How to exclude span tags from j query element content

<td>6666<span class="copy">[复制]</span></td>

 

I want to achieve click to copy pop-up 6666 content

Code:

<script type="text/javascript" src="jquery-1.8.0.min.js"></script>
<script>
    $ (function ()
    {
        $ (".copy").bind ("click", function ()
        {
            var test = $($ (this).prop ('previousSibling')).text();
            console.log (test);
        })
    })
</script>

 

 

Requirements in the project:

<tr id="tr">

 <td class="t-left">

<span class="prev_span">

<span class="vsStyle_node vsStyle_blank"></span>

</span>

<span arrow="true" class="vsStyle_active_node vsStyle_shut"></span>

Fuzhou

</td>

 <td>Other Content1</td>

<td>Other Content</td>

</tr>

Requirements: Need to replace Fuzhou with other characters. Do not change the style in the td.

//Assignment operation $("#tr") has the same effect

 $("tr[id='tr']).find("td:first").prop("lastChild").nodeValue="赣州市";

 

Note: Using jQuery1.4.4 in the project will not find the prop method, and the problem will be solved after using 1.9.
