Javascript testing tool abut v2

based on comments from everyone, this version has made many improvements, such as optimization of annotation extraction, support for script tags, and real-time testing.

Run code
 
 
Test Example 2:
 
 
 
VaR P = function () {}// comment/* not-a-nested-Comment P ('not-a-comment '); // comment */* still-a-Comment P ('not-a-comment');/* alert ('commented-out-Code '); // still-a-Comment */P ('not-a-comment'); var Re = // \/* not-a-Comment */; // * Comment

Run code
 
 
Abut V2 adds support for scripts. For this method, the parameter is changed from a string to a hash. The Hash has three values: selector, URL, and target. Selector refers to the ID of the script tag. It is obtained through innerhtml for testing. URL refers to the path of the JS file. We get responsetext by synchronizing Ajax requests for testing. Because it is an Ajax request, it will be restricted by the same-origin policy. Therefore, I cannot release the example in V1, therefore, the selector method will be used in subsequent examples. Target refers to the element node in which the test result is put. The default value is document. body. This parameter is optional. If it is a string, it is automatically searched as the tag ID.
 
For example, if there is a script element node with ID test3 on my page, its innerhtml is as follows:
 
 
VaR person = function (name, sex) {This. name = Name; this. sex = sex; // #### log (this. name); // #### log (this. sex);} var P = new person ("Ruby", "Louvre ");
 
 
To test it, you just need to reference abut. js and run the following script on the page:
 
 
Dom. abut ({selector: ID, // script tag to be tested // URL: URL, // only the path of the same domain is limited to target: document. body // position to which the test result is added (it can be an element node or its id value )});
 
 
 
 
Run code
 
In this example, we can also see the new identifier ####, which will replace the original @@@@. @ In V1 aims to release the data in the closure or internal function to the global scope, and then test it with a series of methods $. Then, practice has proved that this is a little troublesome. Why not execute it directly in the original internal scope ?! #### It is developed for this purpose. Correspondingly, it is useless when @ is used. It is discarded and removed by me. #### The source code will be modified and then interpreted and executed, while $ will parse and execute the source code before repairing the test sample in the annotation, the execution time is totally different. $ It can be the same as EQ, same, OK, and log functions, but #### it cannot be written between >>>.
