Question

我有字符串需要在加载页面后替换或附加文本。请参阅HTML代码

<table cellpadding=2 cellspacing=0 width='100%' class='ms-informationbar'
    style='margin-bottom: 5px;' border=0>
   <tr>
    <td width=10 valign=center 
       style='padding: 4px'><img src='/_layouts/images/exclaim.gif' alt='' />
    </td>
    <td>Items on this list require content approval. Your submission will not
       appear in public views until approved by someone with proper rights. 
       <a href=javascript:HelpWindowKey("ContentApproval")>More information on 
       content approval.</a>
    </td>
   </tr>
 </table>
 <table cellpadding=2 cellspacing=0  
       width=100% class='ms-informationbar' style='margin-bottom: 5px;' border=0>
   </table>

现在我必须替换文字

  Items on this list require content approval. Your submission will not
       appear in public views until approved by someone with proper rights. 
       <a href=javascript:HelpWindowKey("ContentApproval")>More information on 
       content approval.</a>**

带

Items on this list require content approval. Your submission will not
  appear in public views until approved by someone with proper rights. 
  <a href=javascript:HelpWindowKey("ContentApproval")>More information on 
   content approval.</a> The editing session will timeout in 40 minutes

我们怎么做这个jQuery？

Answer 1

你可以这样做：

首先，在TD元素中放置一个类或id，以便您可以更容易地引用它：

<td class="ApprovalNotice">Items on this list require content approval. Your submission will not
       appear in public views until approved by someone with proper rights. 
       <a href=javascript:HelpWindowKey("ContentApproval")>More information on 
       content approval.</a>
    </td>

现在你可以这样做：

origHtml = $('.ApprovalNotice').html();
$('.ApprovalNotice').html(origHtml + yourText);

或者你可以做一些更简单的事情：

<td class="ApprovalNotice">Items on this list require content approval. Your submission will not
           appear in public views until approved by someone with proper rights. 
           <a href=javascript:HelpWindowKey("ContentApproval")>More information on 
           content approval.</a><span class="timeout" style="display:none;">your text goes here</span>        </td>

然后

$('.timeout').show();

Answer 2

将ID添加到您要更改的TD。

<td id="infoText">...</td>

然后你可以改变这样的内容

$('#infoText').html('New Text')

Answer 3

$(document).ready(function(){

$(".ms-informationbar tr td").eq(1).html('Items on this list require content approval. Your submission will not
  appear in public views until approved by someone with proper rights. 
  <a href=javascript:HelpWindowKey("ContentApproval")>More information on 
   content approval.</a> The editing session will timeout in 40 minutes');

});

这将选择在类.ms-informationbar的元素中的tr中找到的第二个td，并将其内容替换为引号之间的html。
