:users\":\"1110\"},\"rows\":[[\"New Visitor\",\"826\"],[\"Returning Visitor\",\"284\"]]}</string>",
"status":200,
"statusText":"OK"
}
-----------End of JSON ------------
I want to remove these characters from the beginning of the string:
`{"readyState":4,"responseText":"<?xml version=\"1.0\"encoding=\"utf-8\"?>\r\n<string>`
And I want to remove these character from the end of the string:
`</string>","status":200,"statusText":"OK"}`
So I want to remove these characters. I think a set of JavaScript String functions to be used. But I don't know how to mix them and use.
Could someone help me to solve this matter?
Thanks and regards,
Chiranthaka
UPDATE
I have used the follwoing AJAX function to send and get the JSON response back.
function setJsonSer() {
formData = {
'Email': 'clientlink#site.com',
'Password': 'password1234',
'URL': getVaria()
};
$.ajax({
url: "/APIWebService.asmx/AnalyticsDataShowWithPost",
type: 'POST',
data: formData,
complete: function(data) {
var jsonResult = JSON.stringify(data);
alert(JSON.stringify(data));
Load(data);
}
});
}
UPDATE 02
function setJsonSer() {
formData = {
'Email': 'clientlink#russell.com',
'Password': 'russell1234',
'URL': getVaria()
};
$.ajax({
url: "/APIWebService.asmx/AnalyticsDataShowWithPost",
type: 'POST',
data: formData,
dataType: 'json',
complete: function(data) {
var jsonResult = JSON.stringify(data);
alert(jsonResult);
Load(data);
}
});
}
I looked at your code:
complete: function(data) {
var jsonResult = JSON.stringify(data);
alert(jsonResult);
Load(data);
}
So you want to stringify your customized result, but your result is not well parsed JSON*? If yes then:
complete: function(data) {
var responseText = data.responseText;
var responseJson = JSON.parse(responseText.match(/[{].*.[}]/));
// you can skip `JSON.parse` if you dont want to leave it as `String` type
alert(JSON.stringify(responseJson)); //or just `responseJson` if you skip `JSON.parse`
Load(JSON.stringify(responseJson));
}
This can solve your problem for a while. But I think the problem is in your backend which did not serve well parsed JSON data. My recommendation is fixing your backend system first.
*Not well parsed JSON because your result some kind of including XML type of string under JSON object.
You have to parse JSON to get stuff which is inside it (You have
done this)
You have to parse the XML to get text which is inside the XML
Here's sample code for XML parsing:
