在javascript中循环json变量

时间：2017-12-06 05:50:37

标签： javascript jquery json ajax

我有一个变量，其中我得到<%= select_tag 'recipients', recipients_options(@chosen_recipient), multiple: true, class: 'form-control chosen-it' %> 值。该值来自4个表。我想在分配值时循环每个表。以下是我的代码

json

我从表中获取值为

var dataResponse = JSON.parse(response); ，dataResponse.Table[0] ....

如何在javascript中循环它。请帮忙

我的dataResponse.Table[1]值

json

3 个答案:

答案 0 :(得分：1)

哦，我的... CREATE TABLE "PROD_INDEX" ( "PNO" NUMBER (4,0) NOT NULL ENABLE, "CATEGORY" VARCHAR(15) , "PRODUCT" VARCHAR2(10), "COUNTRY" VARCHAR2(9), "BRAND" VARCHAR(10)), "DATE" DATE, "YEAR" NUMBER(4,0), "COST" NUMBER(7,2), "SALES" NUMBER(10,2), PRIMARY KEY ("PNO") ENABLE ) / 不是dataResponse.Table。这是Array。

对于Object类似数组的对象，使用for loop。

但是，要循环Array，请使用for...in loop。

在您的情况下，可以这样做：

Object

我不会直接回答你的问题。因为很明显你没有在研究javascript中的循环方面做出任何显着的努力。

答案 1 :(得分：0)

响应是对象而不是数组。 对于迭代对象，我们使用 for-in 循环和 为了迭代数组，我们使用进行循环。 在您的情况下，您使用for-in循环。

for(var item in dataResponse){
//logic
}

}
for(count in dataResponse){
 console.log(`[[[[[[[[[[[[[${count}]]]]]]]]]]]]]]`);
 for(item of dataResponse[count]){
    console.log(item);
  }
}

您可以使用dataResponse和for-of轻松获得for-in的价值。

首先，您必须使用object name获取for-in。

其次，您可以控制表的名称。 （表，表1 ......）

for(item of dataResponse[table])将返回每个表的值。
