Question

I have a JavaScript array which contain the staff’s Chinese and English names.

Example:

XXX MA Yo-Yo

Where XXX represents the Chinese name: 馬友友.

I want to split this into two parts by using the 1st space " " as an indicator.

for (i = 0; i < /* ... */)
{
    w_temp = arr[i];
    w_name = w_temp[1].split(' ', 1);

    /* ... */
}

w_name[0] successfully returns 馬友友. But w_name[1] returns undefined, which cannot return MA Yo-Yo.

How can I split it into two parts?

Answer 1

Replace your existing w_name = ... line with something like this:

w_name = w_temp[1].split(' ');
w_name = [w_name[0], w_name.slice(1).join(' ')];

The ,1 you had earlier meant to stop parsing as soon as it came to the first space. This is not what you want; you want the part before the first space as one item and the part after as another. The new code parses all of the elements. After that, it sets it to an array consisting of:

1. The already-existing first element, and
2. The parts after the first element re-joined.
