jQuery 1.3.2 remove empty values

开发者 https://www.devze.com 2023-03-10 23:21 出处:网络
Hello I use this code to remove empty input text fields from my form: $(\'input:text[value=\\\"\\\"]\', \'#submForm\').remove();

Hello I use this code to remove empty input text fields from my form:

 $('input:text[value=\"\"]', '#submForm').remove();

How do I achieve the same but with empty dropdown values like the below one?

<select><option value=""></option><开发者_如何学C;/select>

I need to remove the empty dropdown with the jQuery remove();

How do I do that?

Thank you!


$('select option[value=""]').remove();

Or, you mean in between the option tag, then:

$('select option:empty').remove();

EDIT:

Okay. So you're referring to a multiple selection? Then this will do:

$('select option:not(:selected)').remove();

This will remove the options that have not been selected.

how about this (I don't think you can use it with the attributes because the value is on the option. Do you want to remove the option or the select item?

    $("select").each(function(){
      if($(this).val() == "")
         $(this).remove();
     });
