if(data_ef.length > 0) {
//////////////////////DATA OUTPUT//////////////////////
document.getElementById('get_table_ef').innerHTML = data_ef;
}
});
$.post("analysis_table/data_edgefactor.php", {AUTHID_TEST_EF: ""+auth_id+""}, function(data_ef){
var options = {
chart: {

options.series[0].data = data_ef;
chart = new Highcharts.Chart(options);
});
});

2.data_edgefactor.php代码
<?php
include '../connect.php';
$get = $_REQUEST['AUTHID_TEST_EF'];
$result_citations = mysql_query("SELECT year, citations, auth_id FROM subj_area WHERE auth_id='$get'");
$rows_citations = array();
while($r_citations = mysql_fetch_array($result_citations)) {
$row_citations[0] = $r_citations[0];

array_push($rows_citations,$row_citations);
}
print json_encode($rows_citations, JSON_NUMERIC_CHECK);

这里一切正常，图表通过 onclick 功能根据用户显示，但我需要过滤年份并根据用户选择的年份显示图表。
怎么做。请帮忙。
