reportJSException is a method used in uni-app to report JavaScript exceptions. This method is typically used to capture and log JavaScript errors that occur during the execution of a uni-app application. By reporting these exceptions, developers can identify and fix issues more effectively.

Usage

To use reportJSException, you can call it in your App.vue or other components where you want to catch and report JavaScript errors.

Here’s an example of how you might use it:

// App.vue
export default {
  onLaunch() {
    // Capture global JavaScript errors
    window.onerror = function(message, source, lineno, colno, error) {
      uni.reportJSException({
        message: message,
        source: source,
        lineno: lineno,
        colno: colno,
        stack: error ? error.stack : ''
      });
      return true; // Prevent the default error handler from firing
    };

    // Capture unhandled promise rejections
    window.onunhandledrejection = function(event) {
      uni.reportJSException({
        message: event.reason ? event.reason.message : 'Unhandled promise rejection',
        stack: event.reason ? event.reason.stack : ''
      });
    };
  }
};

Parameters

The reportJSException method accepts an object with the following properties:

  • message: The error message.
  • source: The URL of the script where the error occurred.
  • lineno: The line number where the error occurred.
  • colno: The column number where the error occurred.
  • stack: The stack trace of the error.

Example

uni.reportJSException({
  message: 'Undefined variable',
  source: 'https://example.com/app.js',
  lineno: 42,
  colno: 13,
  stack: 'Error: Undefined variable\n at https://example.com/app.js:42:13'
});
