Abstract

Various technologies and techniques are disclosed for creating interruptible client-side scripts. Input is received from a developer to write original code for a web application in at least one client-side script. A code injection process is programmatically performed to modify the original code to make one or more parts of an execution of the code interruptible in the client-side script. The code injection process parses a code segment of a client-side script to retrieve a next code segment. If the next code segment has at least one conditional semantic construct, then code is injected in the form of one or more script functions that will transition execution flow from the original code segment into the one or more script functions that are operable to interrupt execution of the client-side script upon user request. The modified code resulting from the code injection process is saved for the web application.

Claims

1. A method for creating an interruptible client-side script comprising the steps of:

receiving input from a developer to write original code for a web application in at least one client-side script;

during creation of the web application, programmatically performing a code injection process to modify the original code to make one or more parts of an execution of the original code interruptible in the client-side script, wherein the code injection process modifies one or more original code sections that contain conditional semantic constructs, wherein the original code sections are modified to call a transition process that will allow a user operating the web application from a web browser to cancel an execution of the conditional semantic construct; and

saving the modified code resulting from the code injection process for the web application.

2. The method of claim 1, wherein the at least one client-side script is written in JavaScript.

3. The method of claim 1, wherein the at least one client-side script is written in VBScript.

4. The method of claim 1, wherein code injection process comprises:

parsing a plurality of code segments to retrieve a particular code segment; and

if the particular code segment has at least one conditional semantic construct, then injecting one or more script functions that will transition execution flow from the original code to the one or more script functions.

5. The method of claim 4, wherein the parsing and injecting stages are repeated for a plurality of conditional semantic constructs.

6. The method of claim 1, wherein the code injection process begins automatically upon saving of the web application.

7. The method of claim 1, wherein the code injection process begins when the developer selects an option to begin the code injection process.

8. The method of claim 1, wherein the code injection process re-factors the original code into more manageable chunks.

9. The method of claim 1, wherein the modified code is sent to the client browser of a user accessing the web application.

10. The method of claim 9, wherein the user is an end user accessing the web application in a live mode.

11. The method of claim 9, wherein the user is the developer accessing the web application in a debug mode.

12. A computer storage medium having computer-executable instructions for causing a computer to perform the steps recited in claim 1.

13. A computer storage medium having computer-executable instructions for causing a computer to perform steps comprising:

receive input from a developer to write original code for a web application using one or more client-side scripts;

during creation of the web application, cause a code injection process to begin, wherein the code injection process is operable to begin automatically upon saving of the web application;

during creation of the web application, perform the code injection process to make certain parts of an execution of the original code interruptible, wherein the code injection process modifies one or more original code sections that contain conditional semantic constructs, wherein the original code sections are modified to call a transition process that will allow a user operating the web application from a web browser to cancel an execution of the conditional semantic construct; and

during creation of the web application, save the modified code that results from the code injection process.

14. The computer storage medium of claim 13, wherein the code injection process is operable to parse a plurality of code segments to retrieve a particular code segment, and if the particular code segment has at least one conditional semantic construct, then injecting one or more script functions that will transition execution flow from the code to the one or more script functions.

15. A method for performing a code injection process to make a client-side script interruptible comprising the steps of:

receive input from a developer to write original code for a web application using one or more client-side script;

during creation of the web application, parsing an original code segment of a particular client-side script to retrieve a next original code segment;

if the next original code segment has at least one conditional semantic construct, then, during creation of the web application, modifying one or more original code sections that contain the at least one conditional semantic construct, wherein the code sections are modified to call a transition process that will allow a user operating the web application from a web browser to cancel an execution of the at least one conditional semantic construct;

repeating the parsing and injecting code stages for any additional code segments that contain at least one conditional semantic construct; and

during creation of the web application, save the modified original code.

16. A readable computer storage medium having computer-executable instructions for causing a computer to perform the steps recited in claim 15.
