Can i update a textarea field with custom text and text from a text field?
For example:
i have a form with text field and textarea.. when i enter "Samsung" in text field, textarea field will show this: I want a Samsung phone. For LG will show I want a LG phone.
Is this posible?
Thanks!
One very simple way using javascript :
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function update(elem) {
document.getElementById('textareaDescription').value = " I want a " + elem.value + " phone";
}
</script>
</head>
<body>
Phone : <input type="text" onchange="update(this)">
<br>
Description : <textarea name="" id="textareaDescription" cols="30" rows="10"></textarea>
</body>
</html>
Using the onchange event, the textarea will be updated once you lose focus (and changed!) the input.

I am working on a spring mvc project and I have a problem. What I want is that, when the user clicks submit, we should not leave the page, we should just stay. But the values submitted would be used as a parameter to a function in the same page. Here, let's just say I want to print it, and that is the part that is wrongly entered.
What should I do to accomplish this? Please help
You can use ajax here when your submit button is clicked call this function and then using this call your ajax passed the value from your input to your server and then at your server side perform operation which you needed to do and then the result back to ajax .
Your form :
<form name="testForm" action="move.jsp">
<label><h1>Enter the data <h1/></label><br/>
<input type="text" name="DATA"><br/>
<input type="button" onclick="submit_values()">
<!--^^added this-->
</form>
<div id="result"><!--here data will come back--></div>
Then on click of your button submit_values() function will get called . i.e :
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"> </script>
<script>
function submit_values() {
//get input value
var values = $("input[name='DATA']").val();
console.log(values);
$.ajax({
type: 'POST',
data: {
values: values//passing to server
},
url: "Your_server_url",
success: function(data) {
alert(data);//this will display whatever server will return
$("#result").html(data);//add response back to show
}
});
}
</script>
Then at your server-side do like below :
String data =request.getParameter("values");//get value
String send_back = something(data);//call your function
out.println("DATA BACK"+send_back );//this will go back to ajax
I'm trying to display a message that appears after the user has input some details into input boxes. Once they put in the info in the input boxes, the page should add the info to the multi-line text and then display the entire message on the webpage with the new info included. This code I have only displays the message without the input.
Here, I'm simply having the user put in the text in the box, then I tried to "parse" the input's value by giving it a variable name with a value within the code so it can be added as a property to the "libs" object. I have more to the message, but I can't even get this one sentence to process correctly.
<!DOCTYPE html>
<html>
<head>
<title>Madder Libs</title>
</head>
<body>
<div id="input">
<form>
<p>
<h4>Piece of clothing:</h4><input id="cloth" type="text" value=" " />
</p>
</form>
</div>
<script>
let clothes = document.getElementById('cloth').value;
let libs = {
a: clothes,
/*b: firstBodyPart,
c: secondBodyPart,
d: verbOne,
e: thirdBodyPart,
f: verbTwo,
g: firstNoun,
h: secondNoun,
i: verbThree,*/
};
let showThis = function()
{
let display = function(message)
{
let sayThis = `I wear a ${message.a} on sundays.`;
return sayThis;
}
document.getElementById('madlibs').innerHTML += "<br/>" + display(libs);
}
</script>
<div id="madlibs">
<button type="submit" onclick="showThis()">Show Message</button>
</div>
</body>
</html>
I want my message to be displayed including whatever the user put in the text box
Let's start by addressing why your sentence does not work. It is simply a matter of timing or in other words when things get executed. In your code (which isn't very well structured but onto that later) you execute
let clothes = document.getElementById('cloth').value;
at the very beginning of the script. In this case you are not obtaining some form of reference that would allow you to read the value at later stage but the actual value at the time. Since your input field has value attribute set to empty string, this is all you will ever get no matter how many times you execute the function later.
In order to get value of the input at the time of calling your method you would have to move it into the function itself.
But as I mentioned earlier your code is overall structured poorly so allow me to provide a few suggestions.
button of type submit by default executes submission of the form if placed within the form; you are not taking advantage of that (this has benefits such ability to submit form with "Enter" key e.g.
placing <script> in the middle of your document is poor choice as it blocks rendering of the rest of the document. Best options are to place it either within <head> when used with defer attribute or at the end of the document just before closing </body> tag.
