Better way of splitting and assigning many values in Javascript?
Question by Aaron
I have a for loop that cycles through the number of elements that the user has created. There are a lot of available settings in this plugin, and each element can receive it’s specific settings.
-
User settings are entered in the following format: speed_x: “1000,500 > 1000,200 > 0,0”
This controls the speed_x in/out for 3 separate elements. The > divides by object and the commas separate the in/out. -
So I can grab specific object speed_x values, I’ve split speed_x into speed_x_set (splitting by >) resulting in:
1 1000,500
2 1000,200
3 0,0`
3 Inside the loop, I grab the value by index (since it’s the object #) and split it by comma (to get speed_x_in and speed_x_out.)
for(var i=0; i<OS.numberofobjects; ++i){
OS.speed_x_on_set[i]=speed_x_set[i].split(",")[0],
OS.speed_x_off_set[i]=speed_x_set[i].split(",")[1],
...
};
Everything is assigned by object and by setting in/out correctly into the master OS settings object. T*he problem is I have many, many settings which need to be split in this fashion…* for example: delay_x_set, speed_y_set, opacity_set, etc. Their names are all based on the default setting name, with “_set” added as shown above. Hopefully this provides enough information. Thanks!

I would say to cache the split result
for(var objindex=0; objindex<OS.numberofobjects; ++objindex){
var splits = speed_x_set[objindex].split(","); //Cache the split so its does not need to be done twice
OS.speed_x_on_set[objindex] = splits[0];
OS.speed_x_off_set[objindex] = splits[1];
...
};
