Alright, I have multiple buttons which call the same javascript function with a different ID.
Here's my function
function concur(id) {
//alert(id);
//throw ajax request
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "ajax_getter.php?requestid=1&r=" + id,
dataType: "html", //expect html to be returned
success: function (response) {
$("#container").html(response);
//alert(response);
}
}); //ajax end
}
What would I do if I have to make the id as container name?
I mean, would this $("#id").html(response); work for all the dynamic changing ids within the function?
This didn't work for me. What would be the best solution ?
Use string concatenation to use a variable in the jQuery selector.
$("#" + id).html(response);

$(".content-short").click(function() {
$(".content-full").empty();
var contentid=$(this).parent().find(".content-full").attr('data-id');
var content=$(this).parent().find(".content-full");
alert(contentid);
var collegename = $(this).attr('data-id');
$.ajax({
type: "post",
url: "contenthome.php",
data: 'collegename=' + collegename,
dataType: "text",
success: function(response) {
$content.html(response);
}
});
});
here the alert displays the specific data-id but
content=$(this).parent().find(".content-full");
this didn't displays data in content-full div with that specific data-id
anything wrong in the code or something else?
the query displays data if i use(."content-full"); instead of
$(this).parent().find(".content-full");
Inside the ajax callback you are using $content, but you declare your variable as content. May that be the problem?
Your question is not clear. What are you trying to achieve?
$(".content-short").click(function() {
var ID = $(this).attr('data-id');
$('.loadingmessage').show();
$.ajax({
type: "post",
url: "collegeselect.php",
data: 'ID=' + ID,
dataType: "text",
success: function(response){
$(".content-full").html(response);
$('.loadingmessage').hide();
}
});
});
//collegeselect.php// is for loading data from database, //.loadingmessage// is for gif
when i am using this for the first time it displays gif,but the gif is not displayed after the 1st click as the data retrieved is already available in content-full from previous ajax request,
how to display it on every click on content short class?
That happens because you are replacing the actual content with loading GIF image with your response.
So, when you click first time it displayed and after the ajax call sucess as per the code you have replaced the content of .content-full and there is no GIF available then.
Solution : To resolve either send the same image tag with response or Move the loader image out side the .content-full.
Add beforeSend : function() before success in your request.
try
$(".content-short").live(function() {
var ID = $(this).attr('data-id');
$('.loadingmessage').show();
$.ajax({
type: "post",
url: "collegeselect.php",
data: 'ID=' + ID,
dataType: "text",
beforeSend : function()
{
$('.loadingmessage').show();
},
success: function(response){
$(".content-full").html(response);
$('.loadingmessage').hide();
}
});
});
From the comments, I gather that the img is within the .content-full container. The problem is that the img is removed when ajax succeeds since you're doing $(".content-full").html(). One way to fix it is to move the img out of the container. Another way is to store a reference to the img and add it back along with the response via .append() or .prepend() as below.
$(".content-short").click(function() {
var ID = $(this).attr('data-id');
$('.loadingmessage').show();
$.ajax({
type: "post",
url: "collegeselect.php",
data: 'ID=' + ID,
dataType: "text",
success: function(response) {
var $content = $(".content-full");
var $loaderImg = $content.find('.loadingmessage').hide();
$content.html(response).prepend($loaderImg);
}
});
});
Here is a demo mimicking the behaviour thru setTimeout.
Why won't my function work after ajax has succeed?
I have a custom function named filter(), defined in the header as javascript file.
Then i have a series of jquery code to dynamically retrieve data from the server to populate the select box. I would like to call the filter() after the AJAX request has completed since the filter() will manage populated the select box's option.
$.ajax({
url: "checkersc2.php", //This is the page where you will handle your SQL insert
type: "GET",
data: values, //The data your sending to some-page.php
success: function (response) {
$('#loading-image').css('display', 'none');
$dropdownCondition.html(response);
filter();
},
error: function () {
console.log("AJAX request was a failure");
}
});
EDIT: my filter() code is a little long, # http://jsfiddle.net/tongky20/re5unf7p/11/
It looks like you have an invalid selector for dropdownCondition. It probably fails on that line and never calls filter. Unless you defined that variable else where try updating it to a valid element selector and see if it calls filter. Something like:
$('#dropdownCondition').html(response);
Assuming the element id is dropdownCondition.
