I have a number of divs floating in several rows. The divs contain text-previews and a link to slide down the full content (see http://jsfiddle.net/yDcKu/ for an example).
What happens now: When you slide down the content-div it opens right after the connected preview.
What I want to happen: Open the content-div after the last div in the row.
I assume the could be done by:
1. find out which div is the last one in the row of the activated preview,
2. add an id to this div and
3. append the content-div to this div.
I have a solution for steps 2 und 3 using jQuery but no guess how to do the first step.
I can manage to get the document width and the x- and y-value of each div but I have no idea how to find out which div has the highest x- as well the highest y-value and as well is in the row of the activated preview-div.
Any idea anyone? Thanks
Here is an example that does what you want. I simplified your code, so you don't have to manually ID every entry and preview.
http://jsfiddle.net/jqmPc/1/
It's a little complicated. Let me know if you have questions.
Basically, when the window is resized, the script goes through and finds the first preview in each row by finding the preview with the same left offset as the very first one. It then adds a class last to the entry before (previous row) and class first to this preview. I do css clear: left on both of these so that everything wraps normally when the entries open.
I made your code generic, without IDs:
<div class="preview">
<p>Some preview text <a class="trigger" href="#">…</a></p>
</div>
<div class="entry">
<div class="close_button">
<a class="close" href="#">×</a>
</div>
<p>Some content text.</p>
</div>
This makes you not have to write the same code over and over.
The open/close script:
$('.trigger').click(function() {
$('.openEntry').slideUp(800); // Close the open entry
var preview = $(this).closest('.preview'); // Grab the parent of the link
// Now, clone the entry and stick it after the "last" item on this row:
preview.next('.entry').clone().addClass('openEntry').insertAfter(preview.nextAll('.last:first')).slideDown(800);
});
// Use "on()" here, because the "openEntry" is dynamically added
// (and it's good practice anyway)
$('body').on('click', '.close', function() {
// Close and remove the cloned entry
$('.openEntry').slideUp(800).remove();
});
This could be simplified a bit I'm sure, especially if you were willing to reformat your html a little more, by putting the entry inside of the preview element (but still hidden). Here is a slightly simpler version, with the html rearranged:
http://jsfiddle.net/jqmPc/2/
(I also color the first and last element on the line so you can see what is going on)
You could just get the last div in the array after calling getElementsByTagName.
var divArray = wrapperDiv.getElementsByTagName("div");
if(divArray.length > 0)
var lastDiv = divArray[divArray.length-1];
else
console.log("Empty!");
i am not able to correctly understand your question, but if you want to find out last div element in the document then you can do something like this
$("div:last")
so this will give you last div of the document
Reference:
http://api.jquery.com/last-selector/
$([1,2]).each(function(idx,el) {
$("#entry" + el).hide().insertAfter("div.entry:last");
$("#trigger" + el).click(function() {
$("#entry" + el).slideDown('800');
});
$("#close" + el).click(function() {
$("#entry" + el).slideUp('800');
});
});

I got same problem as yours, and I have been redirected to this question. But I think the answer is too complicated to my need. So I made my own way. Supposedly, you get your div list from a JSON, you can do this:
product[0] = {id: "name1", text: "text1"}
product[1] = {id: "name2", text: "text2"}
product[2] = {id: "name3", text: "text3"}
private getLastElement(id, products) {
const getTop = (id) => $("#" + id).position().top;
let itemPos = getTop(id);
let itemIndex = products.map(x => x.id).indexOf(id);
let lastID = itemIndex;
while (lastID < products.length - 1) {
if (getTop(products[lastID + 1].id) > itemPos) break;
lastID++;
}
return products[lastID].id;
}
But you can also find out by gathering all id inside your wrapper.
It works by scanning next id's row position, and return the last id of the same row.
