js code for sorting table data in html_javascript skills

By the way, pay attention to the innerText and innerHTML

Copy code The code is as follows:

function sortCells(event ) {
var obj = event.target;
var count = 0; count records the number of clicks, in ascending or descending order according to odd and even
if(!obj.getAttribute("clickCount")){
obj.setAttribute("clickCount", 0);
} else {
count = parseInt(obj.getAttribute("clickCount"));
count ;
obj.setAttribute("clickCount ", count);
}
var table = event.target.parentNode.parentNode;
if(table.nodeName.localeCompare("THEAD") == 0){
if(table. parentNode.nodeName.localeCompare("TABLE") == 0){
table = table.parentNode;
} else {
return;
}
} else if(table.nodeName. localeCompare("TBODY") == 0){
if(table.parentNode.nodeName.localeCompare("TABLE") == 0){
table = table.parentNode;
} else {
return;
}
} else if(table.nodeName.localeCompare("TABLE") == 0){
} else {
return;
}
var colNum;
for(x = 0; x if(event.target.innerText.localeCompare(table.rows(0).cells[x] .innerText) == 0){
colNum = x;
break;
}
}
var column = table.rows(1).cells.length;
var row = table.rows.length;
var Ar = new Array(row - 1);
for (x = 0; x Ar[x] = new Array (column);
}
for (x = 1; x for (y = 0; y Ar[x - 1 ][y] = table.rows(x).cells(y).innerHTML;
}
}
　　　　///This can perform localized sorting of strings
/* if((count %2) == 0){
Ar.sort(function(a, b) {
return b[colNum].localeCompare(a[colNum])
});
} else {
Ar.sort(function(a, b) {
return a[colNum].localeCompare(b[colNum])
});
} */
var temp;
for (x = 0; x for (y = 1; y temp = Ar[y - 1];
if((count % 2) == 0){
if (parseInt(Ar[y - 1][colNum]) >= parseInt(Ar[y][colNum])) {
Ar[ y - 1] = Ar[y];
Ar[y] = temp;
}
} else {
if (parseInt(Ar[y - 1][colNum]) Ar[y - 1] = Ar[y];
Ar[y] = temp;
}
}
}
}
for (x = 1; x for (y = 0; y table.rows(x).cells(y ).innerHTML = Ar[x - 1][y];
}
}
count ;
}
