have a very basic page that I am working on that contains thumbnail images and a main image. When the thumbnail images are clicked I am using document.getElementById to change the main image. Easy to do but I now want to change my main image from landscape to portrait. This will mean that now when clicking the thumbnail I will not only need to change the main image but also the div tag dimensions. I am new to Javascript and was wondering if someone could give me a quick point in the right direction of how to go about this.
Thank you in advance for any help,

I would suggest adding/changing a CSS style class on the element and then configuring that class with all the necessary modifications. There's a lot you can do with just CSS.
You can either use a semi colon in your onclick event and add more javascript calls, or create a JavaScript function that will do all of your neccesary changes and call that method from your onclick event.
function changeStuff(){
document.getElementById("myThing").DoStuff()
document.getElementById("myOtherThing").DoOtherStuff()
}
<div id="myThing">
<img id="myOtherThing" onclick="cangeStuff();"></img>
</div>

Goal: I need to set anchor tags for the wordpress-site: http://joy-academy.eu/programs/
I am using Visual Composer and there is some animation.
Problem: If I try to set an anchor tag, it scrolls to the right place but does not show the previous parts that are animated like here:http://joy-academy.eu/programs/#example or if I use a Plugin "scroll to Id", it just scrolls to a random place, like for example here: http://joy-academy.eu/programs/#cc
Details: The Wordpress Theme is "Zyen". Ref: https://themeforest.net/item/zeyn-multipurpose-wordpress-theme/8848292
Thanks for your help!
I see that your site is using the Zeyn theme.
That's the first place to look for coding style changes. Here's a demo example doing what I think you are hoping to achieve. http://djavaweb.com/selector.php?theme=zeyn-classic
This means don't use the button for an anchor. So, use the Extra id in the rows to correspond with the anchor link (#example).
Here's the directions to do this; just start after the steps about the menu items.

In my gwt-application i got a tree with a few images. These images can be copied by drag and drop to a panel. Now i want to make them resizable in this panel. when i test my css-code with a concrete image-path for "background-image", resize:both and background-size:cover works! My problem is, that i cannot set a concrete url to the css, becacuse the imagepath is dynamic.
when i delete background-image from css and set backgroundimage in my code, the surrounding container resizes, but the image not. Is it possible to set 'background-image' to the image that I choose during runtime? how can i solve that with css?
Thank you!!
You can set background image at any time in your code. For example:
myPanel.getElement().getStyle().setBackgroundImage("url(/myImage.jpg)");
To make it resizable, you need to apply the correct CSS to this panel. There are several CSS options for you to consider.
I am using angular and I need to add an animation that will increase the size of the image.
<div class="card">
<div class="item images-parent">
<img src="img/carryout-icon.jpg" class="left-image"></img>
<img src="img/or.jpg" class="center-image"></img>
<img src="img/delivery-icon.jpg" class="right-image"></img>
</div>
</div>
demo:
http://play.ionic.io/app/933b5926b6da
I want to add same animation/transition to first and third image when the user clicks on it and should be removed when user clicks on the other one i.e if I click on first image, it increases in size, then if I click on the other one, first one goes back to normal and second one has that animation.
Also, I have tried doing it but I am just not able to get ngAnimate, I am not a CSS person either. Also, Any resources to help someone like me would be appreciated.
I see events such as ngView , ng if e.t.c But I do not really want these animations on such events. Only when user clicks on the image. Am I even supposed to use ngAnimate here?
I do not know which particular image you intend to increase it's size on click, but here's one way to go about it.
You can create a css class that increases the image, and you toggle on or off with NgClass, A tutorial Scotch.io
That is to make sure it changes class, but if you want to toggle on/off the class when you click CodePen snippet below
$scope.isActive = false;
$scope.activeButton = function() {
$scope.isActive = !$scope.isActive;
}
I am drawing an image inside panel and slider field using ExtJS 4. I want to change opacity of image whenever of value of slider field changes.
I am aware that opacity and filter:alpha(opacity=); rule of CSS can be applied to image which will change its opacity.
However I do not know how to apply this css rule to the image. Can anyone please guide me on this?
You can use Ext.dom.Element.setOpacity method:
Ext.fly('image-id').setOpacity(0.5); // this will make img with id 'image-id' become half-transparent
Here is live demo
Update
If you are using Ext.Img component you will have to do something like the following:
imgCmp.getEl().setOpacity(0.5);
I have been searching on the Google Map API V3 documentation but I could not find any way to use my own html content instead of an image to create a custom icon on the map.
I would like to display a dynamic marker that can display text or anything I want.
For exemple :
<div class="marker">Dynamic text</div>
I have seen this thread google map api v3: can I use a div instead of an image to create the custom icon? where someone advice to use "Custom Overlays" but in the documentation it only displays an image... I don't see the point of explaning how to display an image with "Custom Overlays" if it is done to display html content.
http://code.google.com/apis/maps/documentation/javascript/overlays.html#CustomOverlays
How should I proceed then ? Should I use Custom Overlays ? There is not anything that seem easier to do that ?
Mano's got the right answer if you're looking to position something on the map that isn't bounded geographically, like a menu or titlebar.
If you're looking to display something geographically-bound, like a city name (pretending for a second that the API doesn't already do this) than you'll be headed the CustomOverlay route. While all the examples use images, that's not a requirement by any means. If you look at the simple overlay example and view the source code around line 62 you'll see the exact lines adding the <img> object to the <div>. You could just as easily add text to the div instead of an image.
Actually you can use float the div over your map using CSS. You have to be careful about the positioning. Check out this post:
div on top of div with Google Maps API
Go to this demo purpose website: http://easysublease.org/mapcoverjs/
On the map, right Click on map, and you will see a context menu. Within this context menu, there is a input, you can just input some text on the input. Then next generated Marker will have the text you entered there.
To see how it works, you can go to its github: https://github.com/bovetliu/mapcover.
