I want show message on load of from

Naresh43 · ‎03-17-2022

Hello,

I have to show some field message on the form when loaded but in that it should get the value of 'program manger' and 'backup program manager' fields value I mean what it is having so, I have written on lead clent script in 'demand' table like g_form.showFieldMsg('checkbox field value','this field is to be ticked by person A and person B ',"info");

Instead of A and B it should pick the values in those 'program manager' and 'backup program manager' those are in 'program' table

Thanks in advance ...

Hmm, understood the issue, there is limitation of using getReference method i.e. you can only access data up to one dot only.

e.g. grProgram.program_manager this works but when you use grProgram.program_manager.getDisplaValue(), it is going for second dot, that is you are trying to access another record data which actually does not exist on client side.

In this case you would need to use Display BR or GlideAjax.

Please use below Display BR and client script to achieve your goal.

Business Rule :

BR script :

On load client script :

BR script for you to copy :

g_scratchpad.program_manager=current.primary_program.program_manager.getDisplayValue();
	g_scratchpad.backup_program_manager=current.primary_program.u_backup_program_manager.getDisplayValue();

Client script for you to copy:

function onLoad() {

    if (g_scratchpad.program_manager == "") {
        g_form.showFieldMsg('u_program_manager', 'This field is to be ticked by person ' + g_scratchpad.backup_program_manager);
    } else if (g_scratchpad.backup_program_manager == "") {
        g_form.showFieldMsg('u_program_manager', 'This field is to be ticked by person ' + g_scratchpad.program_manager);
    } else {
        g_form.showFieldMsg('u_program_manager', 'This field is to be ticked by person ' + g_scratchpad.program_manager +
            '\n ' + g_scratchpad.backup_program_manager);
    }

}

I haven't tested it practically but I am sure this would work, change field names properly if required.

Hi,

You can use below approach

1. Write Display BR and store program manager, backup program manager in g_scratchpad object and access the same on client script show it in error message.

2. You can use GlideAjax to get program manager, backup program manager name and show it in error message.

Let me know if you have any further queries.

If those values are already there on the form then you could directly use below,

g_form.showFieldMsg('checkbox field value','this field is to be ticked by person '+g_form.getDisplayBox("program_manager").value+'and person '+g_form.getDisplayBox("backup_program_manager").value,"info"); //change field names accordingly

Let me know if you have any further queries.

Hello Abhijit, Is not possible on load client script to show that message and it should have that values

Abhijit4 · ‎03-17-2022

Hi Naresh,

Since you have that data in reference field its stored on server not on client side there fore you would need to make server call to get that data.

If you have program field which is referring to program table then you can also use getReference method to get that data like below.

var grProgram=g_form.getReference('program_field_name',showErrorMessage);

function showErrorMessage(grProgram) { //reference is passed into callback as first arguments

g_form.showFieldMsg('checkbox field value','this field is to be ticked by person'+grProgram.program_manager_field_name+'and person'+grProgram.backup_program_manager_field_name);

}

Let me know if you have any further queries.
