DW calls Javascript method

Dreamweaver is a powerful web design tool that integrates a Javascript code editor. When writing web pages, we usually use some Javascript functions to complete some interactive operations, such as form validation, page switching, interactive effects, etc. How to let Dreamweaver call Javascript method? Let’s discuss this issue below.

<button onclick="greeting()">点击我</button>

3. Add an onclick event to the button element so that the function can be called when the button is clicked. The function is called inline, that is, the click event is added directly to the HTML element.

3. Test run

2. Click the test button.

If everything goes well, you should see a prompt box popping up containing "Hello World!"
