我想這個JSON遍歷:JSON對象屬性
{
"info":{
"version": "0.0.1",
"status": "prototype"
},
"config":{
"display_random": true,
"welcome_message": "Welcome to MagSee!",
"welcome_display_sec": 10
},
"config_form":{
"display_random":{
"label":"Display Random Image on Start",
"type": "Boolean",
"default": true
},
"welcome_message":{
"label": "Welcome Message",
"type": "TextInput",
"default": "Welcome to MagSee"
}
}
}
我從文件中讀取這個,然後分析它,並把它傳遞到翡翠的模板:
router.get('/view_config', function(req, res){
var fs = require('fs');
var file = './config.json';
var json_data = null;
var buffer = fs.readFileSync(file, 'utf8');
json_data = JSON.parse(buffer);
if (json_data == null){
console.log('Null json_data. Does the file exist?');
//todo: need to return 500/null config data message instead
return;
}
res.render('admin_view_config',{'config': json_data.config, 'config_form': json_data.config_form});
});
然後玉模板內我試圖很好地顯示屬性:
h1='Config Form'
p
ul
each object in config_form
li=object
- console.dir(object)
ul
each value, key in object
li=key+": "+value
而結果幾乎存在,但我錯過了實際名稱o F中的對象,不能圖如何獲得它:
配置表
[object Object]
label: Display Random Image on Start
type: Boolean
default: true
[object Object]
label: Welcome Message
type: TextInput
default: Welcome to MagSee
的console.dir(對象)將只顯示它的{},沒有名稱中部分(如「WELCOME_MESSAGE 「)但我不知道如何從config_form本身訪問它。
