I have 5 divs that are exactly the same, inside each div i have a select option input .. all divs have the same id so i want to get the nearest div of select and then do innerHTML inside.
So i want something like:
$(this).closest('div[maybeidhere?]').innerhtml ='whole content here';
Thanks in advance
EDIT : Ignore the same id, lets say all have same class
<div>
<select id="faculty" onchange="inchange(this)">
<option value="fos">Faculty of Science</option>
<option value="fot">Faculty of Information Technology</option>
<option value="foe">Faculty of Engineering</option>
<option value="other">Other</option>
</select>
<div class="degreediv"></div>
</div>
<script>
function inchange(input){
if($(input).val()=="fot"){
$(this).closest('div[.degreediv]').innerhtml ='FOT CONTENT';
}
else if($(input).val()=="fos"){
$(this).closest('div[.degreediv]').innerhtml ='FOS CONTENT';
}
else if($(input).val()=="foe"){
$(this).closest('div[.degreediv]').innerhtml ='FOE CONTENT';
}
else if($(input).val()=="other"){
$(this).closest('div[.degreediv]').innerhtml ='other CONTENT';
}
};
</script>
Since select is inside the divs you can rather use .Parent() function
$(this).parent().innerhtml;
<select>
<option value="value1">1</option>
<option value="value2">2</option>
<option value="value3">3</option>
</select>
<div>this is div 1</div>
<div>this is div 2</div>
...
<div>this is div n</div>
If your code resembles this then:
$textOfDiv = $('select + div').val(); // selects text inside first DIV element
or
$htmlOfDiv = $('select + div').html(); // selects html inside first DIV element
Note that jQuery selector works similar to CSS selector.

i need to show/hide different div based on the selected option of a dropdown menu. I've tried all the solutions explained in the previous tickets. When they use jQuery libraries, the show/hide action works, but they get in conflict with other page elements (ex. image sliders and counter bar are hidden). All the others solutions don't work, despite the one explained in this ticket (How can I show a hidden div when a select option is selected?). It works well, but only with two values. I need to extend this method to more than two values.
i write here the working code.
function showDiv(divId, element)
{
document.getElementById(divId).style.display = element.value == 1 ? 'block' : 'none';
}
#hidden_div {
display: none;
}
<select id="test" name="form_select" onchange="showDiv('hidden_div', this)">
<option value="0">No</option>
<option value="1">Yes</option>
</select>
<div id="hidden_div">This is a hidden div</div>
P.S.: I'm not an expert in javascript. Thanks again.
I have modified the solution you referred to and it seems to be working (if I understand your question correctly):
HTML:
<select id="test" name="form_select" onchange="showDiv(this)">
<option value="hidden_div1">Show div 1</option>
<option value="hidden_div2">Show div 2</option>
<option value="hidden_div3">Show div 3</option>
<option value="hidden_div4">Show div 4</option>
</select>
<div id="hidden_div1">This is hidden div 1</div>
<div id="hidden_div2">This is hidden div 2</div>
<div id="hidden_div3">This is hidden div 3</div>
<div id="hidden_div4">This is hidden div 4</div>
CSS:
div[id*="hidden_div"] {
display: none;
}
javascript:
// When the page loads, make sure the already selected div is shown.
window.onload = function afterPageIsLoaded() {
showDiv();
}
function showDiv(element) {
// Create an array of all the hidden divs elements.
const hiddenDivs = [...document.querySelectorAll("div[id*='hidden_div']")];
// Loop over them and hide every one of them.
hiddenDivs.map(hiddenDiv => hiddenDiv.style.display = 'none');
// Get the selected id from the select.
const id = document.getElementById('test').value;
// Get the selected div and display it.
document.getElementById(id).style.display = 'block';
}

If I misinterpreted your question or something is not clear, let me know!
I want the content displayed to be manipulated by selecting a dropdown option. Here's what I have so far. It doesn't work.
HTML - here's an example of my dropdown.
<select id="dropdown">
<option value="Week1" id="Week1drop">Week 1 - Greetings, Common Adjectives & Planets</option>
</select>
The div below will be hidden by default using {display: none} in CSS.
<div id="week1">
<h1>Greetings, Common Adjectives & Planets</h1>
</div>
JavaScript - Below I've got an event listener to check for a change to the dropdown, which whill call the UpdateDom Function.
The function should be identifying that the user has selected Week1 on the dropdown and using Jquery .show() to make the Div visible.
document.getElementById("dropdown").addEventListener("change", updateDom);
function updateDOM () {
if (document.getElementById('dropdown').value == "Week1") {
$("#week1").show();
}
}
I hope this makes sense, does anyone know where I'm going wrong?
Apart from the typo you found yourself, if you have jQuery, USE it.
