如何从HTML中获取价值

    $.ajax({
type: "POST",
url: url,
success: function(msg){
alert(msg);
  }
data: "html"
});

after this, a html should be returned. But how can you fill textbox from a html file. So, for example

if the html contains following part:

    <tr><td class="tabelrow">Name:</td><td class="data">software</td></tr> 

a textbox should be filled with the word software.

I hope this is a bit clear.

If I understand you correctly you want something like:

$.ajax({
  type: "POST",
  url: url,
  success: function(msg){
    alert($(html).find(".data").text());
  }
  data: "html"
});

$('#textBoxId').val($(html).find(".data").text());
