dw javascript no prompt

When programming in the JavaScript language, a code editor is often used to assist in writing code. However, when editing code, sometimes no prompts appear, which makes writing code very difficult. So, how to solve the problem when there is no prompt when using JavaScript?

First of all, we need to understand how the code editor prompt appears. Generally speaking, when we enter code in the editor, the code will be automatically parsed, and then the editor will automatically provide us with possible options and suggestions for the next step. This process is called "intelligent prompting". However, in some cases, this process does not happen and we do not get any prompts.

Next, let’s introduce several common situations without prompts and corresponding solutions:

1. The editor does not correctly identify the file type

When we open a file, the editor needs to determine the type of file so that it can provide us with the correct prompts. If the file type is not recognized correctly, the editor may lose its smart prompt functionality. For example, when using the Visual Studio Code editor, if the file extension is not .js or .jsx, the editor may not be able to parse the code correctly.

Solution: Change the file extension to .js or .jsx, or manually tell the editor the file type.

2. Lack of necessary plug-ins or extensions

Some editors may need to install plug-ins or extensions to provide smart prompts. If the editor we install does not have the corresponding plug-ins or extensions installed, we may not be able to get the correct prompts.

Solution: Search for the plug-in or extension we need in the editor's plug-in store or extension store, and install it. After the installation is complete, just reopen the editor.

3. The code contains grammatical errors or formatting problems

If our code contains grammatical errors or formatting problems, the editor may not be able to parse the code correctly, thus Unable to provide smart tips.

Solution: Check whether there are grammatical errors or formatting problems in the code, and if so, modify them. We can use code review tools or code style checking tools to help us find these problems.

4. Incorrect editor settings

The editor settings may also prevent us from getting smart tips. For example, in some editors, you may need to manually turn on the smart prompt function.

Solution: Open the editor settings, look for settings related to smart prompts, and ensure that the settings have been turned on correctly.

In short, no hints are a common problem in JavaScript programming. However, as long as we check and adjust the relevant settings, the problem can be solved. Once we found the solution and made the adjustments, we were able to happily write our JavaScript code.
