I have a ajax query which keeps reloading a div of the page in every 6 seconds.There is a action button in that reloading div which opens a modal.The problem is whenever page reloads the modal also refreshes. And i have to send some information through that modal but i am not able to fill up the modal as the page keeps refreshing every 6 secondsI couldn't find a solution for that. The files are as shown below. file1.php calls file2.php which has a table with dynamic values(i have made them static just for SO.)P.S.: I am also looking to implement a notification system but can't figure out a way to do that. If anyone could help.EDITI want the div to reload every 6 seconds but not the modal
file1.php

Okay, here is your problem:
var modal = document.getElementById('myModal');
Now modal refers to your element.
However, once the ajax request fetches new data, this element gets deleted and replaced by a new element with the same ID.
What you could do is structure the data outputted from SO.php as a JSON-object, and replace only the contents of each HTML-element.
JSON-objects generally look like this:
["This is some text!", "Even more text!"]
If we let text.php return this data,
As a simple example, you could request text.php through AJAX:
function reloadData()
{
url = 'text.php?' + Date.now();
try {
req = new XMLHttpRequest();
} catch (e) {
try {
req = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
req = new ActiveXObject("Microsoft.XMLHTTP");
} catch (oc) {
alert("No AJAX Support");
return;
}
}
}
req.onreadystatechange = processReqChange;
req.open("GET", url, true);
req.send(null);
}
function processReqChange()
{
if (req.readyState == 4)
{
dataDiv = document.getElementById('currentData');
if (req.status == 200)
{
obj = JSON.parse(req.responseText); // This now represents the JSON object.
for(var i = 0; i < obj.length; i++){
dataDiv.getElementsByTagName('p')[i] = obj[i];
}
timeoutID = setTimeout('reloadData()', 6000);
}
else
{
dataDiv.innerHTML = '<p>There was a problem retrieving data: ' + req.statusText + '</p>';
}
}
}
And you do <div id="currentData"><p></p><p></p></div>
The two paragraphs will be filled with the text of whatever text.php returns.
You can also find plenty of tutorials with a simple google search :)

I have this project where the user selects an item from a list (fetched from a MySQL database), then outputs buttons named from the item
as such:

I was able to make a modal for one button but I want to make a unique modal for each button. How can I do this? Thanks.
Write a function which will build a modal for you. Have this function accept some input, like the content of the modal which you want to show. Then add the modal to the page. This way you can generate an infinite amount of different modals based on the button that you click on.
I've made an example below which demonstrates how this could work. The example works with building a modal, with the same structure of your example, and use the value attribute of the button the set the content of that modal. For simple text this works fine, but for larges chunks of HTML you might consider getting your content from a hidden element and copy the innerHTML value of that element.
// Flag for checking if a modal is already opened.
// This way we can keep track of the opened modal and
// not open a second one before closing the first.
let modalOpen = false;
function createModal(html = '') {
// Create the elements.
const modal = document.createElement('div');
const content = document.createElement('div');
const close = document.createElement('span');
// Add classes to the elements.
modal.classList.add('modal');
content.classList.add('modal-content');
close.classList.add('close', 'js-close-modal');
// Add content to the elements.
content.insertAdjacentHTML('beforeend', html);
close.innerHTML = '×';
// Append children to parents and to the document.
content.appendChild(close);
modal.appendChild(content);
document.body.appendChild(modal);
return modal;
}
// Listen for clicks in the document.
document.addEventListener('click', event => {
// If the create modal button has been clicked, create a modal.
const button = event.target.closest('.js-create-modal');
if (button !== null && modalOpen === false) {
const html = button.value;
createModal(html);
modalOpen = true;
}
// If the close modal has been clicked, remove the modal.
const close = event.target.closest('.js-close-modal');
if (close !== null) {
const modal = close.closest('.modal');
modal.remove();
modalOpen = false;
}
});

<button class="js-create-modal" value="This is my first modal.">Modal 1</button>
<button class="js-create-modal" value="All the modals have their own content.">Modal 2</button>
<button class="js-create-modal" value="And are unique in every way.">Modal 3</button>
Another way would be to have a single modal on the page, which you show and hide. Whenever you click a button, you should modify the content of the modal based on the button that you clicked. That way you only have to modify a single piece. But hey, if a modal is hidden, why not just remove it and build a new one when you need it? Your choice.
I'm trying to make this dialog popup for the duration of the execution of the AddConclusionSlide function, but I get the exception: "TypeError: Cannot find function show in object Presentation." Is there an alternative to "show" for Google Slides Script (This works perfectly in google docs)?
function AddConclusionSlide() {
htmlApp("","");
var srcId = "1Ar9GnT8xPI3ZYum9uko_2yTm9LOp7YX3mzLCn3hDjuc";
var srcPage = 6;
var srcSlide = SlidesApp.openById(srcId);
var dstSlide = SlidesApp.getActivePresentation();
var copySlide = srcSlide.getSlides()[srcPage - 1];
dstSlide.appendSlide(copySlide);
Utilities.sleep(3000); // change this value to show the "Running script, please wait.." HTML window for longer time.
htmlApp("Finished!","");
Utilities.sleep(3000); // change this value to show the "Finished! This window will close automatically. HTML window for longer time.
htmlApp("","close"); // Automatically closes the HTML window.
}
function htmlApp (status,close) {
var ss = SlidesApp.getActivePresentation();
var htmlApp = HtmlService.createTemplateFromFile("html");
htmlApp.data = status;
htmlApp.close = close;
ss.show(htmlApp.evaluate()
.setWidth(300)
.setHeight(200));

