问题说明
在此示例中，如何将for循环中的i var值获取到guardarReserva()函数中?
guardarReserva()和GenerarGrilla()是同一myApp对象的两个方法.
guardarReserva() and generarGrilla() are both methods of the same myApp object.
var myApp = {
generarGrilla:function(){
for(var i=1; i<13; i ){
var impresionGrilla = $('#grilla').append("one");
};
},
guardarReserva:function(){
var reservaConfirmada = $('#horario').append("two");
},
正确答案
#1
您需要在两个函数之外定义i:
You would need to define i outside of both functions:
var myApp = {
i:0,
generarGrilla:function(){
for(this.i=1; this.i<13; this.i ){
var impresionGrilla = $('#grilla').append("one");
};
},
guardarReserva:function(){
var reservaConfirmada = $('#horario').append("two");
console.log(this.i);//i is now accessible
},
您还可以使用全局变量:
You can also use a global variable:
var i;
var myApp = {
generarGrilla:function(){
for(i=1; i<13; i ){
var impresionGrilla = $('#grilla').append("one");
};
},
guardarReserva:function(){
var reservaConfirmada = $('#horario').append("two");
console.log(i);//i is now accessible
},
