JS/POST/AJAX success - loosing other js functionalities on page - javascript

I have such script that works ok but after success I cannot do anything with the js until refresh the page.
My code looks as follow:
<script>
$("#submit_comment").click(function() {
var url = "{$sitepath}/comment.php"; // the script where you handle the form input.
$.ajax({
type: "POST",
url: url,
data: $("#cform0").serialize(), // serializes the form's elements.
success: function(data)
{
$("#myHeader").load(location.href + " #myHeader > *", "");
}
});
return false; // avoid to execute the actual submit of the form.
});
</script>
It works if I change the
$("#myHeader").load(location.href + " #myHeader > *", "");
to:
$("#myHeader").load("#myHeader");
but then myHeader appears again in myHeader on page.
The question. Is there any possible to load the myHeader and keep the JS on site(sesion)?
Thanks for any suggestions.

AJAX post method working in one area but not another

I have an AJAX post method that works in two places both on "Ladder" page, but not another, a "matches" page. This method sets posts the "player ID" which php picks up and sets a session variable
$("form .singles-player-name").click(function (evt) {
evt.preventDefault();
var viewPlayer = $(this).val();
console.log(viewPlayer);
$.ajax({
url: '',
type: 'POST',
data: {
viewPlayerID: viewPlayer
}
}).done(function (data) {
console.log("Success");
//console.log(data);
window.location.href = "Player";
});
});
Working page form:
<form><button type='submit' id='playerInfo' class='singles-player-name' name='viewPlayer' value='",$sglsPlayerID,"'>", $curSGLSRankLName, ", ", $curSGLSRankFName, "</button></form>
Sets session variable
if (!empty($_POST['viewPlayerID'])){
$viewPlayer = isset($_POST['viewPlayerID']) ? $_POST['viewPlayerID'] : 'No data found';
$viewPlayerSql = "SELECT * FROM `PLAYERS` WHERE `ID` LIKE '".$viewPlayer."'";
$viewPlayerQuery = #$conn->query($viewPlayerSql);
$viewPlayerRow=mysqli_fetch_assoc($viewPlayerQuery);
$_SESSION['playerID'] = $viewPlayerRow["ID"];
echo "", $_SESSION['playerID'],"";}
Second working version that lives on the same page as the first but is for doubles players:
$("form .doubles-player-name").click(function (evt) {
evt.preventDefault();
var viewPlayer = $(this).val();
console.log(viewPlayer);
$.ajax({
url: '',
type: 'POST',
data: {
viewPlayerID: viewPlayer
}
}).done(function (data) {
console.log("Success");
//console.log(data);
window.location.href = "Player";
});
});
Form for that ajax method:
<form><button type='submit' id='playerInfo' class='doubles-player-name' name='viewPlayer' value='",$dblsPlayerID,"'>", $curDBLSRankLName, ", ", $curDBLSRankFName, "</button></form>
Then on complete, the ajax methods redirect to the player page and pulls up that players info on that page (ex. https://urlexample.com/Player). This part, from this point-up, works! However, I have another page, the "Matches" page, where I want it to do the same exact thing, and set that session variable, then redirect to the player page, so I have this method below. But for some reason, this one does not work:
$("form .singlesMatch-player1-name").click(function (evt) {
evt.preventDefault();
var viewPlayer = $(this).val();
console.log(viewPlayer);
$.ajax({
url: '',
type: 'POST',
data: {
viewPlayerID: viewPlayer
}
}).done(function (data) {
console.log("Success");
console.log(data);
window.location.href = "Player";
});
});
Not working form:
<form><button type='submit' id='playerInfo' class='singlesMatch-player1-name' name='viewPlayer' value='",$sglsPlayer1ID,"'>", $P1LN, ", ", $P1FN, "</button></form>
For some reason, all this second method does is post it to the URL (ex. https://urlexample.com/WeeklyMatchUps?viewPlayer=1) instead of setting the session variable and redirecting to the player page (ex. https://urlexample.com/Player). All thats different between the 2 is the class name of the button.
$sglsPlayer1ID should probably be $sglsPlayerID.
Also, try adding a success and error condition to your AJAX conditions instead of just using a done operator. This will allow you to dump helpful error codes on a failure to better resolve these kinds of issues in the future.
I had a function being called on the page that was commented out causing an error before jQuery was added in a script at the bottom of the page. removing that function from being called fixed the issue.

