make table row clickable + Hover change background

Question

I have a MVC application and I want to make my table row clickable and then when I hover over it, I want to change the background of it.

I have the following code that I got from a blog

<script type="text/javascript">
   $(document).ready(function () {
      $('#example tbody tr').click(function () {
          alert('row was clicked');
      });
  });     

</script>

I wanted to add the hover capability, so I modified it to:

$<script type="text/javascript">
    $(document).ready(function () {
         $('#example tbody tr').click(function () {
             alert('row was clicked');
         });
    });

   $(document).ready(function () {
        $('#example tbody tr').hover(function () {
            $(this).css('background-color','#ccc');
        }, function () {
            $(this).css('background-color','#fff');
   });
</script>

my HTML:

<table id="example" border = "2">
    <thead>
    <tr style="border-style:solid"  class="simplehighlight">
        <th>
            Name
        </th>
        <th>
            Description
        </th>
        <th>
            tblStatu
        </th>
        <th>
            DueDate
        </th>
        <th>
            AssignedTo
        </th>
        <th>
            CreatedOn
        </th>
        <th>
            CreatedBy
        </th>
        <th>
            ModifiedOn
        </th>
        <th>
            ModifiedBy
        </th>
        <th></th>
    </tr>
    </thead>


    <tbody>
@foreach (var item in Model)
{
    <tr style="border-style:solid">
        <td style="border-style:solid">
            @item.Name

            @*@Html.DisplayFor(modelItem => item.Name)*@
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Description)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.tblStatu.Name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.DueDate)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.AssignedTo)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.CreatedOn)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.CreatedBy)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ModifiedOn)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ModifiedBy)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id = item.TaskId }) |
            @Html.ActionLink("Details", "Details", new { id = item.TaskId }) |
            @Html.ActionLink("Delete", "Delete", new { id = item.TaskId })
        </td>
    </tr>
}
   </tbody> 

The click handler works, but the hover over function doesn't. What could be the problem?

Answer 1

After adding the code from your comment into the question, I noticed that you're missing a closing }); on your second document ready handler. Try the following. Notice I'm using one ready handler and chaining the jQuery functions to the same selector -- part of the beauty of jQuery.

$<script type="text/javascript">
    $(document).ready(function () {
        $('#example tbody tr').click(function () {
             alert('row was clicked');
        }).hover(function () {
              $(this).css('background-color','#ccc');
           }, function () {
              $(this).css('background-color','#fff');
        });
    });
</script>

As @Chris Pietschmann notes, though, you could get the same effect with CSS which gives you less code to maintain.

<style>
#example tbody tr:hover
{
    background-color: #ccc;
}
</style>

You can use CSS to define a different background color on hover:

tr:hover
{
    background: red;
}
