从Axios响应中解析XML，推送到Vue数据数组 [英] Parse XML from Axios response, pushing to Vue data array

问题描述

在我的Vue应用程序中，我使用Axios获取了一个XML文件，并使用parseString将XML解析为JSON.然后，我需要将result传递给Vue数据(this.events).我的控制台日志将已解析的XML显示为Json，但无法在此函数中推送到Vue数据.

In my Vue app, I get a XML file with Axios and use parseString to parse XML as JSON. I then need to pass the result to Vue data (this.events). My console log shows the parsed XML as Json, but I cannot push to Vue data inside this function.

var parseString = require('xml2js').parseString;

axios.get(`http://url.to/events.xml`)
  .then(response => {
    parseString(response.data, function (err, result) {
      console.log(result); // returns a json array
      this.events = result // nothing happens
    });        
  })
}

如何在Vue中将JSON数组存储到this.data?

推荐答案

尽量不要在parseString中使用this，这可能是范围问题，这意味着this并未引用vue数据对象.

Try not to use this inside parseString, maybe it's a scope issue, which means this isn't referring to the vue data object.

尝试一下:

axios.get('http://url.to/events.xml')
  .then(response => {
    var self = this; 
    parseString(response.data, function (err, result) {
      self.events = result
    });        
  })
}
