Syntax

JavaScript
sErrorName = object.name

 

Property values

Type: DOMString

A DOM Error Code.

Remarks

The name property indicates the type of error that occurred. Because DOMException objects and DOMError objects both return DOM error codes, it is possible to create general routines to handle errors consistently.

Examples

The following example shows one way to create a shared error handler using JavaScript:

JavaScript
Copy 

var fileReader = new FileReader();

fileReader.onerror = function() {
   handleError(this.error); 
};

try {
   fileReader.readAsArrayBuffer(blob);
} 
   catch(exception) {
      handleError(exception);
   }

// handleError can be used for either 
// DOMError or DOMException errors

function handleError(error) {
   if (error.name == "NotFoundError")
      handleNotFoundError();
   if (error.name == "InvalidStateError")
      handleInvalidStateError();
}
