splitting string values using javascript

问题

I have a string of words (item names) being passed to my front end from the database I have set up. It is all working great, but I in my table in html, I have the item name in a loop, so the item names are stuck together if there is more than one item, like so: Item name1Item name2

I am passing them through to the front end using an ejs loop, and <%= data[i].ITEMNAME %>, which passes the values from the database in that specific row. So they are always changing depending on the item name. An example: I need them like Item name1, Item name2

I have this in my script so far.

var itemNameSplit = '<%= data[i].ITEMNAME %>';
var splitResponse = itemNameSplit.split(" ");
document.write("<td>" + splitResponse + "</td>")

however, this puts a comma after every word, not the end of the item name, like so:

Item,name,1Item,name,2

when again, I need it like

Item name1, Item name2

its slipping my mind how to do this, thanks in advance for the help! much appreciated:)

回答1:

How about this

var splitResponse = itemNameSplit.split("Item").join(", Item").replace(", ", "");

回答2:

//I misread the problem - this just makes 1 comma in cycle of 2, a space

  a="Item,name,1Item,name,2"
    b=a.split(",")
    c=b.reduce((accumulator, currentValue, currentIndex, array) =>{
      return currentIndex % 2 ?(accumulator + " " +  currentValue) :(accumulator + "," +  currentValue)
    })
    
    
    console.log(c)
    //Item name,1Item name,2
