javascript - jQuery 将值推送到对象中

Question

我想做的是将值推送到如下数组中:

var travellers = [['travellerUsername1', 'travellerFullname1'],['travellerUsername2', 'travellerFullname2'], ['travellerUsername3', 'travellerFullname3']]

$.each(travellers, function(index, value){
    options = [
        {label: value, title: value, value: index}
    ];
});

但如您所见，这只是将最后的数据初始化到我的选项对象中。如何将每个旅行者的值(value)推送到我的选项对象中？

Answer 1

使用Array#push方法将object压入array

var travellers = [
  ['travellerUsername1', 'travellerFullname1'],
  ['travellerUsername2', 'travellerFullname2'],
  ['travellerUsername3', 'travellerFullname3']
]
var options = [];
$.each(travellers, function(index, value) {
  options.push({
    label: value,
    title: value,
    value: index
  });
});
console.log(JSON.stringify(options, null, 4));
