如何将字符串解析为非类型

我会做一些更实用的事情。

//Define variables
var csvData = "field1a,field2a,field3a\r\nfield1b,field2b,field3b";
var linesAsObjects = [];
var lines = csvData.split(/\r\n|\n/);

//Split fields here
var splitFields = function(line){
  let fields = line.split(',');
  addItem(fields);
}

// Assign field values to object or formatting here
var addItem = function(fields){
  let obj = {};
  obj.field1 = fields[0];
  obj.field2 = fields[1];
  obj.field3 = fields[2];

  linesAsObjects.push(obj);
}

// Call the code for each line
lines.forEach(splitFields);

//Printing lines and fields as assigned to an object.
console.log(linesAsObjects);

这比“any”好得多,您可以在需要的时候键入数据。

尝试对属性使用any类型。

// add the fields you have from the CSV
class ResultFromCSV {
  myValue: any;
  otherValue: any;
}

...
let lines = csvData.split(/\r\n|\n/);
    let headers = lines[0].split(',');
    for (let i = 1; i < lines.length; i++) {
      let values = lines[i].split(',');

      // instantiate here
      let item = new ResultFromCSV();
      for (let j = 0; j < headers.length; j++) {
        item[headers[j]] = values[j];
      }
      items.push(item);
    }
    return items;
