c#从隐藏输入中获取值

Question

Soo ive been trying to get the value from a hidden input and innertext from a span on a website (Note that i dont have access to edit the html code)

Code from website:

<input type="hidden" name="hidv" value="1582912961">
<span class="valo">0.888</span>

i could use a code similar to this but dont know the correct use of it:

    label5.Text = webBrowser2.Document.GetElementById("hidv").InnerText;
    label6.Text = webBrowser2.Document.GetElementById("valo").InnerText;

Answer 1

First I'd put an ID on the input tag

<input id="myId" type="hidden" name="hidv" value="1582912961">

Then you could use JS, jQuery, etc, to select the value.

$('#myId').val();

$('input[name=hidv]').val()

also just a note Document.GetElementById requires an Id. Otherwise, you could've done Document.GetElementsByClassName("valo") if you wanted to use the class name instead of an Id attribute.
