I tried to show the div tag to another frame set while checkbox click.
My index.html file is
<html>
<head>
<title></title>
</head>
<frameset cols="25%,75%">
<frame src="left-panel.html"></frame>
<frame src="right-panel.html"></frame>
</framset>
</html>
left-panel.html
<html>
<body>
<script src="min.js"></script>
<script src="file.js"></script>
<input type="checkbox" value = "1" class="theClass">Click<h1>
<input type="checkbox" value = "2" class="theClass">Click<h1>
<input type="checkbox" value = "3" class="theClass">Click<h1>
</body>
</html>
right-panel.html
<html>
<body>
<script src="min.js"></script>
<script src="file.js"></script>
<div id="footer" style="width:98%; background:blue; height:10%; position:absolute; bottom:0; visibility:hidden;"></div>
</body>
</html>
Then my js file is
$('.theClass').change(function(){
($('.theClass:checked').map(function(){ myfunction(this.value); }).get())
});
function myfunction(ad)
{
document.getElementById("footer").innerHTML = ad;
}
When click the checkbox I want to display these checkbox value into the footer div in another html
First define the names of the frames:
<frameset cols="25%,75%">
<frame name="left" src="left-panel.html"></frame>
<frame name="right" src="right-panel.html"></frame>
</framset>
And then in the javascript:
function myfunction(ad) {
top.left.document.getElementById("footer").innerHTML = ad;
}
You can access only to parent:
function myfunction(ad) {
parent.left.document.getElementById("footer").innerHTML = ad;
}
First, the sub-frames should have the same origin(same domain) in order to manipulate them.
Then, get the parent frame by parent.
Get the sub-frame by (according to http://javascript.info/tutorial/frames-and-iframes):
window.frames[0] - access by number
window.frames['iframeName'] - access by iframe name
So the answer is
$().ready(function(){
$("#cli").hover(function () {
parent.frames[1].$("#footer").css("visibility","visible");
},
function () {
parent.frames[1].$("#footer").css("visibility","hidden");
});
});
edit: sorry to find that the question is modified.
Each frame is a diferent web, with his own copys of the JS variables, for security reasons one page cant modify other page using JS. For example, when you call document variable from leftpanel, is diferent than the document variable called from rightpanel, and diferent tha the document variable called from index.html
Remember JS is executed in client side.
Maybe you must to use two divs:
your.css
#wrapper {
}
#left {
float: left;
width: 75%;
background-color: #CCF;
}
#right {
float: right;
width: 25%;
background-color: #FFA;
}
#cleared {
clear: both;
}
index.html
<html>
<head>
<title></title>
<link rel="stylesheet" href="your.css">
<script src="min.js"></script>
<script src="file.js"></script>
</head>
<body>
<div id="wrapper">
<div id="left">
<input type="checkbox" value = "1" class="theClass">Click<h1>
<input type="checkbox" value = "2" class="theClass">Click<h1>
<input type="checkbox" value = "3" class="theClass">Click<h1>
</div>
<div id="right">
<div id="footer" style="width:98%; background:blue; height:10%; position:absolute; bottom:0; visibility:hidden;"></div>
</div>
<div id="cleared"></div>
</div>
</body>
</html>
If you wants to use frames, maybe you must use PHP with ajax to make the changes in the server side

i started to use math.js just for convenience and i was wondering if i could use math.sum method and pass
a collection of input values as argument and return the sum of all input values,for example,something like this :
code to visualize my concept :
$(document).ready ( function(){
$("#sum").val(math.sum($("#container input")))
});
input{
position:relative;
float:left;
clear:both;
text-align:center;
}
#sum{
margin-top:5px;
}
<!DOCTYPE html>
<html>
<head>
<script src=https://cdnjs.cloudflare.com/ajax/libs/mathjs/3.3.0/math.min.js></script>
<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
</head>
<body>
<div id="container"><input value="15"><input value="5"><input value="10"><input value="20"></div>
<input id="sum" placeholder="SUM OF ABOVE INPUTS">
</body>
</html>
Your math.sum method expects a JS Array so you need to build it from what you have to comply with the requirement.
In just one line you can go from Jquery Objects to your expected Array.
