I've been attempting to grab text input from HTML and trying to output the text back into HTML but for some reason it does not seem to be working. Does putting input within a form alter the interaction with getElementById or is it possible that the second button usage of formaction is interrupting this?
$(document).ready(function(){
$("#submit").on("click",function(){
var test = document.getElementById("searchInput");
$("#text").html(test);
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type ="text" id ="searchInput"><br>
<button id = "submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
</form>
<div id = "text">
<h1>test</h1>
</div>
EDIT: I have attempted to change
var test = document.getElementById("searchInput");
to
var test = document.getElementById("searchInput").value;
previously and it is still not working. Is there an interaction that is failing that I am missing? Also I would like to be able to store the input as variable i.e thats why I am purposely putting it into a variable before outputting it.
EDIT2: There wasn't anything particularly wrong about the code other than retrieving the value. I am currently using codepen.io to code and did not load jquery into the pen.
Since you're using jQuery, it will make more sense to use jQuery to obtain the elements' value:
Use this to always replace #text element contents with #searchInput value:
$("#text").html($("#searchInput").val());
Use this to append #searchInput value to #text element:
$("#text").append($("#searchInput").val());
But the whole logic does not make any sense. You are changing an elements' value that it is outside the form you are submitting. Either you should prevent submit button click event from submitting the form, or have the #text element inside the form as an input, textarea or hidden field:
$(document).ready(function(){
$("#submit").on("click",function(e) {
e.preventDefault();
$("#text").html($("#searchInput").val());
})
});
or having the #text element inside the form for submitting:
<form>
<input type="hidden" id="text" name="text">
<input type ="text" id ="searchInput"><br>
<button id = "submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
</form>
You Using form element, so once you click the button , the form will be reloaded, if you want to display textbox value to the element , once remove the form element.
<input type ="text" id ="searchInput"><br>
<button id = "submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
<div id ="text">
<h1 id="welc"></h1>
</div>
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.1.1.min.js" type="text/javascript"></script>
<script>
$(document).ready(function(){
$("#submit").on("click",function(){
var test = $('#searchInput').val();
$("h1").html(test);
});
});
</script>
Just Remove tag, and check it.
You need to find the element's value and then set it as HTML.
$("#text").html(test.value);
I have updated your question mate check this one .
$(document).ready(function(){
$("#submit").on("click",function(){
var test = document.getElementById("searchInput").value;
$("#text").html(test);
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type ="text" id ="searchInput"><br>
<button id = "submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
</form>
<div id = "text">
<h1>test</h1>
</div>
I think this will work for you.
<! doctype HTML>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
<form>
<input type="text" id="searchInput">
<br>
<button type="button" id="submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
</form>
<div id="text">
<h1>test</h1>
</div>
</body>
<script>
$(document).ready(function () {
$("#submit").on("click", function () {
$("#text").html($("#searchInput").val());
})
});
</script>
</html>
Edit your JS code please try:
EDIT:
$(document).ready(function(){
$("#submit").on("click",function(){
var test = $("#searchInput").val();
$("#text").html(test);
})
});

I want to do this by typing my name in the input, then pressing the button and an h1 tag will appear below the input: Hello (my name)! I don't know how to solve this.
Here is my html and jQuery code:
<form>
<label for="Name">Name</label>
<input type="text" id="Name">
<button id="button" type="button">Click</button>
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$('#button').click(function () {
$('body').append('<h1></h1>')
$("h1").append('Hello')//+ my name
})
</script>
You need to get the value from the #Name input. Unless you have a specific reason for doing this in multiple steps, you can append the html as a whole like this:
<form>
<label for="Name">Name</label>
<input type="text" id="Name">
<button id="button" type="button">Click</button>
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$('#button').click(function () {
if ($('#Name').val()) { //make sure the user entered something
$('body').append(`<h1>Hello ${$('#Name').val()}!</h1>`);
}
});
</script>
The backticks `` are a template literal, they allow you to build strings without a bunch of concatenation.
`Hello ${my_name}!` vs 'Hello ' + my_name + '!'
To get the value of the input field you can use:
$('input#Name').val();
Instead of appending it to the h1 element, you can simply set its text to the wanted value, in your case: .text('hello '+getName).
In case a visitor makes a mistake you only need to modify the inner text of the h1 instead of appending it to the body again.
$('h1').text();
$('#button').click(function () {
let getName = $('input#Name').val();
if(!$('h1').length){
$('body').append('<h1 class="greeting-title"></h1>');
}
$("h1").text('Hello '+getName)//+ my name
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form>
<label for="Name">Name</label>
<input type="text" id="Name">
<button id="button" type="button">Click</button>
</form>
IM trying to test to see if my code is set up right to access the text value of a form. im just trying to access text value and then use Console.log to confirm that its getting that far.
here is my code(
<body>
<form id="form">
<input type="text" id="item">
<button class="Btn add item">Add item</button>
</form>
<script type="text/javascript">
document.getElementById("item").onclick = function() {
var output = document.getElementById("item").value;
console.log(output);
}
</script>
</body>
When I run it in the Dev tools in chrome nothing happens. No error and console doesn't log the value I entered into the form.
You can try something like this:
var output = document.getElementById("item").innerText;
Your mistake is incorrect names of the ID-attributes. Be careful!
<body>
<form id="form">
<input type="text" id="input"/>
<button id="button" type="button">Add item</button>
</form>
</body>
<script type="text/javascript">
document.getElementById("button").onclick = function(){
var str = document.getElementById("input").value;
console.log("Your string is: " + str);
}
</script>
Your input tag lacks the value attribute and has no default value.
