javascript - 我可以在单个警报中对 javascript 数组的所有元素进行alert() 吗？

Question

我有一个像这样的简单 HTML 表格:

<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>

JavaScript/jquery 代码如下所示:

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

我在此 javascript 函数中尝试执行的操作是将 scannedArr 数组的元素全部包含在单个警报() 中。我可以这样做吗？有更简单的方法吗？

提前致谢!

试试这个

alert(scannedArr.join(''));
