推荐答案

这是答案，我从这里我的js-fiddle是这里

Here is the answer, i found this from here my js-fiddle is here

var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth();/* Returns the month (from 0-11) */
var curr_month_plus= curr_month+1; /* because if the month is  4 it will show output 3 so we have to add +1 with month*/ 
var curr_year = d.getFullYear();
function dstrToUTC(ds) {
    var dsarr = ds.split("/");
     var mm = parseInt(dsarr[0],10);
     var dd = parseInt(dsarr[1],10);
     var yy = parseInt(dsarr[2],10);
     return Date.UTC(yy,mm-1,dd,0,0,0); }
    function datediff(ds1,ds2) {
     var d1 = dstrToUTC(ds1);
     var d2 = dstrToUTC(ds2);
     var oneday = 86400000;
     return (d2-d1) / oneday;    }
    var a =curr_month_plus+ '/' + curr_date + '/' + curr_year;
    var b;   
    b = "5/26/2012";
    document.write(+datediff(a,b)+" day(s)<br>");