I'm assuming you want to log the value when the button is clicked rather than the input. Try this out:
<form id="form">
<input type="text" id="item"/>
<button id="btn" class="Btn add item" type="button">Add item</button>
</form>
<script type="text/javascript">
document.getElementById("btn").onclick = function() {
var output = document.getElementById("item").value;
console.log(output);
}
</script>
It's hard to understand what you are looking for from your example, but if you want your value to be logged as you type it can be done this way :
<form id="form">
<input type="text" id="item">
<button class="Btn add item">Add item</button>
</form>
<script type="text/javascript">
document.getElementById('item').addEventListener('keyup', function(e){
var output = e.target.value
console.log(output)
})
</script>
As Markus Zeller said, when your input tag has no value, console.log will show a space.
Try entering any number of characters, then out focus, then click on the input again, you will see it displays exactly the value of the input tag you just entered.
I'm trying to change the contents of an input tag using a JS function but nothing I tried seems to work. Here's what I tried:
function go (){
document.getElementById("input").innerHTML.value = 5;
};
<body>
<input type="number" id="input">
<button onclick="go()">go</button>
</body>
Would really appreaciate it if someone show me how this is done
just use document.getElementById("input").value
function go (){
document.getElementById("input").value = 5;
};
<body>
<input type="number" id="input">
<button onclick="go()">go</button>
</body>
You don't want to change the innerHTML, just the value of the input element (which is an attribute). So this should work. I changed to a string because that's what attributes usually are, but it shouldn't matter.
document.getElementById("input").value = "5";
How can I get the value of the textbox?
<input class="num1" type="text" val=""><br>
<button class="show">Click</button>
this is my Js code:
var value = $('.num1').text();
$('.Click').click(function(){
$('<'p>').text(value);
});
when I clicked the "click" button I want to show in a paragraph the text that I'd input to the textbox.
Use .val() for form elements to retrieve or set its value. Also, care with typo when you set the paragraph text.
var value = $('.num1').val();
$('.show').on('click', function(){
$('p').text(value);
});
In your code there is an error: if you want to catch the click event you should use the class of the button. Another error in your code is about the single quotes you use to insert value into the <p>. And remember, is $('p'), not $('<p>').
The code should look like that:
$('.show').click(function(){
$('p').text(value);
});
You can use this code:
jQuery
$(function(){
$("form").on("submit", function(event){
event.preventDefault();
var text = $(".num1").val();
$("#outputText").text(text);
})
});
Your HTML should be something like that:
HTML
<form>
<input class="num1" type="text" val="">
<button class="show">Click</button>
</form>
<p id="outputText"></p>
Note that in this case is really important to stop the default event behavior using preventDefault().
If you are not using a form the previous code became something like that:
jQuery
$(function(){
$(".show").on("click", function(event){
var text = $(".num1").val();
$("#outputText").text(text);
})
});
HTML
<input class="num1" type="text" val="">
<button class="show">Click</button>
<p id="outputText">
</p>
The outputText div is a div I've created to show the text.
I've prepared jsfiddle1, jsfiddle2 you can use to see the code in action, I hope it helps ;-)
That would be
var value = $('.num1').val();
Use the val() operator on the input to get the value, and then you could use the following code:
Html:
<input class="num1" type="text">
<button class="show">Click</button>
<p class="output"></p>
Javascript:
$('button').click(function(){
$('.output').html($('.num1').val());
});
use .val() not .text()
$(".show").click(function(){
var value= $(".num1").val();
$(".para").text(value)
});
demo
$('.show').click(function () {
var value = $('.num1').val();
$('p').text(value);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input class="num1" type="text" val=""></input>
<button class="show">Click</button>
<p></p>
There are type mistakes
var value = $('.num1').val(); should be in click method.
Use val() instead of .text() to get the input value.
Adding the insertion of input type text into the div title on the same screen. Attempted broken function to they turn the input into a variable and use it to fill in the div.
<body>
<div class="form">
Form <br><br>
<form name="input" action="javascript:alert(titleValue);">
Title: <input type="text" name="title" class="titleInsert">
<input type="submit" value="Submit">
</form>
</div>
<div class="offer_display">
<div class="title" id= title></div>
</div>
</body>
<script>
var titleValue="";
$('#titleInsert').on("change", function () {
titleValue=$(this).val();
$("#title h3").text("titleValue");
});
</script>
</html>
Another problem with you code is, that you have to use "input" event and not "change".
See working code on fiddle: http://jsfiddle.net/z037qv3n/
<body>
Form <br><br>
<form name="input" action="javascript:alert(titleValue);">
Title: <input type="text" name="title" id="titleInsert">
<input type="submit" value="Submit">
</form>
<div class="title" id="title"></div>
</body>
<script>
var titleValue="";
$('#titleInsert').on("input", function () {
titleValue=$(this).val();
$("#title").text(titleValue);
});
</script>
</html>
Change your code for $('div.title').html(titleValue);
Live Demo : JSFIDDLE
You have to include jQuery library in your head section like this
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
There are lot of mistakes in your code please see below:
First mistake you should put your jQuery inside ready function.
Second mistake there is no such id #titleInsert it is a class so you have to do .titleInsert
Third mistake there is no tag h3 in #title
Fourth mistake you should use .keyup event instead .change event
Replace your jQuery code with following :
<script type="text/javascript">
$(document).ready(function(){
var titleValue="";
$('.titleInsert').on("keyup", function () {
titleValue=$(this).val();
$("#title").text("titleValue");
});
});
</script>
