}echarts在用json数据请求时未调用
3、解决办法
（1）将上述代码放在一个函数中，然后在onload中调用这个函数
（2）用jQuery方法
<script>
$(document).ready(function(){
var chart = document.getElementById('chart');
var chartData = echarts.init(chart);
chartData.setOption({
title: {
text: '异步数据加载示例'
},
tooltip: {},
legend: {
data:['销量']
},
xAxis: {
data: []
},
yAxis: {},
series: [{
name: '销量',
type: 'bar',
data: []
}]
});
$.get('../js/data.json').done(function (data) {
console.dir(data);
// 填入数据
chartData.setOption({
xAxis: {
data: data.categories
},
series: [{
name: '销量',
data: data.data
}]
});
});
function eConsole(param)
{
console.dir(param);
}
chartData.on("click",eConsole);
});
</script>
