将数据推入Json对象中的数组

Question

I need to push an an object into an array in in a Json file. To make it simple lets say that my Json looks like this:

var JsonObj = {
"elements" : []
}

I tried Push() method but it didnt work. tried also to assign to JsonObj.elements[0]= ... it also fails. How can i make it work?

Answer 1

Try that way, it has to work:

JsonObj.elements.push(1);

Answer 2

This is basic Javascript. nothing to do with Json or jQuery:

var jsonObj = {
"elements" : []
};

jsonObj.elements.push(1);
jsonObj.elements.push(1.5);
jsonObj.elements.push("some text");
jsonObj.elements.push({element: "some element"});
