how to add pagination in d3? i have to set pagination for each two rows,please suggest the solution. just i have added 3 rows of data but my actual data contains 50 to 100 rows

回答1:

At the simplest level you just control the visibility/display of the table rows. This example is as basic as you get , it uses two buttons to show different groups of ten in a table - no page numbering, no limiting, no styling :-) - but it does the pagination

http://jsfiddle.net/f50mggof/6/

<div id="buttons">
<button id="up">
UP
</button>
<button id="down">
DOWN
</button>
</div>
<table></table>


var dataset = [];
for (var n = 0; n < 100; n++) {
    dataset.push ([n, Math.random()*50, Math.random()*30]);
}

var rows = d3.select("table").selectAll("tr").data(dataset)
    .enter()
    .append("tr")
  ;

  var cells = rows.selectAll("td").data(function(d) { return d; })
    .enter()
    .append("td")
    .text(function(d) { return d; })
  ;

  d3.select("#buttons").datum({portion : 0});
  // the chain select here pushes the datum onto the up and down buttons also
  d3.select("#buttons").select("#up").on ("click", function(d) {
    d.portion -= 10;
    redraw (d.portion);
  });
   d3.select("#buttons").select("#down").on ("click", function(d) {
    d.portion += 10;
    redraw (d.portion);
  })

  function redraw (start) {
    d3.select("table").selectAll("tr")
        .style("display", function(d,i) {
        return i >= start && i < start + 10 ? null : "none";
      })
  }
  redraw(0);
