Here i am facing a problem as when getting response from rails controller as json object as:
"77.576343,12.964343,77.576413,12.963679,77.575233,12.96545,77.5760913,12.9657723,77.575217,12.965333"
But i need to use this data as array for a success function in ajax as
[["77.570934", "12.964462"], ["77.57199", "12.96455"], ["77.571046", "12.964471"], ["77.572142", "12.964577"]]
How can i convert it there in ajax success function. Please help me. Thanx in advance.
You could split the string and build a new array with Array#reduce.
var string = "77.576343,12.964343,77.576413,12.963679,77.575233,12.96545,77.5760913,12.9657723,77.575217,12.965333",
array = string.split(',').reduce(function (r, a, i) {
if (!(i % 2)) r.push([]);
r[r.length - 1].push(a);
return r;
}, []);
console.log(array);Or without reduce, but with Array#forEach.
var string = "77.576343,12.964343,77.576413,12.963679,77.575233,12.96545,77.5760913,12.9657723,77.575217,12.965333",
array = [];
string.split(',').forEach(function (a, i) {
i % 2 || array.push([]);
array[array.length - 1].push(a);
});
console.log(array);
My friend "77.576343,12.964343,77.576413,12.963679,77.575233,12.96545,77.5760913,12.9657723,77.575217,12.965333" is string. Try with a javascript function split.
var x = "77.576343,12.964343,77.576413,12.963679,77.575233,12.96545,77.5760913,12.9657723,77.575217,12.965333";
var array = x.split(',');
array should be an Array with 10 positions. make an simple loop like:
var newArray = [];
var tmpArray = [];
for(var i = 0; i < array.length; i++){
tmpArray.push(array[i]);
if((i+1) % 2 === 0){
newArray.push(tmpArray);
tmpArray = [];
}
}
