Question

I am trying to compare two dates using javascript with ExtJS 4.

var d= Ext.Date.parse("03/21/2012", "m/d/Y");
var comp= new Date();

if (d< comp) {
    console.log("date value provided is larger" );
} else {
    console.log("date value provided is less" );
}

When running the above example, the result I get is “date value provided is less”. However, when I change the value of d to a future date 12/21/2012, I still get the message “date value provided is less”.

I think this is because I need to format the var comp= new Date(); value so it can do the calculation.

How can I do that?

Answer 1

Both variables d and comp are objects. They are instances of Date.

EDIT: Date objects can be compared using < operator in JavaScript. Your code looks fine, it works on jsfiddle.

var d = Ext.Date.parse("03/21/2012", "m/d/Y");
var comp = new Date();

if (d < comp) {
    console.log("date value provided is larger" );
} else {
    console.log("date value provided is less" );
}

Thanks for clarifying the date comparison in the comments.
