Within a div wrapper with a class of "section", I have dozens of HTML elements repeated across the page that look like this:
<div class="section">
<div class="article"></div>
<div class="article"></div>
<div class="article"></div>
</div>
And each contains certain information inside. Now, what I'm trying to do is once the page loads, show only the first 5, hide the rest in a new div inserted with jQuery, and when this new div is clicked it will display the next five , and then the next five on click again, and so on until the end. The idea is that this new div will function as a button that will always be positioned at the end of the page and will respond to these orders I just mentioned. So far I've got this down:
$('.section').each(function () {
var $this = $(this),
$allArticles = $this.find('.article');
if ($allArticles.length > 5) {
$('<div/>').addClass('hidden-articles').appendTo(this).append($allArticles.slice(5));
$('.hidden-articles .article').hide();
}
});
And that hides all but the first five. But now for the rest of the process, I can't get it to work. I don't seem to be able to select properly those hidden div with class "article" and manipulate them to function the way I described above. I would appreciate it a lot if someone more experienced with jQuery could guide me in the right direction and maybe offer a snippet. Many thanks in advance!
You can use the :hidden and :lt selectors to get the functionality you are looking for..
$('.section').each(function() {
var $this = $(this),
$allArticles = $this.find('.article');
if ($allArticles.length > 5) {
$('<div/>').addClass('hidden-articles')
.appendTo(this).append($allArticles.slice(5));
$this.find('.hidden-articles .article').hide();
}
});
$('#show').on('click',function() {
var $hidden = $('.hidden-articles .article:hidden:lt(5)');
$hidden.show();
});
UPDATE
// If one one element to search
var elem = '.section' ;
hideArticles(elem);
// If Multiple Elements on the page...
$('.section').each(function() {
hideArticles(this);
});
$('#show').on('click', function() {
var $hidden = $('.hidden-articles .article:hidden:lt(5)');
$hidden.show();
});
function hideArticles(elem) {
var $this = $(elem),
$allArticles = $this.find('.article');
if ($allArticles.length > 5) {
$('<div/>').addClass('hidden-articles')
.appendTo(this).append($allArticles.slice(5));
$this.find('.hidden-articles .article').hide();
}
}

I have a page where I have a table with a class. This table sometimes occurs multiple times on the page. I need to do the same jquery function on each instance. How do I achieve that with jquery...???
Here is my jquery:
jQuery(window).load(function () {
if(jQuery('.ezfc-summary-table tr:eq(2) td:eq(1)').text()=='1 layer'){
jQuery('.ezfc-summary-table tr:eq(5)').hide();
jQuery('.ezfc-summary-table tr:eq(6)').hide();
jQuery('.ezfc-summary-table tr:eq(8)').hide();
}
});
#devlin carnate - i'm trying to do another thing, which is to take the text from one of the td's and append it to another class (product-title), which also appears multiple times. Here is what i have tried, but it only takes the text from the first td it finds, and appends it to all the following classes.
$(document).ready(function() {
$('.ezfc-summary-table').each(function(i, obj) {
var table = $(this);
if (table.find('tr').eq(2).find('td').eq(1).text() == '1 layer') {
table.find('tr').eq(5).hide();
table.find('tr').eq(6).hide();
table.find('tr').eq(8).hide();
var getpartname = $('.ezfc-summary-table tr:eq(0) td:eq(1)').text();
$('.product-title').append('<span style="padding-left: 5px;">'+getpartname+'</span>');
}
});
});
Could you help me solve this problem also...???
Thanks in advance
You can iterate over the class assigned to the tables using jQuery $.each() and hide the rows based on whether the '1 layer' text condition is met:
$(document).ready(function() {
$('.ezfc-summary-table').each(function(i, obj) {
var table = $(this);
if (table.find('tr').eq(2).find('td').eq(1).text() == '1 layer') {
table.find('tr').eq(5).hide();
table.find('tr').eq(6).hide();
table.find('tr').eq(8).hide();
}
});
});
Here is a Fiddle Demo : https://jsfiddle.net/zephyr_hex/f45umhkp/2/
The title is a bit of a tongue twister. A brief description of the fiddle, is that it's a toggle style accordion where the toggle state changes color when one of the divs is toggled. I've got it working to where if another div is toggled it will close that previous div and open the new div while changing the toggle state.
The issue I am running into is if a user wants to close the current toggle without clicking a different div it will close the current toggle but not change the toggle state back to it's original state. I am currently using this and have tried multiple things including if the container 'is: visible' or hasClass then to remove the toggle class, but nothing seems to work. I've also tried a different slideToggle function, but of course that applied it to the toggled element I've found.
