my html looks like this
<form class="form-horizontal" role="form">
<div class="form-group">
<ul class="select_list">
<li>Apple</li>
<li>Peach</li>
<li>Plum</li>
<li>Banana</li>
<li>Grapes</li>
<li>Pear</li>
<li>Kiwi</li>
</ul>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
and my jQuery is like this:
$(".select_list li").on('click',function(){
$(this).toggleClass("chosen");
}
this works, it adds a class if the list item is clicked but i want to prevent more than 3 from being selected. How can I do this? also if 3 are selected the other ones should fade out. The user should be able to unselect one of three and see the unselected ones again like before. how would I do this? I need to get number selected but i don't know how
thanks in advance
You would use $('.select_list li.chosen').length to access the number of selected elements. Check to see if the clicked element has the class chosen in order to ensure that it can be unselected.
EXAMPLE HERE
$(".select_list li").on('click',function(){
if($('.select_list li.chosen').length < 3 || $(this).hasClass('chosen')){
$(this).toggleClass('chosen');
}
});
For the fading part, just use fadeIn/fadeOut on the sibling elements based on the number of chosen elements.
UPDATED EXAMPLE HERE
$(".select_list li").on('click',function(){
if($('.select_list li.chosen').length < 3 || $(this).hasClass('chosen')){
$(this).toggleClass('chosen');
var chosen = $('.select_list li.chosen');
var notChosen = $(this).siblings();
if(chosen.length == 3){
$(notChosen).not(chosen).fadeOut();
} else {
$(notChosen).fadeIn();
}
}
});

In my node app using express I have a view function that creates a list of inactive companies, each company has two submit input types "Active" and "Delete". I would like to be able to hit submit and have that individual ul become hidden. However, I'm not quite sure how to iterate over individually. Every time I've tried I end up hiding all the elements. Here's my view function:
function inactiveFiltered(companyObject) {
return `
<ul class="companyinfo">
<li class="list-info">${companyObject.company_type}</li>
<li class="list-info">${companyObject.company_name}</li>
<li class="list-info">${companyObject.company_location}</li>
<li class="list-info">${companyObject.company_phone}</li>
<br>
<li class="list-buttons">
<form action="/activeList" method="POST" class="myform">
<input type="hidden" name="companyId" value="${companyObject.id}">
<input type="submit" value="Active">
</form>
<form action="/deletecompany" method="POST">
<input type="hidden" name="companyId" value="${companyObject.id}">
<input type="submit" value="Delete">
</form>
</li>
<br>
</ul>
`
}
function inactiveList(arrayOfCompanies){
const companyItems = arrayOfCompanies.map(inactiveFiltered).join('');
return `
<div class="list inactive-list">
${companyItems}
</div>
`
}
module.exports = inactiveList;
One function takes an array of companies and then creates an company object. Now here's the latest JQuery attempt, but like I said it hides all the ul elements:
$(document.body).submit(function() {
$('.companyinfo').each(function(i) {
$(this).hide();
})
})
I've been stuck on this for waaay too long and would love any help whatsoever. Thank you!
You are hiding all elements at the same time because the selector .companyinfo returns a list of all elements using the class companyinfo which are all companies in your case. That's why they get hidden all at the same time
One way to achieve your goal is to add ids to the ul elements to be able to address them for each company individually like so: <ul id="companyinfo_${companyObject.company_name}" class="companyinfo">.
Then add a method hideCompany() to replace the $(document.body).submit(function() part:
function hideCompany(companyname) {
$('#companyinfo_' + companyname).hide();
}
Finally, modify <input type="submit" value="Delete">to read <input type="submit" value="Delete" onclick="hideCompany('${companyObject.company_name}')">.
HTML code
<div class="check-box-panel">
<!--
ngRepeat: employee in employees
-->
<div class="ng-scope" ng-repeat="employee in employees">
<div class="action-checkbox ng-binding">
<input id="John" type="checkbox" ng-click="toggleSelection(employee.name)"
ng-checked="selection.indexOf(employee.name) > -1" value="John"></input>
<label for="John">
::before
</label>
<!--
John
end ngRepeat: employee in employees
-->
<div class="ng-scope" ng-repeat="employee in employees">
<div class="action-checkbox ng-binding">
<input id="Jessie" type="checkbox" ng-click="toggleSelection(employee.name)"
ng-checked="selection.indexOf(employee.name) > -1" value="Jessie"></input>
<label for="Jessie"></label>
I tried using jQuery
element(by.repeater('employee in employees')).element(by.id('Jessie')).click();
also,I tried using css
element(by.repeater('employee in employees')).$('[value="Jessie"]').click();
But it didn't do the job. Any other way I can click on the particular Checkbox?
