Tell me how to get data from a .txt file and compare it with what the user entered. str - what the user entered

$scope.praviloThree = function (str) { var count= 0; ///считать файл var text = "" for(var i =0; i<text.length; i++) { if(str == text)count++; } return count;

I will have to compare 123456 with str, and so on with the entire file

the data in the file looks like this

    You can get this file only by downloading it through the form, well, then split it into lines, in this case.

     $('#file_button').on('change', function (event) { var reader = new FileReader(); reader.onload = function (e) { var rows = e.target.result.split(/\r\n/); for (var i = 0; i < rows.length; i++) { // умная логика сравнения } }; reader.readAsText(event.target.files[0]); });
