Title: [SOLVED] Tree - Export tree to pdf
Post by: jega on May 30, 2018, 01:37:30 PM

Hi.

Have not the time right now to make some test, so i will ask here.

Is there any way to export a tree also ??

Have a tree with 5 nodes and a lot of childs. I need to expand a node, and all childs (can be done easy). With that tree expanded, i need to export it to at least an pdf, but xls will also be nice. Or maybe an image

Jesper

Define the functions to translate the tree data.

Code:

function translateTreeData(children, depth){
	depth = depth || 0;
	if (!children || !children.length){return []}
	var rows = [];
	$.map(children, function(item){
		var node = {text:item.text,depth:depth};
		rows.push(node);
		rows = rows.concat(translateTreeData(item.children, depth+1));
	});
	return rows;
}
function toArray(rows){
	var body = [];
	for(var i=0; i<rows.length; i++){
		var row = rows[i];
		var text = row.text;
		for(var j=0; j<row.depth; j++){
			text = '-' + text;
		}
		var item = [text];
		
		body.push(item);
	}
	return body;
}

Use the pdfmake to export pdf.

Code:

var roots = $('#tt').tree('getRoots');
var rows = translateTreeData(roots);
var body = toArray(rows);
var docDefinition = {
    content: [{
        table: {
            headerRows: 0,
            widths: ['*'],
            body: body
        }
    }]
};
pdfMake.createPdf(docDefinition).open();
