How to pass array object parameter from vue website to google appscript to set google spreadsheet column value - vue.js

Question

First I create a website by vue and I pass parameter to my google appscript
vue function
var appurl = "my google appscript url"
this.$http.get(appurl, {
params: {
settingLink: this.settingLink,
albumLink: this.albumLink,
stepControl: this.stepControl,
nav: this.navSetting,
}
}).then(response => {
console.log(response);
})
and I send parameter to google appscript
my google appscript
function doGet(e) {
var params = e.parameter;
var settingLink = params.settingLink;
var albumLink = params.albumLink;
var stepControl = params.stepControl;
var nav = params.nav;
var SpreadSheet = SpreadsheetApp.openByUrl(settingLink);
var SheetName = SpreadSheet.getSheetByName("gameSetting");
SheetName.getRange("D2").setValue(stepControl);
SheetName.getRange("E2").setValue(albumLink);
SheetName.getRange("F2").setValue(nav[0].style);
SheetName.getRange("G2").setValue(nav[1].style);
SheetName.getRange("H2").setValue(nav[2].style);
}
The parameter albumLink and stepControl are string so I success push it to my spreadsheet (figure 1)
but nav is an array object like (in vue data)
nav=[
{style:"red",content:"test"},
{style:"blue",content:"test"},
{style:"green",content:"test"},
]
How could I let spreadsheet F2 as "red", G2 as "blue", and H2 as "green"

Answer 1

By checking the output of JSON.stringify(e), it seems that each property of objects become different parameters and are received as something like the following:
{
"queryString": "settingLink=settingLinkTest&albumLink=albumLinkTest&stepControl=stepControlTest&nav%5B0%5D%5Bstyle%5D=red&nav%5B0%5D%5Bcontent%5D=test&nav%5B1%5D%5Bstyle%5D=blue&nav%5B1%5D%5Bcontent%5D=test&nav%5B2%5D%5Bstyle%5D=green&nav%5B2%5D%5Bcontent%5D=test",
"contextPath": "",
"parameters": {
"nav[1][style]": [
"blue"
],
"nav[1][content]": [
"test"
],
"albumLink": [
"albumLinkTest"
],
"nav[2][style]": [
"green"
],
"settingLink": [
"settingLinkTest"
],
"nav[2][content]": [
"test"
],
"nav[0][style]": [
"red"
],
"stepControl": [
"stepControlTest"
],
"nav[0][content]": [
"test"
]
},
"contentLength": -1,
"parameter": {
"nav[2][content]": "test",
"nav[1][content]": "test",
"albumLink": "albumLinkTest",
"settingLink": "settingLinkTest",
"nav[0][style]": "red",
"stepControl": "stepControlTest",
"nav[0][content]": "test",
"nav[1][style]": "blue",
"nav[2][style]": "green"
}
}
Since the index of a particular nav and its properties become names of parameters, you can get their values by changing your doGet() to:
SheetName.getRange("F2").setValue(params["nav[0][style]"]);
SheetName.getRange("G2").setValue(params["nav[1][style]"]);
SheetName.getRange("H2").setValue(params["nav[2][style]"]);
Alternatively, as suggested in the comments of the question, you can stringify the nav object when sending it:
this.$http.get(appurl, {
params: {
settingLink: settingLink,
albumLink: albumLink,
stepControl: stepControl,
nav: JSON.stringify(nav)
}
}).then(response => {
console.log(response);
})
And then parsing when you receive it to use as you intended:
var nav = JSON.parse(params.nav);
SheetName.getRange("F2").setValue(nav[0].style);
SheetName.getRange("G2").setValue(nav[1].style);
SheetName.getRange("H2").setValue(nav[2].style);
