String split split()

Knowledge explanation:

The

split() method splits a string into a string array and returns this array.

Grammar:

stringObject.split(separator,limit)

Parameter description:

Note: If you use the empty string ("") as a separator, each character in the stringObject will be split.

We will split the string in different ways:

Split the string using the specified symbol, the code is as follows:

<span style="color: #0000ff;">var</span> mystr = "www.imooc.com"<span style="color: #000000;">;
document.write(mystr.split(</span>".")+"<br>"<span style="color: #000000;">);
document.write(mystr.split(</span>".", 2)+"<br>");

Run result:

<span style="color: #000000;">www,imooc,com
www,imooc</span>

Split the string into characters, the code is as follows:

document.write(mystr.split("")+"<br>"<span style="color: #000000;">);
document.write(mystr.split(</span>"", 5));

Run result:

<span style="color: #000000;">w,w,w,.,i,m,o,o,c,.,c,o,m
w,w,w,.,i</span>
