Hi Vijay_Katoch

 

You said I can do that in validate form button. What is a validate form button, how can I do this? I cannot find anything from official document.

 

Thanks very much


I meant to say you can write a script to validate if the required checkboxes are checked or not.

For that, you can give a button and write a script on that for checking whether the required field is checked or not.

or Can write the script on the checkbox to check whether any two check box selected in that question.

@fulongt37334138  what kind of form is it?

 

1. PDF Then you need to write a script on exit to validate if two are selected or not

2. Same logic as 1 in case of adaptive form on value commit and validate

        What do you mean check 2 items? Is it like you want to check 2 checkboxes on checking one checkbox?

         

        If this is the case then you can do like below:

         

        In java script: eg. checkbox on/off values are 0/1

        form1.CheckBox1::click - (JavaScript, client)
        if(this.rawValue == 1){
        CheckBox2.rawValue =1;
        }else{
        CheckBox2.rawValue =0;
        }

         

         

        or You can map the 2 checkboxes with the same node in schema if you are using one.

            You need to check the value of those items to make sure that 2 are selected. You can do that in validate form button.
