How to keep view changes after refresh page?

In my MVC application i have a view in which i refresh the page each 10 seconds.
I have some paragraph in the view are hidden and a button which make those paragraphs not hidden.
The problem that when i click on the button to make the paragraph show when the page reload automatically in 10 seconds returns the paragraph hidden.
This is the button:
<button id="button">Display Internal Sequences</button>
This is the paragraph :
<p1 hidden style="text-align:center;font-size: 50px; padding:-25px; margin:-25px;">#Html.Label(#Model.CSLine.ModuleOrderInternalSequence > long.MinValue ? #Model.CSLine.ModuleOrderInternalSequence.ToString() : string.Empty)</p1>
This is the script to make the p not hidden:
<script>
$(document).ready(function () {
$("#button").click(function () {
$("p1").attr("hidden", false);
var show ='true';
localStorage.setItem(key, show);
});
});
</script>
This is the reload each 10 seconds:
setTimeout(function () {
window.location.reload(1);
}, 10000);
$(document).ready(function() {
var show = localStorage.getItem(key);
if (show == 'true')
{
$("p1").attr("hidden", false);
} })
The result is that the paragraph returns hidden after each reload.
I want when i click the button the paragraph became not hidden even after reload.
Thank you

Note: Your page will only reload after 10 seconds in this case and will only refresh once.
If you want the page to refresh every 10 seconds, you should use setInterval instead of setTimeout.
<script>
$(document).ready(function() {
// If you want the page to refresh constantly, you should use setInterval intead of setTimeout. setTimeout fires only once.
setTimeout(function () {
window.location.reload(1);
}, 10000);
$("#button").click(function() {
$("p1").attr("hidden", false);
localStorage.setItem("show_p1", true);
});
if (localStorage.getItem("show_p1") == 'true') {
$("p1").attr("hidden", false);
}
});
</script>
<p1 hidden style="text-align:center;font-size: 50px; padding:-25px; margin:-25px;">#Html.Label(#Model.CSLine.ModuleOrderInternalSequence > long.MinValue ? #Model.CSLine.ModuleOrderInternalSequence.ToString() : string.Empty)</p1>
<button id="button">Display Internal Sequences</button>

if (show = 'true')
This is not a comparison, you are setting the value of "show" to "true". Use == to compare values.

Try using jQuery's prop() method instead of attr() like so:
$("p1").prop("hidden", false);
The jQuery documentation for prop() describes the difference between the two methods, especially for boolean attributes like hidden. Also, here is a post regarding this .prop() vs.attr()

Getting clone() to only work onetime interchangebly

I am trying to get an image to move over to a separate box upon clicking and then to be removed with a remove button I have in my html. I figured out how to add the image upon clicking it then removing it upon clicking the remove button.
The issue I am having is: when I click the image itself, it should copy over to the right but it should only copy one time and then I must .remove() the image using the button before I can click it again so it appears once more. Right now the image appears over and over upon clicking. I tried using .stop() but that stops the function entirely, I need it to work interchangeably. How do I do this using jQuery?
JQUERY CODE:
$(document).ready(function(){
$("#john").click(function(){
var johnImage = $("#john").clone(false);
$("h2").html("John is in the box");
$("h2").css({ 'color': 'red'});
$("#johnbox").prepend(johnImage);
});

Check out the below code. You should be setting clicked to false again in your remove handler.
Here is the full code after I got your remove code.
$(document).ready(function () {
var clicked = false;
$("#john").click(function () {
if (!clicked) {
var johnImage = $("#john").clone(false);
$("h2").html("John is in the box");
$("h2").css({ 'color': 'red' });
$("#johnbox").prepend(johnImage);
clicked = true;
}
});
$("#removejohn").click(function () {
clicked = false;
$("#john").remove();
$("h2").html("Click John to put him in the Box");
$("h2").css({ 'color': 'black' });
});
});

Prevent anchor click after one click

I am facing one issue, I want to disable anchor click after one click. I have
on-click attribute set in my anchor tag. Below is my HTML
<a style="cursor:pointer;" id="someId" onclick="Myfuntion()">Verify</a>
After I click "Verify" I am changing anchors text to "Verifying..." and one more thing I am trying to disable this anchor to avoid click in between the verification logic going on.
I have tried event.preventdefault() and also added disabled attribute to anchor.
But nothing works.
Please help!

