GwtQuery - fadeIn one after another - gwt

I want to add fade-in animation for couple of widgets one after another.
I reviewed the doc, but it only does first fade-in.
$(myWidget1).fadeIn(new Function(){
public boolean f(Event e){
//tried to add the second fade-in for myWidget2, but no result
return true;
}
});
How do I achieve fade-in one after another in this way or, is there another way to do it?
Thanks!

Try this, using jQuery:
$(document).ready(function(){
var widgets = $('.widget');
var fader = function(widget_n){
if (widget_n < widgets.length) {
$(widgets.get(widget_n)).fadeIn('slow', function(){
fader(widget_n +1);
});
}
};
if (widgets.length > 0) {
fader(0);
}
});

Check my example here : http://gwtquery-plugins.googlecode.com/svn/branches/droppable_1_0/demo/DraughtsSample/DraughtsSample.html
I use the fadeIn GQuery method method to fade in each piece of the board. You can find the code there : http://code.google.com/p/gwtquery-plugins/source/browse/trunk/droppable/sample/src/main/java/gwtquery/plugins/droppable/client/draughtssample/CheckerBoard.java#116

Why dont you use the .each() function to loop through your "widgets".
var map = {
'mywidget1': '#mywidget1',
'mywidget2': '#mywidget2'
};
$.each(map, function(key, value) {
$(value).fadeIn(...);
});
or if they all have a something in common (i.e. class of tag combination etc.) this would be even easier.
See .each() jQuery API

You are overriding an incorrect method: f(Event) is used for events, change it by f():
$(myWidget1).fadeIn(new Function(){
public void f() {
$(myOtherWidget).fadeIn();
}
});

Ionic slides update() function

I am generating ion-slides asynchronously. However I believe I need to use update() function.
Below is the api section: https://ionicframework.com/docs/api/components/slides/Slides/#update
I am not sure how to use this function.
Could someone show me how to use this function?
Thanks!
this is how i did it in a past project:
first you have to get the instance of your slide:
$scope.$on("$ionicSlides.sliderInitialized", function(event, data){
//self is my controller
self.sliderInstance = data.slider;
//slidesLoaded is a custom var i used to store loaded slides
if(self.slidesLoaded.length < 1){
//initialisation stuff, or filling content
//...
self.sliderInstance.update();
}
});
then you can call it anytime you add a slide for example, in my case i did a dynamic next slide loading:
$scope.$on("$ionicSlides.slideChangeEnd", function(event, data){
var index_t = self.sliderInstance.activeIndex;
self.loadSlide(index_t + 1);
self.sliderInstance.update();
});

Protractor how to wait for options

I have code like this:
element(by.model("roleSelection.role")).element(by.cssContainingText('option', newRole)).click();//.then(function() {console.log('role click')})//;
where the options is loaded via a call to the server.
I can wait for the first element by doing this
browser.wait(function() {
return browser.isElementPresent(by.model("roleSelection.role")).then(function(present){
return present;
});}, 8000);
and it seems to work. But how can I wait until the "sub-element" is clickable.
I have tried this
browser.wait(function() {
return browser.isElementPresent(by.model("roleSelection.role")).then(function(present){
if (present) {
var elm = element(by.model("roleSelection.role"));
return elm.isElementPresent(by.cssContainingText('option', newRole)).then(function(subpresent) {
return subpresent;
});
}
}); }, 8000);
Have you tried clickable? Something along these lines
var EC = protractor.ExpectedConditions;
var select = element(by.model("roleSelection.role"))
var isClickable = EC.elementToBeClickable(select);
browser.wait(isClickable,5000); //now options should have been loaded by now
Well, try to this: https://angular.github.io/protractor/#/api?view=ExpectedConditions.prototype.elementToBeClickable
But, Please keep in mind, Protractor is suitable for angular webpages and interactions, and animations. For example ng-animate. So, it is not sure to working for example jquery, or other animates.
In this way:
onPrepare: function () {
// disable animations when testing to speed things up
var disableNgAnimate = function () {
angular.module('disableNgAnimate', []).run(function ($animate) {
$animate.enabled(false);
});
};
browser.addMockModule('disableNgAnimate', disableNgAnimate);
}
Or you can switch in script way in browser.executeScript().
Please see this link. It works only jquery animations.
If you not have animate problems. Use setTimeout() JS function.

