echarts折线图的数据视图样式重写
在echarts.js中，点击折线图的数据试图按钮，会以表格table的形式展示折线图中的数据，但是此时的table格式比较乱。如下图：
所以，为了展示美观需重写table的样式。echart.js的官方文档，是在配置项option中的toolbox属性中的dataview对象中重写optionToContent函数。其中class=”table-bordered table-striped”中的类为bootstrap自有的。如下图：
optionToContent:function(opt) {
var axisData = opt.xAxis[0].data;
var series = opt.series;
var table ='<table id="test" class="table-bordered table-striped" style="width:100%;text-align:center">',
var table = table + '<tbody><tr>'+ '<td>时间</td>'+ '<td>' + series[0].name + '</td>' + '<td>' + series[1].name + '</td>' + '</tr>';
for (var i = 0, l = axisData.length; i < l; i++) {
table += '<tr>' + '<td>' + axisData[i] + '</td>' + '<td>' + series[0].data[i] + '</td>' + '<td>' + series[1].data[i] + '</td>'+ '</tr>';
}
table += '</tbody>';
return table;
}
至此，数据试图的table样式已经重写。
dataTable()
首先引入dataTable的样式文件和js文件
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.15/css/jquery.dataTables.min.css">
<script type="text/javascript" language="javascript" src="js/datatable/jquery.dataTables.js"></script>
此时的解决方法是在数据试图的table 里添加名为nodeInserted 的动画：
@keyframes nodeInserted {
from { clip: rect(1px, auto, auto, auto); }
to { clip: rect(0px, auto, auto, auto); }
}
@-moz-keyframes nodeInserted {
from { clip: rect(1px, auto, auto, auto); }
to { clip: rect(0px, auto, auto, auto); }
}
@-webkit-keyframes nodeInserted {
from { clip: rect(1px, auto, auto, auto); }
to { clip: rect(0px, auto, auto, auto); }
}
@-ms-keyframes nodeInserted {
from { clip: rect(1px, auto, auto, auto); }
to { clip: rect(0px, auto, auto, auto); }
}
@-o-keyframes nodeInserted {
from { clip: rect(1px, auto, auto, auto); }
to { clip: rect(0px, auto, auto, auto); }
}
.table-data-table {
animation-duration: 0.001s;
-o-animation-duration: 0.001s;
-ms-animation-duration: 0.001s;
-moz-animation-duration: 0.001s;
-webkit-animation-duration: 0.001s;
animation-name: nodeInserted;
-o-animation-name: nodeInserted;
-ms-animation-name: nodeInserted;
-moz-animation-name: nodeInserted;
-webkit-animation-name: nodeInserted;
}
.table-data-table {
animation-duration: 0.001s;
-o-animation-duration: 0.001s;
-ms-animation-duration: 0.001s;
-moz-animation-duration: 0.001s;
-webkit-animation-duration: 0.001s;
animation-name: nodeInserted;
-o-animation-name: nodeInserted;
-ms-animation-name: nodeInserted;
-moz-animation-name: nodeInserted;
-webkit-animation-name: nodeInserted;
}
并在页面加载完后监听动画事件，以扑捉到table元素
window.onload = function() {
var insertListener = function(event){
// console.warn("Another node has been inserted! ", event);
if (event.animationName == "nodeInserted") {
$("#"+event.target.getAttribute("id")).DataTable();
console.log(event);
console.log($("#"+event.target.getAttribute("id")));
}
} ;
document.addEventListener("animationstart", insertListener, false); // standard + firefox
document.addEventListener("MSAnimationStart", insertListener, false); // IE
document.addEventListener("webkitAnimationStart", insertListener, false); // Chrome + Safari
};
整体代码如下：
