Angularjs：将对象传递给状态(Angularjs: passing an object params to state)

 你写： 
 
sample ar[4];
ar[4] = { 
    (1,2),
    (3,4),
    (5,6),
    (7,8) 
};
 
 数组初始化程序的语法（仅在ar的初始化期间有效）是： 
 
sample ar[4] = { 
    {1,2},
    {3,4},
    {5,6},
    {7,8} 
};
 
 
 
 C11（n1570），§6.7.9初始化 
 
 
initializer:   
    assignment-expression 
    { initializer-list } 
    { initializer-list , }
 
 
 此外， 缩写对于编写可读代码很重要。 

You have written:
 
sample ar[4];
ar[4] = { 
    (1,2),
    (3,4),
    (5,6),
    (7,8) 
};
 
The syntax of the array initializer (only valid during the initialization of ar) is:
 
sample ar[4] = { 
    {1,2},
    {3,4},
    {5,6},
    {7,8} 
};
 
 
 
C11 (n1570), § 6.7.9 Initialization
 
 
initializer:   
    assignment-expression 
    { initializer-list } 
    { initializer-list , }
 
 
Also, indentation is important to write readable code.
