Dynamic or Conditional display of Jenkins job's parameters - jenkins

Question

I am trying to use following jenkins job to generate Active Choices user selectable params for a job.
my ask is to show/hide textbox when heartbeat_consumer checkbox is selected/unselected. I would also like to store the value of user input in heartbeat_consumer_parms, which can be accessed thru env.heartbeat_consumer_parms. I plan to use this value in downstream jobs.
pipeline {
agent any
stages {
stage('Parameters'){
steps {
script {
properties([
parameters([
text(
defaultValue: '''''',
name: 'application_servers',
description: 'Please provide semicolon delimited (;) application server list ',
),
[$class: 'CascadeChoiceParameter',
choiceType: 'PT_CHECKBOX',
description: 'Select Services',
name: 'application_services_list',
referencedParameters: 'application_servers',
script:
[$class: 'GroovyScript',
fallbackScript: [
classpath: [],
sandbox: false,
script: "return['']"
],
script: [
classpath: [],
sandbox: false,
script: '''
if (application_servers.length() > 0){
return["heartbeat_consumer", "surgeon_cloud_login", "system_configuration"]
}
'''
]
]
]
])
])
if (application_services_list.contains('heartbeat_consumer')){
text(
defaultValue: '''''',
name: 'heartbeat_consumer_parms',
description: 'Please provide heartbeatconsumer job parms ',
)
}
}
}
}
}
}
with current implmentation I am not seeing that textbox heartbeat_consumer_parms is being displayed at all.

Pipeline script for your scenario:
properties([
parameters([
[$class: 'ChoiceParameter',
choiceType: 'PT_CHECKBOX',
description: 'Select the Application Service from the Dropdown List',
filterLength: 1,
filterable: false,
name: 'application_services_list',
script: [
$class: 'GroovyScript',
fallbackScript: [
classpath: [],
sandbox: false,
script:
"return['Could not get the services list']"
],
script: [
classpath: [],
sandbox: false,
script:
"return['heartbeat_consumer', 'surgeon_cloud_login', 'system_configuration']"
]
]
],
[$class: 'DynamicReferenceParameter',
choiceType: 'ET_FORMATTED_HTML',
description: 'SAdd params',
name: 'heartbeat_consumer_parms',
omitValueField: 'true',
referencedParameters: 'application_services_list',
script:
[$class: 'GroovyScript',
script: 'return["Could not get Information"]',
script: [
script: '''
if (application_services_list.equals("heartbeat_consumer")){
inputBox="<input type ='text' id = 'myText' name='value' >"
return inputBox
}
'''
]
]
]
])
])
pipeline {
environment {
vari = ""
}
agent any
stages {
stage ("Example") {
steps {
script{
echo "${params.application_services_list}"
echo '\n'
echo "${params.heartbeat_consumer_parms}"
}
}
}
}
}
Please find the screenshot of the output:

this worked for me,
pipeline {
agent any
stages {
stage('Parameters'){
steps {
script {
properties([
parameters([
text(
defaultValue: '''''',
name: 'application_servers',
description: 'Please provide semicolon delimited (;) application server list ',
),
[$class: 'CascadeChoiceParameter',
choiceType: 'PT_CHECKBOX',
description: 'Select Services',
name: 'application_services_list',
referencedParameters: 'application_servers',
script:
[$class: 'GroovyScript',
fallbackScript: [
classpath: [],
sandbox: false,
script: "return['']"
],
script: [
classpath: [],
sandbox: false,
script: '''
if (application_servers.length() > 0){
return["heartbeat_consumer", "surgeon_cloud_login", "system_configuration"]
}
'''
]
]
],
[$class: 'DynamicReferenceParameter',
choiceType: 'ET_FORMATTED_HTML',
description: 'enter job params',
name: 'hb_job_params',
referencedParameters: 'application_services_list',
script:
[$class: 'GroovyScript',
fallbackScript: [
classpath: [],
sandbox: false,
script: "return['']"
],
script: [
classpath: [],
sandbox: false,
script: '''
if (application_services_list.contains('heartbeat_consumer')){
return """<textarea name=\"value\" rows=\"5\" class=\"setting-input \"></textarea>"""
}
'''
]
],
omitValueField: true
],
])
])
}
}
}
}
}
I used, DynamicReferenceParameter for using HTML generated textarea however accessing entered textarea values was tricky. after a bit of researching I found that,
The trick for formatting a text input box is to format the HTML in a way that reflects the HTML Jenkins uses to display parameters in a job submission form. The easiest way to do this is to review the HTML Jenkins uses to display an existing String parameter.
