Can't set HTML using jQuery - javascript

For some reason, my script isn't writing out the text after I remove the textbox element. Am I incorrectly using the .html or is something else wrong?
$('.time').click(function () {
var valueOnClick = $(this).html();
$(this).empty();
$(this).append("<input type='text' class='input timebox' />");
$('.timebox').val(valueOnClick);
$('.timebox').focus();
$('.timebox').blur(function () {
var newValue = $(this).val();
var dataToPost = { timeValue: newValue };
$(this).remove('.timebox');
if (valueOnClick != newValue) {
$.ajax({
type: "POST",
url: "Test",
data: dataToPost,
success: function (msg) {
alert(msg);
$(this).html("88");
}
});
} else {
// there is no need to send
// an ajax call if the number
// did not change
alert("else");
$(this).html("88");
}
});
});
OK, thanks to the comments, I figured out I was referencing the wrong thing. The solution for me was to change the blur function as follows:
$('.timebox').blur(function () {
var newValue = $(this).val();
var dataToPost = { timeValue: newValue };
if (valueOnClick != newValue) {
$.ajax({
type: "POST",
url: "Test",
data: dataToPost,
success: function (msg) {
}
});
} else {
// there is no need to send
// an ajax call if the number
// did not change
}
$(this).parent().html("8");
$(this).remove('.timebox');
});

$(this) in your success handler is refering to msg, not $('.timebox') (or whatever element that you want to append the html to)

$(this) = '.timebox' element but you have removed it already,
$.ajax({
type: "POST",
url: "Test",
data: dataToPost,
success: function (msg) {
alert(msg);
$(this).html("88"); // This = msg
}
and
else {
// there is no need to send
// an ajax call if the number
// did not change
alert("else");
$(this).html("88"); // this = '.timebox' element but you have removed it already,
}

The value of this changes if you enter a function. So when u use this in the blur function handler, it actually points to '.timebox'
$('.time').click(function () {
var valueOnClick = $(this).html();
var $time=$(this);//If you want to access .time inside the function for blur
//Use $time instead of$(this)
$(this).empty();
$(this).append("<input type='text' class='input timebox' />");
$('.timebox').val(valueOnClick);
$('.timebox').focus();
$('.timebox').blur(function () {
var newValue = $(this).val();
var dataToPost = { timeValue: newValue };
$(this).remove(); //Since $(this) now refers to .timebox
if (valueOnClick != newValue) {
$.ajax({
type: "POST",
url: "Test",
data: dataToPost,
success: function (msg) {
alert(msg);
$(this).html("88");
}
});
} else {
// there is no need to send
// an ajax call if the number
// did not change
alert("else");
$(this).html("88");
}
});
});

How to have another "alert" for every form in ajax requesting?

let getLoginPassSystem = function (getPassForgotSystem, getLoginCheckSystem) {
$(document).ready(function () {
$('#login,#lostpasswordform,#register').submit(function (e) {
e.preventDefault();
$.ajax({
type: "POST",
url: 'http://www.virtuelles-museum.com.udev/spielelogin/logsystem.php',
data: $(this).serialize(),
success: function (response) {
var data = JSON.parse(response);
if (data.success == "accepted") {
document.getElementById('inner').innerHTML = 'Herzlich Willkommen';
// location.href = 'index.php';
} else {
alert('Ungültige Email oder Password!');
}
}
});
});
})
}
Well, I want to have for every form(#login,#lostpasswordform,#register) an different "alert". Is it actually possible?
You can save an alert massage in each div tag as data attribute. For example:
<div id="login" data-msg="message1"></div>
<div id="lostpasswordform" data-msg="message2"></div>
<div id="register" data-msg="message3"></div>
// then you can invoke them like this
let getLoginPassSystem = function (getPassForgotSystem, getLoginCheckSystem) {
$(document).ready(function () {
$('#login,#lostpasswordform,#register').submit(function (e) {
e.preventDefault();
let current_form = $(this);
$.ajax({
type: "POST",
url: 'http://www.virtuelles-museum.com.udev/spielelogin/logsystem.php',
data: $(this).serialize(),
success: function (response) {
var data = JSON.parse(response);
if (data.success == "accepted") {
document.getElementById('inner').innerHTML = 'Herzlich Willkommen';
// location.href = 'index.php';
} else {
alert(current_form.attr('data-msg'));
}
}
});
});
})
}
It seems like you can simply check the e.target - it will be different for every form.
You can get more information about Event.target here: https://developer.mozilla.org/en-US/docs/Web/API/Event/target

