I was wondering if it is possible to pass an array to a php function using the jQuery AJAX function. I have the following as my javascript
arr_data = {
field01: "data 01",
field02: "data 02",
field03: "data 03",
field04: "data 04"
}
$.ajax({
url: "scripts/php/phpfunc.php",
type: "GET",
dataType: "json",
data: {
'action': "exec_find",
'field01': arr_data["field01"],
'field02': arr_data["field02"],
'field03': arr_data["field03"],
'field04': arr_data["field04"]
},
success: function(result) {
// continue program
},
error: function(log) {
// handle error
}
});
When I try to do the following though
arr_data = {
field01: "data 01",
field02: "data 02",
field03: "data 03",
field04: "data 04"
}
$.ajax({
url: "scripts/php/phpfunc.php",
type: "GET",
dataType: "json",
data: {
'action': "exec_find",
'data': arr_data
},
success: function(result) {
// continue program
},
error: function(log) {
// handle error
}
});
I receive it in the PHP as "Array". How can I correctly send the object so that it is usable by the PHP function?
Please try to pass the array in the format of json. Then use the get the json in your php and access the json array.
<script>
arr_data = {
field01: "data 01",
field02: "data 02",
field03: "data 03",
field04: "data 04"
}
var myJsonString= JSON.stringify(arr_data);
$.ajax({
url: "scripts/php/phpfunc.php",
type: "GET",
dataType: "json",
data: {
'action': "exec_find",
'data': myJsonString
},
success: function(result) {
// continue program
},
error: function(log) {
// handle error
}
});
</script>
this is your java script. and below is the php
$dataJson=json_decode($_GET['data']);
here you can get the json array and loop through it and do what ever you want.
Please have try at this. This is working in my case.
from the second ajax you can access the data based on the property names like: $_GET['data']['field01']
$_GET['data'] is the js object converted in php in a associative array
try this :
$.ajax({
url: "scripts/php/phpfunc.php",
method: "POST",
dataType: "json",
data: {
'action': "exec_find",
'data': arr_data.serialize()
},
serialize()
http://api.jquery.com/serialize/
convert your array in string

Not getting array of data from ajax to controller.
$.ajax({
type: "POST",
url: "/Home/List",
traditional: true,
contentType: 'application/json',
data: {
"Query": JSON.stringify(Query) //change this
success: function() {}
});,
And array of Query :
0: {label: "abc:", value: "123", type: "Select"} 1: {label: "xyz",
value: "Hum", type: "text"}
Can anyone help ?
Try something like this
<script type="text/javascript">
var query=[{label: "abc:", value: "123", type: "Select"},{label: "abc:", value: "1232", type: "Select"} ];
$.ajax({ type: "POST",
url: "/Home/List",
traditional: true,
contentType: 'application/json',
data: JSON.stringify(query),
success: function (){
} });
</script>
I think something along this may work for you.
function sendarray() {
var arr = [];
var json = {
"label": 'abc',
"value": 1234,
"Name": 'Name'
};
arr.push(json);
json = {
"label": 'abc2',
"value": 1234,
"Name": 'Name2'
};
arr.push(json);
var myarray = JSON.stringify(arr);
$.ajax({
url: '/controller/GetArray',
type: 'POST',
data: { array: myarray },
success: function (data) {
//Do something
},
error: function () {
//Do something
}
});
}
then in the controller
public JsonResult GetArray(string array)
{
var obj = JsonConvert.DeserializeObject<object>(array);
return Json("");
}
This will send an string with all the data in the array to the controller, then you turn string with json format into an object list
I am firing an ajaxcall on page load and getting an array back. Now for each element called groupId present in the array, I have to fire another ajaxcall to get the group name and group notes.
Now I need to create a final array that would have the array returned from the first ajaxcall and merged with the corresponding group name and info returned from the second call.
