如何搜索文件？

So I want to be able to search a CSV file stored on the internet (google drive or google storage bucket) using a key, the CSV file will store a list of names and email addresses.

I need the function to search the CSV file using the name and find the corresponding email address and then store that email address in a variable so I can use it later on.

CSV File Format:

Project Name:               Email:
example-project-sandbox example@example.com

I have a non working attempt at this however I think this is a bit long winded and can be done a lot simpler.

$(document).ready(function() {
  $.ajax({
    type: "GET",
    url: "https://storage.googleapis.com/file.csv",
    dataType: "text",
    success: function(data) {
      processData(data);
    }
  });
});

function processData(allText) {
  var allTextLines = allText.split(/
|
/);
  var headers = allTextLines[0].split(',');
  var lines = [];

  for (var i = 1; i < allTextLines.length; i++) {
    var data = allTextLines[i].split(',');

    if (data.length == headers.length) {
      var tarr = [];

      for (var j = 0; j < headers.length; j++) {
        tarr.push(headers[j] + ":" + data[j]);
      }
      lines.push(tarr);
    }
  }
  // alert(lines);
}

Any help is greatly appreciated.

Use this library.It will really help parsing the file and save time.

Papaparse

It's very easy check this example.

// Parse CSV string
var data = Papa.parse(csv);

// Convert back to CSV
var csv = Papa.unparse(data);

// Parse local CSV file
Papa.parse(file, {
complete: function(results) {
    console.log("Email:", results.email);
}
});

If helped marked the answer and completed. :D

1) Change tarr.push(headers[j]+":"+data[j]); to tarr.push({name: headers[j], email: data[j]});

2) Loop through tarr and search for `"whatever-name"``:

var foundEmail;

for (var i = 0; i < tarr.length; i++) {
    if (tarr[i].name === "whatever-name") {
        foundEmail = tarr[i].email;
        break;  
    }
}

console.log(foundEmail);
