小程序json字符串轉為對象

 

小程序里json字符串轉為對象使用JSON.parse()方法轉變無效, 看報錯提示有單引號“ ' ” 因為單引號而無效, 將單引號全改雙引號即可.

 

報錯如下:

VM11050:1 thirdScriptError
Unexpected token ' in JSON at position 1;at pages/address/address onLoad function;at api getStorage success callback function
SyntaxError: Unexpected token ' in JSON at position 1...

 

 截圖如下:

 

錯誤注釋,已改正如下:

    wx.getLocation({
            success: function (res) {
                var lng = res.longitude;
                var lat = res.latitude;
                var requestUrl = "https://apis.map.qq.com/ws/geocoder/v1/?location=" + lat + "," + lng + "&key=D6CBZ-D7PHQ-G7L54-GZJKF-B3PDK-MZBR4"
                wx.request({
                    url: requestUrl,
                    success: function (res) {
                        var province = res.data.result.address_component.province;
                        var city = res.data.result.address_component.city;
                        var district = res.data.result.address_component.district;
                        var address = res.data.result.address;

　　　　　　　　　　　　　　　　//不識別單引號,下面一行改正// var location = "{'province': '" + province + "','city':'" + city + "','district':'" + district + "','address':'" + address + "','lng':" + lng + ",'lat':" + lat + "}"

var location = "{\"province\": \"" + province + "\",\"city\":\"" + city + "\",\"district\":\"" + district + "\",\"address\":\"" + address + "\",\"lng\":\"" + lng + "\",\"lat\":\"" + lat + "\"}";
　　　　　　　　　　　　　　　　　　　　　
                        wx.setStorage({
                            key: 'location_key',
                            data: location
                        })
                    }
                })
            },
        })
    },
