Detailed answers to JavaScript simulated overloading and rewriting of toString method

Now I will explain in detail the javascript simulation overloading and the rewriting of the toString method. Please see the code below for details.

/***重载模拟***/ function _person(){ var args=arguments; if(typeof args[0]=="object"&&args[0]){ if(args[0].name){ this.name=args[0].name; } if(args[0].age){ this.age=args[0].age; } }else{ if(args[0]){ this.name=args[0]; } if(args[1]){ this.age=args[1]; } } }

//toString方法的重写 _person.prototype.toString=function(){ return 'name='+this.name+",age="+this.age; }

//////创建对象 var stu1=new _person("赵四","23"); stu1.toString();

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
