关于数组数据存放问题

Question

varsalesOffices={};
salesOffices.clientList=[];
salesOffices.listen=function(key,fn){
if(!this.clientList[key]){
this.clientList[key]=[];
}
//我想问下这个this.clientList[key].push(fn)的表现形式是什么,
//this.clientList[key]这是个数组然后往push，会成什么结果??
//是这样的吗["squareMeter100",fucntion(){},"squareMeter80",fucntion(){},]
returnthis.clientList[key].push(fn);
}
salesOffices.listen("squareMeter100",function(price){
console.log("价格="+price);
});
salesOffices.listen("squareMeter80",function(price){
console.log("价格="+price);
});
salesOffices.trigger=function(){
varkey=Array.prototype.shift.call(arguments),fns=this.clientList[key];
if(!fns||fns.length===0){
returnfalse;
}
for(vari=0,fn;fn=fns[i++];){
fn.apply(this,arguments);
}
}
salesOffices.trigger("squareMeter100",200);
salesOffices.trigger("squareMeter80",100);

Answer 1

this.clientList是:{squareMeter100:[function(){}],squareMeter80:[function(){}]}注意数组也是对象
