The following JQuery Request works fine in IE but not in FF and Chrome.
I am running the following page from its file location e.g. file:///C:/Test/json.htm and requesting a page running on localhost.
What is the reason for this?
And how can I get it to work for FF and Chrome?
<body>
<input type="button" value="Search" id="search-button" />
<script language="javascript" type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(function() {
$('#search-button').click(function() {
var parms = {
id: 27
};
$.ajax({
type: 'POST',
url: 'http://localhost:51621/Test/GetJSONMessage/',
async: false,
data: parms,
dataType: 'json',
success: function(data, testStatus) {
alert(data.message);
}
});
});
});
</script>
</body>
Where GetJSONMessage is supplied by an ASP.Net MVC JSonResult :
[HttpPost]
public JsonResult GetJSONMessage(int id)
{
return Json(new { message = ("hello world " + id.ToString()) });
}
Because you're hosting from the filesystem, and making a request to localhost, Chrome and FF will see this as a cross domain request, and therefore a security issue.
If you type the URL directly into the location bar, you'll probably get your response.
Safari is a little more easy going about those "security issues" when you're hosting from the filesystem.

What else change is required at JAVA side to get the birthday information?
I am using jquery-ui autocomplete to retrieve items from a SQL database which is working fine but I would like to move the autocomplete list to another part of the page.
I have been trying to use the Position option from here but cant seem to get the correct syntax when applying to my code?
<script src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.8.0.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.23/jquery-ui.js"></script>
<script type="text/javascript">
$(function () {
$("#txtCity").autocomplete({
source: function (request, response) {
var param = { cityName: $('#txtCity').val() };
$.ajax({
url: "test.aspx/GetCities",
data: JSON.stringify(param),
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {
response($.map(data.d, function (item) {
return {
value: item
}
}))
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
select: function (event, ui) {
event.preventDefault();
minLength: 2//minLength as 2, it means when ever user enter 2 character in TextBox the AutoComplete method will fire and get its source data.
}
});
});
</script>
I wanted to move the autocomplete box to the right hand side of the textbox.
After a nights sleep my first attempt again this morning worked fine, think I had originally only missed a comma in one of my attempts yesterday.
I just stripped it back to a basic implementation using an array instead of the ajax call and then applied the working syntax to my code.
Wasted FAR too much time on this yesterday, just shows taking a step back and time away from the screen helps work things out!
Thanks for your help

I can use ajax call on *.cshtml file as below.It's working properly.
$.ajax({
url: '#Url.Action("GetAllBooks", "Book")',
cache: false,
type: 'GET',
contentType: 'application/json; charset=utf-8',
data: {},
success: function (data) {
self.Books(data); //Put the response in ObservableArray
}
});
But How can I call same method on seperate *.js file ?When I used above code it's not working?
CSHTML (I prefer the tag input):
#* without the attribute 'name' *#
<input type="hidden" value="#Url.Action("GetAllBooks", "Book")" id="UrlBookGetAllBooks" />
#* or *#
<div style="display:none;" data-url="#Url.Action("GetAllBooks", "Book")" id="UrlBookGetAllBooks"></div>
JS:
var url = $('#UrlBookGetAllBooks').val();
//or for tag div
var url = $('#UrlBookGetAllBooks').data('url');
$.ajax({
url: url,
cache: false,
type: 'GET',
contentType: 'application/json; charset=utf-8',
data: {},
success: function (data) {
self.Books(data); //Put the response in ObservableArray
}
});
HTML - Contains data- attributes
<div id="ExampleDiv"
data-url = "#Url.Action("Action", "Controller", new { area = "AreaName" })">
</div>
HTML - Option 2
<div id="ExampleDiv"
url-Val = "#Url.Action("Action", "Controller", new { area = "AreaName" })">
</div>
JQuery - Contains data- attributes
var Url_Value = $('#ExampleDiv').data('url');
JQuery - Option 2
var Url_Value = $('#ExampleDiv').attr('url-Val');
Ajax Call
$.ajax({
url: Url_Value,
cache: false,
type: 'GET',
contentType: 'application/json; charset=utf-8',
data: {},
success: function (data) {
self.Books(data); //Put the response in ObservableArray
}
});
For such solution, I recommends you to create a JavascriptController with a "JavascriptActionResult" or a new "JavascriptActionResult" on the BookController along with the view that outputs the desired javascript. That way you can write Javascript dynamically with razor and also have garantee that the Route Pattern behavior of your MVC will be followed. With all that set, the page would be:
<script type="text/javascript" src="#Url.Action("GetAllBooksJS","Book")"></script>
PS: There is not a native JavascriptActionResult in MVC, but you could extend the ActionResult to perform that or simple force a Content-Type in the classic ActionResult function.
Bellow is a working case that Ive made in MVC3.
