I am using HTML object in below manner
<object id="foo" name="foo" type="text/html" data="mypage.aspx">
</object>
Now, I don't want to display complete data in mypage.aspx in HTML object/iframe. I just want to display a DIV layer from mypage.aspx in current page (default.aspx). I tried using data="mypage.aspx#div1" but didn't work.
For testing purpose mypage.aspx consists of
<body>
<div id="div1">This has to be displayed</div>
<div id="div2">This should not be displayed</div>
This portion also should not be displayed
</body>
How can I display only DIV1 part of mypage.aspx in HTML object?
If you can get rid of using object or iframe you can use jQuery load method to just get the required mark up from mypage.aspx. Keep a container in your parent page which will hold the required content from mypage.aspx and try this.
$(function(){
//Here container is a div in which #div1 from mypage.aspx will be loaded.
$('#container').load('mypage.aspx #div1');
});

I don't have an aspx capable server. So I tested using plain html, but the principle is the same really.
I recreated test.html:
<body>
<div id="div1">This has to be displayed</div>
<div id="div2">This should not be displayed</div>
This portion also should not be displayed
</body>
Then I made test2.html and for simplicity I embedded the JavaScript in test2.html:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>Test</title>
<script language="javascript"type="text/javascript">
function init() {
var obj = document.getElementById("foo"); // Grab the frame element
var kids = obj.contentDocument.body.childNodes; // Grab all child nodes of the body node of fram element
for( var i = 0; i < kids.length; i++ ) { // iterate through all child nodes
if( kids[i].id == "div1" ) { // if child node's id is "div1"
alert(kids[i].firstChild.nodeValue); // alert the first child of the div, e.g. text node, value
}
}
}
window.onload = init;
</script>
</head>
<body>
<object id="foo" name="foo" type="text/html" data="test.html"> </object>
</body>
</html>
This approach seemed the most cross-browser compatible naked javascript I could create. I'm not claiming that it's the best possible solution, though.
Here's some additional things you can do, I wrote comments for each. I commented one of the lines out because it makes a dramatic change I'm not sure you'd like. You can try it, though.

var myDiv = document.createElement("div"); //create a new div
myDiv.innerHTML = "<strong>Testing!</strong>"; // add some HTML to myDiv
var obj = document.getElementById("foo"); // Grab the frame element
var kids = obj.contentDocument.body.childNodes; // Grab all child nodes of the body node of fram element
for( var i = 0; i < kids.length; i++ ) { // iterate through all child nodes
if( kids[i].id == "div1" ) { // if child node's id is "div1"
kids[i].firstChild.nodeValue = "sts"; // change first text node to sts
kids[i].appendChild( myDiv ); //append myDiv to Div1
document.getElementById("container").innerHTML = kids[i].firstChild.nodeValue; // add text to container
//document.getElementById("container").appendChild(kids[i]); // actually append, or insert div1 into container2, this should move the div1 out of the frame and into the document
}
}
}
window.onload = init;

Through the following html and js code
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
var get = $(".parent").html();
// Now I want to add some properties to div with "hello-world-2" class in html code of get variable
</script>
</head>
<body>
<div class="parent">
<div class="hello-world">
<div class="hello-world-2">
<h1 class="hello-world-3" style="padding-top:10px;">simple</h1>
</div>
<div class="hello-world-4">
</div>
</div>
</div>
</body>
</html>
Here I want to add some properties such as id to the div or adding another div inside the div with class "hello-world-2" or add some cutom tags such as
h1 tag, img tag etc
Now I have the code of div inside html in "get" variable I want to add an id to div with "hello-world-2" class not to original code but to the hmtl code in get variable is it possible ? thanks
This should work:
var e1 = document.getElementById('someId').id = 'otherId';
var e2document.getElementsByClassName('hello-world-2')[0].id = 'someId';
var newElement = document.createElement('div');
newElement.id = 'someId';
newElement.classList.add('someClass');
newElement.setAttribute('custom-attr', 'ca');
var newElement2 = document.createElement('h1');
newElement2.innerHTML = 'HEADER';
e1.appendChild(newElement);
e2.appendChild(newElement2);

I've searched for html coding to print webpage image only when image (w585 w250), actual size of image, or a related button is clicked. I found coding that works perfectly yet prints my image really out of focus. The coding you show addresses this by stating focus and such, I've worked on this for near a month without success, Please help
You can try media queries in css to print the image.
Check naturalWidth and naturalHeight and compare with image width and height so if they match then print page.
function printCoupon() {
var timeout = 1000;
var naturalWidth = $('#img')[0].naturalWidth;
var naturalHeight = $('#img')[0].naturalHeight;
var width = $('#img').width()
var height = $('#img').height();
if (naturalWidth == width && naturalHeight == height) {
self.focus();
window.print();
setTimeout("self.close()", timeout);;
self.focus();
}
}