Unlike Spreadsheet object, Slide object doesn't have a show method. So, class ui needs to be used:
SlidesApp.getUi().showModalDialog(htmlApp.evaluate()
.setWidth(300)
.setHeight(200), "My App")
I am trying to get a modal popup to show "Please Wait" while an Ajax call is being made. The pop up occurs only after the call completes.
When I click my web link, everything is working, except the modal popup that is supposed to say "Please Wait" flashes for a split second AFTER the delay that the user is supposed to be asked to wait thru. That is, the modal pops up AFTER the Ajax call is completed instead of before.
When the page loads, it calls AjaxInitialUpdate. This works fine.
The issue is when you click the button that calls AjaxChangePassword.
The function is supposed to pull up a modal, then contact the web server, before finally removing the model and calling the AjaxInitialUpdate function to refresh the whole screen.
The issue is that the AjaxChangePassword modal doesn't pop up until the web query completes (by which time, there is no point in telling the user -- Please Wait).
Now, I am totally self-taught here, so I may be calling things by the wrong name or terms. I welcome any ideas to make it run better, but please be detailed, I'm still very novice in Java.
Also, the last time I did any kind of HTML programming was before Style sheets were the way to go, so I'm kind of having to learn them as well (and refresh on all the rest, so please explain any answer in detail).
Lastly, the server side of this is written in Powershell and is single threaded so I am trying to put as much in the HTML file as possible instead of calling secondary files, like style sheets and images.

When I call AjaxChangePassword(), I expected the modal to open BEFORE the query.
As it is now, if I stop the server after the page loads, but before this function is started, the modal never pops up, then once I start the server side back up, and I see the query come in and get answers, only then does it pop up, and then only for a split second.
What am I doing wrong in the way I am calling it?
As I reviewed your code and found that in the function AjaxChangePassword firstly you opened modal and then called ajax then closed modal the problem is that basically javascript executes synchronously but if there is ajax call then it executes asynchronously, so according to that your modal opens and then call ajax untill ajax is busy in getting response before that next line will be executed that line is for modal close and this happens in the fraction of ms so you don't see anything, And you said that after ajax call modal is showing because in AjaxChangePassword the call back method is AjaxInitialUpdate and also in this method you opened modal then closed but remember in this method you closed modal in the call back method so it appears for some time and you can see so according to me just remove
document.getElementById('myModal1').style.display = "none";
this line from AjaxChangePassword method below is corrected AjaxChangePassword function
function AjaxChangePassword(){
document.getElementById('myModal1').style.display = "block";
document.getElementById('myModal2').style.display = "none"; // Make sure its not poped up..
// we need to set item on the modal to explain what we are doing...
document.getElementById("ModalTextLine1").innerHTML="Processing password change request. Please Wait"
var xhr = "";
var xhr = new XMLHttpRequest();
// server will check if values are valid..
var Server = document.getElementById("DynServerName").innerHTML;
var AdminID = document.getElementById("DynAdminID").innerHTML;
xhr.open('GET', 'http://PSShellSrv.mydomain.local:80/CyberPass3/?command=update&sub=change&server=' + Server + '/' + AdminID+'&NoCache=' + ((new Date()).getTime()), true);
xhr.responseType = 'text';
xhr.onload = function () {
console.log('Initail Comment Response onpassword change.');
if (xhr.readyState === xhr.DONE) {
if (xhr.status === 200) {
document.getElementById('myModal1').style.display = "none";
console.log(xhr.response);
console.log("Report password changed.");
AjaxInitialUpdate() // password changed, lets refresh.
};
};
};
xhr.send(null);
};
and check. I may be wrong but check it.
I am using two buttons in my web page (http://localhost:8088/hse/public/explorer) :
and those button will open a new pop window : (http://localhost:8088/hse/public/explorer/1)
onClick="MyWindow=window.open('http://localhost:8088/hse/public/explorer/1','MyWindow',width=300,height=200); return false;">Show Map</button>
This button on clicked it will open a new pop window and inside that pop windows, there will be some HTML links, i want when user click on any of those link , the pop windows close and that link open on the same parent page but different URL (http://localhost:8088/hse/public/explorer/show/1)
Try this.
This wont work when you run the "snippet" ... Create a document and use it there instead.
document.getElementById("button").onclick = evt => {
window.open(window.location.origin + "/hse/public/explorer/1", "MyWindow", "width=300, height=200");
}
<button id="button">Open new window</button>
Update:
Try doing this instead what you described down below. This will do the same, but actually makes sense to use. If you want to create something that is ensured to be userfriendly.
var id_button = document.getElementById("button"),
id_container = document.getElementById("container");
id_button.onclick = evt => {
// show or hide container
if (id_container.classList.contains("hide")) {
id_container.classList.remove("hide");
} else {
id_container.classList.add("hide");
}
}
// add onclick-function for every child of "id_container"
for (var i = 0; i < id_container.childElementCount; i++) {
var child_element = id_container.children[i];
child_element.onclick = evt => {
// check that the element is a "a"-element
if (evt.target.localName == "a") {
window.open(window.location.origin + evt.target.getAttribute("data-link"), "_blank");
}
}
}
.container {
border: 1px solid black;
border-radius: 5px;
text-align: center;
padding: 10px;
}
.hide {
display: none;
}
<button id="button">Show/hide all links</button>

I am using this PHP Database Ajax code by W3Schools.com
This is my code, inside the PHP File (as shown in w3schools). It is working in this snippet. Also working, when i use this in the HTML file (as shown in w3schools).
But when, i use this code in the PHP File, it is not working. What could possibly go wrong?
