Check out "GetById()" in the page below.
There are limitations, of course. GetById() is not case-sensitive, meaning "ixv[list]" will be treated the same as "Ixv[List]", and spaces in the id are significant, meaning that "ixv[list]" is different from "ixv [list]"
This solution works in IE, Firefox, Chrome, Safari, and Opera.

return a [i];
}

var x=GetById("INPUT","ixv[list]",num).value;
alert(x);

I have a form for which I cannot change the input value field names. One such field is in the HTML as follows:--<body> <form id="f" method="get" action="/code/submit.php"> <input type="text" name="var[list]" id="ixv[list]" value=""> <button type="button" title="Save" onclick="check();"> </form> </body>Now in my javascript, I want to access that input value. I tried this, and of course it doesn't work since [] looks like an array in JS.
function check() { var x=var[list].value; alert(x); }The problem is that the variable name has [] in it. How can I get that input field value in javascript?
