使用Javascript - 如何替換隻是一個數字和字母

Question

"5 Teams 7 Players" ====> 5Teams 7Players 
"7 Individuals 8 Teams 8 Categories" ====> 7Individuals 8Teams 8Categories 

Answer 1

之間的所有空間試試這個模式(\d+)(\s+)(\w+)

Demo regex

var a="5 Teams 7 Players"; 
 
var b="7 Individuals 8 Teams 8 Categories"; 
 

 
console.log(a.replace(/(\d+)(\s+)(\w+)/g,'$1$3')) 
 
console.log(b.replace(/(\d+)(\s+)(\w+)/g,'$1$3'))

Answer 2

兩個普拉薩德的和smarx的模式可以進一步簡化。只需尋找一個數字，然後留出空間，並在更換空間上留出空間。

var a="5 Teams 7 Players"; 
 
var b="7 Individuals 8 Teams 8 Categories"; 
 

 
console.log(a.replace(/(\d) /g,'$1')) 
 
console.log(b.replace(/(\d) /g,'$1'))

輸出（如果你不想單擊運行）：

5Teams 7Players 
7Individuals 8Teams 8Categories
