Navigating back to Search Page with same state (JavaScript)

How do I, using JavaScript, retain the state of the search page, when a user clicks into a search result, but then goes back to the main search page.
e.g.
HTML:
https://startech-enterprises.github.io/docs/guides/data-analytics/data-analytics.html
There are 5 elements that determine what is shown on the page:
What tags are clicked in the three filter menus, on the side
What search term is typed into the search menu bar, at the top
The pagination page that is selected, at the bottom
Problem is that whenever I go into the search result, and navigate back to the main search page, the search page resets itself, so I have to re-enter the search criteria again - which can be quite annoying.
If I click 'back' in the browser, the search page state is retained, but the search script stops working. Also, using the 'browser' back button only goes back one 'link' - so if the user clicks on several links in any page (returned from the search), they have to press the 'back' button many times, to get back to the main search page - which again isn't ideal.
Any ideas on how to solve this? Would seem like a fairly common problem?

Pls do help!
Many thanks in advance.

UPDATE: This has now been solved based on the answers given below

You can simply do it by saving the data in users device . You can do it by using cookies or by localStorage. I prefer localStorage because users can deny cookies easily.
Like this-
localStorage.setItem("tags",tagItemsInAnArray);
And laterlocalStorage.getItem("tags");

You can use localStorage to keep the search filter data. The concept is to keep all filter data in an array and keep that array in the localStorage of the browser before any redirection. Here is an official documentation with implementation of localStorage.
Here is a demo:
//before redirection
let filterData = [];
localStorage.setItem("searchFilter", JSON.stringify(filterData));
//after page-load
let cachedFilterData= JSON.parse(localStorage.getItem("searchFilter"));
if(cachedFilterData.length>0){
//cache data exist
}
//when you need to delete cache
localStorage.removeItem("searchFilter");

Using client side scripting to control an SAPUI5 app

So, we have an existing app, which I think is built on sapui5 if I am not mistaken. It's pretty much a simple search function app. I reviewed the DOM and noted that the search box form has the ID of #__xmlview0--searchField-F, and the search box container including all is under #__xmlview0--searchField and the actual text entry area is under #__xmlview0--searchField-I. Essentially, it looks something like this - highly simplified:
<div id = "__xmlview0--searchField">
<form id = "__xmlview0--searchField-F">
<input type = "search" id = "__xmlview0--searchField-I" />
<div id = "__xmlview0--searchField-search"></div>
</form>
</div>
There are two pages that I am interested in, one is the original start page for searching, and the other is the search page with results displayed, which also contains the same search box so that users can quickly perform another search. Lets call these start page and results page.
Since the app doesn't seem to take any QS for search strings, I was wanting to create a nested page where I can simply pass on the elements of searching into the app generated page, and display search results with one click, instead of having the users need to do them manually and transcribe things from one place to the search function.
I have attempted initially to simply change the value of the search box and then submit the search:
$("#__xmlview0--searchField-I").val("SOMETHING");
$("#__xmlview0--searchField-F").submit();
Such approach did not work. It appears that the submit will execute for the start page, but will not for the results page. But even with the start page where submit executed, the search text of "SOMETHING" has been lost for sure somehow. So I tried typing in text manually and only doing:
$("#__xmlview0--searchField-F").submit();
Which seems to show the submit button working (also only for start page, not for results page), though it appears that "SOMETHING" is still lost somehow even though I manually entered the text when executed in start page. Thinking something may be wrong with clicking the submit mechanism programatically, I tried only doing:
$("#__xmlview0--searchField-I").val("SOMETHING");
and then manually click the search execution icon (also tried pressing "enter"). But to my dismay, despite the DOM display the changes for the input search field properly, the search did not execute though the button blinked so I am sure I properly clicked it at least.
So I thought, maybe I need to trigger some kind of event before I start making changes to the search field to prompt proper event execution behind the scenes so that the input text will be recognized properly when changed:
$("#__xmlview0--searchField-I").focus();
$("#__xmlview0--searchField-I").val("SOMETHING");
$("#__xmlview0--searchField-I").focus();
$("#__xmlview0--searchField-F").submit();
But that did not work either. I am pulling my hairs out trying to figure out what may be going on. Can someone who knows the SAPUI5 stuff give me some insight? Am I doing something that is simply not possible under this environment?