Ajax change variable automatically

I got an issue here. I found out that the global variable got changed every time it got into ajax.
$(document).on("keyup input", ".product-id", function () {
var id_prod = this.id.replace('prod_id_', '');
console.log('id_prod (outside ajax): ', id_prod);
var inputVal = $(this).val();
var resultDropdown = $('#result2').css({
"display": "block"
});
if (inputVal.length) {
$.ajax({
type: 'POST',
data: { term: inputVal },
url: 'backend-search-inv.php',
success: function (data) {
resultDropdown.html(data);
$(document).on("click", "#result2 p", function () {
var inv_id = $(this).text();
//console.log('inv_id: ',inv_id);
$.ajax({
type: 'POST',
data: {
term: inv_id
},
url: 'autocomplete_inv.php',
success: function (response) {
var inv_info = jQuery.parseJSON(response);
console.log('id_prod (in ajax): ', id_prod);
},
error: function () {
console.log('Unable to access database.');
}
});
}); //end of result being clicked
}
});
}
else {
resultDropdown.empty();
}
});
I don't get it why the variable id_prod gets incremented everytime when it goes into ajax. Here is the screenshot of the console.log.
Referring to the screenshot, everytime I want to enter something to the id_prod = 2, the ajax always ended up updating the id_prod = 1, and then id_prod = 2 again automatically, and result in duplication of my data.
Can someone help me on this?
So basically I just declare the id_prod as a global variable and assigned 0 as it's default value. Then, for id_prod is basically assigned to new value once it's in the keyup input event.
Thanks to Mohamed Yousef for his answer in my own question's comment section!
//DECLARE id_prod as a global variable...
var id_prod = 0;
$(document).on("keyup input", ".product-id", function(){
id_prod = this.id.replace('prod_id_', '');
var inputVal = $(this).val();
var resultDropdown = $('#result2').css({"display":"block"});
if(inputVal.length){
$.ajax({
type: 'POST',
data: {term:inputVal},
url: 'backend-search-inv.php',
success: function(data){
resultDropdown.html(data);
}
});
}
else{
resultDropdown.empty();
}
});
// WHEN RESULT BEING CLICKED...
$(document).on("click", "#result2 p", function(){
var inv_id = $(this).text();
$.ajax({
type: 'POST',
data: {term:inv_id},
url: 'autocomplete_inv.php',
success: function (response) {
var inv_info = jQuery.parseJSON(response);
console.log('id_prod (in ajax): ',id_prod);
$('#prod_id_'+id_prod).val(inv_info[0]);
$('#prod_qty_'+id_prod).val(1);
$('#prod_disct_'+id_prod).val(0);
$('#prod_type_'+id_prod).val(inv_info[1]);
$('#prod_colour_'+id_prod).val(inv_info[2]);
$('#prod_price_'+id_prod).val(inv_info[3]);
$('#result2').empty();
sumPrice();
},
error: function(){
console.log('Unable to access database.');
}
});});

