Loop through CSS tables and count selected cells - javascript

I am trying to loop through all the css-table and display how many cells are selected in each one.
I am using a each method but it does not seem to work.
Thanks for any help.
My code is below and this is the fiddle
jquery:
$(function () {
$('.css-table-td').click(function () {
var theTable = $(this).closest('.css-table');
$(this).toggleClass("highligh-cell");
});
});
$("#csstableinfo").click( function() {
var sCount=0;
$(".css-table div").each(function (index) {
// sCount=theTable.find('.css-table-td.highligh-cell').length; this is not workikng
alert (sCount)
});
});
Html:
<div class="css-table">
<div class="css-table-tr">
<div class="css-table-td" id="1">b</div>
<div class="css-table-td" id="2">c</div>
<div class="css-table-td" id="3">e</div>
</div>
</div>
<br/>
<div class="css-table">
<div class="css-table-tr">
<div class="css-table-td" id="1">b</div>
<div class="css-table-td" id="2">c</div>
<div class="css-table-td" id="3">e</div>
</div>
</div>
<br/>
<div class="css-table">
<div class="css-table-tr">
<div class="css-table-td" id="1">b</div>
<div class="css-table-td" id="2">c</div>
<div class="css-table-td" id="3">e</div>
</div>
</div>
<br/>
<INPUT TYPE="submit" id="csstableinfo" VALUE="Count Selected">
css:
.css-table {
display: table;
background-color:#ccc;
}
.css-table-tr {
display: table-row;
height:30px;
}
.css-table-td {
display: table-cell;
border:1px solid #fff;
width: 30px;
text-align:center;
vertical-align:middle;
}
.highligh-cell {
background: #999;
}

$(".css-table .highligh-cell").length will give you the number of selected elements, no need to use each.
$("#csstableinfo").click(function () {
alert($(".css-table .highligh-cell").length);
});
jsfiddle DEMO
EDIT:
To get how many in each table are selected:
$("#csstableinfo").click(function () {
var msg = "";
$(".css-table").each(function(index) {
var sCount = $(this).find('.highligh-cell').length;
msg += "table_" + index + " = " + sCount + "\n";
});
alert(msg);
});
Updated jsfiddle

Are you even getting an alert set? if not, the problem is with the $(".css-table div") call. You shouldn't call it this way since every div you call already containing the css table class.
try using $(".css-table"), if it's not working, it's better working with id's.
P.S. you are using different classes for each row also, so it won't identify the rows.

You just have to increase the counter and make each for the class of selected i.e .highligh-cell:
$("#csstableinfo").click( function() {
var sCount=0;
$(".highligh-cell").each(function (index) {
// sCount=theTable.find('.css-table-td.highligh-cell').length;
sCount++;
});
alert (sCount)
});

Target two fields when searching

I have this layout:
<input id="search">
<div class="entry">
<div class="title">hello</div>
<div class="description">lorem</div>
</div>
<div class="entry">
<div class="title">ipsum</div>
<div class="description">test</div>
</div>
And I allow users to search the entry divs by the content of the title div:
jQuery(document).ready(function() {
jQuery("#search").on("keyup click input", function () {
var val = jQuery(this).val();
if (val.length) {
jQuery(".entry").hide().filter(function () {
return jQuery('.title',this).text().toLowerCase().indexOf(val.toLowerCase()) != -1;
}).show();
}
else {
jQuery(".entry").show();
}
});
});
Works great. Try jsFiddle.
My question is, how do I make it so the search targets both the content of the title div and the description field?
If you want it to search for both title and description use this.
return jQuery('.title, .description',this)
Then it will look like
jQuery(".entry").hide().filter(function () {
return jQuery('.title, .description',this).text().toLowerCase().indexOf(val.toLowerCase()) != -1;
}).show();
Here is a link so you can test it.
In the filter function, you can add an OR condition that can check the description and filter results on title or description.
jQuery(document).ready(function() {
jQuery("#search").on("keyup click input", function() {
var val = jQuery(this).val();
if (val.length) {
jQuery(".entry").hide().filter(function() {
return jQuery('.title, .description', this).text().toLowerCase().indexOf(val.toLowerCase()) != -1;
}).show();
} else {
jQuery(".entry").show();
}
});
});
.entry {
background: #fff;
margin-bottom: 10px;
width: 100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="search">
<div class="entry">
<div class="title">hello</div>
<div class="description">lorem</div>
</div>
<div class="entry">
<div class="title">ipsum</div>
<div class="description">test</div>
</div>

