jq问题处理

1、同一个事件，点击显示和隐藏

$(document).ready(function(){
    $('.container .nav-header').click(function(){
      var change = $('.container .change-link')
      $('.container .menu').slideToggle(100);

      if(change.is(':hidden'))
      {
        $(change).show();
      }else{
        $(change).hide();
      }
    })
  });

2、同一个事件，点击显示和隐藏
  $(document).ready(function(){
    var winWidth = $(window).width();
    if(winWidth<641){

      var userDown = $('nav.top-nav .menu');
      var change = $('nav.top-nav .change-link');
      userDown.hide();
      change.hide();

      $('nav.top-nav').click(function(){

        userDown.toggle();
        change.toggle();
       /* if(userDown.is(':visible'))
        {
          change.show();
        }*/
      });
    }

  });

3、jq布局左侧等于右侧高度
    $(function() {
        var _leftheight = $(".focuside").height();
        var    _rightheight = $(".g-side2").height();
        if(_leftheight > _rightheight ) {
            $(".g-side2").height(_leftheight);
        }
        else {
            $(".focuside").height(_rightheight);
        }
    })

3、点击事件开启关闭
<script>

  $(function(){
    var winWidth = $(window).width();
    if(winWidth<641) {
    $('#user .nav-list').fadeOut();
      $('#user .nav-action').click(function(){
        $('#user .nav-list').toggle(100);
      });
    }
  })

</script>
