javascript set dropdown value to month not working in IE11

I am using the following code to set a drop-down value to the current month, it is working in Chrome and Edge but in IE 11 the value is empty.
month = currentDate.toLocaleString(locale, {month:"short"})
document.getElementById("month").value = month
month contains the value "Jul" and is of type string, and I can set it as the value of a text box.
If I manually assign month = "Jul", it does set the value on the drop-down.

IEs toLocalString() adds some invisible Unicode characters to the string so the value of the dropdown-option and the value of month are not actually the same.
If it won't cause cross-locale compatibility issues then you can trim these characters with replace.
Alternatively, if you know the order of your dropdown list then get the month as a number and use selectedIndex
currentDate = new Date()
locale = 'en-US'
month = currentDate.toLocaleString(locale, {month:"short"})
document.getElementById("month").value = month.replace(/[^A-z]/g,'')
// Alternatively
//document.getElementById("month").selectedIndex = currentDate.getMonth();
<select name="dates" id="month">
<option value="Jan">Jan</option>
<option value="Feb">Feb</option>
<option value="Mar">Mar</option>
<option value="Apr">Apr</option>
<option value="May">May</option>
<option value="Jun">Jun</option>
<option value="Jul">Jul</option>
<option value="Aug">Aug</option>
<option value="Sep">Sep</option>
<option value="Oct">Oct</option>
<option value="Nov">Nov</option>
<option value="Dec">Dec</option>
</select>

If value in select option is lower than in second select option, then change option

I want to achieve:
If I select "16" in first select box and bigger value in second, for example "17", then in second select automatically changing to "16".
Just if value in first select box is lower than second, always change to same values, for example 16 to 16, 18 to 18.
<select id="from_age_js" name="from_age" class="select-advertise-style">
<option value="f13">13</option>
<option value="f14">14</option>
<option value="f15">15</option>
<option value="f16">16</option>
<option value="f17">17</option>
<option value="f18" selected>18</option>
<option value="f19">19</option>
<option value="f20">20</option>
</select>
—
<select id="to_age_js" name="to_age" class="select-advertise-style">
<option value="t13">13</option>
<option value="t14">14</option>
<option value="t15">15</option>
<option value="t16">16</option>
<option value="t17">17</option>
<option value="t18">18</option>
<option value="t20" selected>20+</option>
</select>

That's an easy one, in your case, with pure javascript, I would do something like this:
function checkit()
{
//Store the two dropdowns for easy reference
var fromAge = document.getElementById('from_age_js');
var toAge = document.getElementById('to_age_js');
//Verify if the toAge value is minor, to see if the conditional code will be executed
if( fromAge.options[fromAge.selectedIndex].value >
toAge.options[toAge.selectedIndex].value)
{
//In that case, match the values to be the same...
document.getElementById('to_age_js').value =
fromAge.options[fromAge.selectedIndex].value;
}
}
And you just have to add that function to where you want it to be called. I would choose to add the onchange event from Javascript within the select dropdowns. Like this:
<select id="from_age_js" name="from_age" class="select-advertise-style" onchange="checkit();">

How would I round minutes to the nearest 5 minute mark in momentjs?

Currently working on a site where I use moment.js. I want to use jquery only.
I get the current minute using:
var minute = moment().minute();
but I want to set an alarm starting at the nearest next 5 minute mark.
So say it's 8:38pm now, var minute would be 38. I'd want to set the input to a value of 40 (that is, 40 minutes)
So where my options are:
<select id="minuteID">
<option value="0">00</option>
<option value="5">05</option>
<option value="10">10</option>
<option value="15">15</option>
<option value="20">20</option>
<option value="25">25</option>
<option value="30">30</option>
<option value="35">35</option>
<option value="40">40</option>
<option value="45">45</option>
<option value="50">50</option>
<option value=55>55</option>
</select>
And I can input the item like so:
var minute = moment().minute();
$("#minuteID option[value=" + minute + "]").prop("selected", "selected");
How do I make it so that instead of finding the exact option minute, it finds it at intervals of 5 (to the nearest 5 marker).

minute = 5 * Math.round( minute / 5 );
will do as you want.

var minute = roundToFive(moment().minute());
$("#minuteID option[value=" + minute + "]").prop("selected", "selected");
function roundToFive(num) {
var temp = num%5;
if (temp<3)
return num-temp;
else
return num+5-temp;
}

TypeError: Cannot call method 'each' of null - Javascript Type error in Joomla ChronoForms

I'm trying to make a "double" drop down with Joomla ChronoForms but I'm having a Javascript error on the page when I select something from the first dropdown, here is my code:
<select id="recipe" name="recipe">
<optgroup label="test" id="ch_1">
<option value="blabla">something here</option>
<option value="blabla">something here</option>
</optgroup>
<optgroup label="test244" id="ch_2">
<option value="blabla">something here</option>
<option value="blabla">something here</option>
</optgroup>
<optgroup label="testtt" id="ch_3">
<option value="blabla">something here</option>
<option value="blabla">something here</option>
</optgroup>
<optgroup label="testt23521" id="ch_4">
<option value="blabla">something here</option>
<option value="blabla">something here</option>
</optgroup>
<optgroup label="teeesstt" id="ch_5">
<option value="blabla">something here</option>
<option value="blabla">something here</option>
</optgroup>
</select>
and the JS code is:
window.addEvent('load', function() {
var num_groups = 5;
var groups = new Array;
for ( var i = 1; i <= num_groups; i++ ) {
groups[i] = $('ch_'+i);
$('ch_'+i).remove();
}
$('chapter').value = '';
$('chapter').addEvent('change', function() {
var group_no = $('chapter').value;
if ( !group_no ) {
return;
}
$('#recipe optgroup').each(function(el) {el.remove()});
$('recipe').appendChild(groups[group_no]);
});
});
And the JS error that I receive is: TypeError: Cannot call method 'each' of null
Could you PLEASE help me with this?
Thank you
Here is the thread in the forum related to this link or link2 , maybe it can help someone find the issue, I've tried everything I can .. :( please someone

okay, if it is joomla most likely it is MooTools, not sure what version though, try to change selector
$('#recipe optgroup').each(function(el) {el.remove()});
to
$$('#recipe optgroup').each(function(el) {el.remove()});

$('chapter')
If it's not an element it is supposed to be
$('#chapter') ID OR $('.chapter') Class
$('recipe') supposed to be $('#recipe')
Also if you think this line is jQuery
$('chapter').addEvent('change', function() {
it is supposed to be
$('#chapter').on('change', function() {
I never heard of .addEvent in javascript
Supposed to be either attachEvent or eventListener in vanilla javascript

Try this: $('#recipe').find('optgroup').each
Аre you sure that at the time of each method calling the combobox already created in dom? Try to using setTimeout function
setTimeout(function(){
$('#recipe').find('optgroup').each.....
}, 1000);
