Making if -statement in jQuery

Question

How can you say the following in jQuery?

If If textarea AND input.title are NOT empty, then put input.button ON.

My attempt in pseudo-code

if ( $(textarea).not.empty() AND $(input.title).not.empty() ) {
   $('.ask_question').attr('enabled, 'enabled'); 
}

Answer 1

if ( $("textarea").val() != "" && $("input.title").val() != "" ) {
   $('.ask_question').attr('enabled', 'enabled'); 
}

Answer 2

if ($("#myTextArea").val().length != 0 AND $("#myTextBox").val() != 0) {
   $('.ask_question').removeAttr("disabled"); 
}

You can use "textarea" and "input[class='title']", but it is possible for these to return multiple results.

Answer 3

Not too far off.

if ( $("textarea").val().length && $("input.title").val().length ) {
  $('.ask_question').removeAttr('disabled'); 
}

Answer 4

if ( $("textarea:empty").length == 0 && $("input.title:empty").length == 0 ) {
   $('.ask_question').attr('enabled', 'enabled'); 
}

The method property length of jQuery returns the number of elements which were selected. :empty is a selector for jQuery to select elements which have no child or no text.

So,

if (number of empty textarea is 0) AND (number of empty input with the class title is 0) then
   enable somthing!

Answer 5

What would jQuery-jesus do?

$('textarea').is(":contains('')")

or

$('input.title').is(":empty")

I suppose ;)
