handleCounter is a simple plain jQuery input spinner plugin which enables plus and minus buttons to increment and decrement the input's numeric value.

How to use it:

1. The primary html structure for the input spinner.

<div class="handle-counter" id="handleCounter">
  <button class="counter-minus btn btn-primary">-</button>
  <input type="text" value="3">
  <button class="counter-plus btn btn-primary">+</button>
</div>

2. Style the input spinner with the following CSS snippets:

.handle-counter { overflow: hidden; }

.handle-counter .counter-minus,  .handle-counter .counter-plus,  .handle-counter input {
  float: left;
  text-align: center;
}

.handle-counter .counter-minus,  .handle-counter .counter-plus { text-align: center; }

.handle-counter input {
  width: 50px;
  border-width: 1px;
  border-left: none;
  border-right: none;
}

.btn {
  padding: 6px 12px;
  border: 1px solid transparent;
  color: #fff;
}

.btn:disabled, .btn:disabled:hover {
  background-color: darkgrey;
  cursor: not-allowed;
}

.btn-primary { background-color: #009dda; }

.btn-primary:hover, .btn-primary:focus { background-color: #0486b9; }

3. Include jQuery library and the jQuery handleCounter.js at the bottom of the webpage.

<script src="//code.jquery.com/jquery.min.js"></script>
<script src="app/js/handleCounter.js"></script>

4. Initialize the input spinner like this:

$('#handleCounter').handleCounter()

5. Set the maximum/minimum values.

$('#handleCounter').handleCounter({
  minimum: 1,
  maximize: null,
})

6. Callback functions available.

$('#handleCounter').handleCounter({
  onChange: function(){},
  onMinimum: function(){},
  onMaximize: function(){}
})
