join array enclosing each value with quotes javascript
提问by dll_onFire
How can join an array into a string and at the same time enclosing each value into this '1/2/12','15/5/12'
如何将数组加入字符串并同时将每个值包含在此 '1/2/12','15/5/12' 中
for (var i in array) {
dateArray.push(array[i].date);
}
dateString=dateArray.join('');
console.log(dateString);
回答by Juan Mendes
If your dates are already strings, you can do the following
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("','") + "'");
However, a cooler and more foolproof way (for the case with no dates) way would be Array.prototype.map
然而，一种更酷、更万无一失的方式（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
Or in es6 lingo
或者在 es6 行话中
dates.map(date => `'${date}'`).join(',');

ES6:
ES6：
var dates = ['1/2/12','15/5/12'];
var result = dates.map(d => `'${d}'`).join(',');
console.log(result);回答by Pedro L.
dateString = '\'' + dateArray.join('\',\'') + '\'';
