dynamic drop down menu for labels - javascript

I currently have a drop down menu displaying 3 options. Once the user selects an option, another drop down menu will display itself based on the choice from the first menu.
The first dropdown(InDiameter):
<label for="innerdiameter"><i class="fa fa-asterisk text-danger"></i>1. Inner Diameter:(*)
<select id="InDiameter" name="InDiameter">
<option value="N/A">Select</option>
<option value="Standard(1.0-5.0mm)">Standard(1.0-5.0mm)</option>
<option value="Microcuff(0.3-0.75mm)">Microcuff(0.3-0.75mm)</option>
<option value="Nanocuffs(56-250μm)">Nanocuffs(56-250μm)</option>
</select>
</label>
Second dropdown(Standard):
<label for="standard"> <br>1a. Inner Diameter for Standard:
<select id="Standard" name="Standard">
<option value="N/A">Select</option>
<option value="1mm">1mm</option>
<option value="1.5mm">1.5mm</option>
<option value="2mm">2mm</option>
<option value="2.5mm">2.5mm</option>
<option value="3mm">3mm</option>
<option value="3.5mm">3.5mm</option>
<option value="4mm">4mm</option>
<option value="5mm">5mm</option>
</select>
</label>
I've tried several js solutions, but none of them have worked. Any help would be appreciated.

in this case you need some one code of javascript and jquery:
the html code:
<label >Select:</label>
<select id="InDiameter" name="InDiameter" required onchange="miFuncion($(this).val());">
<option value="N/A">Select</option>
<option value="Standard">Standard(1.0-5.0mm)</option>
<option value="Microcuff">Microcuff(0.3-0.75mm)</option>
<option value="Nanocuffs">Nanocuffs(56-250μm)</option>
</select>
<div id="selectStandar" style="display:none;">
<label>Standard:</label>
<select id="Standard" name="Standard">
<option>Select</option>
<option value="1mm">1mm</option>
<option value="1.5mm">1.5mm</option>
<option value="2mm">2mm</option>
<option value="2.5mm">2.5mm</option>
<option value="3mm">3mm</option>
<option value="3.5mm">3.5mm</option>
<option value="4mm">4mm</option>
<option value="5mm">5mm</option>
</select>
</div>
<div id="selectMicrocuff" style="display:none;">
<label>Microcuff:</label>
<select id="Microcuff" name="Microcuff">
<option value="1">Microcuff 1</option>
<option value="2">Microcuff 2</option>
</select>
</div>
code jquery and Javascript
function miFuncion(value_selected){
if (value_selected=='Standard'){
$("#selectStandar").show();
$("#selectMicrocuff").hide();
}
if (value_selected=='Microcuff'){
$("#selectMicrocuff").show();
$("#selectStandar").hide();
}
}//end function
in this case i validate the first select(InDiameter), take the value and if is a Standard i show the div that have the select with the options Standard..and etc..
is only a method exist differentes methods..

Auto select two options based on drop-down list

I have the following HTML code to select Salesman, State, and Office Number. What I want to be able to do is select the Salesman and have it auto select the State and Office Number for that person:
<label for="saleman">Senior Agent: </label>
<select id="salesman" name="salesman">
<option value="" selected="selected"></option>
<option value="Tammy Sizemore">Tammy Sizemore</option>
<option value="Ron Jeffries">Ron Jeffries</option>
<option value="Tony Clark">Tony Clark</option>
<option value="Mark Sengala">Mark Sengala</option>
<option value="Judy Donato">Judy Donato</option>
<option value="Mary Porter">Mary Porter</option>
</select>
<label for="state">State: </label>
<select id="state" name="state">
<option value="" selected="selected"></option>
<option value="Iowa">Iowa</option>
<option value="Kansas">Kansas</option>
<option value="Maine">Maine</option>
<option value="Ohio">Ohio</option>
<option value="Pennsylvania">Pennsylvania</option>
<option value="West Virginia">West Virginia</option>
</select>
<label for="number">Office Number: </label>
<select id="number" name="number">
<option value="" selected="selected"></option>
<option value="A219">A219</option>
<option value="A256">A256</option>
<option value="G019">G019</option>
<option value="G222">G222</option>
<option value="Q161">Q161</option>
<option value="Q341">Q341</option>
</select>
The problem I'm having is that it's a fairly complex decision process as to who belongs where. For example:
If I select 'Tammy Sizemore', I know she's in Kansas in office A256.
If I select 'Ron Jeffries', I know he's in Maine at office Q161.
I'm somewhat familiar with implementing jQuery or JavaScript. The page is being rendered by PHP. If it can be done in one of those, I'm fine. I just don't know how to implement this.
Is there an efficient way to do this?
Here's the work-around I came up with (in case someone else finds this handy):
When setting up the drop-down list, I combined the three elements (Name, State, and Office Number) into a single value but only showed the Salesman name.
<label for="saleman">Senior Agent: </label>
<select id="salesman" name="salesman">
<option value="" selected="selected"></option>
<option value="Tammy Sizemore,Kansas,A256">Tammy Sizemore</option>
<option value="Ron Jeffries,Maine,Q161">Ron Jeffries</option>
<option value="Tony Clark,West Virginia,G019">Tony Clark</option>
<option value="Mark Sengala,Ohio,Q341">Mark Sengala</option>
<option value="Judy Donato,Iowa,A219">Judy Donato</option>
<option value="Mary Porter,Pennsylvania,G222">Mary Porter</option>
</select>
Then, when I needed to split them back into separate fields, I used explode.
$sr_agent = $_POST['salesman'];
$sa = explode(',', $sr_agent);
$agent_name = $sa[0];
$agent_state = $sa[1];
$agent_office = $sa[2];
I'd recommend not using the value attribute as you did in your work-around solution, as you're basically using the value attribute for something other than its intended use. You can use custom data attributes that are perfect for this...
// cache the state & office elements so we don't have to search the DOM every time
var $state = $("#state");
var $office = $("#office");
$("#salesman").on("change", function() {
// find the selected option
var $selected = $(this).find("option:selected");
// get the associated state and office...
var state = $selected.data("state");
var office = $selected.data("office");
// set the dropdowns
$state.val(state);
$office.val(office);
});

