I am new to javascript
My Javascript code is not working on the data that is fetched from the other page searchworld.php
When I see the pagesource the fetched data is not appearing
<script type="text/javascript" >
$(function() {
$(".search").keyup(function() {
var searchbox = $(this).val();
var dataString = 'searchword='+ searchbox;
if(searchbox=='')
{
}
else
{
$.ajax({
type: "POST",
url: "worldsearch.php",
data: dataString,
cache: false,
success: function(html){
$("#display").html(html).show();
}
});
}
return false;
});
});
</script>
$(".search").on("keyup", function() {
.on() causes your events to bind on newly added content loaded with AJAX

I am a decent PHP programer and recently I got stuck in a javascript code.
I have the code below:
$(function () {
$('.more').live("click", function () {
var ID = $(this).attr("id");
if (ID) {
$("#more" + ID).html('<img src="moreajax.gif" />');
$.ajax({
type: "POST",
url: "scripts/loadmore.php",
data: "lastmsg=" + ID,
cache: false,
success: function (html) {
$("div#updates").append(html);
$("#more" + ID).remove();
}
});
} else {
$(".morebox").html('The End');
}
return false;
});
});
This code submit without problems one PHP variable to the process page loadmore.php using this input
<div id="more<?= $load_id ?>" class="morebox" style="margin-bottom: 200px;">
<a href="#" class="more" id="<?php echo $load_id; ?>">
load more
</a>
</div>
How can put more variables in the input and the javascript code to work with them on the process page?
I want to set one or two more variables.
UPDATE:
I updated the code like this:
HTML input:
<div id="more<?= $load_id ?>" class="morebox" style="margin-bottom: 200px;">
load more</div>
JAVASCRIPT CODE:
<script type="text/javascript">
$(function() {
$('.more').live("click",function()
{
var ID = $(this).attr("data-id");
var ACT = $(this).attr("data-act");
if(ID)
{
$("#more"+ID).html('<img src="moreajax.gif" />');
$.ajax({
type: "POST",
url: "scripts/loadmore.php",
data: {"lastmsg="+ ID, "act="+ ACT},
cache: false,
success: function(html){
$("div#updates").append(html);
$("#more"+ID).remove();
}
});
}
else{
$(".morebox").html('The End');
}
return false;
});
});
</script>
I am not sure if the data lines was writed properly because the script looks like it's frozen now
SOLVED:
I just used a datastring like this
<script type="text/javascript">
$(function() {
$('.more').live("click",function()
{
var ID = $(this).attr("data-id");
var ACT = $(this).attr("data-act");
var dataString = 'lastmsg='+ ID + '&act=' + ACT;
if(ID)
{
$("#more"+ID).html('<img src="moreajax.gif" />');
$.ajax({
type: "POST",
url: "scripts/loadmore.php",
data: dataString,
//data: {"lastmsg="+ ID, "act="+ ACT },
cache: false,
success: function(html){
$("div#updates").append(html);
$("#more"+ID).remove();
}
});
}
else{
$(".morebox").html('The End');
}
return false;
});
});
</script>
Just send data as an object:
data: {
"lastmsg": "lastmsg="+ ID,
"anotherData": "someData"
}
You'll retrieve them in your PHP script as follows:
$_POST["lastmsg"];
$_POST["anotherData"];
my html:
<span id="loading"><img src="ajax-loader.gif" /> Please Wait</span>
#loading{display:none;}
my js:
var Progressajax = false;
$(function() {
$(".commentmoreview").click(function(){
if(Progressajax) return;
Progressajax = true;
var element = $(this);
var id = element.attr("id");
$('#loading').show();
var value = $('.pagecont'+id).val();
var info = 'id='+id+'&pagecont='+value;
$.ajax({
type: "POST",
url: "php-comments/php/loadmorecomments.php",
data: info,
success: function(data){
$('#loading').hide();
Progressajax = false;
value = parseInt(value)+parseInt(5);
$('.pagecont'+id).val(value);
$(data).hide().prependTo('#loadmorecomments'+id).fadeIn(1000);
//$('#loadmorecomments'+id).prepend(data);
}
});
});
});
what is wrong that loading span is not working?
thank you friends!
The best way to show loader image while making ajax calls is using Ajax Global Events
$(document).bind("ajaxSend", function(){
$("#loading").show();
}).bind("ajaxComplete", function(){
$("#loading").hide();
});
can you change
$('#loading').show();
to
$('#loading').attr("display","block");
and try to use it like this
$.ajax({
type: "POST",
url: "php-comments/php/loadmorecomments.php",
data: info,
beforeSend: function(){
$('#loading').attr("display","block");
},
success: function(data){
$('#loading').attr("display","none");
Progressajax = false;
value = parseInt(value)+parseInt(5);
$('.pagecont'+id).val(value);
$(data).hide().prependTo('#loadmorecomments'+id).fadeIn(1000);
//$('#loadmorecomments'+id).prepend(data);
}
});
I have a vote function in one of my projects. Please see following code.
