I am using jQuery ImageAreaSelect for image area selection like this:
$('#image').imgAreaSelect({}); //#image is a img id
Below this image, I have a bunch of image thumbnails, clicking on which will populate that image as #image. This way user can load each image and then select its area.
My problem is that when a new image is loaded, the dotted line which indicates the area selected for previous image still remains and gets shown on the newly loaded image. I do not want this and want this to go away every time a new image is loaded.
I read and tried this answer and this answer but they are not working for me...
My current (non-working) code is:
$('#load').click(function() {
$('#image').imgAreaSelect({hide:true,remove:true}); //try to remove old instance
$('#image').imgAreaSelect({}); //create new instance...
});
Any help is appreciated.
I have never used such pluggin but the documentation explains how to disable/re-enable it.
Save the variable when you initialize the pluggin
var ias = $('#image').imgAreaSelect( // your original initalization
Then call disable on it as the documentation states:
ias.setOptions({hide:true,remove:true})
Try this way
$('#load').click(function() {
$('#image').cancelSelection();
});

I'm trying to get the style of the icon which I clicked on, in order to get its translate values.
I'm doing this because I want to create a div that will have the same location on the map as the icon who got clicked on.
this is my website so far:
http://www.david-halfon.com/radio/index.html
Basically, each time someone presses the yellow circle, a div should appear around it.
this is the code for events that happen when an icon is being clicked:
locale.on('click', function(e) {
$("#music").attr("src", prop.Url);
$(".player").show();
play();
sendWithAjax(prop.Country, prop.City);
$("h1").html(prop.Station);
$("h2").html(prop.Country);
$("h3").html(prop.City);
//console.log($(this).css("transform"));
//console.log($(this).attr("style"));
console.log($(this));
setTimeout(function(){ $("h4").html(globalVar);}, 500);
$(".plusB").show();
$(".shareB").show();
map1.setView(locale.getLatLng(), 4);
playNow = prop.Station;
playNowCountry = prop.Country
playNowCity = prop.City;
});
The comments are what I have tried to do so far but it does'nt seems to work.
When I'm trying to consloe.log(this) I get 'undefined'.
Thank you!!
The reason why you don't get the expected $(this).css(...) informations is that this is not a regular DOM object, as it clearly appears using Firebug:
The <img> you want to get style from is contained in the _icon member of this object, so you can use e.g.:
console.log($(this._icon).css('transform'));
console.log($(this._icon).attr('style'));
// and so on
This way (tested using Firebug on your website), it works fine.
BTW, I couldn't figure out why the click event targets this object rather than the <img>...
BTW again, this website is a great idea: cool!
I am trying to put a photo view/slideshow on my webpage and I am not getting the results I am looking for. I have created a Fiddle HERE to show you what I am trying to do. What I want it to do is when you click a thumbnail it switches the thumbnail into the main photo spot and the main photo into the thumbnail spot. It works at first but after you start clicking the other thumbnails it starts not switching the correct photo into the main slot. Also if you reclick the thumbnail you just clicked it does nothing. Here is my jquery code but take a look at my fiddle and you will be able to see what I am trying to do.
$('.thumb1').click(function() {
$('.thumb1, .main').fadeIn().toggleClass('thumb1 main');
});
$('.thumb2').click(function() {
$('.thumb2, .main').fadeIn().toggleClass('thumb2 main');
});
$('.thumb3').click(function() {
$('.thumb3, .main').fadeIn().toggleClass('thumb3 main');
});
$('.thumb4').click(function() {
$('.thumb4, .main').fadeIn().toggleClass('thumb4 main');
});
I changed your classes similarly to how Joao did, but my JavaScript is a little different
$('.thumb').click(function () {
var newHTML = this.innerHTML;
this.innerHTML = $('.main')[0].innerHTML
$('.main').html(newHTML);
});
Instead of just changing the src, you will also keep all other attributes of the images, such as the alt attribute, which you should add to your images for accessibility purposes.
I didn't implement the idea of not having clicking the same one do nothing, because then if they want to look at the image they just looked at they can't.
