im having a set of multiple check bxes, like one set contain 3 check box share same name another set contain 3 check sharing same name . how can i get the value of these two different set of check box using a single code .
var form = $('usersurvey');
checkboxes = form.getInputs('checkbox');
for(count=0; count< checkboxes.length; count++){
if(checkboxes[count].checked){
retValue=true;
break;
}
}
return retValue;
}
im tried with this code but it fetch all the check boxes , i want only that have the same name, i used prototype.js
if you give each set of checkboxes a different class you could select them using jquery like:
$(".className").each(function(index, element) { ... });
for instance. somebody may be able to improve on this solution by selecting by name (i wasnt sure if you could do that, i always just select by class).
EDIT: sorry i should elaborate probably. the $(".className") piece will select all the checkboxes of class 'className'. since it sounds like you want to DO something with each of them though, i just added the each call on the end. inside the each call, you can define a function (shown) that will do something for each checkbox that was selected. reference the jquery each docs here:

I have a drop-down menu in a form with elements retrieved from a database. Something like this :
for($i=0;$i<count($resq);$i++){
print("<li><a class=\"dropdown-item\" href=\"#\" id=\"$i\">{$resq[$i][0]}</a></li>");
}
$resq being an array containing the result of the query (i used mysqli_fetch_all).
As you can see I tried to dynamically generate the id of the items(first item has id=0, second has id=1 and so on till the final value of $i) but I think this is not correct.
Previously, I had the following JS code(which worked) which I used to set the drop-down value to the one selected by the user and to set the value of a hidden input to that value.(I know the code isn't elegant but I just wanted to test the logic in the first place)
var x=document.getElementById('dropdownMenuButton1slct');//dropdown
var c1=document.getElementById("0");//i - categories(IDs of the dropdown elements)
var c2=document.getElementById('1');
var c3=document.getElementById('2');
var c4=document.getElementById('3');
var c5=document.getElementById('4');
var p=document.getElementById('iaval');//hidden input from form
function clic(z){
z.onclick=function () {
x.innerHTML=z.innerHTML;
p.value=x.innerHTML;
};
}
clic(c1);
clic(c2);
clic(c3);
clic(c4);
clic(c5);
But now the same method won't work. If you can, please suggest me a different way or something, I am kinda stuck. I can provide more info if this seems vague or something like that. Thanks.
I currently have a form that is displaying fields that I do not want it to. There are 3 input fields associated with one form and the same form is being rendered multiple times.
I have my template set up to check for when this was only one value. I need to change it so the template will check for all of the values present & then decide to render.
So for example,
I have,
Div_id_form-0-x,
Div_id_form-0-y,
Div_id_form-0-z,
Div_id_form-0-location__location_category__requires_coordinates
What selector can I use to grab all of these to use in my template?
I need to grab them for each form. Where it says form-0 I have several of these forms repeating.
Then in HTML I have something like this.
$(function () {
// Determine weather we are in a modal window.
var context = $("#{{ contextId }}-form");
console.log("this is the {{ contextId }}" )
// Show required coordinates if location category requires them.
context.find("#id_location__location_category__requires_coordinates").change(function () {
if (context.find("#id_location__location_category__requires_coordinates").val() == 'Y') {
context.find('#id_needs_coordinates').removeClass('hide');
} else {
context.find('#id_needs_coordinates').addClass('hide');
}
});
});
Right now this is only checking for one value to determine whether to hide. I need it to check all of these for this value. Which is why I'm looking for a Jquery selector that can do such.
If you want a selector for IDs, you can use:
$("#Div_id_form-0-x, #Div_id_form-0-y, #Div_id_form-0-z, #Div_id_form-0-location__location_category__requires_coordinates")
Please see: https://api.jquery.com/id-selector/
Update
In the future, please clarify the entire issue and provide a proper example.
You can use the Attribute selectors.
$("[id^='Div_id_form-']")
This will select all IDs like:
Div_id_form-0-x
Div_id_form-1-x
Div_id_form-2-x
You will then select all of those elements.

I have a couple of radios (#LocalDelivery and #StandardShip) related to a couple text inputs (#LocalDate and #datepicker). Then, off in another section is another text input with class productAttributeValue.
If LocalDelivery is chosen/checked, I need its input, #LocalDate to get the value and name from the input with class productAttributeValue. Or, if #StandardShip is chosen/checked I need its input, #datepicker, to get the value and name from the input with class productAttributeValue.
I have tried various combinations of the following:
if (!$('#LocalDelivery').is(":checked")) {
$('#datepicker').val("");
$('#LocalDate').val($('.productAttributeConfigurableEntryText div.productAttributeValue input[type="text"]').val());
$('#LocalDate').attr('name',
$('.productAttributeConfigurableEntryText div.productAttributeValue input[type="text"]').attr('name'));
}
if (!$('#StandardShip').is(":checked")) {
$('#LocalDate').val("");
$('#datepicker').val($('.productAttributeConfigurableEntryText div.productAttributeValue input[type="text"]').val());
$('#datepicker').attr('name',
$('.productAttributeConfigurableEntryText div.productAttributeValue input[type="text"]').attr('name'));
}
Per my other thread, Issue with jQuery 'else', this method isn't working. According to the answers given there, this is the wrong method entirely but I'm not sure how else to go about this.
Here is a fiddle:
This is my glorious Fiddle
EDIT:
Per beautifulcoder's comment I have added a click function to both radios. While it would be preferable for the inputs to populate their value without clicking first, this is the first solution I've had that works. Created a fiddle here, hope it helps someone else:

I am dynamically generating some dropdowns and then allowing them some of those to be removed on board dyanmically. so that time, i have encountered an error of selection option (dropdown) elements id mismatch. something like below is.
newly added dropdowns.
select name="CSSAtapsClient[client_time_window_arr][0]" id="client_time_window_0">/select>
select name="CSSAtapsClient[client_time_window_arr][1]" id="client_time_window_1">/select>
select name="CSSAtapsClient[client_time_window_arr][2]" id="client_time_window_2">/select>
select name="CSSAtapsClient[client_time_window_arr][3]" id="client_time_window_3">/select>
after i dynamically remove them via javascript. (lets say i am removing the second one) so then new ones will be displayed as followings,
select name="CSSAtapsClient[client_time_window_arr][0]" id="client_time_window_0">/select>
select name="CSSAtapsClient[client_time_window_arr][2]" id="client_time_window_2">/select>
select name="CSSAtapsClient[client_time_window_arr][3]" id="client_time_window_3">/select>
So now the issue i have is, the names of the dropdowns are like this, (0,2,3)
CSSAtapsClient[client_time_window_arr][0],
CSSAtapsClient[client_time_window_arr][2],
CSSAtapsClient[client_time_window_arr][3]
So this is causing an error for me and i need to reorder this name and make it be like this, (0,1,2)
CSSAtapsClient[client_time_window_arr][0]
CSSAtapsClient[client_time_window_arr][1]
CSSAtapsClient[client_time_window_arr][2]
how can i simply rename these dropdowns name attribute (from 0 to how much ever dropdows are exisiting) ? appreciate an early reply
EDIT 1
I tried this, but didnt work.
$('#tbl_dynamic_call_dates select').each(function(i){
$(this).attr('name',"CSSAtapsClient[client_time_window_arr][i]");
});
You can simply reset the values using .attr() method:
$('#tbl_dynamic_call_dates select').attr('name', function(i) {
return 'CSSAtapsClient[client_time_window_arr]['+ i +']';
});
I did this,
$('#tbl_dynamic_call_dates select').each(function(i){
$(this).attr('name',"CSSAtapsClient[client_time_window_arr][" + i + "]");
});
I have 50 rows of data and i want users to give them points by 1 to 50. I put dropdown boxes near them with options 1/50. But all i want is when a user selects 15(for example) for a row, 15 will be deleted from all other select tags of other rows. I am not as good as you in JavaScript. How can i accomplish this?
Hi casablanca i couldnt make he script you sent work. I need it to work on just one select tag so i give select tag an ID and an ID for the form too. I edit the scripts getElementsByTagName with getElementsByTagID (select tag's ID) to effect only one select tag. But the function doesnt triggered?
This might not be a very good idea, because it is very difficult for the user to modify choices -- for example, if I want to give 15 to a different option, I need to change the old one to something else and then change the new one to 15. Also, once all points have been assigned, it's impossible to make any changes because all options are gone.
A better idea would be to let the user do whatever he/she wants and then validate the form in the end. You could do that like this:
function validate() {
var used = []; // This array stores already used options
var rows = document.getElementById('myForm').getElementsByTagName('select');
for (var i = 0; i < rows.length; i++) {
var points = rows[i].value;
if (used[points]) {
// This value was already used
alert('Please choose a different value.');
rows[i].focus();
return false;
} else {
// This value was not used before; mark it as used now
used[points] = true;
}
}
return true;
}
And call this function in the onsubmit handler of your form:
<form id="myForm" onsubmit="return validate();">
EDIT1: id -> class
give each option the class of the number it is
<option class="15">15</option>
<option class="16">16</option>
etc.
Then jquery can remove() an item by class
$('.15').remove();
obviously have to do an on change and get the value just set. "remove()" is nice in this instance because I believe it will yank every instance of that class.
EDIT3: upon further consideration the above method would be further complicated by the need to not remove the "selected" option. Not going to figure out the exact method but I think changing the class from "15" to "selected15" with a $(this).append() or something of the sort before calling the remove would get the job done fairly safely.
EDIT2:
As noted by casblanca below this is not an ideal user interface at all for this type of input. You may want to look into this: http://www.utdallas.edu/~jrb048000/ListReorder/
Allows user to drag and drop items in a list to reorder them. Much more natural.