$(function () {
$(".vote").click(function () {
var id = $(this).data("id");
var name = $(this).data("name");
var dataString = 'id=' + id;
//var dataId = id;
var parent = $(this);
if (name == 'up') {
$(this).fadeIn(200).html;
$.ajax({
type: "POST",
url: "vote_up.php",
data: dataString,
cache: false,
success: function (html) {
parent.parent().find(".display-vote").html(html);
}
});
} else {
$(this).fadeIn(200).html;
$.ajax({
type: "POST",
url: "vote_down.php",
data: dataString,
cache: false,
success: function (html) {
parent.parent().find(".display-vote").html(html);
}
});
}
return false;
});
});
and I'm using jQuery infinite scroll to load rest of the pages/posts. I'm using following code in main page and second page which i load rest of the data
('#left').infinitescroll({
navSelector: '#page-nav', // selector for the paged navigation
nextSelector: '#page-nav a', // selector for the NEXT link (to page 2)
itemSelector: '.post-box', //
}, function (newElements, data, url) {
$(".vote").click(function () {
var id = $(this).data("id");
var name = $(this).data("name");
var dataString = 'id=' + id;
//var dataId = id;
var parent = $(this);
if (name == 'up') {
$(this).fadeIn(200).html;
$.ajax({
type: "POST",
url: "vote_up.php",
data: dataString,
cache: false,
success: function (html) {
parent.parent().find(".display-vote").html(html);
}
});
} else {
$(this).fadeIn(200).html;
$.ajax({
type: "POST",
url: "vote_down.php",
data: dataString,
cache: false,
success: function (html) {
parent.parent().find(".display-vote").html(html);
}
});
}
return false;
});
});
Issue is after 2nd 3rd or any other page load, vote function is triggering twice. How can I fix this issue. Any help will be appreciated.
Maybe if you unbind the click event and then bind it
function(newElements, data, url){
$(".vote").unbind( "click" );
$(".vote").click(function() {
You need to unbind the click event before binding it again.
[...]
$(".vote").unbind('click').click(function()
[...]
or
[...]
$(".vote").off('click').click(function()
[..]
depending on the version of jQuery you are using.
This is my Javascript below I want to show records on load and also show new records when added to the database
showrecords(); displays the records in the database where abouts can I put this in my code where it will work correctly.
$(document).ready(function()
{
//showrecords()
function showrecords()
{
$.ajax({
type: "POST",
url: "demo_show.php",
cache: false,
success: function(html){
$("#display").after(html);
document.getElementById('content').value='';
$("#flash").hide();
}
});
}
$(".comment_button").click(function() {
var element = $(this);
var test = $("#content").val();
var dataString = 'content='+ test;
if(test=='')
{
alert("Please Enter Some Text");
}
else
{
$("#flash").show();
$("#flash").fadeIn(400)
.html('<img src="http://tiggin.com/ajax-loader.gif" align="absmiddle"> <span class="loading">Loading Comment...</span>');
$.ajax({
type: "POST",
url: "demo_insert.php",
data: dataString,
cache: false,
success: function(html){
// $("#display").after(html);
document.getElementById('content').value='';
$("#flash").hide();
//Function for showing records
//showrecords();
}
});
}
return false;
});
});
Though polluting the global namespace is not recommended. Here is what I would recommend for your code. Move the showRecords() out of Document ready function and refactor the update ajax code to another function 'updateRecords()'. Have only the event bindings inside the document ready function.
You could return the entire comments as response to POST 'demo_insert.php' service and call 'showRecords()' in the update service success callback.
i've pasted below (untested) code that i think should get the job done. in order to call functions you've got to define them in an accessible area, whether in the "global" (can be called from anywhere) namespace as i've done below, or as part of an another object.
you also need to make sure your functions are defined before you try to call them, as everything works in a top down manner.
function showrecords() {
$.ajax({
type: "POST",
url: "demo_show.php",
cache: false,
success: function (html) {
$("#display").after(html);
$('content').val('');
$("#flash").hide();
}
});
}
function addComment() {
var test = $("#content").val();
var dataString = 'content=' + test;
if (test == '') {
alert("Please Enter Some Text");
}
else {
$("#flash").show();
$("#flash").fadeIn(400)
.html('<img src="http://tiggin.com/ajax-loader.gif" align="absmiddle"> <span class="loading">Loading Comment...</span>');
$.ajax({
type: "POST",
url: "demo_insert.php",
data: dataString,
cache: false,
success: function (html) {
//$("#display").after(html);
$('content').val('');
$("#flash").hide();
//Function for showing records
showrecords();
}
});
}
}
$(document).ready(function () {
showrecords()
$(".comment_button").click(function () {
addComment();
return false;
});
});