JSFiddle: http://jsfiddle.net/howderek/RfKh4/6/
I was looking at your code, and I wouldn't recommend switching around classes between elements like that since it might throw out a couple of bugs like yours. I played around with your code and simplified a little bit:
$('.thumb').click(function () {
var previousSrc = $('.main').children().attr('src');
$('.main').children().attr('src', $(this).children().attr('src'));
$(this).children().attr('src', previousSrc);
});
Here's the updated fiddle: http://jsfiddle.net/RfKh4/5/
Basically what I did was save the previous src attribute of the .main div image inside previousSrc and then I change the div's image to the one in the thumbnail. And finally change the thumbnail's image to the one that was on the .main div. Hope it helps you!
The application I'm working on allows users to add an unlimited number of images onto a viewport. With those images, a series of operations are allowed: resize, drag, rotate, and crop. For the cropping feature, I'm using the Jcrop plugin.
When clicking on the control icon for cropping, a lightbox appears, that shows the selected image (the <img> element is one and the same, only the src attribute value changes each time) and allows the user to crop it. The event handler associated triggered when the crop icon is clicked is:
$(document).on("click", "div.cropper", function(){
var ctrl = $(this),
ref = ctrl.attr("reference"),
obj = returnObj(objects,ref),
target = $("#crop-target")
crop_params = {};
target.attr("src",obj.src);
target.Jcrop({
onSelect: function(c){
crop_params = c;
}
});
});
Given the code above, the cropping works perfectly, but ONLY with the first image I try it on. When I click on the "cropper" icon for any other images after that, the first image is shown.
How can I work around this problem?
PS: I've searched through the already existing questions about Jcrop and couldn't find an answer to my particular problem.
You just need to create a new img tag and start jCrop with that.
$('#parent_tag #img_to_crop').remove();
$('#parent_tag').html('<img id="img_to_crop"></img>');
$('#parent_tag #img_to_crop').Jcrop({ options ... });
I am trying to find in the Galleria JavaScript file a place where I tell it to run a JavaScript function every time the current picture is changed (prev, next, or clicking on a thumbnail)
Does anyone with experience with galleria have any ideas?
http://galleria.io/
When you set up your Gallery bind to the image function and you will receive the event every time the image changes. I use it to load text into another area of my page like so.
Galleria.ready(function() {
this.bind("image", function(e) {
$("#text_div").text(arrayOfText[e.index]);
});
});
To make sure you have things setup correctly use it like this,
Galleria.loadTheme('galleria/themes/kscreates/galleria.classic.js');
Galleria.configure();
Galleria.ready(function() {
this.bind("image", function(e) {
console.log(e.index);
});
});
Galleria.run('#galleria');
and have a look in your Safari console and you will see the index of the currently displayed image.
Hope this helps.
my boss has me working on a website that basically has a very large gallery right in the middle.
The way this one part needs to work is that the user clicks a next/prev button, the image fades out, displays a loading spinning image gif, and then fades in with the new image when it's down downloading. I have no idea where to even begin.
I know jquery somewhat, but I'm very new to actual javascript. My only reference book at hand is a copy of "Javascript for Dummies" for 1997. Is this of any use to me at all, or has Javascript changed since then?
There are lots of jQuery plugin for image gallery: Galleria, GalleryView, Pikachoose, and this one.
Or you can search from jQuery plugins page.
Please get a newer book, or just use the web as a resource, any info. from 1997 is going to be horribly outdated.
This is a very simple site I've recommended to beginners before: http://htmldog.com/guides/javascript/
No, it doesn't cover everything, but that's what's good about it, you'll get some key things down, and then be able to search on google for more specific stuff.
To give you some barebones ot start with, I would do something like this:
$(document).ready(function() {
$('#nextBtn').click(function() {
transitionToNextImage ();
});
});
transitionToNextImage = function() {
$('img.active-image').fadeTo(1000,0), function() {
// fade out complete.
$('#inProgressGif').show();
getNextImage();
});
};
getNextImage = function() {
// make ajax call to get new image, and
// in the success callback of the ajax call,
// remove the inProgressGif, and
// add the image ot the DOM with opacity 0,
// then slowly fade it in to opacity 1 (opposite
// of what was done above
};
