javascript - 通过tr id从同一个表中读取td值

Question

我正在尝试根据 tr id 读取表的值，但无法理解如何执行此操作。

    // Id of the tr in question for example.row_17 
    var d =c["id"]; 
    console.log(d); 

    // Here I can read all the td values, but I only want
    // the ones inside the tr id = "row_17" 

    var cols =document.getElementById('report_table').getElementsByTagName('td'), 

     colslen = cols.length, i = -1; > while(++i < colslen)
    {  console.log(cols[i].innerHTML); 

}

既然你用 jQuery 标记了它，你可以通过这样做来做到这一点:

var id = c["id"];

// Select only the row with id specified in 'id' and loop through all 'td's' of that row.
$("#" + id).find("td").each(function()
{
    // Log the html content of each 'td'.
    console.log($(this).html());
});