Full function:
$.ajax({
url: "checkersc2.php", //This is the page where you will handle your SQL insert
type: "GET",
data: values, //The data your sending to some-page.php
success: function (response) {
$('#loading-image').css('display', 'none');
$('#dropdownCondition').html(response);
filter();
},
error: function () {
console.log("AJAX request was a failure");
}
});
I have a page that displays a dynamic amount of "orders" and I have a button to "view" and another button to "print". To display the specific OrderNumber I'm using a javascript function triggered by onmouseover and a jQuery ajax function to change the button text, make a database entry, and then view or print another page. The problem is the order is viewed or printed MULTIPLE times from onmouseover. How can use only jQuery and call the specfic OrderNumber? Here is the code I'm using now:
This code is repeated for each order:
<div class="console_orders_details">
<input type="button" value="View"
id="vieworder'.$row[orderid].'" onmouseover="vieworder('.$row[orderid].');">
</div>
Here is the function to view the order:
function vieworder(id){
$(function(){
$('#vieworder' + id).click(function(){
var orderid = id;
var dataString = 'orderid='+ orderid; //string passed to url
$.ajax
({
url: "includes/ajax/console-view.php", //url of php script
dataType: 'html', //json is return type from php script
data: dataString, //dataString is the string passed to the url
success: function(result)
{
window.open("print.php?view=1&orderid="+id+"");
$('#vieworder' + orderid + ':input[type="button"]').attr("value", "Viewed!").fadeIn(400);
}
});
})
});
}
I'm assuming I need to eliminate the "vieworder" function and use a pure jQuery function. However, I don't know how to send over the order "id", which is why I used javascript.
You can target all elements with an ID that starts with vieworder, and then store the row ID as a data attribute :
<div class="console_orders_details">
<input type="button" value="View" id="vieworder'.$row[orderid].'" data-id="'.$row[orderid].'">
</div>
JS
$(function(){
$('[id^="vieworder"]').on('click', function(){
var orderid = $(this).data('id'),
btn = $('input[type="button"]', this);
$.ajax({
url: "includes/ajax/console-view.php",
dataType: 'html',
data: {orderid : orderid}
}).done(function(result) {
window.open("print.php?view=1&orderid="+orderid+"");
btn.val("Viewed!").fadeIn(400);
});
});
});
Your onmouseover event is probably being fired many times, resulting in your problem. This might help to stop unwanted extra calls, by ignoring them unless the previous one has completed.
var activeRequests = {}; // global
function vieworder(id){
if (activeRequests[id]) { return; }
activeRequests[id] = true;
$(function(){
$('#vieworder' + id).click(function(){
var orderid = id;
var dataString = 'orderid='+ orderid; //string passed to url
$.ajax
({
url: "includes/ajax/console-view.php", //url of php script
dataType: 'html', //json is return type from php script
data: dataString, //dataString is the string passed to the url
success: function(result) {
delete activeRequests[id];
window.open("print.php?view=1&orderid="+id+"");
$('#vieworder' + orderid + ':input[type="button"]').attr("value", "Viewed!").fadeIn(400);
}
});
})
});
}
First, don't have a dynamic id that you have to parse, and don't have an event handler in your html:
<div class="console_orders_details">
<input type="button" value="View" class="vieworder" data-id="$row[orderid]">
</div>
Next, create an event handler for just what you want to do. .one() will set an event handler to fire only once:
$(document).ready(function (){
$(".console_orders_details").one("mouseover", ".vieworder" function(){
var dataString = "orderid=" + $(this).data("id");
$.ajax({
url: "includes/ajax/console-view.php", //url of php script
dataType: 'html', //json is return type from php script
data: dataString, //dataString is the string passed to the url
success: function(result) {
window.open("print.php?view=1&" + dataString);
$(this).val("Viewed!");
}
});
});
});
If you want this to work onclick, then just change the mouseover to click. Also, fadeIn doesn't work on values. Here is a fiddle that has the basics: http://jsfiddle.net/iGanja/EnK2M/1/
i.e.
$("#savenew").live('click', function(e) {
var user=<?php echo $user?>;
$.ajax({
type: "POST",
url: "actions/sub.php",
data:{user: user} ,
success: function(){
$('#savenew').html('<span>Unsubscribe</span>');
$(this).attr('id', 'clean'); // this my problem my problem
}
});
});
the id after the ajax request, is not changing from savenew to clean, but the html is perfectly fine, so i know the ajax request is working. what do u thiunk the problem is?
You just need to save the context (via the context option for $.ajax()) so this still refers to #savenew, like this:
$("#savenew").live('click', function(e) {
var user=<?php echo $user?>;
$.ajax({
context: this, //add this!
type: "POST",
url: "actions/sub.php",
data:{user: user} ,
success: function(){
$(this).attr('id', 'clean').html('<span>Unsubscribe</span>');
}
});
});
Also note that this allows you to chain and clean things up a bit.
$(this) inside success: function(){ does not refer to $('#savenew').
As you do in the line above, you need to reference it by id:
$('#savenew').attr('id', 'clean');
