Change the CSS attribute if an option selected with jQuery - javascript

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();
});

Here is Demo for this , remove disabled from select tag so that user can select the options
Jsfiddle

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");
}
});

How to show input and remove it based on select box?

I have two input I need to show one of them based on the select box:
html code:
<select id="type-price">
<option value="">Choose one...</option>
<option value="numeric">Numeric </option>
<option value="percentage">Percentage</option>
</select>
<div id="input_type1">
<input type="text" name="Numeric">
</div>
<div id="input_type2">
<input type="text" name="Percentage">
</div>
jQuery code:
$('#type-price').on('change',function(){
if($(this).val()=== "numeric"){
$("#input_type1").show();
$("#input_type2").hide();
}else if ($(this).val()=== "percentage"){
$("#input_type1").hide();
$("#input_type2").show();
}
});
Now it's totally fine like that but my issue I have php request when I show input_type1 then hide input_type2 the request pick up second one which is null so I need to delete the hide one at all form Dom tree!

You can empty the div which contain the input and you will have only one input in your DOM. On each change of select, it will fill the concerne div by the input html.
Also you'd used wrong selector, the # selector is for id and you have used an class in your HTML code.
The JQuery class selector is ..
function removeAll() {
$("#input_type1").html('');
$("#input_type2").html('');
}
removeAll();
$('#type-price').on('change',function(){
removeAll();
if ($(this).val() === "numeric"){
$("#input_type1").append('<input type="text" value="numeric">');
} else if ($(this).val() === "percentage"){
$("#input_type2").append('<input type="text" value="percentage">');
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="type-price">
<option value="" disabled selected>Choose one...</option>
<option value="numeric">Numeric </option>
<option value="percentage">Percentage</option>
</select>
<div id="input_type1">
<input type="text" value="numeric">
</div>
<div id="input_type2">
<input type="text" value="percentage">
</div>

Here is an example with one field.
$(function() {
$("#type-price").change(function(e) {
$(".input-type").fadeIn("slow").find("input").attr("name", $(this).val().toLowerCase());
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="type-price">
<option value="">Choose one...</option>
<option value="numeric">Numeric </option>
<option value="percentage">Percentage</option>
</select>
<div class="input-type" style="display: none;">
<input type="text">
</div>

Besides some syntax problem in your jQuery class selector, Thinking about performance, It's simply better to prevent the (non-visible) input from being sent.
Shorter coding and less dom manipulation.
$('#type-price').on('change',function(){
$('.input_type1').toggle($(this).val()=="numeric");
$('.input_type2').toggle($(this).val()=="percentage");
});
//To prevent the non-visible from being posted
//Eithr we check the form using submit handler or the button and prevent the
//from being sent do our stuff then send it...
$('#myForm').submit(function() {
$('input:hidden').attr('name', '');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="myForm">
<select id="type-price">
<option value="">Choose one...</option>
<option value="numeric">Numeric </option>
<option value="percentage">Percentage</option>
</select>
<div class="input_type1">
<input name="inp1" type="text" placeholder="1">
</div>
<div class="input_type2">
<input name="inp2" type="text" placeholder="2">
</div>
<input type="submit" value="Send">
</form>

Get div html with select value of dynamically created select in jquery

I dynamically created a div with select options in jQuery. Here's a sample.
<div id="myDiv">
<select id="mySelect">
<option selected value="0">A</option>
<option value="1">B</option>
<option value="2">C</option>
<option value="3">D</option>
</select>
</div>
0 is the default selected value.
When I get html of the div like this $("#myDiv").html(), it gets the below.
<div id="myDiv">
<select id="mySelect">
<option selected value="0">A</option>
<option value="1">B</option>
<option value="2">C</option>
<option value="3">D</option>
</select>
</div>
It's the same as the above code which is normal.
However, when I change the selected value to 2, $("#myDiv").html() is still getting same code. 0 is still the selected value.
How can I get the html of the div, with the dynamically changed value?

You can do this :
$('#yourSelect option:selected').val()

Maybe like this:
function create_select(){
var select=$('<select/>').attr('id','mySelect');
var option0=$('<option/>').val(0).text('A').attr('selected', true);
select.append(option0);
var option1=$('<option/>').val(1).text('B');
select.append(option1);
var option2=$('<option/>').val(2).text('C');
select.append(option2);
var option3=$('<option/>').val(3).text('D');
select.append(option3);
$('#myDiv').empty().append(select);
}
function change_select_value(_new_val){
$('#mySelect option').removeAttr('selected');
$('#mySelect').val(_new_val).change();
}
$(document).on('change', '#mySelect', function(){ //conctruction for Dynamically created element
alert('change value to =>'+this.value); //or $(this).val();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<div id="myDiv"></div>
<input type="button" value="Create Select" onclick="create_select();" /></br>
<input type="button" value="Set option C (value=2)" onclick="change_select_value(2);" /></br>

$('#myDiv').find("#mySelect").change(function () {
alert($("#mySelect option:selected").text());
alert($("#mySelect option:selected").val());
});

jquery click not work on select tag in chrome

I have a problem with jquery click in my code. my code this is:
<script>
$(document).ready(function(){
$("#hide").click(function(){
$(".mapg").hide();
});
$("#show").click(function(){
$(".mapg").show();
});
});
</script>
<select name="showmapg" id="showmapg" class="form-control" required>
<option value="0">Select</option>
<option id="show" value="1">Yes</option>
<option id="hide" value="2">No</option>
</select>
<p class="mapg" style="display: none;">Hello</p>
my code work in firefox but it's not work in chrome. how can do it?

You should register your click event to select element itself and not to its options..
Making it as simple as possible. Try this
$(document).ready(function(){
$("#showmapg").change(function(){ // or .click(function(){
if(this.value == 2) {
$(".mapg").hide();
}else{ //use else if , if you want to nothing to happen on select option
$(".mapg").show();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="showmapg" id="showmapg" class="form-control" required>
<option value="0">Select</option>
<option id="show" value="1">Yes</option>
<option id="hide" value="2">No</option>
</select>
<p class="mapg" style="display: none;">Hello</p>

your code would be:
<script>
$(document).ready(function(){
$("#showmapg").change(function(){
if($(this).val()==1){
$('.mapg').show();
}
else if($(this).val()==2){
$('.mapg').hide();
}
});
});
</script>

Click event is not valid for option elements. Use .change() event of select to show/hide element:
$('#showmapg').change(function(){
if($(this).val()=="1")
$(".mapg").show();
else
$(".mapg").hide();
});

How do I select a specific option value from a drop down list to show a hidden div?

I have a drop down list that has 4 options, so what I want is when I click on the value "from" it shows a hidden div (used CSS to hide this div "display: none;"). anyone can help me with that? THANKS!
Html:
<select id="type">
<option value="">--select--</option>
<option value="category">Category</option>
<option value="brand_name">Brand</option>
<option value="campaign_name">Campaign</option>
<option value="from">Recap date</option>
</select>
</label>
<div id="showfrom">
<input type="text" class="filter" value="02-16-2012" id="from">
</div>
Js:
$("#type").change(function() {
var selected = $(this).find(':selected').val();
if (selected == from) {
$("#showfrom").show();
}
});

from should be a string literal. Also you need to hide if something else is selected so better if you can use .toggle()
$("#type").change(function () {
$("#showfrom").toggle(this.value == 'from');
}).change();//to set the initial state

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.
