在javascript中,我有兴趣将文本主体分割为数组句子,在该句子中它将忽略十进制数字(理想情况下为网站)。我已经找到了如何对句子进行操作-例如str.split(/[\.\!]+\s*|\n+\s*/)
-但不确定如何添加额外的位以忽略拆分中的十进制数字
例如,如果
str = "Hello there, the ice cream is $2.00.Toppings are extra."
会导致
["Hello there, the ice cream is $2.00", "Toppings are extra"]
这可能吗?
谢谢!
答案 0 :(得分:1)
str = "Hello there, the ice cream is $2.00.Toppings are extra.";
str.split(/[\.\!]+(?!\d)\s*|\n+\s*/); //[ 'Hello there, the ice cream is $2.00', 'Toppings are extra',]
(?!\d)
零宽度负向超前匹配d
匹配。如果先行匹配,则不匹配正则表达式,并且不分割字符串。
