    Including Custom Javascript Files

    TClientScriptLoader

    + + + + + +

    +The TClientScriptLoader publish a collection of javascript files as assets. +For example, suppose we have a directory name "mylib" in +the protected/pages directory of our application.

    + +assets/ +protected/ + pages/ + mylib/ + file1.js + file2.js + file3.js + file4.js + packages.php + + +

    The PackagePath property can be an existing asset directory +or a namespace path to the directory containing javascript files. +For example, to publish the javascript files in the mylib +directory, we can specify the PackagePath as follows. +The first tag TClientScriptLoader relies on the asset template tag and +assumes that the page template containing the TClientScriptLoader tag instance +is in the protected/pages directory. +The second TClientScriptLoader tag uses the namespace notation to +specify the path. +

    + + +<com:TClientScriptLoader PackagePath=<%~ mylib %> /> +<com:TClientScriptLoader PackagePath="Application.pages.mylib" /> + + +

    +When the files in the PackagePath are published as assets, a script loader + php file "clientscripts.php" is automatically copied + to that asset directory. + The script loader, combines multiple javascript files and serve up as gzip if possible. +

    +

    Grouping Javascript Files

    +

    +Allowable scripts and script dependencies can be grouped by using a "packages.php" file +with the following format. This "packages.php" is optional, if absent the file names +without ".js" extension are used. The "packages.php" must be in the directory given by +PackagePath. +

    + + +<?php + $packages = array( + 'package1' => array('file1.js', 'file2.js'), + 'package2' => array('file3.js', 'file4.js')); + + $deps = array( + 'package1' => array('package1'), + 'package2' => array('package1', 'package2')); //package2 requires package1 first. + + return array($packages,$deps); //must return $packages and $deps in an array +?> + + +

    The first element of the array returned by the packages.php should +contain an array of javascripts files relative to the packages.php +that corresponds to a particular grouping. For example, in the above packages.php, +the grouping 'package1' combines two javascript files, namely, 'file1.js' +and 'file2.js'. +

    + +

    The second element of the array returned by the packages.php should +contain an array of grouping dependencies ordered in the way that the groups should be combined. +For example, grouping 'package1' only depends on the 'package1' grouping files +(i.e. 'file1.js' and 'file2.js'). While 'package2' depends +on both 'package1' and 'package2' groupings. That is, 'package2' +will combine, in order, 'file1.js', 'file2.js', 'file3.js', and 'file4.js'. +

    + +

    Loading Javascript Packages

    + +

    To load a particular javascript file or package, set the PackageScripts +property with value 'package1' to load the 'package1' scripts. +A maximum of 25 packages separated by commas is allowed. +Dependencies of the packages are automatically resolved by the script loader php file. +

    + + +<com:TClientScriptLoader PackagePath=<%~ mylib %> PackageScripts="package2" /> +<script type="text/javascript"> + //javascript code utilizing javascript code loaded in 'package2' above +</script> + + +

    Each <com:TClientScriptLoader> generates an HTML <script> +element to load the required javascript files.

    + +

    Removing Javascript Comments

    +

    The DebugMode property when false +removes comments and white spaces from the published javascript files. If +the DebugMode property is not set, the debug mode is determined from the +application mode. +

    +
    Note: +If the DebugMode is false either explicitly or when the application mode is non-debug, +then cache headers are also sent to inform the browser and proxies to cache the file. +Moreover, the post-processed (comments removed and zipped) are saved in the assets +directory for the next requests. That is, in non-debug mode the scripts are cached +in the assets directory until they are deleted. +
    + +

    Compressing Javascript with GZip

    +

    +The EnableGzip property (default is true) enables the +published javascripts to be served as zipped if the browser and php server allows it. +
