I am currently trying to implement an Add functionality to my page. Currently, the add is already functioning but I have to refresh the page in order for the newly added row to appear on the table.
Please see my codes below:
This is how I generate my table:
<table class="webGrid" id="ProductsTable">
<tr>
<td><strong><span>ProductID</span></strong></td>
<td><strong><span>ProductName</span></strong></td>
<td><strong><span>Price</span></strong></td>
<td colspan="2"><strong><span>Action</span></strong></td>
</tr>
@foreach (var item in repository.GetAllProducts(ViewData["BranchCode"].ToString()))
{
<tr>
<td><span class="ProductID">@item.ProductID</span></td>
<td><span class="ProductName">@item.ProductName</span></td>
<td><span class="Price">@item.Price</span></td>
<td>@Html.ActionLink("Edit", "Edit", new { RecordID = item.RecordID }, new { @class = "editLink" })</td>
<td>@Html.ActionLink("Delete", "Delete", new { RecordID = item.RecordID }, new { @class = "editLink" })</td>
</tr>
}
Currently, the edit and delete are already functioning well. Below is how I do the edit:
function update(data) {
if (data.Success == true) {
var parent = linkObj.closest("tr");
parent.find(".ProductID").html(data.Object.ProductID);
parent.find(".ProductName").html(data.Object.ProductName);
parent.find(".Price").html(data.Object.Price);
}
else {
$("#update-message").html(data.ErrorMessage);
$("#update-message").show();
}
}
Now I am trying to implement an add functionality which is almost the same as the edit jquery i am using. I have tried using the .append
method unsuccessfully.
EDIT:
I have tried using the code below for the add. But it doesn't seem to do anything. Or perhaps I'm doing something wrong:
function add(data) {
if (data.Success == true) {
var rowTemplate = $("#rowTemplate").html();
var tbl = document.getElementById("ProductsTable");
var counter = $("#ProductsTable tr").length;
data.Counter = counter;
$("#ProductsTable").append(applyTemplate(rowTemplate, data));
}
else {
$("#update-message").html(data.ErrorMessage);
$("#update-message").show();
}
}
function applyTemplate(template, data) {
var str = template;
if ($.isPlainObject(data)) {
$.each(data, function (index, value) {
var find = new RegExp("\\$1" + index, "ig");
str = str.replace(/\$/g, "\$1");
str = str.replace(find, value);
});
}
return str;
}
It makes use of a row template such as the following:
<script type="text/x-template" id="rowTemplate">
<tr><td><input type="text" id="txtName_$Counter" value="" /></td></tr>
</script>
I just found this solution online but I can't make it to work. I also tried the code below (i just made up based on the edit jquery I have):
function add(data) {
if (data.Success == true) {
var parent = linkObj.closest("tr");
parent.find(".ProductID").append(data.Object.ProductID);
parent.find(".ProductName").append(data.Object.ProductName);
parent.find(".Price").append(data.Object.Price);
}
else {
$("#update-message").html(data.ErrorMessage);
$("#update-message").show();
}
}
EDIT:
Right now, this is how my jQuery looks like:
function add(data) {
if (data.Success == true) {
data = { Counter: 3 };
$("#rowTemplate").tmpl(data).appendTo("#ProductsTable");
$('#updateDialog').dialog('close');
}
else {
$("#update-message").html(data.ErrorMessage);
$("#update-message").show();
}
}
and this is my template:
<script type="text/x-template" id="rowTemplate">
<tr>
<td><span class="ProductID"></span></td>
<td><span class="ProductName"></span></td>
<td><span class="Price"></span></td>
<td>@Html.ActionLink("Edit", "_EditProduct", new { @class = "editLink" })</td>
<td>@Html.ActionLink("Delete", "_DeleteProduct", new { @class = "editLink" })</td>
</tr>
</script>
Thanks to Sir @Muhammad Adeel Zahid for helping me make the jQuery work to add rows. However, it only adds a new row to my table. What I need now is to make it add the values I have from the data
object in the add function
of the jQuery.
I have tried following the tutorial from THIS LINK but I can't seem to make it work. My code is below:
function add(data) {
if (data.Success == true) {
var prod = $.map(data.results, function (obj, index) {
return {
ProductID: obj.text,
ProductName: obj.text,
Price: obj.text
};
});
prod = { Counter: 3 };
$("#rowTemplate").tmpl(prod).appendTo("#ProductsTable");
$('#updateDialog').dialog('close');
}
else {
$("#update-message").html(data.ErrorMessage);
$("#update-message").show();
}
}
Thanks a lot for helping!

I think there is something wrong with your template code. Please try changing it to
<script type="text/x-jquery-tmpl" id="rowTemplate">
<tr><td><input type="text" id="txtName_${Counter}" value="" /></td></tr>
</script>
and then generate html from it like
var obj = {Counter:3};
$("#rowTemplate").tmpl(obj).appendTo("#ProductsTable");
Edit
First I thought you were using jquery template engine and my answer was based on that assumption. you can find how to use templating engine here. Please see that i have also edited the type field in <script type="text/x-jquery-tmpl" ...
. Import jquery template js file in your code and leave rest of the things as is. It should work then.
Edit 2
Ok that is a different template. Remember you must have unique id for each of your template. That template would look like
<script type="text/x-jquery-tmpl" id="rowTemplate2">
<tr>
<td><span class="ProductID">${ProductId}</span></td>
<td><span class="ProductName">${ProductName}</span></td>
<td><span class="Price">${Price}</span></td>
<td>@Html.ActionLink("Edit", "_EditProduct", new { @class = "editLink" })</td>
<td>@Html.ActionLink("Delete", "_DeleteProduct", new { @class = "editLink" })</td>
</tr>
</script>
Note how you add placeholders ${Variable}
in the templates. Now when you need to use the template, you will need a json object with properties matching the variables used in the template. For example to use above template, I would do something like
var obj2 = {ProductId:2,ProductName:'First Product', Price: 323};//note the properties of json and template vars match.
$("#rowTemplate2").tmpl(obj2).appendTo("#somecontainer");
