JavaScriptCore框架 _JSContext (1)

  1. 给JSContext对象添加属性
  2. 调用JSContext方法
# 给JSContext对象添加属性
JSContext *context = [[JSContext alloc] init];
    JSValue *value = [context evaluateScript:@"1+1"];
    NSLog(@"%@", value);
    
    [context evaluateScript:@"var name = 'zhangsan'"];
    NSLog(@"%@", context[@"name"]);   
# 添加一个log方法
    context[@"log"] = ^(){
        //处理不定参数(调用时传的参数)
        NSArray *array = [JSContext currentArguments];
        
        for (id item in array) {
            
            NSLog(@"%@", item);
        }
    };

    # 调用方法
    [context evaluateScript:@"log(1,2,3)"];```

    例子:

JSContext *context = [[JSContext alloc] init];

context[@"dic"] = @{@"name":@"lala", @"age":@"11"};

context[@"log"] = ^(){
    //处理不定参数
    NSArray *array = [JSContext currentArguments];
    
    for (id item in array) {
        
        NSLog(@"%@", item);
    }
};

[context evaluateScript:@"log(dic)"];
[context evaluateScript:@"log(dic.name)"];
