在特定环境下数据类型转换时(如把对象转换字符串),valueOf()方法的优先级要比toString()方法的优先级高。 function Point(x,y){ this.x=x; this.y=y; } Point.prototype.valueOf=function(){ return "("+this.x+","+this.y+")" } Point.prototype.toString=function(){ return "[object Point]" }...
这能简单看出,是可以使用toString转换进制了。那这时候我们就来用HTMl、JAVA实验一下。 2 HTMl实验toString 效果图 完整代码 <!DOCTYPE html>南方者 - 掘金console.log("getHEX(64, 8):", getHEX(64, 8));console.log("getHEX(100, 3):", getHEX(100, 3));console.log("getHEX(206, 4):", get...
varobj={};obj.valueOf=function(){return10;}obj.toString=function(){return"return value";}varresult=obj+1;//var result = obj.valueOf() + 1;alert(result);alert(obj);//alert(obj.toString()); (2)返回值类型的差别: toString一定将所有内容转为字符串 ...
