Javascript 将HTML链接添加到Google图表表

Javascript 将HTML链接添加到Google图表表,javascript,Javascript,我正在尝试向Google图表表列添加一个HTML链接。我为列和表设置了setHTML:true,但它只是显示HTML代码,而不是解释它。有人能给我指出正确的方向吗 谢谢 <!-- You are free to copy and use this sample in accordance with the terms of the Apache license (http://www.apache.org/licenses/LICENSE-2.0.html) --> <!DO

谷歌可视化API示例
load('visualization','1',{packages:['table']});
函数drawVisualization(){
//创建并填充数据表。
var data=google.visualization.arrayToDataTable([
['Name','已登录'],
[“第2项”],
]);
setColumnProperty(0,{allowtml:true});
//创建并绘制可视化。
可视化=新的google.visualization.Table(document.getElementById('Table');
绘制(数据,{allowtml:true});
}
setOnLoadCallback(drawVisualization);
​

allowHTML属性区分大小写。它必须是{allowtml:true}。

您应该使用


如果将值替换为HTML,则排序将无法正常工作。

可视化=新建google.visualization.Table…
可视化.draw(数据,{allowtml:true})
之间,添加一个新类,以格式化列:

示例:在这里,我们使用第三列中给出的URL链接包含网站名称的第一列,然后在第三列中链接URL字符串本身。列的索引不是data.table中的实际索引,而是相对于
.format(data,[,])
的,后者是在声明变量以格式化列之后指定的

//包含网站标题的超链接列
var format_name=新的google.visualization.PatternFormat(
'');
//超链接URL列
var format_url=new google.visualization.PatternFormat(
'');
//应用格式化程序
//提取format_name变量的前三列(或0和2)
格式_name.format(数据[0,1,2]);
//提取format_url变量的第三列
format_url.format(数据,[2]);
//使用DataView为data.table创建只读视图
var view=newgoogle.visualization.DataView(数据);
//对data.table源使用视图而不是原始数据
draw.draw(视图,{allowtml:true});

您能详细说明一下吗?
// hyperlink column containing website title
var format_name = new google.visualization.PatternFormat(
'<a href="{2}">{0}</a>');

// hyperlink URL column
var format_url = new google.visualization.PatternFormat(
'<a href="{0}">{0}</a>');

// apply formatters
// extract first three columns (or 0 and 2) for format_name variable
format_name.format(data, [0,1,2]);

// extract the third column for format_url variable
format_url.format(data, [2]);

// Use DataView to create read-only view for data.table
var view = new google.visualization.DataView(data);

// Use view instead of original data for data.table source
visualization.draw.draw(view, {allowHTML: true});
