I have a function that sends values to the db, the function works great until I include the success function with a location.reload(). Then it sends empty values.. sometimes though... sometimes it works fine, but I should be able to rely on it.
Any suggestions?
$.ajax({
url: 'core/manage_articles.php',
type: 'POST',
data: {
blog:title,
title:title,
text:text,
lat:lat,
lng:lng,
success: function() {
location.reload();
}
}
});
Well... you didn't say what lib you are using so I'll just go on a semiwild guess (might not be right):
$.ajax({
url: 'core/manage_articles.php',
type: 'POST',
data: {
blog:title,
title:title,
text:text,
lat:lat,
lng:lng
},
success: function() {
location.reload();
}
}
});
Try it like this.

On Chrome its working properly but on firefox its not working
function myfoo(){
// Write your logic here
$.ajax({
type: "POST",
url: "update.php",
dataType: 'json',
data: {Eventid: 'Eventid',Seats:'Seats'},
success: function (r) {}
});
}
When unloading window
$(window).on('beforeunload', function () {
return 'Are you sure you want to leave?';
});
when unloading call function
$(window).on('unload', function () {
console.log('calling ajax');
myfoo();
});
Both "onbeforeunload" and "unload" is working but in your scenario you are expecting to send ajax call. so try changing ajax asynchronous to false.
function myfoo(){
// Write your logic here
$.ajax({
type: "POST",
url: "update.php",
dataType: 'json',
async: false,
data: {Eventid: 'Eventid',Seats:'Seats'},
success: function (r) {}
});
}
I have an AJAX request which gets data from the database and then populates the page with the data collected. The problem I am having is that currently the ajax request is in a setInterval which is being called every second.
setInterval(function () {
$.ajax({
method: "POST",
url: "/PLM/FetchPageContent",
dataType: "json",
success: function (data) {
console.log(data);
}
});
}, 1000);
This is fetching the data every second which is a huge strain on the server as it's making a request and then I am calling it again even when the data hasn't come through first time.
Is there a way that I can call the same AJAX request over and over but only after it's finished fetching the data first time and not keep going up?
There are better architectures to accomplish this type of scenario (websockets as mentioned in the comments would be one example), but to do strictly what you're asking, sure! Wrap it in a function that calls itself:
function getData(){
$.ajax({
method: "POST",
url: "/PLM/FetchPageContent",
dataType: "json",
success: function (data) {
console.log(data);
getData();
}
});
}
Replace the setInterval with a setTimeout only once you're done:
function fetchAjax() {
$.ajax({
method: "POST",
url: "/PLM/FetchPageContent",
dataType: "json",
success: function (data) {
console.log(data);
setTimeout(fetchAjax, 1000);
}
});
};
Add a variable to distunguish if ajax call is already underway. If it is, don't do anything. If not, go ahead.
var isAjaxInProgress = false;
setInterval(function () {
if (!isAjaxInProgress){
isAjaxInProgress = true;
$.ajax({
method: "POST",
url: "/PLM/FetchPageContent",
dataType: "json",
success: function (data) {
console.log(data);
isAjaxInProgress = false;
}
});
}
}, 1000);
I am trying to send an ajax call with json array
the call function is
if(objHasValue) {
alert(JSON.stringify(objArray));
alert("before ajax call");
$.ajax({
type: 'POST',
url: 'http://www.web2222.net/Test/test.php',
dataType: 'json',
data: { json: JSON.stringify(objArray) },
success: function(data) {
alert('did it-'+data);
return false;
},
error: function(data){
alert('failure'+data.json);
}
});
}
return false;
somehow it doesn't work
Do I have any mistake there?
Thanks
i am not sure if this is the problem but try something like :
data: { "json": JSON.stringify(objArray) }
I'm trying to do a jquery GET and i want to send a parameter.
here's my function:
$(function() {
var availableProductNames;
$.get("manageproducts.do?option=1", function(data){
availableProductNames = data.split(",");;
alert(availableProductNames);
$("#nameInput").autocomplete({
source: availableProductNames
});
});
});
This doesn't seem to work; i get a null in my servlet when i use request.getParameter("option");
If i type the link into the browser http://www.myite.com/manageproducts.do?option=1 it works perfectly.
I also tried:
$.get(
"manageproducts.do?",
{option: "1"},
function(data){}
which doesn't work either.
Can you please help me?
EDIT:
also tried
$.ajax({
type: "GET",
url: "manageproducts.do",
data: "option=1",
success: function(msg){
availableProductNames = msg.split(",");
alert(availableProductNames);
$("#nameInput").autocomplete({
source: availableProductNames
});
}
});
Still getting the same result.
If you say that it works with accessing directly manageproducts.do?option=1 in the browser then it should work with:
$.get('manageproducts.do', { option: '1' }, function(data) {
...
});
as it would send the same GET request.
Try this:
$.ajax({
type: 'get',
url: 'manageproducts.do',
data: 'option=1',
success: function(data) {
availableProductNames = data.split(",");
alert(availableProductNames);
}
});
Also You have a few errors in your sample code, not sure if that was causing the error or it was just a typo upon entering the question.
I got this working : -
$.get('api.php', 'client=mikescafe', function(data) {
...
});
It sends via get the string ?client=mikescafe
then collect this variable in api.php, and use it in your mysql statement.
This is what worked for me:
$.get({
method: 'GET',
url: 'api.php',
headers: {
'Content-Type': 'application/json',
},
// query parameters go under "data" as an Object
data: {
client: 'mikescafe'
}
});
will make a REST/AJAX call - > GET http://localhost:3000/api.php?client=mikescafe
Good Luck.
aspx site:
<script type="text/javascript">
function AjaxTest() {
var codeVal = "hello world";
if (codeVal) {
$.ajax({
type: "POST",
url: "CheckAge",
data: { code: codeVal },
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function (result) {
alert("in ajax success");
},
error: function () {
alert("error");
}
});
}
}
Its double checked that the javascript function is called.
Controller:
[HttpPost]
public JsonResult CheckAge(String code)
{
return Json("abc");
}
It ended up always in the ajax - error - function.
The Controller function isnt called anyway. Why?
Why get I always an error?
What is wrong?
Check your url that you are posting to. It seems that you are missing the controller part. E.g. it should read /{controller}/{action}.
If that script is directly in the view (i.e. not in an external javascript file) you could have something like:
$.ajax({
type: "POST",
url: <%= Url.Action("CheckAge", "ControllerName") %>,
data: { code: codeVal },
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
cache: false,
success: function (result) {
alert("in ajax success");
},
error: function () {
alert("error");
}
});
Also, I find it advantageous to use firebug to debug ajax stuff. You can set break points in your javascript and also see all the requests and responses.
HTHs,
Charles
EDIT: Try simplifying things... e.g.
$.post('<%= Url.Action("CheckAge", "ControllerName") %>',
{ code: codeVal },
function (data) {
alert("in ajax success");
},
"json");
