Check if Checkbox is checked based on name

Question

This is my code and it always returns "nothing is checked" no matter if something is checked or not.

function rstSelfs() {
var chkds = document.getElementsByName('selfs');
if(chkds.checked)  {
alert ("something is checked"); }
 else {
alert("nothing is checked");
}}

I have been using the above as a test to see if I can get the code to work properly. I have multiple checkboxes with the name "selfs" and I want the dropdown selection only to reset if none of the boxes with the name "selfs" are not checked. I would assume the code would look like this but nor this or the code above works... Please help.. I new to this and I have attempted to search and it is possible this has been answered but I apologize it did not name sent to me.

What I want the code to do is this:

function rstSelfs() {
var chkds = document.getElementsByName('selfs');
if(chkds.checked)  {
return false;  }
 else {
($('.CssSel').get(0).selectedIndex = 0) }
}



<form id="Service">
   <input type="checkbox" name="site" id="cktmcom" onclick="isTsite()">

    <input type="checkbox" name="selfs" id="ckselfc" onclick="isTsserv();isTextServC()">
    <label for="checkbox">Self-Serve Classic</label><br>
    <input type="checkbox" name="selfs" id="ckselfn" onclick="isTsserv();isTextServN()">
    <label for="checkbox">Self-Serve Next-Gen</label><br>
    <input type="checkbox" name="homeSer" id="ckhomes" onclick="isThs()">
    <label for="checkbox">Home Services</label><br>
    <input type="checkbox" name="mapp" id="ckmobilea" onclick="isTmApp()">
    <label for="checkbox">Mobile App</label><br>
    <input type="checkbox" name="checkbox" id="ckgem" onclick="isTextGem()">
    <label for="checkbox">Gemini</label><br>
</form>

<form id="Service2">
    <input type="checkbox" name="site" id="ckkmcom" onclick="isKsite()">
    <label for="checkbox">mobile.com</label><br>
    <input type="checkbox" name="selfs" id="ckKselfc" onClick="isKsserv();isKServC()">
    <label for="checkbox">M Self-Serve Classic</label><br>
    <input type="checkbox" name="selfs" id="ckKselfn" onClick="isKsserv();isKServN()">
    <label for="checkbox">M Self-Serve Next-Gen</label><br>
    <input type="checkbox" name="mapp" id="ckKmobilea" onclick="isKmApp()">
    <label for="checkbox">M Mobile App</label><br>
</form>

The checkboxes with name "selfs" control the hide and show for the div = selfserve. And I need to reset the drop down selection only if none of the "selfs" are chcked . I have actually have 5 checkboxes that have the name selfs. The code is rather large thats why the other 3 are missing.

The HTML dropdown code is:

<div id="selfserve" style="display:none">
<select class="CssSel" style="width:175px" onChange="ssPicker()">
<option value="1" selected  style="color:red;" ssSel="**Self-Serve Issue**">Select Self-Serve        
Issue</option>
<option value="2" ssSel="Entire Site Down">Entire Site Down</option>
<option value="3" ssSel="Login Issues">Login Issues</option>
<option value="4" ssSel="Usage Meter Issue">Usage Meter Issue</option>
<option value="5" ssSel="Change feature Issues">Change feature Issues</option>
<option value="6" ssSel="Page Loading Issues">Page Loading Issues</option>
<option value="7" ssSel="Extreme Latency">Extreme Latency</option>
<option value="8" ssSel="Navigation Issues">Navigation Issues</option> 
</select>


</div>
 <input type="button" name="reset_self" value="Reset" onClick="rstSelfs()">

Solution 1

Not working:

Since you use jQuery, you can check if any checkboxes are not checked:

function rstSelfs() {
    var chkds = $("input[name='selfs']:checkbox");

    if (chks.not(":checked").length > 0)  {
        return false;  
    } else {
        ($('.CssSel').get(0).selectedIndex = 0) 
    }
}

this worked but I had to rework it a bit! thank you!

Tweaked, working:

function rstSelfs() {
var chkds = $("input[name='selfs']:checkbox");

if (chkds.is(":checked"))  {
    return false;  
} else {
    ($('.CssSel').get(0).selectedIndex = 0) 
}
}

Solution 2

getElementsByName() function returns an array of elements, not single element, so it doesn't have property checked. If there is only one element by this name you should use something like this:

document.getElementsByName("selfs")[0].checked

Or to correct your function:

function rstSelfs() {
   var chkds = document.getElementsByName('selfs')[0];
   if(chkds.checked)  {
       alert ("something is checked"); }
   else {
       alert("nothing is checked");
}}

I attempted to use this but did not work. I corrected the error with the var name as in the if statement it is written as chks rather than chkds.

[user3837156]

I do have multiple elements with that name so how would I go about checking?

Uncaught TypeError: Cannot read property 'selfs' of undefined for (i=0; i<document.telusService.selfs.length;i++) {

[Jitesh]

what is telusService - I do not see that in your HTML code. Maybe try this in for loop :- document.getElementById("id_of_form_which_contains_selfs").s‌​elfs.length instead of document.Service.selfs.length .

[user3837156]

sorry I renamed it in my code but i did use <document.Service.length... but I also assume this code when it works will only reset it for the form named Service but will not reset it for the form that is named Service2

[user3837156]

i changed it to document.getelementbyid and it just resets the dropdown regardless if something is checked or not.

Anyone know why this code doesn't work? This makes the most sense to me but does nothing
