Hi everybody,

I need to get a element create dynamically by its name. It's ok for
FF, but on IE, getElementsByName return "undefined".
I create this code but not sure that it can work on older IE ....if
someone can test this code on older IE ?
( and in the hope that it can be usefull for others ! )

1- It first create a combobox dynamically and set the NAME attribute
to it.
2- It overwrite the getElementsByName method if the nav is IE
3- If all is ok, it must write the innerHTML code in an alert box

thanks for help,
TSalm

=====Test.html====

<html>
<head></head>
<body></body>
<script language="javascript">

// <<< BEGIN INSERT

var values = new Array("a","b","c");

    var inputElementName = "SELECT";
    var input = document.createElement(inputElementName);

    input.setAttribute('name', "test.test[0]");

    for (i=0;i<values.length; i++) {
    var option = document.createElement("OPTION");
    option.setAttribute("value", values[i]);
    option.innerHTML = values[i];
    input.appendChild(option);
    }

    document.body.appendChild(input);
// END >>>

// <<<
function findElByName(nd,strName) {

    for (i=0;i<nd.childNodes.length;++i) {

// find it ?
if (nd.childNodes[i].name==strName) {
return nd.childNodes[i];
        }

        // childNode ?
        if ((nd.childNodes[i].hasChildNodes()) && (nd.childNodes[i].tagName !
= "OPTION")) {
        val = findEl(nd.childNodes[i],strName);
        if (val) return val;
        }
}

return null;

}

if (navigator.appName == "Microsoft Internet Explorer") {
document.getElementsByName = function(str) {
o = findElByName(document.body,str);
if (o) {
return new Array(o);
}
return undefined;
}
}
// >>>

alert(document.getElementsByName("test.test[0]")[0].innerHTML);

</script>

Are you kidding? Trying to find an IE5.5 user is hard enough, much less
an IE5 user.
