How to push elements in JSON from javascript array
提问by deepak bhardwaj
I want to add javascript array values into JSON values object. The other element is also replaced my element like recipients, subject, message. I got Json like:
我想将 javascript 数组值添加到 JSON 值对象中。另一个元素也替换了我的元素，如收件人、主题、消息。我得到了 Json：
Below is my code.
下面是我的代码。
var BODY = {
"recipients": {
"values": [
]
},
"subject": title,
"body": message
}
var values = [];
for (var ln = 0; ln < names.length; ln++) {
var item1 = {
"person": {
"_path": "/people/"+names[ln],
},
};
values.push(item1);
}
BODY = JSON.stringify({values: values});
alert(BODY);

I think you want to make objects from array and combine it with an old object (BODY.recipients.values), if it's then you may do it using $.extent(because you are using jQuery/tagged) method after prepare the object from array
我认为您想从数组中创建对象并将其与旧对象（BODY.recipients.values）结合，如果是这样，那么您可以在从数组中准备对象后使用$.extent（因为您正在使用jQuery/标记）方法来完成它
var BODY = {
"recipients": {
"values": []
},
"subject": 'TitleOfSubject',
"body": 'This is the message body.'
}
var values = [],
names = ['sheikh', 'muhammed', 'Answer', 'Uddin', 'Heera']; // for testing
for (var ln = 0; ln < names.length; ln++) {
var item1 = {
"person": { "_path": "/people/"+names[ln] }
};
values.push(item1);
}
// Now merge with BODY
$.extend(BODY.recipients.values, values);

You can directly access BODY.values:
您可以直接访问BODY.values：
for (var ln = 0; ln < names.length; ln++) {
var item1 = {
"person": {
"_path": "/people/"+names[ln],
},
};
BODY.values.push(item1);
}

If you want to stick with the way you're populating the values array, you can then assign this array like so:
如果你想坚持填充 values 数组的方式，你可以像这样分配这个数组：
BODY.values = values;
after the loop.
循环后。
It should look like this:
它应该是这样的：
var BODY = {
"recipients": {
"values": [
]
},
"subject": title,
"body": message
}
var values = [];
for (var ln = 0; ln < names.length; ln++) {
var item1 = {
"person": {
"_path": "/people/"+names[ln],
},
};
values.push(item1);
}
BODY.values = values;
alert(BODY);
JSON.stringify() will be useful once you pass it as parameter for an AJAX call. Remember: the values array in your BODY object is different from the var values = []. You must assign that outer values[] to BODY.values. This is one of the good things about OOP.
一旦您将 JSON.stringify() 作为参数传递给 AJAX 调用，它就会很有用。请记住：您的 BODY 对象中的 values 数组与 var values = [] 不同。您必须将该外部值 [] 分配给 BODY.values。这是 OOP 的优点之一。

var arr = [ 'a', 'b', 'c'];
arr.push('d'); // insert as last item
