Question

1 line of JavaScript code

$.post('/blah', { comment_id: 1, description: ... });

For some reason, the call is not made as a JS call and per documentation, the post method allows for 2 more optional params, success and dataType. I would like to skip success and set dataType to script. I tried this and it gave me an error

$.post('/blah', { comment_id: 1, description: ... }, ,"script");

Answer 1

Pass null or undefined:

$.post('/blah', { comment_id: 1, description: ... }, null,"script");

// use void for undefined (because undefined can be reassigned)...
$.post('/blah', { comment_id: 1, description: ... }, void 0,"script");
