JavaScript高級分裂

Question

我不得不在JavaScript此處拆分此字符串：

hl=windows xp \"windows xp\" 

三個字。

我用：

keywords = keywords.split(/ /); 

但後來我得到了4個字：

windows 
xp 
\"windows 
xp\" 

我怎麼能拆分此字符串只是3個字？

編輯：我如何刪除\」

Answer 1

這裏有一個簡單的例子：

keywords = keywords.match(/"[^"]*"|\w+/g).map(function(val) { 
    if (val.charAt(0) == '"' && val.charAt(val.lenngth-1) == '"') { 
     val = val.substr(1, val.length-2); 
    } 
    return val; 
}); 

Answer 2

function split(s, on) { 
    var words = []; 
    var word = ""; 
    var instring = false; 
    for (var i = 0; i < s.length; i++) { 
     var c = s.charAt(i); 
     if (c == on && !instring) { 
      words.push(word); 
      word = ""; 
     } else { 
      if (c != '"') 
       word += c; 
     } 
     if (c == '"') instring = !instring; 
    } 
    if (word != '') words.push(word); //dangling word problem solved 
    return words; 
} 

和適合的OP的例子

var hl = "windows xp \"windows xp\""; 
split(hl, " "); // returns ["windows","xp","windows xp"] 

Answer 3

hl="windows xp \"windows xp\"" 

var results = hl.split(/ /); 

for(var s in results) { 
    try { 
     while (results[s].search("\"") > -1) { 
      results.splice(s, 1); 
     } 
    } catch(e) {} 
} 

var quoted = hl.match(/"[^"]*"/g); //matches quoted strings 

for(var s in quoted) { 
    results.push(quoted[s]); 
} 

//results = ["windows", "xp", ""windows xp""] 

編輯，一個內襯的使用例子：

var results = hl.match(/\w+|"[^"]*"/g).map(function(s) { 
    return s.replace(/^"+|"+$/g, "") 
});
