I wanted to modify something in my code and don't really know how to make this work... my code is kinda huge so I am going to explain what I want with an exemple :
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="stylesheets/application.css">
</head>
<body>
<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<div id="button">OK</div>
<div id="nfa"></div>
<script src="script1.js"></script>
<script src="script2.js"></script>
<script src="script3.js"></script>
</body>
</html>
So this is my HTML code, so what I want to do is NOT execute these 3 scripts until the user enters a value in the text input and clicks on OK. That value will be used in the js files, so i have to get the value after I click OK.
Can someone explain how this has to work ?
EDIT : problem was with jQuery that was not executing on Electron, solution : http://ourcodeworld.com/articles/read/202/how-to-include-and-use-jquery-in-electron-framework
For starters I would suggest changing; <div id="button">OK</div> to <button id="button">OK</button>.
I would then suggest to put each of those scripts into functions instead, then you can use the 'onClick' event from the button attribute as follows;
<button id="button" onClick="s1Func();s2Func();s3Func();">OK</button>
A better way would be to have one function call 'init' or something appropriate that then calls the 3 scripts/functions and have your buttons onClick even call that one initialization function.
JSFiddle Example:
https://jsfiddle.net/JokerDan/h7htk9Lp/
I would recommend you to load the scripts dynamically after you click on the button. This can be done via jQuery: https://api.jquery.com/jquery.getscript/
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="stylesheets/application.css">
<title>NFA2DFA</title>
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
</head>
<body>
<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<div id="button" onclick="loadScripts();">OK</div>
<div id="nfa"></div>
<script>
function loadScripts() {
// Is the input empty?
var value = $("#reg_expr").val();
if (value.length != 0) {
// Loads and executes the scripts
console.log(value); // Displays the value of the input field
$.getScript("script1.js");
$.getScript("script2.js");
$.getScript("script3.js");
}
}
</script>
</body>
</html>
You can use a button tag instead of input tag. I suggest you to use onClick event like this:
<button type="button" onclick="yourFunction()">Click me</button>
When the users click the button yourFunction() is call.
The result is this:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="stylesheets/application.css">
<script src="script1.js"></script>
<script src="script2.js"></script>
<script src="script3.js"></script>
</head>
<body>
<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<button type="button" onclick="yourFunction()">Click me</button>
</body>
</html>

When I click The button it does not show me any output on the console window
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<button type="button" id="Click me">Click me</button>
<script type="text/javascript" src="script.js">
</body>
</html>
->js
var printNumber=document.getElementById('Click me');
printNumber=document.addEventListener('Click',showNo);
function showNo() {
console.log('I was Clicked');
}
You have a few issues with your code.
Firstly you need to close your <script> tag in your HTML:
<script type="text/javascript" src="script.js"></script>
Secondly, your id shouldn't have spaces in it. You can change it to something like btn-click:
<button type="button" id="btn-click">Click me</button>
And then make sure to target it properly in your Javascript:
var printNumber=document.getElementById('btn-click');
Thirdly, your event name should be lowercase (as Javascript is case-sensitive), so change "Click" to "click"
Lastly, you want to add the click event listener to your button, which is stored in the variable printNumber. At the moment you are adding the event listener to your document and not the button. To add it to your button you can use:
printNumber.addEventListener("click", showNo); // add click event listener to button
See working example below:
var printNumber = document.getElementById('btn-click'); // change id selector
printNumber.addEventListener('click', showNo); // change 'Click' to 'click'
function showNo() {
console.log('I was Clicked');
}
<!DOCTYPE html>
<html>
<head>
<title>Awesome button</title>
</head>
<body>
<button type="button" id="btn-click">Click me</button> <!-- change id -->
<script type="text/javascript" src="script.js"></script> <!-- close script -->
</body>
</html>
It should be click not Click!
JavaScript is a case-sensitive language. This means that the language keywords, variables, function names, and any other identifiers must always be typed with a consistent capitalization of letters.
var printNumber=document.getElementById('Click me');
printNumber=document.addEventListener('click',showNo);
function showNo() {
console.log('I was Clicked');
}
<!DOCTYPE html>
<html>
<head>

<body>
<button type="button" id="Click me">Click me</button>

You had one typo Click which is supposed to be click.
`printNumber=document.addEventListener('Click',showNo);`
^^^^^^^^
you should add event listener to that particular element not to the complete document.
var printNumber=document.getElementById('Click_me');
printNumber.addEventListener('click',showNo);
function showNo() {
console.log('I was Clicked');
}

I am currently writing a function that writes a bit of code for me based on an input. I am currently working on creating the input and the code that pastes the input, but whenever it writes, it shows up as undefined. This is the code.
<!DOCTYPE html>

<meta charset="utf-8">

<body>
<form class="yamlform" action="index.html" method="post">

<button type="submit" onclick="writeAppName()">Submit</button>
</form>
<script type="text/javascript">
var appname = document.getElementsByName("appname").value
function writeAppName() {
document.write(appname)
}
</script>
</body>
</html>
NOTE: This is not my final version of the code, at the moment I just want a system for writing an input value that I can duplicate. Final version will be using document.getElementbyID.
document.getElementsByName returns colection. Use document.getElementsByName("appname")[0].value.

