jQuery改变兄弟元素样式,及:not([class="allclassname"])筛选小结

时间:2022-01-03 05:07:10

以前一直对于jquery感到很畏惧,最近做点击图表变色,将其他元素图片复位的小需求,总结了一下一点小心得。

主要两点是:1、将所有兄弟元素的样式设置为一样,对于子元素的遍历;

      2、对于特殊不需要变化的兄弟元素的排除;

如下,对所有兄弟元素的样式设置为一样用过有两种方法:

 <div class="paneltime">
<ul >
<li><a>今天</a></li>
<li><a>3天</a></li>
<li class="active"><a>7天</a></li>
<li><a>15天</a></li>
<li><a>30天</a></li>
<li>时间段:</li>
<li style="margin-left:200px;" ordertype="desc"><a>声量 <i class="icon-chevron-down"></i></a></li>
<li ordertype="desc"><a>时间 <i class="icon-chevron-down"></i></a></li>
<li ordertype="desc"><a>相关度 <i class="icon-chevron-down"></i></a></li>
<li class="pull-right">
<div class="panel-search bgwhite" id="panel-search">
<form class="form-search">
<span class="input-icon">
<input type="text" placeholder="搜索 ..." class="panel-search-input" id="panel-search-input" autocomplete="off" />
<i class="icon-search nav-search-icon"></i>
</span>
</form>
</div>
</li>
</ul> </div>

html部分代码

1.1、遍历子元素:

$(".paneltime li").click(function(){

  var liParent = $(this).parent();
  var brother = liParent.children();

  var orderType = $(this).attr('orderType');

    brother.each(function(index){
     $(this).removeClass('active');
    })
    $(this).addClass('active');

});

1.2、后来发现不需要遍历的:

brother.removeClass('active');
$(this).addClass('active');

2.排除最后的那个搜索图标<i class="icon-search nav-search-icon"></i>,不需要变化,不排除就会变为箭头

brother.find('i:not([class="icon-search nav-search-icon"])').attr('class','icon-chevron-down')
$(this).find('i:not([class="icon-search nav-search-icon"])').attr('class','icon-chevron-up red');

 <script type="text/javascript">
//更改当前标签的背景色 $(".paneltime li").click(function(){ var liParent = $(this).parent();
var brother = liParent.children(); var orderType = $(this).attr('orderType');
if(orderType=="desc")
{
brother.each(function(index){
$(this).removeClass('active');
})
$(this).addClass('active');
$(this).attr('orderType','asc');
brother.find('i:not([class="icon-search nav-search-icon"])').attr('class','icon-chevron-down')
$(this).find('i:not([class="icon-search nav-search-icon"])').attr('class','icon-chevron-up red');
}
else if(orderType=="asc")
{
brother.each(function(index){
$(this).removeClass('active');
})
$(this).addClass('active');
$(this).attr('orderType','desc');
brother.find('i:not([class="icon-search nav-search-icon"])').attr('class','icon-chevron-down');
$(this).find('i:not([class="icon-search nav-search-icon"])').attr('class','icon-chevron-down red');
}
else
{
brother.removeClass('active');
$(this).addClass('active');
}
});
</script>

排除后搜索按钮不会变化:
