[英]Call javascript function multiple times with different json-array
[英]Accessing Elements in Multiple JSON-array
我使用JSON-Simple创建了以下JSON。
题:
我如何从这个JSON数组访问“情感”,“得分”和“评论”等元素。
{
"Restaurant3": [
{
"sentiment": "positive",
"score": "0.665205",
"review": "Good Indian food in campbell that's better than average at a fair price. Will come back."
}
],
"Restaurant1": [
{
"sentiment": "positive",
"score": "0.457413",
"review": "People can say what they will about this being McIndians but I have ALWAYS had a solid meal at Tandoori Oven and was NEVER disappointed with the food.The saag lamb may be my favorite dish in the world as long as I can enjoy a cucumber salad and plenty of mint cilantro chutney to cool down my mouth. The vegetarian specials are also excellent every time. My only gripe is the menu can be a bit pricey and they have screwed around with student specials that used to get you two meals for under $10. ... Perhaps they realized it was too good of a deal?"
}
],
"Restaurant2": [
{
"sentiment": "positive",
"score": "0.684585",
"review": "We live near by and this is one of our favorite quick Indian food stop.I really like their butter chicken which is very creamy and fairly thick. The chicken inside is well spiced and grilled beforehand to give a good texture. Their baagen bharta is good as well, not as mashed up as other places and had a good mix of spice. Another thing to try is the tandoori salmon. It's juicy on the inside and crunchy on the outside. Do expect long lines during lunch, but dinner time it's fairly open."
}
]
}
我使用JSON-Simple生成此JSON-Array:
List l1 = new LinkedList(); //LinkedList.
List l2 = new LinkedList();
List l3 = new LinkedList();
JSONObject obj2 = new JSONObject(); //JSON-Simple Library
obj2.put("Restaurant1", l1); //I'm making a linked list and passing them to make nested json
obj2.put("Restaurant2", l2);
obj2.put("Restaurant3", l3);
String answer = obj2.toJSONString();
System.out.println(answer); //prints JSON
return answer; //Returning entire JSON (for now)
var yourJSON = { ... }; // your json goes here
var restaurant3sentiment = yourJSON.Restaurant3[0].sentiment;
您的JSON包含数组,因此您必须为子元素指定索引
