下面这段代码如何改成自动从大到小排版

图片说明这是打开页面的默认排序，但是我想要的是，一打开页面不通过点击就默认按里面的数值大小来排序

现在这段代码是需要点击从能实现排序的，请问一下如何改成自动从大到小排序

你已经实现了点击排序就已经完成了啊
点击是一个事件，页面加载也是一个事件
你再body标签上加个onload就好了

字符串不能进行大小的比较的，先将字符串进行转义再进行比较

<!DOCTYPE HTML>

HelloWorld table { margin: 0 auto; border: 1px solid black; border-collapse: collapse; } td { border: 1px solid black; } **function sort()**{ var table = document.getElementById ('table'); var tbody = table.tBodies[0]; var rows = tbody.rows; var cells = rows[0].cells; for ( var j = 0; j < cells.length; j++) { cells[j].onclick = function () { var asc = this.asc = !!this.asc ? -this.asc : -1; var array = []; array.index = this.cellIndex; for ( var i = 1; i < rows.length; i++) { array.push (rows[i]); } array.sort (function (a, b) { var n1 = a.cells[array.index].firstChild.nodeValue; var n2 = b.cells[array.index].firstChild.nodeValue; if (n1 > n2) { return asc; } else if (n1 < n2) { return -asc; } else { return 0; } }); for ( var i = 0; i < array.length; i++) { tbody.appendChild (array[i]); } } } }

编号	姓名
98	李勇
94	王博
705	刘海
1025	陈锋

function sort(){ sort 实现。。。}

.....

csdn评论转义代码，等下

<script>
function sort(){  sort 代码。。。}
</script>
<body onload="sort()">
....
</body>

用sort()函数实现
