我正在尝试使用jqplot http://www.jqplot.com/tests/cursor-highlighter.php。我已经成功地将它安装在我的框架中。但是我需要在图表中的数据点上推送一个点击事件。

这是我目前的代码，

<script class="code" type="text/javascript">
    $(document).ready(function () {
        var line1 = [['23-May-08', 578.55], ['20-Jun-08', 566.5], ['25-Jul-08', 480.88], ['22-Aug-08', 509.84],
      ['26-Sep-08', 454.13], ['24-Oct-08', 379.75], ['21-Nov-08', 303], ['26-Dec-08', 308.56],
      ['23-Jan-09', 299.14], ['20-Feb-09', 346.51], ['20-Mar-09', 325.99], ['24-Apr-09', 386.15]];
        var plot1 = $.jqplot('chart1', [line1], {
            title: 'Πωλήσεις από 23-May-08 μέχρι 24-Apr-09',
            axes: {
                xaxis: {
                    renderer: $.jqplot.DateAxisRenderer,
                    tickOptions: {
                        formatString: '%b&nbsp;%#d'
                    }
                },
                yaxis: {
                    tickOptions: {
                        formatString: '€%.2f'
                    }
                }
            },
            highlighter: {
                show: true,
                sizeAdjust: 9.5
            },
            cursor: {
                show: false
            }
        });
        $.jqplot.eventListenerHooks.push(['jqplotClick', myClickHandler]);
    });
    function myClickHandler(ev, gridpos, datapos, neighbor, plot) {alert(1);}
</script>

这是我尝试添加点击事件

$.jqplot.eventListenerHooks.push(['jqplotClick', myClickHandler]); and
 function myClickHandler(ev, gridpos, datapos, neighbor, plot) {alert(1);}

lol我找到了:)。答案是:

<script class="code" type="text/javascript">
    $(document).ready(function () {
        var line1 = [['23-May-08', 578.55], ['20-Jun-08', 566.5], ['25-Jul-08', 480.88], ['22-Aug-08', 509.84],
      ['26-Sep-08', 454.13], ['24-Oct-08', 379.75], ['21-Nov-08', 303], ['26-Dec-08', 308.56],
      ['23-Jan-09', 299.14], ['20-Feb-09', 346.51], ['20-Mar-09', 325.99], ['24-Apr-09', 386.15]];
        var plot1 = $.jqplot('chart1', [line1], {
            title: 'Πωλήσεις από 23-May-08 μέχρι 24-Apr-09',
            axes: {
                xaxis: {
                    renderer: $.jqplot.DateAxisRenderer,
                    tickOptions: {
                        formatString: '%b&nbsp;%#d'
                    }
                },
                yaxis: {
                    tickOptions: {
                        formatString: '€%.2f'
                    }
                }
            },
            highlighter: {
                show: true,
                sizeAdjust: 9.5
            },
            cursor: {
                show: false
            }
        });

        /* CLICK CODE START*/
        $('#chart1').bind('jqplotDataClick',
            function (ev, seriesIndex, pointIndex, data) {                
                alert(1);
            }
        );
        /* CLICK CODE END*/
    });
</script>