Alright I had a very similar issue where I couldn't click the checkbox. It turned out I had to click the checkbox label. However if you want to do any checks on if the checkbox is selected then you have to check the actual checkbox. I ended up making two variables, one for the label and one for the actual checkbox.
JessieChkbxLabel = element(by.css("label[for='Jessie']"));
JohnChkbxLabel = element(by.css("label[for='John']"));
//Click the Jessie checkbox
JessieChkbxLabel.click();
//Click the John checkbox
JohnChkbxLabel.click();
You should just need to use element(by.id('Jessie')) to grab your object. The issue you might be having is that click() returns a promise, so you need to handle that with a .then. So something along the lines of:
element(by.id('Jessie')).click().then(function(value) {
// fulfillment
}, function(reason) {
// rejection
});
Aside from checking the id directly, you can also filter the desired element checking the employee name:
var employee = element.all(by.repeater('employee in employees')).filter(function (elm) {
return elm.evaluate("employee.name").then(function (name) {
return name === "Jessie";
});
}).first();
employee.element(by.css("input[type=checkbox]")).click();
I have this code http://codepen.io/anon/pen/JdNdXd which lets me pick wheels, tiers etc. The thing I want to do is when I get to the last div, where the description of an items is displayed, I have a button and I want to make it when that button is clicked its text is added in the bellow div called Cart, this works as a shoping cart. If you pick Farovi then Original and then Devil eyes you can see that you get text with product name, its code and price, the second line has a button, so I want when I press that button that item gets added to the cart in the div bellow. Is this possible and how can I delte one of products from shopping cart if I want.
Tried a few diferent codes but could not to get it working, last one I tried is append function but could not get it working. This bellow is just example of append function, I did not use this one in my code
$( ".container" ).append( $( "h2" ) );
Try this way:
Form your HTML like this:
<div class="col-md-2">
<ul class="nav nav-pills nav-stacked" id="menu">
<li>Felge
</li>
<li>Gume
</li>
<li>Branici
</li>
<li>Farovi
</li>
</ul>
</div>
<div id="cart"></div>
And JavaScript like this:
function addToCart(item) {
var cart = document.getElementById("cart");
$("#cart").append("<p><a class='cartitem' href='#' onclick='removeFromCart(this)'>" + item.innerHTML + "</a></p>");
$('.cartitem').click(function (e) {
$(e.target).remove();
});
}
function removeFromCart(ele) {
$("#cart").remove(ele);
}
$(function () {
$('.item').click(function () {
addToCart(this);
});
});

I have a dynamically created 3 options list which are attached at the end of a table row. I want to hide or disable Edit and Copy options if certain conditions are not met when page loads. How can i do this using either jQuery of JavaScript.
<div class="btn-group ewButtonGroup open">
<button class="dropdown-toggle btn btn-small" data-toggle="dropdown" href="#">Options <b class="caret"></b></button>
<ul class="dropdown-menu ewMenu">
<li><a class="ewRowLink ewView" data-caption="View" href="teamsview.php?showdetail=&TeamID=1">View</a></li>
<li><a class="ewRowLink ewEdit" data-caption="Edit" href="teamsedit.php?TeamID=1">Edit</a></li>
<li><a class="ewRowLink ewCopy" data-caption="Copy" href="teamsadd.php?TeamID=1">Copy</a>
</li>
</ul>
</div>
I have tried the following code which deosnt work.
<script>
$(document).ready(function() {
var Week_Check = $('#ewRowLink ewView span').text();
if ( Week_Check > 10) {
$('.ewRowLink ewView').hide();
}
});
</script>
You have a bad jQuery selector. If you want to hide an element having both of those classes you want to go this way:
$('.ewRowLink.ewView').hide();
By using $('.ewRowLink ewView').hide(); you basically state: hide all ewView (?) elements that are inside other elements having ewRowLink class.
