JQuery serialize on form is EMPTY (ajax/post/get)

 Hi All,

I had several times a problem, that the collected data by jQuery API's serialize() or serializeArray() was empty, although the inputs were not empty.

Follow these checkups to by pass the problem.

1] when the input don't name attribute the result will be empty.

<form id="form1">
        <input type="text" value="test value">
        <button>submit</button>
</form>

//$('#form1').serialize()  ==> "" (empty)

SOLUTION:

<form id="form1">
        <input type="text" value="test value" value="ANYNAME">
        <button>submit</button>
</form>

//$('#form1').serialize()  ==> "ANYNAME=test+value" 

c# | WebBrowser control - programmatically select item on html `select`

Hi There,

As many times, we need to interact with the C# (.Net) Webbrowser Control, 

it is useful to be able to interact and programmatically change the selected item 

on an HTML select control.

I don't know, why it is hard to find this easy solution, but the code is as follow:

HtmlElementCollection col = webBrowser1.Document.GetElementsByTagName("select") 
foreach (HtmlElement heItem in col) 
{ 
  if (heItem.GetAttribute("className").Contains("exampleClassName") == true) 
  { 
    heItem.SetAttribute("selectedIndex", "3"); // select value at #3
    break; // incase of needed... 
  } 
}  

And finally, just easy as u code...


If you need change by value and not by index,
I assume you can check the values of the select control (sometimes called: dropdown),
and once you find the correct index of the desired value,
use the code above.
