I am trying to create function that will look at the username if it is not valid send an alert to the user, clear the username field, and put the username field back into focus. I am trying to do this all with the getElementsBynName() function. It is all working with the exception of getting the field back into focus. My code is below. Does anyone have any suggestions. function uchecker(uname) { var validUname = uname.search(/^\w+@sabc.com$/); if(validUname != 0) { alert("You have entered an invalid username. \n The username must be a valid @sju.edu email address value " + document

GetElementsByName with array like name

i often use this notation when i name my controls in order to get an array in POST or GET. <input name="color[1]" type="text" /> <input name="color[2]" type="text" /> <input name="color[3]" type="text" /> so in my scripts i can do <?php $data=$_GET["color"]; for each ($color as $key=>$value) { doSomething(); } ?> Often happens that i need to get those id back in javascript , but i cannot get them , so i often add an ID to each element in html like that <input name="color[3]" id="color_3" type="text" /> so that i can use document.getElementsById('color_3') Instead i would like to find way to

On IE document.getElementsByName won't work

I use this code: <div name="1234"> <img src="pic.gif" height="70" width="100" onMouseOver="clear('1234')"> </div> And: function clear(element_name){ document.getElementsByName(element_name)[0].innerHTML=""; } It does work in Firefox and Opera, but doesn't work in IE 6.0 or IE 8.0, and probably not even in newer IE's. What to do? Well, the problem is this: IE understands document.getElementsByName(...)[0] as document.getElementById(...). So if you would define also an id for your element, the method document.getElementsByName(element_name)[0].innerHTML="" will surprisingly also work in IE! But

Javascript: setAttribute() v.s. element.attribute = value to set “name” attribute

So I'm learning to manipulate the DOM and I noticed one interesting thing: Let's say I want to set the name attribute of an element by using the "." dot notation: element.name = "someName"; console.log(document.getElementsByName("someName")[0]); // returns "undefined"?? However if I use the document.setAttribute() method, it works fine: element.setAttribute("name", "someName"); console.log(document.getElementsByName("someName")[0]); // returns the element like it should. Not sure why the dot notation method doesn't work in the first case. Why does this happen? My guess (because you didn't

I have a struct definition with about 25 elements struct X { field 1; field 2; .. }; and I'm trying to fill it with some map values Map<String,String> A and it appears to be very annoying to do such thing n times X->xx = A["aaa"] every time that I want to fill my message struct. Is it possible to access the members by name, e.g. X->get_instance_of("xx").set(A["aaa"]); and put it into a loop? C++ lacks built-in reflection capabilities of more dynamic languages, so you cannot do what you would like using he out of the box capabilities of the language. However, if all members are of the same type
