Use JScript.net to write. net Applications

Javascript is a magic language, flexible, easy to learn, and advanced in concept. But now it seems to have been pinned on the browser. In fact, this is the biggest misunderstanding of javascript. MS. the net platform provides full-featured JScript support. However, this JScript complies with the ECMA standard. Like M $'s attitude towards other international standards, JScript adds many other capabilities, so people accidentally bound them to windows. But it doesn't matter. Our topic this time is to write a. net program. It doesn't matter if it is bound. Who makes me a "drop-down to MS"? In fact, I basically don't want to go through money.

After. net sdkis installed, jsc.exe is installed. Before official use, we need to set up an integrated compilation environment. bigtall uses UltraEdit, so a new command is created in the menu "Advanced/tool configuration: the menu item name is "JScript.net compilation". Command Behavior: C: WindowsMicrosoft.NETFrameworkv2.0.50727jsc.exe/fast-"% f"; working directory: % p; remember to set "output" to "output to list box" and save it.

 

With the environment, we can start to write some test code. First, create a test. js, standard javascript code:

 

 

Var arr = ["a", "B"]; Var obj = {name: "test", value: 3.0 }; Print (arr [0]); Print (arr [1]); Print (obj. name ); Print (obj. value );

Run the following menu command to compile successfully. A test.exe file is displayed in the current directory. It runs normally!

 

 

If you want to compile a complete program, I am afraid one file is not enough. So let's test the compilation of multiple files and create a mod. js file with the following content:

 

Function hello () { This. name = "haha "; } Function haha () { Print ("call haha "); }

Then we modify test. js as follows:

 

Var arr = ["a", "B"]; Var obj = {name: "test", value: 3.0 }; Print (arr [0]); Print (arr [1]); Print (obj. name ); Print (obj. value ); Import mod; Var t = new hello (); Print (t. name );

However, compilation is learned. We need to compile it manually. In cmd, enter jsc/fast-mod. js test.jsto compile a mod.exe file and run it! However, if we compile and run the jsc/fast-test. js mod.js command, the test.exe cannot be run because we cannot find things in mod. js. This is an important part of attention.

 

 

Because JScript has made a lot of extensions, we need to test whether the extension commands and non-extensions can cooperate with each other, because we need to compile. and. net programs.. net SDK. It is necessary to use extensions. Create a new file pkg. js with the following content:

Import System; Package France. Paris { Public class Landmark { Static var Tower: String = "Eiffel Tower "; Function p () { System. Console. WriteLine ({t: "hello from writeline"}. t ); } } };

Modify test. js as follows:

Var arr = ["a", "B"]; Var obj = {name: "test", value: 3.0 }; Print (arr [0]); Print (arr [1]); Print (obj. name ); Print (obj. value ); Var t = new hello (); Print (t. name ); Haha (); Print (France. Paris. Landmark. Tower ); Import France. Paris; New Landmark (). p ();
