JS takes a different approach to script loading than traditional < script> tags. As part of that, it encourages using module IDs instead of URLs for script tags. Require. JS loads all code relative to a base. Url. The base. Url is normally set to the same directory as the script used in a data- main attribute for the top level script to load for a page. The data- main attribute is a special attribute that require. This example will end up with a base. Url of scripts: < !- -This sets the base. Url to the . If there is no explicit config and data- main is not used, then the default base. Url is the directory that contains the HTML page running Require. JS. Require. JS also assumes by default that all dependencies are scripts, so it does not expect to see a trailing . Require. JS will automatically add it when translating the module ID to a path. With the paths config, you can set. All of these capabilities allow you to use smaller strings for scripts as compared to traditional < script> tags. There may be times when you do want to reference a script directly and not conform to the . If a module ID has one of the following characteristics, the ID will not be passed through the . By doing so, it gives you more flexibility in renaming and configuring the paths to different locations for optimization builds. Similarly, to avoid a bunch of configuration, it is best to avoid deep folder hierarchies for scripts, and instead either keep all the scripts in base. Url, or if you want to separate your library/vendor- supplied code from your app code, use a directory layout like this: www/. It is recommended to store that version info in a separate text file if you want to track it, or if you use a tool like volo, it will stamp the package. This allows you to have the very minimal configuration instead of having to put an entry in the . For instance, configure . However, you may need to use some traditional/legacy . For those, you can use the shim config. To properly express their dependencies. If you do not express the dependencies, you will likely get loading errors since Require. JS loads scripts asynchronously and out of order for speed. The data- main attribute is a special attribute that require. Note: the script tag require. This means that you cannot assume that the load and execution of your data- main script will finish prior to other scripts referenced later in the same page. For example, this arrangement will fail randomly when the require. When that happens, require. For pages that want to do inline require() calls, it is best to nest those inside a require() call for the configuration: < script src=. It can explicitly list its dependencies and get a handle on those dependencies without needing to refer to global objects, but instead receive the dependencies as arguments to the function that defines the module. Modules in Require. JS are an extension of the Module Pattern, with the benefit of not needing globals to refer to other modules. The Require. JS syntax for modules allows them to be loaded as fast as possible, even out of order, but evaluated in the correct dependency order, and since global variables are not created, it makes it possible to load multiple versions of a module in a page.(If you are familiar with or are using Common. JS modules, then please also see Common. JS Notes for information on how the Require. JS module format maps to Common. JS modules). There should only be one module definition per file on disk. The modules can be grouped into optimized bundles by the optimization tool. If the module does not have any dependencies, and it is just a collection of name/value pairs, then just pass an object literal to define(): //Inside file my/shirt. The function will be called to define the module once all dependencies have loaded. The function should return an object that defines the module. The dependencies will be passed to the definition function as function arguments, listed in the same order as the order in the dependency array: //my/shirt. It depends on my/cart and my/inventory. On disk, the files are structured like this: my/cart. The function call above specifies two arguments, . These are the modules represented by the . Also, the order of the function arguments should match the order of the dependencies. The return object from the function call defines the . By defining modules in this way, . Any valid return value from a function is allowed. Here is a module that returns a function as its module definition: //A module definition inside foo/title. It uses. //my/cart and my/inventory modules from before. You can use the simplified Common. JS wrapper for those cases: define(function(require, exports, module) . This does not work on some devices like the PS3 and some older Opera mobile browsers. Use the optimizer to pull out the dependencies in the array format for use on those devices. More information is available on the Common. JS page, and in the . You can explicitly name modules yourself, but it makes the modules less portable - - if you move the file to another directory you will need to change the name. It is normally best to avoid coding in a name for the module and just let the optimization tool burn in the module names. The optimization tool needs to add the names so that more than one module can be bundled in a file, to allow for faster loading in the browser. One module per file.: Only one module should be defined per Java. Script file, given the nature of the module name- to- file- path lookup algorithm. You shoud only use the optimization tool to group multiple modules into optimized files. Relative module names inside define(): For require(. So for relative name references, those are resolved relative to the module name making the reference, then that module name, or ID, is converted to a path if needs to be loaded. Example code for a 'compute' package that has a 'main' and 'extras' modules in it: * lib/. When it asks for './extras', that is resolved relative to 'compute', so 'compute/./extras', which normalizes to just 'extras'. Since there is no paths config for that module name, the path generated will be for 'lib/extras. For this case, packages config is a better option, since it allows setting the main module up as 'compute', but internally the loader will store the module with the ID of 'compute/main' so that the relative reference for './extras' works. Another option is to construct a module at lib/compute. If using a relative path, like './module/name', those only work inside define. If you define a circular dependency (. Circular dependencies are rare, and usually a sign that you might want to rethink the design. However, sometimes they are needed, and in that case, use require() as specified above. If you are familiar with Common. JS modules, you could instead use exports to create an empty object for the module that is available immediately for reference by other modules. By doing this on both sides of a circular dependency, you can then safely hold on to the the other module. This only works if each module is exporting an object for the module value, not a function: //Inside b. However, we cannot use. However, we cannot use. It works across domains and it is an established approach to calling services that just require an HTTP GET via a script tag. To use a JSONP service in Require. JS, specify . This means you can get the value of a JSONP URL as if it was a module definition. Here is an example that calls a JSONP API endpoint. In this example, the JSONP callback parameter is called . If the JSONP service times out, it means other modules you define via define() may not get executed, so the error handling is not robust. Only JSONP return values that are JSON objects are supported. A JSONP response that is an array, a string or a number will not work. This functionality should not be used for long- polling JSONP connections - - APIs that deal with real time streaming.

