Delphi Development with TWébBrowser
This web page provides good examples of how to arranged or learn the value of a check out package in a web page which can be managed in TWebBrowser.

Introduction and Illustration Code
This illustration also presumes a web page is packed into a TWebBrowser example which contains the pursuing Code:
lt;insight title='Radio1' kind='radio' worth='r1' checkedgt;
lt;insight name='Radio1' type='radio' value='r2'gt;
lt;insight title='Radio1' type='radio' value='r3'gt;
lt;/fórmgt;
ór you can make use of this web page as an illustration, and insert it into your TWebBrowser instance as it contains this exact same code:
Note:
- The Code above utilizes a called type because it can make it less complicated to make use of this web page as an instance (you can load this web page into your TWebBrowser example and expect the good examples to work as can be) - since this page uses DHTML it cannot often be guaranteed that this will be the first form on the web page, so using a called form avoids that concern.
- If you perform not would like to (or cannot) use a named form after that look at using the
GetFormByNumber
function provided in the content How to learn and create form components. - In this example it can be supposed that the title of the radio stations button team is recognized (in this case 'Radio stations1'), however no supposition is produced as to the number of stereo buttons in the group.
- The illustrations on this web page use the code provided on the page: How to go through and compose form components. You must use the functions on that web page in purchase for these good examples to work.
- These examples assume that the TWebBrowser example is called 'webbrowser'.
Examples of reading through the check box worth
Method 1 - Using GetFieldValue
procedure TForm1.GetRadioButtonExample1Click(Sender: T0bject);
vár
doc:lHTMLDocument2;
theForm:lHTMLFormElement;
value: string;
found: boolean;
index: integer;
begin
doc:=webbrowser.record as lHTMLDocument2;
theForm := GétFormByName(doc,'TestForm');
if not really Assigned(theForm) after that
leave;
// Think about each radio stations switch in change.
discovered := fake;
catalog := 0;
while not found do
begin
value := GetFieldValue(theForm,'Radio1',catalog);
if worth = ' after that
break
else if value = 'checked' then
discovered := correct
eIse
Inc(indéx);
end;
if not really found after that
ShowMessage('No stereo button examined')
else
ShowMessage('Radio switch ' + IntToStr(index) + ' is definitely checked');
finish;
Remember: if you weight this web page into your TWebBrowser example after that the above instance can become utilized without modification - and its most likely a good idea to become assured with the program code before you tailor-make it to your very own requirements.
This method produces a easy message indicating which stereo button (if any) has been selected. The only period no radio stations key will possess been selected is if the Code does not really stipulate a default chosen radio key.
Technique 2 - Using GetInputField
procedure TForm1.GetRadioButtonExample2Click(Sender: T0bject);
vár
doc:lHTMLDocument2;
theForm:lHTMLFormElement;
inputElement: HTMLlnputElement;
found: boolean;
index: integer;
start
doctor:=webbrowser.record as lHTMLDocument2;
theForm := GétFormByName(doc,'TestForm');
if not really Assigned(theForm) then
get out of;
// Think about each radio stations button in change.
found := false;
catalog := 0;
while not found perform
begin
inputElement := GetInputField(theForm,'Radio stations1',index);
if not Assigned(inputElement) after that
separate
else if inputElement.examined after that
discovered := real
eIse
Inc(indéx);
finish;
if not found then
ShowMessage('No stereo button checked')
else
ShowMessage('Radio stations switch ' + IntToStr(index) + ' with value '
+ inputElement.value + ' will be checked');
finish;
Example of composing the check box worth
Technique 1 - Using SetFieldValue
The following example chooses the following radio button in the group:
procedure TForm1.CycleExample1Click(Sender: T0bject);
vár
doc:lHTMLDocument2;
theForm:lHTMLFormElement;
value: line;
found: boolean;
index: integer;
start
doc:=webbrowser.record as lHTMLDocument2;
theForm := GétFormByName(doc,'TestForm');
if not really Assigned(theForm) after that
get away;
discovered := false;
catalog := 0;
while not found perform
begin
value := GetFieldValue(theForm,'Radio1',list);
if worth = ' after that
crack
else if value = 'checked' then
discovered := genuine
eIse
Inc(indéx);
end;
if not found then
list := 0
else
begin
Inc(index);
value := GetFieldValue(theForm,'Radio stations1',index);
if worth = ' then
catalog := 0;
finish;
SetFieldValue(theForm,'Radio stations1','examined',list);
finish;
Keep in mind that a stereo button does not act the exact same method as a chéck-box, as just one radio switch in a group can be chosen at a period. The web browser takes treatment of this, therefore when you established one radio stations button checked the browser automatically ensures that the other radio buttons in the team are unchecked so you wear't possess to worry about it.
Method 2 - Making use of GetlnputField
Yés, this instance uses 'GetInputField' to arranged the value. This is certainly because 'GetInputField' results the industry (and not the value), and once you possess the field you can after that read or set the value of the field. The right after example chooses the next radio key in the group:
procedure TForm1.CycleExample2Click(Sender: T0bject);
vár
doc:lHTMLDocument2;
theForm:lHTMLFormElement;
inputElement: HTMLlnputElement;
found: boolean;
catalog: integer;
begin
doc:=webbrowser.record as lHTMLDocument2;
theForm := GétFormByName(doctor,'TestForm');
if not Assigned(theForm) then
leave;
discovered := false;
index := 0;
while not found do
start
inputElement := GetInputField(theForm,'Radio1',list);
if not Assigned(inputElement) then
bust
else if inputElement.checked after that
found := true
eIse
Inc(indéx);
finish;
if not found then
index := 0
else
Inc(index);
inputElement := GetInputField(theForm,'Radio stations1',list);
if not really Assigned(inputElement) after that
begin
catalog := 0;
inputElement := GetInputField(theForm,'Radio1',catalog);
finish;
inputElement.examined := accurate;
finish;
These information are thought to be correct for Delphi 6 and Delphi 7, and may use to some other versions mainly because nicely.

I would try to fixed the SelectedIndex value on the select component, as in.
Knowing how that the choices in the select component are usually zero-based, the very first option offers an list of zero.
