Question

我使用的反应组件就像这样工作

<FontAwesomeIcon icon={faCoffee} />

它需要一个字体真棒图标，让它说地址簿之前添加fa，删除连字符和大写每个世界的第一个字母。

   address-book become faAddressBook
   copyright become faCopyright
   arrow-alt-circle-down become faArrowAltCircleDown

是否可以创建一个javascript函数，它采用像这样的数组

["address-book","copyright","arrow-alt-circle-down"]

并将其转换为类似

的数组

["faAddressBook","faCopyright","faArrowAltCircleDown"]

Answer 1

您可以使用数组的map()和forEach()执行以下操作：

var arr = ["address-book","copyright","arrow-alt-circle-down"];

function upperCase(string) {
  return string.charAt(0).toUpperCase() + string.slice(1);
}

var outPut = arr.map(function(item){
  var temp = item.split('-');
  var temp2 = [];
  temp.forEach(function(data){
    temp2.push(upperCase(data))
  });
  return 'fa' + temp2.join('')
})
console.log(outPut);

有一些方法可以做到这一点。喜欢使用正则表达式。但是，您的要求很简单，因此可以使用JavaScript拆分方法轻松完成。请检查以下实现的功能。

function myFunction() {
   // get all of the answers
  var form = FormApp.getActiveForm();
  var formResponses = form.getResponses();
  var data = new Array();

  for (var i = 0; i < formResponses.length; i++) {
    var formResponse = formResponses[i];
    var itemResponses = formResponse.getItemResponses();
    for (var j = 0; j < itemResponses.length; j++) {
      var itemResponse = itemResponses[j];
      var record = {};

      record.question = itemResponse.getItem().getTitle();
      record.answer = itemResponse.getResponse();
      data.push(record);
    }
  }

  // check if there was response
  if (data.length == 0)
    return

  // calculate cost based on the provided factors
  var numberOfSibling = Number(data[1].answer)

  var team = data[2].answer
  var teamCost = 1;
  if (team == 'team1')
    teamCost = 1;
  if (team == 'team2')
    teamCost = 2;
  if (team == 'team3')
    teamCost = 3;


  var fourEyesExists  = data[3].answer
  var fourEyesCost
  if (fourEyesExists == "Yes" )
    fourEyesCost = 4;
  else 
    fourEyesCost = 1;

  var cost =  25*numberOfSibling+(teamCost*2)+(fourEyesCost*12);
  // Show the price to the kid
  form.setConfirmationMessage('You are going to ask you dad to pay: $' + cost + '. May god be with you son. If your dad refused, offer to clean the dishes for: ' + cost/2 + ' days.');


  // delete the response
  form.deleteAllResponses();

}

看起来这里有两个重要步骤。首先，我们需要在每个字符串前加fa，其次，我们需要将它们从kebab-case转换为camelCase。

所以只需为每个转换编写一个函数，然后使用每个转换通过地图运行数组：

＆＃13;

const kebabs = ["address-book","copyright","arrow-alt-circle-down"];

function kebabToCamel(str) {
    return str.replace(/-(\w)/g, m => m[1].toUpperCase()); 
}

function prependFa(str) {
    return "fa-" + str;
}

console.log(kebabs.map(prependFa).map(kebabToCamel))
