I have this ddl fiddle

http://jsfiddle.net/L5z6e2ga/

In the select list i'm defaulting to october on page load llike this:  
<option selected="selected" value="10/01/2016">October</option>

Instead of hard coding it like this. How do I use date function and look up today's month and use that month to then set the selected month on the input select.

So if I launch this fiddle this month (which is October) it will default to October, but if I launch it next month. I will launch with November by default.

You've selected jQuery as a tag for your question so I assume you want to do this on the front end after the page loads. Correct?

First you need to make it easier to select the correct month from the select list by adding unique ids to each option.
                       <select id="DDLMonth1" name="DDLMonth1" class="DDLMonth1">
                           <option id="month6" value="07/01/2016">July</option>
                           <option id="month7" value="08/01/2016">August</option>
                           <option id="month8" value="09/01/2016">September</option>
                           <option id="month9" value="10/01/2016">October</option>
                           <option id="month10" value="11/01/2016">November</option>
                           <option id="month11" value="12/01/2016">December</option>
                           <option id="month0" value="01/01/2017">January</option>
                           <option id="month1" value="02/01/2017">February</option>
                           <option id="month2" value="03/01/2017">March</option>
                           <option id="month3" value="04/01/2017">April</option>
                           <option id="month4" value="05/01/2017">May</option>
                           <option id="month5" value="06/01/2017">June</option>
                       </select>

Open in new window

Then you can paste the following code at the bottom of the page to determine the current month and select it. Javascript dates use 0 (zero) for January and 11 for December.
<script type="text/ecmascript">
    var d = new Date();
    $('#month'+d.getMonth() ).prop('selected',true);
</script>

Open in new window

You could also use the values as a selector instead of adding the ids but then you'd have to deal with the leading zero.

There is no need for ids (Kim's comment) if you only use month values as shown below:
 <select id="DDLMonth1" name="DDLMonth1" class="DDLMonth1">
    <option value="7">July</option>
    <option value="8">August</option>
    <option value="9">September</option>
    <option value="10">October</option>
    <option value="11">November</option>
    <option value="12">December</option>
    <option value="1">January</option>
    <option value="2">February</option>
    <option value="3">March</option>
    <option value="4">April</option>
    <option value="5">May</option>
    <option value="6">June</option>
</select>

Open in new window


Your start up javascript  is:
<script type="text/javascript">
        var d = new Date();
	$('#DDLMonth1').val(d.getMonth()+1); //Set selected value
</script>

Open in new window


Note: The Jquery val function is very handy.
