我有一个 javascript 代码，我正在使用 jQuery Calculation 插件（可以从链接文本下载）。我的表格有点像购物车表格，即价格根据输入的数量更新。该表格有接受数字的文本框，这表示数量。输入/修改此数量后，将更新相同的价格，同时更新总计。目前，它只允许我使用文本框。我希望能够在表单中使用复选框和下拉列表，并希望 JS 代码处理更新价格和总计并立即显示（就像在当前现有文本框的情况下一样）。我在我的本地主机上尝试了这个，但我已经结束了当前的功能，或者更新的代码不适用于复选框和下拉列表。
我到目前为止的表格是：
<script src="js/jquery-1.3.2.min.js" type="text/javascript"></script>
<script src="js/jquery.calculation.js" type="text/javascript"></script>
<SCRIPT type="text/javascript">
var bIsFirebugReady = (!!window.console && !!window.console.log);
$(document).ready(
function (){
// update the plug-in version
$("#idPluginVersion").text($.Calculation.version);
// bind the recalc function to the quantity fields
$("input[name^=qty_item_]").bind("keyup", recalc);
// run the calculation function now
recalc();
// automatically update the "#totalSum" field every time
// the values are changes via the keyup event
$("input[name^=sum]").sum("keyup", "#totalSum");
// automatically update the "#totalAvg" field every time
// the values are changes via the keyup event
$("input[name^=avg]").avg({
bind:"keyup"
, selector: "#totalAvg"
// if an invalid character is found, change the background color
, onParseError: function(){
this.css("backgroundColor", "#cc0000")
}
// if the error has been cleared, reset the bgcolor
, onParseClear: function (){
this.css("backgroundColor", "");
}
});

// you can use this to format the value
$(options.selector).val(value);
}
});
// this calculates the sum for some text nodes
$("#idTotalTextSum").click(
function (){
// get the sum of the elements

$("#totalTextSum").text("$" + sum.toString());
}

// this calculates the average for some text nodes
$("#idTotalTextAvg").click(
function (){

var avg = $(".textAvg").avg();
// update the total
$("#totalTextAvg").text(avg.toString());
}
);
}
);
function recalc(){
$("[id^=total_item]").calc(
// the equation to use for the calculation
"qty * price",
// define the variables used in the equation, these can be a jQuery object

function ($this){

var sum = $this.sum();
$("#grandTotal").text(
// round the results to 2 digits
"$" + sum.toFixed(2)
);
}
);
}

同样如您所见，上面的表单代码中使用了表格。有没有办法在不使用表格的情况下实现我想要做的事情？
谢谢大家。