Also options do not have IDs
$("#dropdown").on("change", function() {
$("#week1").toggle(this.value == "Week1"); // same as $(this).val()
}).change(); // initialise on load
#week1 {
display: none
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="dropdown">
<option value="">Please select</option>
<option value="Week1">Week 1 - Greetings, Common Adjectives & Planets</option>
</select>
<div id="week1">
<h1>Greetings, Common Adjectives & Planets</h1>
</div>
I am building a filtering tool using a select element. When you choose something from the drop down, it should filter the divs below to show only the div for that item.
I am targeting the divs using the select value which is also the class of the div the item is in. So for example, if you choose shirts in the drop down the value would be item-shirts and a div below would have a class of item-shirts.
I have figured out how to hide everything that doesn't have the class of the selected item when something is selected. But I can't figure out how to unhide everything when something else is selected. Any help would be greatly appreciated!
Here is my HTML
<select>
<option value="item-shirts">Shirts</option>
<option value="item-shoes">Shoes</option>
<option value="item-shoes">Pants</option>
</select>
<div class="item-section item-shirt></div>
<div class="item-section item-shoes></div>
<div class="item-section item-pants></div>
Here is my jQuery
$('select').on("change", function() {
var value = $('select').val();
if($('.item-section').hasClass(value)) {
$('.item-section.'+value).siblings().hide();
} else {
$('.item-section.'+value).siblings().show();
}
This is similar to adding an active class to a list/group of elements. Typically what you do is loop through all the elements removing the active class (even though it's only applied to one element), then add the active class to the specific element. In your case you might want to hide all DIVs, then show the specific DIV.
var $sections = $( '.item-section' );
$('select').on( 'change', function ( e ) {
$sections.hide();
$( '.' + this.value ).show();
} );
.item-section {
margin: 2rem 0;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
<option value="item-shirts">Shirts</option>
<option value="item-shoes">Shoes</option>
<option value="item-pants">Pants</option>
</select>
<div class="item-section item-shirts">Shirt</div>
<div class="item-section item-shoes">Shoes</div>
<div class="item-section item-pants">Pants</div>
Note: You had a few errors in your markup that I changed to make everything work. i.e. Duplicate values for your <option> tags and some missing quotes.
I've done a couple performance improvements too.
You also don't need $( 'select' ).val() inside of your event handler. The context of the handler is the <select> element so you can use the this.value instead and skip jQuery querying the DOM to do the same.
I've also cached the .item-section elements so you're not querying the DOM over and over again on each change of the select.
There was no need to test for hasClass(). All you need to do is get the value from the selected option and show the <div> having that class. I added an extra empty option so that when you select it, it will show all <div>s.
$('select').on("change", function() {
var value = $('select').val();
if (value) {
$(".item-section").hide();
$("." + value).show();
} else {
$(".item-section").show();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
<option value=""></option>
<option value="item-shirt">Shirts</option>
<option value="item-shoes">Shoes</option>
<option value="item-shoes">Pants</option>
</select>
<div class="item-section item-shirt">Shirts</div>
<div class="item-section item-shoes">Shoes</div>
<div class="item-section item-pants">Pants</div>
I have a selection menu (drop down list).
<select>
<option id="one" value="something">Car</option>
<option id="two" value="anything">Plane</option>
</select>
& the following div which located in somewhere in my page.
<div id="somediv">This is a string.</div>
I want to display the above div upon selecting the second item of the menu (id="two").
I have 2 questions: (1) What is the best way to keep this div hidden by default? I will just add display:none; to its styling, but maybe there is a better solution? (2) How can I make the div show up when the option of id="two" is selected? Any answer would be greatly appreciated.
So I wrote a simple jquery script that does what you described. Let me know if it fixes your problem. You can also do this with javascript, but I think jquery works for this just fine.
http://codepen.io/Francisco104/pen/vEPRgp
$('select').change(function(){
decide($(this));
});
var decide = function (elem) {
var touch = elem;
if (touch.val() === 'anything') {
return $('#somediv').css('display', 'block');
}
};
For hiding it by default, using style="display: none"is the easiest. You could do it using jquery $('div#somediv').hide(); but I don't see any benefit to that other than you possibly wanting to keep the show/hide logic together.
Here are two simple solutions using a change() event.
If div#somediv should be shown permanently when option#two has been selected:
$("select").change(function() {
if ($(this).val() == 'anything') $('div#somediv').show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
<option id="one" value="something">Car</option>
<option id="two" value="anything">Plane</option>
</select>
<div id="somediv" style="display: none">This is a string.</div>
If div#somediv should be shown while option#two is selected and disappear if the user selects another option:
$("select").change(function() {
$('div#somediv').toggle($(this).val() == 'anything');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
<option id="one" value="something">Car</option>
<option id="two" value="anything">Plane</option>
</select>
<div id="somediv" style="display: none">This is a string.</div>
You should probably give an id to the select as well, to make the jQuery selector less brittle.
