How to check if value starts with and ends with either of 2 options using Javascript?

I have this current if statement - which is inside a for loop:
// Validate Temperatures
if(inputs[i].name.startsWith("actual-temp") || inputs[i].name.startsWith("min-temp") || inputs[i].name.startsWith("max-temp")) {
validate(parseFloat(inputs[i].value), inputs[i], e);
}
What it does
Checks all inputs that has name starting with actual-temp, min-temp and max-temp and passes them into a function called validate
My HTML file
<input type="number" name="max-temp-1">
<input type="number" name="max-temp-1">
<input type="number" name="max-temp-1">
<input type="number" name="min-temp-1">
<input type="number" name="min-temp-1">
<input type="number" name="min-temp-1">
<input type="number" name="actual-temp-1">
<input type="number" name="actual-temp-1">
<input type="number" name="actual-temp-1">
<input type="number" name="max-temp-2">
<input type="number" name="max-temp-2">
<input type="number" name="max-temp-2">
<input type="number" name="min-temp-2">
<input type="number" name="min-temp-2">
<input type="number" name="min-temp-1">
<input type="number" name="actual-temp-2">
<input type="number" name="actual-temp-2">
<input type="number" name="actual-temp-2">
<input type="number" name="max-temp-3">
<input type="number" name="max-temp-3">
<input type="number" name="max-temp-3">
<input type="number" name="min-temp-3">
<input type="number" name="min-temp-3">
<input type="number" name="min-temp-3">
<input type="number" name="actual-temp-3">
<input type="number" name="actual-temp-3">
<input type="number" name="actual-temp-3">
Question
Within my if statement - how can I grab all elements that startsWith() (as it is in the if statement currently) and ends with either -1 or -2? Or alternatively exclude inputs names that end with -3.

You can use regular expressions for your test
if (inputs[i].name.match(/^(actual|min|max)-temp-(1|2)$/)) {
validate(parseFloat(inputs[i].value), inputs[i], e);
}

Use str.includes
if(inputs[i].name.includes("actual-temp") || inputs[i].name.includes("min-temp") || inputs[i].name.includes("max-temp")) {
validate(parseFloat(inputs[i].value), inputs[i], e);
}

for (let item of my_list) {
if (item.charAt(item.length-1)!=="3"&&
(item.startsWith("actual-temp")|| item.startsWith("min-temp")||
item.startsWith("max-temp"))
) {
//logic goes here
}
}
when the first condition in the above if loop fails , javascript will not check the 3 items in OR statements (short circuiting comes into picture)

number in input field not higher than other input field

I have two input fields in my contact form, in both fields it's only possible to fill in a number. My question is, is there a way that the number in field 1 can never be higher than the number in field 2?
I have looked everywhere but can't find a solution. Is this even possible (with Javascript)? Hopefully somebody has a solution or can send me in the right direction.
<form>
<input type="number" class="fieldone" min="0" max="16" step="0.1">
<input type="number" class="fieldtwo" min="0" max="16" step="0.1">
</form>

function forceLimit(e) {
var limit = e.target.getAttribute("max");
if(e.target.value > limit)
e.target.value = limit;
}
function handleLimitChange(e) {
var limit = e.target.value;
var fieldOne = document.querySelector('#field-one');
if(fieldOne.value > limit) {
fieldOne.value = limit;
}
fieldOne.setAttribute('max', limit);
}
<form>
<input type="number" id="field-one" class="fieldone" onchange="forceLimit(event)" min="0" max="16" step="0.1">
<input type="number" id="field-two" class="fieldtwo" onchange="handleLimitChange(event)" min="0" max="16" step="0.1">
</form>

You can use jQuery to check that always the value in field 2 is greater or equal to field 1:
$('.fieldone').change(function(){
checkValue();
});
$('.fieldtwo').change(function(){
checkValue();
});
function checkValue(){
var maxValue = $('.fieldtwo').val();
if(maxValue > 0 && $('.fieldone').val() > maxValue){
$('.fieldone').val(maxValue);
}
}

<input type="number" class="fieldtwo" min="0" max="16" step="0.1">
</form>

How to input hours and minute in angular js ?

