JavaScript getElementByName doesnt work

JavaScript getElementByName doesnt work

Its getElementsByName . Note the plural. It returns an array-like NodeList of elements with that name attribute.

getElementsByName exists, which returns a collection of the elements. If you plan to find only one:

document.getElementsByName(hi)[0].setAttribute(value, my value is high);

Edit: a, HTML there (didnt see that before the edit). No hi element in HTML, possibly in some XML format there is…

JavaScript getElementByName doesnt work

not getElementByName but getElementsByName, and it returns array.

    <script language=javascript>
        function fn() {
            x = document.getElementsByName(hi);
            x[0].setAttribute(value,my value is high);
<body onload=fn()>
    <input type=text id=para />
