jquery form BASIC validation question -

-

I am trying to validate a form if there is no text in the input field, an error icon pops up it happens .. . And if anything is in input then a successful icon pops up. There are no true verification methods being used. You can see the form.

As you can see, when you type something in the first field and you press the tab, the icon is decided correctly, but it will not work on any field after the first. Here's my junkie: 

  & lt; Script type = "text / javascript" & gt; $ (Function () {var field = document.getElementById ('myFormField'); var icon = document.getElementById ('myIcon'); field.onchange = function () {icon.src = this.value? 'Success.png ':' Fail.png ';};}); & Lt; / Script & gt;

I do not know how it works on all input fields, but I'm sure it's a simple fix. My HTML is set to: 

  & lt; Input type = "text" class = "name" name = "name" tabindex = "1" id = "myFormField" /> & Lt; Img id = "myIcon" />

id triggers the icon myFormfield, and the class triggers the background of the "name" click. I think I should stay with the class and try to use it as a part of this solution. Any ideas?

Try to do something that you are not actually using the power of jQuery: 

  $ (function () {$ (': text,: textarea'). Bind ('change, blurring', function () {$ (this) .next ('IMG'). Et ('src', this.value? 'Success.png': 'fail.png');});});

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
