У меня есть файл CSV, хранящийся на моем сервере, и я хотел бы, чтобы он анализировал мой код JavaScript на клиенте.
В настоящее время у меня есть следующее, которое не работает:
function CSVToArray(strData, strDelimiter) {
// Check to see if the delimiter is defined. If not,
// then default to comma.
strDelimiter = (strDelimiter || ",");
// Create a regular expression to parse the CSV values.
var objPattern = new RegExp(
(
// Delimiters.
"(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +
// Quoted fields.
"(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +
// Standard fields.
"([^\"\\" + strDelimiter + "\\r\\n]*))"
),
"gi"
);
// Create an array to hold our data. Give the array
// a default empty first row.
var arrData = [
[]
];
// Create an array to hold our individual pattern
// matching groups.
var arrMatches = null;
// Keep looping over the regular expression matches
// until we can no longer find a match.
while (arrMatches = objPattern.exec(strData)) {
// Get the delimiter that was found.
var strMatchedDelimiter = arrMatches[1];
// Check to see if the given delimiter has a length
// (is not the start of string) and if it matches
// field delimiter. If id does not, then we know
// that this delimiter is a row delimiter.
if (
strMatchedDelimiter.length &&
strMatchedDelimiter !== strDelimiter
) {
// Since we have reached a new row of data,
// add an empty row to our data array.
arrData.push([]);
}
var strMatchedValue;
// Now that we have our delimiter out of the way,
// let's check to see which kind of value we
// captured (quoted or unquoted).
if (arrMatches[2]) {
// We found a quoted value. When we capture
// this value, unescape any double quotes.
strMatchedValue = arrMatches[2].replace(
new RegExp("\"\"", "g"),
"\""
);
} else {
// We found a non-quoted value.
strMatchedValue = arrMatches[3];
}
// Now that we have our value string, let's add
// it to the data array.
arrData[arrData.length - 1].push(strMatchedValue);
}
// Return the parsed data.
return (arrData);
}
var res = CSVToArray("http://x.x.x.x/uploaded-img/location.csv", ",");
console.log(res);
Результат: ["http://x.x.x.x/uploaded-img/location.csv"]
So basically it displays the url since the first parameter were suppose to be the actual content of CSV and not the file location.
My question how do I get the content of the csv so then I can parse it and add to some array.
Ожидаемый результат: массив данных содержимого из фактического CSV-файла с сервера.
Любая помощь в этом?