I was looking for the same but on a single element to add style on first and last elements. #Jeff B answer helped me so alter and use it for me on one element. So the search phrase 'Get the last div in a row of floating divs' and someone looking for the same, this code may helpful:

I have three content boxes that i want to show and hide using controls.
The HTML is as follows:
<div id="leermat1">
Content here
<a class="pag-next">Next</a>
<a class="pag-prev">Previous</a>
</div>
<div id="leermat2">
Content here
<a class="pag-next">Next</a>
<a class="pag-prev">Previous</a>
</div>
<div id="leermat3">
Content here
<a class="pag-next">Next</a>
<a class="pag-prev">Previous</a>
</div>
I have the two anchors pag-next and pag-prev that will control which of the content divs should be visible at any given point:
I want to write jquery such as, when #leermat1 'pag-next' is clicked, it hides #leermat1 and shows #leermat2. Then when #leermat1 is hidden and #leermat2 shows, when '.pag-next' is clicked, it hides #leermat2, and shows #leermat3.
Also the 'pag-prev' should work the same way.
I started with the following but dont know where to go from here.
$(document).ready(function() {
$('.pag-next').on('click',function() {
$('#leermat1').addClass('hide');
$('#leermat2').addClass('show');
});
});
One more thing is that the '.pag-next' should stop functioning after it has shown #leermat3.
You need this
$('[class^=pag-]').click(function() {
var elem = $('[id^=leermat]').filter(":visible"); // take the visible element
var num = Number(elem[0].id.match(/\d+$/)[0]); // take the number from it
var step = $(this).is('.pag-next') ? 1 : -1; // ternary operator
$('#leermat'+ (num + step)).show(); // show next or back
elem.hide(); // hide the visible element
});
Looks like in your anchor tag you have not given it a class.
Next
You then go on in your JQuery code to add a click function to a class which does not exist.
$('.pag-next').on('click',function()
Try adding class="pag-next" to your anchor tag.
This is what worked for me through a little trial and error. Although I am not sure if this is the most efficient solution.
$('#leermat1 .pag-next').on('click',function(){
$('#leermat1').addClass('hide');
$('#leermat1').removeClass('show');
$('#leermat3').addClass('hide');
$('#leermat3').remove('show');
$('#leermat2').addClass('show');
});
$('#leermat2 .pag-next').on('click',function(){
$('#leermat1').removeClass('show');
$('#leermat2').addClass('hide');
$('#leermat2').removeClass('show');
$('#leermat3').addClass('show');
});
$('#leermat2 .pag-prev').on('click',function(){
$('#leermat2').addClass('hide');
$('#leermat2').removeClass('show');
$('#leermat1').addClass('show');
$('#leermat3').removeClass('show');
});
$('#leermat3 .pag-prev').on('click',function(){
$('#leermat3').addClass('hide');
$('#leermat2').addClass('show');
$('#leermat1').addClass('hide');
$('#leermat3').removeClass('show');
$('#leermat1').removeClass('show');
});
I have the following div collection in my HTML. It's designed to dynamically replicate according to user interaction.
<div class="bill-item">
<!-- Section for a single item -->
<div class="bill-item-img">
<!-- Section for Item pic -->
</div>
<div class="bill-item-description">
<!-- Section for Item description and pricing -->
<div class="bill-item-name">
<p class="bill-item-name-left">Normal Cofee</p><p class="bill-item-name-right">170.00</p>
<div class="clear"></div>
</div>
<div class="bill-item-price">
<span>170.00 USD</span>
</div>
<div class="bill-item-amount">
<span>2</span>
</div>
</div>
<div class="bill-amount-selection">
<!-- Section where the increment & decrement of item amount goes -->
<a class="amount-increase" href="#"></a>
<a class="amount-decrease" href="#"></a>
</div>
</div>
This is the HTML Rendered image of the elements.
I've written the following script to increase the bill-item-amount span value.