how to check if it was the last element

how can I check if it was the last div? If it was I need to remove all classes "ready"
html:
<div class="green"></div>
<div class="orange"></div>
<div class="red"></div>
<div class="green"></div>
<div class="orange"></div>
js:
$(function() {
setInterval(showBlock, 1000);
function showBlock() {
var x = $("div:first").addClass("ready");
var c = $("div");
$(".ready").css("display", "block");
if (c.hasClass("ready")) {
$(".ready:last").next().addClass("ready");
}
}
})
;
Looking at your code what I understand is you want display one div after each second. For that I'll suggest following approach.
First add hidden class to all divs and then remove it from first hidden div at each second.
$(function() {
$('div').addClass('hidden');
var i = setInterval(showBlock, 1000);
function showBlock() {
var x = $("div.hidden:first").removeClass("hidden");
if($("div.hidden").length == 0) {
clearInterval(i);
}
}
});
.hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="green">Green</div>
<div class="orange">Orange</div>
<div class="red">Red</div>
<div class="green">Green</div>
<div class="orange">Orange</div>
As far as I understand your problem, following solution must work in your case:
$(function() {
setInterval(showBlock, 1000);
function showBlock() {
var ready_divs = $("div.ready").length;
var total_divs = $("div").length;
if(ready_divs!=total_divs){
if(ready_divs==0){
$("div:first").addClass('ready');
}else{
$("div.ready:last").next('div').addClass('ready');
}
}else{
$("div").removeClass('ready')
}
}
});
div{
width: 20px;
height: 20px;

}

Add class to an element without an id

I have a list of items:
<div class="crew-item>
<div class="crew-grid"></div>
<div class="crew-detail></div>
</div>
<div class="crew-item>
<div class="crew-grid"></div>
<div class="crew-detail></div>
</div>
<div class="crew-item>
<div class="crew-grid"></div>
<div class="crew-detail></div>
</div>
When I click on a selected 'crew-grid' I'd like to add a class ('active') to its 'crew-item' parent, but I have no idea how to achieve that using vanilla js or jQuery.
The goal is to reveal the 'crew-detail' part, with active class added to its parent.
Like this?:
$('.crew-grid').on('click', function () {
$(this).closest('.crew-item').addClass('active');
});
Basically, starting from the clicked element, get the closest ancestor element which matches that selector. You don't need an id to target an element, just a way to identify it based on the information you have (in this case the clicked element).
If you want to de-activate other elements at the same time:
$('.crew-grid').on('click', function () {
$('.crew-item').removeClass('active');
$(this).closest('.crew-item').addClass('active');
});
Using jQuery :
$('.crew-grid').click(function() {
$(this).closest('.crew-item').addClass('active');
});
Use Document.querySelectorAll()
var crews = document.querySelectorAll('.crew-item');
if (crews) {
for (var i = 0; i < crews.length; i++) {
var grid = crews[i].querySelector('.crew-grid');
grid.addEventListener('click', toggleActive, false);
}
}
function toggleActive() {
var grids = document.querySelectorAll('.crew-item');
for (var i = 0; i < grids.length; i++) {
if (grids[i].classList.contains('active')) {
grids[i].classList.remove('active');
}
}
this.parentNode.classList.add('active');
}
.crew-item.active {
background: #DDD;
}
.crew-grid:hover {
cursor: pointer;
background: #eee;
}
<div class="crew-item active">
<div class="crew-grid">crew-grid</div>
<div class="crew-detail">crew-detail</div>
</div>
<br>
<div class="crew-item">
<div class="crew-grid">crew-grid</div>
<div class="crew-detail">crew-detail</div>
</div>
<br>
<div class="crew-item">
<div class="crew-grid">crew-grid</div>
<div class="crew-detail">crew-detail</div>
</div>

