Making a div hidden and visible according to the chosen option under select tag

My code don't seem to work.
So i have a div like this:
<div class="abc">
<form>
**some input tags**
then this:
<select>
<option value="" onclick="myfx1()">yes</option>
<option value="" onclick="myfx2()">no</option></select>
And this is my js code:
<script type="text/javascript">
function myfx1(){
document.getElementById("hid").style.visibility="hidden";
}
function myfx2(){
document.getElementById("hid").style.visibility="visible";
}
</script>
***************and below is the div that has to appear when no is selected**********************
<div id="hid">
<select>
**some options**
</select>
<font>
**some text**
</font>
**some more textarea and input tags**
</div>
**end of the div**
then it ends with a button:
<input type="button" style="float:right" value="Go">
</div></form>

<select onchange='myfx1(this.value)'>
<option value="1" >yes</option>
<option value="0" >no</option></select>
<script type="text/javascript">
function myfx1(value){
if(value==1) {
document.getElementById("hid").style.visibility="hidden";
}else {
document.getElementById("hid").style.visibility="visible";
}
}</script>

HTML
<select name='options' id="select">
<option value='yes'>Yes</option>
<option value='no'>No</option>
</select>
<div id="hid">
Test
</div>
JS
var elem = document.getElementById("hid");
document.getElementById('select').addEventListener('change', function(){
if(this.value == 'yes'){
elem.style.visibility="visible";
}else{
elem.style.visibility="hidden";
}
})

$("#YourSelectBoxID").change(function(){
if($(this).val() == "YourDesiredConditionForCheckWhichValueIsSelected") {
$(".abc").hide();
} else {
$(".abc").show();
}
});

Change the CSS attribute if an option selected with jQuery

I have this code:
<select>
<option disabled selected>Select Method</option>
<option value="question">Question</option>
<option value="password">Password</option>
<option value="email">Email</option>
<option value="none">None</option>
</select>
Now I want when user select each of them some div that hidden in css with display:none; get visible for example when user select Question the div that have question id get visible or when Password selected the div that have password id get visible.
I try this but not work:
$(document).ready(function(){
if ($("#auth option:selected").text() == "question"){
$("#question").css("display","block");
}
});
So how can I do this?

If you follow the pattern you have done so far, you have to write code for each option. If your options and div elements are coupled with value and id, you can simply do like this,
$("select").change(function() {
$("div").hide();
$("#" + $(this).val()).show();
});
Demo Fiddle

Here is Demo for this , remove disabled from select tag so that user can select the options
Jsfiddle
http://jsfiddle.net/adarshkr/z9gcf40r/2/
Code
HTML
<select id="showdiv">
<option disabled selected>Select Method</option>
<option value="question">Question</option>
<option value="password">Password</option>
<option value="email">Email</option>
<option value="none">None</option>
</select>
<div id="question" class="hide">
<p>question</p>
</div>
<div id="password" class="hide">
<p>password</p>
</div>
<div id="email" class="hide">
<p>email</p>
</div>
<div id="none" class="hide">
<p>none</p>
</div>
CSS
.hide{
display:none
}
JAVASCRIPT
$("select").change(function(){
$("div").hide();
$("#"+$(this).val()).show();
});

try this,
$('#auth').on('change', function() {
var that = $(this).val();
if (that === "question"){
$("#question").css("display","block");
}
});

Better check value than the text.
$(document).ready(function(){
if ($("#auth option:selected").val() == "question"){
$("#question").css("display","block");
}
});

Jquery dynamic hide and show for drop down menu

I am having trouble making my drop down menu dynamically show blocks of html code which are labelled style="display:none".
I have following code.
<script type="text/javascript">
$(\'select[name="questiontype"]\').change(function(){
if ($(this).val() == "multiple")
alert("call the do something function on option multiple");
else
alert("call the do something function on option programming");
});​
</script>
<form action="addQuestion.php" method="post">
<select name="questiontype">
<option name="questiontype" value="multiple" click="return showMultiple();">Multiple Choice< /option>
<option selected name="questiontype" value="programming" click="return showProgramming();">Programming< /option>
</select><br>
<input type="hidden" name="course" value="'.$course.'" />
<div id=\'multiple\' style="display:none">
Multiple
</div>
<div id=\'programming\' style="display:none">
Programming
</div>
</form>
i tried these functions to .show() the div's by id from the dropdown menu but no luck and I'm not sure what I'm doing wrong. I also removed some code in the div id blocks to make it easier to read.
<script>
function showMultiple(){
$('#multiple').show();
$('#programming').hide();
return false;
}
function showProgramming(){
$('#multiple').hide();
$('#programming').show();
return false;
}
</script>

demo
HTML
<select id="selectMe">
<option value="multiple">multiple</option>
<option value="programming">Programming</option>
</select>
<br><br><br>
<div id="multiple" class="group" >
Multiple
</div>
<div id="programming" class="group" >
Programming
</div>
JS
$(document).ready(function () {
$('.group').hide();
$('#multiple').show();
$('#selectMe').change(function () {
$('.group').hide();
$('#'+$(this).val()).show();
})
});

In your select option you are using click instead of onclick event
<select name="questiontype">
<option name="questiontype" value="multiple" onclick="return showMultiple();">Multiple Choice</option>
<option selected name="questiontype" value="programming" onclick="return showProgramming();">Programming< /option>
</select>
And no need to use escape for single quotes,
<div id='multiple' style="display:none">
Multiple
</div>
<div id='programming' style="display:none">
Programming
</div>
and in script tag
$('select[name="questiontype"]').change(function(){

