javascript - Is there any good way to encapsulate parts like this? ~

Question

Now I feel like it’s not good to write everywhere. What if I want to change my name that day? Should I replace them one by one? ~

Answer 1

Or you can write an intermediary function to handle the addition, deletion, modification and query of related variables? Let’s see if others have a better way

var o = {
    data : {},
    add : function(key,val){
       if(!key) return false;
       var data = this.data;
       data[key] = data[key] || {};
       data[key] = val;
    },
    del : function(key){
        if(!key) this.data = {};
        delete this.data[key];
    },
    changeVal : function(obj){
        if( Object.prototype.toString.call(obj) != '[object Object]' )
        obj = {};
        
        var data = this.data;
        for( var key in obj){
            if(data[key]){
                data[key] = obj;
            }
        }
    }
    //.......
    //写了个简单的，如果要求更复杂可以自己去拓展
};

It’s a bit difficult to get the value. If you want to assign the value, you can create a new function for the assignment. If you want to modify the value, just call the function directly,
