It is sometimes encountered in Apex that you need to get the values in the option list field. For example, there may be multiple provinces under a provincial field, such as Heilongjiang, Beijing, Henan and so on. How do you show all the values?

When Xiao Meow first came into contact with this situation, it was like this, ↓.

ManProvinceOption = new List (); ManProvinceOption.add (new SelectOption ('all', 'all'); ManProvinceOption.add (new SelectOption ('Shandong', 'Shandong'); ManProvinceOption.add (new SelectOption ('Heilongjiang', 'Heilongjiang'); ManProvinceOption.add (new SelectOption ('Jilin', 'Jilin'); ManProvinceOption.add (new SelectOption ('Jiangsu', 'Jiangsu')) ManProvinceOption.add (new SelectOption ('Shenzhen', 'Shenzhen'); ManProvinceOption.add (new SelectOption ('Shanghai', 'Shanghai')); ManProvinceOption.add (new SelectOption ('Zhejiang', 'Zhejiang')); ManProvinceOption.add (new SelectOption ('Fujian', 'Fujian'); ManProvinceOption.add (new SelectOption ('Guangdong', 'Guangdong')); ManProvinceOption.add ('Guangxi', 'Guangxi')) ManProvinceOption.add (new SelectOption ('Dalian', 'Dalian'); ManProvinceOption.add ('Anhui', 'Anhui'); ManProvinceOption.add (new SelectOption ('Gansu', 'Gansu')); ManProvinceOption.add (new SelectOption ('Shenyang', 'Shenyang'); ManProvinceOption.add (new SelectOption ('Jiangxi', 'Jiangxi'); ManProvinceOption.add ('Shanxi', 'Shanxi')) ManProvinceOption.add (new SelectOption ('Xinjiang', 'Xinjiang'); ManProvinceOption.add ('Hunan', 'Hunan'); ManProvinceOption.add (new SelectOption ('Tianjin', 'Tianjin')); ManProvinceOption.add (new SelectOption ('Henan', 'Henan'); ManProvinceOption.add ('SP headquarters','SP headquarters')) ManProvinceOption.add (new SelectOption ('Yunnan', 'Yunnan'); ManProvinceOption.add (new SelectOption ('Hubei', 'Hubei')); ManProvinceOption.add (new SelectOption ('Beijing', 'Beijing')); ManProvinceOption.add (new SelectOption ('Sichuan', 'Sichuan'); ManProvinceOption.add ('Inner Mongolia', 'Inner Mongolia')) ManProvinceOption.add (new SelectOption ('Shaanxi', 'Shaanxi'); ManProvinceOption.add (new SelectOption ('Hebei', 'Hebei'); ManProvinceOption.add ('GIR headquarters', 'GIR headquarters'); ManProvinceOption.add (new SelectOption ('Guizhou', 'Guizhou'); ManProvinceOption.add ('Chongqing', 'Chongqing')) ManProvinceOption.add (new SelectOption ('Qinghai', 'Qinghai')

Writing data in this way is dead data. If there are some big changes in the future, how troublesome will it be?

Meow used to learn Java, when we need a drop-down list is queried from the database table, and then display.

Xiao Meow inquired about it from the Internet, and there is indeed this kind of operation in salesforce. Here is the code for my friends.

It uses Schema.DescribeFieldResult to get the description of the option list field getDescribe ().

Example:

ManProvinceOption= new List (); Schema.DescribeFieldResult fieldResult2 = OPDPlan__c.ProvinceOption__c.getDescribe (); List ple2 = fieldResult2.getPicklistValues (); for (Schema.PicklistEntry f: ple2) {ManProvinceOption.add (new SelectOption (f.getLabel (), f.getLabel ();}

Format:

/ / the variable name of the variable that holds the data is 0 = new List (); / / gets the value of the Schema.DescribeFieldResult variable name of the object's option list field 1 = object. Option list field .getDescribe (); List variable name 2 = variable name 1.getPicklistValues (); for (Schema.PicklistEntry f: variable name 2) {variable name 0.add (new SelectOption (f.getLabel (), f.getLabel () } about how to get the values in the list of options in Apex in Salesforce, so much for sharing here.
