Problem storing value in textbox array

JavaScript
1

Please can someone assist me with the solution to this problem. I need to store the result of the hdvest array. What is wrong with my code.

function getval() {
    var e = document.getElementsByName("investresult[]");
    for(var i = 0; i < e.length; i++) {
      var f = e[i];
      alert(f.value);
      document.getElementByName("hdinvest[i]").value = f.value;
    }
}

There’s an ‘s’ missing from the second use of document.getElementsByName()

Also, to get your code formatting to work, you can either highlight it and click on the </> icon on the editor toolbar, or use three backticks ( ``` ) on the line before and the line after your code.

The problem is yet to be resolved

you have no element with the name hdinvest[i].

5

What HTML are you applying this JS to? Can you post the relevant content here so we can make better sense of what should be happening.

6

i do have element bearing that name

7

Does the alert show what you expect it to?

A NodeList (as returned by getElementsByName()) doesn’t have a value property, and assigning one won’t have any effect per se. Did you mean something like

document.getElementsByName("hdinvest[]")[i].value = f.value;

Note that naming input elements with square brackets doesn’t have any effect on the JS, it only makes PHP recognise them as an array within the action script.

            <SELECT class="form-control invest" name="invest[]" id="invest[]" >
                <OPTION value="">Select Investigation</OPTION>
                <?php 
                $query2="select laboption,fee from investigation group by laboption order by laboption asc";
                $resultquery2=mysql_query($query2) or die(mysql_error());
                while($row2=mysql_fetch_array($resultquery2)){
                extract($row2);
                ?>
                <OPTION value="<?php echo $fee;?>"><?php echo $laboption;?></OPTION>
                <?php }?>
                
            </SELECT>
   <INPUT class="form-control" type="text" name="investresult[]" id="investresult[]" placeholder="Investigation Result" onchange="getval();"/>

Can you do a rendered version of the resulting HTML from that? I don’t think anyone is going to try interpreting your PHP to work out what HTML comes out of it, and then has some JS applied to it.
