js使用for循環(huán)與innerHTML獲取選中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(){
    //得到選中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);
    }
    }
    }
    }
