将变量作为具有相同字符串的索引传递将不起作用

Question

我不明白为什么这行不通。我正在VueJS 2中工作。

// This is in my data object. api_data is basically an original copy of data returned from api_call, later I use this to update my maps, etc
api_data: {}

console.log(api_data) // returns an observer object with a sub key 'Sindh'
console.log(name) // returns 'Sindh'
console.log(name == 'Sindh') // returns true
console.log(name === 'Sindh') // returns false
console.log('typeof', typeof name); // returns string
console.log('api_data', _this.api_data[name]) // returns undefined
console.log('api_data', _this.api_data['Sindh']) // returns data

console.log（api_data）// //从api调用获取数据后的输出