infinite scroll manual trigger callback

I'm using Infinite Scroll plugin in a (I know it is unrecommended http://isotope.metafizzy.co/docs/help.html#infinite_scroll_with_filtering_or_sorting), Infinite Scroll + Isotipe Filtering combination.
Now sometimes happend that after i run my filter, if I get an empty list i manually trigger infinite scroll to load more elements.
$('.items').isotope({ filter: filter }, function( $items ) {
var id = this.attr('class'),
len = $items.length;
if (len == 0){getElement();}
});
Here is my function that load elements, but it seems that the callback is not working.
function getElement(){
$('.items').infinitescroll('retrieve',function(items){
console.log('callback');
console.log(items);
});
}
Unfortunally Infinite Scroll documentation is not the best for manual trigger (it suggest a not-working way to call it - $(document).trigger('retrieve.infscr'); i found the solution here: infinite scroll manual trigger) so I'm a little bit stucked here.
Any suggestion?
I know it is a very old post. But I find it over Google as I searched for the self problem. But I also find the solution for this. Perhaps it helps somebody...
You must put the callback not to the main function. Because manual function only push the main function.
jQuery(document).ready(function($) {
var $infinitecontainer = $(".infinite-content").infinitescroll({
navSelector: ".nav-links",
nextSelector: ".nav-links a:first",
itemSelector: ".infinite-post",
errorCallback: function(){ $(".inf-more-but").css("display", "none") }
}, function() { // callback
alert("Manual click load finished");
});
$(window).unbind(".infscr");
$(".inf-more-but").click(function(e){
e.preventDefault();
var infinite_scroll = $(".infinite-content").infinitescroll("retrieve");
return false;
});

jQuery get object moused over

I have this code:
$('*').mouseover(function() {
$('#log').text($('*').id);
});
When you mouse over any element on the page, I want #log to have the id of that element. Obviously the code above doesn't work... How do I do this?
$('*').mouseover(function() {
console.log($(this).attr('id'))
});
In almost all jQuery callbacks, "this" is the object on which the callback is being executed.
$('*').mouseover(function() {
$('#log').text($(this).attr('id'));
});
You can also use event.target
var $log = $("#log");
$('*').mouseover(function(event) {
$log.text($(event.target).attr('id'));
event.stopPropagation();
});

jquery selection with .not()

I have some troubles with jQuery.
I have a set of Divs with .square classes. Only one of them is supposed to have an .active class. This .active class may be activated/de-activated onClick.
Here is my code :
jQuery().ready(function() {
$(".square").not(".active").click(function() {
//initialize
$('.square').removeClass('active');
//activation
$(this).addClass('active');
// some action here...
});
$('.square.active').click(function() {
$(this).removeClass('active');
});
});
My problem is that the first function si called, even if I click on an active .square, as if the selector was not working. In fact, this seems to be due to the addClass('active') line...
Would you have an idea how to fix this ?
Thanks
Just to give something different from the other answers. Lonesomeday is correct in saying the function is bound to whatever they are at the start. This doesn't change.
The following code uses the live method of jQuery to keep on top of things. Live will always handle whatever the selector is referencing so it continually updates if you change your class. You can also dynamically add new divs with the square class and they will automatically have the handler too.
$(".square:not(.active)").live('click', function() {
$('.square').removeClass('active');
$(this).addClass('active');
});
$('.square.active').live('click', function() {
$(this).removeClass('active');
});
Example working: http://jsfiddle.net/jonathon/mxY3Y/
Note: I'm not saying this is how I would do it (depends exactly on your requirement) but it is just another way to look at things.
This is because the function is bound to elements that don't have the active class when you create them. You should bind to all .square elements and take differing actions depending on whether the element has the class active:
$(document).ready(function(){
$('.square').click(function(){
var clicked = $(this);
if (clicked.hasClass('active')) {
clicked.removeClass('active');
} else {
$('.square').removeClass('active');
clicked.addClass('active');
}
});
});
