I've searched the entire Internet, all of it, and cannot find an answer to this.
I'm using the ColdFusion CFWheels Framework to query a database. The query is done via AJAX like this:
var id = $("#ship-id").val();
$.ajax({
type: "POST",
url: "/my-controller/my-method?format=json",
data: {shipId: id},
dataType: "json",
success: function(response) {
var resultHtml = '';
$.each(response, function(i, value) {
resultHtml += '<tr><td>' + value.FIRSTNAME + ' ' + value.LASTNAME + '</td></tr>';
});
$("#my-table").html(resultHtml);
}
});
I need to paginate that result set. In CFWheels you normally do that by setting the handle, page, perPage and order values in the query like this:
var order = model("order").findAll(
select="id, firstname, lastname, email",
where="orderid IN (#ValueList(orders.id)#)",
handle="ordersQuery",
page=params.page,
perPage=5,
order="lastname"
);
Then you just put this line in your view:
<cfoutput>#paginationLinks(handle="ordersQuery")#</cfoutput>
But... how in the heck can you get pagination to work with an AJAX call?
I think that something along these lines might be your answer (notice I removed the url and added those params to data ...
$.ajax({
type: "POST",
data: {
shipId: id,
controller: myController,
action: myAction,
page: params.page,
},
dataType: "json",
success: function(response) {
var resultHtml = '';
$.each(response, function(i, value) {
resultHtml += '<tr><td>' + value.FIRSTNAME + ' ' + value.LASTNAME + '</td></tr>';
});
$("#my-table").html(resultHtml);
}
});

AJAX method
Now , I want the count variable to bind with html and need help as i don't have enough knowledge of AJAX
$.ajaxSetup({
beforeSend: function (xhr) {
var token = localStorage.getItem('ngStorage-premier_agent_token')
var value = 'Bearer ' + JSON.parse(token)
xhr.setRequestHeader('Authorization', value);
}
});
$.ajax({
url: "/api/activity/listcount",
type: "GET",
success: function (data) {
console.log(JSON.stringify(data))
var count=data.count;
}
});
added a container where you want to print your HTML, like a div
<div></div>
and then append the result to that div on your success function
$.ajax({
url: "/api/activity/listcount",
type: "GET",
success: function (data) {
console.log(JSON.stringify(data))
$("div").append("result is" + data.count);
}
});
I am getting a syntax error for the square bracket '[' from my JSON file. Given below is the JSON.
[
{
"Product Name":"CPE 10281",
"Application":"Tyres",
"Weight":150,
"Cost to Produce":5000,
"Grade":"A",
"Cost to Sell":40000,
"Strength":100
},
{
"Product Name":"CPE 10282",
"Application":"computers",
"Weight":250,
"Cost to Produce":4000,
"Grade":"H",
"Cost to Sell":25000,
"Strength":90
}
]
I am trying to use AJAX to read my JSON file.
$.ajax({
url: "dataProductJSON.json",
dataType: 'json',
mimeType: "application/json",
success: function (data) {
var item = [];
$.each(data, function (key, val) {
item.push('<li id="' + key + '">' + val + '</li>');
});
$('<ul/>', {
'class': 'interest-list',
html: item.join('')
}).appendTo('body');
},
});
I am running my html from Eclipse with Apache Geronimo as the server.
Please Help.
You are missing a { in the below line
success: function (data)
Make it
success: function (data) {
Edit
You are having parsing the data incorrectly , do it as below
$.ajax({
url: "test.html",
dataType: 'json',
mimeType: "application/json",
success: function (data) {
var item = [];
$.each(data, function (key, val){
$.each(val, function (innerKey, innerValue){
item.push('<li id="' + innerKey + '">' + innerValue + '</li>');
});
});
$('<ul/>', {
'class': 'interest-list',
html: item.join('')
}).appendTo('body');
},
});
You need to use 2 loop , one for the array and the other to loop through the object property
I tried things and it is working fine
I have an ajax call to a function in my controller. I need to pass a parameter to that function but it is not happening. My ajax call:
$("#BTN_Plus").click(function () {
var CurrentPage = #Model.CurrentPage;
$.ajax({
type: "POST",
url: "/Accueil/ListerIncidentsHotline",
data: JSON.stringify(CurrentPage),
contentType: 'application/json; charset=utf-8',
success: function (data) {
$("#Affichage").html(data);
}
});
});
The function in my controller:
public PartialViewResult ListerIncidentsHotline( int page = 1)
{
int NextPage = 1 + page;
const int PageSize = 10;
int NumDossier = StructureData.DonneNumDossier((string)Session["Utilisateur"], (string)Session["MotDePasse"]);
IEnumerable<IncidentHotline> ListeIncidents = StructureData.DonneIncidentsHotline(NumDossier);
int NbreIncidents = StructureData.DonneNombreIncidents(NumDossier);
ViewBag.NombreIncidents = NbreIncidents;
var viewModel = new IncidentsPageInfo()
{
NumPages = (int)Math.Ceiling((double)ListeIncidents.Count() / PageSize),
CurrentPage = NextPage,
PageSize = PageSize,
Incidents = ListeIncidents.Skip((NextPage - 1) * PageSize).Take(PageSize),
};
return this.PartialView(viewModel);
}
When I make an alert of the variable CurrentPage, it shows me the right value, but when it comes to the ajax call, i get an error saying that the parameter is null. Can't figure out what's wrong with that.
well as a data you need to pass a numerable value with the name of page, change your ajax data
$.ajax({
type: "POST",
url: "/Accueil/ListerIncidentsHotline",
data: JSON.stringify(CurrentPage),
contentType: 'application/json; charset=utf-8',
success: function (data) {
$("#Affichage").html(data);
}
});
change data to data: {page: CurrentPage}
This is much easier....
