With the continuous development of web application development, Javascript has become an indispensable part of web development. Eclipse is a widely used IDE and there are many Javascript developers developing Javascript applications in Eclipse. However, in Eclipse 3.7, many developers encountered a problem: Eclipse did not give any error prompts when errors occurred in Javascript code. In this article, we’ll take a closer look at this problem and how to fix it.
Problem Description
When an error occurs in Javascript code, you will usually see useful information about the error type and error location in the browser's console. However, when we develop Javascript applications in Eclipse 3.7, Eclipse does not give any error prompts even if there are obvious errors in the code. This will cause us to encounter great difficulties when debugging Javascript code.
The reason for this problem is that Eclipse does not display Javascript errors by default. To solve this problem, we need to take some measures.
Solution
The solution to this problem is very simple, we only need to set Eclipse to display Javascript errors. The following are the specific steps:
Step 1: Open Eclipse preferences
In Eclipse, click the "Window" menu, and then select "Preferences".
Step 2: Find the Javascript option
In the "Preferences" dialog box, expand the "General" option. Then select "Editors"->"Text Editors"->"Annotations".
Step 3: Enable Javascript Errors
In the "Annotations" tab, find the "Javascript" errors. Then check "Text as" and "Highlight" and make sure the "Vertical ruler" option is also checked.
Now, when you edit Javascript code in Eclipse, if an error occurs in the code, you will see an error message. At this point, you can quickly find the location of the error and fix it. This can greatly speed up your Javascript development.
Conclusion
In this article, we introduced ways to handle Javascript errors in Eclipse 3.7. If you develop web applications in Eclipse, this issue may affect your productivity. However, you can easily solve this problem using the above-mentioned methods. After completing these steps, Eclipse will always show you Javascript errors and you can fix them faster.
