When click on click here it's still alert 0.
How can i count length div by id using javascript ?
function swipeDislike() {
var $photo = $("div.content").find('#photo');
alert($photo.length);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<div onclick="swipeDislike()">
click here
</div>
<div id="content">
<div id="photo">
DIV content photo
</div>
</div>
Your selector is id not class.
Change var $photo = $("div.content").find('#photo');
To
var $photo = $("div#content").find('#photo');
Working Code Snippet:
function swipeDislike() {
var $photo = $("div#content").find('#photo');
alert($photo.length);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<div onclick="swipeDislike()">
click here
</div>
<div id="content">
<div id="photo">
DIV content photo
</div>
</div>
You have a typo instead of div.content use div#content
$("div#content").find('#photo') instead of $("div.content").find('#photo')
But the best way would be to just use $(“div#content #photo”); this way you won't need to use two expensive jQuery calls. Thanks Jaromanda X :)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<div onclick="swipeDislike()">
click here
</div>
<div id="content">
<div id="photo">
DIV content photo
</div>
</div>
<script>
function swipeDislike() {
var $photo = $("div#content #photo");
alert($photo.length);
}
</script>

Here is the html:
<div
className="myClass"
>
<div
className="resizerClass"
id="tomatoes"
>
<div className="resizers">
</div>
</div>
<div className="resizers"></div>
</div>
I need the id os resizerClass div? how to get it?
If you want to find ID by jQuery as your HTML attributes(className) then you can define attribute in square bracket like $('[className="resizerClass"]') and get other attributes value like attr('id').
$(document).ready(function(){
var getId = $('[className="resizerClass"]').attr('id');
console.log('id='+getId);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div className="myClass">
<div className="resizerClass" id="tomatoes">
<div className="resizers"></div>
</div>
<div className="resizers"></div>
</div>
I want to show all the nodes of my html page inside a div.
What i have so far (js):
var nodes = document.getElementsByTagName("*");
div3.innerHTML = nodes;
And html:
<body>
<div id="content">
<div id="1-1">
<div id="div1"></div><br>
<div id="div2"></div><br>
<div id="div3"></div><br>
<div id="div4"></div><br>
<div id="div5"></div>
</div>
</div>
<script src="script201.js" rel="text/javascript"></script>
</body>
The output I get from this code in div3: [object HTMLCollection]
How do I get all the nodes to show like:
BODY
DIV
DIV
DIV
DIV
DIV
DIV
DIV
SCRIPT
So every node in the file basically
You have to loop through all the nodes so that you get the nodeName property individually.
Please Note: Since document object has some other tags like HTML, HEAD, STLYLE, SCRIPT etc., all of them will be targeted with * selector.
var nodes = [...document.getElementsByTagName("*")];
nodes.forEach(function(el){
div3.innerHTML += el.nodeName + ' ';
})
<body>
<div id="content">
<div id="1-1">
<div id="div1"></div><br>
<div id="div2"></div><br>
<div id="div3"></div><br>
<div id="div4"></div><br>
<div id="div5"></div>
</div>
</div>
<script src="script201.js" rel="text/javascript"></script>
</body>
You can use JavaScript querySelectorAll method, which is used to select all the nodes based on the parameter we passed. for example if we pass * inside document.querySelectorAll('*'), it selects all the node in the document. "*" is the universal selector.
var allNode=document.querySelectorAll('*')
console.log(allNode)
<body>
<div id="content">
<div>
<div id="div1"></div><br>
<div id="div2"></div><br>
<div id="div3"></div><br>
<div id="div4"></div><br>
<div id="div5"></div>
</div>
</div>
<script src="script201.js" rel="text/javascript"></script>
</body>
Use element_name.querySelectorAll('*') to get all elements inside it.
