I have a web application which is not relying on jquery.
I am doing functional tests thanks to (the great :) ) casperjs.
Now I would like to use jquery in my tests. So I tried to inject it as indicated here http://casperjs.org/faq.html#faq-jquery. Well, it's not working.
Here is my code if you can help me - is there something wrong? :
casper.start('http://localhost:8080/xxxxxx/xxxxxDialogTests.html');
casper.echo("page = " + casper.page); // -> it works, the page is there
casper.page.injectJs("../tools/jquery-1.7.2.js");
casper.waitFor(function check()
{
return this.visible('#button_create');
},
function then()
{
this.click('#button_create');
casper.waitFor(function check()
{
return this.visible('#dialog_document_name');
},
function then()
{
console.log("element : ", this.evaluate(function ()
{
var el = $("input#dialog_document_name");
return el;
}));
});
});
I removed the test as it is not the point...
thanks!
Try to add casper.options.clientScripts = ["../tools/jquery-1.7.2.js"] at the top of your test script.
Also try to set the absolute pass to the jQuery script, eg. /Users/foo/Work/project/tools/jquery-1.7.2.js.

My code is like this:
$('.flag-icon-dz').click(function() {
var lang = 'Arab';
var $frame = $('.goog-te-menu-frame:first');
if (!$frame.size()) {
console.log("Error: Could not find Google translate frame.");
return false;
}
$frame.contents().find('.goog-te-menu2-item span.text:contains(' + lang + ')').get(0).click();
$("li.ql-item.linkid188546").after("<li class='ql-item linkid18854777 closegoogle'><a href='#' class='btn-primary' target='_self'><i class='icon closegoogle ls-lang-frr' aria-hidden='true'></i></a></li>").fadeIn(500);
$('li.ql-item.linkid188546').fadeOut(500);
return false;
});
$('.closegoogle').click(function() {
$('.skiptranslate').contents().find('.goog-close-link > img').click();
$('li.ql-item.linkid18854777').fadeOut('fast').remove();
$('li.ql-item.linkid188546').fadeIn(500);
});
The first function works great, but the second doesn't. I realize that if I copy/paste the second function in the console after the first one, it works too.
I tried a few solutions (callback / setTimeout / jquery deferred / jquery .when method...) I didn't try promise but I don't think I have to in my context. Maybe I didn't write these solutions good enough.
I finally try to put my event (click) directly the .before() which create my new element like this :
$('.flag-icon-dz').click(function() {
var lang = 'Arab';
var $frame = $('.goog-te-menu-frame:first');
if (!$frame.size()) {
console.log("Error: Could not find Google translate frame.");
return false;
}
$frame.contents().find('.goog-te-menu2-item span.text:contains(' + lang + ')').get(0).click();
$("li.ql-item.linkid188546").after("<li class='ql-item linkid18854777 closegoogle'><a href='#' class='btn-primary' target='_self'><i class='icon closegoogle ls-lang-frr' aria-hidden='true'></i></a></li>").fadeIn(500).click(function() {
$('.skiptranslate').contents().find('.goog-close-link > img').click();
$('li.ql-item.linkid18854777').fadeOut('fast').remove();
$('li.ql-item.linkid188546').fadeIn(500);
});
$('li.ql-item.linkid188546').fadeOut(500);
return false;
});
But it doesn't work either.
Thanks for the help.
EDIT :
I finally found a kind of solution for my second click event (which isn't the best solution but i works) :
window.setInterval(function(){$('.closegoogle').on("click",function(){
$('.skiptranslate').contents().find('.goog-close-link > img').click();
$('li.ql-item.linkid18854777').fadeOut('fast').remove();
$('li.ql-item.linkid188546').fadeIn(500);
}); }, 1000);
Thanks.
You need to use a delegated bind as the element does not exist before you try your binding:
$('#parent-element-of-closegoogle').on('click', '.closegoogle', function() {
$('.skiptranslate').contents().find('.goog-close-link > img').click();
$('li.ql-item.linkid18854777').fadeOut('fast').remove();
$('li.ql-item.linkid188546').fadeIn(500);
});
Please note that the #parent-element-of-closegoogle needs to be an element that already exists when you do the binding - this can be $(document) if you hjave no other element to bind to
I have a javascript function that i have named refreshProjects(), what it does is filter a dropdownlist depending on what was selected in a previous dropdownlist. But i need to also filter my list direcktly after the page has finishd loading.
I have tried using the code window.onload = refreshProjects(id) with no sucsses, but onload workes when i use window.onload = alert('This page has finished loading!'), so i know that part off the script works. So how do i call a javascript function on load, i thought that it would be simple but evrything i tried have failed.