Fiddle: http://jsfiddle.net/NFTFw/1256/
What I am trying to do?
I want the current toggle class to change back to its original state if the user clicks the current toggled div or clicks another div. So essentially I want the user to have either option.
CODE:
$(document).ready(function () {
$('.column').each(function (index) {
$(this).delay(750 * index).fadeIn(1500);
});
$('.column').hide();
$('.body').hide();
$('.column').each(function () {
var $toggle = $(this);
$('.toggle', $toggle).click(function () {
$(".toggle").removeClass("toggle-d");
$(this).addClass('toggle-d');
$body = $('.body', $toggle);
$body.slideToggle();
$('.body').not($body).hide();
});
});
});
Check to see if the thing that you're clicking already has the class. If so, remove it, if not, add it. I suspect the problem you were having with hasClass() is that you were attempting to check the wrong this.
Oooh I did a bad thing and didn't remove the class when a new div was clicked. I've fixed that and updated the jsfiddle
jsfiddle
js:
$(document).ready(function () {
$('.column').each(function (index) {
$(this).delay(750 * index).fadeIn(1500);
});
$('.column').hide();
var width = $(window).width();
if (width <= 600) {
$('.body').hide();
$('.column').each(function () {
var $toggle = $(this);
$('.toggle', $toggle).click(function () {
if($(this).hasClass('toggle-d')){
$(this).removeClass("toggle-d");
}
else{
$('.toggle').removeClass('toggle-d');
$(this).addClass('toggle-d');
}
$body = $('.body', $toggle);
$body.slideToggle();
$('.body').not($body).hide();
});
});
}
});
What i would suggest is to pass the element itself in the function
in the index.html Do this
<a class = 'classname' onclick = toggle(this)>
Your Content Here
</a>
After that in the script.js
what i am saying is in javascript, i believe you can easily convert it to jquery
function toggle(value){
if(value.className == 'the predefined value'){
value.className = value.className + ' Your new class addition'
// remember there should be a space if you are adding an additional class to the present class, else directly change the classname
}
else{
value.className = 'the predefined value'
}}
this will toggle your classname whenever the element is clicked
Hello I am new to programming so please excuse my ignorance.
I have several elements that when clicked use the ScrollTop jQuery function to scroll to a specified point (in another bootstrap nav-tab). I have about 20 different elements that when clicked do this. I have resorted to writing 20 different functions that look similar to the one below. I'm sure there must be a way to store these pairs and have a single ScrollTop function that calls upon those pairs.
$('#element').click(function(e) {
e.preventDefault();
var target = $('#element2').closest('.tab-pane').attr('id');
showTab(target);
setTimeout(function() {
$('html, body, nav').animate({
scrollTop: $("#element2").offset().top -100
}, 500);
}, 500);
});
So my js file has twenty or so of this function, where "#element" and "#element2" are subbed with "#alpha" "#alpha2", "#beta" "#beta2", etc...
Should I be using an array? a class? Thanks for you time.
See Working Fiddle Here
Yes you can add same class to all element that you want fire click on them, to reduce code see HTML example :
<span class="scrollTop" id="element">element text</span>
<span class="scrollTop" id="alpha">alpha text</span>
<span class="scrollTop" id="beta">beta text</span>
Adding two lignes to javascript code:
JS :
var id = $(this).attr('id'); //Id of clicked item
var scrollToId = '#'+id+"2"; //Id of scrolled to item
After that replace static ids by dynamic ones (scrollToId, id).
FULL JS :
$('.scrollTop').click(function(e) {
e.preventDefault();
var id = $(this).attr('id'); //Id of clicked item
var scrollToId = '#'+id+"2"; //Id of scrolled to item
var target = $(scrollToId).closest('.tab-pane').attr('id');
showTab(target);
setTimeout(function() {
$('html, body, nav').animate({
scrollTop: $(scrollToId).offset().top -100
}, 500);
});
});
Try adding the class "element" to each of the items that have an element id followed by a number - no need to remove the id at this time.
Then, change the selector in your code to be:
$('.element').click(function(e) {
If you use the class name instead of the id, you'll get notified when any item with a class of "element" is clicked.
If you need to make special allowances based on which one it is - in your single function, you could then check which one you're dealing with by checking its id:
$(this).attr('id')
Good Luck!
I may be going in the completely wrong direction with what I'm trying to do, so I wanted to ask for help.
Background / Overview
I need to display a paragraph of text and allow a user to select one or more words from the paragraph and save their highlighted text to a database, for just their profile. Actually, hat selection of text will eventually be (1) stored with the highlight AND (2) linked up to another set of highlighted text from another paragraph (basically, I'm tying a phrase from one source to a reference source)
What I've tried...
