WebAssembly.LinkError.prototype.constructor

指明创建该实体的构造函数.

WebAssembly.LinkError.prototype.message

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

WebAssembly.LinkError.prototype.name

Error name. Inherited from Error.

WebAssembly.LinkError.prototype.fileName

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

WebAssembly.LinkError.prototype.lineNumber

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

WebAssembly.LinkError.prototype.columnNumber

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

WebAssembly.LinkError.prototype.stack

Stack trace. Inherited from Error.

Methods

The LinkError constructor contains no methods of its own, however, it does inherit some methods through the prototype chain.

WebAssembly.LinkError.prototype.toSource()

返回可以执行并得到与该错误对象相同的源代码.

WebAssembly.LinkError.prototype.toString()

返回一个可以说明该 Error 对象的文字. 继承自  Error.

Examples

下列代码片段创建了一个新的 LinkError 实例, 并将其打印到控制台:

try {
  throw new WebAssembly.LinkError('Hello', 'someFile', 10);
} catch (e) {
  console.log(e instanceof LinkError); // true
  console.log(e.message);                 // "Hello"
  console.log(e.name);                    // "LinkError"
  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
}
