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?
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:
You have
split(' ', 1)
The 1 means to return at most one part. You should just ommit that or change it to two if thats what you need.
Because you invoke split method with limit = 1, then w_name has only 1 item.
In addition, yours input string has 2 whitespace, therefore, if you use split without limit parameter, w_name will contains 3 items ('XXX', 'CHAN', and 'Tai-Man').
I think you should use this:
var idx = str.indexOf(' ');
if (idx != -1) {
var cn_name = str.substring(0, idx);
var en_name = str.substring(idx + 1);
}
Try this
for (var i = 0; i < arr.length; i++) {
var w_temp = arr[i];
// assuming w_temp contains an array where the second item
// is the full name string
var parts = w_temp[1].match(/^(.+?) (.+)$/);
var cn_name = parts[1];
var en_name = parts[2];
}