swap div's position from top div's

I am trying to swap a div's position from top on and when I click another div then top div can be swap.
HTML
<div class="wrap top">
<input type="text" value="div1" class="textbox " />
</div>
<div class="wrap">
<input type="text" value="div2" class="textbox " />
</div>
<div class="wrap">
<input type="text" value="div3" class="textbox " />
</div>
jQuery
(function ($) {
$(".wrap").on("click", function () {
if ($(this).index() == 0) {
} else {
$(this).insertBefore($(this).prev());
}
});
}(jQuery));
The fact is I don't want to remove the div which I click instead want to swap the positions around.
How Can I do this using jQuery itself?
I would suggest using css to position the top div and just swap the class as follows:
(function ($) {
$(".wrap").on("click", function () {
if ($(this).index() == 0) {
} else {
$(".wrap").removeClass("top");
$(this).addClass("top");
}
});
}(jQuery));
this will swap whatever you click with the first element.
$(".wrap").on("click", function () {
var $this = $(this);
if ($this.index() == 0) {
} else {
var first = $this.siblings('.wrap').first();
first.insertBefore($this);
$this.prependTo($this.parent());
}
});
if you just want to move the clicked element to the top, you can simply do
$this.prependTo($this.parent());
To swap the two DOM elements using jQuery, you could use something like this: -
(function($) {
$(".wrap").on("click", function(event) {
var index = $(event.target).index();
var first = $(".wrap").first();
if (index > 0) {
$(first).swapWith(this);
}
});
}(jQuery));
jQuery.fn.swapWith = function(to) {
return this.each(function() {
var copy_to = $(to).clone(true);
var copy_from = $(this).clone(true);
$(to).replaceWith(copy_from);
$(this).replaceWith(copy_to);
});
};
.wrap {
height: 100px;
width: 200px;
margin: 10px 10px 10px 10px;
background-color: #2d8cd0;
}
h2 {
color: white;
text-align: center;
padding-top: 20px;
pointer-events: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="wrap">
<h2>1</h2>
</div>
<div class="wrap">
<h2>2</h2>
</div>
<div class="wrap">
<h2>3</h2>
</div>
<div class="wrap">
<h2>4</h2>
</div>

jquery keypress to add class

I am trying to learn jquery keypress to add class system.
I have tryed the following code but it doesn't worked. I have tryed with an ID here. When started the #ttt1 then the the #rb1 background color should change but nothing happened.
What i am doing wrong or what i need to do here? Anyone can tell me ?
This id DEMO from codemep.io
$(document).ready(function() {
var ID = $(this).attr("id");
$("#ttt" + ID).on('keypress', function() {
if ($(this).val().length > 20) {
$("#rb" + ID).addClass("ad");
} else {
$("#rb" + ID).removeClass("ad");
}
});
});
HTML
<div class="container">
<div class="tWrp">
<textarea class="test" id="ttt1" placeholder="Write"></textarea>
</div>
<div class="br" id="rb1">Button</div>
</div>
<div class="container">
<div class="tWrp">
<textarea class="test" id="ttt2" placeholder="Write"></textarea>
</div>
<div class="br" id="rb2">Button</div>
</div>
You are defining a variable ID inside a function which occurs on $(document).ready(). Inside that function the value this will point to the document. What you need to do is to define the variable inside the keypress event handler function.
Use class for selection and then use $(this).attr("id") inside the handler function. Also you can use $(this).closest('div').next() to get the next element in the parent.
DEMO
$(document).ready(function() {
//here value for this is the document object and the id is not useful.
$(".test").on('keyup', function() {
//but here value for this is textarea where keypress event happened.
var ID = this.id;
if (this.value.length > 20) {
$(this).closest('div').next().addClass("ad");
} else {
$(this).closest('div').next().removeClass("ad");
}
});
});
.container {
margin:0px auto;
width:100%;
max-width:500px;
position:relative;
margin-top:100px;
}
.test {
outline:none;
border:1px solid red;
width:100%;
min-height:100px;
}
.br {
background-color:blue;
width:100px;
height:40px;
}
.ad {
background-color:red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<div class="container">
<div class="tWrp">
<textarea class="test" id="ttt1" placeholder="Write"></textarea></div>
<div class="br" id="rb1">Button</div>
</div>
<div class="container">
<div class="tWrp">
<textarea class="test" id="ttt2" placeholder="Write"></textarea></div>
<div class="br" id="rb2">Button</div>
</div>
