我如何將每個詞語替換爲這樣？

Question

var x = "Hello+world + like+ this + name,bla"; 
x = x.replace(/* RegEx */, function(x){ 
    return "*" + x + "*"; 
}); 
alert(x); // Output will be " *Hello*+*World*+*like*+*name*+*bla* "; 

我如何做到這一點用js和正則表達式

Answer 1

/[a-z]+/gi將尋找的是至少一個chracter長信的任何序列。如果該單詞可以包含數字，並且在變量名稱中包含_，則使用/\w+/g。

var x = "Hello+world + like+ this + name,bla"; 
 
x = x.replace(/[a-z]+/gi, function(x){ 
 
    return "*" + x + "*"; 
 
}); 
 
alert(x);
