使用jQuery隐藏选择列表中的选项 [英] Hide options in a select list using jQuery

问题描述

我有一个对象，该对象具有要从选择列表中隐藏/删除的选项的键/值对. 以下两个选项选择器都不起作用.我想念什么?

I have an object with key/value pairs of options I want to hide/remove from a select list. Neither of the following option selectors work. What am I missing?

$.each(results['hide'], function(name, title) {                     
  $("#edit-field-service-sub-cat-value option[value=title]").hide();
  $("#edit-field-service-sub-cat-value option[@value=title]").hide();
}); 

推荐答案

就其价值而言，jQuery 1.3中不存在第二种形式(带有@).第一个不起作用，因为您显然期望变量插值.试试这个:

For what it's worth, the second form (with the @) doesn't exist in jQuery 1.3. The first isn't working because you're apparently expecting variable interpolation. Try this:

$("#edit-field-service-sub-cat-value option[value=" + title + "]").hide();

请注意，如果title包含jQuery选择器元字符，这可能会以各种丑陋的方式破坏.

Note that this will probably break in various hideous ways if title contains jQuery selector metacharacters.
