Question

I know there are many other threads on this but i can't seem to make heads or tails of them and make them work in my code. I have multiple dropdowns on a page with a yes/no answer each question has sub questions if yes is chosen.. I would like to have the sub questions only display if yes is chosen from the primary question. that way i can clean up the page and get red of the if yes then this verbage.

Any help would be appreciated on the best way to do this :)

AleMonteiro 238 Can I pick my title?

11 Years Ago

You have to add an onChange event to the "masters" selects, and when they change you update the require rows.

What is showresults(eReg|HRI_Asthma) suppose to mean?

AleMonteiro 238 Can I pick my title?

The best alternative is to create a function to hide/show rows, something like this:

function toggleRows(select, rows) {

    var display = select.selectedIndex == 1 ? '' : 'none';

    for(var i=0; i < rows.length; i++) {
        document.getElementById(rows[i]).style.display = display;
    }

};

And you should use as:

<select onchange="JavaScript: toggleRows(this, ['testing1', 'testing2', 'testing3']);">

So i tried that and it didn't work. Although I am sure I did something wrong as I am not too good at this

<tr class="~[evenoddrow]"> 
            <td class="bold">ASTHMA:</td><td id="HRI_Asthma">~([01]HRI_Asthma)</td><td class="gwCen"></td>
            <td><select name="eReg|HRI_Asthma" onchange="if (this.selectedIndex=='1'){this.form['asthmameds'].style.visibility='visible'}else {this.form['eReg|HRI_Asthma_Meds'].style.visibility='hidden'};">
            <option value="" selected="selected"></option>
            <option value="Yes">Yes</option>
            <option value="No">No</option>
</tr>
<tr class="~[evenoddrow]" name="asthmameds"> 
            <td class="bold"><span style="padding: 0 80px">If yes list medication to be given at school:</span></td><td id="HRI_Asthma_Meds">~([01]HRI_Asthma_Meds)</td><td class="gwCen"></td>
            <td><input type="text" name="eReg|HRI_Asthma_Meds" id="eReg|HRI_Asthma_Meds" value="" size="30" /><span class="gwExample">medication1, medication2,</span></td>
</tr>

Doing it this way don't work it won't hide anything

Below works if i want to hide only the text box

<tr class="~[evenoddrow]"> 
            <td class="bold">ASTHMA:</td><td id="HRI_Asthma">~([01]HRI_Asthma)</td><td class="gwCen"></td>
            <td><select name="eReg|HRI_Asthma" onchange="if (this.selectedIndex=='1'){this.form['eReg|HRI_Asthma_Meds'].style.visibility='visible'}else {this.form['eReg|HRI_Asthma_Meds'].style.visibility='hidden'};">
            <option value="" selected="selected"></option>
            <option value="Yes">Yes</option>
            <option value="No">No</option>
</tr>
<tr class="~[evenoddrow]" name="asthmameds"> 
            <td class="bold"><span style="padding: 0 80px">If yes list medication to be given at school:</span></td><td id="HRI_Asthma_Meds">~([01]HRI_Asthma_Meds)</td><td class="gwCen"></td>
            <td><input type="text" name="eReg|HRI_Asthma_Meds" id="eReg|HRI_Asthma_Meds" value="" size="30" /><span class="gwExample">medication1, medication2,</span></td>
</tr>

My goal here is to hide the complete row not just the data within the row. I can't seem to figure it out

rpgowned 0 Newbie Poster · Answer 2 · 2012-12-19T20:16:34+00:00

I was thinking i could do something like the following..

<script type="text/javascript" language="javascript">        
    function showresults(SiteValue) {
if (eReg|HRI_Asthma == 'Yes') {
document.getElementById('asthmameds').style.display='';
}
else {
document.getElementById('asthmameds').style.display='none';
}
}



<tr class="~[evenoddrow]"> 
            <td class="bold">ASTHMA:</td><td id="HRI_Asthma">~([01]HRI_Asthma)</td><td class="gwCen"></td>
            <td><select name="eReg|HRI_Asthma" id="eReg|HRI_Asthma">
                    <option></option><option value="Y">Yes</option><option value="N">No</option>
</tr>
<tr class="~[evenoddrow]" id="asthmameds"> 
            <td class="bold"><span style="padding: 0 80px">If yes list medication to be given at school:</span></td><td id="HRI_Asthma_Meds">~([01]HRI_Asthma_Meds)</td><td class="gwCen"></td>
            <td><input type="text" name="eReg|HRI_Asthma_Meds" id="eReg|HRI_Asthma_Meds" value="" size="30" /><span class="gwExample">medication1, medication2,</span></td>
</tr>

But That don't seem to work either :(

I made some mistakes above so I tried to fix them here.. but it is still not working.

