Question

I have a date as a string:
var mydate = "05/05/2011"
when I pass this var to a function like:
myfunction(mydate);

I alert the results and get a decimal not the string date:

function myfunction(mydate){
    alert(mydate);
}

produces :

0.0004972650422675286

how do I get it back to a date?

Answer 1

I had this problem as well (I was passing the string from codebehind on a popup to a javascript on the opener). My solution was pretty simple.

in asp.net

<asp:Label ID="foo" runat="server"/>

in javascript

foo.Text = "5/5/2011";

in codebehind:

string runThis = "blahblah"
+ "'"
+ foo.Text
+ "';";

Without the single-quote surrounding the text it would spit out the decimal jibberish (ie the mathematical result of 5 / 5 / 2011)

I’m guessing in your situation you could do

alert("'" + myDate + "'");