This is the array returned from the first ajaxcall:
[{
"customMessage": "THis is the first message",
"groupIdx": 13
}, {
"customMessage": "This is the second message",
"groupIdx": 14
}]
Which I am getting by doing:
$.ajax({
type: "GET",
url: '<html:rewrite page="/rest/pre-visit-instruction/list"/>',
dataType: "json"
}).done(function(data) {
vueInst.preVisitInstructions = data;
});
Now to this I am appending a .each function and calling another ajaxcall.
This is the final code:
$.ajax({
type: "GET",
url: '<html:rewrite page="/rest/pre-visit-instruction/list"/>',
dataType: "json"
}).done(function(data) {
vueInst.preVisitInstructions = data;
}).each(dataObj, function(j, data) {
$.ajax({
type: "GET",
url: '<html:rewrite page="/rest/group/"/>' + data.groupIdx + '/info',
dataType: "json"
}).
My question is: How do I get the data returned from the .each function and append it to the original object?
$.each() function must be inside of .done() function.
Update: According to the last comment:
You should use Array#filter.
data.data = response2.filter(function(x) {
return x.groupId === data.groupIdx;
});
Something like this:
$(function() {
var vueInst = {
preVisitInstructions: []
};
var result = [];
$.ajax({
type: "GET",
url: "https://gist.githubusercontent.com/dannyjhonston/17455e3ef90fb3cf096d1f051d4331e5/raw/ad51c85e7722a83e7085ad63e26a524b769efe50/firstData.json",
dataType: "json"
}).done(function(response1) {
$.each(response1, function(j, data) {
$.ajax({
type: "GET",
url: "https://gist.githubusercontent.com/dannyjhonston/e610dd23f830b108bc1e24c78f66b3b6/raw/54851535eedd1e94a1a944ddf3d63412e83349f8/secondData.json",
dataType: "json"
}).done(function(response2) {
data.data = response2.filter(function(x) {
return x.groupId === data.groupIdx;
});
result.push(data);
});
vueInst.preVisitInstructions = result;
});
});
$("#btnCheck").on("click", function() {
console.log(JSON.stringify(vueInst.preVisitInstructions));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button id="btnCheck">Check data</button>
The result should be:
[{
"customMessage": "THis is the first message",
"groupIdx": 13,
"data": [
]
},
{
"customMessage": "This is the second message",
"groupIdx": 14,
"data": [{
"groupId": 14,
"groupName": "Test 1",
"groupNotes": "THis is a note"
},
{
"groupId": 14,
"groupName": "Test 2",
"groupNotes": "THis is a note"
},
{
"groupId": 14,
"groupName": "Test 3",
"groupNotes": "THis is a note"
}
]
}
]
I'm trying to display the json that i get and parse it in the success function of ajax.
What I have so far:
Ajax:
data = "Title=" + $("#Title").val() + "&geography=" + $("#geography").val();
alert(data);
url= "/portal/getResults.php";
$.ajax({
url: url,
type: "POST",
//pass the data
data: data,
dataType: 'json',
cache: false,
//success
success: function(data) {
alert(data);
}
});
getResults.php (JSON output):
{
"results": [
{
"DocId": 2204,
"Title": "Lorem ipsum dolor sit amet, consectetur",
"Locations": [
{
"State": "New York",
"City": ""
},
{
"State": "New York",
"City": "New York City"
}
],
"Topics": [
3,
7,
11
],
"PublicationYear": "2011",
"Organization": "New Yorks Times",
"WebLocation": "www.google.com",
"Description": "Lorem Ipsum"
}
],
"TotalMatches": 1
}
I expect the result in data to be the the json from getResults.php but instead I get [object Object].
I have also tried the code below but get no response:
success: function(data) {
var json1 = JSON.parse(data);
alert(json1);
}
since you're telling jQuery that you want dataType:'json', the ajax function parses the JSON response into an object for you. the result object you see should be an object with data matching the JSON response from your server. if you need the string version, try JSON.stringify(), otherwise you can just use the object as is: data['results'][0]['DocId'], etc
good luck!
