:JavaScript的
$("[id^=total_price_ht]").calc(
// the equation to use for the calculation
"qty * price",
{
qty: $("[id^=unit_quantity_]"),
price: $("[id^=unit_price_ht_]")
},
function (s){
// return the number as a dollar amount
return "$" + s.toFixed(2);
}
);
:HTML
<tr id="lines[0]">
<td>
<input id="0" type="checkbox" class="hiddenCheckbox">
<label for="0" class="prettyCheckbox checkbox list"><span class="holderWrap" style="width: 18px; height: 19px; "><span class="holder" style="width: 18px; "></span></span></label>
</td>
<td>
<input class="required" name="lines[0][title]" placeholder="Title" type="text">

<td>
<input name="lines[0][description]" placeholder="Description" type="text">
</td>
<td>
<input class="required" id="unit_quantity_0" name="lines[0][quantity]" placeholder="Quantité" type="text" value="0,00">
</td>
<td>
<input class="required" id="unit_price_ht_0" name="lines[0][unit_price_ht]" placeholder="Prix unit. HT" type="text" value="0,00">
</td>
<td class="price" id="total_price_ht_0">$0.00</td>
</tr>
页面加载后,我可以在total_price_ht字段中看到“$ 0.00”,但是当我更改数量或价格时,它的值不会改变。
我做错了什么?感谢。

我想你每次想要重新计算总数时都需要调用calc
插件:
$("[id^='unit_quantity_'], [id^='unit_price_ht_']").keyup(recalc);
function recalc() {
$("[id^='total_price_ht']").calc(
// the equation to use for the calculation
"qty * price", {
bind: "keyup",
qty: $("[id^='unit_quantity_']"),
price: $("[id^='unit_price_ht_']")
}, function(s) {
// return the number as a dollar amount
return "$" + s.toFixed(2);
});
}
recalc();
