Question

shorten this long but basic function

Asked by: Steggs

Hello,

there must be a way to shorten this function down but its late and I cant figure it out, can you?

Basically, I have a jquery slider with two handles. I display the value of each handle above the the handle. The value for each handle is an integer. My boss wants the value converted to Month, Year. So value of 0 would = this Month, this Year. I have the months working but Im sure it can be more efficient than this...

Hope this makes sense

Thanks

// set avail between to month and year
	   function setToMonthYear() {
			var d=new Date();
			
			var firstValue = $("#availBetweenSlider").slider("values", 0);
			var theYear = d.getFullYear();
			var theMonth = d.getMonth();
			
		//	for (var a=1;a<36;a++) {
		//	 var theMonth[a] = (theMonth + [a]);
		//	}
			
			
			var theMonth1 = (d.getMonth() + 1);
			var theMonth2 = (d.getMonth() + 2);
			var theMonth3 = (d.getMonth() + 3);

			var theMonth26 = (d.getMonth() + 26);
			var theMonth27 = (d.getMonth() + 27);
			var theMonth28 = (d.getMonth() + 28);

Hi Steggs,
You can use javascript built-in function - eval() to reuse the declared variables.
The details of this function can be checked here:
http://www.w3schools.com/jsref/jsref_eval.asp

Note: You can apply it under your real environment.

eg:

// set avail between to month and year
           function setToMonthYear() {
                        var d=new Date();
                        
                        var firstValue = $("#availBetweenSlider").slider("values", 0);
                        var theYear = d.getFullYear();
                        var theMonth = d.getMonth();
                        
                      for (var a=1;a<36;a++) {
                         eval("var theMonth" + a + "=" + (d.getMonth() + a));
                      }
                        
                        
                        var month=new Array(12);
                                month[0]= 'Jan';
                                month[1]= 'Feb';

I didn't check in depth or test this, but it sounds like something like this would work:

function setToMonthYear()
{
      var d = new Date();
      var firstValue = $("#availBetweenSlider").slider("values", 0);

      var month = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug',
            'Sep', 'Oct', 'Nov', 'Dec'];

      if (firstValue < 0 || firstValue > 35)
            return;

      $("#minAvailBetweenValue").text(month[(d.getMonth()+firstValue)%12]);
}

Hi guys,

Thanks for the input. We actually went a different route and used a server side look up table to help. But I learnt from your answers

Thanks
