Export to PDF dynamic page orientation

obworley

I got this to work a couple of hours ago and have since broken it again. I just can't figure out what I'm doing wrong. I'm trying to dynamically change the page orientation of a pdf document based on the number of columns. I'm new to DataTables and am still trying to figure out a lot of it.

Button Print strips the br's from fields that have multiple lines and replaces with \n

var buttonPrint = { exportOptions: { format: { body: function ( data, column, row, node ) { // Strip br from rows so they will print return column ? data.replace(/<br\s*[\/]?>/gi, '\n') : data; } } } };

$.extend( true, {}, buttonPrint, { extend: 'pdfHtml5', exportOptions: {columns: ':visible', stripNewlines:false}, pageSize: 'LETTER', footer: true, customize: function(doc) { doc.styles.title.fontSize = 8; doc.defaultStyle.fontSize = 6; doc.styles.tableHeader.fontSize = 6; doc.styles.tableFooter.fontSize = 6; }, orientation: function (){ var api = this.api(); var count = api.columns().header().length; if(count> 8){ orientation = 'landscape'; }else{ orientation = 'portrait'; } } } )

Sorry - didn't realize using the Code insert would look like that.

var buttonPrint = {
exportOptions: {
format: {
body: function ( data, column, row, node ) {
// Strip br from rows so they will print
return column ?
data.replace(/<br\s*[\/]?>/gi, '\n') :
data;
}
}
}
};

$.extend( true, {}, buttonPrint, {
extend: 'pdfHtml5',
exportOptions: {columns: ':visible', stripNewlines:false},
pageSize: 'LETTER',
footer: true,
customize: function(doc) {
doc.styles.title.fontSize = 8;
doc.defaultStyle.fontSize = 6;
doc.styles.tableHeader.fontSize = 6;
doc.styles.tableFooter.fontSize = 6;
},
orientation: function (){
var api = this.api();
var count = api.columns().header().length;
if(count> 8){
orientation = 'landscape';
}else{
orientation = 'portrait';
}
}
} )
