I'm using Mockjax for the first time to mock a Restful API which will return a series of data given an id. Right now i have a json file that has several Items, and i would like to have a function inside Mockjax (or where necessary) to return only the queried ID. how can I achieve this?
current code :
$.mockjax({
url: "/Api/Cases/{caseId}",
proxy: "/mocks/cases nuevo.json",
dataType: 'json',
responseTime: [500, 800]
});
$.ajax({
type: 'GET',
url: '/Api/Cases/',
data: {caseId: taskId},
success: function(data){
//use the returned
console.log(data);
}
});
current error:
GET http://localhost:8080/Api/Cases/?caseId=100 404 (Not Found)
Great question... yes, you can do this. But you'll have to write the functionality yourself using the response callback function and then making a "real" Ajax request for the file (instead of using the proxy option). Below I just make another $.ajax() call and since I have no mock handler setup for that endpoint, Mockjax lets it go through.
Note that setting up URL params is a little different than you suggest, here is what the mock setup looks like:
$.mockjax({
url: /\/Api\/Cases\/(\d+)/, // notice the regex here to allow for any ID
urlParams: ['caseID'], // This defines the first matching group as "caseID"
responseTime: [500, 800],
response: function(settings, mockDone) {
// hold onto the mock response object
var respObj = this;
// get the mock data file
$.ajax({
url: 'mocks/test-data.json',
success: function(data) {
respObj.status = 200;
// We can now use "caseID" off of the mock settings.urlParams object
respObj.responseText = data[settings.urlParams.caseID];
mockDone();
},
error: function() {
respObj.status = 500;
respObj.responseText = 'Error retrieving mock data';
mockDone();
}
});
}
});
There is one other problem with your code however, your Ajax call does not add the ID to the URL, it adds it to the query string. If you want to use that API endpoint you'll need to change your source code $.ajax() call as well. Here is the new Ajax call:
$.ajax({
type: 'GET',
url: '/Api/Cases/' + taskId, // this will add the ID to the URL
// data: {caseId: taskId}, // this adds the data to the query string
success: function(data){
//use the returned
console.log(data);
}
});
Note that this presumes the mock data is something like:
{
"13": { "name": "Jordan", "level": 21, "id": 13 },
"27": { "name": "Random Guy", "level": 20, "id": 27 }
}
What I have ended up doing, is: I have left the $.mockjax function untouched, and i have manipulated the data inside the ajax request, using jquery's $.grep function as follows:
$.ajax({
type: 'GET',
url: '/Api/Cases/' + taskId,
success: function(data){
//note you have to parse the data as it is received as string
data = JSON.parse(data);
var result = $.grep(data, function(e){ return e.caseId == taskId; });
//since i'm expecting only one result, i pull out the result on the 0 index position
requestedData = result[0];
}
});
The $.grep() method removes items from an array as necessary so that all remaining items pass a provided test see Jquery API, And since our test is that the caseId attribute of the element equals to the taksId variable sent, it will return all the elements that match the given Id, in this case, only one, this is why I've taken only the result on the 0 index position requestedData = result[0];
**Note: **
A more suited solution would be a mixture between what i've done and #jakerella 's answer, since their method implements the find element method inside the mockjacx function, and my function presumes a usual JSON response:
[{"caseId": 30,"name": "Michael"},{"caseId": 31,"name": "Sara"}]

suppose my URL is example.com/controller/method/
when I use this ajax code it makes URL like example.com/controller/method/method which not getting data.
function getProductList() {
var category = document.getElementById('Category').value;
$.ajax({
type: 'POST',
url: 'GetProductList',
data: {CategoryId: category},
dataType: 'json',
cache:false,
success: function (response) {
}
});
}
but when my URL is example.com/controller/method then ajax getting data correctly. but i want to get data from the database on both situations.
Typically there is a one-to-one relationship between a URL string and its corresponding controller class/method. So you can not use example.com/controller/method/method.The segments in a URI normally follow this pattern: example.com/class/function/id/ , So your last method argument treated as a id. so create method in controller with the default argument Ex. public function mymethod($method = ''){ /** Your logic goes here */ }
Can't seem to find what I'm looking for in searches so this might be a duplicate but I haven't found an original yet sooo....
I have a an ajax call:
$.ajax({
url: "/events/instructor/",
type: 'POST',
data: {
instructorID: $(this).attr("id")
},
complete: function (data) {
$("#name").html(data["responseText"]["name"]);
$("#email").html(data["responseText"]["email"]);
$("#photo").html(data["responseText"]["photo"]);
$("#summary").html(data["responseText"]["summary"]);
$("#url").html(data["responseText"]["url"]);
}
});
The data being returned is encoded in JSON by the server (C#).
Obviously, data["responseText"]["fieldName"] isn't doing the trick. I could do splits and whatnot but that would mean that if the format changes, I'd need to make sure that the code above keeps up with the changed shape of the data.
