根据单元格内容更改样式元素

问题描述：

我有一张桌子，像这样:

I have a table, like so:

<table>
  <tr>
    <td>one</td>
    <td>two</td>
  </tr>
  <tr>
    <td>three</td>
    <td>one</td>
  </tr>
</table>

使用Javascript，如何基于单元格的内容搜索表格并更改样式元素(例如backgroundColor)(例如，将所有带有单词"one"的单元格的背景颜色设为红色)?

Using Javascript, how can I search the table and change a style element (e.g. backgroundColor) based on the contents of a cell (e.g. make the background color of all cells with the word 'one' in them red)?

答

演示

var allTableCells = document.getElementsByTagName("td");

for(var i = 0, max = allTableCells.length; i < max; i++) {
    var node = allTableCells[i];

    //get the text from the first child node - which should be a text node
    var currentText = node.childNodes[0].nodeValue; 

    //check for 'one' and assign this table cell's background color accordingly 
    if (currentText === "one")
        node.style.backgroundColor = "red";
}
