Question

我正在尝试更改那些innerHTML值与我的数组匹配的单元格背景颜色。我该怎么做？

var numbers = ["15628","15623","15656","11628"];

var table = document.querySelector("[name='main']")
.contentWindow.document.getElementById("music").rows.length;

for (i = 4; i < table -1; i++){
    if (document.querySelector("[name='main']")
.contentWindow.document.getElementById("music").rows[i].cells[1].innerHTML == numbers)
    {
    document.querySelector("[name='main']")
.contentWindow.document.getElementById("music")
.rows[i].cells[1].style.backgroundColor = "yellow";
    };

您确定此元素选择正确吗：document.querySelector（“ [name ='main']”）。contentWindow.document.getElementById（“ music”）。rows [i] .cells [1]吗？不看HTML很难分析。如果可以，则可能需要这样的解决方案：

library(dplyr)
library(tidyr)

df <- data.frame(var = c(1,2,3,0,7,8,0,0,9,8,9,0,0,0,4,7,2,4))
df <- df %>% 
  dplyr::mutate(var = ifelse(var == 0, NA, var)) %>% 
  tidyr::fill(var, .direction = c("down"))
df

如果数组包含innerHTML，则更改单元格的背景颜色
