我想修改我的jquery脚本以添加一个不同的#id [英] I would like to amend my jquery script to add a different #id

问题描述

我有这个jquery代码，可在点击时将内容压低:

I have this jquery code which pushes the content down on click:

<script>
$(document).ready(function() {
  $('#showhide').click(function() {
    if($('#author-dropdown').css('display') == 'none') {
      $('#author-dropdown').slideDown();
    } else {
      $('#author-dropdown').slideUp();
    }
    return false;
  });
});
</script>

我想添加一个不同的ID.因此，可以说当脚本不显示时，用户应该看到#author-dropdown，而当display == block时，id应该是#author-dropdown-extended.我应该如何修改此脚本以使其实现?

I would like to add up a different id. So, lets say when the script is to display==none, user should see #author-dropdown and when display==block, the id should be #author-dropdown-extended. How should I amend this script to make it happen?

推荐答案

$('#author-dropdown').attr("id","author-dropdown-extended").slideDown();

，并更改以下内容以将其设置回原始状态

and also change the following to set it back to original state

$('#author-dropdown-extended').attr("id","author-dropdown").slideUp();

尽管如此，我还是会亲自尝试一下……

I would personally try something like this though...

$('#showhide').click(function() {
    if($('.author-dropdown').is(':hidden')) {
      $('.author-dropdown').slideDown().removeClass('author-dropdown').addClass('author-dropdown-extended');
    } else {
      $('.author-dropdown').slideUp().removeClass('author-dropdown-extended').addClass('author-dropdown');
    }
    return false;
  });
