I know there are lot of questions of this nature but I need to do this using JavaScript. I am using Dojo 1.8
and have all the attribute info in array, which looks like this:
[["name1", "city_name1", ...]["name2", "city_name2", ...]]
Any idea how I can export this to CSV
on the client side?
You can do this in native JavaScript. You'll have to parse your data into correct CSV format as so (assuming you are using an array of arrays for your data as you have described in the question):
const rows = [
["name1", "city1", "some other info"],
["name2", "city2", "more info"]
];
let csvContent = "data:text/csv;charset=utf-8,";
rows.forEach(function(rowArray) {
let row = rowArray.join(",");
csvContent += row + "\r\n";
});
or the shorter way (using arrow functions):
const rows = [
["name1", "city1", "some other info"],
["name2", "city2", "more info"]
];
let csvContent = "data:text/csv;charset=utf-8,"
+ rows.map(e => e.join(",")).join("\n");
Then you can use JavaScript's window.open
and encodeURI
functions to download the CSV file like so:
var encodedUri = encodeURI(csvContent);
window.open(encodedUri);
window.open
method. In order to achieve this, you can create a hidden <a>
DOM node and set its download
attribute as follows:
var encodedUri = encodeURI(csvContent);
var link = document.createElement("a");
link.setAttribute("href", encodedUri);
link.setAttribute("download", "my_data.csv");
document.body.appendChild(link); // Required for FF
link.click(); // This will download the data file named "my_data.csv".
