Question

长话短说。

我从后端团队获得了一个具有以下输出的hashMap。

{12 =其他服务（辅助），2 =其他服务，4 =收集，17 =获取新（适合我），19 =获取新服务（适用于我的业务）}

我是一个前端开发者，从未使用过像这样的字符串。由于＆＃39; =＆＃39;

，我无法使用jquery.split（）拆分它

在线搜索我发现了很多我的问题的答案，但是如果它确实是我问题的正确答案，那么就无法解决问题。

以下是我尝试过的内容。 $ {departmentHash}就是一个例子。我想，我的实际代码不会产生任何影响。

How to iterate HashMap using JSTL forEach loop?

(select x_item.pick_area,x_item.awkward_item,x_ploc.pick_location,
(case when  x_prod.normal_pick_area = '0' then 'Z'
when x_item.pick_area = '1' then 'A'
when x_item.pick_area = '2' then 'B'
when x_item.pick_area = '3' then 'C'
when x_item.pick_area = '4' then 'D'
when x_item.pick_area = '5' then 'E'
when x_item.pick_area = '6' then 'F'
when x_item.pick_area = '7' and substr(x_ploc.pick_location,3,2) < 22 and
                                    x_prod.awkward_item = 'YES'  then 'G'
when x_item.normal_pick_area = 'APR' and substr(x_ploc.pick_location,3,2)
   < 22 and x_item.awkward_item = 'NO'  then 'H'

when x_item.pick_area = 'APR' and substr(x_ploc.pick_location,3,2) > 21  
 and x_item.awkward_item = 'NO'  then 'I'
when x_item.pick_area = 'APR' and substr(x_ploc.pick_location,3,2) > 21   
and x_item.awkward_item = 'YES'  then 'J'

else 'Unknown' end)  area from x_item)

上述内容并未将任何内容返回到$ {department}

解析你提供的字符串因为键部分中的整数（12,2,4等）而无法工作。

如果您以字符串的形式获取hashmap数据，您可以在javascript中尝试以下内容：

var str = '{12=Other Services (Assisted), 2=Other Services, 4=Collect, 17=Get New (For Me), 19=Get New (For My Business)}';

str = str.replace('{','');
str = str.replace('}','');// these lines will remove the leading and trailing braces

var arr = str.split(','); // this will give you an array of strings with each index in the format "12=Other Services (Assisted)"

arr.forEach(function(item){
    // here you can split again with '=' and do what is required
    var s = item.split('=');
    var obj = {key: s[0], value:s[1]}; // this is up to your implementation

})

如何将以下hashMap <string，string =“”>转换为可用的JS对象？