Add javascript function to wordpress page

I have a page that locates a link inside it and when that link is clicked it should save some data in database.
Besides, I have a file named "add.php" that communicates with the DB and operates well.
In my wordpress page I have added below codes for accessing the add.php file and send some parameters to it.
<a href="javascript:add(true);" >Click Me</a>
<script type="text/javascript">
function add(b){
$(document).ready(function(){
var result = $.ajax({
type: "POST",
url: "add.php",
data: { add: b }
});
result.done(function(msg) {
alert(msg);
});
result.fail(function(jqXHR, textStatus) {
alert( "No such data exists: " + textStatus );
});
});
}
</script>
I had this exact code in an html file and it worked smoothly. but it doesn't work on wordpress page like that.
Plus, the problem is that when I click the link -Click Me- it doesn't do anything.
please tell me where the problem is and how to solve it ?
I would recommend you to use this:
<a href="#" data-add="true" class='hitClick'>Click Me</a>
<!--use data* attributes to pass specific data -->
now in your function:
function add() {
event.preventDefault(); //<------make sure to add it.
var result = jQuery.ajax({
type: "POST",
url: "add.php",
data: {
add: jQuery(this).data('add')
}
});
result.done(function(msg) {
alert(msg);
});
result.fail(function(jqXHR, textStatus) {
alert("No such data exists: " + textStatus);
});
}
jQuery(document).ready(function(){
jQuery('.hitClick').on('click', add); // bind the click and use as callback
});

Getting a success info after submitting form via $.ajax in jquery

I have a few forms on my single page and I'm submitting them by this method:
$(function() {
$(".button").click(function() {
var upform = $(this).closest('.upform');
var txt = $(this).prev(".tekst").val();
var dataString = 'tekst='+ txtr;
$.ajax({
type: "POST",
url: "http://url-to-submit.com/upload/baza",
data: dataString,
success: function() {
upform.html("<div class='message'></div>");
$('.message').html("<h2>FORM SUBMITTED</h2>")
.append("<p>THANKS!!</p>")
.hide()
.fadeIn(1500, function() {
$('.message').append("<img src='http://my-images.com/i/check.png' />");
});
}
});
return false;
});
});
As you can see, after submit a form, message div appears instead of submitted form.
It works perfectly, when I submit only one form - then it changes to my message div, but when I submit second, and next and next - every time ALL of my already submitted form's messages refreshing.
It looks bad. I want to operate only on actually submitting form. How to fix it?
Well you're setting the message of every .message div by using $('.message').html(). Try this:
upform.find('.message').html(...)
Hard to tell without seeing how your HTML looks but i'm guessing it's this bit,
$('.message')
Should be something like,
$('.message', upForm).
First you have to find out the message div (upform.find('.message')) and than add any html to it. i think your code should be
$(function() {
$(".button").click(function() {
var upform = $(this).closest('.upform');
var txt = $(this).prev(".tekst").val();
var dataString = 'tekst='+ txtr;
$.ajax({
type: "POST",
url: "http://url-to-submit.com/upload/baza",
data: dataString,
success: function() {
upform.html("<div class='message'></div>");
upform.find('.message').html("<h2>FORM SUBMITTED</h2>")
.append("<p>THANKS!!</p>")
.hide()
.fadeIn(1500, function() {
upform.find('.message').append("<img src='http://my-images.com/i/check.png' />");
});
}
});
return false;
});
});
Another way without editing more in your current code just add few lines.
var msgbox = $("<div class='message'></div>");
upform.html(msgbox);
msgbox.html("<h2>FORM SUBMITTED</h2>")
.append("<p>THANKS!!</p>")
.hide()
.fadeIn(1500, function() {
$(this).append("<img src='http://my-images.com/i/check.png' />");
});