I'm new for web developing. I want to display images in grid layout. my images have same width but different height.
To display images without gap between them i used masonry plugin. But it doesn't work for me. Can anyone help me find out the error please..
This is my code
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>FlashTemplatesDesign </title>
<script type="text/javascript" src="lib/jquery.tools.js"></script>
<script type="text/javascript" src="lib/masonry.pkgd.min.js"></script>
<script>
var container = document.querySelector('#test');
var msnry = new Masonry( container, {
// options
columnWidth: 200,
itemSelector: '.imagedisplay'
});
</script>
</head>
<body>
<div id="test">
<?php
// Connects to your Database
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("selfie") or die(mysql_error()) ;
//Retrieves data from MySQL
$data = mysql_query("SELECT * FROM image_upload INNER JOIN user_table
ON image_upload.user_id=user_table.user_id ORDER BY timestamp DESC; ") or die(mysql_error());
//Puts it into an array
while($info = mysql_fetch_array($data)){
//Outputs the image and other data
Echo
'<div class="imagedisplay">' .'<img src="uploads/'.$info['image'].'" width="230px" height=auto border="1px solid #"
-webkit-border-radius=" 20px"
-moz-border-radius= "20px"
border-radius="20px"
>'. '</div>';
}
?>
</div>
</body>
</html>
Right off hand it looks like you're trying to reference the images and container in your JavaScript before the document is loaded. Try moving your script tag with code after (or right before) the closing </body> tag.
Because the document hasn't fully loaded, the DOM API in JavaScript can't yet access those elements if your JavaScript is in the head.
You'll need to wait for the images to load before you organize the elements with masonry.
From masonry appendix:
// initialize Masonry after all images have loaded
imagesLoaded( container, function() {
msnry = new Masonry( container );
});
Is it possible to convert a link to an external SVG such as http://upload.wikimedia.org/wikipedia/en/4/4a/Commons-logo.svg to an element?
My first approach was to grab the source code of the svg page, but this is not possible for external sources in Javascript.
This cleanest way to load an svg file inline, is to create a DIV on your web page and load the svg file via XMLHttpRequest and place the response text into the DIV using innerHTML
You can then inspect/change the file as needed.
Below is an example the calls your file into the web page:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Load SVG file file Inline</title>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
</head>
<body style='padding:0px;font-family:arial'>
<center><h4>Load SVG file Inline</h4>
<div style='width:90%;background-color:gainsboro;text-align:justify;padding:10px;border-radius:6px;'>
Load an svg file as inline SVG. This provides dynamic svg applications seamless DOM access to its elements. Uses <b>XMLHttpRequest</b>. It can be loaded as a DIV's <b>innerHTML</b> via a string dump (<b>responseText</b>).
</div>
<div id="svgDiv"></div>
<p><button onClick=changeSomeValues()>change</button></p>
SVG DOM:<br />
<textarea id=mySvgValue style='width:90%;height:200px;font-size:120%;font-family:lucida console;'></textarea>
<br />Javascript:<br />
<textarea id=jsValue style='border-radius:26px;font-size:110%;font-weight:bold;color:midnightblue;padding:16px;background-color:beige;border-width:0px;font-size:100%;font-family:lucida console;width:90%;height:400px'></textarea>
</center>
<div id='browserDiv' style='padding:3px;position:absolute;top:5px;left:5px;background-color:gainsboro;'></div>
<script id=myScript>
function loadSVGasXML()
{
var SVGFile="http://upload.wikimedia.org/wikipedia/en/4/4a/Commons-logo.svg"
var loadXML = new XMLHttpRequest;
function handler(){
if(loadXML.readyState == 4 &&loadXML.status == 200){
svgDiv.innerHTML=loadXML.responseText
mySvgValue.value= svgDiv.innerHTML
}
}
if (loadXML != null){
loadXML.open("GET", SVGFile, true);
loadXML.onreadystatechange = handler;
loadXML.send();
}
}
//--button---
function changeSomeValues()
{
path4653.style.fill="green"
mySvgValue.value=svgDiv.innerHTML
}
</script>
<script>
document.addEventListener("onload",init(),false)
function init()
{
loadSVGasXML()
jsValue.value=myScript.text
mySvgValue.value=svgDiv.innerHTML
}
</script>

I'm following a tutorial to create a slideshow with JavaScript and HTML.
The first image and the "Next" and "Previous" buttons are on the page however when I click on next or previous it says this webpage can not be found. Can someone help me please?
The tutorial can be found here and I have also included the HTML and JavaScript code below.
The html code is:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/
xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Image Slideshow</title>
<script type="text/javascript"
src="script09.js"></script>
</head>
<body bgcolor="#FFFFFF">
<div align="center">
<h1>Welcome, Robot Overlords!</h1>
<img src="images/robot1.jpg"
id="myPicture" width="200"
height="400" alt="Slideshow" />
<h2><a href="previous.html"
id="prevLink"><<
Previous</a> <a
href="next.html" id="nextLink">Next
>></a></h2>
</div>
</body>
</html>
and The JavaScript code is
window.onload = initLinks;
var myPix = new Array("images/robot1.jpg",
"images/robot2.jpg","images/robot3.jpg");
var thisPic = 0;
function initLinks() {
document.getElementById("prevLink").
onclick = processPrevious;
document.getElementById("nextLink").
onclick = processNext;
}
function processPrevious() {
if (thisPic == 0) {
thisPic = myPix.length;
}
thisPic--;
document.getElementById("myPicture").src =
myPix[thisPic];
return false;
}
function processNext() {
thisPic++;
if (thisPic == myPix.length) {
thisPic = 0;
}
document.getElementById("myPicture").src =
myPix[thisPic];
return false;
}
Rather than bind your function in a onload init function, try:
<a href="previous.html" id="prevLink" onclick="processPrevious();return false;">
Chances are your have a js error on the page so the functions are ignored and the a tags just follow the link you have used. Open up the console of your browser and check for syntax errors.
You have given HTML page url in href of both the links.
But I think you just need to change the image src attribute...
Use href="javascript:" in both the links. So there is no need of event.preventDefault() in this case...
(href="#" scrolls the page to the top).... :)
