我必须构建一个表单,并且我一直在使用jQuery,但是如果您能给我任何建议,我会陷入第一步,
所以,让我解释一下我有20种产品的形式,其中有offer1,offer2和月费,到目前为止,所有这些都可以正常使用,我只需要在选择了特定产品的数量之后,然后按下一个按钮再次显示结果,但仅显示填充量,因此基本上只显示客户对它们感兴趣的产品,这是我的主要问题,我知道我必须在jQuery中执行每个函数,但是我不确定该怎么做它吗?
我在表格上附加了图片,因此您可以看到一个示例 form picture
编辑: 这是我目前的代码:
function convert(value) {
return "" + ((Number(value) || 0).toFixed(2).replace(/(\d)(?=(\d{3})+
(?!\d))/g, "$1,")) + "";
}
function testing(id, normaloffer, talesalesoffer, montlyoffer) {
var normaoffertotal = normaloffer * $('#amount' + id).val();
var talesalestotal = talesalesoffer * $('#amount' + id).val();
var montlytotal = montlyoffer * $('#amount' + id).val();
$(".normaloffertotal" + id).html(normaoffertotal);
$(".telesalesoffertotal" + id).html(talesalestotal);
$(".montlytotal" + id).html(montlytotal);
$('#hnoffer' + id).val(normaoffertotal);
}
console.log(convert(10496.470000000001));
function normaloffertotalcalc() {
var sumnormaltotal = 0;
$('span[id^="normaloffertotalspan"]').each(function () {
var text = $(this).text();
sumnormaltotal += parseFloat(text, 10);
});
$('#sumnormaltotal').html(sumnormaltotal);
var sum_telesale = 0;
$('span[id^="telesalesoffertotalspan"]').each(function () {
var text = $(this).text();
sum_telesale += parseFloat(text, 10);
});
$('#sumtelesaletotal').html(sum_telesale);
var sum_montly = 0;
$('span[id^="montlyofferspan"]').each(function () {
var text = $(this).text();
sum_montly += parseFloat(text, 10);
});
$('#summontlytotal').html(sum_montly);
console.log('Normal Total Offer ' + convert(sum_normal));
console.log('TeleSales Total Offer ' + convert(sum_telesale));
console.log('Montly Total Offer ' + convert(sum_montly));
}
</script>
这是html
<?php
$count = 0;
$query = mysqli_query($con, "SELECT * FROM products");
while ($row = mysqli_fetch_array($query)) {
$count++;
?>
<tr>
<td align="center"><?= $row[1] ?></td>
<td align="center"><input type="text" placeholder="0" id="amount<?= $count ?>"
name="amount<?= $count ?>" onblur="normaloffertotalcalc()"
onkeyup="testing(<?= $count ?>, <?= $row[2] ?>, <?= $row[3] ?>, <?= $row[4] ?>)"
style="-webkit-appearance: none; background: none; text-align: center; border: none; width: 40px;">
</td>
<td align="center">£<?= $row[2] ?></td>
<td align="center">£<span class="normaloffertotal<?= $count ?>"
id="normaloffertotalspan">0</span> <input type="hidden"
class="normaloffertotalspan"
id="hnoffer<?= $count ?>">
</td>
<td align="center">£<?= $row[3] ?></td>
<td align="center">£<span class="telesalesoffertotal<?= $count ?>" id="telesalesoffertotalspan">0</span>
</td>
<td align="center">£<?= $row[4] ?></td>
<td align="center">£<span class="montlytotal<?= $count ?>" id="montlyofferspan">0</span></td>
</tr>
<?php } ?>
答案 0 :(得分:0)
我为此问题找到了解决方案
$('input[type=text]').each(function(){
var val = parseInt($(this).val());
if(val > 0){
var id = $(this).attr('id');
if(id){
console.log(id);
}
console.log(val);
}
});
这是我所做的代码,并且运行良好:)
感谢所有给我建议的人
还有一件事情,您是否知道我该如何从MySQL中仅导出ID为2,7,1的产品:)
