Is possible to get partial results and write to a div from a $.ajax post?
My js code
$('#submit').livequery('click', function(event) {
event.preventDefault();
$('#loading').show();
var myvar= $("#myvar").val();
$.ajax({
type: "POST",
url: "process.php",
cache: false,
data: ({'myvar':myvar}),
success: function(data){
$('#loading').hide();
$('#main_content').html(data);
},
});
return false;
});
The code from process.php
function send($string = "") {
echo $string;
echo str_pad('', 4096)."\n";
#ob_flush();
#flush();
}
for($i=1;$i<=10;$i++){
send($i);
sleep(5);
}
Is possible to show on #main_content the result like this:
show 1 -> wait -> show 2 -> wait .....
Right now i get all result after the process is made: 12345678910
PHP code is run on the server and, as such, cannot affect the client-side browser behavior like you are asking. The way to accomplish what you want is to pass all the information from PHP to your browser and handle the logic in jQuery or javascript. Send all of your information and store it in some variables/arrays and after your POST, split up the info and display it to the browser with a timeout callback like this:
setTimeout(function() {
// Do something after 5 seconds
}, 5000);

title says it all, the way the script currently works is if its successful, it brings back a message back from my php code, i want it to also refresh the page after 3 seconds
$(function(){
$('button[type=submit]').click(function(e){
e.preventDefault();
$.ajax({
type: "POST",
url: "postadvert.php",
data: $("#myform").serialize(),
beforeSend: function(){
$('#result').html('<div class="success"><img src="../../images/loading-blue.gif" width="25" /></div>');
},
success: function(data){
$('#result').html(data),
$('#result2').html('<meta http-equiv="refresh" content="3">'); // i added that doesn't working
}
});
});
});
A couple of things. First, you need a semicolon after your first line in the success function. Next, you can use the setTimeout function in javascript where you pass a function and a time to wait in milliseconds. Lastly, you can call the location.reload() to refresh the page.
success: function(data){
$('#result').html(data);
setTimeout(function(){location.reload();},3000);
}
Include the following in your success callback:
window.setTimeout(function() {
document.location.href = document.location.href;
}, 3000);
Assigning to document.location.href automagically causes the browser to load the URL so assigned; assigning its own value back to it therefore causes a refresh. The window.setTimeout() call tells the browser to wait three seconds, then run the function given as its first argument.
I have the following ajax code that takes in 3 variables and passes them to a php file, and this is all fine and dandy. I want to do a redirect using the value stored in one of these variables. I figured I could just do window.location.href = within the success in the ajax call, but for some reason, it doesn't seem to respond to the click, and simply does nothing.
Here is the ajax function, hope y'all can help!
$("#findItem").click(function() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position){
$.ajax({
type: 'get',
url: 'http://plato.cs.virginia.edu/~aam3xd/cabbage/closestBuildingWeb.php',
data: {
foodItemId: $('#foodItem').val(),
sentLongitude: position.coords.longitude,
sentLatitude: position.coords.latitude
},
success: function(data){
//$('#answer').html(data);
//the following line doesn't seem to be executing....
window.location.href = foodItemId+"/"+sentLatitude+"/"+sentLongitude;
}
});
});
I think you should use your url into that window.location
window.location.href = "www.example.com/"+foodItemId+"/"+sentLatitude+"/"+sentLongitude;
i have an ajax load request working in wordpress, but i would like to load the content from another page into the container div. at the moment it just passes the url in $dataToSend as a string?
jQuery(document).ready(function(){
var $dataToSend = "my-page.php";
var $testBtn = jQuery('#text-ajax-btn');
var $holdingCtn = jQuery('#my-holding-ctn');
$testBtn.click(function(){
jQuery.ajax({
type:'POST',
url: myAjax.ajaxurl,
data:{
action:'myAjax',
dataToSend:$dataToSend,
},
success: function(data,textStatus,XMLHttpRequest){
$holdingCtn.html("");
$holdingCtn.append(data);
},
error: function(XMLHttpRequest, textStatus, errorThrown){
alert(errorThrown);
}
});
});
});
how can i pass an entire .php page through as the $dataTosend?
I do this all the time for wordpress, give me a sec to access my repository and I will show you example code.
I think problem is your my-page.php! I imagine you custom coded it. So it doesn't have necessary functions loaded.
put following code at the top of your my-page.php (this will help with 500 error you are getting)
require('../../../wp-load.php');
ajax part should look something like this:
//start ajax
$.ajax({
url: "http://localhost/wp-content/themes/theme/my-page.php",
type: "POST",
data: data,
cache: false,
success: function (data) {
console.dir(data);
}
})
If you want to load content from my-page.php file then you can load from the server side using
$data = file_get_contents('path/to/file/my-page.php'); // pass right path/url
Then, just echo the content from your function (registered ajax handler in WordPress using add_action) and in this case it should be
echo $data;
die(); // terminate the further execution
So, it should look something like
add_action( 'wp_ajax_myAjax', 'yourAjaxHandler' );
add_action( 'wp_ajax_nopriv_myAjax', 'yourAjaxHandler' );
function yourAjaxHandler(){
$data = file_get_contents('path/to/file/my-page.php');
die($data); // echo out the string and terminates execution
}
In your success callback, you can use
success: function(data){
jQuery('#my-holding-ctn').html(data);
}
Not sure if this is fully applicable, but the super easy way is just
$("#myDiv").load("myFile.php?foo=1&bar=2...");
I'm using Symfony2.1 with Doctrine2.1
I'd like to use AJAX for many features on my site , editing a title , rate an article , create an entity on the fly , etc.