var b=document.getElementById('div3')
document.querySelectorAll('*').forEach(e=>b.innerHTML+=e.nodeName + "<br>")
<body>
<div id="content">
<div id="1-1">
<div id="div1"></div><br>
<div id="div2"></div><br>
<div id="div3"></div><br>
<div id="div4"></div><br>
<div id="div5"></div>
</div>
</div>
<script src="script201.js" rel="text/javascript"></script>

Hello I have this html code:
<div class="row newrow">
<div class="col-10"><b>this</b></div>
<div class="col-2">
<img src="close.png" id="exit"/>
</div>
</div>
When I click on img with id exit using this code
$('body').on('click','#exit',function(e){
})
I need to get the text of the <b>behind it which would be "this"
I have tried this but it does not work:
$('body').on('click','#exit',function(e){
$q = $(e.target).prev('b')
var word = $q.text()
)}
It only gives me the that I clicked from the beginning
try this:
$('body').on('click','#exit',function(e){
var this_b = $(this).parent().prev().children(0).html();// get the text
alert(this_b);
});
You can use $(this).closest('.row').find('b'):
$('#exit').click(function(e){
$q = $(this).closest('.row').find('b');
var word = $q.text();
console.log(word);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row newrow">
<div class="col-10"><b>this</b></div>
<div class="col-2">
<img src="close.png" id="exit"/>
</div>
</div>
You need to select the parent of the clicked img to get the the .col-2, and then get the col-2's prev() to get to the .col-10, and then you can access its children() to get the children (the single <b>). Also, there's no need for e.target if you use this:
$('body').on('click', '#exit', function() {
$q = $(this).parent().prev().children();
var word = $q.text()
console.log(word);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row newrow">
<div class="col-10"><b>this</b></div>
<div class="col-2">
<img src="close.png" id="exit" />
</div>
</div>
Try this
$('body').on('click','#exit',function(e){
var word = $(this).closest('.newrow').find('b').text();
});
I'm stuck with a menu I'd love to add to my website.
I have branched my work in:
Commercial
Fashion
Music
Portrait
So I have a menu like this one above.
When I click on one section, let's say "Commercial" I want all the others to be display:none.
Have a look at this FIDDLE: http://jsfiddle.net/bfevLsj2/8/
$(document).ready(function() {
$("#commercial").click(function() {
$(".commercial").toggleClass("show");
$(".fashion").toggleClass("hid");
$(".music").toggleClass("hid");
$(".portrait").toggleClass("hid");
});
});
You need siblings() width jquery
Description: Get the siblings of each element in the set of matched elements, optionally filtered by a selector.
$("[id]").click(function(){ //onclick on element with ID
var selected = $(this).attr("id"); // save the value of that ID
$("."+ selected).show().siblings("[class]").hide()//find the class with the same value as class and show it then find all siblings class and hide them
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="commercial">Commercial</div>
<div id="fashion">Fashion</div>
<div id="music">Music</div>
<div id="portrait">Portrait</div><br />
<div class="commercial">C</div>
<div class="fashion">F</div>
<div class="music">M</div>
<div class="portrait">P</div>
BUT a better approach would be to use data-*
$("[data-tab]").click(function(){
var current = $(this).attr("data-tab");
$("[data-content="+ current +"]").show().siblings("[data-content]").hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div data-tab="commercial">Commercial</div>
<div data-tab="fashion">Fashion</div>
<div data-tab="music">Music</div>
<div data-tab="portrait">Portrait</div><br />
<div data-content="commercial">C</div>
<div data-content="fashion">F</div>
<div data-content="music">M</div>
<div data-content="portrait">P</div>
AGAIN it is better to use pure javascript
function runClick (event) {
var current = this.getAttribute("data-tab");
for( var content = 0; content < dataContent.length; content++) {
dataContent[content].style.display = "none"
}
document.querySelector("[data-content="+ current + "]").style.display = "block"
}
var dataTabs = document.querySelectorAll("div[data-tab]"),
dataContent = document.querySelectorAll("div[data-content]");
for(var tab = 0; tab < dataTabs.length; tab++){
dataTabs[tab].addEventListener("click", runClick , false);
}
<div data-tab="commercial">Commercial</div>
<div data-tab="fashion">Fashion</div>
<div data-tab="music">Music</div>
<div data-tab="portrait">Portrait</div><br />
<div data-content="commercial">C</div>
<div data-content="fashion">F</div>
<div data-content="music">M</div>
<div data-content="portrait">P</div>
HTML:
<div id="commercial" class="menuItem">Commercial</div>
<div id="fashion" class="menuItem">Fashion</div>
<div id="music" class="menuItem">Music</div>
<div id="portrait" class="menuItem">Portrait</div><br />
<div class="commercial content">C</div>
<div class="fashion content">F</div>
<div class="music content">M</div>
<div class="portrait content">P</div>
JavaScript:
$(document).ready(function(){
$(".menuItem").click(function(){
var id = this.id;
$('.content').removeClass('show').addClass('hid');
$('.'+id).addClass('show').removeClass('hid');
});
});
CSS:
.hid {
display:none;
}
.show {
display:block;
}
Fiddle
Have a look at this fiddle, think it's what you want
Essentially you can use .toggle() to traverse and show/hide according to whether it's the one you want to show.
