How to fix Form action with method get

I have a small issues with my code.
Basically, I have a form in my index.html file:
The form from page 1 is the following:
<form method="get" name="basicSearch" id = "basicSearch" action="page2.html">
<input name="location" type="text" class="BasicSearch" id="searchInput" placeholder="Location">
<button type= "submit" class="BasicSearch" id="searchBtn" placeholder="Search"></button>
</form>
For this form, I want to use OpenWeatherMap API in order to get some weather data. My problem is the following:
I want to get what the user inputs in the form, which I think I can get by using, for example:
var searchInput = document.getElementById("searchInput");
In this variable I can store the location.
And this variable, I want to append to the link that does fetch the data from the API, in the javascript code.
When the user inputs, for example: New York, and press Search, the form action should redirect him to page2.html, where there I can show the weather data.
How can I show that weather data in the page2, with the location input from page1? I tried many times but no luck.
Some Javascript code down below:
let units = 'metric';
let searchMethod = 'q';
let searchButton = document.getElementById("searchBtn");
let searchInput = document.getElementById("searchInput");
if (searchButton) {
searchButton.addEventListener('click', () => {
let searchTerm = searchInput.value;
if (searchTerm)
searchWeather(searchTerm);
});
}
function searchWeather(searchTerm) {
fetch(`http://api.openweathermap.org/data/2.5/weather?${searchMethod}=${searchTerm}&APPID=${appId}&units=${units}`).then(result => {
return result.json();
}).then(result => {
init(result);
})
}
function init(resultFromServer){
let weatherDescriptionHeader = document.getElementById('weatherDescriptionHeader');
let temperatureElement = document.getElementById('temperature');
let humidityElement = document.getElementById('humidity');
let windSpeedElement = document.getElementById('windSpeed');
let cityHeader = document.getElementById('cityHeader');
let weatherIcon = document.getElementById('documentIconImg');
weatherIcon.src = 'http://openweathermap.org/img/w/' + resultFromServer.weather[0].icon + '.png';
let resultDescription = resultFromServer.weather[0].description;
weatherDescriptionHeader.innerText = resultDescription.charAt(0).toUpperCase() + resultDescription.slice(1);
temperatureElement.innerHTML = Math.floor(resultFromServer.main.temp) + '&#176' + " C";
windSpeedElement.innerHTML = 'Winds at ' + Math.floor(resultFromServer.wind.speed) + ' mph';
cityHeader.innerHTML = resultFromServer.name;
humidityElement.innerHTML = 'Humidity levels at ' + resultFromServer.main.humidity + '%';
}
That is some javascript code which should get the weather data.
Then, in page2, I have the following in HTML:
<div id = "weatherContainer">
<div id = "weatherDescription">
<h1 id = "cityHeader"></h1>
<div id= "weatherMain">
<div id = "temperature"></div>
<div id = "weatherDescriptionHeader"></div>
<div><img id = "documentIconImg"></div>
</div>
<hr>
<div id = "windSpeed" class = "bottom-details"></div>
<div id = "humidity" class = "bottom-details">></div>
</div>
</div>
I expected to have the weather data in page2, where the divs are.
Can somebody give me an advice, please?
Thank you!

Since the form in page1 doesn't exist in page 2, remove
let searchButton = document.getElementById("searchBtn");
let searchInput = document.getElementById("searchInput");
if (searchButton) {
searchButton.addEventListener('click', () => {
let searchTerm = searchInput.value;
if (searchTerm)
searchWeather(searchTerm);
});
}
instead put
ley searchTerm = new URLSearchParams(location.search).get('location');
searchWeather(searchTerm);
Explanation
When the page 1 form is submitted, it will load page2 like
page2.html?location=xxxx
where xxxx is the value of the <input name='location' ...
location.search will be ?location=xxxx
URLSearchParams makes dealing with these (when you have more than one especially) easier than the old method of splitting/decoding/jumping through hoops

We can simply just submit the form and get the current form input from url on page2.html
<form method="get" name="basicSearch" id = "basicSearch" action="page2.html">
<input name="location" type="text" class="BasicSearch" id="searchInput" placeholder="Location">
<button type= "submit" class="BasicSearch" id="searchBtn" placeholder="Search">Search</button>
</form>
And on the load of page2.html (before your ajax call), we can get the 'searchInput' (location) from URL by following:
<script>
let params = (new URL(document.location)).searchParams;
var searchInput= params.get('location');
</script>
Now, we can use 'searchInput' param for your api call and fetch the result.