$(".amount-increase").click(function(){
x+=1;
$(".bill-item-amount span").html(x);
});
$(".amount-decrease").click(function(){
if(!x<=0){
x-=1;
$(".bill-item-amount span").html(x);
}
});
This works great but, it updates the value of both the span elements. what I want is to catch the event of the clicked element (which I do now) and increase the span value of the respective span. How can I filter out which span to update using javascript.?
Something like $(this).parents('.bill-item').find('.bill-item-amount span') should select the right element.
Inside your callback this is assigned to the eventSource.
You should walk the dom tree from the clicked element up until you reach the .bill-item element and the go down to the .bill-item-amount span node
$(".amount-increase").click(function(){
var $span = $(this).parent().parent().find(".bill-item-amount span");
var x = $span.html();
x+=1;
$span.html(x);
});
$(".amount-decrease").click(function(){
var $span = $(this).parent().parent().find(".bill-item-amount span");
var x = $span.html();
if(!x<=0){
x-=1;
$span.html(x);
}
});
Hi dimal update your code:
$(".amount-increase").click(function(){
x+=1;
$(".bill-item-amount").html(x);
});
$(".amount-decrease").click(function(){
if(!x<=0){
x-=1;
$(".bill-item-amount").html(x);
}
});
dont add span inside the selector [ it changes entire span values]
$(".amount-increase").click(function(){
x+=1;
$("use ur increase span id here").html(x); //
});
$(".amount-decrease").click(function(){
if(!x<=0){
x-=1;
$("use ur decrease span id here").html(x);
}
});
Inside each function the selector $(".bill-item-amount span") will find all the <span> amounts in the document. You can walk the DOM to find the correct <span> using jQuery or plain JavaScript. You seem to be using jQuery functions so my answer also uses jQuery.
The following code combines the two actions into a single function that increases or decreases the amount based on the class name of the <a> clicked. I also added a return false so that the browser will not follow the href="#" on the anchor.
$('.bill-amount-selection').on('click', 'a', function(){
var change = this.className == 'amount-increase' ? 1 : -1
var $amount = $(this).closest('.bill-item').find('.bill-item-amount span')
var amount = parseInt($amount.html(), 10) + change
$amount.html(amount < 0 ? 0 : amount)
return false
});
The use of .on() means that jQuery v1.7+ is required. I can supply a compatible function with lower jQuery versions if necessary.

I have a JS/jQuery script that adds our leads (web contacts) to the DOM in a for loop. Everything works fine except for one thing. I want the body of the lead to be hidden upon the initial display, and then have a slideToggle button to display or hide the details That means dynamically adding click events to each button as it is created. The entire HTML (HTML and a JSON object mixed into the HTML) of the lead and the slideToggle button are all appended to a node in the DOM in the for loop. Here is the pertinent part of the for loop:
// Hide the body of the lead; just show the title bar and the first line
var dataID = data[i].id
var div = $('#row' + dataID);
var more = $('#more' + dataID);
div.hide();
// Create click event for each "+" button
more.click(function() {
div.slideToggle();
});
But when I click on the "+" button to reveal the details, it opens the last div, not the div I am trying to open. This is true no matter how many leads I have on the page. How do I get the click event to open the right div. If I console.log "div" in the click event, it gives me the ID of the last div, not the one I am clicking on. But if I console.log(div) outside the click event, it has the right ID.
Also, I was unsure whether I needed the "vars" in the loop or if I should declare them outside the loop.
Here is the HTML. It's one lead plus the beginning of the next lead, which I left closed in Firebug

Try using .bind (or .on for 1.7+) and the data parameter.
more.bind("click",{target:div},function(e){
e.data.target.show();
}
or
more.on("click",{target:div},function(e){
e.data.target.show();
}
I think your basic problem is that div is common as a variable to all items. You have to separate the div's from each other by, for example, creating a local function and call it for each item. Something like:
function buildMore(div) {
more.click(function() {
div.slideToggle();
});
}
and in the loop call:
addMore(div);
p.s.
