[英]How to convert an HTML table to plain text and save it into a variable in JavaScript
我正在檢查站點,發現JavaScript:如何從字符串中剝離HTML標簽? 但這並不能真正說明如何進行此操作:
<tr id="element.incident.comments.additional">
<td colspan="2">
<span style="">
<table cellpadding="0" cellspacing="0" style="table-layout:fixed" width="100%">
<tbody>
<tr>
<td colspan="2">
<hr>
</td>
</tr>
<tr style="">
<td class="tdwrap"><strong>2014-01-23 14:45:40 - <a style="color:blue" href="sys_user.do?sysparm_view=itil&sysparm_query=user_name=Superhero@superhero.com">SuperHero</a></strong></td>
<td align="right" nowrap="true"><sup>Additional comments</sup></td></tr>
<tr style="">
<td colspan="2"><span style="word-wrap:break-word;">received from: SDUperhero@superhero.com<br><br>lalalalalala
<br>lotsofwords<br><br><br><br><br><br>
The information transmitted, including any attachments, is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material</span></td></tr></tbody></table></span></td>
</tr>
並獲取里面的文本:
<tr id="element.incident.comments.additional">
進行進一步解析。
我嘗試過
function strip(html)
{
var tmp = document.createElement("DIV");
tmp.innerHTML = html;
return tmp.textContent||tmp.innerText;
}
var commentsField = document.getElementById("element.incident.comments.additional").innerHTML;
alert(strip(commentsField));
但是我不確定這是否是正確的方法,因為我沒有收到任何警報。
有什么想法嗎?
因為你有.
在您的ID中,您將需要在jQuery選擇器中對其進行轉義:
$("#txt").val($("#element\\.incident\\.comments\\.additional").html());
那應該起作用。
