我在jQuery对象中有一个方法，如下所示：
formatPhone: function(phone){
return phone.substring(0,3) + "." + phone.substring(3,6) + "." + phone.substring(6,10);
}
在THAT SAME对象中，我这样称呼它：
"<h4>" + this.formatPhone(item.MainPhone) + "</h4>"
我得到“TypeError：'undefined'不是函数（评估'this.formatPhone（item.MainPhone）'）
我控制台记录了物品对象，而MainPhone肯定有值。
是不是我说的不正确???
感谢任何帮助。

答案 0 :(得分：1)
您应该将其称为：yourObjectname.formatPhone()，而不是this
例如，请参阅以下代码：
var yourObjectname = {
formatPhone: function(phone){
return phone;
},
anotherFunction: function(){
alert(this.formatPhone('555'));
}
}
yourObjectname.anotherFunction();
// or
alert(yourObjectname.formatPhone('555'));
您可以看到this只能在特定对象内使用，但在外面您应该拨打yourObjectname
