Making a different value the default using javascript

Making a different value the default using javascript - javascript

I am trying to make the default value different than what is defined in the HTML. I cannot change the HTML because it is locked by a parent company of ours. I can however change the default if I use javascript. Here is the HTML
<div class="col-md-6">
<div id="addressTypeWrapper" class="form-group">
<label for="addressListArray[0].addressTypeString">Type</label>
<select name="addressListArray[0].addressTypeString" id="addressListArray[0].addressTypeString" class="form-control" required >
<option value="Home" selected="selected">Home</option>
<option value="Office">Office</option>
<option value="Contact">Contact</option>
<option value="Other">Other</option>
<option value="Billing">Billing</option>
<option value="Purchaser">Purchaser</option>
<option value="Foreign">Foreign</option>
<option value="Agency">Agency</option>
<option value="Summer">Summer</option>
<option value="School">School</option>
<option value="Campus">Campus</option>
<option value="Temporary">Temporary</option>
<option value="Shipping">Shipping</option>
<option value="Local">Local</option>
<option value="Permanent">Permanent</option></select>
</div>
</div>
Now how would I make the Office value the default only using javascript?

Simply use that one line of javascript below to change the value on runtime
document.getElementById('addressListArray[0].addressTypeString').value = 'Office';
<div class="col-md-6">
<div id="addressTypeWrapper" class="form-group">
<label for="addressListArray[0].addressTypeString">Type</label>
<select name="addressListArray[0].addressTypeString" id="addressListArray[0].addressTypeString" class="form-control" required >
<option value="Home" selected="selected">Home</option>
<option value="Office">Office</option>
<option value="Contact">Contact</option>
<option value="Other">Other</option>
<option value="Billing">Billing</option>
<option value="Purchaser">Purchaser</option>
<option value="Foreign">Foreign</option>
<option value="Agency">Agency</option>
<option value="Summer">Summer</option>
<option value="School">School</option>
<option value="Campus">Campus</option>
<option value="Temporary">Temporary</option>
<option value="Shipping">Shipping</option>
<option value="Local">Local</option>
<option value="Permanent">Permanent</option></select>
</div>
</div>

!function(){var e=document.getElementsByTagName("option");e[0].selected=!1,e[1].selected=!0}();
<div class="col-md-6">
<div id="addressTypeWrapper" class="form-group">
<label for="addressListArray[0].addressTypeString">Type</label>
<select name="addressListArray[0].addressTypeString" id="addressListArray[0].addressTypeString" class="form-control" required>
<option value="Home" selected="selected">Home</option>
<option value="Office">Office</option>
<option value="Contact">Contact</option>
<option value="Other">Other</option>
<option value="Billing">Billing</option>
<option value="Purchaser">Purchaser</option>
<option value="Foreign">Foreign</option>
<option value="Agency">Agency</option>
<option value="Summer">Summer</option>
<option value="School">School</option>
<option value="Campus">Campus</option>
<option value="Temporary">Temporary</option>
<option value="Shipping">Shipping</option>
<option value="Local">Local</option>
<option value="Permanent">Permanent</option>
</select>
</div>
</div>

Select the dropdown and use .val(). If its a dynamic id then add another attribute like data-dropdown="list" as I have done below
$("select[data-dropdown='list']").val('Office');

Check whether selected option has no value, across multiple select fields

When I try the below jQuery, I get an error:
Unexpected Type Error (: $selReqs[i].val is not a function)
I have tried multiple variations of the below and cannot seem to get it to check if selected option has no value for each of the select fields. Any advice appreciated!
var $selReqs = $('.allMinReqs');
var reqs = [];

if(!$selReqs[i].val()) {
reqs.push($selReqs[i]);
}

The issue in your code is because you're accessing a jQuery object by index. This returns the underlying DOM Element object which has no val() method.
To achieve your goal you could use map() to create an array of all the selected values. Then you can check the length of that array to determine if anything was selected, like this:
$('button').on('click', function() {
var values = $('.allMinReqs').map((i, e) => e.value !== '' ? e.value : null).get();
console.log(values);
var somethingSelected = values.length != 0;
console.log(somethingSelected);
});

$this->db->or_like('kecamatan',$filter);
$this->db->or_like('desa_kel',$filter);
$query = $this->db->get('permo_pdrt');
return $query->result();

I use this code in javascript to calculate the difference and this difference will be 100-(select1+select2) without click any button
<script>
function calc() {
var textValue1 = document.getElementById('cpercentage').value;
var textValue2 = document.getElementById('epercentage').value;
document.getElementById('mpercentage').value = 100-(textValue1 + textValue2);
}
</script>
but i don't have any result in the input field i don't know why can any body help to solve this problem
after a search i see this in stackoverflow link
but also didn't help

Bind the change event to select elements,
document.getElementById('cpercentage').addEventListener('change', calc);
document.getElementById('epercentage').addEventListener('change', calc);
However, As you have tagged jquery, You can use
$('#cpercentage, #epercentage').on('change', calc )
window.onload = function() {
var cpercentage = document.getElementById('cpercentage');
var epercentage = document.getElementById('epercentage');
//Bind event handler
cpercentage.addEventListener('change', calc);
epercentage.addEventListener('change', calc);
function calc() {
var textValue1 = Number(cpercentage.value) || 0;
var textValue2 = Number(epercentage.value) || 0;
document.getElementById('mpercentage').value = 100 - (textValue1 + textValue2);
}
}

Hi you are getting String by using this document.getElementById('cpercentage').value
so you have to parse it into integer to perform mathematical operations.
<select id="epercentage" name="txt_epercentage" class="form-control" onchange="calc()" >
I have tried to call your function by select onchange and it is working fine
hope this will be help.

Echoing HTML select value not giving same value set

I have this html select value that I used with AngularJS in building. Anytime I print the value selected from html in php, I keep getting a different thing. Eg. I selected Computer from the select group and the value="computer", when I echo in php, I get something like this:
? string: computer ?
I can't figure what the problem is.
HTML code below
<div class="form-group" form-group-sm>
<label>Faculty/School:</label>
<select name="faculty" class="form-control" ng-model="tfaculty">

Select the dropdown and use .val(). If its a dynamic id then add another attribute like data-dropdown="list" as I have done below $("select[data-dropdown='list']").val('Office');
