JavaScript中创建字典对象(dictionary)的实例 对于JavaScript来说,其自身的Array对象仅仅是个数组,无法提供通过关键字来获取保存的数据,jQuery源码中提供了一种非常好的方式来解决这个问题,先看一下源码: 复制代码 代码如下: function createCache() { var keys = []; function cache(key, value) { // Use (key ...
当JS调用OC方法时,在OC方法中可以用此方法获取到执行的函数+(JSValue*)currentCallee;//获取当前执行的JS函数中的this指向的对象+(JSValue*)currentThis;//获取当前执行函数的参数列表,当JS调用OC方法时,在OC方法中可以用此方法获取到执行的函数的参数列表+(NSArray*...

JavaScript array/dictionary Object on a [ScriptableMember] property or parameter on a [ScriptableMember] method. You must wrap the JavaScript array/dictionary with a call to the create methods and related helper methods to convert it to a managed type. JavaScript array/dictionary ScriptObject. This...
Output data from Code steps Code steps return a singleoutputvariable, which is an object or array of objects that will be the result of this step. You can explicitly return early. If the output is an array of objects, subsequent steps will run multiple times, once for each object in the...
RapydScript will also properly detect native JavaScript classes (String, Array, Date, etc.). Unfortunately, RapydScript has no way of detecting classes from third-party libraries. In those cases, you could use the new keyword every time you create an object from such class. Alternatively, you...
NSDictionary Object NSArray Array NSDate Date Block Function id Object Class Object 下面这些方法可以将JSValue值转换为Objective-C中的数据类型: //将JSValue转换为OC对象 - (id)toObject; //将JSValue转换成特定OC类的对象 - (id)toObjectOfClass:(Class)expectedClass; //将JSValue转换成布尔值 - (...
Types that are List<T>, Dictionary<string,V>, or t[] (array of t) are supported. The specific type of the array or generic parameter is specified by using a mini-language that is supported by the create methods. See the method descriptions later in this topic for syntax inform...
