copied!<p><strong>Split on "-"</strong></p> <p>Parse the string into the parts you need:</p> <pre><code>var from = $("#datepicker").val().split("-") var f = new Date(from[2], from[1] - 1, from[0]) </code></pre> <p><strong>Use regex</strong></p> <pre><code>var date = new Date("15-05-2018".replace( /(\d{2})-(\d{2})-(\d{4})/, "$2/$1/$3")) </code></pre> <p><strong>Why not use regex?</strong></p> <p>Because you know you'll be working on a string made up of three parts, separated by hyphens.</p> <p>However, if you were looking for that same string within another string, regex would be the way to go.</p> <p><strong>Reuse</strong></p> <p>Because you're doing this more than once in your sample code, and maybe elsewhere in your code base, wrap it up in a function:</p> <pre><code>function toDate(dateStr) { var parts = dateStr.split("-") return new Date(parts[2], parts[1] - 1, parts[0]) } </code></pre> <p>Using as:</p> <pre><code>var from = $("#datepicker").val() var to = $("#datepickertwo").val() var f = toDate(from) var t = toDate(to) </code></pre> <p>Or if you don't mind jQuery in your function:</p> <pre><code>function toDate(selector) { var from = $(selector).val().split("-") return new Date(from[2], from[1] - 1, from[0]) } </code></pre> <p>Using as:</p> <pre><code>var f = toDate("#datepicker") var t = toDate("#datepickertwo") </code></pre> <p><strong>Modern JavaScript</strong></p> <p>If you're able to use more modern JS, array destructuring is a nice touch also:</p> <pre><code>function toDate(dateStr) { const [day, month, year] = dateStr.split("-") return new Date(year, month - 1, day) } </code></pre>
