I have multiple select box in Html, I need to validate the options select then open a new page taking me to a page where the teacher's profile and the school selected, I need to create a page for each possible answer.
Select Teacher to Study with and School
<select id="school">
<option value="Once" selected="">One</option>
<option value="Twice">Two</option>
<option value="Three">Three</option>
<option value="Four">Four</option>
</select>
<select id="teacher">
<option value="Once" selected="">Sam</option>
<option value="Twice">Micheal</option>
<option value="Three">Manny</option>
<option value="Four">Jenny</option>
</select>
Use this with jQuery
$(function() {
$('#school, #teacher').change(function() {
//You can validate here if you want
var myWindow = window.open("http://yourserver.com/myapp/" + $("#school").val() + "/" + $("#teacher").val(), "MsgWindow", "width=800, height=600");
});
});
Add a onchnge event
HTML:
<select id="school">
<option value="Once" selected="" onchange="toggle();">One</option>
<option value="Twice">Two</option>
<option value="Three">Three</option>
<option value="Four">Four</option>
</select>
<select id="teacher">
<option value="Once" selected="" onchange="toggle();">Sam</option>
<option value="Twice">Micheal</option>
<option value="Three">Manny</option>
<option value="Four">Jenny</option>
</select>
JS:
function toggle(){
// to do : your logic goes here
// redirect to new page
}
you can use better approach
var url = "http://yourserver.com/myapp/";
$(function() {
$('#school, #teacher').on("change",function() {
window.open( url + $("#school").val() + "/" + $("#teacher").val());
});
});

I have this Fiddle : https://jsfiddle.net/Ardee12/tL643rjq/3/
My problem is, I always get the same options at the third select from second select (vice versa), after I select an option from the first one. I need to stick for their own option (second and third select), but still have the populated function from their "rel" attribute. Can anyone please help me?
$(document).ready(function () {
$(".mainSelect").change(function() {
if ($(this).data('options') === undefined) {
$(this).data('options', $('.kidSelect option').clone());
}
var rel = this.options[this.selectedIndex].getAttribute('rel');
var options = $(this).data('options').filter('[rel=' + rel + ']');
$('.kidSelect').html(options);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<select class="mainSelect">
<option rel="1">Fruit</option>
<option rel="2">Animal</option>
<option rel="3">Bird</option>
<option rel="4">Car</option>
</select>
<select class="kidSelect">
<option rel="1">Banana</option>
<option rel="1">Apple</option>
<option rel="1">Orange</option>
<option rel="2">Wolf</option>
<option rel="2">Fox</option>
<option rel="2">Bear</option>
<option rel="3">Eagle</option>
<option rel="3">Hawk</option>
<option rel="4">BWM</option>
</select>
<select class="kidSelect">
<option rel="1">AAAAA</option>
<option rel="2">BBBBB</option>
<option rel="3">CCCCC</option>
</select>
You need to treat each of the kidSelect individually. Loop through each of them at the beginning and store a clone of their own options in each instance.
Then when you change main select, filter each set separately
// store a clone of each kidSelect options on page load
$('.kidSelect').each(function() {
$(this).data('options', $(this).children().clone());
});
$(".mainSelect").change(function() {
var rel = this.options[this.selectedIndex].getAttribute('rel');
// filter each kids options and set in place
$('.kidSelect').html(function() {
return $(this).data('options').filter('[rel=' + rel + ']').clone();
});
// trigger the change on page load also to do initial filtering
}).change();
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<select class="mainSelect">
<option rel="1">Fruit</option>
<option rel="2">Animal</option>
<option rel="3">Bird</option>
<option rel="4">Car</option>
</select>
<select class="kidSelect">
<option rel="1">Banana</option>
<option rel="1">Apple</option>
<option rel="1">Orange</option>
<option rel="2">Wolf</option>
<option rel="2">Fox</option>
<option rel="2">Bear</option>
<option rel="3">Eagle</option>
<option rel="3">Hawk</option>
<option rel="4">BWM</option>
</select>
<select class="kidSelect">
<option rel="1">AAAAA</option>
<option rel="2">BBBBB</option>
<option rel="3">CCCCC</option>
</select>
I'm not entirely sure what you're trying to do but here is a guess.
I think you only want to effect the second select with the changes. For that you need to adjust your selector. It currently selects both selects.
$(document).ready(function () {
$(".mainSelect").change(function() {
if ($(this).data('options') === undefined) {
$(this).data('options', $('.js-kidSelect option').clone());
}
var rel = this.options[this.selectedIndex].getAttribute('rel');
var options = $(this).data('options').filter('[rel=' + rel + ']');
$('.js-kidSelect').html(options);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<select class="mainSelect">
<option rel="1">Fruit</option>
<option rel="2">Animal</option>
<option rel="3">Bird</option>
<option rel="4">Car</option>
</select>
<select class="kidSelect js-kidSelect">
<option rel="1">Banana</option>
<option rel="1">Apple</option>
<option rel="1">Orange</option>
<option rel="2">Wolf</option>
<option rel="2">Fox</option>
<option rel="2">Bear</option>
<option rel="3">Eagle</option>
<option rel="3">Hawk</option>
<option rel="4">BWM</option>
</select>
<select class="kidSelect">
<option rel="1">AAAAA</option>
<option rel="2">BBBBB</option>
<option rel="3">CCCCC</option>
</select>
Here are both select boxes, what I need is if there are values selected from both boxes, both should be displayed in the URL, something like this e.g www.example.com#135+#140
<select name="search_region" id="search_region" class="search_region">
<option value="0">All Regions</option>
<option class="level-0" value="135">HTML</option>
<option class="level-0" value="136">PHP</option>
<option class="level-0" value="137">CSS</option>
</select>
<select name="search_categories" id="search_categories" class="search_categories">
<option value="">Select Category</option>
<option class="level-0" value="140">Java</option>
<option class="level-0" value="141">Script</option>
</select>
Below is this script I'm running to display the #search_regions value in the URL, so far it works perfect. Now to be able to add the #search_categories value to that.
