The fundamental differences between "GET" and "POST" The HTML specifications technically define the difference between "GET" and "POST" so that former means that form data is to be encoded (by a browser) into a URL while the latter means that the form data is to appear within a message body. But the specifications also give the usage recommendation that the "GET" method should be used when the form processing is "idempotent", and in those cases only. As a simplification, we might say that "GET" is basically for just getting (retrieving) data whereas "POST" may involve anything, like storing or updating data, or ordering a product, or sending E-mail. The HTML 2.0 specification says, in section Form Submission (and the HTML 4.0 specification repeats this with minor stylistic changes): If the processing of a form is idempotent (i.e. it has no lasting observable effect on the state of the world), then the f

Few days ago, I was recalling my Java script skill. I was generating Grid using java script script. Instead of using Display property (’none’ or ‘block’) to show or hide the control, I was creating and removing element each time. Creating element is not a big deal. However the script for removing element is different in IE and Firefox . In IE, we can remove the element using, however this will not work in Firefox . document.getElementById(“ControlID”).removeNode(true); In Firefox , you have to use, var Node1 = document. getElementById (“ ParentControlID ”); Node1.removeChild(Node1.childNodes[0]); Below is the sample code for the same. var Node1 = document. getElementById (“Parent”); var len = Node1.childNodes.length; for(var i = 0; i <> { if(Node1.childNodes[i].id == “Child”) { Node1.removeChild(Node1.childNodes[i]); } } Happy Programming !
