WebAssembly.CompileError object indicates an error during WebAssembly decoding or validation.

构造函数

WebAssembly.CompileError()

创建新的 WebAssembly.CompileError 对象。

实例特性

WebAssembly.CompileError.prototype.message

Error message. Although ECMA-262 specifies that URIError should provide its own message property, in SpiderMonkey , it inherits Error.prototype.message .

WebAssembly.CompileError.prototype.name

Error name. Inherited from Error .

WebAssembly.CompileError.prototype.fileName

Path to file that raised this error. Inherited from Error .

WebAssembly.CompileError.prototype.lineNumber

Line number in file that raised this error. Inherited from Error .

WebAssembly.CompileError.prototype.columnNumber

Column number in line that raised this error. Inherited from Error .

WebAssembly.CompileError.prototype.stack

Stack trace. Inherited from Error .

实例方法

WebAssembly.CompileError.prototype.toSource()

Returns code that could eval to the same error. Inherited from Error .

WebAssembly.CompileError.prototype.toString()

Returns a string representing the specified Error object.. Inherited from Error .

范例

Creating a new CompileError instance

The following snippet creates a new CompileError instance, and logs its details to the console:

try {
  throw new WebAssembly.CompileError('Hello', 'someFile', 10);
} catch (e) {
  console.log(e instanceof CompileError); // true
  console.log(e.message);                 // "Hello"
  console.log(e.name);                    // "CompileError"
  console.log(e.fileName);                // "someFile"
  console.log(e.lineNumber);              // 10
  console.log(e.columnNumber);            // 0
  console.log(e.stack);                   // returns the location where the code was run
}
