I want to be able to sort by ID values and by dates, but I want to do the sorting so that the values are ordered by year. Just a regular sort of ID with a secondary date sort yields this: ID Date 0001 1 / 1 / 2010 0001 1 / 1 / 2011 0001 1 / 1 / 2012

对象方法 -最简单的绑定（这里的active加不加单引号都可以，以下也一样都能渲染） :class="{ 'active': isActive }" 判断是否绑定一个active　　 :class="{'active':isActive==-1}" 或者 :class="{'active':isActive==index}" 绑定并判断多个 第一种（用逗号隔开） :class="{ 'active': isActive, 'sort': isSort }" 第二种（放在data里面） //也可以把后面绑定的对象写在一个变量放在data里面，可以变成下面这样 :class="classObject" data() { return { classObject:{ active: true, sort:false } } } 第三种（使用computed属性） :class="classObject" data() { return { isActive: true, isSort: false } }, computed: { classObject: function () { return { active: this.isActive, sort:this.isSort } } } 数组方法 单纯数组 :class="[isActive,isSort]" data() {

The infrastructure is in the process of being decommissioned and we are left with the task of coming up with an alternative of generating the report on the data (which we imported as tab separated files into our new environment) Assuming we have a table with the following fields. Query IPAddress LocationCode Our original SQL query we used to run on Hive was (well not exactly.. but something similar) select COUNT(DISTINCT Query, IPAddress) as c1,

方式 一： 通过params 1.路由表中 　　<Route path=' /sort/:id ' component={Sort}></Route> 　　　　　　　　　　　 2.Link处 　　HTML方式 　　<Link to={ ' /sort/ ' + ' 2 ' } activeClassName='active'>XXXX</Link> 　　　　 　　　　　　　　　　　 　　JS方式 　　this.props.router.push( '/sort/'+'2' ) 　　　　　　　　　　　 3.sort页面 　　通过 this.props.params.id 就可以接受到传递过来的参数（id） 方式 二： 通过query 前提：必须由其他页面跳过来，参数才会被传递过来 　　　 注：不需要配置路由表。路由表中的内容照常：<Route path='/sort' component={Sort}></Route> 1.Link处 　　HTML方式 　　<Link to={{ pathname : ' /sort ' , query : { name : 'sunny' }}}> 　　　　　　　　　　 JS方式 　　this.props.router.push({ path : '/sort' ,query : { name: ' sunny'} }) 2.sort页面 　　取值

How do I ensure proper sort order as well as good performance ? I don't need the sort-order defined by sort=score desc,intField desc . The sort order needs to be somewhat like what will be delivered using product function of score * fieldVal as effective score for sort order. But I don't need exact product for sorting. Approximations are ok, & this is just to roughly define the sort order I need. I can see a few possible
