So I got an div called cart. JavaScript adds there div's each clicked item on page. So example: Website has Banana, Apple, Car. Then itemcart is empty, if person clicks on Banana then javascript adds <div class=banana>Banana</div>
Then you can click button Purchase which calls function purchase(). I want to add there that, if purchase() function called, then in that it will get content of that itemcart and get all items what are there and display them in sweetalert. Is that possible?
var itemcurt = $("#itemcart");
I tried that, but it just shows Object object..
$("#itemcart") is a object you want its inner content so you may use
var itemcurt = $("#itemcart").text();
.text() will give the inner content in text form even if there are some tags in it then also everything will come in text
For example
<div id="itemcart">
<div>text</div>
</div>
In above html if you use .text() then the div inside it will come in text form like this <div>text</div>
If in case you have html tags inside it and want in html form then use this
var itemcurt = $("#itemcart").html();

I am working on an ecommerce site, I have a page that shows the products grid. There are two button side by side. One contains link to the post and other opens a dialogue box with textarea inside. (see picture)
Image 1
Image 2
Now, what I want is when I click the GETLINK BUTTON button it must take the href attribute of the VIEW BUTTON and populate in the textarea. But what I get in the link of 1st product only even if I click the other Get Link Buttons.
Here's the JS code:
function opengetlink(){
var sacprodlink = document.getElementById("sac_prod_link").href;
jQuery("#sac_link_text").html(sacprodlink);
}
Help would be appreciated, thanks in advance.
EDIT: Solved
$(".open").click(function() {
var link = $(this).closest('div.viewbutton').find('a.btn-link').attr('href');
$("#link_text").html(link);
});
Ids are given to HTML elements to make them unique. Since you have many elements of the same kind and want to perform the same operation on each of them, you should use classes. Give your View and Get Link buttons a class.
$(".sac_open_link").click(function() {
var link = $(this).siblings(".sac_prod_link").href;
$(this).html(link);
});
At first I apologize for not having the code of my desire & I've no idea how I'll ask the exact question by focusing any specific keywords.
However, I want to show my product information in an area(div) whenever I click a button in another area(div). & The work should be done without refreshing pages.
Again I apologize for that I've not the code. But I can provide an
image and hope you'll understand my desire
Example: Whenever I click on angry burger, the price and quantity should be shown in the right(California Fried Chicken) area. And multiple selecting product should also work one by one. After that I should be able to submit product information bu pressing submit button where a PHP operation should be done.
I want to do the whole task by jQuery & PHP
Thanks
You can achieve this by setting up click listeners in your javascript/jquery code and assign them to the ids of your pictures or fields. For example you can assign an id to an tag like below;
<p id="div">Hello world</p>
And then set up a click event in your jquery code to execute a function whenever that tag is clicked
$( "#div" ).bind( "click", function() {
var tag = $(this).html(); //get the value of the tag
alert(tag);//this will display Hello world
});
You can do this for any tag and retrieve its value or contents or anything and carry out an activity like changing the display of another element as below
$("#change").append(tag) //this will change the display of the tag with id change
Please ask if you have any questions
Let's say that I'm building something like order cart.
I have one main page, and a lot of subpages.
On the subpages I have some specified product which user can add to the order by clicking on the button.
If the user click the button, javascript is called grabbing the name of the product and sending it AJAX to some PHP file which add this product name to some $_SESSION array.
If there's atleast one product in the cart, the FIXED div on the bottom of the screen appear. This div runs modal (bootstrap) and it contains all of the products which user had add to the order. Again I'm using here javascript + AJAX to determine click. If it's, there is a call to .php file which return STRING contains all the products. Then, this string is appended to the div inside this modal.
Content of this modal looks like:
'name_of_the_product', 'delete', 'id_from_session_array'
...
...
So I want allow the user to use DELETE option for any of his products in this list if he no longer want this product in the cart. I wrapped the delete text in some anchor and gave it class - let's say '.delete_from_cart'.
And now, when I'm trying to check in javascript if this element ('.delete_from_cart') has been clicked, nothing happens.
Sample code for this looks like:
$('.delete_from_cart').click(function() {
alert("foo");
});
No alert at all after clicking some .delete_from_cart div. However, in the code source all of this anchors has this class.
How to fix that? It seems like javascript doesnt see appended elements from ajax in this div. Any help?
since you said that your modal is generated using an Ajax call, you will not be able to attach the click event to the element. You will need to use jQuerys on() method to bind the onclick.
$("#themodal").on( "click", ".delete_from_cart", function(){
alert('it worked');
});
See on() method more details.

Apologies for the long question, but I've tried a lot of things and done some research and havent found much of a solution. I have a content editable div.
<div contentEditable=true onkeyup='showResult(this.lastChild.textContent)'></div>
When a user types something into this div, the showResult javascript runs which is basically an ajax request which returns a list of items that match. When a user clicks on one of the suggestions, say the name "John", a span with the suggestion is added into this contentEditable div like so:
<div contentEditable=true onkeyup='showResult(this.lastChild.textContent)'>
<span id='uniqueId1' class='SpanClass' contentEditable='false'>John</span>
</div>
Having selected one Name, the user may want to search for another name. It HTML terms, that means that they would be typing the following:
<div contentEditable=true onkeyup='showResult(this.lastChild.textContent)'>
<span id='uniqueId1' class='SpanClass' contentEditable='false'>John</span>
New User Text Goes Here
</div>
On Chrome, the right behaviour happens when the user continues tries typing in the div - the showResult function runs on the new text that the user types in and ignores the span elements. For Example, if the user types in "Fr" having already selected John, it ignores the first children (John), and sends what the user typed off via ajax and returns suggestions like Fred and Frankie.
However, in IE the span is still content editable and the user can't add any text other than within the span, which seems to make no sense as it is clearly contentEditable=false The ajax request is therefore run on the "John" text plus whatever the user types in next, which is not what I'm trying to achieve.
Finally, in Firefox, the span is not contentEditable BUT the lastChild bit only picks up text within the span, and ignores the text the user puts in.
I've console logged the results of showResult(this.lastChild.textContent) to see what is being sent to the ajax request.
In Chrome, typing in "Fr" in the box after the "John" span sends "Fr" to the ajax and returns the right result.
In IE, typing in "Fr" in the box sends "JohnFr"
In Firefox, typing in "Fr" just sends "John".
As the issue is with this lastChild and the span, I've also included the Javascript that creates the span element. This only activates after a successful result is return and the result is clicked on. (please excuse the very messy Javascript/Jquery)
$('body').on("click", '.TagHints', function(){
//Once you click on the suggestion
var ThisData = $(this).data("id");
var ThisId = $(this).attr("id");
var ThisTag = $(this).data("tag");
//delete the text that the user typed in
elementToRemove = document.getElementById("FakeInput").lastChild;
document.getElementById("FakeInput").removeChild(elementToRemove);
var TagDiv = document.createElement('span');
TagDiv.className = 'SpanClass';
TagDiv.id = ThisId;
TagDiv.innerHTML = ThisTag;
TagDiv.contentEditable=false;
//append the Span to the contentEditable div
document.getElementById("FakeInput").appendChild(TagDiv);
var TagHints = document.getElementsByClassName("TagHints");
while(TagHints.length > 0){
TagHints[0].parentNode.removeChild(TagHints[0]);
}
});
Why are the three browsers behaving completely differently and how do I get them all to behave like Chrome is? Is there a better way of getting the text not in the spans?
I read on another answer that firefox likes inputs and IE likes breaks in this context but both do not seem to work for me. :-(.
One big stopper to good solutions is that jQuery stops working after about line 6, which has also completely baffled me. If anyone can explain why its not working, that would also be cool. Maybe something to do with it being an ajax query and content being created after jquery is loaded?
Thanks for your help!
So, although I haven't had any responses I've come up with a workaround. However, lastChild is still behaving differently between the three browsers so would appreciate any further input.
The answer was to have a function in the document ready section which cloned the original div, stripped it of its children and grabbed the text on key up using Jquery. This then passed the result to the showResult function like so:
$('#FakeInput').keyup(function(){
var ThisClone = $('#FakeInput').clone()
.children()
.remove()
.end()
.text();
showResult(ThisClone);
});
Equally, rather than trying to remove the text that the user typed in from the divs when the user makes a selection I simply cloned the items in the span, using their class, then emptied the contents of the div and reappended these cloned divs.
var TagItems = $('.TagItems').clone();
$('#FakeInput').empty();
$('#FakeInput').append(TagItems);
This solution works across the three browsers.
My html page has a list of people's names, with a button at the bottom that says 'Add new'. On clicking this button, a pop up page opens. This page has a form to collect a new name. I want to add this name to the original list. This is my javascript which works perfectly to append a list on the same page as the text box:
<script>
$('#add').click(function(){
var text = $('#input').val();
if (text.length){
$('ul.list-group').append('<li class="list-group-item">' +text+'</li>');
}
});
</script>
How can I edit it so that it appends the list on the original page?
What type of popup do you use ? With a classical popup (ie a "new page"), you can't do this with Javascript because it requires server-side treatment (Javascript is only for client, and so can only play with the current page DOM)
However, you can use something like Bootstrap Modal, that is just a "popup-like" append to the DOM ; then you can easily modify your first list. ;)