[Jquery DOM Elements].get() => [ES6 DOM Elements].map() => JS Arrays
$("#sum").val(math.sum($("#container input").get().map(v=>v.value)))
input {
position: relative;
float: left;
clear: both;
text-align: center;
}
#sum {
margin-top: 5px;
}

<div id="container"><input value="15"><input value="5"><input value="10"><input value="20"></div>
<input id="sum" placeholder="SUM OF ABOVE INPUTS">

You need to map the element values to an array first.
The math library doesn't know anything about getting values from a jQuery collection of elements
Simple case with no validation:
const values = $("#container input").toArray().map(el => el.value)
$("#sum").val(math.sum(values))
input {
position: relative;
float: left;
clear: both;
text-align: center;
}
#sum {
margin-top: 5px;
}

I'm trying to make a simple HTML file with a checkbox and a javascript that change the color of the checkbox when clicked. The problem is that the javascript file is not called, so clicking the button is useless as the javascript code is not being read. It seens very simple but I can't see what am I doing wrong:
HTML code:
<!DOCTYPE html>
<html>
<head>
<script src="and_gate.js" defer></script>
</head>
<body style= "background-color: white;">
<label id=in1 class="container1" onclick="in1(element1)">0
<input type="checkbox">
</label>
<style>
.container1 {
background-color:green;
font-size: 2vw;
}
</style>
</body>
</html>
Javascript code:
alert('clicked')
funtion in1(element1){
element1.style="background-color:red;"
}
In an inline event handler, you can use this to refer to the target of the event.
You also misspelled function. And the alert needs to be inside the function.
function in1_fun(element1) {
alert('clicked')
element1.style = "background-color:red;"
}
.container1 {
background-color: green;
font-size: 2vw;
}
<label id=in1 class="container1" onclick="in1_fun(this)">0
<input type="checkbox">
</label>
It's also not a good idea to use the same name for your function as the ID of the element. Both of these become global variables, and it's possible for the ID variable to replace the function variable.
In JavaScript and HTML, when you pass a JS function to the onclick property of an element, the function doesn't know about the element that's calling it. You need to pass it some way to find that element, like an id (or the outer context through this, which I missed, and as Barmar points out in his excellent answer).
You can then use this ID with a function like document.getElementById() to find the desired element in the DOM, and do something with it, in this case change it's style property.
You also misspelled function as "funtion", which will cause it not to be processed as a function.
function in1(id) {
document.getElementById(id).style = "background-color:red;"
}
<!DOCTYPE html>
<html>
<head>
<script src="and_gate.js" defer></script>
</head>
<body style="background-color: white;">
<label id=in1 class="container1" onclick="in1('in1')">0
<input type="checkbox">
</label>
<style>
.container1 {
background-color: green;
font-size: 2vw;
}
</style>
</body>
</html>
I'm working on an application with modal overlays that appear within iFrames when the corresponding buttons are pressed. To close one of these modal overlays, the Cancel button is defined in the parent window this way:
Cancel
I'd like to replace this with a JavaScript function (let's call it onCancel() ) so I can reset some values if needed in addition to closing the overlay. What is the JavaScript equivalent to "#close"?
You can't close an iFrame, you either have to remove or hide it. The example below removes the iframe. If you just want to hide you can replace the last line (containing removeChild with this one frame.style.display="none"; You can then get it back by using this line frame.style.display="block";
<!DOCTYPE html>
<head>
<title>test</title>
<style type="text/css">
.top {
height: 100px;
width: 200px;
background-color: blue;
}
</style>
<script type="text/javascript">
function removeIFrame() {
var frame = document.getElementById("iframe");
frame.parentNode.removeChild(frame);
}
</script>
</head>
<body>
<div class="top" onclick="removeIFrame();"></div>
<iframe id="iframe" src="/" width="200" height="100"></iframe>
<div class="top"></div>
</body>
<!DOCTYPE html>
<head>
<title>test</title>
<style type="text/css">
.top {
height:100px;
width:200px;
background-color:green;
}
</style>
<script type="text/javascript">
function removeIFrame() {
var frame = document.getElementById("target");
frame.parentNode.removeChild(frame);
}
</script>
</head>
<body>
<div class="top" onclick="removeIFrame();"></div>
<iframe id="target" src="http://www.disney.com" width="100" height="100"></iframe>
<div class="top"></div>
</body>
The approach that works for me is to define the following JavaScript function in the parent page:
function onCancel()
{
var myIFrame = document.getElementById("myIFrame");
var myForm = myIFrame.contentDocument.myForm;
var stuffWasChanged = myIFrame.contentDocument.stuffWasChanged;
if (stuffWasChanged == "true")
myForm.action = "reset.do";
myForm.submit();
location.href = '#';
}
Note that if the stuffWasChanged flag was not set to true, then no action is defined for the form in question, so the modal overlay simply goes away without any servlet method being called.
