d3.js日期时间格式说明符未按预期工作

Question

I am using the below format specifier for dealing with datetime inputs in my d3.js force directed graph

    var parseDate = d3.timeFormat("%Y-%m-%d %H:%M:%S")

Below is an example of how the datetime data is in my graph. But

    console.log(parseDate('2015-1-7 13:45:54'))

gives the following output:

 0NaN-NaN-NaN NaN:NaN:NaN

Is there anything additional that needs to be done with the input?

Answer 1

What you might be looking for is d3.timeParse()

var parseDate = d3.timeParse("%Y-%m-%d %H:%M:%S")

console.log(parseDate('2015-1-7 13:45:54'))

Answer 2

I think you need timeParse or utcParse

var parseDate = d3.timeParse("%Y-%m-%d %H:%M:%S")

var parseDate = d3.utcParse("%Y-%m-%d %H:%M:%S")

Answer 3

You have to pass a Date object to the parseDate function:

var parseDate = d3.timeFormat('%Y-%m-%d %H:%M:%S');

// method 1 (month is zero-based)
console.log(parseDate(new Date(2015, 0, 7, 13, 45, 54)));

// method 2
console.log(parseDate(new Date('2015-1-7 13:45:54')));