Here is an example for your request : http://jsfiddle.net/5y5ea98n/
var echo = function(dataPass) {
$.ajax({
type: "POST",
url: "/echo/json/",
data: dataPass,
cache: false,
success: function(json) {
alert(JSON.stringify(json));
}
});
};
$('.list').live('click', function() {
$.get("http://www.json-generator.com/api/json/get/bQxORzxQGG?indent=2", function(data) {
var json = {
json: JSON.stringify(data),
delay: 1
};
echo(json);
});
});
I tried some code relate to this and it worked successfully.
function ajaxToParseJson(){
AUI().use('aui-io-request', function(A){
A.io.request('${jsonAjaxURL}', {
dataType:'json',
method: 'post',
data: {
execute: 'JsonLogic',
numberVal:'Pass Json String Here if needed from Screen'
},
on: {
success: function()
{
var empName = this.get('responseData').name;
var id = this.get('responseData').id;
console.log("Name: "+empName);
console.log("Id: "+id);
/** Since return type of this function is bydefault Json it will return Json still if you want to check string below is the way**/
var data = JSON.stringify(this.get('responseData'));
alert(data);
}
}
});
});
}
I have an Employee Class with two fields id,name.
I'm making an API call with this code:
$.ajax({
type: "GET",
url: "https://example/example.json",
beforeSend: function(xhr) {
xhr.setRequestHeader("apikey", "user")
},
success: function(data){
alert(data.folder.item);
}
})
That returns nothing, except for an error in the console saying:
"Uncaught TypeError: Cannot read property 'item' of undefined"
The JSON data looks like this when I use the url in the browser:
{
"folder": {
"item": 123123,
"item 2": false,
"item 3": "content",
"item 4": [
{
"subitem": "content"
},
{
"subitem": "content2"
}
]
}
}
I was expecting "123123" in the alertbox, but nope. So what am I doing wrong?
If its a JSON string you are getting it will need to be parsed. Try this:
$.ajax({
type: "GET",
url: "https://example/example.json",
beforeSend: function(xhr) {
xhr.setRequestHeader("apikey", "user")
},
success: function(data){
var parsed = JSON.parse(data);
alert(parsed.folder.item);
}
});
Or to force jquery to parse it for you:
$.ajax({
type: "GET",
url: "https://example/example.json",
dataType: 'json',
beforeSend: function(xhr) {
xhr.setRequestHeader("apikey", "user")
},
success: function(data){
alert(data.folder.item);
}
});
I have the following json object:
cNGJSON = {
"one": graph1.graphNode, "two": graph2.graphNode, "three": graph3.graphNode, "four": graph4.graphNode, "five": graph5.graphNode,"six": graph6.graphNode,
"seven": graph7.graphNode,"eight": graph8.graphNode, "nine": graph9.graphNode,"ten": graph10.graphNode, "eleven": graph11.graphNode, "twelve": graph12.graphNode,
"thirteen": graph13.graphNode,"fourteen": graph14.graphNode,"fifteen": graph15.graphNode,"sixteen": graph16.graphNode, "seventeen": graph17.graphNode, "eighteen": graph18.graphNode,
"nineteen": graph19.graphNode
};
where graph1.graphNode is an integer array.
[1,2,3,4]
I send this to the server with jQuery:
$.ajax({
url: 'validate',
type: 'post',
dataType: 'json',
success: function (data) {
console.log("Success!!");
},
data: cNGJSON
});
However I get a
Expected BEGIN_OBJECT but was STRING at line 1 column 1
Error every time I try.
I tried with setting the cNGJSON to:
cNGJSON = {
"one": "Number one", "two": "Number two"
};
Still I get the same error.
As you want to send JSON object in your XHR request you need to stringify the JSON object first
$.ajax({
url: 'validate',
type: 'post',
dataType: 'json',
success: function (data) {
console.log("Success!!");
},
data: JSON.stringify(cNGJSON)
});