My question is simple :
Do I need to create a JQuery function for each functionnality , like this :
$('#specific-functionality').bind('click', function(e){
var element = $(this);
e.preventDefault();
// the call
$.ajax({
url: element.attr('href'),
cache: false,
dataType: 'json',
success: function(data){
// some custom stuff : remove a loader , show some value, change some css
}
});
});
It sounds very heavy to me, so I was wondering if there's any framework on JS side, or a specific method I can use to avoid this. I was thinking about regrouping items by type of response (html_content , boolean, integer) but maybe something already exists to handle it nicely !
From what I understand, you are asking for lighter version of JQuery ajax method. There are direct get/post methods instead of using ajax.
$.get(element.attr('href'), {'id': '123'},
function(data) {
alert(data);
}
);
To configure error function
$.get(element.attr('href'), {'id': '123'}, function(data) {alert(data);})
.error(function (XMLHttpRequest, textStatus, errorThrown) {
var msg = jQuery.parseJSON(XMLHttpRequest.responseText);
alert(msg.Message);
});
Also, you can pass callback function to do any synchronous operations like
function LoadData(cb)
{
$.get(element.attr('href'), { 'test': test }, cb);
}
And call
LoadData(function(data) {
alert(data);
otherstatements;
});
For progress bar, you use JQuery ajaxStart and ajaxStop functions instead of manually hiding and showing it. Note, it gets fired for every JQuery AJAX operation on the page.
$('#progress')
.ajaxStart(function () {
//disable the submit button
$(this).show();
})
.ajaxStop(function () {
//enable the button
$(this).hide();
});
Instead of $('#specific-functionality').bind('click', function(e){, try this:
$(".ajax").click(function(){
var url = $(this).attr("href") ;
var target = $(this).attr("data-target") ;
if (target=="undefined"){
alert("You forgot the target");
return false ;
}
$.ajax(....
And in html
<a class="ajax" href="..." data-target="#some_id">click here </a>
I think it is the simplest solution. If you want some link to work via ajax, just give it class "ajax" and put data-target to where it should output results. All custom stuff could be placed in these data-something properties.
Hey. I need some help with jQuery Ajax calls. In javascript I have to generste ajax calls to the controller, which retrieves a value from the model. I am then checking the value that is returned and making further ajax calls if necessary, say if the value reaches a particular threshold I can stop the ajax calls.
This requires ajax calls that need to be processes one after the other. I tried using async:false, but it freezes up the browser and any jQuery changes i make at the frontend are not reflected. Is there any way around this??
Thanks in advance.
You should make the next ajax call after the first one has finished like this for example:
function getResult(value) {
$.ajax({
url: 'server/url',
data: { value: value },
success: function(data) {
getResult(data.newValue);
}
});
}
I used array of steps and callback function to continue executing where async started. Works perfect for me.
var tasks = [];
for(i=0;i<20;i++){
tasks.push(i); //can be replaced with list of steps, url and so on
}
var current = 0;
function doAjax(callback) {
//check to make sure there are more requests to make
if (current < tasks.length -1 ) {
var uploadURL ="http://localhost/someSequentialToDo";
//and
var myData = tasks[current];
current++;
//make the AJAX request with the given data
$.ajax({
type: 'GET',
url : uploadURL,
data: {index: current},
dataType : 'json',
success : function (serverResponse) {
doAjax(callback);
}
});
}
else
{
callback();
console.log("this is end");
}
}
function sth(){
var datum = Date();
doAjax( function(){
console.log(datum); //displays time when ajax started
console.log(Date()); //when ajax finished
});
}
console.log("start");
sth();
In the success callback function, just make another $.ajax request if necessary. (Setting async: false causes the browser to run the request as the same thread as everything else; that's why it freezes up.)
Use a callback function, there are two: success and error.
From the jQuery ajax page:
$.ajax({
url: "test.html",
context: document.body,
success: function(){
// Do processing, call function for next ajax
}
});
A (very) simplified example:
function doAjax() {
// get url and parameters
var myurl = /* somethingsomething */;
$.ajax({
url: myurl,
context: document.body,
success: function(data){
if(data < threshold) {
doAjax();
}
}
});
}
Try using $.when() (available since 1.5) you can have a single callback that triggers once all calls are made, its cleaner and much more elegant. It ends up looking something like this:
$.when($.ajax("/page1.php"), $.ajax("/page2.php")).done(function(a1, a2){
// a1 and a2 are arguments resolved for the page1 and page2 ajax requests, respectively
var jqXHR = a1[2]; /* arguments are [ "success", statusText, jqXHR ] */
alert( jqXHR.responseText )
});