Try this:
<form action="addQuestion.php" method="post">
<select name="questiontype" id="questiontype">
<option value="multiple">Multiple Choice</option>
<option selected value="programming">Programming</option>
</select>
<br>
<div id='multiple' class="group" style="display:none">
Multiple
</div>
<div id='programming' style="display:none" class="group">
Programming
</div>
</form>
Put this code in head section:
<script src="jquery-1.9.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$('.group').hide();
$('#programming').show();
$('#questiontype').change(function () {
$('.group').hide(1000);
$('#'+$(this).val()).show(1000);
})
});
</script>

Show divs based on dropdown - Script not working

I'm trying to show div's based on dropdown selection using the following script.
It works perfectly on a simple page without any thing in it; but when I put it in the page that I'm developing, it messes up the entire page, making it black and at the end of the URL I get this ...../myPage.html#someIdInThePage .
JS:
<script type="text/javascript">
$(document).ready(function () {
function showTheTab(name) {
name = '#' + name;
$('div').not(name).hide();
$(name).show();
}
$('#dropdown').change(function () {
showTheTab($(this).val());
});
showTheTab($('#dropdown').val());
});
</script>
HTML:
<form>
<p>
<select id="dropdown" name="dropdown">
<option value="Pubs" 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>
<div id="Pubs">pubs</div>
<div id="Councils">councils</div>
<div id="Property">property</div>
<div id="Various">various</div>
<div id="Universitys">universitys</div>

This line: $('div').not(name).hide(); will hide every div on your page apart from the selected div. You're going to need a more specific selector to do the hiding
Example
Javascript:
$(document).ready(function () {
function showTheTab( name )
{
name = '#' + name;
$('div.Tabs > div').not(name).hide();
$(name).show();
}
$('#dropdown').change( function() {
showTheTab( $( this ).val() );
});
showTheTab( $('#dropdown').val() );
});
Html:
<form>
<p>
<select id="dropdown" name="dropdown">
<option value="Pubs" 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>
<div class="Tabs">
<div id="Pubs">pubs</div>
<div id="Councils">councils</div>
<div id="Property">property</div>
<div id="Various">various</div>
<div id="Universitys">universitys</div>
</div>

Jquery/Js: Hide/Show Divs based on select box option values

These are Dynamic dependent select controls. The sets of values of (1-3, 4-6, 7-9) determine the use hide/show divs function. The problem is the function i have only hide/show depending on the div id. How can i make the function hide/show div depended on the values(1-3, 4-6, 7-9) found in the selectbox?
Jquery
$('#select').change(function() {
$('#sub1, #sub2, #sub3').hide();
$('#sub' + $(this).find('option:selected').attr('id')).show();
});
Html Setup
<html>
<select size="6" id="category">
<option value="">categories 1-3 </option>
<option value="">----</option>
<option value="">----</option>
</select>
<div id="sub1" style="display:none">
<select name="subc1" size="6">
<option value="1">subcategories 4-6</option>
<option value="2">---</option>
<option value="3">---</option>
</select>
</div>
<div id="sub2" style="display:none">
<select name="subc2" size="6">
<option value="4">subcategories 7-9</option>
<option value="5">----</option>
<option value="6">----</option>
</select>
</div>
<div id="sub3" style="display:none">
<select name="subc3" size="6">
<option value="7">End</option>
<option value="8">----</option>
<option value="9">----</option>
</select>
</div>
</html>

select the value from drop down change function and do the operation depends on the value of drop down, following is the sample code
$(function() // Shorthand for $(document).ready(function() {
$('select').change(function() {
if($(this).val() == 1)
{
$('#sub1').hide();
$('#sub2').show();
}
});
});

You nee to change minor change in your category select
<select size="6" id="category">
<option value="1">categories 1-3 </option>
<option value="2">----</option>
<option value="3">----</option>
</select>
$('select#category').on('change', function() {
$('div[id=^sub]:visible').hide();
$('div#sub' + this.value).show();
});
can also use .change() instead of .on('change').
$('select#category').change(function() {
$('div[id=^sub]:visible').hide();
$('div#sub' + this.value).show();
});
NOTE:
$('div[id=^sub]:visible') will point to all divs that have id start with sub and visible.
You are trying with $('#select') which need to be $('#category') or $('select#category').
According to your comment:
Complete solution will look like following:
function isOnlyDashed(text) {
return text.replace(/-/g, '').length === 0;
}
$('select#category').change(function() {
var text = $('option:selected', this).text();
if (!isOnlyDashed(text)) {
$('div[id=^sub]:visible').hide();
$('div#sub' + this.value).show();
}
});
$('select[name^=subc]').change(function() {
var text = $('option:selected', this).text();
if (!isOnlyDashed(text)) {
$(this).parent() // jump to parent div
.next('div[id^=sub]:hidden') // go to next hidden div
.show();
}
});
Complete Workout

The problem with your code is that you have an incorrect selector.
$('#select')...
should be
$('select')...
Also, this part is wrong
$('#sub' + $(this).find('option:selected').attr('id')).show();
Replace it with this
$('#sub' + $(this).val()).show();
Finally, having different elements with the same name/id "sub1" is probably a bad idea, though technically not illegal. It is certainly confusing.

working demo http://jsfiddle.net/FwBb2/1/
I have made minor changes in your Jquery code as well as added value in your first select drop-down list which was missing rest hope this helps.
Please lemme know if I missed anything! B-)
