can we hide custom button using onchange client script ?

[String]

Hi Team ,

We created a custom button in the form .

My requirement is when user changes the state field ,we are making few fields  blank and want to hide/disable the custom button .

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
g_form.setValue('date', "");
g_form.setValue('last_com', "");

we are making few fields blank ,but how to make custom button hide/disable ?

Please guide

You would do this in the conditions of the UI Action.

Hello @String 

1) Create a UI Policy --> Set Condition as field (check_box) is true

2) In the Script tab set Run scripts true

3) In the if condition write        

                  $$('#action_name')[0].hide();     //This will hide the top button

                  $$('#action_name')[1].hide();     //This will hide the bottom button as well

4) In the else condition write        

                  $$('#action_name')[0].show();     //This will show the top button

                  $$('#action_name')[1].show();     //This will show the bottom button as well

Plz Mark my Solution as Accept and Give me thumbs up, if you find it helpful.

Hello @String 

Go to UI policy, add your If Condition with state changes , in it add it

3) In the if condition write        

                  $$('#action_name')[0].hide();     //This will hide the top button

                  $$('#action_name')[1].show();     //This will hide the bottom button as well

4) In the else condition write        

                  $$('#action_name')[0].show();     //This will show the top button

                  $$('#action_name')[1].show();     //This will show the bottom button as well