how do i display user input on the same page, with the option to delete

Good day programmers. I am very new to jsp/javascript but this site has helped me a lot so far, but i can use some more help or guidance for a problem i am having.
I am making a web app for creating and saving recipes. For my "add recipe" process, i have the user enter a recipe name, they are then directed to another page where they can choose an ingredient from a dropdown (populated from a sql db), enter a quantity, and then click a button to ad another ingredient.
What i wish to do is have the ingredient selected and the amount displayed to the user on the same page where they are choosing the ingredients. I also want to add a button at the end of the "print out" that allows the user to remove that ingredient.
So far i am thinking that i should use a table and have a row created when the user adds an ingredient, then use the deleterow() method to remove that ingredient if desired.
Does anyone think this can work? or have a better solution.
PS: i am very new to jsp and javascript.
thanks in advance for any assistance rendered.

You can use ajax to achieve this. For that using jQuery will make you writing a lot less number of lines of code.
So it will work like this, they have entered the recipe name. Now using onblur on that field input, you load the dropdown of ingredients and give them option of entering quantity and selecting the ingredient with a button to save that data.
When they click on the button to save, after it getting saving into the database, you make an ajax call to load the recent added item with a button to delete it and when they click on delete, you make another ajax call to the database to delete it.
Here is a guide to ajax on javaScript

ICD 10 dropdown for a Spring application with mysql database in the background

I am currently working on a Spring healthcare application where the doctor can enter the diagnosis codes in the input tag of a page. What I want is that the doctor should be able to select the codes from a drop-down menu, the problem with ICD10 codes records is that there are a lot of them. Can anyone suggest a tool or a javascript library that can make my life easier?

You can use a search feature for this. You could have a text input with a search button. When the user types some of the initial text of the ICD-10 code and clicks the search, you perform a search request to the backend, and with the results, you can load a regular select.
Of course you would have to create a search endpoint in your backend, and possibly your select would need to be paginated. You could even display the results in a table instead of a select and add a select button to the rows.
If you just want to display the codes in your HTML, the resulting page will be heavy, no matter how many pagination features you add. If all your ICD-10 codes are sent to the client right away, we could be talking about MBs to render your page, that's why I'll move the retrieval of codes to the backend and limit it there with some "limit + offset" feature.
So, a search box. When the user clicks the search button, you perform a request telling the backend the term to search, a limit, like 10, and an initial offset, probably 0. You display those results in a table and, if there are more, a pagination. When the user clicks another page, you perform the same request specifying a different offset, and so on.

How to ultimately disable a button with javascript?

I want to build an interactive page within a website. On this page i want to put a list of items, that people can choose from, in order to bring one of them to a certain event/party.
Once a user choses an item via a confirm pop up box, i want the button to be ultimately disabled, even if the user opens the page again or another user opens the page.
I want this event to happen within a conditional statement in JavaScript somewhat like this:
if (confirm("Do you really want to bring this item to the event/party?") == true) {
HERE I WANT TO PUT THE CODE THAT IS NECESSARY!
} else {
}

I don't think you can do this with pure JavaScript, because JavaScripts loads everytime the page gets refreshed. Are you getting your data from a database? If so, you could add another field to your table e.g. "party" with the name "active". If the user clicks on a button, the party would be inactive and not showing up anymore.
But as I said, I think it's not possible with only JavaScript.
PS: Greetings from Germany ;)

You can't do this with JavaScript alone. You will need to employ some server-side scripting and (ideally) a database to store who has selected what so that you can "prevent" someone else from selecting the same item.
Your system should also include a user registration process so that you can tie your products to events and then tie users to the products they have selected for the event.
Thus:
User registers -> they select an event -> they select a currently available product -> some confirmation occurs which then flags the database that anyone else is unable to select this product for the chosen event. The confirmation can be achieved with standard forms processing methods or AJAX...

Once a user choses an item via a confirm pop up box, i want the button to be ultimately disabled, even if the user opens the page again or another user opens the page.
Javascript can't preserve these types of states. It only runs in users browsers. You can't save it to cookie either. Saved cookie is only useful for certain users certain browser. You have to save this data in your server (preferably in database) from where you can read this item is chose by a user. And then you can decide from client when to disable the button.