If you were using jQuery for this you could have done this more easly.
Here we add a new class to a link to show that it has been clicked already. We check this when a click is made.
<a style="cursor:pointer;" id="someId">Verify</a>
$('#someId').on('click',function(){
//Check if button has class 'disabled' and then do your function.
if(! $(this).hasClass('disabled')){
$(this).addClass('disabled');
Myfuntion();
$(this).removeClass('disabled');
}
});

Here is a demo as to how it could be done using Javascript.
//Pass the event target to the function
function Myfuntion(elem) {
//If the element has no "data-status" attribute
if (!elem.getAttribute("data-status")) {
//Set attribute "data-status=progress"
elem.setAttribute("data-status", "progress");
//Change the text of the element
elem.textContent = "Verifying...";
//The setTimeout(s) below is only for the demp purpose
//Lets say, your verification process takes 4 seconds
//When complte
setTimeout(function() {
//Remove the attribute "data-status"
elem.removeAttribute("data-status");
//Notify the use that verification is done
elem.textContent = "Verified";
//Again, this is only for demo purpose
setTimeout(function() {
//User may verify again
elem.textContent = "Verify";
}, 1000);
}, 4000);
}
return false;
}
Link to the demo

There are plenty of ways to do this; one simple approach is to just redefine the function itself:
var myFunction = function() {
alert('clicked');
// do whatever your function needs to do on first click, then:
myFunction = function() { // redefine it
// to no-op, or to another action
alert('second click');
}
}
<a onclick="myFunction()">click me</a>

How to detect button value change in JQuery?

I've a sign up form which has submit button with value "GET INSTANT ACCESS!" :
<input type="submit" class="wf-button" name="submit" value="GET INSTANT ACCESS!">
After submit, the value gets change to 'Thank You!':
<input type="button" class="wf-button" value="Thank You!">
I need to detect the button value. If it becomes "Thanks You!" then I have to show a popup. And this value gets change by some Ajax (GetResponse form). There is no page refresh.
I've tried below code but it is only working in FireFox & not working in Chrome.
<script>
$(function() {
$(".modalbox").fancybox();
});
$(function() {
$('.wf-button').bind("DOMSubtreeModified",function(){
//if btn valu is 'Thank You! trigger popup'
$(".modalbox").trigger('click');
});
});
</script>
Live URL: http://www.idynbiz.com/web/html/gold_ira_vf/? (just to show how the button changes its value)
Can some one help how can I detect the button value and show my popup? The button change its value in real time (Ajax). There is not page refresh.
Is there any JQuery approach with bind() Or on() function to detect the value?

$(function() {
$('.btn1').on('change', function() {
alert('Do stuff...');
});
$('.lnk1').on('click', function() {
$('.btn1').val('Thank you!');
$('.btn1').trigger('change');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input type="submit" class="btn1" value="SUBSCRIBE" />
Change button value

OK ,
when button is clicked and form is submitted for saving. just write these code
$(document).ready(function ()
{
$('.wf-button').click(function ()
{
var valueofbutton = $(this).attr('value');
if(valueofbutton == 'Thank You!')
{
window.open(); //// whatever you want to open in popup
}
});
});
i m sure that this will work

You can use the following function in javascript which gets called after any > kind of postback, i.e. synchronous or asynchronous.
function pageLoad()
{
if($(".wf-button").val()=="Thank You!")
{
// show your popup
}
}
Hope it works....

Toggling button text in jquery

I have an HTML button created and I want to toggle the text that is displayed in the button between two text using Javascript/JQuery. How do I do this?
Currently, I have:
<button onclick="showAll();" class="collapse-classes">
<span class="button-text">Show</span>
</button>
The button starts off by displaying "Show" and then switch to "Hide" when clicked and then switch to "Show" when clicked again and onward. I tried changing the value of the tag but it doesn't change the text displayed. Can anyone help with the script? thanks

Don't use onclick. Just bind an event handler.
Here's something you can work with:
$('.collapse-classes').click(function() {
var $this = $(this);
$this.toggleClass('show');
if ($this.hasClass('show')) {
$this.text('Show');
} else {
$this.text('Hide');
}
});

Following your DOM tree
$('.collapse-classes').click(function() {
var span = $(this).find('span');
if(span.text() == "Show"){
span.text("Hide");
} else {
span.text("Show");
}
});