You can use .off() to unbind the event:
$('.ewEdit, .ewCopy').off('click');
or if you want to hide:
$('.ewEdit, .ewCopy').hide();
Yet you need to mention on what condition you want to do this.
<script>
$(document).ready(function() {
var Week_Check = $('#ewRowLink, #ewView').find('span').html();
if ( Week_Check > 10) {
$('.ewRowLink, .ewView').hide();
}
});
</script>
I am designing a simple jquery live search function within a widget on a site i'm developing. I have borrowed some code I found and it is working great. The problem is though that instead of using a list like this:
<ul>
<li>Searchable Item 1</li>
<li>Searchable Item 2</li>
etc
I am using a list like this:
<ul>
<li>
<a href="#">
<div class="something>
<img src="something.jpg">
<p>Searchable Item 1</p>
</div>
</a>
</li>
etc.
As you can see the text I want to search is in the p tag. The functions I have used are searching all the other stuff (a href, div, img) and matching text found in those tags as well as the item within the p tag. Sorry if my explanation is a bit confusing but I will show you an example of the code here:
//includes im using
<script type="text/javascript" src="js/jquery-1.7.min.js" ></script>
<script type="text/javascript" src="js/quicksilver.js"></script>
<script type="text/javascript" src="js/jquery.livesearch.js"></script>
//document ready function
$(document).ready(function() {
$('#q').liveUpdate('#share_list').fo…
});
//actual search text input field
<input class="textInput" name="q" id="q" type="text" />
//part of the <ul> that is being searched
<ul id="share_list">
<li>
<a href="#">
<div class="element"><img src="images/social/propellercom_icon.jpg… />
<p>propeller</p>
</div>
</a>
</li>
<li>
<a href="#">
<div class="element"><img src="images/social/diggcom_icon.jpg" />
<p>Digg</p>
</div>
</a>
</li>
<li>
<a href="#">
<div class="element"><img src="images/social/delicios_icon.jpg" />
<p>delicious</p>
</div>
</a>
</li>
</ul>
also here is the jquery.livesearch.js file I am using
jQuery.fn.liveUpdate = function(list){
list = jQuery(list);
if ( list.length ) {
var rows = list.children('li'),
cache = rows.map(function(){
return this.innerHTML.toLowerCase();
});
this
.keyup(filter).keyup()
.parents('form').submit(function(){
return false;
});
}
return this;
function filter(){
var term = jQuery.trim( jQuery(this).val().toLowerCase() ), scores = [];
if ( !term ) {
rows.show();
} else {
rows.hide();
cache.each(function(i){
var score = this.score(term);
if (score > 0) { scores.push([score, i]); }
});
jQuery.each(scores.sort(function(a, b){return b[0] - a[0];}), function(){
jQuery(rows[ this[1] ]).show();
});
}
}
};
I believe the problem lies here:
var rows = list.children('li'),
cache = rows.map(function(){
return this.innerHTML.toLowerCase();
});
it is just using whatever it finds between the li tags as the search term to compare against the string entered into the text input field. The search function actually does work but seems to find too many matches and is not specific as I am also using a quicksilver.js search function that matches terms that are similar according to a score. When I delete all the other stuff from the li list (a href, img, div, etc) the search function works perfectly. If anyone has any solution to this I would be really greatful, I have tried things like:
return this.children('p').innerHTML but it doesn't work, I'm ok with PHP, C++, C# etc but totally useless with javascript and Jquery, they're like foreign languages to me!
In the jquery.livesearch.js file I believe you can replace this line:
var rows = list.children('li'),
with:
var rows = list.children('li').find('p'),
This should make it so the livesearch plugin will only search the paragraph tags in your list.
You will need to change the .show()/.hide() lines to reflect that you are trying to show the parent <li> elements since you are now selecting the child <p> elements:
Change:
rows.show();//1
rows.hide();//2
jQuery(rows[ this[1] ]).show();//3
To:
rows.parents('li:first').show();//1
rows.parents('li:first').hide();//2
jQuery(rows[ this[1] ]).parents('li').show();//3
