Question

我正在尝试代理一个函数，以便我只是替换部分页面而不是重新加载整个页面。

<div id="content" style="display:none;">
</div>
<div class='contentitem' id='restart' style="margin-top: 100px; margin-left: 100px; margin-bottom: 100px; display:block;">
    <table>
        <tr>
            <td></td>
            <td><p style="font-size: 1.2em; font-weight: bold;"><%=translate([==[Loading...]==])%></p></td>
        </tr>
    </table>
</div>

<script type="text/javascript">

<script type="text/javascript" src="/jquery-1.9.1.min.js"></script>

<script type="text/javascript">
    var content = $("#content");

    $(document).ready(function(){   
        content.load('/cgi/b/sfltr/cfg/ div .contentitem', function(content) {
        $(this).find('tbody').each(function(){
              $("span:contains('Content Based Filtering')").closest("table").remove();
          });

当我使用该功能提交表单时，帖子有效，200OK包含我要解析的页面。

我不明白的是：

为什么我开始加载嵌入式脚本（嵌入在200OK中的代码脚本）， =＆GT;可能是因为我在将其过滤之前将其设置在div中，但我认为这是实现它的唯一方法。我应该创建一个新的XHR对象来存储它，然后过滤该对象并使用生成的.html（）设置DIV吗？如果是这样，有人能给出一个小例子吗？
为什么我最终会收到错误，因为它会覆盖我正在使用的JavaScript（无论如何都应该是完全相同的代码）

Answer 1

我在这里找到了答案。似乎在使用数据类型“html”时，它将始终执行嵌入的js。这解决了这个问题： prevent jquery ajax to execute javascript from script or html response

错误是因为嵌入式JS工作所需的一些项目在此上下文中不可用。

非常感谢。