I have tried to put each word of the paragraph into a DIV (and a unique ID) with each DIV set to float left, so that the display looks okay.
<style>
div { float: left}
</style>
and...using an example:
<div id="GEN_1_1">
<div id="GEN_1_1_1">In</div>
<div id="GEN_1_1_2">the</div>
<div id="GEN_1_1_3">beginning</div>
<div id="GEN_1_1_4">God</div>
<div id="GEN_1_1_5">created</div>
<div id="GEN_1_1_6">the</div>
<div id="GEN_1_1_7">heaven</div>
<div id="GEN_1_1_8">and</div>
<div id="GEN_1_1_9">the</div>
<div id="GEN_1_1_10">earth</div>.
</div>
Which looks like: In the beginning God created the heaven and the earth. (minus the bold)
So far, I have used the
window.getSelection()
function to determine/grab the words that have been highlighted.
I then tried using this:
if (window.getSelection)
{
selected_len = window.getSelection().toString().length;
if (window.getSelection().toString().length>0)
{
div_id = window.getSelection().getRangeAt(0).commonAncestorContainer.parentNode.id;
}
}
to get the ID's for each DIV selected, BUT I only get a single DIV ID returned right now.
Help Request:
Is there are slick way to get the ID for each DIV selected and put it into an Array, so that I can construct a SQL query to put it into the database (the query is easy)? The selected words could total up to several hundred, if not a thousand words, so I need to make sure the solution will work with a ton of words selected.
UPDATE: JSFIDDLE DEMO
I modified the code again. See if it works for you now.
$(document).ready(function () {
$(document).on('mouseup keyup', '.checked', function () {
console.log(window.getSelection());
if (window.getSelection().toString().length>0) {
var count = window.getSelection();
var arr = [];
$('.checked span').each(function(){
var span = $(this)[0];
var isT = window.getSelection().containsNode(span, true);
if(isT){
arr.push($(this).attr('id'));
}
});
console.log(arr,count.toString());
alert(arr);
alert(count.toString());
}
});
});
I created a fiddle for solution. Check it out here: http://jsfiddle.net/lotusgodkk/GCu2D/18/
Also, I used span instead of div for the text selection. I hope that won't be an issue for you. So the code works as you want. It will return the id of the parent span in which text is selected. You can modify it to save the ID into array or as per your needs.
$(document).ready(function () {
$(document).on('mouseup', '.checked', function () {
if (window.getSelection) {
var i = getSelectionParentElement();
console.log(i);
alert('parent selected: ' + i.id);
}
});
});
function getSelectionParentElement() {
var parent = null, selection;
if (window.getSelection) {
selection = window.getSelection();
if (selection.rangeCount) {
parent = selection.getRangeAt(0).commonAncestorContainer;
if (parent.nodeType != 1) {
parent = parent.parentNode;
}
}
} else if ((selection = document.selection) && selection.type != "Control") {
parent = selection.createRange().parentElement();
}
return parent;
}
I am trying to sort my site out so that when I click an anchor link it highlights the heading and the paras underneath it. I have it nearly right but am struggling with a few issues.
I have some HTML like:
<p id="pp1" class="Subsubhead">Stuff</p>
<p>Nonsense</p>
<p>More</p>
<p id="pp7" class="Subsubhead">Meow</p>
<p>Lorem</p>
<p class="subhead">
and I have some javascript that nearly works like:
function highlight(elemId) {
var elem = $(elemId);
elem.nextUntil(".Subsubhead").addClass("snaphighlight");
//elem.addClass("snaphighlight");
setTimeout(function () {
elem.removeClass("snaphighlight")
}, 1000);
}
$('#navigation a').click(function (event) {
var elemId = '#' + $(this).attr('href').split('#')[1];
highlight(elemId);
});
This currently doesn't highlight the heading, but it does highlight the <p> tags underneath it until the next Subsubhead. however, when the next p has a class of Subhead, it keeps highlighting which I don't want either. Is there a way of telling it to nextUntil ".subsubhead"&&".subhead" or something similar? also my timeout doesn't work anymore. how can i fix that?
You are applying the class to numerous elements but only removing it from one
Try this:
function highlight(elemId) {
var elem = $(elemId);
var highlight=elem.nextUntil(".Subsubhead").addClass("snaphighlight");
//elem.addClass("snaphighlight");
setTimeout(function () {
highlight.removeClass("snaphighlight")
}, 1000);
}
Your syntax using ## for a jQuery selector is invalid, should only use one #
