javascript - 加入数组，用引号将每个值括起来 javascript

Question

如何将数组加入字符串并同时将每个值包含在其中

'1/2/12','15/5/12'

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，您可以执行以下操作

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

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

然而，一个更酷、更简单的方法（对于没有日期的情况）方法是 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

或者用 es6 术语

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('\',\'') + '\'';