Storage and show multiple outputs

I have a simple text input where users type anything and after sumbitting text appear on a page and stays there, which I done with localStorage, but after refreshing the page only last typed input is showing, Ill post my code to be more specific:
HTML:
<body>
<input id="NewPostField" type="text" value="">
<button onclick="myFunction()">Post</button>
<div id="Posts"></div>
</body>
JavaScript:
function myFunction() {
var NewPostField =
document.getElementById("NewPostField");
var newPost = document.createElement("p");
localStorage.setItem('text',
NewPostField.value);
newPost.innerHTML = NewPostField.value;
var Posts = document.getElementById("Posts");
Posts.appendChild(newPost);
}
(function() {
const previousText = localStorage.getItem('text');
if (previousText) {
var NewPostField = document.getElementById("NewPostField");
NewPostField.value = previousText;
myFunction();
}
})();
Any help will be great!

It seems that your code is only storing the last value posted.
To store more than one post, one idea is to stringify an array of values to store in localStorage.
Then, parse that stringified value back into an array as needed.
Here's an example:
function getExistingPosts() {
// fetch existing data from localStorage
var existingPosts = localStorage.getItem('text');
try {
// try to parse it
existingPosts = JSON.parse(existingPosts);
} catch (e) {}
// return parsed data or an empty array
return existingPosts || [];
}
function displayPost(post) {
// display a post
var new_post = document.createElement("p");
new_post.innerHTML = post;
posts.appendChild(new_post);
}
function displayExistingPosts() {
// display all existing posts
var existingPosts = getExistingPosts();
posts.innerHTML = '';
inputPost.value = '';
if (existingPosts.length > 0) {
existingPosts.forEach(function(v) {
displayPost(v);
});
inputPost.value = existingPosts.slice(-1)[0];
}
}
function addPost(post) {
// add a post
var existing = getExistingPosts();
existing.push(post);
localStorage.setItem('text', JSON.stringify(existing));
displayPost(post);
}
function clearPosts() {
// clear all posts
localStorage.removeItem('text');
displayExistingPosts();
}
var posts = document.getElementById("posts");
var inputPost = document.getElementById("input_post");
var btnPost = document.getElementById('btn_post');
var btnClear = document.getElementById('btn_clear');
btnPost.addEventListener('click', function() {
addPost(inputPost.value)
});
btnClear.addEventListener('click', clearPosts);
displayExistingPosts();
<input id="input_post" type="text" value="">
<button type="button" id="btn_post">Post</button>
<button type="button" id="btn_clear">Clear</button>
<div id="posts"></div>
Since localStorage isn't supported in StackSnippets, here's a JSFiddle to help demonstrate.

Append localstorage data to the body element on All session (Works also with reload)

I have some code from input, and I wanna to save it to some body element.
I can add it to the body, but it disappear when page is reloaded
function store(){
var nameOfbook = document.getElementById("nameOfbook");
var value = localStorage.setItem("nameOfbook", nameOfbook.value);
var storedValueBockName = localStorage.getItem("nameOfbook");
var par = document.createElement('P');
par.innerText = storedValueBockName;
document.body.appendChild(par);
}
<form action="\" class="form-login" method="post" />
<input name="text" type="text" id="nameOfbook" required="" placeholder="Book name" />
<button onclick="store()" type="button">StoreText</button>
</form>

This question is basically asking how to retrieve a stored value from localStorage.
So you're setting the value in localStorage, but when you reload the page, you need to have a script that checks to see if there's a value in localStorage and add that data to your page if it is found there.
I would suggest something like:
<script>
var setText = function(text) {
var par = document.createElement('P');
par.innerText = text;
document.body.appendChild(par);
}
var checkLocalStorage = function() {
var value = localStorage.getItem("nameOfbook")
if (value) {
setText(value)
}
}
checkLocalStorage()
function store(){
var nameOfbook = document.getElementById("nameOfbook");
var value = localStorage.setItem("nameOfbook", nameOfbook.value);
var storedValueBockName = localStorage.getItem("nameOfbook");
setText(storedValueBockName)
}
</script>
So I moved the code that appends the title to the page into its own function so that it can be used by both store() and checkLocalStorage(). checkLocalStorage looks to see if there's a value set for nameOfbook and, if there is, passes that value to setText.
Should do the trick.

Storing value from text field in object, Javascript

I want to update my object with values from text fields.
I think the problem is with the click eventhandler on the button but not sure. I've tried a few things, Your help would be amazing.
HTML
<form>
<label><p>Book Name: </p></label>
<input name="booktitle" id="booktitle" type="text" value="I'm a value">
<label><p>Total Pages: </p></label>
<input type="text">
<label><p>Current Page: </p></label>
<input type="text">
<button id="my-Btn" type="button">Add to List</button>
</form>
JS
(function() {
// Create book object
var book = {
name: 'JavaScript & jQuery',
totalPages: 622,
pages: 162,
pagesLeft: function() {
var total = this.totalPages - this.pages;
return total;
},
percentageLeft: function() {
var totalPercentage = this.pagesLeft() / this.totalPages * 100
return Math.round(totalPercentage);
}
};
// write out book name and pages info
var bookName, totalPages, pagesLeft, percentageLeft; //declares variables
bookName = document.getElementById('bookName'); // gets elements from document
totalPages = document.getElementById('totalPages');
pagesLeft = document.getElementById('pagesLeft');
percentageLeft = document.getElementById('percentageLeft');
bookName.textContent = book.name; // write to document
totalPages.textContent = 'Total Pages: ' + book.totalPages;
pagesLeft.textContent = book.pagesLeft();
percentageLeft.textContent = book.percentageLeft() + '%';
// pull value from text field and set to object
document.getElementById("my-Btn").addEventListener("click", function() {
book.name = document.getElementById('booktitle').value;
});
}());
Code Pen of what I have so far.

