JQuery template fill table problem. Need help

I have table data coming from db using $.ajax. The data is not filling right. Can someone please fix the code.

This is in javascript file

var ReloadGrid = (function(){
            $.getJSON("/HeaderMenu/GetHeaderGrid", function(data) {
                $( "#gridTemplate" ).tmpl(data).appendTo( "#mytemp" );
            });
 });

Below is in mvc3 razor page. Problem is the "mytemp" is not filling instead showing columns at the top of header returning 3 rows. num++ not working don't know where to initalize it required as counter.

<script id="gridTemplate" type="text/x-jquery-tmpl">
    <tr class="gridRow">
        <td class="numberi开发者_如何学编程ngTd">
            var num = 1;
            num = num++

        </td>
        <td class="cellTd">
            <input id="index" name="index" class="numberField" type="text" value="${IndexOrder}" />
        </td>
        <td class="cellTd">${DisplayName}</td>
        <td class="cellTd ">${UrlName} Us</td>
        <td class="cellTd ">${Active}</td>
    </tr>

</script>

<div class="gridDiv">
<table class="gridTable" cellspacing="0" cellpadding="0">
    <tr class="gridTitleRow">
        <td class="numberingTd width36">&nbsp;</td>

        <td class="iconLink width60">Sort Order</td>
        <td class="iconLink widthAuto">Display Name</td>
        <td class="iconLink widthAuto">Url Name</td>
        <td class="iconLink widthAuto">Active</td>
    </tr>
    <span id="mytemp" ></span>
</table>
</div>

I'm not sure what the data object looks like but you need to add a num property to each element. Assuming that data is an array of objects, then something like this should work:

$.getJSON('/HeaderMenu/GetHeaderGrid', function(data)
{
    for (var i=0; i<data.length; i++)
    {
        data[i].num = i;
    }

    $('#gridTemplate').tmpl(data).appendTo('table.gridTable > tbody');
});

As @Cory pointed out, you should not have a <span> in the middle of table. Use a <tbody>.

<table class="gridTable" cellspacing="0" cellpadding="0">
    <tbody>
        <tr class="gridTitleRow">
            <td class="numberingTd width36">&nbsp;</td>
            <td class="iconLink width60">Sort Order</td>
            <td class="iconLink widthAuto">Display Name</td>
            <td class="iconLink widthAuto">Url Name</td>
            <td class="iconLink widthAuto">Active</td>
        </tr>
    </tbody>
</table>

Try passing in the value of num instead of setting it in the template.

Also, you should not have a span in the middle of your table. Instead use a tbody tag.

var ReloadGrid = (function(){
            $.getJSON("/HeaderMenu/GetHeaderGrid", function(data) {
                data.num = $('#mytemp tr').length + 1;
                $( "#gridTemplate" ).tmpl(data).appendTo( "#mytemp" );
            });
 });

You can pass a function as a template option:

$('#gridTemplate').tmpl(jsonData, {
        getIndex: function () {
            return $.inArray(this.data, jsonData);
     }
}).appendTo( ".gridTable tbody" );

And then in your template:

<script id="gridTemplate" type="text/x-jquery-tmpl">
    <tr class="gridRow">
        <td class="numberingTd">${this.getIndex()}</td>
        <td class="cellTd">
            <input id="index" name="index" class="numberField" type="text" value="${IndexOrder}" />
        </td>
        <td class="cellTd">${DisplayName}</td>
        <td class="cellTd ">${UrlName} Us</td>
        <td class="cellTd ">${Active}</td>
    </tr>
</script>
