environment Configuration 3. Check the compiling environment 4. include necessary macros 5. Set the variables during compilation according to the Make Parameter 6. Include Android. mk to be compiled 7. Set the compilation system target: prerequisites to control the entire compilation process. The following are some explanations: With the analysis of the android compilation system architecture in the previous section, if you need to modify the android compilation system, you can not blindly find

Creating a Service:Before actual create a angular service, first create a constructor in Javascript: // constructor Function function Droidservice () { this. Name = '; } function () { returnthis. name; };Then the we want to the use of this constutor function, you need to the new an instance: var New Droidservice (); = ' R2-d2 '; Console.log (Droid.speak ());What's need to understand, where do new opration, under the hook, Javascript does tow thing for you

This article illustrates the way of communication between ANGULARJS controllers. Share to everyone for your reference, specific as follows: First, the use of the scope of the inheritance method Because the inheritance of the scope is based on JS prototype inheritance method, so there are two situations where, when the value above the scope is the base type, modifying the value above the parent scope affects the child scope, whereas modifying the child scope only affects the value of the child

Currently, the JS framework and some development kits and library classes are as follows: dojo, scriptaculous, prototype, Yui-Ext, jquery, mochikit, mootools, moo. FX Dojo (JS library and UI component ): Dojo is currently the most powerful j s framework. It defines itself on its own wiki. dojo is an open-source DHTML toolbox written in JavaScript. Dojo really wants to be a "unified" toolbox. It is not only browser-level, but also ambitious. Dojo inclu

The difference between an assembly is not only the Assembly name, but also the assembly version, the Assembly public key, and the Assembly culture. In this article, you can set the assembly version through the interface and encoding. □Set the assembly version Through Visual Studio → Right-click the project, select "properties", and select "application"→ Click "assembly information", set as follows, and click OK→ Click assemblyinfo. Cs in the properties folder of the project. You can see that

Tab menu with closing capability 8) tabPanes-this is an XP-style tabs that allows you to load or close a tab in real time. 9) Closeable Tabs module-this can also be disabled, but no function can be enabled.

Like the in operator, when the forin operator is used to traverse object attributes, the entire prototype chain is also traversed. Example 1: // Poisoning Object.prototypeObject.prototype.bar = 1;var foo = {moo: 2};for(var i in foo) { console.log(i); // prints both bar and moo} Here we should pay attention to two points. First, the for in loop will ignore the attribute set to false by enumerable. For exa

First,FJ letter matrix (moocrypt)DescriptionFew people know that cows are interested in matrices, especially the alphabet matrix. Farmer John (FJ) 's cows create a new Alphabet matrix: Find the words. For example, there is now a matrix of letters, as follows:UsopenOomaboMoomxoPqmromAs cows, they are only interested in the word "MOO". We can find 6 "MOO" in this matrix (on the same row, in the same column

hasOwnProperty function to obtain the correct result. Var foo = {hasOwnProperty: function () {return false ;}, bar: 'Here be dragons'}; foo. hasOwnProperty ('bar'); // always returns false // use the hasOwnProperty of the {} object and set it up and down to foo {}. hasOwnProperty. call (foo, 'bar'); // true HasOwnProperty is the only available method to check whether a property exists on an object. At the same time, we recommend that you always use the hasOwnProperty method when traversing obje

First example: Poisoning Object.prototype Object.prototype.bar = 1; var foo = {Moo:2}; for (var i in foo) { console.log (i);//Prints both bar and Moo } Here we pay attention to two points, one for the in loop ignores the enumerable set to false. For example, the length property of an array. Second, because for-in will traverse the entire prototype chain, it can affect performance when the pro

prototype object, let's take a look at the example: Modify Object.prototype Object.prototype.bar = 1; var foo = {Moo:2}; for (var i in foo) { console.log (i);//Output two properties: Bar and Moo } We can't change the behavior of the for in statement, so the only way to filter the results is to use the hasOwnProperty method, as follows: The foo variable is for (var i in foo) { if (
