I have a form where I am fetching two Dates from input tag. I need to validate and compare a date should always be greater than the another date. Here is javascript below :

function validateDD(gateout_plnd_dt){ var dt_pat = /^[0-9]{2}-[0-9]{2}-[0-9]{4}$/; var alpha = /^[a-zA-Z0-9\s\.\-]+$/ var int = /^[0-9.]+$/; var gateout_plnd_dt = document.getElementsByName('gateout_plnd_dt[]'); var gate_in_dt = document.getElementsByName('gate_in_dt[]'); for(var i=0,j=0; i<gateout_plnd_dt.length,j<gate_in_dt.length; i++,j++){ if(gateout_plnd_dt[i].value< gate_in_dt[j].value){ alert((gateout_plnd_dt[i].value)); alert(gate_in_dt[j].value); return false; } } }

I need to convert it from string into date object which i am unable to do so. Will be really helpful to get it done. Thanks.

Try this

for(var i=0; i<gateout_plnd_dt.length; i++){ out_date = gateout_plnd_dt[i].split("-"); in_date = gate_in_dt[i].split("-"); gateout_date = new Date(out_date[1],out_date[0],out_date[2]).getTime() gatein_date = new Date(in_date[1],in_date[0],in_date[2]).getTime() if(gateout_date < gatein_date ){ alert(gateout_plnd_dt[i]); alert(gate_in_dt[i]); return false; } }

I have edited it let me know. If that works for you.@user3445158
it works for single date input form, but not in array of input with multiple date. on checikng in Inspect element in console section, it show "'you string'.split("-"); is not a function"
what value you will have in this. gateout_plnd_dt[i].value
As per my code i am entering multiple date though gateout_plnd_dt in mysql table.I already have a date value in gate_in_dt. So gateout_plnd_dt>gate_in_dt .
each element in the list is string right.@user3445158

convert date to timestamp. I wouldn't suggest using a library for that reason.

 function datetotimestamp(date){ var date=date.split("-"); var newd=date[1]+"/"+date[0]+"/"+date[2]; return new Date(newd).getTime(); }

console.log( datetotimestamp("26-02-2012") < datetotimestamp("25-02-2012")) //returns false

to compare two or more values in array, use an extra function

var compareinarray = function(array) { for(var i = 1; i < array.length; i++) { if(datetotimestamp(array[i]) > datetotimestamp(array[i-1])) return false; } return true; } var arr = ["26-02-2012", "23-02-2012"]; var res = compareinarray(arr); console.log(res)

update the compareinarray function var, according to your case and array complexity.

This will work for single date input, but fails in array
