Datepicker using Static resource

Question

I have used the below code for the compatibility of browsers for displaying the date picker and its working fine

<script src="//cdn.jsdelivr.net/webshim/1.14.5/polyfiller.js"></script>
<script>
    webshims.setOptions('forms-ext', {types: 'date'});
webshims.polyfill('forms forms-ext');
</script>
<input type="date" value="From" id="DateFrom"/> 
<input type="date"  value="To" id="DateTo"/> 
<input type="button" onclick="Search();" value="Search"/> 



    <script>
    function Search(){
        var fromdate = document.getElementById("DateFrom").value;
        var todate = document.getElementById("DateTo").value;
        alert('Date:::  ' +fromdate);
        ActionFuc(fromdate,todate);
    }

</script>

I have used this link cdn.jsdelivr.net/webshim/1.14.5/polyfiller.js and saved the javascript and used it in static resource.

By using static resource in visualforce page its not displaying the datepicker.

<apex:includeScript value="{!$Resource.DateSearch}"/>
<script>
    webshims.setOptions('forms-ext', {types: 'date'});
webshims.polyfill('forms forms-ext');
</script>

Please suggest.

Thanks in advance
