JS去遍历Table的所有单元格中的内容

function GetInfoFromTable(tableid) { var tableInfo = ""; var tableObj = document.getElementById(tableid); for (var i = 0; i < tableObj.rows.length; i++) { //遍历Table的所有Row for (var j = 0; j < tableObj.rows[i].cells.length; j++) { //遍历Row中的每一列 tableInfo += tableObj.rows[i].cells[j].innerText; //获取Table中单元格的内容 tableInfo += " "; } tableInfo += "\n"; } return tableInfo;}

var tabels = document.getElementsByName(tableid); alert(tabels.length); var tableObj = tabels[1];
