js循环数组各种方法
eg1：eg2：
for (var i in array) {
alert(array[i]);
}
alert(array[i]);
}
for(var i in this.$GLOBAL_DETAIL.album_photo_ids){if(this.$GLOBAL_DETAIL.album_photo_ids[i] == "3487675024077108") alert(this.$GLOBAL_DETAIL.album_photo_ids[i]);}
eg3：
eg4：
// And now x is [10,20,30,40]
eg5：
eg6：
eg7：
// logs: 'one','three'
and for the reverse order,an even more efficient loop
var items = ['one','three'],i=items.length;
while(i--){
console.log(items[i]);
}
// logs: 'three','one'
or the classical for loop
var items = ['one','three']
for(var i=0,l=items.length; i < l ; i++){
console.log(items[i]);
}
// logs: 'one','three'
eg8：
' + myStringArray[i]); // i is the index/key,not the item
}
js循环map，获取所有的key和value
eg1：菜单页面
guangfaPage : "loadPage.htm?url=/collect/menu.page",// 进入广发信息收集页面
pinganPage : "loadPage.htm?url=/collect/menu.page",// 进入平安信息收集页面
nuonuoPage : "loadPage.htm?url=/collect/menu.page",// 进入诺诺信息收集页面
youbangPage : "loadPage.htm?url=/collect/menu.page",// 进入友邦信息收集页面
inputMobileNo : "loadPage.htm?url=/collect/inputMobileNo.page",// 进入输入手机号页面
readIdCard : "loadPage.htm?url=/collect/readIdCard.page",// 进入读取身份证页面
member : "loadPage.htm?url=/collect/member.page",// 进入输入会员卡号页面
bankCard : "loadPage.htm?url=/collect/bankCard.page",// 进入插入银行卡页面
url : "loadPage.htm?url=/collect/url.page" // 进入跳转url页面
},for(var key in this.pageUrl){
alert(key+" : "+this.pageUrl[key]);
}
eg2：
for (var prop in obj) {
if (obj.hasOwnProperty(prop)) {
// or if (Object.prototype.hasOwnProperty.call(obj,prop)) for safety...
alert("prop: " + prop + " value: " + obj[prop])
}
}
if (obj.hasOwnProperty(prop)) {
// or if (Object.prototype.hasOwnProperty.call(obj,prop)) for safety...
alert("prop: " + prop + " value: " + obj[prop])
}
}
