Enhancements to Export Form functionality

[kartik-v]

• Entirely eliminate rendering of the export form via GridView class
• Render export form dynamically via javascript and append to body
• This will allow the grid export to be embedded within another form (and not cause any nested html form error).

If I want to manipulate the data generated by the export function, what event can I use as a trigger? I previously had an "on submit" event for the export form with class "kv-export-form", since it was already rendered, but now it is not working anymore since the form is not rendered with the gridview.

@kartik-v I checked the modified code and in this part:

$('<form/>', {'action': self.action, 'target': target, 'method': 'post', css: {'display': 'none'}})
                .append(getInput('export_filetype', type), getInput('export_filename', self.filename))
                .append(getInput('export_encoding', self.encoding), getInput('export_bom', self.bom ? 1 : 0))
                .append(getInput('export_content', content), getInput('module_id', self.module), $csrf)
                .append(getInput('export_mime', mime), getInput('export_hash', hashData), getInput('hash_export_config', 
                 hashConfig))
                .append(getInput('export_config', JSON.stringify(config)))
                .appendTo('body')
                .submit()
                .remove();

Wouldn't adding a class kv-export-form attribute for the <form> tag solve this?
