<html>
<script>
function getText1(){
var in1=document.getElementById('in1').value;
var in2=document.getElementById('in2').value;
var tot1=parseInt(in1)*parseInt(in2);
document.getElementById('tot1').value=tot1;
}
function getText2(){
var in1=document.getElementById('in3').value;
var in2=document.getElementById('in4').value;
var tot2=parseInt(in1)*parseInt(in2);
document.getElementById('tot2').value=tot2;
}
function gt1(){

use this code it is working. and compare with own code. thanks..
There are several problem
1). Element id is one line is incorrect. It should be:
document.getElementById('gt1').value = gt1;
2). result variable is undefined. It should be:
if (!isNaN(gt1))
3). onclick="gt1()" will not work (because there is id with the same name gt1). Use, for example:
function getText3() { ... }
and
<input type="text" onclick="getText3()" id="gt1"/>
Fiddle.
Update. Ok, I didn't notice that you want multiplication, but somewhy had written + in getText1() and getText2() functions. Then you should also replace these two + with *:
Multiplication fiddle.
You dont have element with id 'gt'.
Change last line of code to this:
document.getElementById('gt1').value = gt1;
You have not defined 'result' variable
and in 'gt1()' :
document.getElementById('gt').value = gt1;
1- There is no 'gt' element in the page
2- 'gt1' should renamed to 'result'
and at the end code will be:
<script language="javascript" type="text/javascript">
function getText1() {
var in1 = document.getElementById('in1').value;
var in2 = document.getElementById('in2').value;
var tot1 = parseInt(in1) + parseInt(in2);
document.getElementById('tot1').value = tot1;
}
function getText2() {
var in1 = document.getElementById('in3').value;
var in2 = document.getElementById('in4').value;
var tot2 = parseInt(in1) + parseInt(in2);
document.getElementById('tot2').value = tot2;
}
function gt1() {
var in1 = document.getElementById('tot1').value;
var in2 = document.getElementById('tot2').value;
var result = parseInt(in1) + parseInt(in2);
if (!isNaN(result)) {
document.getElementById('gt1').value = result;
}
//document.getElementById('gt1').value=gt1;
}
</script>
this is work properly.
Check the below code.
<script >
function getext3(){
txt1 = document.getElementById("text1").value;
txt2 = document.getElementById("text2").value;
document.getElementById("text3").value = parseInt(txt1)*parseInt(txt2);
}
function getext6(){
txt1 = document.getElementById("text4").value;
txt2 = document.getElementById("text5").value;
document.getElementById("text6").value = parseInt(txt1)*parseInt(txt2);
}
function getext7(){
txt1 = document.getElementById("text3").value;
txt2 = document.getElementById("text6").value;
document.getElementById("text7").value = parseInt(txt1)+parseInt(txt2);
}
</script>
Text1 : <input type="text" id="text1" value="5"> <br/>
Text2 : <input type="text" id="text2" value="2"> <br/>
Text3 : <input type="text" id="text3" value="" onclick="getext3()"> <br/>
Text4 : <input type="text" id="text4" value="7"> <br/>
Text5 : <input type="text" id="text5" value="10"> <br/>
Text6 : <input type="text" id="text6" value="" onclick="getext6()"> <br/>
Text7 : <input type="text" id="text7" value="" onclick="getext7()"> <br/>

I have two text type inputs. I want to convert them into one textbox(Lowercase with dash) while typing just like below.
<input type="text" name="first">
<input type="text" name="last">
I want combine this two text box into another textbox
Example: Nikhil Patel to nikhil-patel
I am trying to combine below inputs but can't.
function conv(){
var title, author;
title = document.getElementById("title").value;
author = document.getElementById("author").value;
/*converting to LowerCase*/
title = String.toLowerCase(title);
author = String.toLowerCase(author);
var out = title + "-" + author;
document.getElementById("output").value = output;
}
<div class="form-group">
<label>Title :</label>
<input class="form-control" type="text" name="title" id="title" />
</div>
<div class="form-group">
<label>Author :</label>
<input class="form-control" type="text" name="author" id="author" />
</div>
<div class="form-group">
<label>Output :</label>
<input class="form-control" type="text" name="output" id="output"/>
</div>
Output is not printing automatically
Try This if you want like this...
var input = $('[name="first"],[name="last"]'),
input1 = $('[name="first"]'),
input2 = $('[name="last"]'),
input3 = $('[name="final"]');
input.change(function () {
input3.val(input1.val() + ' - ' + input2.val());
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input type="text" name="first" id="1" value="">

this is just a sample with 3 text boxes where
first two boxes will be for input
and third will auto populate using the javascript
I hope it'll help you. All is did was to add extra id's.
