<h1>See on csv faili töötlemise demo</h1>

Sisesta esimese tulba otsiv väärtus:
<input type="text" id="filter" onkeypress="return filtreeri2(event)">
<button type="button" onclick="filtreeri()">filtreeri!</button> 

Tulemus ilmub siia:
<p>

<div id="result"></div>

<p>
Andmed võetakse csv failist <a href="data.csv">data.csv</a>.
<p>
Programm kasutab <a href="https://github.com/okfn/csv.js">csv.js</a> teeki csv faili parsimiseks ja siis siin
lehe lähtekoodis olev meie oma <tt>processdata</tt> programm, mida saad ise edasi ehitada.
<script>

// processdata takes data rows, builds html string and shows it in the div above
var sisu;

function filtreeri() {  
  sisu=document.getElementById("filter").value;
  //alert(sisu);
  drawdata();
}

function filtreeri2(e) {  
  sisu=document.getElementById("filter").value;
  //alert(sisu);

  if (e.keyCode == 13) drawdata();
}

function processdata(rows) {
  
  var rownr, colnr, row, el;
  var result;
  
  // build the result html string
  result="<table>";
  // loop over all rows
  for(rownr=0; rownr<rows.length; rownr++) {    
    row=rows[rownr];
	if (!sisu || row[0]==sisu) {
		result=result+"\n<tr>";	
		// loop over columns in one row
		for(colnr=0; colnr<row.length; colnr++) {
		  el=row[colnr];		  
		  if (rownr==0) {
			result=result+"<th><b>"+el+"</b></th>"; 
		  } else {
			result=result+"<td>"+el+"</td>";
		  }				  
		}
		result=result+"</tr>";
    }		 
  }
  // put the result html string into the div on the page
  console.log(result);
  document.getElementById("result").innerHTML=result;  
}

// take raw csv data, parse it into rows and then call processdata with the result
// we use the CSV library from https://github.com/okfn/csv.js 

function drawdata() {
	CSV.fetch({
		// several options to give input, by default we use the file data.csv
		//url: 'data.csv'
		
		// alternatively put raw data here like this:
		data: //"esimene;teine\na;1\nb;2"
	"aaa,bb,cc,dd\n"+
	"a1,as2,d$$d,11\n"+
	"443,22,2,2ö$$öö\n"
		
		// also an alternative
		//file: an HTML 5 file object

		// optional options about structure of the CSV file
		// following the CSV Dialect Description Format 
		// https://frictionlessdata.io/specs/csv-dialect/
		/*
		dialect: {
		  ...
		}
		*/
	  }
	).done(function(dataset) {  
	  // console.log(dataset); // optional debugging    
	  var allrows;
	  // put the dataset field list and dataset records into one array of all rows
	  allrows=dataset.records;
	  allrows.unshift(dataset.fields);  
	  // call our program for building html
	  processdata(allrows);
	});
