Javascript 如何在HTML表格和d3条形图中创建下拉列表
如何创建一个下拉菜单，让用户为这个HTML表格和d3条形图选择一个时间间隔？我需要在这里创建的inveral时间是：现在，24小时、48小时、72小时、1周和1个月。我对动态表创建和d3图表非常陌生。非常感谢你的宝贵帮助。我的代码如下：Javascript 如何在HTML表格和d3条形图中创建下拉列表,javascript,html,css,d3.js,Javascript,Html,Css,D3.js,如何创建一个下拉菜单，让用户为这个HTML表格和d3条形图选择一个时间间隔？我需要在这里创建的inveral时间是：现在，24小时、48小时、72小时、1周和1个月。我对动态表创建和d3图表非常陌生。非常感谢你的宝贵帮助。我的代码如下： <!DOCTYPE html> <html> <head> <title>Demo</title> <style> .hide {
