    Post Is it possible to assign values to document.getElementsByName('field')

    I have to update the rowid(assigned to checkbox) whenever the textbox value is updated and this needs updating value of document.getElementsByName('rf_select[]') when checkbox value matches the textbox id. There can be mutliple number of rows each with a uniqueID (checkbox value) that matches with the textboxID onload.

    Code :-

    <td align="center"><input type='checkbox' name='rf_select[]' id='rf_select' value="rowId" CHECKED border="none"/>
    <td align="left"><input type='text' name='policy_no' id="rowId" size='25' value="test" onBlur=handleRowId('policy_no'); /></td>

    <script language="javascript">
    function handleRowId(){
    var arr = new Array();
    var rowarr = new Array();
    arr = document.getElementsByName('policy_no');
    rowarr = document.getElementsByName('rf_select[]');
    for(var i = 0; i < arr.length; i++)
    var obj = arr.item(i); //alert(obj.id + " = " + obj.value);
    for(var j=0; j< rowarr.length; j++){
    if(rowarr[j].value == obj.id){
    document.getElementsByName('rf_select')[j].value = rowarr[j].value+"#@#"+obj.value;

    I am having problem assigning values here - document.getElementsByName('rf_select')[j].value = rowarr[j].value+"#@#"+obj.value;

    Any help is appreciated.

    You do NOT have any fields on that page named "rf_select".

    That may be the name in PHP, but in the browser their name really and truly *IS* "rf_select[]".

    The browser's DOM doesn't treat the "[]" in the name special the way PHP does.
