join数组用引号javascript包围每个值

Question

如何将数组连接成一个字符串,同时将每个值包含在'1/2/12','15/5/12'中

for (var i in array) {
    dateArray.push(array[i].date);
        }  
dateString=dateArray.join('');
console.log(dateString);

Answer 1

如果您的日期已经是字符串,则可以执行以下操作

var dates = ['1/2/12','15/5/12'];

console.log("'" + dates.join("','") + "'");

但是,更酷,更简单的方式(对于没有日期的情况)方式是 Array.prototype.map

// Array.prototype.map returns a new array by 
// mapping each element in the existing array
dates.map(function(date){
    // Wrap each element of the dates array with quotes
    return "'" + date + "'";
}).join(","); // Putsa comma in between every element

要么

dates.map(date => `'${date}'`).join(',');

Answer 2

ES6:

var dates = ['1/2/12','15/5/12'];
var result = dates.map(d => `'${d}'`).join(',');
console.log(result);

Answer 3

dateString = '\'' + dateArray.join('\',\'') + '\'';
