Javascript 增加key或value至Object中

042 月 2015 by Bryce No Comments

直接建立一個object的方法：

var obj = {
    key1: value1,
    key2: value2
};

var obj = {

key1: value1,

key2: value2

};

或是

var employees = []; 
employees.push({id:100,name:'Yashwant',age:30});
employees.push({id:200,name:'Mahesh',age:35});

var employees = [];

employees.push({id:100,name:'Yashwant',age:30});

employees.push({id:200,name:'Mahesh',age:35});

直接指定進object中的方法：

obj.key3 = "value3";

1	obj.key3 = "value3";

或

obj["key3"] = "value3";

1	obj["key3"] = "value3";

另外有一種進階方式，使用函數來呼叫

var getProperty = function (propertyName) {
    return obj[propertyName];
};

getProperty("key1");
getProperty("key2");
getProperty("key3");

var getProperty = function (propertyName) {

return obj[propertyName];

};

getProperty("key1");

getProperty("key2");

getProperty("key3");
