js使用for循环与innerHTML获取选中tr下td值

function getParentEl (el, tagName) {if (!el) return el;do {el = el.parentNode;} while(el && el.tagName !== tagName);return el;}function temp(){//得到选中row的value值var temp=document.getElementsByName('id');for(var i=0;i<temp.length;i++){if(temp[i].checked==true){edit=temp[i].value;var tr = getParentEl(temp[i], 'TR');var tds = tr.cells;for (var j = 0; j < tds.length; j++) {var tdInner = tds[j].innerHTML;alert(tdInner);}}}}
