Answer 1

你可以使用filter方法。

var $input = $('input[type=text]').filter(function(){
   return this.value === ''
})

Answer 2

您可以使用@undefined 给出的方法。以下选择对我有用，您可以尝试：

    $(":text[value=]").get()

Answer 3

$('input:text').filter(function() { return $(this).val() == ""; });

或者

$('input:text').filter(function() { return this.value == ""; });

或者

$('input:text[value=""]');
