我是新的web開發尤其是jquery等。在我的代碼中,morris圖表被認爲是來自ajax請求的數據。下面的代碼片段
HTML
Morris圖表undefined使用jquery ajax php
<div id = "node" class = "something">//some divs here</div>
<div id = "myModal role = "dialog">//some divs here again
<div class = "modal-body"><div id = "my_chart"></div></div></div>
的Javascript
<script type="text/javascript">
$(document).ready(function(){
var chart_data = '';
var div_id = '';
$(".something").click(function(){
div_id = jQuery(this).attr("id");
$.ajax({
type : 'POST',
url : 'test1',
data : { "node_num" : div_id},
success: function(data){
chart_data = data;
console.log(chart_data);
$('#myModal').modal();
},
error: function(data){
alert("Something went wrong, please refresh");
}
});
});
$("#myModal").on('shown.bs.modal', function(){
$('#my_chart').empty();
var chart = Morris.Area({
element: 'my_chart',
data: chart_data,
xkey: 'time',
ykeys:['power'],
labels:['Power(Watts)'],
pointSize: 2,
hideHover: 'auto',
resize: true,
lineColors: ['#1abc9c'],
fillOpacity: 0.75,
parseTime: false
});
});
$(".something").hover(function(){
$(this).css('cursor','pointer');
})
});
</script>
PHP
public function test1()
{
$node_num = $this->input->post('node_num');
$chart = '';
$chart_data = '';
$query = $this->Nodes->get_chartdata($node_num);
foreach($query->result() as $row)
{
$time = substr($row->n_date, -8);
$power = ($row->voltage)*($row->current);
$chart .= "{ power: ".$power.", time: '".$time."' }, ";
}
$chart_data = '['.$chart.']';
echo $chart_data;
}
PHP OUTPUT
[{功率:21.837696,時間:'10:59:41' },{功率:2.07552,時間:'11:00:23' },{功率: 14.09736,時間:'11:00:42'},{power:10.149408,time:'11:03:52'},{power:20.195136,time:'13:45:01'},]
據推測,morris圖表會顯示圖表like this(我用php輸出替換了數據:chart_data)。相反,我得到this。我遵循其他方法,但它仍然是一樣的。任何幫助我如何解決這個問題?提前感謝你!
現在我明白了補充
dataType:'json',
。非常感謝!我終於得到了我需要的東西。 –
