UI Action Condition from Script Include

[jrottman]

I'm trying to get a UI Action to appear based on a function in a script include.

My script include contents:

function myCustomShowUIButton() {

  return false;

}

The condition line of my UI action:

myCustomShowUIButton()

I would expect the UI action button to not appear because the function returns false.   However this does not appear to work.   Any ideas?

1. What is your script include name?   The way to call script include functions are

new <script>.<method name>(<parameters>);

Also while calling it from conditions, I have always see using javascript before the call. i.e.:

javascript: new <script>.<method name>(<parameters>);

2. Have you confirmed that your function is being called correctly.   I would type a gs.log statement before return to confirm that function call is correct.

Hi Jason,

A script include shouldd have a class and then a function, you can't use it without these two elements.

Here is an article concerning script include : Script Includes - ServiceNow Wiki

Why are you using script include ti hide/show button ? it could be done easily without script include. Here is another article for a sample of script : Client & Server Code in One UI Action - ServiceNow Guru

if you really want to use a script include, here is a way to achieve what are you trying to do, you have to script something like this in your script include:

1. var TestFunction = Class.create();  
2. TestFunction.prototype = Object.extendsObject(AbstractAjaxProcessor, {  
3.     testingFunction: function() {  
4. return false      
5.           }  
6.           });

Then in your ui script you have to put something like that

var ga = new GlideAjax('TestFunction');

ga.addParam('sysparm_name','testingFunction');

ga.getXML(HelloWorldParse);

function HelloWorldParse(response) {

    var answer = response.responseXML.documentElement.getAttribute("answer");

    alert(answer);

}

let me know it that works or not, this script should return the false value, you have to add in your ui action that if the answer == 'false' then

g_form.setVisible('button name', false)

Kind regards,

ZA

One note   : here is another article which shows how to interact with script include : http://wiki.servicenow.com/index.php?title=GlideAjax#gsc.tab=0

I want the button only to appear if a record appears in a different unrelated table.

I'm sure I can do it with a UI policy or a client script, I just thought the condition on a UI Action would be cleaner.   Otherwise, with a ui policy or client script, it seems like the forms shows the button, and then as soon as the java-script catches up, quickly hides the button.
