I am submitting a form via an ajax post request but there is a possibility that there is also one get parameter and if the get parameter is set it must be included in the post request.
I currently have this:
jQuery(document).ready(function($) {
$("#plugin_check").submit(function(e) {
e.preventDefault(); // avoid to execute the actual submit of the form.
var form = $(this);
var actionUrl = form.attr('action');
$.ajax({
type: "POST",
cache: false,
url: actionUrl,
data: form.serialize(), // serializes the form's elements.
success: function(data)
{
$("#result").html(data); // show response from the php script.
}
});
});
});
I need to figure out how to put $_GET['datesort'] into the post data.
you can try this, create variable to save datesort and add this to ajax data
jQuery(document).ready(function($) {
$("#plugin_check").submit(function(e) {
e.preventDefault(); // avoid to execute the actual submit of the form.
var form = $(this);
var actionUrl = form.attr('action');
var queryString = window.location.search;
var urlParams = new URLSearchParams(queryString);
var datesort = urlParams.get('datesort')
$.ajax({
type: "POST",
cache: false,
url: actionUrl,
data: form.serialize() + `&datesort=${datesort}`, // serializes the form's elements.
success: function(data) {
$("#result").html(data); // show response from the php script.
}
});
});
});

I have a button by where onclick i am trying to send the form data to the server page to process. but somehow the formdata is going empty
can anyone guide what i am doing wrong here, here is my code

console.log(obj);
var form = document.querySelector('form');
var data = new FormData(form);
var post_url = $('#formid').attr("action"); //get form action url
var form_data = $('#formid').serialize() & '&yes=1'; //Encode form elements for submission
console.log(form_data);
console.log(data);
$.post(post_url, form_data, function( response ) {

