我有选中嵌套的复选框来更改范围值,但我的问题是当我有两个或更多选择时...我不擅长javascript = /
如何解决问题:在第二次选择中选择2之后选择第一个选择值2,然后选择第二个0和第一次选择0总计必须为0但我不知道,怎么做它= /
<div id="test_div">
<input class="test_class" type="checkbox" value="3,00"/>3,00
<input class="test_class" type="checkbox" value="5,00"/>5,00
<input class="test_class" type="checkbox" value="10,00"/>10,00
<input class="test_class" type="checkbox" value="15,00"/>15,00
<select class="test_class">
<option value="10,00">0</option>
<option value="10,00">1</option>
<option value="10,00">2</option>
</select>
<select class="test_class">
<option value="10,00">0</option>
<option value="10,00">1</option>
<option value="10,00">2</option>
</select>
<select class="test_class">
<option value="10,00">0</option>
<option value="10,00">1</option>
<option value="10,00">2</option>
</select>
<span id="total">0,00</span><br/>
</div>
JS:
$(function()
{
var last = 0;
$('body').on('change','.test_class', function()
{
var vt = parseFloat($('#total').html().replace(',','.'));
if($(this).is('input:checked'))
{
var val = parseFloat($(this).val().replace(',','.'));
total = val + vt;
}else if($(this).is('input'))
{
var val = parseFloat($(this).val().replace(',','.'));
total = vt - val;
}
if($(this).is('select'))
{
var val = parseFloat($(this).val().replace(',','.'));
var index = $(this).prop('selectedIndex');
if(index == 0)
{
if(last > 0)
{
total = vt - val*last;
}
last = 0;
}
if(index == 1)
{
if(last == 2)
{
total = vt - val;
}else
{
total = vt + val*index;
}
last = 1;
}
if(index == 2)
{
if(last == 1)
{
total = vt + val;
}else
{
total = vt + val*index;
}
last = 2;
}
}
total = total.toFixed(2).replace('.',',');
$('#total').html('').html(total);
});
});

$("select .test_class").change(function() {
var total;
total = 0;
$("select .test_class").each(function() {
total += parseInt($(this).value);
});
$("#total").text(total + ".00");
});