<script type="text/javascript">
$(function(){
$('#search_region').change(function () {
var url = $(this).val();
window.location.hash = url;
console.log('select Changed');
});
});
window.addEventListener('hashchange', fn, false);
window.onload = fn; // fire on pageload
function fn() {
$('#search_region').val(window.location.hash.replace('#', ''));
console.log("hash = " + window.location.hash);
}
</script>
Any ideas on how to do this?
It's an add on from my previously asked question
Getting the select value to display in a new browser
Build your url parameters in one step, then update the window location in another step.
That said, the location.hash is whatever param starts with a hash, I don't know how it will deal with more than one param with a hash.
Here is one way to update the URL:
$(function() {
$('#search_region,#search_categories').change(function() {
console.log(window.location.href + '#' + $('#search_region').val() + '#' + $('#search_categories').val());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="search_region" id="search_region" class="search_region">
<option value="0">All Regions</option>
<option class="level-0" value="135">HTML</option>
<option class="level-0" value="136">PHP</option>
<option class="level-0" value="137">CSS</option>
</select>
<select name="search_categories" id="search_categories" class="search_categories">
<option value="">Select Category</option>
<option class="level-0" value="140">Java</option>
<option class="level-0" value="141">Script</option>
</select>
I have a list of countries like this:
The list is very extensive. I need to be able on a button click to move (focus) to the specified country.
There are many threads in StackOverflow but none of them worked. For example I tried this:
var code = 40;
$('#id_resource-regions').val(code).scrollTop(160);
There is no response and no error/warnings in the developers tool.
Note that the list is created using django forms and templates.
Select the option element you are looking for.
Get the offset top position using .offset(), of the selected option element.
Get the offset top of the select element.
Use .scrollTop() to scroll to the desired option.
Here is an example
var btn = $('button')
var select = $('select')
btn.on('click', function() {
var option = select.find("option:contains('item-30')");
var optionTop = option.offset().top
var selectTop = select.offset().top;
select.scrollTop(select.scrollTop() + (optionTop - selectTop));
option.prop('selected', true)
})

How to redirect the user on change of the selection?
html code
<select name="annee" ng-model="annee" ng-change="selectAnnee()">
<option value="2000" ng-selected="2000==2014">2012</option>
<option value="2001" ng-selected="2001==2014">2013</option>
<option value="2002" ng-selected="2002==2014">2014</option>
</select>
js code
this.selectAnnee = function(){
window.location.href=link.substring(link.indexOf('/'),link.lastIndexOf('/')) + '/fiche?type=' + this.type + '&annee=' + $scope.annee;
}
Thanks in advance!
In your controller , do this
$scope.selectAnnee = function(){
$location.path("/REDIRECT_HERE");
}
In view
<select name="annee" ng-model="annee" ng-change="selectAnnee()">
<option value="2000" >2012</option>
<option value="2001" >2013</option>
<option value="2002" >2014</option>
</select>
I have a form with 2 drop down lists on the same page using the same ids.
<select id="country">
<option value="">Any</option>
<option value="ENGLAND">England</option>
<option value="IRELAND">Ireland</option>
<option value="SCOTLAND">Scotland</option>
<option value="WALES">Wales</option>
</select>
<select id="county">
<option value="">Select a country first...</option>
</select>
<div style="clear:both"> </div>
<select id="country">
<option value="">Any</option>
<option value="ENGLAND">England</option>
<option value="IRELAND">Ireland</option>
<option value="SCOTLAND">Scotland</option>
<option value="WALES">Wales</option>
</select>
<select id="county">
<option value="">Select a country first...</option>
</select>
Not sure how to I change the JavaScript code so the second county drop down list functions same as the first one. The existing javascript and how it functions can be seen here:
http://jsfiddle.net/pfYEb/10/
You'll probably want to use class="country" instead of id="country" so that your selector will match both. (same for your id="county") In your jsfiddle, you'll also need to distinguish which county to change within your country change event. One easy way to do this is to use the index of the current element.
I've forked your jsfiddle here.
HTML
<select class="country">
<option value="">Any</option>
<option value="ENGLAND">England</option>
<option value="IRELAND">Ireland</option>
<option value="SCOTLAND">Scotland</option>
<option value="WALES">Wales</option>
</select>
<select class="county">
<option value="">Select a country first...</option>
</select>
<div style="clear:both"> </div>
<select class="country">
<option value="">Any</option>
<option value="ENGLAND">England</option>
<option value="IRELAND">Ireland</option>
<option value="SCOTLAND">Scotland</option>
<option value="WALES">Wales</option>
</select>
<select class="county">
<option value="">Select a country first...</option>
</select>
Relevant Javascript:
$('.country').change(function() {
var country = $(this).val(),
county = $('.county').eq($(".country").index(this)); // This matches the county
// Empty county dropdown
county.empty();
// Update dropdown with appropriate contents
if (country === '') {
county.append('<option value="">Select a country first...</option>');
} else {
$.each(counties[country], function(i, v) {
county.append('<option value="' + i + '">' + v + '</option>');
});
}
});
You can't really solve this querying by id. Element ID's have to be unique within a document by specification by the way. Your best shot, use classes instead.
