jQuery.each数组推送不起作用？

Question

I have this code:

var positions = [];
      $('.category-description TABLE TD').each(function() {
        var fulltxt = $(this).html().replace(/(<([^>]+)>)/ig,"");
        var lengt = fulltxt.length;
        var indx = $(this).index();
        positions.push[fulltxt];
        alert(positions);
      });

I can't understand why it's not working.. Table always have atleast 3 TD's and fulltxt have content. Alert(positions) returns empty result.

Answer 1

It does not work because of a typo

positions.push[fulltxt];
              ^       ^

should be

positions.push(fulltxt);
              ^       ^

And it appears you are trying to reinvent $(this).text() .

You can also use map()

var positions = $('.category-description TABLE TD')
  .map(function() {
    return $(this).text();
  })
  .get();
