JavaScript - Only Submit If At Least One Checkbox Is Checked (dynamically)
Hi,
Have searched the forum and found a soloution that probably only needs some modification. I have a number of question with related alternatives in a db that I display on a webpage. I wan't to force the user to select an alternative. I use checkboxes because sometimes more then one answer is correct. I have found a bit of code that lets me do this. The problem is that sometimes the alterative to the question is 3 and sometimes 5 (I don't know beforehand how many alterantives a question has). So is there a way to modify the code to work if there are 3 checkboxes or 5 checkboxes and so on...? The code below only works with a fixed number of alternatives. Code: <form action="../" onsubmit="return checkCheckBoxes(this);"> <p><input type="CHECKBOX" name="CHECKBOX_1" value="This..."> This...</p> <p><input type="CHECKBOX" name="CHECKBOX_2" value="That..."> That...</p> <p><input type="CHECKBOX" name="CHECKBOX_3" value="...and The Other"> ...and The Other</p> <p><input type="SUBMIT" value="Submit!"></p> </form> Code: <script type="text/javascript" language="JavaScript">
<!--
function checkCheckBoxes(theForm) {
if (
theForm.CHECKBOX_1.checked == false &&
theForm.CHECKBOX_2.checked == false &&
theForm.CHECKBOX_3.checked == false)
{
alert ('You didn\'t choose any of the checkboxes!');
return false;
} else {
return true;
}
}
//-->
</script>

Is it possible to send a checkbox value to the DB when checked and or unchecked. I mean when you Physically chage it's state. I am running a PHP project, the page I need this functionality on has a dynamically built table from the Database. What I need to do is send the value "1" to the DB if I check on one of the rows "Published" checkbox and vice versa, removing the value of 1 from the db and changing the state to unchecked. The reason I ask in the JS forum is that PHP is a server side language and as such may not submit the change in realtime. Any help and or suggestions is much appreciated.

Basically if the checkbox with a class of cf_flt is checked then I want the div '.filterbox' to show. if the checkbox is unchecked then I want it to hide. As well as this I have a toggle button called '.filtertoggle' which toggles the '.filterbox' At the moment the '.filterbox' shows regardless of whether or not the checkbox is checked. The toggle button works correctly. If you know how to fix this then I would be very grateful. Thank you. hello I have a list of checkbox called de[] i use [] for create array in php so i have a button called "delete" so i want to activate the button if almost one of checkbox has been checked other way the input button will be disable. sorry for my english jejejeje.

Thanks. ok so here is my situation i have 4 hidden fields in a form called "searchform" Code: <input type="hidden" name="forumchoice[]" value="1" checked /> <input type="hidden" name="forumchoice[]" value="2" checked /> <input type="hidden" name="forumchoice[]" value="3" checked /> <input type="hidden" name="forumchoice[]" value="4" checked /> Now here's what i want to do: i have two checkbox Code: <input onclick="??????????" type="checkbox" name="checkbox1" id="checkbox1"/> <input onclick="??????????" type="checkbox" name="checkbox2" id="checkbox2"/> - when checkbox1 is checked, i want to activate the hidden inputs 1 & 2. if it is unchecked, then desactivate hidden inputs 1&2 - when checkbox2 is checked, i want to activate the hidden inputs 3 & 4. if it is unchecked, then desactivate hidden inputs 3&4 could someone help me with the "onclick" code i would need to do this ?? thanks a lot!! I was wondering if anyone could help me with getting this working. I'm using html to create a table which has at least 1 row but no max number of rows - as they can be added/removed by the user - and 4 columns, 1st contains a checkbox and the last 2 contain drop down menus. I wish to be able to store the values of those menus in an array only if that row's checkbox has been checked. e.g if the first row has 1 and A as it's dropdown values and the second row has 2 and B. If only row 1 has been checked the array should only contain [1,A]. Instead mine holds all the values including the non-checked ones i.e [1,A,2,B]. My code for javascript function and html table are below: Code: function calculate(textID){
var table = document.getElementById('course'); //id of table
var rowCount = table.rows.length;
var array = []; //array to hold the values
var c = 0;
dmenus = document.getElementByTagName("select"); //get the drop down menus
for(var a = 1; a < rowCount; i++){ //a = 1 as the 1st row contains column headings
var row = table.rows[a];
var check = row.cells[0].childNodes[0];
if(null != check && true == check.checked){
for(var b = 0; b < dmenus.length; b++){
val = dmenus[b].options[dmenus[b].selectedIndex].value;
array[c] = val; //set index of array to equal value of dropdown box
c++;
}
}else{
b++;
}
}
Html code for table: Code: <table id="course">
<tr>
<td><input type="checkbox" name="ucheck" id="ucheck" onclick="checkAll('course')"/></td>
<th style="color:white">Course Title</th>
<th style="color:white">Credits</th>
<th style="color:white">Grade</th>
</tr>
<tr>
<td><input type="checkbox" name="tick" id="tick"/></td>
<td><input type="text"/></td>
<td>
<select name="credits" id="credits">
<option...</select></td>
<td>
<select name="grade" id="grade">
<option...</td>
It works only for the first row but if there are more than 1 row it doesn't do what it's supposed to. The coding platform I'm working on does not seem to support jquery so javascript code will be most appreciated. Thanks I need help, please. How would you write javascript code to check (add tick mark) the checkbox in the below code snippet based on a condition? I have tried using the structu if(x) {document.form.name.checked=true;} but it did not work. I think the checkbox name format below, is a problem. This is all done client-side. Anyone know how to do this? Thanks for any help.

If this has been answered before, please direct me to the corrent post. I've created several dynamic checkboxes with with following code: <code> var pnl = document.getElementById("pnlSalesPeople"); for (i = 0; i < sales.length; i++) { var ck = document.createElement("input"); ck.type = "checkbox"; ck.id = "ck" + i; //ck.checked = true; var label = document.createElement('label'); label.htmlFor = ck.id; label.id = "label" + i; label.appendChild(document.createTextNode(sales[i])); pnl.appendChild(ck); pnl.appendChild(label); pnl.appendChild(document.createElement('<br />')); } </code> All the checkboxes get put into the panel, one per line, as expected. However, clicking on any of them does not change their checked state--if I uncomment the line setting the state above, all the checkboxes are checked, but they don't become unchecked when clicking on them. I'm thinking I'm missing something that will make these checkboxes behave like they should or my approach to dynamic creation is flawed. In any event, my knowledge of Javascript is certainly not at expert level so I'm hoping there might a simple solution to my dilemma. Any help on this is genuinely appreciated. TIA Hello, i'm working on a 3 page survey. When hitting next, previous, or submit it passes the values of all the questions to the next page. I've got the whole thing working correcting except for one thing: When the box is "not" checked it passes no value. I'm needing it to have a value of "1" when checked and a value of "0" when not checked, and currently when its not checked and i pass the info it leaves it blank. I'd post the whole code to one of the pages but it's long , so i'll post the snipits of the code. Code: <script type="text/javascript">

The first case that i showed in my code is a radio button, and it passes correctly, i just wanted to show the "format" i was using in a working sense. The 2nd case is an example of the check boxes. Thanks for looking at this, and giving any suggestions you might have! I have a bunch of checkboxes like below that the user can check some or all and click the button and see the values of all the selected checkboxes. How can I do that? Code: <script>
function alertValues(){
}

<input type="checkbox" class ="normal2" value="131977" name="list[]" >
<input type="button" onClick="alertValues()"
