Dojo cannot parse custom date time format

Question

I am attempting to use Dojo locale date parser but am having a heck of a time. Every time I do it it returns null.

I even forced a value of "test" to the variable outside of the function to eliminate an undefined variable scope, and it still returns null.

var djLastString = "test";
require(["dojo/date/locale"], function(locale) {
    djLastString = locale.parse("20180511 18", {
        datePattern: 'yyyyMMdd',
        timePattern: 'HH',
        selector: 'date'
    });
});
console.log(djLastString);

result: null

Answer 1

You want to convert string into Date so , in your case you have to specify the exact pattern that goes with your string ,

Your string is 20180511 18 so the datePattern should be yyyyMMdd HH ( H -> hours ) instead of yyyyMMdd

See below snippet

var djLastString = "test";
require(["dojo/date/locale"], function(locale) {
    djLastString = locale.parse("20180511 18", {
        datePattern: 'yyyyMMdd HH',
        timePattern: 'HH',
        selector: 'date'
    });
    
    console.log(djLastString);
    console.log(djLastString.getTime());
});

body {
  width: 100%;
  height: 100%;
  margin: 0;
}

#accContainer {
  height: 100% !important;
