webbrowser提交radio的方法
<li class="" id="op8492">
<input id="option0" name="option" type="radio" value="8492" />
<label for="option0">

<li class="" id="op8493">

<li class="" id="op8495">
<input id="option3" name="option" type="radio" value="8495" />

以上是个radio,我想动态的按照id选择option0 checked或者option1 checked.....
请给段代码，高分送上

[解决办法]
var
doc: IHTMLDocument2;
inputElement: IHTMLInputElement;
begin
doc := wb1.Document as IHTMLDocument2;
inputElement := doc.all.item('option',0) as IHTMLInputElement; //item的第二个参数就是第几个radio
if Assigned(inputElement) and (inputElement.type_ = 'radio') then
inputElement.checked := True;
end;
[解决办法]

Delphi(Pascal) code

WebBrowser1.Navigate('javascript:document.getElementById("option0").checked=true;void(0);');
