View source for HowTo:Add a Custom Print Button to a Form

<noinclude>
{{Orientation |Designers | Intermediate | 5}}
</noinclude>This code adds a '''[Custom Print]''' button to a [[Form]], when placed in an On Load [[Form Script]]. 

In this case, the goal is to restrict a user who has access to that form to a specific template. (The standard Print operation makes all templates available. A standard [[Custom Form Action]] button, meanwhile, is present in every form. This code puts the button in a specific form, to restrict template access for users whose role causes it to be displayed.)
<noinclude>
;Set up the custom print button:
# Go to '''[[File:GearIcon.png]] > Customization > Objects > {object} > Forms > {form}
# Click '''[Form Script]'''
# Click '''[Edit]'''
# In the '''On Load Script''' area, enter the code below.
# Click '''[Save]'''

;JavaScript code:
</noinclude>
:<syntaxhighlight lang="javascript" enclose="div">
$("#print_button").remove(); 
$("#edit_button").parent().append(
"<input type='button' id='customPrint' value='Custom Print' class='lj-button fg-button ui-state-default ui-corner-all' onClick=\"javascript:lj_printRecord('default_print_layout=template&show_print_layout=no&default_print_document=jsp&default_page_orientation=landscape&default_pdf=yes&show_pdf=no&print_immediately=yes');\">"
); 
</syntaxhighlight>

;How the code works:
:; <tt>$("#print_button").remove()</tt>: Remove the standard print button
:; <tt>$("#edit_button").parent().append</tt>: Finds the location of the edit button (present in every form), gets it's parent (the toolbar), and adds the new button to it.
:; <tt>class='lj-button fg-button ui-state-default ui-corner-all'</tt>: The standard CSS style elements for platform buttons.
:; <tt><nowiki><input type='button' ...</nowiki></tt>: Define the button. (The entire string is one uninterrupted line.)
:; <tt>onClick=\"javascript:lj_printRecord(...</tt>: Specify the button's action