  <script type="text/javascript" language="javascript">      
    function showresults(eReg|HRI_Asthma) {
if (eReg|HRI_Asthma == "Yes") {
document.getElementById('asthmameds').style.display='';
}
else {
document.getElementById('asthmameds').style.display='none';
}
}
</script>
<tr class="~[evenoddrow]"> 
            <td class="bold">ASTHMA:</td><td id="HRI_Asthma">~([01]HRI_Asthma)</td><td class="gwCen"></td>
            <td><select name="eReg|HRI_Asthma" id="eReg|HRI_Asthma" onchange="showresults(this.value)">
                    <option value=""></option><option value="Yes">Yes</option><option value="No">No</option>
</tr>
<tr class="~[evenoddrow]" id='asthmameds'> 
            <td class="bold"><span style="padding: 0 80px">If yes list medication to be given at school:</span></td><td id="HRI_Asthma_Meds">~([01]HRI_Asthma_Meds)</td><td class="gwCen"></td>
            <td><input type="text" name="eReg|HRI_Asthma_Meds" id="eReg|HRI_Asthma_Meds" value="" size="30" /><span class="gwExample">medication1, medication2,</span></td>
</tr>

To be completely honest I don't really know what I am doing lol.. basically I am playing with scripts i have found trying to get something to work..

The thing i don't understand is i can use something like

<tr class="~[evenoddrow]">
    <td class="bold">ASTHMA:</td><td id="HRI_Asthma">~([01]HRI_Asthma)</td><td class="gwCen"></td>
    <td><select name="eReg|HRI_Asthma" onchange="if (this.selectedIndex=='1'){this.form['eReg|HRI_Asthma_Meds'].style.display=''}else {this.form['eReg|HRI_Asthma_Medss'].style.display='none'};">
    <option value="" selected="selected"></option>
    <option value="Yes">Yes</option>
    <option value="No">No</option>
    </tr>
    <tr class="~[evenoddrow]" id="testing">
    <td class="bold"><span style="padding: 0 80px">If yes list medication to be given at school:</span></td><td id="HRI_Asthma_Meds">~([01]HRI_Asthma_Meds)</td><td class="gwCen"></td>
    <td><input type="text" name="eReg|HRI_Asthma_Meds" id="eReg|HRI_Asthma_Meds" value="" size="30" /><span class="gwExample">medication1, medication2,</span></td>
    </tr>just yes/no

and it hides the text box just fine

but if i change

{this.form['eReg|HRI_Asthma_Meds'].style.display=''}else {this.form['eReg|HRI_Asthma_Meds'].style.display='none'};">

to

    {this.form['testing'].style.display=''}else {this.form['testing'].style.display='none'};">

in order to have it hide the whole table row it does nothing

AleMonteiro 238 Can I pick my title? · Answer 5 · 2012-12-20T14:50:40+00:00

Try this:

{document.getElementById('testing').style.display=''}else {document.getElementById('testing').style.display='none'};

The difference is like this: this.form['element_name'] and document.getElementById('element_id')

I have a curiosity question for you, what server-side language are you using?

rpgowned 0 Newbie Poster · Answer 6 · 2012-12-20T16:30:40+00:00

this is for PowerSchool student information system which is java based at its core there is also a custom PowerSchool language in conjunction.

and that worked wonderfully :) thank you so much

one more question if i had another TR say testing2 how would i add that to

    {document.getElementById('testing').style.display=''}else {document.getElementById('testing').style.display='none'};

in order to hide both rows some of the options have 5-6 rows associated with them

rpgowned 0 Newbie Poster · Answer 7 · 2012-12-20T18:16:36+00:00

That is exactly what I needed thank you so much appreciate all your help
