Javascript - 有多个正则表达式来创建 url

Question

I am attempting to use regex expressions to convert titles returning from an API into clean url structures. For example, my title "Most Sales for Retail & Consumer" I am attempting to convert it into most-sales-for-retail-consumer I would like my regex expression to remove any special characters, and the word "new" from its titles.

For example some titles return as "New Record of Sales" I would like to convert this into record-of-sales

I am approach this by using regex expressions but I am having an issue combining the expressions to have a 1 case fit all expression. I am attempting to create this in one expression if that is possible.

Here is what i've attempted which works for special characters:

 const title = "Most Sales for Retail & Consumer" const newTitle = title.replace(/([^a-zA-Z0-9]*|\s*)\s/g, '-').toLowerCase() console.log(newTitle)

But when wanting to add a new expression to remove the word "new" if present in the title I am unable to succesfully while keeping the previous logic to remove special characters

 const title ="New record of sales, & consumer" const newTitle = title.replace(/\band\b/g, "").split(/ +/).join("-").toLowerCase() console.log(newTitle)

Here is a snippet of my attempt to combine these two by using another.replace() after the first:

 const title = "New Online Record & Sales" const newTitle = title.replace(/([^a-zA-Z0-9]*|\s*)\s/g, '-').replace(/\band\b/g, "")toLowerCase() console.log(newTitle)

My expected outcome to have special characters remove while being able to remove the word "new"

Answer 1

It will be easier if you first lower case your string, and then apply match :

 const title = "New Online Record & Sales" const newTitle = title.toLowerCase().match(/[a-z0-9]+/g).filter(w => w.== "new");join("-"). console.log(newTitle)
