$('#lev_nr').on('input', {
source: function(request, response) {
$.ajax({
url : 'pallavvikelse/jsonData',
dataType: "json",
data: {
name_startsWith: request.term,
type: 'lev_table',
row_num : 1
},
success: function(data) {
response($.map(data, function(item) {
var code = item.split("|");
return {
label: code[0],
value: code[0],
data : item
}
}));
}
});
},
autoFocus: true,
minLength: 1,
select: function(event, ui) {
var names = ui.item.data.split("|");
$('#lev_namn').val(names[1]);
var txt = $('#avta').val(names[2]);
if (txt.val() == "ja"){
$('#t').hide();
}
} }).trigger('input');
Can someone see why this does not work?
I am trying to change autocomplete function to on.input but I can't get it to work.
The code works perfectly when i change the first line to $('#leverantors_nr').autocomplete({
and when I remove .trigger('input')
$('#lev_nr').on('input', function() {
$.ajax({
url: 'pallavvikelse/jsonData',
data: {
name_startsWith: this.value,
type: 'country_table',
row_num: 1
},
dataType: 'json',
success: function(data) {
alert(data);
var names = data.split('|');
alert(names[0]);
}
});
});
I have managed to make it work this far, but when i try to alert(names[0]) i get nothing when alert(data) i get resault.. The data i get loocks like this: 5000950|TEST|BLABLA
Wen i try to split and alert again it dosent work
$('#leverantors_nr').on('input', function() {
$.ajax({
url: 'pallavvikelse/jsonData',
data: {
name_startsWith: this.value,
type: 'country_table',
row_num: 1
},
dataType: 'json',
success: function(data) {
alert(data.lev_namn);
}
});
});
Problem solved:
i changed the database so it outputs array like this:
$arr['lev_nr'] = $row->lev_nr;
$arr['lev_namn'] = $row->lev_namn;
I think you are not properly parsing JSON data.

I want to send the data via ajax to other page. I have isolated the problem. This is the code.
Thank you all for your help..But no effect..
updated code
It worked...
<script>
$(document).ready(function(){
$(".edit").click(function(event) {
event.preventDefault(); //<--- to prevent the default behaviour
var box = 1233;
var size=123;
var itemname=123;
var potency=123;
var quantity=12333;
var dataString ={
'box' :box,
'size':size ,
'itemname':itemname,
'potency':potency,
'quantity':quantity
};
$.ajax({
url: "dd.php",
type: "post",
data: dataString,
success: function(data) {
alert(data);
},
error: function(data) {
alert(data);
}
});
});
});
</script>
So I click the link,it navigates, to dd.php which has
<?php
echo json_encode(array('itemcode'=>$_POST['itemname']));
echo $_POST['itemname'];
?>
I get Object Object as alert. What am doing wrong? Pls throw some light here..thanks you..
$(document).ready(function(){
$(".edit").click(function(event) {
event.preventDefault();
var data = {"box":1233,
"size":565,
"itemname":565,
"potency":876,
"quantity":234};
$.ajax({
url: "dd.php",
type: "post",
data: data,
dataType: "json",
success: function(data) {
if(console){
console.log(data);
}
},
error: function(data) {
if(console){
console.log(data);
}
}
});
});
});
few things to consider... you can post data as object..which is clean and easier to use
$(".edit").click(function(event) {
event.preventDefault(); //<--- to prevent the default behaviour
var box = 1233;
....
var dataString ={'box':box,'size':size,'itemname':itemname,'potency':potency,'quantity':quantity};
$.ajax({
url: "dd.php",
type: "post",
data: dataString,
dataType: "json", //<--- here this means the response is expected as JSON from the server
success: function(data) {
alert(data.itemcode); //<--here alert itemcode
},
error: function(data) {
alert(data);
}
});
so you need to send the response as json in PHP
<?php
echo json_encode(array('itemcode'=>$_POST['itemname']))
?>
Here you are using querystring as sent in GET request.
If you want to send the data in same form, you can use this with GET request type:
$.ajax({
url: "dd.php"+dataString,
type: "get",
dataType: "json",
success: function(data) {
console.log(data);
alert(data.itemcode);
},
error: function(data) {
alert(data);
}
});
Or for POST request,you will have to put data in json object form, So you can use :
var dataString ={
'box' :box,
'size':size ,
'itemname':itemname,
'potency':potency,
'quantity':quantity
};
$.ajax({
url: "dd.php",
type: "post",
data: dataString,
dataType: "json",
success: function(data) {
console.log(data);
alert(data.itemcode);
},
error: function(data) {
alert(data);
}
});
});
And put echo in your php code :
<?php
echo json_encode(array('itemcode'=>$_POST['itemname']))
?>
Javascript alert shows [Object object] for object. You can see response using console.log or can use that key with alert.
For more information, refer jQuery.ajax()
I send an array from PHP with json_encode, and I trying to get with AJAX and jQuery.
Every thing is ok.
JSON structure is :
names{"p1":"John","p5":"Smith"}
jQuery code is :
$.ajax({
type: "POST",
url: "return.php",
dataType: "json",
data: "id=56",
success: function(data) {
$(data.names).each(function(key, txt) {
alert(txt);
});
}
}
this code don't return any thing! I think browser don't enter in each
what should I do ?
instead this:
$(data.names).each(function(key, txt) {
alert(txt);
});
use this:
$.each(data.names, function(key, txt) {
alert(txt);
});
and your json seems to be incorrect as you mentioned: names{"p1":"John","p5":"Smith"}
this should be like this:
{
"names": {
"p1": "John",
"p5": "Smith"
}
}
you can check your json here: http://jsonlint.com/
I'd suggest you use jQuery's $.getJSON(); http://api.jquery.com/jQuery.getJSON/
But to answer your question directly; you didn't close your ajax() function.