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
<script type="text/javascript">
window.onload = refreshProjects(id); <-- Problem
$("#ddCustomers").change(function () {
refreshProjects($(this).val());
});
function refreshProjects(id) {
var projects = $("#ddProjects");
$.get('#Url.Action("FilterProjects","TimeEntry")', { customerId: id },
function (result) {
// clear the dropdown
projects.empty();
//Add a deafult "null" value
$("#ddProjects").get(0).options[0] = new Option("[ - No project - ]", "-1");
// rebuild the dropdown
$.each(result, function (i, e) {
projects.append($('<option/>').text(e.Text).val(e.Value));
});
});
}</script>
}
This is for MVC 4.5.
Try changing window.onload = refreshProjects(id); to:
window.onload = function() { refreshProjects($("#ddCustomers").val()); };
Onload expects a callback function. You were directly executing refreshProjects() and setting the return value as the onload.
But since you seem to be using jQUery, you could do the following:
$(function() {
refreshProjects($("#ddCustomers").val());
});
This will execute refreshProjects when the document is ready (which actually is before window load).
You can also try to use the following:
$(document).ready(function () {
refreshProjects(id);
});
This should work aswell if you are using jQuery.
Let's say I have the following code:
$(function () {
$(".buy-it-now.ribbon").click(function () {
$(".bid-to-beat.ribbon.active").removeClass("active");
$(".bid-to-beat.ribbon").addClass("inactive");
$(".buy-it-now.ribbon.inactive").removeClass("inactive");
$(".buy-it-now.ribbon").addClass("active");
$(".bid-now").hide();
$(".buy-now").show();
$(".add-to-cart").hide();
})
$(".bid-to-beat.ribbon").click(function () {
$(".buy-it-now.ribbon.active").removeClass("active");
$(".buy-it-now.ribbon").addClass("inactive");
$(".bid-to-beat.ribbon").removeClass("inactive");
$(".bid-to-beat.ribbon").addClass("active");
$(".buy-now").hide();
$(".bid-now").show();
$(".add-to-cart").show();
});
});
It is a simple function that allows for multiple UI related things to happen on the front-end of a site I am working on. I am fairly (very) new to jQuery and JavaScript in general and am learning about refactoring and making my code more condensed now. The way I currently write code is sort of line per thought I have. So my question is how would an experienced developer write this same code? Or rather, how could I refactor this code?
Try the following:
$(function () {
var $handlers = $('.buy-it-now.ribbon, .bid-to-beat.ribbon');
$handlers.click(function() {
$handlers.toggleClass("active inactive");
var $elements = $(".bid-now, .add-to-cart"),
$buyElement = $(".buy-now");
if($(this).is('.buy-it-now.ribbon')) {
$elements.hide();
$buyElement.show();
} else {
$elements.show();
$buyElement.hide();
}
});
});
This question would be better suited for codereview, but yes it can be condensed a little using method chaining.
$(function () {
$(".buy-it-now.ribbon").click(function () {
$(".bid-to-beat.ribbon").removeClass("active").addClass("inactive");
$(".buy-it-now.ribbon").removeClass("inactive").addClass("active");
$(".bid-now").hide();
$(".buy-now").show();
$(".add-to-cart").hide();
})
$(".bid-to-beat.ribbon").click(function () {
$(".buy-it-now.ribbon").removeClass("active").addClass("inactive");
$(".bid-to-beat.ribbon").removeClass("inactive").addClass("active");
$(".buy-now").hide();
$(".bid-now").show();
$(".add-to-cart").show();
});
});
You could condense it further by pre selecting the elements and caching them in variables before the click events as long as no elements are added or removed during the life of the page.
As your code it is you can combine some of the selectors into a single line. And also because your elements looks to be static you can cache them into a variable and use them later as it reduces the number of times a element is looked up in the DOM reducing the accessing time..
Also you can limit the scope of these variables or selectors by encasing them in an object or a closure..
Maybe something in these lines..
$(function () {
cart.init();
});
var cart = {
elems : {
$buyRibbon : null,
$bidRibbon : null,
$bidNow: null,
$buyNow: null,
$addToCart: null
},
events : {
},
init : function() {
this.elems.$buyRibbon = $(".buy-it-now.ribbon");
this.elems.$bidRibbon = $(".bid-to-beat.ribbon");
this.elems.$bidNow = $(".bid-now") ;
this.elems.$buyNow = $(".buy-now") ;
this.elems.$addToCart = $(".add-to-cart") ;
this.events.buyClick();
this.events.bidClick();
}
};
cart.events.buyClick = function() {
cart.elems.$buyRibbon.on('click', function(){
cart.elems.$bidRibbon.removeClass('active').addClass('inactive');
cart.elems.$buyRibbon.removeClass('inactive').addClass('active');
cart.elems.$bidNow.hide();
cart.elems.$buyNow.show();
cart.elems.$addToCart.hide();
});
}
cart.events.bidClick = function() {
cart.elems.$bidRibbon.on('click', function(){
cart.elems.$buyRibbon.removeClass('active').addClass('inactive');
cart.elems.$bidRibbon.removeClass('inactive').addClass('active');
cart.elems.$bidNow.show();
cart.elems.$buyNow.hide();
cart.elems.$addToCart.show();
});
}
So basically in here your whole cart is a object ..And the cart has different properties which are related to this.. You follow the principles of object oriented programming here..
