用双引号连接 JavaScript 数组

Question

I'm trying to join a list of latLng values which are stored in an array like this:

"48.2025,16.3687","48.2437,16.3797"

Instead, I keep getting output like this:

"48.2025,16.3687,48.2437,16.3797"

This is the code that I'm using:

$(document).ready(function()
    {

    $('#printMapLatLng').click(function()

        {
            var printPoints = [];
            for (var i in points) {
                var input = points[i].LatLng.toString();
                var output = ''+input.replace( /\s/g, "").slice(1,-1)+'';
                printPoints.push(output);
            }         
                var fullArray = printPoints.join();
                $(this).attr('href',PowerHour.getPrintUrl([fullArray]));
        });
});

Answer 1

This should help :)

var points = ["48.2025,16.3687","48.2437,16.3797"];
points.map(function(p){ return '"' + p + '"'; }).join(',');
// => '"48.2025,16.3687","48.2437,16.3797"'

Answer 2

您可以这样做以获得输出

var fullArray = "\"" + printPoints.join("\",\"") + "\"";

Answer 3

If you want single line, use this:

 const values = ["48.2025,16.3687", "48.2437,16.3797"]; console.log(values.map(value => `"${value}"`).join());
