This seems like a trivial question, but I am getting a strange error:
“Uncaught TypeError: t.slice is not a function”
when trying to pass a unix timestamp to my code.
var myDate = new Date(1075611600000); var format = d3.time.format("%Y").parse; //Trying to return the year. console.log(format(myDate)); //error noted above console.log(myDate); //Sun Feb 01 2004 00:00:00 GMT-0500 (EST)
Anyone see the obvious mistake I am making? Thanks in advance. I have looked at this example and I do not see what I am doing wrong. I am trying to return only the year.
format function expects a string and you pass in a
Date object which does not have
I believe this is what you want to achieve:
var format = d3.time.format("%Y-%m-%d"); console.log(format(new Date(1075611600000))); // returns a string
