[英]Javascript: how to send multiple data in Ajax or Json
对不起，但是如果真的是AJAX或JSON，我会感到困惑，我不太擅长此语言。 但是我的问题是发送2个列表框值。 年和月。 今年发送到data-basic-colm-ajax.php但我不知道如何发送月份
这是我的代码：
<script type="text/javascript">
$(document).ready(function() {
//default
getAjaxData(new Date().getFullYear());
$('.dynamic_data').change(function() {
var id = $('#year').val();
var id2 = $('#month').val();
getAjaxData(id);
});
var options = {
chart: {
renderTo: 'container',
type: 'column'
},
title: {
text: 'Highcharts Chart PHP with MySQL Example',
x: -20 //center
},
subtitle: {
text: 'Subtitle',
x: -20
},
xAxis: {
categories: []
},
yAxis: {
title: {
text: 'TOTAL'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '<span style="color:{point.color}">{point.name}</span>:<b>{point.y}</b> of total<br/>'
},
plotOptions: {
series: {
borderWidth: 0,
dataLabels: {
enabled: true,
format: '{point.y}'
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 100,
floating: true,
borderWidth: 1,
shadow: true
},
series: []
};
function getAjaxData(id) {
$.getJSON("data-basic-colm-ajax.php", {id:id}, function(json) {
options.xAxis.categories = json[0]['data']; //xAxis: {categories: []}
options.series[0] = json[1];
chart = new Highcharts.Chart(options);
});
}
});
</script>
<script src="/MyCharts/highcharts/js/highcharts.js"></script>
</head>
<body>
<a class="link_header" href="/highcharts/"><< Back to index</a>
<div class="menu_top" >
Year:
<select class="dynamic_data" id="year">
<option value="2016" >2016</option>
<option value="2015">2015</option>
<option value="2011">2011</option>
</select>
Month:
<select id="month">
<option value="1" selected>Jan</option>
<option value="2">Feb</option>
<option value="3">Mar</option>
</select>
</div>
<div id="container" style="min-width: 400px; height: 400px; margin: 0 auto;"></div>
</body>
谢谢

var id = $('#year').val();
var id2 = $('#month').val();
var data = {id:id ,id2:id2};
getAjaxData(data);
});
var options = {
chart: {
renderTo: 'container',
type: 'column'
},
title: {
text: 'Highcharts Chart PHP with MySQL Example',
x: -20 //center
},
