JavaScript：字符串提取

Question

If my String is like this:

var dollarValue = "$7.50;$15;50%";

What would be the best method of extracting each value? Each semicolon is used as a separator between the part of the string that matters. So like:

$7.50

$15

50%

I understand how to extract two values with only one semicolon, but I'm not sure how I would continue on down the string using each subsequent semicolon as the next starting point...

Answer 1

怎么回事String.split() ？

var arrayOfValues = dollarValue.split(";"); // ["$7.50", "$15", "50%"]

Answer 2

You can use the split method:

var values = dollarValue.split(";");

This will return an array with the values between the semicolons.
