有没有办法自定义Google图表以防止他们显示此"红色"消息?例如,默默地画什么?
谷歌图表/可视化提供了一系列事件,方法和工具,用于自定义错误处理,错误消息等.
例如,请参阅https://developers.google.com/chart/interactive/docs/reference#errordisplay或https://developers.google.com/chart/interactive/docs/examples#querywrapper
根据您的要求,最简单的方法是简单地附加错误处理程序,并在该处理程序中,通过删除错误google.visualization.errors
.
像这样 :
function errorHandler(errorMessage) {
//curisosity, check out the error in the console
console.log(errorMessage);
//simply remove the error, the user never see it
google.visualization.errors.removeError(errorMessage.id);
}
function drawChart(json) {
var data = new google.visualization.DataTable(json); //here, JSON is buggy
var options = {
title: 'test'
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
//attach the error handler here, before draw()
google.visualization.events.addListener(chart, 'error', errorHandler);
chart.draw(data, options);
}

中提琴!尝试将errorHandler
and 添加google.visualization.events.addListener(chart, 'error', errorHandler);
到现有代码中,并查看差异(这就是您所需要的).
