匹配第一个符合条件的项目
s代表目标字符串
pattern代表你要匹配的规则，见上面正则表格

s = "1number123xyz"
x = string.match(s,"%d+",1) --匹配数字，一次或多次匹配，从第一号位开始找
-->x = 1 --返回值是1

x = string.match(s,"%d+",2) --匹配数字，一次或多次匹配，从第二号位开始找
-->x = 123 --返回值是123

x = string.match(s,"%d+",-4) --匹配数字，一次或多次匹配，从右起第四号位开始向右找
-->x = 3

x = string.match(s,"%d+",-3) --匹配数字，一次或多次匹配，从右起第四号位开始向右找
-->x = nil

x = string.match(s,"%d*",-3) --匹配数字，零次或多次匹配，从右起第四号位开始向右找