Nesting your function within each other has not benefit here. You can easily define them independently and call one within the other if needed.
heading element <h4> cannot appear within <p> tag
Example
<!DOCTYPE html>
<html>
<head>
<title>Madder Libs</title>
</head>
<body>
<form action="/" onsubmit="return showThis()">
<div>
<label for="cloth">Piece of clothing:</label>
<input id="cloth" type="text" value="" />
</div>
<div id="madlibs"></div>
<div>
<button type="submit">Show Message</button>
</div>
</form>
<script>
// let's get references to our elements, so we don't have to
// do it multiple times
let clothes = document.getElementById('cloth');
let madlibs = document.getElementById('madlibs');
// let's define our functions
function display(message) {
let sayThis = `I wear a ${message.a} on sundays.`;
return sayThis;
}
function showThis() {
const clothesValue = clothes.value;
let libs = {
a: clothesValue,
/*b: firstBodyPart,
c: secondBodyPart,
d: verbOne,
e: thirdBodyPart,
f: verbTwo,
g: firstNoun,
h: secondNoun,
i: verbThree,*/
};
madlibs.innerHTML += "<br/>" + display(libs);
return false;
}
</script>

I've met a weird behavior. I'm trying to get / set the value of an input textbox After FeatherLight lightbox is closed. I get "Undefined" when trying to fetch the value of the textbox (again, after it was opened and closed via Featherlight). You can see my source code here:
https://jsfiddle.net/hgyba4dg/
The only relevant part is the html code. try running the code on JSFiddle and see the input's value (the textbox's value). You'll see that you'll get "undefined" after closing the Featherlightbox. Here is the html:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript">
var storeData = null;
function openFeatherLight()
{
if (!storeData)
{
storeData = $.featherlight($('#MyDiv'), { 'persist' : true , 'beforeOpen' : sayHi , 'beforeClose' : sayBye, 'afterClose' : changeInputValueAfterClose });
}
else
{
storeData.open();
}
}
function sayHi()
{
alert('Value of textbox BEFORE opening FeatherLight LightBox Is: ' + $('#MyTextBox').val());
}
function sayBye()
{
alert('Value of textbox BEFORE CLOSING the FeatherLight LightBox Is: ' + $('#MyTextBox').val());
}
function changeInputValueAfterClose()
{
$('#MyTextBox').val("Bla");
alert('Current Value Of Input TextBox After Change is: ' + $('#MyTextBox').val());
alert('We get "Undefined". Why?');
}
</script>
</head>
<body>
<div id="Shit" style="display: none;">
<div id="MyDiv">
Text
<form id="MyForm">
<input type="text" value="Initial_Value_Set_By_Me_For_Testings" id="MyTextBox">
</form>
</div>
</div>
<input name="Button1" type="button" value="Open FeatherLight" class="AddToMenuButton" onclick="openFeatherLight();">
</body>
</html>
After the first time, the DOM elements remain detached (I open to reinsert it one day...). So $('#MyTextBox') won't work afterwards. Either keep a reference to it, or use storeData.$content.find('#MyTextBox')
What's the easiest way to get a visitors city, state and country based on their IP address and fill it into a form field?
For example I have a basic form field:
<input type="text" name="city" value="*AUTOFILL CITY HERE*" />
Instead of having them fill this information in I'd like to just hide the form field and have it autofill based on their IP.
I found a solution for you which is in the form of html, javascript and jquery.
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
</head>
<body>
<h3>Client side IP geolocation using ipinfo.io</h3>
<hr/>
<div id="ip"></div>
<div id="address"></div>
<hr/>Full response: <pre id="details"></pre>
<input type="text" value="" id="city" />
<script type="text/javascript">
$.get("https://ipinfo.io", function (response) {
$("#ip").html("IP: " + response.ip);
$("#address").html("Location: " + response.city + ", " + response.region);
$("#details").html(JSON.stringify(response, null, 4));
$("#city").html(response.city);
document.getElementById('city').value = response.city;
}, "jsonp");
</script>
</body>
</html>
City is filled in automatically, and using the same process you can display the State, as well as the Country, of your visitors.
I would like to create a popup form which will ask a user if he/she agrees with the terms and condition and has a post and cancel button. How could I create one? Could you give me an example. Thank you.
<html>
<head>
<script type="text/javascript">
<!--
function confirmation() {
var answer = confirm("Leave tizag.com?")
if (answer){
alert("Bye bye!")
window.location = "http://www.google.com/";
}
else{
alert("Thanks for sticking around!")
}
}
//-->
</script>
</head>
<body>
<form>
<input type="button" onclick="confirmation()" value="Leave Tizag.com">
</form>
</body>
</html>
Taken from TizTag...or you could use jQuery Dialog :)