the function ajax is called on the button click inside a form
You are using post menthod wich gets params in body serilliazing the args like that is good for GET request you should send in body just use a object holding all the info
$.ajax({
type: "POST",
url: url,
data: data ,// object
success: success,
dataType: dataType
});
I'm having an issue with AJAX as for some reason it either isn't being called or isn't working
$(document).ready(function() {
$("#my_form").submit(function(event) {
alert("submited");
event.preventDefault("#my_form");
var post_url = $(this).attr("action"); //get form action url
var request_method = $(this).attr("method"); //get form GET/POST method
var form_data = $(this).serialize(); //Encode form elements for submission
alert(post_url + "" + request_method + " " + form_data);
$.ajax({
type: post_url,
url: request_method,
data: form_data,
success: function(data) {
alert(data);
$("server-results").html(data);
}
});
$('#loadingDiv').hide().ajaxStart(function() {
$(this).show();
});
//.ajaxStop(function() {
// $(this).hide();
//});
});
});
I've debugged as much as I could and there is no issue with the form function being activated in JavaScript or the 3 variables being transported into the JS code block. However ajaxStart doesn't activate which makes me believe that the problem is with just ajax.
I also checked the link to ajax and it seems to be working however I'm not sure if its the right link or if it's not valid for whatever reason.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
FYI the ajax link is at the top of the page above both HTML and JS.
You have passed wrong parameters:
type: post_url,
url: request_method,
You need to pass post_url in url and request_method in type. Just change it to:
type: request_method,
url: post_url,
$("server-results").html(data); here you have not specified if server-results is a class or id and therefore the output of the server will never be printed on the page
jQuery .ajaxStart()
As reported in jQuery's official documentation, the ajaxStart event can not be activated by the #loadingDiv element, but you must use the document.
$( document ).ajaxStart(function() {
$( ".log" ).text( "Triggered ajaxStart handler." );
});
Summing up the code should be something like this.
$(document).ready(function() {
$("#my_form").submit(function(event) {
alert("submited");
event.preventDefault("#my_form");
var post_url = $(this).attr("action"); //get form action url
var request_method = $(this).attr("method"); //get form GET/POST method
var form_data = $(this).serialize(); //Encode form elements for submission
alert(post_url + "" + request_method + " " + form_data);
$.ajax({
type: post_url,
url: request_method,
data: form_data,
success: function(data) {
alert(data);
$(".server-results").html(data);
}
});
$(document).ajaxStart(function() {
$('#loadingDiv').show();
});
.ajaxStop(function() {
$('#loadingDiv').hide();
});
});
});
alright, I have a popup which displays some notes added about a customer. The content (notes) are shown via ajax (getting data via ajax). I also have a add new button to add a new note. The note is added with ajax as well. Now, the question arises, after the note is added into the database.
How do I refresh the div which is displaying the notes?
I have read multiple questions but couldn't get an answer.
My Code to get data.
<script type="text/javascript">
var cid = $('#cid').val();
$(document).ready(function() {
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "ajax.php?requestid=1&cid="+cid,
dataType: "html", //expect html to be returned
success: function(response){
$("#notes").html(response);
//alert(response);
}
});
});
</script>
DIV
<div id="notes">
</div>
My code to submit the form (adding new note).
<script type="text/javascript">
$("#submit").click(function() {
var note = $("#note").val();
var cid = $("#cid").val();
$.ajax({
type: "POST",
url: "ajax.php?requestid=2",
data: { note: note, cid: cid }
}).done(function( msg ) {
alert(msg);
$("#make_new_note").hide();
$("#add").show();
$("#cancel").hide();
//$("#notes").load();
});
});
</script>
I tried load, but it doesn't work.
Please guide me in the correct direction.
Create a function to call the ajax and get the data from ajax.php then just call the function whenever you need to update the div:
<script type="text/javascript">
$(document).ready(function() {
// create a function to call the ajax and get the response
function getResponse() {
var cid = $('#cid').val();
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "ajax.php?requestid=1&cid=" + cid,
dataType: "html", //expect html to be returned
success: function(response) {
$("#notes").html(response);
//alert(response);
}
});
}
getResponse(); // call the function on load
$("#submit").click(function() {
var note = $("#note").val();
var cid = $("#cid").val();
$.ajax({
type: "POST",
url: "ajax.php?requestid=2",
data: {
note: note,
cid: cid
}
}).done(function(msg) {
alert(msg);
$("#make_new_note").hide();
$("#add").show();
$("#cancel").hide();}
getResponse(); // call the function to reload the div
});
});
});
</script>
You need to provide a URL to jQuery load() function to tell where you get the content.
So to load the note you could try this:
$("#notes").load("ajax.php?requestid=1&cid="+cid);
I have a page where is 3-4 form in divs, and I want to submit it with only one script and I want to refresh the actual div content (where is the form). But I don't know how to specify the actual div or form for the ajax post.
$(document).ready(function(){
$(".ajaxform").submit(function() {
var id = $(this).attr('id');
var dataString = $(this).serialize();
$.ajax({
url:'../tools/tools.php',
data: dataString + '&form=' + id,
type: 'POST',
success: function(html)
{
$('#actualdiv').load(document.URL + ' #actualdiv');
}
});
});
});
The forms or divs have unique id for the tools.php where I can run the actual form's mysql.
Since you are posting data and then receiving new forms back as a response, I would make the function more dynamic.
function loadNextForm(form, id){
var dataString = form.serialize();
$.ajax({
url:'../tools/tools.php',
data: dataString + '&form=' + id,
type: 'POST',
success: function(newForm) {
$('#actualdiv').html(newForm);
}
});
}
$(document).ready(function(){
$(".ajaxform").on("submit", function(){
loadNextForm($(this), $(this).attr('id'));
});
});
This should allow you to POST the data, get the new form, place it into the DIV, and allow it to be a functional form that can process the next form.
Hi i have jquery request like below ,
$('#filterForm').submit(function(e){
e.preventDefault();
var dataString = $('#filterForm').serialize();
var class2011 = document.getElementById("2011").className;
//var validate = validateFilter();
alert(dataString);
if(class2011=='yearOn')
{
dataString+='&year=2011';
document.getElementById("2011").className='yearOff';
}
else
{
document.getElementById("2011").className='yearOn';
}
alert (dataString);
$.ajax({
type: "POST",
url: "myServlet",
data: dataString,
success: function(data) {
/*var a = data;
alert(data);*/
}
});
and my Form is like ,
<form method="post" name="filterForm" id="filterForm">
<!-- some input elements -->
</form>
Well, I am triggering jquery submit on submit event of a form ,(it's working fine)
I want pass one extra parameter inside form which is not in above form content but it's outside in page
it's like below
[Check this image link for code preview][1]
So how can i trigger above event , on click of , element with class yearOn ( check above html snippet ) and class yearOff , with additional parameter of year set to either 2011 or 2010
$(document).ready(function () {
$('#filterForm').submit(function (e) {
e.preventDefault();
var dataString = $('#filterForm').serialize();
if ($("#2011").hasClass('yearOn')) {
dataString += '&year=2011';
$("#2011").removeClass('yearOn').addClass('yearOff');
}
else {
$("#2011").removeClass('yearOff').addClass('yearOn');
}
$.ajax({
url: "/myServlet",
type: "POST",
data: dataString,
success: function (data) {
/*var a = data;
alert(data);*/
}
});
});
});
1.) If you are using jQuery already, you can use the $.post() function provided by jquery. It will make your life easier in most cases.
2.) I have always had a successful post with extra parameters this way:
Build you extra parameters here
commands={
year:'2011'
};
Combine it with your form serialize
var dataString=$.param(commands)+'&'+$("#filterForm").serialize();
Perform your post here
$.post("myServlet",data,
function(data) {
/*var a = data;
alert(data);*/
}
);
OR use $.ajax if you really love it
$.ajax({
type: "POST",
url: "myServlet",
data: dataString,
success: function(data) {
/*var a = data;
alert(data);*/
}
In the end, here is the full code the way you are doing it now
$('#filterForm').submit(function(e){
e.preventDefault();
var class2011 = document.getElementById("2011").className;
//var validate = validateFilter();
alert(dataString);
if(class2011=='yearOn') {
dataString+='&year=2011';
document.getElementById("2011").className='yearOff';
} else {
document.getElementById("2011").className='yearOn';
}
commands={
year:'2011'
};
var dataString=$.param(commands)+'&'+$("#filterForm").serialize();
alert (dataString);
$.ajax({
type: "POST",
url: "myServlet",
data: dataString,
success: function(data) {
/*var a = data;
alert(data);*/
}
});
