Split String in Half By Word

Question

I\'m in a situation where I\'d like to take a string and split it in half, respecting words so that this string here doesn\'t get split into this str

Answer 1

This will split your string based on word count (not character count, so the exact length of each half could be quite different, depending on the placement of long & short words).

var s = "This is a string of filler text";

var pieces = s.split(" "),
    firstHalfLength = Math.round(pieces.length/2),
    str1 = "",
    str2 = "";

for (var i = 0; i < firstHalfLength; i++){
    str1 += (i!=0?" ":"") + pieces[i];
}
for (var i = firstHalfLength; i < pieces.length; i++){
    str2 += (i!=firstHalfLength?" ":"") + pieces[i];
}

document.write(s);
document.write("
"+str1);
document.write("
"+str2);

// Output
This is a string of filler text
This is a string
of filler text