So, I'd have a class for the div, let's say, is-hidden and my CSS will have .is-hidden { display: none; }. Then, do the following.
HTML:
<div id="somediv" class="is-hidden">This is a string.</div>
JS:
$div = $("#somediv");
$("select").on("change", function() {
$div.is(".is-hidden") || $div.addClass("is-hidden");
//Option 1
if ($(this).find(":selected")[0].id === "two") {
$div.removeClass("is-hidden");
}
//Option 2 (same as above, but a bit shorter)
$(this).find(":selected")[0].id === "two" && $div.removeClass("is-hidden");
});
Here is what you can do:
in your html file:
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
</head>
<select>
<option id="one" value="something">Car</option>
<option id="two" value="anything">Plane</option>
</select>
You'll need to import the JQuery library (which I show you there right above the <select> element) so that you can execute your script.
In your css file:
#somediv {
display: none;
}
and finally here is the script that will show the dive when "plane" is selected
$('select').change(function(){
$('#somediv').css('display','block');
});
Take a look at this JSFIDDLE I made for you.
1) You can hide the div initially giving the css property display:none; or by setting its display property using javascript which will run in initial load.
2) You can listen to the onchange event of the selectfield and check if value is 'anything' then show the div by changing its display style property to block and hidden in other cases.
document.getElementById("somediv").style.display='none';
var showHideDiv=function(selectField){
var divElement=document.getElementById("somediv");
if (selectField.value=='anything')
divElement.style.display='block';
else
divElement.style.display='none';
}
<select onchange='showHideDiv(this)'>
<option id="one" value="something">Car</option>
<option id="two" value="anything">Plane</option>
</select>
<div id="somediv">This is a string.</div>
The simplest way to hide within HTML
<div hidden>content</div>
To display an hidden div
$(document).ready(function(){
$("select").change(function () {
$( "select option:selected").each(function(){
if($(this).attr("value")=="anything"){
$("#somediv").show();
}
});.
});
Display none works.
Have you tried keying into the onchange event? http://www.w3schools.com/jsref/event_onchange.asp?
Hi I have some javascript which works in a standalone web page with 5 divs, what it does is when an option is selected it will show a div and hide the others based on drop down selection.Basically what the code does is when a sector is selected on the drop down that corresponding DIV will be displayed eg pubs.
The problem I am having is in the web page I want this working on I have lots of Div tags and when the page loads all the Divs on the page are hidden, obviously I don't want this.
Any help would be much appreciated
The code that hides all the divs on page load is
$('div').not(name).hide();
Is there a way of solving this problem I cant see how I am going to get round it at the moment.?
JS
<script>
$(document).ready(function () {
function showTab( name )
{
name = '#' + name;
$('div').not(name).hide();
$(name).show();
}
$('#dropdown').change( function() {
showTab( $( this ).val() );
});
showTab( $('#dropdown').val() );
});
HTML
<form>
<p>
<select id="dropdown" name="dropdown">
<option value="Pub-Chains" selected="selected">Pubs </option>
<option value="Councils">Councils </option>
<option value="Property">Property </option>
<option value="Various">Various </option>
<option value="Universitys">Universitys </option>
</select>
</p>
</form>
My Div's are named like so
Div id="Pub-Chains"
Div id="Councils"
Div id="Property"
Div id="Various"
Div id="Universitys"
You have to group up the div you want to participate in show hide to separate them from other divs on the page. You can assign a common class to them and use that class to hide them.
Div id="Pub-Chains" class="opt"
Div id="Councils" class="opt"
Div id="Property" class="opt"
Div id="Various" class="opt"
Div id="Universitys" class="opt"
$('div.opt').hide();
$(document).ready(function () {
var ddl = $("#dropdown");
$('#' + ddl.val()).show().siblings().hide();
ddl.change(function () {
$('#' + $(this).val()).fadeIn().siblings().hide();
});
});
See demo
If your target <div>s are all siblings then you can easily do something like follows.
<div>
<div id="Pub-Chains">
<div id="Councils">
<div id="Property">
...
</div>
$(function(){
$("select#dropdown").change(function(){
$('#' + $(this).val()).show().siblings().hide();
}).change();
});
See it here.
If you have a more complicated layout then you can think of using classnames to group the <div> elements.
try this:
$(document).ready(function () {
function showTab( name ){
name = '#' + name;
$(name).siblings().hide(); //<-- hide this way
$(name).show();
}
and if this is not working then you can do this just put it outside of doc ready handler
function showTab( name ){
name = '#' + name;
$(name).siblings().hide(); //<-- hide this way
$(name).show();
}
$(document).ready(function () {
// then all your change stuff here
create a parent div to all this div... and call it in selector..
try this
<div id="tabdivs">
Div id="Pub-Chains"
Div id="Councils"
Div id="Property"
Div id="Various"
Div id="Universitys"
</div>
jquery
*updated*
$('#tabdivs').children().not(name).hide();
