Several ways that JavaScript creates objects and properties

In a word, the object in JavaScript is a function, a method.

(i) the first type:

A, declared object: var jhsoft = Jhsoft | | {}; or Var jhsoft=new Object ();

b, add attribute:Jhsoft.currenturl = document. url;//Current Page

C, Add Method:

Jhsoft.trim = function (str) {//Remove spaces
if (str = = null) return "";
str = str.replace (/[\r\n]/g, "");
str = str.replace (/[]/g, "");
str = str.replace ("", "");
return $.trim (str);
};

The second type:

var jhsoft={

Currenturl:document. url,//Current Page

Trim:function (str) {//Remove spaces
if (str = = null) return "";
str = str.replace (/[\r\n]/g, "");
str = str.replace (/[]/g, "");
str = str.replace ("", "");
return $.trim (str);
};

}

The third type:

var jhsoft=new function (Currenturl)

{

This. Currenturl=currenturl,//Current page

this.trim= function (str) {//Remove spaces
if (str = = null) return "";
str = str.replace (/[\r\n]/g, "");
str = str.replace (/[]/g, "");
str = str.replace ("", "");
return $.trim (str);
};

}
