javascript - call ajax function onload and on button click -


i want show report base on election date. when call function showreport() on form load working, it's not working when call function on button click.

report members image

<script> function showreport(){    var = $('#from').val();    var = $('#to').val();    var str = $('#str').val();  if(from == '' && == '')  {     var = '$from';     var = '$to';  } $.ajax({     url: "crm_data_report.php?type="+str+"&from="+from+"&to="+to,     method: "post",     success: function(data) {     console.log(data);     var date = [];     var value = [];     for(var in data)     {     date.push(data[i].date);     value.push(data[i].value);     }     var color = chart.helpers.color;     var chartdata = {     labels: date,     datasets :     [     {     label: 'members',     backgroundcolor: color(window.chartcolors.red).alpha(0.5).rgbstring(),     bordercolor: window.chartcolors.red,     borderwidth: 1,     data: value     }     ]     };     var ctx = $("#mycanvas");     var bargraph = new chart(ctx, {     type: 'bar',     data: chartdata     });     },     error: function(data) {     console.log(data);     }     }); }

the code called function on load , on button click.

<script> $(document).ready(function(){    showreport(); }); $('#filter').click(function(){     showreport(); }); </script>

replace code block this:

$(function(){     $('#filter').click(function(){         showreport();     });     })

its common issue binding click event when button not available dom yet , have bind when dom tree ready.
