Javascript 选择进行部分和的筛选值

有两个班：教授和学生：

• 教授ts

• student.ts

为了将每个学生相对于老师的分数相加，我做了：

sel: number[] = []
prof: Professor[]
stud: Student[]
totalScore: number
partial: number
var: boolean = false

total() {
const total = this.stud
    .filter(c => this.sel.map(m => +m).includes(c.id))
    .reduce((a, c) => a + c.score, 0);
    this.totalScore = total
    this.var = true
}

这是页面的HTML：

{{p.name}}
{{s.name}}|

{{s.score}}
去
总计：{{totalScore}}

将总方法更改为：-

total() {
const total = this.stud
    .filter(c => this.sel.map(m => +m).includes(c.id))
    .slice(0,3)
    .reduce((a, c) => a + c.score, 0);
    this.totalScore = total
    this.variable = true
}

工作stackblitz:-

你能提供stackblitz吗？@AakashGarg是的，这是你期望的输出吗？例如，前三个选择的部分总和（丹尼尔、卢克、马克）=6+8+3=17，而不计算后续选择的总和

sel: number[] = []
prof: Professor[]
stud: Student[]
totalScore: number
partial: number
var: boolean = false

total() {
const total = this.stud
    .filter(c => this.sel.map(m => +m).includes(c.id))
    .reduce((a, c) => a + c.score, 0);
    this.totalScore = total
    this.var = true
}

total() {
const total = this.stud
    .filter(c => this.sel.map(m => +m).includes(c.id))
    .slice(0,3)
    .reduce((a, c) => a + c.score, 0);
    this.totalScore = total
    this.variable = true
}