$.get("/Accueil/ListerIncidentsHotline", { CurrentPage: #Model.CurrentPage } ).
done(function (data) {
$("#Affichage").html(data);
});
Obviously the problem came out of my ajax call. So I have to concatenate the name of the parameter with its value inside the method JSON.Stringify, as below:
$("#BTN_Plus").click(function () {
var CurrentPage = #Model.CurrentPage;
alert(CurrentPage);
$.ajax({
type: "POST",
url: "/Accueil/ListerIncidentsHotline",
data: JSON.stringify({ page: CurrentPage }),
contentType: 'application/json; charset=utf-8',
success: function (data) {
$("#Affichage").html(data);
}
});
});
I have simple question to display data on html page. Following code displays array of json data on screen. but, I want to display it by each element such as "url", "img_url" and so on.
could you please let me know who to do it ?
ajax code
var dataString = 'url=' + pathname + '&img_name=' + img_name + "&tag=" + tag;
$.ajax({
type: "POST",
url: "image_finder.php",
data: dataString,
dataType: 'json',
complete: function (xhr, status) {
if (status === 'error' || !xhr.responseText) {
//handleError();
alert("error");
} else {
var data = xhr.responseText;
$('#tt').html("<div id='message'></div>");
$('#message').html(data);
}
}
});
json return
{"cid":"14","url":"http:\/\/localhost\/","img_url":"http:\/\/static.naver.net\/www\/up\/2013\/0305\/mat_173330634c.jpg","img_name":"mat_173317134c.jpg","html":"<div id=\"hotspot-19\" class=\"hs-wrap hs-loading\">\r\n<img src=\"http:\/\/static.naver.net\/www\/up\/2013\/0305\/mat_173330634c.jpg\">\r\n<div class=\"hs-spot-object\" data-type=\"spot\" data-x=\"95\" data-y=\"64\" data-width=\"30\" data-height=\"30\" data-popup-position=\"left\" data-visible=\"visible\" data-tooltip-width=\"200\" data-tooltip-auto-width=\"true\">\r\nasdf\r\n<\/div>\r\n<div class=\"hs-spot-object\" data-type=\"spot\" data-x=\"168\" data-y=\"53\" data-width=\"30\" data-height=\"30\" data-popup-position=\"left\" data-visible=\"visible\" data-tooltip-width=\"200\" data-tooltip-auto-width=\"true\">\r\nrere\r\n<\/div>\r\n<\/div>\r\n","jscript":""}
$.ajax({
type: "POST",
url: "image_finder.php",
data: dataString,
dataType: 'json',
success: function (data) {
for(var item in data){
console.info(item);//print key
console.info(data[item]);//print value
}
}
});
I hope this is what you need.
I have this code:
for(var i in dataJson){
direcc=dataJson[i].dir ;
id=dataJson[i].id ;
$.ajax({
url: 'http://dev.virtualearth.net/REST/v1/Locations?query=' + direcc + '&key=mykey&jsonp=?',
dataType: 'json',
async: false,
success: function(result) {
loc = result.resourceSets[0].resources[0].point.coordinates;
direcc=result.resourceSets[0].resources[0].address.formattedAddress;
lat=loc[0];
long=loc[1];
$("#bing").append('latitudeBing:' + lat + '<p>longitudeBing:' + long+'$$$$$$'+id);
}
});
The problem is that I want to write latitude+longitude+ id, but when it writes the id is the last for all of them ( id goes from 1-200, and in all coordinates appears 200).
The original function was $getjson and i changed it to make the $ajax call async:false, but that doesn't fix my problem.
Could anybody help me please? Thank you very much!!
Edited with the correct answer now.
Fiddle to show the concept
for(var i in dataJson){
var direcc = dataJson[i].dir;
var id = dataJson[i].id;
makeAjaxCall(direcc, id);
}
function makeAjaxCall(direcc, id) {
$.ajax({
url: 'http://dev.virtualearth.net/REST/v1/Locations?query=' + direcc + '&key=mykey&jsonp=?',
dataType: 'json',
async: false,
success: function(result) {
loc = result.resourceSets[0].resources[0].point.coordinates;
direcc=result.resourceSets[0].resources[0].address.formattedAddress;
lat=loc[0];
long=loc[1];
$("#bing").append('latitudeBing:' + lat + '<p>longitudeBing:' + long+'$$$$$$'+id);
}
});
}
This puts the "current" direcc and id in the scope of the makeAjaxCall function. The Fiddle I added is just showing how.
Also, no need to keep the async: false, around, so feel free to remove that if you want.
