Author Topic: Add JavaScript Attribute to Custom Data Text Field (Read 2871 times)

I'd like to add an onBlur attribute to a CiviCRM custom text field. Is there a way I can set an attribute in one of the template files? Or maybe write some code in a core Form.php file?

I wondered if an option could be to grab the field's HTML from the $customPost array and perform a str_replace to change "<input" to "<input onBlur='....'"? I'm not sure the right place where I would need to do something like this or the right way to access it from CiviCRM's array.

Any advice would be appreciated.

you should check: CRM/Core/BAO/CustomField.php, function addQuickFormElement

QuickForm can take a 'attributes' argument which it copies into the input element (search for attributes in that function)

Just so I understand, the suggestion is to build a custom input field on the page using addQuickFormElement, and pass to it what attributes it should have?

This is for a CiviCRM field that is already standard on the main CiviContribute page. Does it make sense to rebuild a field that already exists in core or will I run into other problems?

That function actually creates the custom fields which have been "assigned" to a given form. Since you have a custom field on that form, I think the suggestion is to modify the function to add your onblur attribute for a specific instance of a custom field (probably using a conditional on the $elementName or $label value).
