my problem is quite minor.
I do not get along with the syntax of JavaScript
What I want to do is actually cause the following code to occur:
with this regex:
^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5]).){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$

I want to open a new window on click of a button. It is opened successfully but I can't write data and set title simultaneously.
Does anybody have any idea?
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title And Data Both</title>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
var filename ="console.log";
var newwin = window.open("","","width=200,height=100");
newwin.document.title="Title";
newwin.document.write("<h1>XXXX</h1>");
});
});
</script>
</head>
<body>
<button type="button">Get Substring</button>
</body>
</html>
The document.write() overwrites all existing HTML(including the title).
One way you could do it, is to set the title after the write.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title And Data Both</title>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("button").click(function () {
var filename = "console.log";
var newwin = window.open("", "", "width=200,height=100");
newwin.document.write("<h1>XXXX</h1>");
newwin.document.title = "Title";
});
});
</script>
</head>
<body>
<button type="button">Get Substring</button>
</body>
</html>
I wanted save value in inputbox to JS variable, but when i save it, doesn't appear in console, why? thanks for advice
<!DOCTYPE html>
<html dir="ltr">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Color Picker</title>
<link href="color-picker.min.css" rel="stylesheet">
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.3.min.js" ></script>
</head>
<body>
<p><input type="text"></p>
<script src="color-picker.min.js"></script>
<script>
var picker = new CP(document.querySelector('input'));
picker.on("change", function(color) {
this.target.value = '#' + color;
})
function colorpick() {
var el = document.querySelector('input');
console.log(el);
}
</script>
<input onclick="colorpick()" type="button" class="button" value="Submit">
</body>
</html>
I am not sure what are you trying to accomplish but colorpick function is only selector of the input element itself. You need console.log(el.value) instead.
How can I pass argument to function redirect in JavaScript
Here is my code:
<script type="text/javascript">
<!--
function redirectlink(text){
window.location = "index.php?keyName="+ text;
}
//-->
</script>
<form>
<button type="button" id="butt_1" onclick="redirectlink(KEY_POWER)"> 1 </button>
Thank you in advance.
This can be done either by using getElementById and addEventListener
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<button id="foo">Click</button>
<script type="text/javascript">
document.getElementById("foo").addEventListener("click", function(){
window.location.replace("http://stackoverflow.com/q/36933820/5526354")
})
</script>
</body>
</html>
either onclick
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<button id="foo" onclick="action()">Click</button>
<script type="text/javascript">
function action(){
window.location.replace("http://stackoverflow.com/q/36933820/5526354")
}
</script>
</body>
</html>
Using onclick is deprecated.
With just only JavaScript (without jQuery / Angular etc.) you can use addEventListener on click event.
for example:
var btn = document.getElementById('butt_1');
btn.addEventListener('click', function(e) {
// your code
});
In this function you can for example get value/txt from this button element and something else which you want.
This is such a basic thing, I could not figure out. Consider the following:
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.4.js" />
<script language="JavaScript" type="text/javascript">
function Show(msg){
alert(msg);
}
</script>
</head>
<body>
<input type="button" onClick="Show('hello');" value="Show 1" />
</body>
</html>
The above sample works fine if I exclude "jquery" include. What am I missing here?
that is because self closing script tags do not work. use:
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.4.js"></script>

I am new to qunit.I am running simple testcase in qunit.but nothing is getting displayed on screen.
This is HTML Runner:-
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>QUnit Demo</title>
<link rel="stylesheet" href="//code.jquery.com/qunit/qunit-1.14.0.css">
<script src="//code.jquery.com/qunit/qunit-1.14.0.js"></script>
<script src="MyJsUnitTests.js"></script>
<script src="MyJsSourceCode.js"></script>
</head>
<body>
<div id="qunit"></div>
<div id="qunit-fixture"></div>
</body>
</html>
This is MyJsSourceCode.js
var ArthimeticOperations = {
addTwoNumbers : function (number1, number2) {
return number1 + number2;
}
}
This is MyJsUnitTests.js
test('Addition Test', function () {
strictEqual(ArthimeticOperations.addTwoNumbers(3, 5), 8, "Tested the addition functionality");
});
Try swapping the source code and test code includes... my guess is that your tests start running before the source code is included in the page:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>QUnit Demo</title>
<link rel="stylesheet" href="//code.jquery.com/qunit/qunit-1.14.0.css">
<script src="//code.jquery.com/qunit/qunit-1.14.0.js"></script>
<!-- SWAP THESE TWO...
<script src="MyJsUnitTests.js"></script>
<script src="MyJsSourceCode.js"></script>
Like so:
-->
<script src="MyJsSourceCode.js"></script>
<script src="MyJsUnitTests.js"></script>
</head>
<body>
<div id="qunit"></div>
<div id="qunit-fixture"></div>
</body>
</html>
