Question

知道为什么以下代码不起作用？我的目标是遍历每一行并根据值将样式应用于单元格。出于某种原因，我的代码只更新了第一行。

工作似乎很适合这份工作。

function blah（）{

        var table = document.getElementById("tbl-appointment-requests");

        for (var i = 0, row; row = table.rows[i]; i++) {

            for (var j = 0, col; col = row.cells[j]; j++) {

                if (col.id === "alternativeAptTime") {
                    if (col.id.innerHTML === "0") {
                        col.className = "glyphicon glyphicon-remove";
                        col.innerHTML = null;
                    } else {
                        col.className = "glyphicon glyphicon-ok";
                        col.innerHTML = null;
                    }
                }

} }
