var values=[0,1,5,10,15];
values.sort();
alert(values);// Output 0,1,10,15,5
This is because sort will call the toString method of each item For comparison, "10" is smaller than "5", so it is in front.
To sort values, you need to define a comparison function and pass the function into sort.
function compare(value1,value2){
if (value1return -1;
}else if(value1>value2){
return 1;
}else{
return 0;
}
}
var values=[0,1,5,10,15];
values.sort(compare);
alert(values);// Output 0,1,5,10,15
This is the forward direction. For the reverse direction, just exchange -1 and 1 in the comparison function and it will be ok.
