return JSValue::encode(jsNumber(static_cast<int32_t>(n))); } // If ToString throws, we shouldn't call ToInt32. return toStringView(globalObject, value, [&] (StringView view) { return JSValue::encode(jsNumber(parseInt(view, radixValue.toInt32(globalObject))); }); } WebKit 中的代...

std::string value = std::string(*String::Utf8Value(isolate, args[0])); // 从C++字符串转为js字符串用到了String::NewFromUtf8()函数,传入C风格字符 args.GetReturnValue().Set(String::NewFromUtf8(isolate, value.c_str())); } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. JS调用同上。

JS有7种数据类型,分别是null、undefined、boolean、number、string、object、symbol(ES6)。一般会有这么几种方法来判断数据类型: 1.typeof 就基本类型来说,除了null以外,typeof都能准确判断。(null会被typeof判断为object) typeof的问题在于:不能检测出Object下细分的类型 Array,Date,RegExp, Error。针对这些对象...