I want it to read the-number-that-has-been-computed) where the-number-that-has-been-computed is the result of the addition of the first two text boxes( I am also using window.onload that is why my script is in the head of the file.
function setUpEvents() {
function add_number() {
var first_number = parseInt(document.getElementById("tb1").value);
var second_number = parseInt(document.getElementById("tb2").value);
var result = first_number + second_number;
document.getElementById("tb3").value = result;
};
}
window.onload = function() {
setUpEvents();
};
<div>
<h1>Add two number using text box as input using javascript</h1>
</div>
Enter First Number : <br>
<input type="text" id="tb1" name="TextBox1">
<br> Enter Second Number : <br>
<input type="text" id="tb2" name="TextBox2">
<br> Result : <br>
<input type="text" id="tb3" name="TextBox3">
<br>
<input type="button" name="b1" value="GO" onclick="add_number()">
Just remove the setUpEvents to not have the function out of scope for the inline event handler
Also remove the inline event handler
Use eventListeners instead. I changed the name to id for the button
function add_number() {
var first_number = parseInt(document.getElementById("tb1").value);
var second_number = parseInt(document.getElementById("tb2").value);
var result = first_number + second_number;
document.getElementById("tb3").value = "The-number-that-has-been-computed is "+ result;
};
window.addEventListener("load", function() {
document.getElementById("b1").addEventListener("click", add_number);
});
input { width: 300px }
<div>
<h1>Add two number using text box as input using javascript</h1>
</div>
Enter First Number : <br>
<input type="text" id="tb1" name="TextBox1">
<br> Enter Second Number : <br>
<input type="text" id="tb2" name="TextBox2">
<br> Result : <br>
<input type="text" id="tb3" name="TextBox3">
<br>
<input type="button" id="b1" value="GO" />
Let us say I have an HTML form, with two textboxes, I want to add the two numbers in the two textboxes and display the result in a paragraph. How can I do that?
Change paragraph according to textbox is what I can't find!
Very simple:
document.getElementById('sum').onsubmit = add;
function add(e) {
e.preventDefault();
var num1 = document.getElementById('num1').value;
var num2 = document.getElementById('num2').value;
var result = 'Result: ' + String(parseInt(num1) + parseInt(num2));
var p = document.getElementById('result');
p.innerHTML = result;
}
<form id="sum">
<label for="num1">First number:</label>
<br />
<input type="text" id="num1" />
<br />
<label for="num1">Second number:</label>
<br />
<input type="text" id="num2" />
<br />
<input type="submit" value="Add" />
</form>
<p id="result">Result:</p>
In the html we have a form with 3 inputs, 2 are type text and one is type submit. and also a paragraph.
In the javascript we assign to the form's onsumbit event the function add(), in the function we prevent the default so the form wont refresh the page, then we get the 2 values that were inputed, create a string that would contain the sum of those values and set the paragraph's innerHTML to it.
Create a calculator function and then you can fire it on keyup or you can assign it to a button if you'd like.
function calcTotal(){
var inputs = document.getElementsByTagName('input'),
result = 0;
for(var i=0;i<inputs.length;i++){
if(parseInt(inputs[i].value))
result += parseInt(inputs[i].value);
}
document.getElementById('total').innerHTML = 'Total: ' + result;
}
<form>
<input onkeyup="calcTotal()" type="text" />
<input onkeyup="calcTotal()" type="text" />
</form>
<p id="total"></p>
follow bellow JS code:
<html>
<head>
<title>Sum Two Number</title>
<script language="javascript">
function addNumbers()
{
var val1 = parseInt(document.getElementById("value1").value);
var val2 = parseInt(document.getElementById("value2").value);
if(val1 !== "" && val2 !== "") {
var result = val1 + val2;
document.getElementById('result').innerHTML = result;
}
}
</script>
</head>
<body>
value1 = <input type="text" id="value1" name="value1" value="0" onkeyup="javascript:addNumbers()"/>
value2 = <input type="text" id="value2" name="value2" value="0" onkeyup="javascript:addNumbers()"/>
<p>Answer = <span id="result"></span></p>
</body>
</html>
In this example, you have a form with 2 input. When you press on a button, the value of those 2 input is added inside a paragraph.