Using closures I heard gives you better design limiting the scope of your code..
Might I suggest something like this:
$(function () {
var buyNowButton = $('buy-it-now.ribbon'),
bidToBeatButton = $('.bid-to-beat.ribbon'),
buyNowEls = $('.buy-now'),
bidToBeatEls = $('.bid-now,.add-to-cart');
var toggleButtons = function(showBuyNow){
buyNowButton.toggleClass('active', showBuyNow);
bidToBeatButton.toggleClass('active', !showBuyNow);
buyNowEls.toggle(showBuyNow);
bidToBeatEls.toggle(!showBuyNow);
}
buyNowButton.click(function(){ toggleButtons(true) });
bidToBeatButton.click(function(){ toggleButtons(false) });
});
You could save a some lines by removing the selectors at the start and just do the selection in place, if the saved space would be more important than the minor performance hit. Then it would look like this:
$(function () {
var toggleButtons = function(showBuyNow){
$('buy-it-now.ribbon').toggleClass('active', showBuyNow);
$('.bid-to-beat.ribbon').toggleClass('active', !showBuyNow);
$('.buy-now').toggle(showBuyNow);
$('.bid-now,.add-to-cart').toggle(!showBuyNow);
}
$('buy-it-now.ribbon').click(function(){ toggleButtons(true) });
$('.bid-to-beat.ribbon').click(function(){ toggleButtons(false) });
});
The first version selects the elements once and holds them in memory; the second selects them each time the button is clicked. Both solve the problem I believe would occur with the selected answer where clicking the same button twice would cause the .active and .inactive classes to get out of sync with the shown/hidden elements.
I'm trying to something like this if in the html there is a div called "#super" load it in the simple modal if not do nothing. I managed to do this with the my skill :D which is none: to load the modal if the #super exists, but it still loads doesn't matter if it exitst or not. PLease help I'm absolute noob on jquery.
if( $('super') ){ $("#super").modal({onOpen: function (dialog) {
dialog.overlay.fadeIn('slow', function () {
dialog.container.slideDown('slow', function () {
dialog.data.fadeIn('slow');
});
});
}});
I'm using this jquery plugin link text
If #super does not exist, nothing will happen. So, the following should fit your needs:
$("#super").modal({onOpen: function (dialog) {
dialog.overlay.fadeIn('slow', function () {
dialog.container.slideDown('slow', function () {
dialog.data.fadeIn('slow');
});
});
});
I'm not quite sure what it is that you want to do, in the if/else conditions, but to test for the existence of something:
if ($('#super').length) {
// it exists, do stuff
}
else {
// it doesn't exist, do other stuff. Or nothing
}
I'm sorry I can't be more specific, but I've not worked with the dialog/modal plugin.
The problem is this check
if( $('#super') )
will always return true, since the jQuery function always return a jQuery object which is not a false value.
Instead try this
if( $('#super').length > 0 )
I'm not an expert of jquery and i need help to porting this function
auto_complete: function(controller, focus) {
if (this.autocompleter) {
Event.stopObserving(this.autocompleter.element);
delete this.autocompleter;
}
this.autocompleter = new Ajax.Autocompleter("auto_complete_query", "auto_complete_dropdown", "/admin/" + controller + "/auto_complete", {
frequency: 0.25,
afterUpdateElement: function(text, el) {
if (el.id) {
window.location.href = "/admin/" + controller + "/" + escape(el.id);
} else {
$("auto_complete_query").value = "";
window.location.href = window.location.href;
}
}
});
$("auto_complete_dropdown").update("");
$("auto_complete_query").value = "";
if (focus)
$("auto_complete_query").focus();
},
Anyone may help me?
Although that uses some Prototype calls, that's actually mostly just using a script.aculo.us auto-completer; you'll want to find a similar widget for jQuery (there's one listed on the jQuery plug-ins page) and then rewrite the code to do the same thing using that plug-in. Looks like mostly what it does is navigate to "/admin/mumble/id" where "mumble" is the value of the pass-in controller variable and "id" is the ID of the element chosen in the auto-completer.
