I´m now beginning with programming and I need to know what text would be the value of this code. The JS code would be an "on click" event from this unfoldable list. Thanks you in advance!!
<select name="select1" data-dojo-type="dijit/form/Select">
<option value="Artesania">Artesania</option>
<option value="Banco" selected="selected">Banco</option>
<option value="Bar">Bar</option>
<option value="Bodega">Bodega</option>
<option value="Boutique">Boutique</option>
<option value="Discoteca">Discoteca</option>
var selectbox = document.getElementById('select');
selectbox.addEventListener('change', function(){
console.log(this.value);
//do whatever you want with the value
});
<select name="select1" data-dojo-type="dijit/form/Select" id='select'>
<option value="Artesania">Artesania</option>
<option value="Banco" selected="selected">Banco</option>
<option value="Bar">Bar</option>
<option value="Bodega">Bodega</option>
<option value="Boutique">Boutique</option>
<option value="Discoteca">Discoteca</option>

What I'm trying is something pretty basic, but I can't do it because the examples I see aren't anything similar to what I'm looking for.
There are 2 select, one of them you choose manually and the other dynamically changes depending on the value of the first one.
If the value of the first select is 1, that in the second one they only appear whose value is 1 as well.
I want to make it 100% JavaScript, I don't want any JQuery.
HTML.php
<select onchange="catch_value_types()" name="types" id="types">
<option value="1">Meat</option>
<option value="2">Fish</option>
<option value="3">Vegetables</option>
</select>
<select name="food" id="food">
<option value="1">Pork</option>
<option value="1">Cow</option>
<option value="1">Chicken</option>
<option value="2">Sardine</option>
<option value="2">Salmon</option>
<option value="2">Mackerel</option>
<option value="3">Spinach</option>
<option value="3">Kale</option>
<option value="3">Green peas</option>
</select>
JavaScript.js
function catch_value_types() {
var types_value_option = document.getElementById("types").value;
// What should I put here?
}
Loop through the options and hide if value doesnot match
function catch_value_types() {
const selectedValue = document.getElementById("types").value;
const select2 = document.getElementById("food");
Array.from(select2.options).forEach((node) => node.style.display = node.value === selectedValue ? "block": "none");
}
<select onchange="catch_value_types()" name="types" id="types">
<option value="1">Meat</option>
<option value="2">Fish</option>
<option value="3">Vegetables</option>
</select>
<select name="food" id="food">
<option>Please Select</option>
<option value="1">Pork</option>
<option value="1">Cow</option>
<option value="1">Chicken</option>
<option value="2">Sardine</option>
<option value="2">Salmon</option>
<option value="2">Mackerel</option>

I have multiple select topion.
And I need to show the selected values.with the data of '2,4,5;
<select id="testID" multiple="multiple">
<option value="1">test Value1</option>
<option value="2">test Value2</option>
<option value="3">test Value3</option>
<option value="4">test Value4</option>
<option value="5">test Value5</option>
<option value="6">test Value6</option>
</select>
Can I use this code to get what I need.
<script type="javascript">
$(document).ready(function() {
var val_to_select = '2,4,5';
$( '#testID' ).val( val_to_select );
)};
</script>
I need output to be like this
<select id="testID" multiple="multiple">
<option value="1">test Value1</option>
<option value="2" selected>test Value2</option>
<option value="3">test Value3</option>
<option value="4" selected>test Value4</option>
<option value="5" selected>test Value5</option>
<option value="6">test Value6</option>
</select>
you can pass the value in an array like this
$("#testID").val([1,2,3]);
JsFiddle
You can use this:
var data="1,2,4";
//Make an array
var dataarray=data.split(",");
// Set the value
$("#testID").val(dataarray);
// Then refresh
$("#testID").multiselect("refresh");
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="testID" multiple="multiple">
<option value="1">test Value1</option>
<option value="2">test Value2</option>
<option value="3">test Value3</option>
<option value="4">test Value4</option>
<option value="5">test Value5</option>
<option value="6">test Value6</option>
</select>
Also your code is not javascript but jquery.
I have the following select drop down box:
<select name="selectcourier" required>
<option value="">Please Select</option>
<option value="collection">Collection</option>
<option value="Interlink">Interlink</option>
<option value="DespatchBay">Despatch Bay</option>
<option value="International">International</option>
</select>
What I want to do is if Interlink is selected a secondary select box appears below it and disappears if it unselected and another option is chosen instead. This is the second select drop down box.
