I have this, but it doesn't work:

var datevalue = '9999-12-31T00:00:00Z';

• Can you be a bit more specific? Are you trying to convert '9999-12-31T00:00:00Z' to a timestamp? – Ahsan Commented May 8, 2018 at 8:00
• var foo = '/Date(' + (new Date('9999-12-31T00:00:00Z')).getTime() + ')/' – Salman Arshad Commented May 8, 2018 at 8:17

I assume that you want to get the timestamp of that date. This can be achieved with the code below

var timestamp = new Date('9999-12-31T00:00:00Z').getTime()

I don't understand your question, but your code is wrong. There is no Date.parseDate() function in javascript, only Date.parse():

var datevalue = '9999-12-31T00:00:00Z'; 
var converteddate = Date.parse(datevalue);

document.getElementById('result').innerHTML = converteddate;
console.log(converteddate)

<p id="result"></p>

You can do your conversion in just three easy steps :

1. Convert your ISO 8601 string to a Date object
2. Use getTime to convert your Date object to a universal time timestamp
3. Wrap "/Date(" and ")/" around your result

Demo

function convert(iso8601string) {
  return "/Date(" + (new Date(iso8601string)).getTime() + ")/";
}

console.log(convert("2011-10-05T14:48:00.000Z"));
