attempting to convert String data into numerical data, the drop the data into an array of arrays (Json)
I have this:
(65.94647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)
I'm attempting to get the output to look like this:
"coords": [[65.94647177615738, 87.890625],[47.040182144806664, 90],[45.089035564831036, 122.34375]]
Any Idea?
The first result comes back to me as a string, so when i try to assign the first object to an array, the console shows me this:
array is: "(65.94开发者_Python百科647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)"
var str = "(65.94647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)";
str = str.slice(1,-1); // remove outermost parentheses
var arrCoord = str.split(')(');
for (var i=0; i<arrCoord.length; i++) {
var tarr = arrCoord[i].split(", ");
for (var j=0; j<tarr.length; j++) {
tarr[j] = parseFloat(tarr[j]);
}
arrCoord[i] = tarr;
}
// arrCoord is now populated with arrays of numbers
Decided to sort of play code golf. Assuming:
var sample = '(65.94647177615738, 87.890625)(47.040182144806664, 90)(45.089035564831036, 122.34375)';
Then:
var coords = sample
.split(/\(([^)]+)\)/)
.filter(function(v){return v!=""})
.map(function(v){return v.split(/[^0-9\.]+/)})