Hope this help.
function addInputContentToParagraph() {
var txtValue1 = document.getElementById('textbox1').value;
var txtValue2 = document.getElementById('textbox2').value;
document.getElementById('para').innerHTML = txtValue1 + ' ' + txtValue2;
}
a {
cursor:pointer;
border:1px solid #333;
padding:4px;
margin:10px;
display:inline-block;
}
<form id="myForm" name="myForm">
<input type="text" name="textbox1" id="textbox1" value="1">
<input type="text" name="textbox2" id="textbox2" value="2">
</form>
<a onclick="addInputContentToParagraph();">Add Input Values to Paragraph</a>
<p id="para"></p>
I'm new to JavaScript and I need to use the string method all in one html page. I need to make sure user input the data, but I can't get my function calling to work. Any idea? I finished all of it, but just to make sure that one button submit can validate all string method function perfectly.

This is my JavaScript code:
<script>
function validateEverything(){
var wo1 = document.getElementById("word1").value;
var wo2 = document.getElementById("word2").value;
var sub = document.getElementById("subtr").value;
var lin = document.getElementById("lastindex").value;
var sea = document.getElementById("srch").value;
var lca = document.getElementById("lcase").value;
var uca = document.getElementById("ucase").value;
var mat = document.getElementById("match").value;
var ma1 = document.getElementById("match1").value;
var phr = document.getElementById("phrase").value;
var rep = document.getElementById("replce").value;
var re1 = document.getElementById("replce1").value;
var ph1 = document.getElementById("phrase1").value;
var spl = document.getElementById("splt").value;
var cha = document.getElementById("cca").value;
var slc = document.getElementById("slce").value;
var ans = document.getElementById("answers");
//Concat
var con = wo1.concat(" "+wo2);
//Subtr
var subr = sub.substring(1, 7);
//lastindexof
var n = lin.lastIndexOf(sea);
//toLowerCase
var lc = lca.toLowerCase();
//toUpperCase
var uc = uca.toUpperCase();
//match
var mc = mat.match(ma1);
//replace
var rp = phr.replace(replce, replce1);
//split
var sp = sp1.split(" ")
//charCodeAt
var cc = cha.charCodeAt(0);
//slice
var sl = slc.slice(1, 5);
show();
}
function show(){
ans.innerHTML = answersHTML();
}
//answers
function answersHTML(){
var ans = document.getElementById("answers").innerHTML;
document.write(con);
document.write(subr);
document.write(n);
document.write(lc);
document.write(uc);
document.write(mc);
document.write(rp);
document.write(sp);
document.write(cc);
document.write(sl);
}
</script>
There are multiple issues in your snippet.In some case there is no DOM element present but still you are doing document.getElementById();
Also how answerHTML will know about con,sub,.... ? They are local to validateEverything function & you are not passing it to answerHTML function
You are using input type = "submit". You need to use event.preventDefault() to stop submission. You are not submitting anything. Rather use input type = "button"
There is also no use of show() function
Everytime you are using document.write, so it will delete anything which is previously written. Instead string concatenation and innerHTML will be fine.
Here is a working snippet with minimum code.
JS
function validateEverything(event){
event.preventDefault();
var wo1 = document.getElementById("word1").value;
var wo2 = document.getElementById("word2").value;
var sub = document.getElementById("subtr").value;
var ans = document.getElementById("answers");
//Concat
var con = wo1.concat(" "+wo2);
//Subtr
var subr = sub.substring(1, 7);
ans.innerHTML = con+" "+subr;
}
HTML
<input type="submit" value="Submit" id="btnSubmit" onclick="validateEverything(event)">
JSFIDDLE
Learning to code and having a problem creating arrays from jQuery objects. I would like to give the user the option of adding as many "Favorite Books" as they want to their profile.
The UI is written in jQuery,
<script language="javascript">
function one()
{
var i = 1;
my.innerHTML = my.innerHTML +"<br><input type='text' name='title'+i[] >"
var n = 1;
[
div.innerHTML = div.innerHTML +"<br><input type='text' name='author'+n[] >"
]
}
</script>
I have tried:
var obj = $('input');
var arr = $.makeArray(obj);
I was hoping it was actually that easy but the output is:
<div id="div">
<br>
<input type="text" +n[]="" name="author">
<br>
<input type="text" +n[]="" name="author">
<br>
<input type="text" +n[]="" name="author">
</div>
I have tried option number two which I found here yet gave me the same output:
var author = new Array();
//get all the authors
$('.auth input').each(function (i)
{
var author= $(this).val();
if(author!= '')
{
author[author] = author;
alert(author.length);
}
});
and same results. I was hoping for results like this:
<div id="div">
<br>
<input type="text" name="author[0]">
<br>
<input type="text" name="author[1]">
<br>
<input type="text" name="author[2]">
</div>
so I can parse out to a PHP array.
Maybe:
<script language="javascript">
var i = 0;
function one(){
$('#my').append("<br><input type='text' name='title["+i+"]'>");
$('#div').append("<br><input type='text' name='author["+i+"]'>");
i++;
}
</script>
