html/java Input with Slider

I do have slider that outputs a value as text. Now I need also to build an input Textfield that does change the slider value and the slider value change the input Textfield value. I did find couple solutions, but that does not work for me, because I have comparison boxes that work hand in hand, when I try those solutions everything crashes.
Here my code:
// Term Slider
function comparisons_term_slider($settings) {
$term = str_replace('[term]',$settings['terminitial'],$settings['termoutput']);
$term = str_replace('[period]',$settings['plural'],$term);
$output = '<div class="comparisons-range comparisons-slider-term">
<div class="comparisons_slider_output">';
$output .= '<div class="output-pad"><span class="circle-down circle-control"></span><span class="output-number"><label for="loan-term">'.$settings['termlabel'].'</label> <output>'.$term.'</output><span class="circle-up circle-control"></span></div>';
$output .= '</div>
<input type="range" class="loan_term" name="loan-term" id="loan-term" min="'.$settings['termmin'].'" max="'.$settings['termmax'].'" value="'.$settings['terminitial'].'" step="'.$settings['termstep'].'" data-comparisons>
</div>';
return $output;
}
and in javascript
// Select all relevant loan slider forms
$(comparisons_loan_selector).each(function() {
// Initialize sliders
var sliders = $(this).find('[data-comparisons]'), x = $(this);
sliders.change(comparisonsCalculate);
sliders.comparisons({polyfill:false});
$('#lc_show_more').click(function() {
comparisonsShowMore.apply(this);
//comparisonsCalculate;
});
$('#sortby').change(comparisonsCalculate);
// Up and down buttons
x.find('.circle-control').click(function() {
var holder = $(this).closest('.comparisons-range'),
range = holder.find('input'),
newVal = parseFloat(range.val()),
step = parseFloat(range.attr('step')),
min = parseFloat(range.attr('min')),
max = parseFloat(range.attr('max'));
if ($(this).hasClass('circle-down')) { // reduce the slider value
newVal = newVal - step;
if (newVal > min) range.val(newVal);
else range.val(min);
} else { // raise the slider value
newVal = newVal + step;
if (newVal < max) range.val(newVal);
else range.val(max);
}
range.change();
});

any solutions possible? Do you need more code?
Already did try this but it doesnt work aswell..
<div>
<input id="rangeInput" type="range" min="0" max="200" oninput="amount.value=rangeInput.value" />
<input id="amount" type="number" value="100" min="0" max="200" oninput="rangeInput.value=amount.value" />
</div>

Use onclick on a button to start javascript

Hi there I'm pretty new to using functions and onclick actions to call javascript so I could do with some help. Basically, I've installed a plugin on WordPress which adds a button to the page in the form of a widget and once clicked it starts a script. However, I don't like their button so I'm trying to code my own but I want it to start the script like there's.
Here's the script code:
/*
* Timely BookButton plugin
* Example usage:
* var button = new timelyButton('doedayspa');
*
* Booking process can be kicked off manually by calling the start method on the button instance e.g.
* button.start();
*
*/

So how can I run this javascript when I click the button?
Any help would be greatly appreciated!

You could create a script tag automatically if the button has been clicked.
document.getElementById('myButton').addEventListener('click', () => {
const script = document.createElement("script");
script.src = 'my-other-file.js';
document.head.appendChild(script);
})
<button id="myButton">Load JS File</button>

Change the rangeslider's starting point videojs

I am using videojs in my react application. I have added rangeslider to it. There is a button near my video player which triggers the rangeslider to show up on the video player. Every thing works fine, but the rangeslider's start arrow is not at the point (time) where I clicked the button. The starting button is always at time 0:0. What I want is: say the video is playing at the current time 30:00 seconds and I clicked the show button, then rangeslider should show it's starting arrow at 30 sec only and not at o sec. I can get my current time of videojs player and pass it to rangeslider.js plugin, but I don't know where to pass it.
This is my rangeslider.js (I know it's a long code but i don't know which part of it to use to achieve the result)

And this is how rangeslider looks everytime it shows up

I use
video.currentTime
But it looks like rangeslider is using
e.currentPoint

Try to avoid triggering auto completing for the single key entry;Wait at least user enter three key board inputs.
And if your keep your key words in a static array it wont be affect to the speed of the page load.
But the size of your images, .css files, .js files will directly affect to speed of the page load.
try to compress those files and use light weight images.
And try to reduce the round trip time. In order to do that use your basic styling in your html page.
and do research in how to reduce the page load time.
and check your site with google developer page speed insights (https://developers.google.com/speed/pagespeed/insights/)
and read the tips.....

Up/Down/Left/Right keyboard navigation with jQuery?

I have a list of div's all with a set and equal height/width that are float:left so they sit next to each other and fold under if that parent is smaller than the combined with of the items.
Pretty standard.
This is to create a list of the twitter bootstrap icons, it gives something like this:
I have added next/previous keyboard navigation using the code below, however you will notice that the up/down arrow keys are mapped to call the left/right functions. What I have no idea how to do is to actually do the up/down navigation?

Perhaps something like this: http://jsfiddle.net/QFzCY/
var blocksPerRow = 4;
$("body").on("keydown", function(e){
var thisIndex = $(".selected").index();
var newIndex = null;
if(e.keyCode === 38) {
// up
newIndex = thisIndex - blocksPerRow;
}
else if(e.keyCode === 40) {
// down
newIndex = thisIndex + blocksPerRow;
}
if(newIndex !== null) {
$(".test").eq(newIndex).addClass("selected").siblings().removeClass("selected");
}
});
Basically, you set how many items there are in a row and then find the current index and subtract or add that amount to select the next element via the new index.
If you need to know how many blocks per row there are, you could do this:
var offset = null;
var blocksPerRow = 0;
$(".test").each(function(){
if(offset === null) {
offset = $(this).offset().top;
}
else if($(this).offset().top !== offset) {
return false;
}
blocksPerRow++;
});
To deal with your 'edge' cases, you could do:
if(newIndex >= $(".test").length) {
newIndex = $(".test").length - newIndex;
}

moveUp: function () {
var that = this;
var index = $(this).index();
var containerWidth = parseInt( $('.select-icon-list').innerWidth(), 10);
var iconWidth = parseInt( $('.select-icon-list > a').width(), 10);
var noOfCols = Math.floor( containerWidth / iconWidth );
var newIndex = ( (index - noOfCols) < 0 ) ? index : (index - noOfCols);
var elem = $('.select-icon-list > a')[index];
},
