1. Use Firebug to debug JavaScript
3. The number of errors in the status bar
4. An error that shows the current page
Firebug is a very powerful tool that can help you find errors in your code and resolve them.
Here we use Firebug to handle Javascript code.
First we need to load the page and open the Firebug.
Sometimes you need to reload the page.
Break point debugging can terminate the execution of code, and you can see if the error is within the specified code range by specifying the code range. This is useful for error debugging.
If you click the Step over button, Firebug updates all variables until you terminate break point execution in the right window.
You can write an expression that stops code execution when the condition is true.
You can use a quick search to find keywords in your code.
