[英]Sorting HTML table not working properly
我有一个HTML表:
<table id="myTable2" border="1">
<tr>
<th onclick="sortTable(0)"> Code </th>
<th onclick="sortTable(1)"> Name </th>
<th onclick="sortTable(2)"> Total Input </th>
<th onclick="sortTable(3)"> Total Output </th>
<th onclick="sortTable(4)"> Total Retour </th>
<th onclick="sortTable(5)"> Stock Left </th>
<th onclick="sortTable(6)"> Safety Stock </th>
<th onclick="sortTable(7)"> Stock Status </th>
</tr>
</table>
我正在尝试通过使用以下脚本向其添加排序功能:
<script>
function sortTable(n) {
var table, rows, switching, i, x, y, shouldSwitch, dir, switchcount = 0;
table = document.getElementById("myTable2");
switching = true;
//Set the sorting direction to ascending:
dir = "asc";
/*Make a loop that will continue until
no switching has been done:*/
while (switching) {
//start by saying: no switching is done:
switching = false;
rows = table.getElementsByTagName("TR");
/*Loop through all table rows (except the
first, which contains table headers):*/
for (i = 1; i < (rows.length - 1); i++) {
//start by saying there should be no switching:
shouldSwitch = false;
/*Get the two elements you want to compare,
one from current row and one from the next:*/
x = rows[i].getElementsByTagName("TD")[n];
y = rows[i + 1].getElementsByTagName("TD")[n];
/*check if the two rows should switch place,
based on the direction, asc or desc:*/
if (dir == "asc") {
if (x.innerHTML.toLowerCase() > y.innerHTML.toLowerCase()) {
//if so, mark as a switch and break the loop:
shouldSwitch= true;
break;
}
} else if (dir == "desc") {
if (x.innerHTML.toLowerCase() < y.innerHTML.toLowerCase()) {
//if so, mark as a switch and break the loop:
shouldSwitch= true;
break;
}
}
}
if (shouldSwitch) {
/*If a switch has been marked, make the switch
and mark that a switch has been done:*/
rows[i].parentNode.insertBefore(rows[i + 1], rows[i]);
switching = true;
//Each time a switch is done, increase this count by 1:
switchcount ++;
} else {
/*If no switching has been done AND the direction is "asc",
set the direction to "desc" and run the while loop again.*/
if (switchcount == 0 && dir == "asc") {
dir = "desc";
switching = true;
}
}
}
}
</script>
对于前两列(“代码”和“名称”),排序功能可以很好地工作,包括升序和降序选项。 但是在表的其余部分,该功能无法正常工作。 几行向上或向下移动,但不是按排序顺序。 有人可以告诉我如何解决吗? 谢谢。
将功能更改为:
<script>
function sortTable(n,isNum) {
var table, rows, switching, i, x, y, shouldSwitch, dir, switchcount = 0;
table = document.getElementById("myTable2");
switching = true;
//Set the sorting direction to ascending:
dir = "asc";
/*Make a loop that will continue until
no switching has been done:*/
while (switching) {
//start by saying: no switching is done:
switching = false;
rows = table.getElementsByTagName("TR");
/*Loop through all table rows (except the
first, which contains table headers):*/
for (i = 1; i < (rows.length - 1); i++) {
//start by saying there should be no switching:
shouldSwitch = false;
/*Get the two elements you want to compare,
one from current row and one from the next:*/
x = rows[i].getElementsByTagName("TD")[n].innerHTML;
y = rows[i + 1].getElementsByTagName("TD")[n].innerHTML;
if (isNum) {
/* Convert to float */
x = parseFloat(x);
y = parseFloat(y);
}
else
{
/* change to lowercase */
x = x.toLowerCase();
y = y.toLowerCase();
}
/*check if the two rows should switch place,
based on the direction, asc or desc:*/
shouldSwitch = ((dir =="asc") && (x>y)) || ((dir =="desc" && (x<y))
if (shouldSwitch) {
/*If a switch has been marked, make the switch
and mark that a switch has been done:*/
rows[i].parentNode.insertBefore(rows[i + 1], rows[i]);
switching = true;
//Each time a switch is done, increase this count by 1:
switchcount ++;
} else {
/*If no switching has been done AND the direction is "asc",
set the direction to "desc" and run the while loop again.*/
if (switchcount == 0 && dir == "asc") {
dir = "desc";
switching = true;
}
}
}
}
</script>
将您的HTML更改为:
<table id="myTable2" border="1">
<tr>
<th onclick="sortTable(0, 0)"> Code </th>
<th onclick="sortTable(1, 0)"> Name </th>
<th onclick="sortTable(2, 1)"> Total Input </th>
<th onclick="sortTable(3, 1)"> Total Output </th>
<th onclick="sortTable(4, 1)"> Total Retour </th>
<th onclick="sortTable(5, 1)"> Stock Left </th>
<th onclick="sortTable(6, 1)"> Safety Stock </th>
<th onclick="sortTable(7, 1)"> Stock Status </th>
</tr>
</table>
