javascript - 查找不带逗号的字符串

Question

我有这段代码，我在其中找到字符串值用逗号分隔的键

var db = {
    	"name": "Nkosana",
    	"middle": "Baryy",
    	"surname": "walked",
    	"batch_number": "test,b",
    	"temp": ",,67,6,87,86,5,67865,876,67",
    	"integrity": ",,,,,,,,,,,,,,,,,,,,,,,",
    	"weight": "760,765,755,758,759,758,758,769,758,762,759,7",
    	"comment": "oh la la",
    };

for (var key in db) {
  if (db.hasOwnProperty(key)) {
  	if(db[key].indexOf(',')>-1){
       console.log(key+' | ' + db[key]);
    }
  }
}

如你所见，我可以检索这些值

batch_number | test,b
temp | ,,67,6,87,86,5,67865,876,67
integrity | ,,,,,,,,,,,,,,,,,,,,,,,
weight | 760,765,755,758,759,758,758,769,758,762,759,7

现在我想知道如果有一种方法可以仅检索没有逗号的值的键

Answer 1

将 indexOf(',') > -1 更改为 indexOf(',') == -1:

var db = {
    	"name": "Nkosana",
    	"middle": "Baryy",
    	"surname": "walked",
    	"batch_number": "test,b",
    	"temp": ",,67,6,87,86,5,67865,876,67",
    	"integrity": ",,,,,,,,,,,,,,,,,,,,,,,",
    	"weight": "760,765,755,758,759,758,758,769,758,762,759,7",
    	"comment": "oh la la",
    };

for (var key in db) {
  if (db.hasOwnProperty(key)) {
  	if(db[key].indexOf(',')==-1){
       console.log(key+' | ' + db[key]);
    }
  }
}