I want to create a website where I can write and preview a website. The problem is that I want to preview it in an iframe, because then the website isn't influenced by the HTML code around the iframe.
Is there a way to show a webpage in an iframe tag with a string as source instead of an URL?
This is how it should look (just an iframe).
<textarea onkeyup="document.getElementById("body").innerHTML=this.value;"></textarea>
<div id="body"></div>
In fact, JSFiddle does the same, so there must be a way. Ideas?
You can modify the content of the document specified by the src attribute, using contentWindow.document. So, assuming you had a <textarea> with the markup you want to preview, you could do something like this:
Editor document:
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<title>Edit iframe example</title>
<style>
.editors, .preview { float: left; display: block; }
.editors { width: 500px; margin-right: 25px; }
.editors textarea { width: 100%; height: 300px; }
.preview { width: 800px; }
.preview iframe { width: 100%; height: 800px; }
</style>
</head>
<body>
<div class="editors">
<p>
<label>CSS</label>
</p>
<p>
<textarea id="preview-editor-CSS" onkeyup="updatePreviewCSS(this)"></textarea>
</p>
<p>
<label>HTML</label>
</p>
<p>
<textarea id="preview-editor-HTML" onkeyup="updatePreviewHTML(this)"></textarea>
</p>
</div>
<div class="preview">
<iframe id="preview" src="preview.html"></iframe>
</div>
<script>
function updatePreviewHTML(elem) {
var frame = document.getElementById('preview');
var content = elem.value;
frame.contentWindow.document.body.innerHTML = content;
}
function updatePreviewCSS(elem) {
var frame = document.getElementById('preview');
var content = elem.value;
frame.contentWindow.document.getElementsByTagName('style')[0].innerHTML = content;
}
</script>
</body>
</html>
The "preview" document:
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<title>Preview iframe example</title>
<style></style>
</head>
<body>
</body>
</html>
I've only tried this locally, on Firefox 31, so caveat emptor.
I'm trying to set the default focus on an input box when the page loads (example: google).
My page is very simple, yet I can't figure out how to do this.
This is what I've got so far:
<html>
<head>
<title>Password Protected Page</title>
<script type="text/javascript">
function FocusOnInput()
{
document.getElementById("PasswordInput").focus();
}
</script>
<style type="text/css" media="screen">
body, html {height: 100%; padding: 0px; margin: 0px;}
#outer {width: 100%; height: 100%; overflow: visible; padding: 0px; margin: 0px;}
#middle {vertical-align: middle}
#centered {width: 280px; margin-left: auto; margin-right: auto; text-align:center;}
</style>
</head>
<body onload="FocusOnInput()">
<table id="outer" cellpadding="0" cellspacing="0">
<tr><td id="middle">
<div id="centered">
<form action="verify.php" method="post">
<input type="password" name="PasswordInput"/>
</form>
</div>
</td></tr>
</table>
</body>
</html>
How come that doesn't work while this works fine?
<html>
<head>
<script type="text/javascript">
function FocusOnInput()
{
document.getElementById("InputID").focus();
}
</script>
</head>
<body onload="FocusOnInput()">
<form>
<input type="text" id="InputID">
</form>
</body>
</html>
Help is much appreciated :-)
And you can use HTML5's autofocus attribute (works in all current browsers except IE9 and below). Only call your script if it's IE9 or earlier, or an older version of other browsers.
<input type="text" name="fname" autofocus>
This line:
<input type="password" name="PasswordInput"/>
should have an id attribute, like so:
<input type="password" name="PasswordInput" id="PasswordInput"/>
This is one of the common issues with IE and fix for this is simple.
Add .focus() twice to the input.
Fix :-
function FocusOnInput() {
var element = document.getElementById('txtContactMobileNo');
element.focus();
setTimeout(function () { element.focus(); }, 1);
}
And call FocusOnInput() on $(document).ready(function () {.....};
You could also use:
<body onload="focusOnInput()">
<form name="passwordForm" action="verify.php" method="post">
<input name="passwordInput" type="password" />
</form>
</body>
And then in your JavaScript:
function focusOnInput() {
document.forms["passwordForm"]["passwordInput"].focus();
}