how to link category <option> tags

I want to link categories to their own pages. so I mean when I click to 'Hotels' it should open the page which is Category/Hotels
this is the current code
<select name="category">
<option value="">Any Category</option>
<option value="clubs">Clubs</option></a>
<option value="hotels">Hotels</option>
<option value="pubbar">Pub&Bar</option>
<option value="restaurants">Restaurants</option>
</select>
lets say I want to link like that
<option value="www.website.com/event_cat/clubs/> Clubs </option>
<option value="www.website.com/event_cat/hotels/> Hotels </option>
.. and so on
but when I do, its directing to this page:
www.website.com/events/?time=&category=%2Fevent_cat%2Fclubs%2F&location=
JSfiddle Demo
<html>
<body>
<form name="blah_blah">
<select name="ddmenu_name" id="ddmenu_name" style="width: 80% !important;">
<option value="" selected>Select Site</option>
<option value="http://www.yahoo.com">Yahoo!!!</option>
<option value="http://www.gmail.com">Gmail</option>
<option value="http://www.google.co.in">Google</option>
<option value="http://www.facebook.com">Facebook</option>
</select>
<input type="button" name="Submit" value="Go!" onClick="window.open(ddmenu_name.value,'newtab'+ddmenu_name.value)">
</form>
</body>
</html>
You just have to use full domain path with http or https(if its a secure server)
<option value="http://www.website.com/event_cat/clubs/> Clubs </option>
<option value="http://www.website.com/event_cat/hotels/> Hotels </option>
Since you have the first option already selected, in the first option, keep the value empty and add the onchange, as per the code below:
<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
<option value="">Any Category</option>
<option value="www.website.com/event_cat/clubs/">Clubs</option>
<option value="www.website.com/event_cat/hotels/">Hotels</option>
<option value="pubbar">Pub&Bar</option>
<option value="restaurants">Restaurants</option>
</select>

javascript get value of <select>

I know that i can do something like that
document.getElementById("whatever").value
But i have code like that
<select id="year_architecture_third_choose" style="display: none">
<option value="" style="display:none;"></option>
<option value="207">Lectures</option>
<option value="208">Courses</option>
<option value="209">Sheets</option>
<option value="210">Others</option>
</select>
<select id="year_architecture_fourth_choose" style="display: none">
<option value="" style="display:none;"></option>
<option value="211">Lectures</option>
<option value="212">Courses</option>
<option value="213">Sheets</option>
<option value="214">Others</option>
</select>
</select>
<select id="year_architecture_second_choose" style="display: none">
<option value="" style="display:none;"></option>
<option value="203">Lectures</option>
<option value="204">Courses</option>
<option value="205">Sheets</option>
<option value="206">Others</option>
</select>
This is just a small part of the code . I don't want to make getElementById() for each one i need better idea
You could use the document.geteElementsByTagName('select') method which will return a collection of all <select> elements in your DOM that you could then loop through and do whatever you originally intended to do on the element.
Reference: document.getElementsByTagName.

Changing window URL with drop down?

<form name="roomForm">
<select name="roomMenu"
onChange="window.location = this.roomForm.roomMenu.options[this.roomForm.roomMenu.selectedIndex].value">
<option value="">Choose ICU</option>
<option value="All">All</option>
<option value="/base/ICU5/example">ICU5</option>
<option value="/base/ICU6/example">ICU6</option>
<option value="/base/ICU7/example">ICU7</option>
</select>
</form>
Could someone point out why this piece of code is not working? It should redirect to another page when the drop down menu is changed.
Your code has extra ")" and this itself is select box. jsfiddle
<form name="roomForm">
<select name="roomMenu"
onChange="window.location = this.options[this.selectedIndex].value;">
<option value="">Choose ICU</option>
<option value="All">All</option>
<option value="/base/ICU5/example">ICU5</option>
<option value="/base/ICU6/example">ICU6</option>
<option value="/base/ICU7/example">ICU7</option>
</select>
</form>​

i want add in drop down menu an option with value: "custom" that when i select this option appear just below a field blank as input text where i can add my personalized text so i can insert personalized category
it's possible?
maybe you mean something like this: http://jsbin.com/ubihuw/edit#javascript,html
so in php or something you can check then the "my_own_text" field ... dont know what you will exactly do ;)
js:
$('.input').change(function()
{
if($(this).attr('value') == "0") {
$('#choose_own_text').append('<input type="text" id="my_own_text" name="my_own_text" value="Please type in .." />');
} else {
$('#choose_own_text').empty();
}
});
your code ...
<p><div id='contactform_category_errorloc' class='err'></div>
<select name="category" class="input">
<option value="0" selected="selected">
[choose yours]
</option>
<option value="Arts and entertainment">Arts and entertainment</option>
<option value="Automotive">Automotive</option>
<option value="Business">Business</option>
<option value="Computers">Computers</option>
<option value="Games">Games</option>
<option value="Health">Health</option>
<option value="Internet">Internet</option>
<option value="News and Media">News and Media</option>
<option value="Recreation">Recreation</option>
<option value="Reference">Reference</option>
<option value="Shopping">Shopping</option>
<option value="Sports">Sports</option>
<option value="World">World</option>
</select>
<div id="choose_own_text"></div>
</p>
