我可以在单个警报中提醒()javascript数组的所有元素吗？

Question

我有一个像这样的简单HTML表:

<table>
    <thead>
        <tr>
            <th id="lname"><span title="sort this column">Last Name</span>
            </th>
            <th id="fname"><span title="sort this column">First Name</span>
            </th>
            <th id="scanned"><span title="sort this column">Scanned In</span>
            </th>
            <th id="department"><span title="sort this column">Department</span>
            </th>
            <th id="category"><span title="sort this column">Category</span>
            </th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td class="blah">LNAME1</td>
            <td>FNAME1</td>
            <td>06/25/13 12:48 PM</td>
            <td>Internal Medicine</td>
            <td>Fellow</td>
        </tr>
        <tr>
            <td class="blah">LNAME1</td>
            <td>FNAME1</td>
            <td>06/25/13 12:48 PM</td>
            <td>Internal Medicine</td>
            <td>Fellow</td>
        </tr>
        <tr>
            <td class="blah">LNAME1</td>
            <td>FNAME1</td>
            <td>06/26/13 07:29 AM</td>
            <td>Internal Medicine</td>
            <td>Faculty</td>
        </tr>
        <tr>
            <td class="blah">LNAME1</td>
            <td>FNAME1</td>
            <td>06/26/13 07:21 AM</td>
            <td>Internal Medicine</td>
            <td>Faculty</td>
        </tr>
    </tbody>
</table>

一个javascript/jquery代码是这样的:

var count = 0;
var scannedArr = new Array();
$('table tr').each(function(){
    var times = $(this).find('.blah').text();
    scannedArr[count] = times;
    count++;
});

我在这个javascript函数中尝试做的是scannedArr在一个alert()中包含数组的元素.我能这样做吗？有没有更简单的方法呢？

提前致谢!

试试这个

alert(scannedArr.join(''));
