[英]how to insert the element into the json array
我有這樣的json:
{
json{
"81":[
{
"name":"",
"id":""
},
{
"name":"",
"id":""
}
]
}
}
我動態地得到這個json,我將這個json存儲在adlist中。 我想將元素插入到第三個位置的數組中。 我試過這樣的:
var temp={"name":"","id":""};
adlist.json[81].splice(2,0,temp);
但它沒有正確添加字符串。
嘗試
adlist.81.push({name: "Douglas Adams", id: "comedy"});
你也可以試試這個以獲得更好的性能,
adlist.json["81"][adlist.json["81"].length] ={name: "Douglas Adams", id: "comedy"};
它對我有用:)
Java腳本代碼:
//your json data
var adlist = {json:{"81":[{"name":"first","id":"1"},{"name":"second","id":"2"}]}};
// your new json data
var temp={"name":"Third","id":"3"};
// insert your new json data in 3rd position
adlist.json["81"].push(temp);
// check with console
console.log(adlist);
