我在这里做错了什么?我的数组是空的。
var infoarray = [{\"address\":\"07288 Albertha Station\",\"city\":\"Littelside\",\"created_at\":\"2011-05-25T19:24:51Z\",\"id\":1,\"name\":\"Mr. emmitt emmerich\",\"state\":\"Missouri\",\"updated_at\":\"2011-05-25T19:24:51Z\",\"zip\":\"75475-9938\"},{MORE INFO}]
// Populates myarray from infoarray ruby object
var myarray = new Array();
$(document).ready(function(){
$.each(infoarray,function(key,value){
myarray.push(value[\'city\'])
});
});
console.log(myarray);
解决方法
javascript区分大小写,因此InfoArray和infoarray是不同的变量。
这行得通吗?:
var hotelinfo = [{\"address\":\"07288 Albertha Station\",\"city\":\"Littelside\",\"created_at\":\"2011-05-25T19:24:51Z\",\"id\":1,\"name\":\"Mr. Emmitt Emmerich\",\"state\":\"Missouri\",\"updated_at\":\"2011-05-25T19:24:51Z\",\"zip\":\"75475-9938\"},{MORE INFO}]
// Populates myarray from infoarray ruby object
var myarray = new Array();
$(document).ready(function(){
$.each(hotelinfo,function(key,value){
myarray.push(value[\'city\'])
});
});
console.log(myarray);
,我不认为
InfoArray = var hotelinfo = [{\"address\":\"07288 Albertha Station\",{MORE INFO}]
是有效的JavaScript。您必须将其拆分:
var hotelinfo;
InfoArray = hotelinfo = [{\"address\":\"07288 Albertha Station\",{MORE INFO}]
,JavaScript区分大小写,请使用
$.each(InfoArray,value){
即InforArray与inforarray不同。还行
InfoArray = var hotelinfo =
应该
InfoArray = hotelinfo =
,在表达式中间声明变量是无效的。 var关键字必须在一行的开头。在一行中声明多个变量是完全有效的,但是var关键字必须是该行的第一个。
