Question

鉴于以下内容：

var positionTitles []string
var positionRelationships []string
var positionInstitutions []string

positionTitles = ["Director" "Provost" "Assistant Provost"]
positionRelationships = ["Tenured Professor" "Lecturer" "Adjunct Professor"]
positionInstitutions = ["UCSC" "UCB" "USC"]

我如何构建一个如下所示的数组：

Positions :=
 [{
   PositionTitle: "Director",
   PositionRelationships: "Tenured Professor",
   PositionInstitution: "UCSC",
  },
  {
   PositionTitle: "Provost",
   PositionRelationships: "Lecturer",
   PositionInstitution: "UCB",
  },
  {
   PositionTitle: "Assistant Provost",
   PositionRelationships: "Adjunct Professor",
   PositionInstitution: "USC",
  }]

目标是迭代职位。

Answer 1

您可以创建一个类型来保存所有部分并迭代切片，以便

type Position struct {
    Title, Relationship, Institution string
}

positions := make([]Position, len(positionTitles))
for i, title := range positionTitles {
    positions[i] = Position{
        Title:        title,
        Relationship: positionRelationships[i],
        Institution:  positionInstitutions[i],
    }
}

但是，如果只需要迭代，则无需创建类型。查看for的正文。

我会创建一个包含所需信息的位置结构：

var menuItems = [ // text is not valid text
  { route: 'test1', text: <div className="sideMainNav User"><i><img src="/static/images/icons/test1.svg" alt="test1" /></i><span>test1 </span></div>, type: MenuItem.Types.LINK, payload: '#/test1' },
  { route: 'test2', text: <div className="sideMainNav"><i><img src="/static/images/icons/test2.svg" alt="test2" /></i><span>test2</span></div>, type: MenuItem.Types.LINK, payload: '#/test2' },
  { route: 'test3', text: <div className="sideMainNav"><i><img src="/static/images/icons/test3.svg" alt="test3" /></i><span>test3</span></div>, type: MenuItem.Types.LINK, payload: '#/test3' },
  { route: 'test4', text: <div style={{margin:'0px -8px',fontWeight:'bold',color:'#58595B',fontSize:'14px'}}>test4</div>, type: MenuItem.Types.LINK, payload: '#/test4' },
  { route: 'test5', text: <div style={{margin:'0px -8px',fontWeight:'bold',color:'#58595B',fontSize:'14px'}}>test5</div>, type: MenuItem.Types.LINK, payload: '#/test5' },
  { route: 'test6', text: <div style={{margin:'0px -8px',fontWeight:'bold',color:'#58595B',fontSize:'14px'}}>test6</div>, type: MenuItem.Types.LINK, payload: '#/' },
  { route: 'test7', text: <div className="sideLogout" onClick={this.logout}>test7</div> },
  { route: 'test8', text: <div className="sidenavPlink"> <a href="#/">test8</a></div> },
  { route: 'test9', text: <div className="sidenavHelplink"> <a href="#/"><span>Help</span><i><img src="/static/images/icons/test9.svg" width="16px"/></i></a></div> }
];

并创建这些结构的数组（或切片）以迭代它们。这是一个工作示例：http://play.golang.org/p/s02zfeNJ63

从Go中的切片构造数组