Whether you declare your variables inside or outside the loop doesn't matter: you still get the same variables.
This is because div variable gets changed and settles with the last value set in the loop.
Try this:
...
funciton createClick(div) {
return function() { div.slidToggle();
}
more.click( createClick(div) );
...
The variable div doesn't stay frozen with your click handler so it's value will be what it was at the end of the for loop and all click handlers will use the same value (which is what you're seeing).
There are a number of different ways to approach this and I thought all would be educational. Any one of them should work.
Idea #1 - Manufacture the row id from the clicked on more id
Use the id value on the clicked on link to manufacture the matching row ID. Since you create them in pairs, this can be done programmatically like this:
// Hide the body of the lead; just show the title bar and the first line
var dataID = data[i].id
$('#row' + dataID).hide();
$('#more' + dataID).click(function() {
// manufacture the row ID value from the clicked on id
var id = this.id.replace("more", "#row");
$(id).slideToggle();
});
Idea #2 - Use a function closure to "freeze" the values you want
Another way to do that is to create a function and closure that will capture the current value of div:
// Hide the body of the lead; just show the title bar and the first line
var dataID = data[i].id
var div = $('#row' + dataID).hide();
var more = $('#more' + dataID);
function addClick(moreItem, divItem) {
// Create click event for each "+" button
moreItem.click(function() {
divItem.slideToggle();
});
}
addClick(more, div);
Idea #3 - Use the HTML spatial relationship to find the row associated with a more
To make this work, you need to put a common class=lead on the top level lead div like this:
<div id="lead1115" class="lead">
And, a common class on each row:
<div id="row1115" class="row" style="display: none;">
Then, you can use the position relationships to find the row object that is in the same parent lead object as the clicked on more link like this:
// Hide the body of the lead; just show the title bar and the first line
var dataID = data[i].id
$('#row' + dataID).hide();
$('#more' + dataID).click(function() {
// find out common parent, then find the row in that common parent
$(this).closest(".lead").find(".row").slideToggle();
});
Idea #4 - Put the row ID as data on the more link
// Hide the body of the lead; just show the title bar and the first line
var dataID = data[i].id
$('#row' + dataID).hide();
$('#more' + dataID).data("row", "#row" + dataID).click(function() {
// get the corresponding row from the data on the clicked link
var rowID = $(this).data("row");
$(rowID).slideToggle();
});
I have 4 divs in a container. I want to display the html of the container which contains the divs in the textarea. I'm able to do this. The issue is, i don't want to get all the html of the container. I don't want to get #iv #three. I want to copy all the html of the container except div #three. I could use $('#three').remove() but i don't want to remove the div, I just don't want to copy it's html value to textarea. Check jsfiddle http://jsfiddle.net/rzfPP/
<div id="container">
<div id="one">test 1 </div>
<div id="two">test 2 </div>
<div id="three">test 3 </div>
<div id="four">test 4 </div>
</div>
<textarea id="save"></textarea>
var x = $('#container').html();
$('#save').val(x);
Try this
$("#container").clone().find("#three").remove().end().html();
http://jsfiddle.net/rzfPP/21/
/*
var x = $('#container').html();
$('#save').val(x);
*/
var lol = $('#container').clone()
$(lol).find('#three').remove();
$('#save').val(lol.html());
$('#container').clone().find('#three').remove().end().html();
Technically this is illegal since you are duplicating IDs, but it works fine.
http://jsfiddle.net/rzfPP/33/
Edit: Someone beat me to it :( Oh well.
var text = "";
$('#container div').each( function() {
if ( this.id != "three" ) {
text += $(this).html();
}
});
$('#save').val( text );
http://jsfiddle.net/rzfPP/31/
Basically you check the divs inside #container one by one, and check their id. If it's one you want, add their html to a string. Then at the end give that string as your textarea value.
