In small projects for JavaScript use, just write a few function on the line. But in large projects, especially in the development of the pursuit of a good user experience of the site, such as SNS, will use a lot of javascrpt, sometimes the workload of JavaScript than C #, then write a bunch of function, it will appear very messy, messy, even the naming conflict, Management and maintenance are all very troublesome. In this case, we need to use object-oriented thinking to develop JavaScript. So let's just drop it:
For a project, you must first have a namespace. So the first thing we have to do is define a function to register the namespace. The code is as follows:
Copy Code code as follows:
Declares a global object registernamespace function, which is a full path to the namespace, such as "Cnblogs.blog"
registernamespace = function (fullName) {
Cut namespaces into n parts
var nsarray = Fullname.split ('. ');
var streval = "";
var strns = "";
for (var i = 0; i < nsarray.length; i++) {
if (I!= 0) {
Strns + = ".";
}
Strns + = Nsarray[i];
To create a statement that constructs a Namespace object, if it does not exist, in turn
Streval + = "If" (typeof ("+ Strns +") = = ' undefined ') "+ strns +" = new Object (); "
}
if (Streval!= "") eval (streval);
}
OK, now to register a few namespaces to try, blog Park For example, blog Park has several modules "blog", "News", "group" ...
Copy Code code as follows:
Registernamespace ("Cnblogs.blog");
Registernamespace ("Cnblogs.news");
Registernamespace ("Cnblogs.group");
In fact, the namespace here is just an object, an objects.