Some days ago facebook released their new graph api system and updated their core structure. They also officially released php sdk so that you can easily call facebook latest graph api and old legacy api from server side by php. Before proceeding first have a look my previous article specially Facebook connect authentication part. In this post I’ll show. How to check valid session of user, if user successfully logged in. How to call graph api How to call legacy api. How to update status dynamically using graph api. How to use FQL Query. So take a look my demo of this tutorial. Please login by FBConnect and approve all the permission if you’re first time accessing the page. Follow this post based on PHP SDK 3. Facebook and skip current post. STEP 1: First download the php sdk libary from here . Now copy the facebook. STEP 2: Create a file named fbmain. And copy below code to this file. We dont know. // if it is still valid until we make an API call using the session. A session. // can become invalid if it has already expired (should not be getting the. Facebook. In the code you’ll see I included facebook. If your server has no curl extension and json extension, you’ll see error message. Until you don’t install curl and json extension this sdk will not work. It may be empty if user yet not logged in your site or user’s session is invalid. To check user’s session validity you’ve to first call an api, if user’s session is valid then the api will return result. So if $fbme is not null that means user successfully logged in via facebook and user’s session is valid. So before calling any api use conditional logic like if ($fbme) . Status id is < ?=$status. Update. First part contains php logic, api call and collection of data. Next part is html/javascript to view data (javascript for fbconnect authentication). Please change$config. And never forget to set your facebook application Connect URL. It would be your project url. In index. php I used javascript based fbconnect authentication and fbml tag. If you don’t want to use javascript for this purpose, you can generate login/logout links using php code. Generate login/logout button using this php code. How to check valid session of user, if user successfully logged in. I already discussed it in the STEP 1. So I think you already have learned how to check valid session of user. Just remember to use if ($fbme) . How to call graph api Its very simple. For http: //graph. How to call legacy api. This is almost same as of graph api calling. If you check the api() method in facebook. How to update status dynamically using graph api. Here http: //developers. Method. Description. Arguments/PROFILE. How to use FQL Query. Currently I don’t find any way to call fql query using graph api. So use the technique of legacy api calling to run fql query. Reading local files in Java. Script. Published: June 1. Comments: 0. Your browser may not support the functionality in this article. Additionally, you could use client- side logic to verify an upload's mimetype matches. The spec provides several interfaces for accessing files from a 'local' filesystem: File - an individual file; provides readonly information such as name, file size, mimetype, and a reference to the file handle. File. List - an array- like sequence of File objects. Thus, it is possible to monitor the progress of a read, catch errors. In many ways the APIs resemble XMLHttp. Request's event model. Selecting files. The first thing to do is check that your browser fully supports the File API: // Check for the various File API support. All the File APIs are supported. Try it! Using drag and drop for selecting. Another technique for loading files is native drag and drop from the desktop. We can modify the previous example slightly to include drag and drop support.< div id=. Try it! Note: Some browsers treat < input type=. When the load finishes, the reader's onload event is fired. File. Reader includes four options for reading a file, asynchronously: File. Reader. read. As. Binary. String(Blob. Every byte is represented by an integer in the range . By default the string is decoded as 'UTF- 8'. Use the optional encoding parameter. File. Reader. read. As. Data. URL(Blob. Try it! Slicing a file. In some cases reading the entire file into memory isn't the best option. One possible way to speed up the upload. The server component would then be responsible. Lucky for us, the File interface supports a slice method to support this use case. Something worth noting is that it uses the. State instead of using the. Read bytes. 1- 5. Monitoring the progress of a read. One of the nice things that we get for free when using async event handling. The onloadstart and onprogress events can be used. The example below demonstrates displaying a progress bar to monitor the status of a read.