How can I say something as simple as data["responseText']["fieldName"] to get the value out of that key?
i think you need to parse json first. look at the api.jquery.com/jquery.parsejson
// data = '{ "name": "John" }'
var obj = jQuery.parseJSON( data );
console.log( obj.name);
// result will be "John"
P.S. also better use 'succes' instead 'complete', you can read about this here Difference between .success() and .complete()?
success: function(data) {
console.log("response is good", data);
},
error: function (){
console.log("something is went wrong");
}
try using like this:
complete: function (data) {
var data=JSON.parse(data);
$("#name").html(data.responseText.name);
$("#email").html(data.responseText.email);
$("#photo").html(data.responseText.photo);
$("#summary").html(data.responseText.summary);
$("#url").html(data.responseText.url);
}
to get only correct response use success.
i've this piece of code that performs an AJAX call
$.ajax({
url : 'inviaCommento.php',
type : 'POST',
data : {page: page, category: category}
dataType : 'json',
success : function (msg)
//...and so on
The problem is that i want to check if a search parameter is set, if yes i've to add the word to the data parameters.
The question is: can i costruct the data parameters before the call appendig values to it?
Something like this:
if $('#searchBtn').val()!=''
{
data.append(search: $('#searchBtn').val())
}
Yeah, just create an array.
var data = {something: [], page: page, category: category, somekey: "default"};
data.something.push("a");
data.something.push("b");
if (...) {
data.somekey = "new value";
}
$.ajax({
...
data: data
});
Yup, but data isn't a list, it's an object, so you just assign to the appropriate key.
var data = {page:page}; // ... current value of data: param in the $.ajax call
if($('#searchBtn').val()!=='')
{
data.search= $('#searchBtn').val();
}
You'd put this above the $.ajax() call.
I want to get data from server and suggest with typeahead.
I get my data from list to an usl like /foo/q=QUERY and this query return json like ["salam","bye", "khodafez,].
How i can use from bootstrap typeahead to suggestion.
I try this code:
<script type="text/javascript">
$(document).ready(function() {
$("#vahid").typeahead({
// ???
});
});
</script>
According to the documentation, you just provide a function for source in the options:
$("#vahid").typeahead({
source: function(query, process) {
// `query` is the text in the field
// `process` is a function to call back with the array
$.ajax({
// Your URL
url: "/foo",
// Your argument with the query as its value
data: {q: query},
// Success callback -- since it expects the first
// parameter to be the data, and that's what the
// success callback is called with, you can just
// use `process` directly
success: process
});
}
});
The above assumes that the response correctly identifies the response as Content-Type: application/json. If it doesn't, add
dataType: "json"
...to your ajax options.
I'm using the asynchronous mechanism because you're querying a server. If you already had the data client-side, you could simply return it from the source function directly. But they (intelligently) don't require you to retrieve it synchronously from the server, as that would lead to a bad XU.
Accourding to docs https://github.com/tcrosen/twitter-bootstrap-typeahead
you can add ajax attr like :
$('#myElement').typeahead({
ajax: '/path/to/mySource'
});
or
var mySource = [
{ id: 1, name: 'Terry'}, { id: 2, name: 'Mark'}, { id: 3, name: 'Jacob'}
];
$('#myElement').typeahead({
source: mySource
});
for local data
I'm just starting to use javascript and json.
I need to read data (getInformation function) from a json file when processing an event in a javascript function. So I need it to be synchronic. I don't know if I am missing something in the code, or if I have to create an Request and handle the callback, or if I need to import additional javascript to use json. Because I don't know how to make it work. It doesn't work because at the end the array is empty. Any help is aprreciated.
The json file:
{"Users": [
{"Name": "Jane",
"Points": 67,
"age": 23},
{
"Name": "Sam",
"Points": 65,
"age": 21}
]}
Option 1 - Function called by another function which is processing an event:
var getInformation = function()
{
var path = "./data/users.json";
var informationArray= [];
console.log("Loading ....");
$.getJSON(path, function(data)
{
$.each(data, function(key, val)
{
informationArray.push(key + '-' + val);
});
});
return informationArray;
}
Option 2 - Function called by another function which is processing an event:
var getInformation = function() {
var path = "./data/users.json";
var informationArray= [];
$.ajax({
url: path,
async: false,
dataType: 'json',
success: function(response) {
$.each(response.items,
function(item) {
informationArray.push(item);
});
informationArray.push("success");
}
});
return informationArray; }
I have seen the following thread and tried what is there but doens't work for me. I would like to know where is the problem in my code or if require any special configuration.
Thread: Is there a version of $getJSON that doesn't use a call back?
When JavaScript is running in a browser it needs to make an AJAX request to the server to access a JSON file. It is possible to write the AJAX request by hand but that is complex and difficult to make work in all browsers. Instead most people use a library like jQuery. You will need to include jQuery in your web page with something like:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>
Then in any script tag lower in the html page you should be able to do something like:
$.ajax({
url: "data/users.json",
dataType: "json",
success: function(response) {
$.each(response.Users, function(item) {
informationArray.push(item);
});
informationArray.push("success");
}
});
see http://api.jquery.com/jQuery.ajax/
To load a JSON file (and not require a callback) you'd use:
var url = 'http://yoursite.com/data/users.json';
var j = [];
$.ajax({
type: 'GET',
url: url,
dataType: 'json',
success: function(data) { j = data;},
async: false
});
alert(j.Users[0].Name);
