我被困在了我正在處理的這個jQuery自動計算腳本的最後部分。我想根據「單選按鈕點擊」自動重新計算小計值。當單擊單選按鈕「special_(n)」時,計算會自動添加10%的折扣。基於單選按鈕的jQuery自動計算單擊
查看這裏的行動腳本:http://www.ppleasysavings.com/calcscript/index.html (TIP):輸入一個值的「數量」字段,以及總計將自動計算。
這裏是HTML「部分」
Yes<input name="special_1" type="radio" value="1" />
No<input name="special_1" type="radio" value="0" />
<input name="total_item_1" type="text" id="total_item_1" style="text-align:right;" value="$0.00" size="7" maxlength="8" readonly="readonly">
Yes<input name="special_2" type="radio" value="1" />
No<input name="special_2" type="radio" value="0" />
<input name="total_item_2" type="text" id="total_item_2" style="text-align:right;" value="$0.00" size="7" maxlength="8" readonly="readonly">
這裏是jQuery的
正如你所看到的,我已經添加了一些代碼,包括特殊的「單選按鈕「,並已開始公式=>數量*價格*特殊。現在,我需要修改它,以便它能夠正常工作。
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);
$("input[name^=special_]").bind("checked", recalc);
// run the calculation function now
recalc();
}
);
function recalc(){
$("[id^=total_item]").calc(
// the equation to use for the calculation
"qty * price * special",
// define the variables used in the equation, these can be a jQuery object
{
qty: $("input[name^=qty_item_]"),
price: $("[id^=price_item_]"),
special: $("input[name^=special_]")
},
// define the formatting callback, the results of the calculation are passed to this function
function (s){
// return the number as a dollar amount
return "$" + s.toFixed(2);
},
// define the finish callback, this runs after the calculation has been complete
function ($this){
// sum the total of the $("[id^=total_item]") selector
var sum = $this.sum();
$("#grandTotal").val(
// round the results to 2 digits
"$" + sum.toFixed(2)
);
}
);
}