You need to refer to the first element with name "appname", because it could be a collection. Also I but the assignment for appanme variable inside of the function, this will make it so appname isn't being assigned to "Name" right away and is instead assigned to whatever is in the text box when you click the botton

The problem is with your document.getElementsByName
It is possible that multiple elements would have same name.
While using document.getElementsByName, there might be multiple elements instead of a single element present in DOM with similar name, so document.getElementsByName returns an array (a list of elements) and not a single element
To use different elements of the Array, use
document.getElementsByName("appname")[0] // For first element with name
document.getElementsByName("appname")[1] // For second element with name
// and so on
So in your code, you would use
var appname = document.getElementsByName("appname")[0].value;
How to display 2 digits the last phone number when I input phone number to first text field and display automatic to second text field with AJAX or JavaScript or jQuery ?.
I want to get script about that for my website like this video.
I've searched everywhere in Google Search about that, I only found this JavaScript.
But that is not solution. Please help me to resolve solution and what should I do.
Where I can get AJAX or JavaScript or jQuery like that or are there soluton in this forum ?
In the code you found, changing
$('#output').text($('#txt').val());
to
$('#output').text($('#txt').val().substr(-2));
would be what you need
or
$('#output').value($('#txt').val().substr(-2));
if the output is an <input type="text" > element
I've combined this script from http://jsbin.com/oleto5/5/edit?html,js,output and http://jsfiddle.net/AEMLoviji/tABDr/
But there is a little problem in code : $('#numbers').val($('#tt').val()+String.fromCharCode(event.keyCode));
If I remove +String.fromCharCode(event.keyCode)); and script be replaced to .substr(-2)); does not work.
If I use +String.fromCharCode(event.keyCode)); is not perfect when I remove digits.
Example :
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>berkelilingkesemua.info</title>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/base/jquery-ui.css" rel="stylesheet" type="text/css" class="jsbin" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js" type="text/javascript" class="jsbin"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.5/jquery-ui.js" type="text/javascript" class="jsbin"></script>
</head>
<body>
<script type="text/javascript">
$(function(){
$('#txt').keydown(function(){
setTimeout(function() {
$('#output').text($('#txt').val().substr(-2));
}, 50);
});
});
</script>
<input id="txt" type="text" />
<div id="output"></div>
<hr>
Second script is combined by me from first script becomes like below.
<hr />
<script type="text/javascript">
$(document).ready(function() {
$("#tt").keydown(function (event) {
setTimeout(function() {
}, 50);
{
$('#numbers').val($('#tt').val()+String.fromCharCode(event.keyCode));
}
});
});
</script>
<input type="text" id="tt" />
<input type="text" id="numbers" />
</body>
</html>
Are there solution about this script ?.
I'm newbie to web programming and I can't understand why the following code doesn't work.
It is supposed to remove permanently the content of the div element when the button is pressed, but it disappears for a while and then reappears.
The code is the following:
<!DOCTYPE html>
<html lang="es">
<head>
</head>
<body>
<script type="text/javascript">
function prueba(){
document.getElementById('uno').innerHTML="";
}
</script>
<div id="uno">CONTENEDOR UNO</div>
<form onSubmit="prueba()">
<input type="submit" value="Entrar" >
</form>
</body>
</html>
I believe what's happening is that your button is submitting a form, which sends the form to the web server then reloads your page. So:
Your "onSubmit" JS runs immediately and clears the div content.
Your page reloads and the content comes back.
Try something like this instead of a form (i.e. remove the surrounding form tag):
<button onclick="prueba()">Entrar</button>
Try this. You don't need a form to hide a DIV
<!DOCTYPE html>
<html lang="es">
<head>
</head>
<body>
<script type="text/javascript">
function prueba(){
document.getElementById('uno').innerHTML="";
}
</script>
<div id="uno">CONTENEDOR UNO</div>
<input type="button" onclick="prueba()" value="Entrar">
</body>
</html>
DEMO : http://jsfiddle.net/36pvts4t/2/
try this , for me this is working .This code is remove the text in div with id "uno" , on form submit .
<!DOCTYPE html>
<html lang="es">
<head>
</head>
<body>
<script type="text/javascript">
function prueba(){
console.log("Inside the function preueba ");
document.getElementById('uno').innerHTML="";
}
</script>
<div id="uno">CONTENEDOR UNO</div>
<form action="#" method="get" onSubmit="prueba()" target="_blank" >
<input type="submit" value="Entrar" >
</form>
</body>
</html>
I have the following code that works:
<html>
<head>
<script>
function loaded(){
oFormElement = document.forms['test form'].elements["txtStatus"];
oFormElement.value = "just loaded";
}
</script>
</head>
<body onload="loaded()">
<p>my first socket.io test</p>
<form id = "test form">
<input type="text" id ="txtStatus" value="">
</form>
</body>
</html>
now, if I include the reference to socket.io, it stops working
<html>
<head>
<script src="socket.io/socket.io.js">
<script>
function loaded(){
is this because socket.io handles from elements in it's own way, or is because the browser cannot find socket.io ? Is there any way to debug this/fix this ?
You need to close the first <script> tag...
<html>
<head>
<script src="socket.io/socket.io.js"></script>
<script>
function loaded(){
// ...
