Need a Catalogue Client Script To Make a Mandatory Single Text field To Read Only based on Condition (True or False on a Check Box selection)

[Sonam_Tiwari]

Try something like

var checkBoxField = g_form.getValue('check_box_field');

if (checkBoxField == 'true') {
    g_form.setMandatory('single_line_text', false);
    g_form.setReadOnly('single_line_text', true);
} else {
    g_form.setMandatory('single_line_text', true);
    g_form.setReadOnly('single_line_text', false);
}​
