I'm trying to load an html page inside a div. It works well, except that the "loaded" page only fills a small portion of the parent.
This is the function that loads the HTML:
function load_inner() {
Content.innerHTML='<object type="text/html" data="page_test.html"></object>';
}
The div that is to be filled is 500*200px.
The page that is loaded is supposed to fill the parent, but in this case the inner div is set to 1000*500px for testing purposes (the parent has the overflow property set to hidden).
This is the page that loads the content (everything is surrounded by the html tag):
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<meta name="generator" content="Geany 1.23.1" />
<style type="text/css">
#Content { width:500px; height:200px; background:orange; overflow:hidden;}
</style>
<script type="text/javascript">
function load_inner() {
Content.innerHTML='<object type="text/html" data="page_test.html"></object>';
}
</script>
</head>
<body onload="load_inner()">
<div id="Content"></div>
</body>
This is the page that is loaded (everything is surrounded by the html tag):
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<meta name="generator" content="Geany 1.23.1" />
<style type="text/css">
#Cont { background:yellow; }
body { margin:0px; padding:0px; }
</style>
</head>
<body>
<div id="Cont">
<span>IM A TEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEST</span>
</div>
</body>
And this is the result:
I've made some tests and it seems that this only happens with the object tag.
This works ok (the content is not "limited"):
Content.innerHTML='g...g';
If I send a GET request to the target page and set the innerHTML to the "responseText" it displays correctly:
function load_home() {
var url = "http://localhost/inner_load/page_test.html";
var method = "GET";
var async = true;
var request = new XMLHttpRequest();
request.onload = function () {
var data = request.responseText;
Content.innerHTML=request.responseText;
}
request.open(method, url, async);
request.send();
}
What is the problem with the object tag and how can this be solved? Thanks in advance!
If you set the width of the object to 100% that 100% reflects the width of the parent div (orange) not the content that is loaded - so you are loading a 1000px div into a 500px (100% of its parent) object tag. If you do not want scroll bars you need to size the object to be the same size as the content you are loading into it ie 1000px. So the answer is that there is nothing wrong with the object tag.
example:
<div id="content"> //500px
<object> //at 100% it is also 500px
<div>Loaded content</div> //this is 1000px and hence the scrollbar on a parent object
</object>
</div>

Scroll to the top of the page using JavaScript?

I want to have a button, and when you click on it, it will get you (the visitor) to the top of the page.
How can this be done?
Thanks
If you have a keyboard attached:
Press the 'Home' button.
The classic operation of hyperlinks is to point to a page different from the one being viewed, to navigate the site. It is also possible to create a link to a specific location on the current page, or to another page in order to position the browser correctly.
Creating an anchor is easy: you just have to assign the element to which you want to be able to point an identifier (with the attribute HTML id) and to associate a link starting with the character #, followed by the name of this Identifier.
Ex:
<div id="top">...</div>
It is then enough to make a link to this anchor:
top of page
Demo:
<!DOCTYPE html>
<html>
<head>
<title>top link</title>
<meta charset="UTF-8">
</head>
<body>
<div id="top">...</div>
<!-- Content -->
<!-- Content -->
<!-- Content -->
top of page
</body>
</html>
On button click, run the Javascript:
window.scrollTo(0, 0);
You can do it like this :
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

I am trying to duplicate Expanding Text Areas Made Elegant
Basically it explains how we can achieve something like fb comment box, where its size increases as text files the textarea.
I have this in my index.html:
<html>
<head>
<link rel="stylesheet" type="text/css" href="test.css">
<script src="test.js"></script>
</head>
<body>
<figure>
<div class="expandingArea">
<pre><span></span><br></pre>
<textarea></textarea>
</div>
</figure>
</body>
</html>
And my test.js looks like:
This doesn't really works.
However if I move everything inside the js file to a script tag inside body then it works fine. So my index file would look like:
<html>
<head>
<link rel="stylesheet" type="text/css" href="test.css">
</head>
<body>
<figure>
<div class="expandingArea">
<pre><span></span><br></pre>
<textarea></textarea>
</div>
</figure>
<script>
function makeExpandingArea(container) {
var area = container.querySelector('textarea');
var span = container.querySelector('span');
if (area.addEventListener) {
area.addEventListener('input', function() {
span.textContent = area.value;
}, false);
span.textContent = area.value;
} else if (area.attachEvent) {
// IE8 compatibility
area.attachEvent('onpropertychange', function() {
span.innerText = area.value;
});
span.innerText = area.value;
}
// Enable extra CSS
container.className += ' active';
}var areas = document.querySelectorAll('.expandingArea');
var l = areas.length;while (l--) {
makeExpandingArea(areas[l]);
}
</script>
</body>
</html>
You're not actually using onload
Your formatting is so messed up it's hard to tell, but your init code is in a while loop at the bottom after your onload function.
When you include it in the <head> it runs before any elements exist. That's why the position of it matters.
In your browser(I recommend Chrome for testing) open up the developer tools(via right click and selecting inspect element) and make sure your test.js file's path is correct. Do this by selecting the 'Sources' tab on the top of the developer tools window and then selecting the test.js file on the list of sources.
I also consider it best practice to load your js files at the bottom of your web documents(before the last body tag) to guarantee they load AFTER your dom elements load.
try this in your code:
I have used inside a table andapply a css class "form-control". The properties of this text areas are in side tag in side
html code:
<html>
<body>
<table>
<tr>
<td>Description:</td>

<td></td>
</tr>
</table>
//css-code required inside html:
<style>
textarea.form-control {
height: auto;
resize: none;
width: 300px;
}
</style>
</body>

I'm trying to do screen shot paste in my website using firefox. It can be done easily by giving the div as contenteditable='true'.

