我正在尝试用JS对我的表进行排序,我有大量的条目,我正在使用的当前方法是永远的,请你帮我优化它或提供更好的代码。
感谢。 :)
function sortTable(n) {
var table, rows, switching, i, x, y, shouldSwitch, dir, switchcount = 0;
table = document.getElementById("AdminT");
switching = true;
dir = "asc";
while (switching) {
switching = false;
rows = table.getElementsByTagName("TR");
for (i = 1; i < (rows.length - 1); i++) {
shouldSwitch = false;
x = rows[i].getElementsByTagName("TD")[n];
y = rows[i + 1].getElementsByTagName("TD")[n];
if (dir == "asc") {
if (x.innerHTML.toLowerCase() > y.innerHTML.toLowerCase()) {
shouldSwitch = true;
break;
}
} else if (dir == "desc") {
if (x.innerHTML.toLowerCase() < y.innerHTML.toLowerCase()) {
shouldSwitch = true;
break;
}
}
}
if (shouldSwitch) {
rows[i].parentNode.insertBefore(rows[i + 1], rows[i]);
switching = true;
switchcount++;
} else {
if (switchcount == 0 && dir == "asc") {
dir = "desc";
switching = true;
}
}
}}