Thanks in advance.

Your code already updates an object's property (book.name) with a value from a text field (#booktitle). You can see this by adding alert(book.name); after the line
book.name = document.getElementById('booktitle').value;
As Jazcash noted, if you wanted to display the updated book name everytime it was changed, you'd need to add
bookName.textContent = book.name;
In your eventlistener, so it'd look something like this:
document.getElementById("my-Btn").addEventListener("click", function() {
book.name = document.getElementById('booktitle').value;
bookName.textContent = book.name;
});

The problem is you're setting your divs textContent based on book here: bookName.textContent = book.name;. But then you need to do it again in your event like so:
book.name = bookName.value;
bookName.textContent = book.name;
You'll need to do this for all your fields

Trigger a html button inside a web browser control

in my web browser control i am accessing a form:
<form role="form">
<div class="form-group">
<input type="text" class="form-control" id="InputEmail1" placeholder="name...">
</div>
<div class="form-group">
<input type="email" class="form-control" id="InputPassword1" placeholder="email...">
</div>
<div class="form-group">
<textarea class="form-control" rows="8" placeholder="message..."></textarea>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
How can i trigger this button automatically from vb.net application? how can i set text to the text area? am accessing the text box as follows:
WebBrowser1.Document.GetElementById("InputEmail1").SetAttribute("value", "Sample")
WebBrowser1.Document.GetElementById("InputPassword1").SetAttribute("value", "Sample")
i cannot access button and text area since it does not have an id or name? is their any possibility to do like this?

Your elements need to have IDs and if you doesn't have access to the html code you can enumerate elements like this but you must know which element is the right one:
foreach (HtmlElement element in WebBrowser1.Document.Forms[0].All)
{
if (element.TagName.ToLower() == "textarea".ToLower())
{
element.InnerText = "text";
}
}
for clicking a button try this:
element.InvokeMember("click");

In a lot of web automation, unless you can get the original devs to add ids, you have to navigate the DOM in order to find what you need.
Here is an example of doing that kind of filtering and web automation
var actionPanel = topPanel.insert_Above(40);
var ie = topPanel.add_IE_with_NavigationBar().silent(true);
var server = "http://127.0.0.1.:8080";
Action<string,string> login =
(username, password) => {
ie.open(server + "/jpetstore/shop/signonForm.do");
ie.field("username",username);
ie.field("password",password);
ie.buttons()[1].click();
};
Action loginPlaceAnOrderAndGoToCheckout =
()=>{
ie.open("http://127.0.0.1:8080/jpetstore");
ie.link("Enter the Store").click();
//login if needed
var signOffLink = ie.links().where((link)=> link.url().contains("signonForm.do")).first();
if(signOffLink.notNull())
{
signOffLink.click();
login("j2ee", "pwd1");
}
ie.links().where((link)=> link.url().contains("FISH"))[0].click();
ie.link("FI-FW-01 ").flash().click();
ie.links().where((link)=> link.url().contains("addItemToCart"))[0].flash().click();
ie.links().where((link)=> link.url().contains("checkout.do"))[0].flash().click();
ie.links().where((link)=> link.url().contains("newOrder.do"))[0].flash().click();
};
Action scrollToTotal =
()=>{
var tdElement = ie.elements().elements("TD").toList().Where((element)=> element.innerHtml().notNull() && element.innerHtml().contains("Total:")).first();
tdElement.scrollIntoView();
tdElement.injectHtml_beforeEnd("<h2><p align=right>Look at the Total value from the table above (it should be 18.50)</p><h2>");
};
Action<string> exploit_Variation_1 =
(payload) => {
loginPlaceAnOrderAndGoToCheckout();
ie.buttons()[1].flash().click();
ie.open(server + "/jpetstore/shop/newOrder.do?_finish=true&" + payload);
scrollToTotal();
};
Action<string> exploit_Variation_1_SetTotalPrice =
(totalPrice) => {
var payload = "&order.totalPrice={0}".format(totalPrice);
exploit_Variation_1(payload);
};
Another option (which I also use quite a lot) is to actually use Javascript to do those actions (which is much easier if jQuery is available (or injected) in the target page).
