我当前的代码有一个复选框求和函数，它从数据库中获取值。
我也在尝试将另一个Javascript代码应用到我的表中，这样我就可以对行中的数据进行排序。
例如，在对行进行排序后，在顶部显示所有5个ACER资产。我想勾选前5个显示的ACER资产的复选框并总结它们。
这是我目前的代码：
<?php
include('connect1.php');
$retrieve = $db->prepare("SELECT count(*) FROM Asset");
$retrieve->execute();
$fetchrow = $retrieve->fetch(PDO::FETCH_NUM);
$calculated=$fetchrow[0];
?>
<script type="text/javascript">
function UpdateCost() {
var sum = 0;
var gn, elem;
for (i=0; i<<?php echo $calculated ?>; i++) {
gn = 'sum_m_'+i;
elem = document.getElementById(gn);
if (elem.checked == true) { sum += Number(elem.value); }
}
document.getElementById('totalcost' ).value = sum.toFixed(0);
}
window.onload=UpdateCost
</script>
<link rel="stylesheet" href="style.css" />
Total Cost : <input type="text" name="sen" id="totalcost" value="" />
<table cellpadding="0" cellspacing="0" border="0" id="table" class="sortable">
<thead>
<tr>
<th><h3>Asset ID</h3></th>
<th><h3>Vendor</h3></th>
<th><h3>Hardware </h3></th>
<th><h3>Cost</h3></th>
<th><h3>Date Of Purchase</h3></th>
<th><h3>Select Values</h3></th>
</tr>
</thead>
<tbody>
<?php
// include('connect1.php'); you already included this file
$result = $db->prepare("SELECT * FROM Asset");
$result->bindParam(':userid', $res);
$result->execute();
for($i=0; $row = $result->fetch(); $i++){
?>
<tr>
<td><?php echo $row['Asset_ID']; ?></td>
<td><?php echo $row['Vendor_Name']; ?></td>
<td><?php echo $row['Hardware_ID']; ?></td>
<td><?php echo $row['Asset_Cost']; ?></td>
<td><?php echo $row['DateOfPurchase']; ?></td>
<th><h3><INPUT TYPE="checkbox" NAME="items[]" value="<?php echo $row['Asset_Cost'] ?>" id="sum_m_<?php echo $i ?>" onclick="UpdateCost()"></h3></th>
</tr>
<?php
}
?>
</tbody>

这是Javascript：
var TINY={};
function T$(i){return document.getElementById(i)}
function T$$(e,p){return p.getElementsByTagName(e)}
TINY.table=function(){
function sorter(n){this.n=n; this.pagesize=20; this.paginate=0}

for(i;i<t.w;i++){
var c=t.h.cells[i];
if(c.className!='nosort'){
c.className=this.head; c.onclick=new Function(this.n+'.wk(this.cellIndex)')
}
}
for(i=0;i<this.l;i++){t.a[i]={}}
if(f!=null){var a=new Function(this.n+'.wk('+f+')'); a()}
if(this.paginate){this.g=1; this.pages()}
};
sorter.prototype.wk=function(y){
var t=ge(this.e), x=t.h.cells[y], i=0;
for(i;i<this.l;i++){
t.a[i].o=i; var v=t.r[i].cells[y]; t.r[i].style.display='';
while(v.hasChildNodes()){v=v.firstChild}
t.a[i].v=v.nodeValue?v.nodeValue:''
}
for(i=0;i<t.w;i++){var c=t.h.cells[i]; if(c.className!='nosort'){c.className=this.head}}
if(t.p==y){t.a.reverse(); x.className=t.d?this.asc:this.desc; t.d=t.d?0:1}

if(this.currentid&&this.limitid){T$(this.limitid).innerHTML=this.d}
};
sorter.prototype.pages=function(){this.d=Math.ceil(this.l/this.pagesize)};
function ge(e){var t=T$(e); t.b=T$$('tbody',t)[0]; t.r=t.b.rows; return t};
function cp(f,c){
var g,h; f=g=f.v.toLowerCase(), c=h=c.v.toLowerCase();
var i=parseFloat(f.replace(/(\$|\,)/g,'')), n=parseFloat(c.replace(/(\$|\,)/g,''));
if(!isNaN(i)&&!isNaN(n)){g=i,h=n}

if(!isNaN(i)&&!isNaN(n)){g=i; h=n}
return g>h?1:(g<h?-1:0)
};
return{sorter:sorter}
}();
这是实际可工作的可排序表：
<?php
include('connect1.php');
$retrieve = $db->prepare("SELECT count(*) FROM Asset");
$retrieve->execute();
$fetchrow = $retrieve->fetch(PDO::FETCH_NUM);
$calculated=$fetchrow[0];
?>
<script type="text/javascript">
function UpdateCost() {
var sum = 0;
var gn, elem;
for (i=0; i<<?php echo $calculated ?>; i++) {
gn = 'sum_m_'+i;
elem = document.getElementById(gn);
if (elem.checked == true) { sum += Number(elem.value); }
}
document.getElementById('totalcost' ).value = sum.toFixed(0);
}
window.onload=UpdateCost
