In my view I'm displaying a table and in table I strongly typed dropdown list and as you change selected item it calls getPrice(int product_id) function through ajax call and returns price of selected item but it only works for 1st row.
<tr class="tr_clone" id="1">
<td>
@Html.DropDownListFor(model => model.product_id, ViewBag.ProductList as SelectList, "--select product--", new { @class = "form-control sel"}
</td>
<td class="product_price" id="product_price" style="text-align: center; font-size: 16px;">@Html.DisplayFor(model => model.product_price, "", "") </td></tr>
<tr class="tr_clone1" id="2">
<td>
@Html.DropDownListFor(model => model.product_id, ViewBag.ProductList as SelectList, "--select product--", new { @class = "form-control sel"})
</td>
<td class="product_price" id="product_price1" style="text-align: center; font-size: 16px;">@Html.DisplayFor(model => model.product_price, "", "")</td></tr>
$(function () {
$('#product_id').change(function () {
$.ajax({
type: "POST",
url: "/Home/GetPrice",
datatype: "Json",
data: { product_id: $('#product_id').val() },
success: function (data) {
document.getElementById('product_price').innerHTML = data;
multiply();
},
error: function (data = 0) {
document.getElementById('product_price').innerText = 0;
multiply();
}
});
});
});
@Html.DropDownListFor(model => model.product_id, ViewBag.ProductList as SelectList, "--select product--", new { @class = "form-control sel", @onchange = "gg(this)" })
<script>
function gg(x) {
$.ajax({
type: "POST",
url: "/Home/GetPrice // GetPrice is name of actionmathod of controller",
datatype: "Json",
data: { product_id: $(x).val() },
success: function (data) {
//your code here
},
error: function () {
// your code here
}
});
}
</script>
You need to set 2 different ids for each dropdown.
@Html.DropDownListFor(model => model.product_id, ViewBag.ProductList as SelectList, "--select product--", new { @id = "ddl_product_id_1", @class = "form-control sel"}
@Html.DropDownListFor(model => model.product_id, ViewBag.ProductList as SelectList, "--select product--", new { @id = "ddl_product_id_2", @class = "form-control sel"})
And write change event of individual that dropdown id.
Since you are selecting 2 different products, you model should have 2 id properties - product1_id and product2_id and 2 price properties - product1_price and product2_price
So fix your view accordingly
<tr class="tr_clone" id="1">
<td>
@Html.DropDownListFor(model => model.product2_id, ViewBag.ProductList as SelectList, "--select product--", new { @class = "form-control sel"}
</td>
<td class="product_price" id="product_price" style="text-align: center; font-size: 16px;">@Html.DisplayFor(model => model.product1_price, "", "") </td></tr>
<tr class="tr_clone1" id="2">
<td>
@Html.DropDownListFor(model => model.product2_id, ViewBag.ProductList as SelectList, "--select product--", new { @class = "form-control sel"})
</td>
<td class="product_price" id="product2_price" style="text-align: center; font-size: 16px;">@Html.DisplayFor(model => model.product2_price, "", "")</td></tr>
and you should 2 separate on change too
$(function () {
$('#product1_id').change(function () {
$.ajax({
type: "POST",
url: "/Home/GetPrice",
datatype: "Json",
data: { product_id: $('#product1_id').val() },
success: function (data) {
document.getElementById('product1_price').innerHTML = data;
multiply();
},
error: function (data = 0) {
document.getElementById('product1_price').innerText = 0;
multiply();
}
});
});
$('#product2_id').change(function () {
$.ajax({
type: "POST",
url: "/Home/GetPrice",
datatype: "Json",
data: { product_id: $('#product2_id').val() },
success: function (data) {
document.getElementById('product2_price').innerHTML = data;
multiply();
},
error: function (data = 0) {
document.getElementById('product2_price').innerText = 0;
multiply();
}
});
});
});