jQuery AJAX get value from .each function and send it to AJAX

How to set jQuery AJAX outside .each on my script below?
$('#btnUpdate').click(function()
{
$('#result').html('');
$('.moduleIDInput').each(function()
{
var uid = $(this).attr('id');
var moduleID = $(this).val();
var chk = new Array();
$('#result').append('<h3>' +$(this).val() + '</h3>');
$('input[data-uid=' + uid + ']:checked').each(function()
{
chk.push($(this).val());
$('#result').append('<div>'+ $(this).val() + '</div>');
});
});
$.ajax(
{
url: "updateGroupAccess.php",
type: "POST",
data:
{
moduleID: moduleID,
chk: chk
},
dataType: "JSON",
success: function (jsonStr)
{
$("#btnUpdate").attr({disabled: true, value: "Update"}).addClass('btn_inact').removeClass('btn_act');;
}
});
});
If I put the AJAX function inside .each function it will submit more than 1.
But I need to put it outside, and found problem moduleID and chk not found.
Scope problem. Define uid and moduleID outside the click.
var uid="";
var moduleID="";
$('#btnUpdate').click(function()
{
$('#result').html('');
$('.moduleIDInput').each(function()
{
uid = $(this).attr('id'); // Assign value for uid
moduleID = $(this).val();
Define the variables in the global scope:
make a function called sendAjax and call it on button click.
In the mean time all your data will be stored in the data global variable (object).
var data={};
$('#btnUpdate').click(function()
{
$('#result').html('');
$('.moduleIDInput').each(function()
{
var uid = $(this).attr('id');
data.moduleID = $(this).val();
$('#result').append('<h3>' +$(this).val() + '</h3>');
$('input[data-uid=' + uid + ']:checked').each(function()
{
data.chk.push($(this).val());
$('#result').append('<div>'+ $(this).val() + '</div>');
});
});
sendAjax();
});
function sendAjax()
{
$.ajax(
{
url: "updateGroupAccess.php",
type: "POST",
data:
{
moduleID: data.moduleID,
chk: data.chk
},
dataType: "JSON",
success: function (jsonStr)
{
$("#btnUpdate").attr({disabled: true, value: "Update"}).addClass('btn_inact').removeClass('btn_act');;
}
});
}

Waiting for Ajax called DOM manipulation to finish

Sorry for the title but I had no idea how to call it.
I got some ajax call function that on success adds some HTML elements to the page:
function ajax_submit_append(form_data, url, result, complete) {
$.ajax({
url: url,
type: 'POST',
data: form_data,
success: function(msg) {
var res = $(msg).filter('span.redirect');
if($(res).html() != null){
window.location.replace($(res).html());
return false;
}
$(result).append(msg);
},
complete: complete()
});
};
Function does something on success where the most important is the .append and then this ajax function is called in some button .click function like this:
$(function() {
$("#product_list_add_btn").click(function(e){
ajax_submit_append(
form_data = {
product_name: $('.selectpicker option:selected').val(),
amount: $('#amount').val()},
"<?php echo site_url('admin_panel/new_order/add_product'); ?>",
'#add_product_result',
calculateSum
);
return false;
});
});
What I want to achieve is that calculateSum function (sums table columns) is called after .append is done via ajax.
For now, when I add calculateSum to ajax complete event it is still called before new row is added to the table with .append
Edit: I present You calculateSum, but I believe there is nothing faulty there.
function calculateSum() {
var sum = 0;
// iterate through each td based on class and add the values
$(".countit").each(function() {
var value = $(this).text();
// add only if the value is number
if(!isNaN(value) && value.length != 0) {
sum += parseFloat(value);
}
});
$('#total_price').text(sum);
alert("test");
};
If I had to guess, I would say its something with click event?
How to fix this?
Try using jqXHR's done() method:
function ajax_submit_append(form_data, url, result, complete) {
$.ajax({
url: url,
type: 'POST',
data: form_data,
success: function(msg) {
var res = $(msg).filter('span.redirect');
if($(res).html() != null){
window.location.replace($(res).html());
return false;
}
$(result).append(msg);
}
}).done(complete);
};

Jquery with variable selector doesn't work

I don't know why the selector jquery doesn't accept a variable.
function myfunction()
{
$.ajax({
url: "/file.php", dataType: "json", type: "GET",
success: function(data)
{
var data = data.split("-");
data.forEach(function(entry)
{
if (entry != "")
{
$("#check_status_" + entry).html('text');
}
});
}
});
}
variable entry is not empty, the problem is when I put it into the selector.
Thanks.
[update]
{
var test = "aaa-bbb-ccc";
var data = test.split("-");
data.forEach(function(entry) {
if (entry != ""){
$("#check_status_" + entry).html('!NEW!');
}
});
}
nothing the same
It seems to work fine if you are achieving something like this
data.forEach(function(entry) {
if (entry) {
$("#check_status_" + entry).html('text');
}
});