I can paste images from clipboard to particular div. Now the issue starts, how do I get the value from the div. For an example my user paste screenshot in the div and i want it to be save in db. If it normal textbox I can get the textbox value. Is there any way I can convert the DIV to image. Any advice and any referral links is highly appreciated.
document.addEventListener('DOMContentLoaded', function(){
var text = document.getElementById('apDiv1').innerText;
}, false);
To replace the div:
document.addEventListener('DOMContentLoaded', function(){
var el = document.getElementById("apDiv1");
var img = document.createElement("img");
img.setAttribute('src', '...');
el.parentNode.replaceChild(el, img);
}, false);
If I have some hidden element on a page, that contains some content, how can I create a link and when user clicks it, browser would open a new window and show the content (only the content, for example some json data)?
ps. I know that's probably bad idea to have some hidden content on the page. It's better to put an action link that will get the content from the server.. But it involves many other headaches and it wasn't me who created the page, so please just let me know if there's a comparatively easy solution...
Please use http://okonet.ru/projects/modalbox/index.html with inline content setting
You could pass the (URL encoded) contents of the hidden element as an argument in the URL when opening the second page. That argument could then be (unencoded and) inserted into the body of the second page when it loads.
The following example works locally on OS X. On other operating systems, the example may need to be placed on an actual web server before it will work:
page1.html:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

I'd like to display a div on a webpage when a user clicks on a button.
Does someone know how to do this ?
My code, so far, is :
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso 8859-1" />
</head>
<body>
<input id="text" type="text" size="60" value="Type your text here" />
<input type="button" value="When typing whatever text display the div balise on the page" onclick="check();" />
<script type="text/javascript">
function check() {
//Display my div balise named level0;
}
</script>
</body>
</html>
Thanks,
Bruno
EDIT: All my code (I've erased it because it was too long and not very clear)
You can use document.createElement("div") to actually make the div. Then you can populate the div using innerHTML for the text. After that, add it to the body using appendChild. All told, it can look like this:
function check() {
var div = document.createElement("div");
div.innerHTML = document.getElementById("text").value;
document.body.appendChild(div);
}
This will add a div every time the button is pressed. If you want to update the div each time instead, you can declare the div variable outside the function:
var div;
function check() {
if (!div) {
div = document.createElement("div");
document.body.appendChild(div);
}
div.innerHTML = document.getElementById("text").value;
}
If you have the div already in the page with an id of "level0", try:
function check() {
var div = document.getElementById("level0");
div.innerHTML = document.getElementById("text").value;
}
A quick search on google gave me this example:

The source-code for that example is:

top: 200px;
background-color: #f1f1f1;

display: none;
}
</style>
<script language="JavaScript">
function setVisibility(id, visibility) {
document.getElementById(id).style.display = visibility;
}
</script>
</head>
<body>
<input type=button name=type value='Show Layer' onclick="setVisibility('sub3', 'inline');";><input type=button name=type value='Hide Layer' onclick="setVisibility('sub3', 'none');";>
<div id="sub3">Message Box</div>
<br><br>
</body>
</html>
Paste this code somewhere in your body
<div id="myDiv" style="display:none">
Hello, I am a div
</div>
Add this snippet into your check() function to display the otherwise-hidden content.
document.getElementById("myDiv").style.display = "block";
You could also change the div content programmatically thus:
document.getElementById("myDiv").innerHTML = "Breakfast time";
... would change the text to 'Breakfast time'.
You might want to look into jquery, it'll make your life 100 times easier.
Jquery is a javascript library (script) that you include and it allows you to manipulate the DOM very easily.
Start by adding the latest Jquery to your head which will allow you to use something like $(document).ready( )
The function inside .ready( fn ) is a callback function; it get called when the document is ready.
$("#lnkClick") is a selector (http://api.jquery.com/category/selectors/)
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready( function() {
$("#lnkClick").click( function() {
$("#level0").attr("style", "display: block;width: 100px; height: 100px; border: solid 1px blue;");
});
});
</script>
</head>
<body>
<div id="level0" style="display:none;">
</div>
Click me
</body>
</html>
Of course this code can be made cleaner. You want to check: http://api.jquery.com/click/
There are plenty of examples.
Best of luck with Jquery!
you really should be using jquery , there's a little bit of a learning curve but once you get it, developing web apps is much easier.
<html>
<head>
<script src="http://code.jquery.com/jquery-1.5.2.min.js"></script>
<script>
$(document).ready(function() {
$("#show_div_button").click(function() {
$("#div_to_show").show();
return false;
});
});
</script>
</head>
<body>
Click Me to Show the Div
<div style="display:none" id="div_to_show">I will be shown when the link is clicked</div>
</body>
</html>
