}外面加个判断吧。取到的trCount是10,每个tr后面还有一个textnode,tbody的chialdnodes一共5个tr加5个空文本节点。所以后面就报错了。
trCount = obj.parentNode.rows.length; // 获得行数(tr)
indexTR = obj.rowIndex //tr索引值
lineCount = obj.cells.length//一行有几个td
for (i = 1; i < trCount; i++) {
for (j = 0; j < lineCount; j++) {
with (obj.parentNode.rows[i].cells[j]) {
style.backgroundColor = "";
style.cursor = "pointer";
}
}
