first step:
Remove eclipse's JS verification:
Set windows->preference->Java Script->Validator->Errors/Warnings->
Remove the hook in front of Enable Javascript Sematic validation;
Step 2:
Right-click the project -> properties -> Builders Remove the hook in front of JavaScript Validator
If there is no JavaScript Validator in Builders. Then go to the .project file to modify the following content:
Find the project directory and delete the following parts in the .project file in the project directory:
<buildCommand>
<name></name>
<arguments></arguments>
</buildCommand>
and <nature></nature>
Note that modifying the .project file may require restarting eclipse, or closing the project in eclipse and then opening the project again.
Step 3:
Copy the js file to a certain place, and then delete the error from eclipse directly. The error disappeared, and then the one just now
Copy a js file.
If the above is not correct after doing it, open the Problems view in Eclipse, select the relevant errors, and solve them according to the prompts.
