Functions of jquery isEmptyObject to determine whether an object is null

Copy codeThe Code is as follows:
IsEmptyObject: function (obj ){
For (var name in obj ){
Return false;
}
Return true;
}

Analysis:
1. What is an object? In javascript, an object is a combination of "key/value". To put it bluntly, it is a dataset, indicating attributes and methods.
JQuery determines whether an object is empty. It uses for name in obj to traverse the attribute name of the object. if an object has an attribute name, run return false to return the result and exit the loop. Otherwise, run return true;