$.ajax({
type: "POST",
url: "return.php",
dataType: "json",
data: "id=56",
success: function(data) {
$(data.names).each(function(key, txt) {
alert(txt);
});
}
});
In your code you could just use parseJSON().
$.ajax({
type: "POST",
url: "return.php",
dataType: "json",
data: "id=56",
success: function(data) {
var d = jQuery.parseJSON(data);
// ... do stuff
}
});
I have the following code.
The ajax query works, and the data returned from the server is a valid json.
I succeeded to make the autocomplete dropdown work with a remote data source, through a request like this : http://jqueryui.com/demos/autocomplete/#remote.
My problem is that the data returned from the jquery.ajax doesn't show in the autocomplete. Anyone can help? thks.
jQuery( "#input_2_5" ).autocomplete({
source: function(request, response){
jQuery.ajax({
url: "url/wp-admin/admin-ajax.php",
type:'POST',
dataType: 'json',
data:{
action: 'word_autocomplete'
},
success: function(data) {
return data;
}
});
}
});
jQuery( "#input_2_5" ).autocomplete({
source: function(request, response){
jQuery.ajax({
url: "url/wp-admin/admin-ajax.php",
type:'POST',
dataType: 'json',
data:{
action: 'word_autocomplete'
},
success: function (data) {
if (data.d != null) {
response($.map(data.d, function (item) {
return {
value: item.name
}
}));
}
}
});
}
});
This formulation worked for me: Mine was a jsonp request, but this should do it:
jQuery( "#input_2_5" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "url/wp-admin/admin-ajax.php",
type: 'POST',
data: 'searchterm=' + request.term,
success: function( data ) {
response( $.map( data, function ( item ) {
return item;
}));
}
});
Obviously your server side should be looking for 'searchterm' in the query string...
I have a php program where I just test some sample data. I am getting error as missing ] after element list. How can I read this?
$dataDetailsList = array();
array_push($dataDetailsList, array('a' =>'1','b' =>'2','c' =>'3','d' =>'4','e' =>'5'));
echo json_encode(array("DataDetailsList"=>$dataDetailsList));
Then in my jQuery processor I am doing like this.
function requestData() {
$.ajax({
url: 'live-server-data.php',
success: function(data) {
//alert(json);
var jsonData = eval(" (" + data + ") ");
},
cache: false
});
function requestData() {
$.ajax({
url: 'live-server-data.php',
success: function(data) {
//alert(json);
var jsonData = data;
},
cache: false,
dataType: 'json' //data type that it will return
});
}
Don't use eval is evil.
Instead of this use:
JSON.parse(data); // not supported in IE7 and below
I think you need to try
dataType: 'json'
That is,
$.ajax({
url: 'live-server-data.php',
dataType: 'json',
success: function(data) {
var jsonData = data;
console.log(jsonData);
$.each(jsonData.DataDetailsList, function(key, val) {
var key = Object.keys(val)[0],
value = val[key];
console.log(key); // output: a, b, c ...
console.log(value); // output: 1, 2, 3,...
// alternative
for(var key in val) {
console.log(key);
console.log(val[key]);
}
});
},
cache: false
})
You should just set the dataType to json and jQuery will do the trick for you..
$.ajax({
url: 'live-server-data.php',
dataType: 'json', //Added dataType json
success: function(data) {
//Now data is a javascript object (JSON)
},
cache: false
});
I am trying to implement a simple autocomplete script using jQuery UI and CodeIgniter 2 but my model keeps telling me there is an undefined variable so I dont know if my setup is right.
My view
$(function() {
$("#txtUserSuburb").autocomplete({
source: function(request, response){
$.ajax({
url: "autocomplete/suggestions",
data: {
term: $("#txtUserSuburb").val()
},
dataType: "json",
type: "POST",
success: function(data){
response(data);
}
});
},
minLength: 2
});
});
My controller
function suggestions(){
$this->load->model('autocomplete_model');
$term = $this->input->post('term', TRUE);
$rows = $this->autocomplete_model->getAutocomplete($term);
echo json_encode($rows);
}
My Model
function getAutocomplete() {
$this->db->like('postcode', $term, 'after');
$query = $this->db->get('tbl_postcode');
$keywords = array();
foreach($query->result() as $row){
array_push($keywords, $row->postcode);
}
return $keywords;
}
There arent any errors except it doesn't seem to be passing the $term variable to the model.
Yeah, I think you need getAutocomplete() to have a param "$term":
function getAutocomplete($term) {
change post value in Ajax
$(function() {
$("#txtUserSuburb").autocomplete({
source: function(request, response){
$.ajax({
url: "autocomplete/suggestions",
data: {
term: request.term //change post value
},
dataType: "json",
type: "POST",
success: function(data){
response(data);
}
});
},
minLength: 2
});
});
set page header as JSON in a controller
function suggestions(){
$this->load->model('autocomplete_model');
$term = $this->input->post('term', TRUE);
$rows = $this->autocomplete_model->getAutocomplete($term);
$this->output
->set_content_type('application/json')
->set_output(json_encode($rows));
}
