Test if the HTML attribute is present and get the value

Question

I am trying to test if the HTML attribute is present and get the value using has Attribute("tabindex") property. But I am getting the below error:

Unable to get property 'hasAttribute' of undefined or null reference

I am using jGrid and jQuery. If the attribute is present I am trying to get the value of that particular td.

Please refer to the code below:

<tr class="jqgrow ui-row-ltr ui-widget-content  myAltRowClassEven ui-state-highlight" tabindex="0" id="2" role="row" aria-selected="true">
    <td aria-describedby="jqGrid11_cname" title=" TESTTHIS" class="zeroBorderRight" style="text-align: left; height: 20px;" role="gridcell">
        TESTTHIS
    </td>
</tr>