$(function(){
// find all the links that you can click
$("div.clickable a").click(function(e) {
// when they're clicked, find the identifier of
// the tab/div you want shown
var clickedId = $(e.target).parent("div").attr("id");
// traverse all of the divs and show/hide according
// to whether it's the tab you want
$("div.section").each(function(index, div) {
$(div).toggle($(div).hasClass(clickedId));
});
});
});
And the HTML:
<div id="commercial" class="clickable">Commercial</div>
<div id="fashion" class="clickable">Fashion</div>
<div id="music" class="clickable">Music</div>
<div id="portrait" class="clickable">Portrait</div>
<br />
<div class="commercial section">C</div>
<div class="fashion section">F</div>
<div class="music section">M</div>
<div class="portrait section">P</div>
HTH
Edited to add an "ALL" link in this fiddle
$("div.clickable a").click(function(e) {
// when they're clicked, find the identifier of
// the tab/div you want shown
var clickedId = $(e.target).parent("div").attr("id");
// traverse all of the divs and show/hide according
// to whether it's the tab you want
$("div.section").each(function(index, div) {
$(div).toggle($(div).hasClass(clickedId) || clickedId=="ALL");
});
});
After adding this to the list of clickable divs:
<div id="ALL" class="clickable">
ALL
</div>
Your could that more easy like:
<div class="link" id="commercial">Commercial</div>
<div class="link" id="fashion">Fashion</div>
<div class="link" id="music">Music</div>
<div class="link" id="portrait">Portrait</div><br />
<div class="commercial elem">C</div>
<div class="fashion elem">F</div>
<div class="music elem">M</div>
<div class="portrait elem">P</div>
<script type="text/javascript">
$(document).ready(function(){
$(".link").click(function(){
var id = $(this).attr('id');
$('.elem').hide();
$('.' + id).show();
});
});
</script>
Please see the following code:
<div id="song" class="s1">
<div class = "l">foo</div>
<div class="r">
<div>foo</div><div>foo</div>
<div class="link">Link</div>
</div></div>
<div id="song" class="s2">
<div class = "l">foo</div>
<div class="r">
<div>foo</div><div>foo</div>
<div class="link">Link</div>
</div></div>
<div id="song" class="s3">
<div class = "l">foo</div>
<div class="r">
<div>foo</div><div>foo</div>
<div class="link">Link</div>
</div></div>
There are several more s like these. I've to get the link from the first <div> whose ID is song only using JavaScript because I've fetched this data using php into an <object> tag.
Thank you :)
You should use JQuery like (at the bottom of your file):
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script>
var links = $.map($('div#song .link a'), function(a) { return $(a).attr('href'); });
console.log(links);
</script>
Output:
["some url", "some url", "some url"]
Noting only the first set,
<div id="song1" class="s1">
<div class = "l">foo</div>
<div class="r">
<div>foo</div>
<div>foo</div>
<div class="link">Link</div>
</div>
You can get the link which is some url by
var link = $(".s1").find("a");
console.log(link.attr('href') );