<label>Select Shipping Courier:</label>
<select name="selectcourier" required>
<option value="1">Please Select</option>
<option value="2">Next Day</option>
<option value="3">2-3 Day</option>
<option value="3">Pre 12</option>
</select>
How can I go about getting this working?
bind an event with javascript on change and insert a new element in the DOM (the second select statement) like:
(provided you have jquery)
var secondSelect="your_html_here";
$("name='selectcourier'").change(function() {
if (this.val()=='Interlink') {
$('body').append(secondSelect); }
else {
$('#secondselectid').remove();
});
customise the html and where you want to append the second select
<script>
$(function(){
$('#s1').hide();
});
function call()
{
var check=$('#s2').val();
if(check=="Interlink")
{
$('#s1').show();
}
else
{
$('#s1').hide();
}
}
</script>
<select name="selectcourier" required onchange="call();" id="s2" >
<option value="">Please Select</option>
<option value="collection">Collection</option>
<option value="Interlink">Interlink</option>
<option value="DespatchBay">Despatch Bay</option>
<option value="International">International</option>
</select>
<label>Select Shipping Courier:</label>
<select name="selectcourier" required id="s1">
<option value="1">Please Select</option>
<option value="2">Next Day</option>
<option value="3">2-3 Day</option>
<option value="3">Pre 12</option>
</select>
You can use the above code to achieve your task
Just react on the event of changing the value of the first select.
If the value equals 'Interlink' display the second select - if the value is something else hide the second select.
<select name="selectcourier" required onchange="document.getElementById('interlink_addition').style.display = (this.value=='Interlink' ? 'block' : 'none')">
<option value="">Please Select</option>
<option value="collection">Collection</option>
<option value="Interlink">Interlink</option>
<option value="DespatchBay">Despatch Bay</option>
<option value="International">International</option>
</select>
<div id="interlink_addition" style="display:none">
<label>Select Shipping Courier:</label>
<select name="selectcourier" required>
<option value="1">Please Select</option>
<option value="2">Next Day</option>
<option value="3">2-3 Day</option>
<option value="3">Pre 12</option>
</select>
</div>
you can use ajax for this. write a ajax function to show second select box and call it on onChange event of the first select Box
I have a main drop down list which contains state names, when i select each state name i need to display the city names in a select box, but the select box name should be same because when i give different select box with same name the data is not storing in sql database. so i need to load the specific city names on each state select. any option
<option value="">Select your Location</option>
<option value="CHENNAI">CHENNAI</option>
<option value="GURGAON">GURGAON</option>
</select>
<select name="site">
<option value=""> Select Site </option>
<option value="City1"> City1</option>
<option value="City2"> City2</option>
<option value="City3"> City3</option>
<option value="City3"> City3</option>
</select>
<select name="site">
<option value=""> Select Site </option>
<option value="City1"> City1</option>
</select>
Demo
You can use prop('disabled', true / false); to manage which city to choose. You should not have 2 selects with same name, so because you need them in sql I made a fix for it. Notice also in your post you miss first <select> and "City 3" comes up 2 times.
html
<select name="state" id="sel_state">
<option value="">Select your Location</option>
<option value="CHENNAI">CHENNAI</option>
<option value="GURGAON">GURGAON</option>
</select>
<select name="site" id="CHENNAI">
<option value="">Select Site</option>
<option value="City1">City1</option>
<option value="City2">City2</option>
<option value="City3">City3</option>
<option value="City4">City3</option>
</select>
<select name="site" id="GURGAON">
<option value="">Select Site</option>
<option value="City1">City1</option>
</select>
jQuery
$(function () {
$("#sel_state").change(function () {
var a = $("#sel_state option:selected").text();
if (a == 'CHENNAI') {
$('#GURGAON').prop('disabled', true);
$('#CHENNAI').prop('disabled', false);
$('#GURGAON').prop('name', 'site_ignored');
$('#CHENNAI').prop('name', 'site');
}
if (a == 'GURGAON') {
$('#CHENNAI').prop('disabled', true);
$('#GURGAON').prop('disabled', false);
$('#GURGAON').prop('name', 'site');
$('#CHENNAI').prop('name', 'site_ignored');
}
});
});
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.