This is code
<input type="number" class="form-control" min="0" max="12" step="1" ng-model="input.hours" required>
<input type="number" class="form-control" min="0" max="60" step="5" ng-model="input.minute" required>
This is browser preview
I need to input hours as 08 and minutes 05 But visible 8 and 5.
How can do that?
If not clear, comment. Hope answer soon.

You can use ng-change to insert a 0 before the value each time it changes:
<input type="number" class="form-control" min="0" max="12" step="1" ng-model="input.hours" required ng-change="onChange(input.hours)">
<input type="number" class="form-control" min="0" max="60" step="5" ng-model="input.minute" required ng-change="onChange(input.minute)>
$scope.onChange = function(val) {
if (val < 10) {
val = '0' + val;
}
}

I would suggest to create a filter to add '0' before number if needed

maxlength=5 not working if input type=number

This is frustrating!
When the input type is text and I gave maxlength as 5, it is not allowing me to enter more than 5 characters
<input type="text" maxlength="5" />
If I gave input type as number and I gave maxlength as 5, it is allowing more than 5 digits?
<input type="number" maxlength="5" pattern="[0-9]*" />
Am I missing something?
PS: This is for mobile responsive site!

Instead of maxlength use max
<input type="number" min="1" max="10000" />
Update
Small jQuery plugin
(function ($) {
$.fn.maxlength = function (length) {
return this.on('keydown', function () {
var maxlength = length || parseInt($(this).attr('maxlength'), 10) ;
if (maxlength && $(this).val().length >= maxlength) {
$(this).val($(this).val().slice(0, maxlength - 1));
}
});
};
}($));
Example

try using max...
<input type="number" max="99999" />
EDIT: Showing Validation
<form id='FormValidation'>
<input id="myNum" type="number" min="1" max="99999" />
<input type="text" maxlength="5" />
<input type="submit" />
</form>
Try adding a number greater than 99999 and hitting submit, check the updated fiddle.
This jquery could help too...
$('#myNum').keyup( function(e){
var max = $('#myNum').attr('max').length;
if ($(this).val().length >= max) {
$(this).val($(this).val().substr(0, max));
}
});

replace maxlength with max
// Max Length = 5
<input type="number" max="99999" />
// length between 1 to 5
<input type="number" min="1" max="99999" />

Updated Answer. It's so simple!
<input type="number" id="nbr"/>
<input type="text" maxlength="5" />
$(document).on('keypress','#nbr', function(e){
if($(this).val().length >= 5)
{
e.preventDefault();
}
});

And you can add a max attribute that will specify the highest possible number that you may insert
<input type="number" max="999" />
if you add both a max and a min value you can specify the range of allowed values:
<input type="number" min="1" max="999" />

Change html numeric min and max with javascript

changeI have two numeric inputs and would like to limit the max or min of the second one based on the changes of the first one. So....
<input id="input1" type="number" min="0" max="10" value="5" change="OnChangeNumeric()" >
<input id="input2" type="number" min="0" max="10" value="1" >
<script>
function OnChangeNumeric() {
//how to actually change the values is where i am stuck
$('#input2').max = 5;
}
</script>
how to actually change the values is where i am stuck
Thanks for your suggestions

$(function() {
$('#input1').on('change',function() {
var thisVal = this.value;
/*calculate newMin, and newMax for #input2 according to your rules
based on thisVal ........
$('#input2').attr('min', newMin).attr('max', newMax);*/
console.log( $('#input2')[0] );
});
});
No need for inline JS:
<input id="input1" type="number" min="0" max="10" value="5"/>
<input id="input2" type="number" min="0" max="10" value="1"/>