Controller:
public class BookController : Controller
{
//
// GET: /Book/
public ActionResult Index()
{
return View();
}
public JsonResult GetAllBooks() {
return Json(new[] { new { name = "Book1" }, new { name = "Book2" } });
}
public ActionResult GetAllBooksJS()
{
Response.ContentType = "text/javascript";
return View();
}
}
Index View:
#{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
<script type="text/javascript" src="#Url.Content("~/scripts/jquery-1.7.1.min.js")"> </script>
<script type="text/javascript" src="#Url.Action("GetAllBooksJS","Book")"></script>
</head>
<body>
<div>
<button>Get books ajax</button>
</div>
</body>
</html>
GetAllBooksJS View:
#{
Layout = null;
}
$(document).ready(function(){
$('button').on('click',function() {
GetBooksAjax();
});
});
function GetBooksAjax() {
$.ajax({
url: '#Url.Action("GetAllBooks","Book")',
type: 'POST',
dataType: 'json',
success: function(oJSON) {
$.each(oJSON,function(){
alert(this.name);
})
}
})
}
GetAllBooksJS View v2, In this second version the Javascript, as soon as it is loaded by the Index view, will engage the Ajax Call, I guess thats your case:
#{
Layout = null;
}
function GetBooksAjax() {
$.ajax({
url: '#Url.Action("GetAllBooks","Book")',
type: 'POST',
dataType: 'json',
success: function(oJSON) {
$.each(oJSON,function(){
alert(this.name);
})
}
})
}
GetBooksAjax();
I know this question might be repeated but my query is different let me explain, I have a drop down in page and by selecting value in drop down list,and I click on submit button.. I want by click on submit button I need to load partial view in tag that is list of records of selected drop down list value.
i tried this :
$("#btnclick").click(function () {
$.ajax({
type: 'POST',
url: '#Url.Content("~/Search/MDLNoDataList")',
data: mdlno,
success: function (data) { $("#viewlist").innerHtml = data; }
});
});
but not getting result And I m using these many jquery plugins
<script src="../../Scripts/jquery-migrate-1.0.0.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.unobtrusive-ajax.js" type="text/javascript"></script>
<script src="../../Scripts/jquery-1.5.1.min.js" type="text/javascript"></script>
If i understand correctly, below is what you need to do.
HTML Example:
<div id="records">
</div>
<select id="ddlRecordType">
<option value="1">Type 1</option>
<option value="2">Type 2</option>
</select>
<input type="submit" value="Load Records" id="btn-submit" />
jQuery Code
$(document).ready(function(){
$('#btn-submit').click(function(){
var selectedRecVal=$('#ddlRecordType').val();
$('#records').load('/LoadRecords?Id='+selectedRecVal);
return false; // to prevent default form submit
});
});
Here ?Id= is the query string parameter passed to server to get
the selected item in dropdown.
Edit: The below answer was added, as the question content changed from initial post
$("#btnclick").click(function () {
$.ajax({
type: 'POST',
url: '#Url.Action("MDLNoDataList","Search")',
data: mdlno,
success: function (data) {
// $("#viewlist")[0].innerHtml = data;
//or
$("#viewlist").html(data);
}
});
return false; //prevent default action(submit) for a button
});
Make sure you cancel the default action of form submission by returning false from your click handler:
$("#btnclick").click(function () {
$.ajax({
type: 'POST',
url: '#Url.Action("MDLNoDataList", "Search")',
data: mdlno,
success: function (data) {
$("#viewlist").html(data);
}
});
return false; // <!-- This is the important part
});
And if you are using the WebForms view engine and not Razor make sure you use the correct syntax to specify the url:
$("#btnclick").click(function () {
$.ajax({
type: 'POST',
url: '<%= Url.Action("MDLNoDataList", "Search") %>',
data: mdlno,
success: function (data) {
$("#viewlist").html(data);
}
});
return false; // <!-- This is the important part
});
If you do not return false, the form is simply submitted to the server when you click on the submit button, the browser redirects away from the page and obviously your AJAX call never has time to execute.
You will also notice some improvements I made to your original code:
Using the Url.Action helper when pointing to a server side controller action in order to take into account routes defined in your application.
Using jQuery's .html() method instead of innerHTML to set the contents of a given element.
You need AJAX for this purpose.
$.get(url, data, function(data) { $(element).append(data) });
and Partial View that is vague.
element {
overflow:hidden;
}
In a single asp.net MVC page, I've to show 3 reports of same layout/structor. So I created a page that generated a report using Knockout databind and 10 reports are generated by passing some additional parameters.
I tried to load all 3 reports using Ajax partial view and by this way I'm populating those 10 reports in one single page.
Now I happen to see a strange issue, the last report data appears for all the 3 reports though the data for each report is different. Anyone knows how to handle this issue ?
Main Page View, where I call 3 reports via Ajax call.
<div id="RecentlyAddedReport" ></div>
<div id="RecentlyConsultedReport"></div>
<div id="RecentlyPrescribedReport"></div>
<!-- start here -->
<script type="text/javascript">
$(document).ready(function () {
AjaxLoadReport('RecentlyAddedReport', 'Patient/Report?type=RecentlyAdded&name=Recently Added');
AjaxLoadReport('RecentlyConsultedReport', 'Patient/Report?type=RecentlyConsulted&name=Recently Consulted');
AjaxLoadReport('RecentlyPrescribedReport', 'Patient/Report?type=RecentlyPrescribed&name=Recently Prescribed');
});
function AjaxLoadReport(reportType, actionURL) {
var resultDiv = $('#' + reportType);
$.ajax({ type: "GET", url: actionURL, data: {},
success: function (response) {
resultDiv.html('');
resultDiv.html(response);
}
});
}
</script>
Report View - I call this same view for all the 3 reports