.ajax() refreshes the page after ENTER is hit

I am using ajax to update the db with a new folder but it refreshes the page after ENTER is hit.
on my form I have onkeypress="if(event.keyCode==13) savefolder();"
here is the javascript code that I have: what it does basically is after you hit enter it calls the function savefolder, savefolder then sends a request through ajax to add the folder to the db. Issue is it refreshes the page... I want it to stay on the same page.
any suggestions? Thank you
<script>
function savefolder() {
var foldername= jQuery('#foldername').val(),
foldercolor= jQuery('#foldercolor').val();
// ajax request to add the folder
jQuery.ajax({
type: 'get',
url: 'addfolder.php',
data: 'foldername=' + foldername + '&foldercolor=' + foldercolor,
beforeSend: function() { alert('beforesend');},
success: function() {alert('success');}
});
return false;
}
</script>
This is working:
<form>
<input type="submit" value="Enter">
<input type="text" value="" placeholder="search">
</form>
function savefolder() {
var foldername= jQuery('#foldername').val(),
foldercolor= jQuery('#foldercolor').val();
jQuery.ajax({
type: 'get',
url: '/echo/html/',
//data: 'ajax=1&delete=' + koo,
beforeSend: function() {
//fe('#r'+koo).slideToggle("slow");
},
success: function() {
$('form').append('<p>Append after success.</p>');
}
});
return false;
}
jQuery(document).ready(function() {
$('form').submit(savefolder);
});

You need to check to see if you're having any errors during processing (Firebug or Chrome Console can help). As it stands, your code is not well-formed, as the $(document).ready() is never closed in the code you included in the question.
Simply stop the propagation of the event at the time of the form submission
jQuery(document).ready(function($) {
$("#whatever-form-you-are-pulling-your-values-from").submit(function(event) {
var foldername = $('#foldername').val();
var foldercolor = $('#foldercolor').val();
event.stopPropagation();
// ajax request to add the folder
$.ajax({
type: 'get',
url: '../addfolder.php',
data: 'ajax=1&delete=' + koo,
beforeSend: function() { fe('#r'+koo).slideToggle("slow"); },
success: function() { }
});
});
Since by default on a form the enter button submits the form, you need to not only handle this with your own code, but cancel the event after.
Try this code instead:
onkeypress="if(event.keyCode==13) {savefolder(); return false;}"
The onkeypress event will that the return value of the javascript and only continue with it's events if it returns true.

What does this Javascript Sign up Code do?

It is related to an ajax/jquery 1.3.2 based sign up form. I want to learn how to make this and use jquery in general by understanding the code/syntax line by line.
Can someone explain what this code is trying to accomplish and how it does so line by line?
<script type="text/javascript">
$(document).ready(function(){
// Email Signup
$("form#sub_name").submit(function() {
var dataStr = $("#UserEmail").val();
$.ajax({
type: "POST",
url: "signup.php",
data : {UserEmail: dataStr},
success: function(del){
$("#signup-success").html(del);
$("#signup-success").fadeIn();
$('#signup-success').fadeOut(10000);
}
});
return false;
});
});
Thanks!
Code explained in the comments.
<script type="text/javascript">
$(document).ready(function(){ // run this code on page load
// Email Signup
$("form#sub_name").submit(function() { // activate on form submit for sign in
// the id of the form is sub_name
var dataStr = $("#UserEmail").val(); // get the email address from an
// input field with ID UserEmail
$.ajax({ // use and ajax call to signup.php
// using POST method
type: "POST",
url: "signup.php",
data : {UserEmail: dataStr}, // The parameter UserEmail is passed.
success: function(del){ // this part displays the success
$("#signup-success").html(del); // probably a div with id signup-success
$("#signup-success").fadeIn(); // is faded in and
$('#signup-success').fadeOut(10000); // removed after 10 seconds
}
});
return false;
});
});
