推荐答案

HtmlAgilityPack将在服务器端使用.根据您的陈述，您正在尝试在客户端而不是在服务器端声明一个值.

HtmlAgilityPack is to be used at server side. from what you stating, you are trying to assert a value at client side, not at the server side.

一旦ajax调用完成，您应该考虑使用jquery/javascript.

you should look into using jquery/javascript once the ajax call is done.

ajax ({ ....
  .done(...) {
    // handling the return result...
    alert($("#yourHtmlId").val()); // show one of your html tag value attribute.
  }   
})
