how to get range slider value bootstrap code example

Example 1: price range slider bootstrap 4

<input type="range" name="range" step="50000" min="100000" max="1000000" value="" onchange="rangePrimary.value=value">
<input type="text" id="rangePrimary" />

Example 2: bootstrap range slider with 2 handles

No, the HTML5 range input only accepts one input. I would recommend you to use 
something like the jQuery UI range slider for that task.
