I need to change the background image of a div using an onhover function.
I have tried several iterations of "document.getElementByID" without success
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Photo Gallery</title>
<link rel="stylesheet" href="css/gallery.css">
<script src = "js/gallery.js"></script>
</head>
<body>
<div id = "image">
Hover over an image below to display here.
</div>
<img class = "preview" alt = "Styling with a Bandana" src =
"https://s3-us-west-2.amazonaws.com/s.cdpn.io/389177/bacon.jpg"
onmouseover = "upDate(this)" onmouseout = "unDo()">
</body>
</html>
Following is the latest function I tried:
function upDate(previewPic){
document.getElementById("image").body.backgroundImage =
"url('img_bacon.jpg')";
I am expecting the div to include the background image but it does not.
Try using .innerhtml and pass in whatever you want the body to be.
document.getElementById("image").innerhtml = "<div>CONTENT HERE</div>"
This should work:
document.getElementById("image").style.backgroundImage = "url(someimage.jpg)";
You could consider using jquery.. then it would look something like this:
$('#image').css("background-image", "url(someimage.jpg)");

So I want to include my navbar to every page. I use #extends in laravel and When I define any html elements, It just goes above the navbar. It does not make sense at all. I write the html elements under the navbar but why does it go on top?????
here is my code:
<!DOCTYPE html>
<html lang="en">
#extends('layout.header')
<style>
</style>
</head>
<body>
#extends('layout.navbar')
asdasdsa
</body>
</html>
I seem to have a very specific problem where something is missing and I just can't see it.
From and index.html:
<!DOCTYPE HTML>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="javascript" type="text/javascript" src="./js/a1.js"></script>
<script language="javascript" type="text/javascript" src="./js/a2.js"></script>
<style>
</style>
</head>
<body onLoad="javascript:Scan()">
<div id = "TheDiv">?
</div>
</body>
</html>
From onLoad, I call Scan()
function Scan()
{
divResultado = document.getElementById('TheDiv');
//instanciamos el objetoAjax
ajaxScan=objetoAjax();
ajaxScan.open("GET", "myscan.php", true);
DBScan = setTimeout(Scan,15000 );
ajaxScan.onreadystatechange=function()
{
if (ajaxScan.readyState==4)
{
//mostrar resultados en esta capa
divResultado = ajaxScan.responseText;
}
};
ajaxScan.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
ajaxScan.send( );
}
myscan gets data from a database and in debug, I see that information is properly transfered to divResultado above.
But the data doesn't appear in the div with id = "TheDiv"
I've done this hundreds of times before, but something somwhere has made itself
invisible to me.
In the raw data HTML, I think it appears below and outside of the context.
What am I not seeing
Because you're not writing the data to the page, you're just assigning it to a variable:
divResultado = ajaxScan.responseText;
Which means divResultado no longer refers to the element on the page, it now refers to the text from the AJAX response.
To set the text to that element, try:
divResultado.innerText = ajaxScan.responseText;
Or, if the result is HTML:
divResultado.innerHTML = ajaxScan.responseText;
I have done literally everything to make it work but it is not working yet
I loaded from cdn just as it is in the preview documentation

To enhance into a filepond element I have
<script>
const inputElement = document.querySelector('input[type="file"]');
const pond = FilePond.create( inputElement );
</script>
and lastly
<input type="file">
It just shows up as a file and not with image preview. What am I missing?
The plugins have not been registered with FilePond.
This should work:

I'm looking at the docs and I see how this is confusing, will improve them as soon as I have some time.
I want to format numeric column value as 55,25,236.30 in grid. I created a JS function and called from column template in grid. My JS function:
function NumberFormater(Price) {
kendo.culture("en-US");
kendo.cultures.current.numberFormat.groupSize = [3,2];
return kendo.toString(Price, "##,#.00");
}
but the value is showing like 5,525,236.30. According to this link the default value for groupSize is [3]. Is it not possible to set multiple values like [3,2] like numberformat in C#?
Make sure that the NumberFormater function receives a numeric argument. Below is a test page that works.
On a side note, I am not sure there is a need to set the culture and groupSize every time you execute the function.

I have a simple page which uses the mediaelement.js audioplayer plugin. The player attaches and functions correctly when loaded normally. However, when the page is loaded via ajax, the mediaelementplayer does not attach to the audio tag.
I use this code to call the file via ajax and jquery:
<html>
<head>
<link href="/test-vocabulary.css" rel="stylesheet" type="text/css">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script>
$(document).ready(function(){
$(".ajax_vocab_link").click(function(evento){
evento.preventDefault();
var ajaxDivNum = $(this).attr('id').split('_')[1];
var searchTerm = $(this).attr('title');
$("#ajaxcontainer_"+ajaxDivNum).load("test-audioplayer-se.php", {chrisSearch: searchTerm}
);
});
})
</script>
</head>
<body>
<p><button class='ajax_vocab_link' id='ajaxlink_1' title='clothes'>Link to load ajax doc</button></p>
<div class='ajax_vocab_container' id='ajaxcontainer_1'>This is div id ajaxcontainer_1</div>
</body>
</html>
The audioplayer page is:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<script>
$(document).ready(function() {
$('#audio-player-vocab0').mediaelementplayer({

audioVolume: 'horizontal',
audioWidth: 400,
audioHeight: 120
});
});
</script>
</head>
<body>
<div class='display_vocab_container' >
<div class='display_vocab_text' >
<div class='audio-player-slim'>

</div>
</div>

</html>
I've tried many combinations including using on, live, success and moving the css/js links between the documents, but these have all made the situation worse.
What can i do get the file to attach medaielementplayer when loaded via ajax?
Try to put the mediaelementplayer() function call in the ajax success function, that worked for me. So unless you want to use .ajax instead of .load you'll need to pass it as the second argument to the load function. Or use http://api.jquery.com/ajaxSuccess/
$(".ajax_vocab_link").click(function(evento) {
evento.preventDefault();
var ajaxDivNum = $(this).attr('id').split('_')[1];
var searchTerm = $(this).attr('title');
$("#ajaxcontainer_"+ajaxDivNum).load("test-audioplayer-se.php", function() {
$('#audio-player-vocab0').mediaelementplayer({
alwaysShowControls: true,
features: ['playpause'],
audioVolume: 'horizontal',
audioWidth: 400,
audioHeight: 120
});
});
});
