我正在尝试根据tr id读取表的值,但无法解决如何执行此操作。
// 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);
}

由于您使用jQuery标记它,您可以通过执行以下操作来执行此操作:
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());
});

万一你想要一个只有JavaScript的解决方案(没有jQuery):
var id = c["id"];
var tds = document.querySelectorAll('#' + id + ' td');
for(var i = 0; i < tds.length; i++) {
console.log(tds[i].innerHTML);
}
