i have some checkboxes that are displayed by doing a select in database that represents tables of a restaurant. Those tables that are already reserved i add them an disabled attribute. The problem with my script is that i only want to select three tables max and that means i need to add disabled atribute to the other to block them. and when i want to deselect those 3 already selected i need to remove the disabled attribute. Problem is that it removes the attribute from all tables even those that are reserved and selected from database.
Here is my script:
JSFIDDLE HERE
<script type="text/javascript">
var $checks = $(".table").change(function () {
if ($checks.filter(":checked").length<3)
{
$(".formular").toggle($checks.filter(":checked").length>0);
$checks.not(":checked").removeAttr("disabled");
}
else
{
$checks.not(":checked").attr("disabled", "disabled");
}
});
</script>
Added a class .ignore to the input disabled from start and in js binding change event only to checkboxes without the ignore class as mentioned by #lolka_bolka
HTML
<input type="checkbox" class="bowling ignore" disabled/>
<input type="checkbox" class="bowling ignore" disabled/>
<input type="checkbox" class="bowling"/>
<input type="checkbox" class="bowling"/>
JS
var $checks = $(".bowling:not(.ignore)").change(function () {
if ($checks.filter(":checked").length < 3) {
$(".formular").toggle($checks.filter(":checked").length > 0);
$checks.not(":checked").removeAttr("disabled");
} else {
$checks.not(":checked").attr("disabled", "disabled");
}
});
:not(foo){} will match anything that isn't foo, including html and
body. Source

Below is my code, I am trying to hide and show dynamic elements. The problem I am having is, I only want my hidden div to only show one at a time if only I check "Other". However, the code below will show the hidden div for all number of #dynamicRows I have. so it works for initial 1st #dynamicRow added, the problem is when I have two or more #dynamicRows
$('#dynamicRow').on('click', 'input[id^=race]', function () {
if ($(this).is(":checked")) {
if ($(this).val() == "Other") {
$(".cssclass").each(function (index) {
$(this).closest("div").show();
});
}
else {
$(".cssclass").each(function () {
$(this).closest("div").hide();
});
}
}
});
Below are dynamic rows, for help purposes i am showing the html code, however, it doesn't exist on the screen, a user will click "ADD" to generate the code below. I have no problem in generating dynamic row and it is not why I am posting. note the name in my radio button is generated by c# and everything works. Again the problem is not how to create a dynamic row, it is nicely taken care of in C#.
Dynamic row one works with the above jQuery:
<div id="dynamicRow">
<input type="radio" value="No" id="race[]" name="Person[hhhhhh].race"> No:
<input type="radio" value="Other" id="race[]" name="Person[hhhhhh].race"> Other:
<div id="iamhidden" class="cssclass">
I appear one at a time, when other radio button is checked
</div>
</div>
Dynamic row two doesn't work with the above jquery and it takes the above form events as its own, so if i check the radio button in row 2, the 1st dynamic row responds to that event and vice versa:
<div id="dynamicRow">
<input type="radio" value="No" id="race[]" name="Person[hhhhh].race"> No:
<input type="radio" value="Other" id="race[]" name="Person[hhhhh].race"> Other:
<div id="iamhidden" class="cssclass">
I appear one at a time, when other radio button is checked
</div>
</div>
Working Example
id should be unique in same document, replace the duplicate ones by a class :
<input type="radio" value="No" class="race" name="Person[hhhhhh].race"> No:
<input type="radio" value="Other" class="race" name="Person[hhhhhh].race"> Other:
Also add class and not id to the dynamic rows generated by your C# code :
<div class="dynamicRow">
Then in your js use this class :
$(".cssclass").hide();
$('.dynamicRow').on('click', '.race', function () {
if ($(this).val() == "Other") {
$(this).next(".cssclass").show();
} else {
$(this).nextAll(".cssclass").hide();
}
});
Hope this helps.
Try this:
$('body').on('click', '#dynamicRow', function () {
if ($(this).find('[value=Other]').is(":checked")) {
$(".cssclass").each(function (index) {
$(this).closest("div").show();
});
} else {
$(".cssclass").each(function () {
$(this).closest("div").hide();
});
}
});
He is a working example of what you wanted. I am generating the required with js only.
Few Points to mention
you add the event listener to the parent of the dynamic generated content.
Avoid use of IDs if they are not going to be unique and prefer classes and pseudo selectors if required
var counter = 0;
function addNewEntry(){
++counter;
var str = '<div class="dynamicRow"><input type="radio" value="No" id="race[]" name="Person[hh'+counter+'].race"> No:<input type="radio" value="Other" id="race[]" name="Person[hh'+counter+'].race"> Other:<div id="iamhidden" class="cssclass"> I appear one at a time, when other radio button is checked</div> </div>';
$('#dynamicRowContainer').append(str);
$("#dynamicRowContainer .dynamicRow:last-child .cssclass").hide()
}
$('#dynamicRowContainer').on('change', '.dynamicRow > input', function () {
if(this.value=="Other"){
$(this).siblings('.cssclass').show();
}else{
$(this).siblings('.cssclass').hide();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button onclick="addNewEntry()">Add New Entry</button>
<div id="dynamicRowContainer">
</div>
I want to click on a checkbox and if I click this box it should run a function what gets an ID and saves it into an array or deletes it from the array if it still exists in the array.
That works, but if I click on the text beside the box the function runs twice. It first writes the ID into the array and then deletes it.
I hope you can help me so that I can click on the text and it just runs once
HTML
<label><input type="checkbox" value="XXX" >Active</label>
JavaScript/jQuery
function addOrRemoveBoxes(ID){
if(boxArr.indexOf(ID) != -1){
removeFromArray(ID)
}
else{
boxArr.push(ID);
}
}
$(".checkBoxes").unbind().click(function() {
event.stopPropagation();
addOrRemoveBoxes($(this).find('input').val());
});
The problem is probably that your label and your input are picking the click. Try to bind it only to input. Like this:
$(".checkBoxes input").unbind().click(function() {
event.stopPropagation();
addOrRemoveBoxes($(this).find('input').val());
});
Your HTML is structured bad. When your label is clicked it triggers a click event for the input so you have to separate the input form the label like: <input type="checkbox" name="opt1" id="opt1_1" value="ENG"> <label for="opt1_1">hello</label>. Also your jQuery makes no sense, why do you use unbind()? And we can't see what removeFromArray() does (we can guess but I prefer to see all code used or note that you use pseudo code).
I made this in 5 min: (hopes it helps you)
$(document).ready(function(){
window.boxArr = [];
$(document).on('click','[name=opt1]',function(){
addOrRemoveBoxes(this.value);
//show contents of boxArr
if(boxArr.length == 0){
$('#output').html('nothing :/');
}
else{
$('#output').html(boxArr.join(" -> "));
}
});
});
function addOrRemoveBoxes(ID){
var arrayIndex = boxArr.indexOf(ID);
if(arrayIndex > -1){
boxArr.splice(arrayIndex, 1);
}
else{
boxArr.push(ID);
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h1>Choose</h1>
<input type="checkbox" name="opt1" id="opt1_1" value="ENG"> <label for="opt1_1">hello</label> <br>
<input type="checkbox" name="opt1" id="opt1_2" value="DUT"> <label for="opt1_2">hallo</label> <br>
<input type="checkbox" name="opt1" id="opt1_3" value="SWE"> <label for="opt1_3">hej</label>
<br><br><h2>Array contains:</h2>
<div id="output">nothing :/</div>
Side note: with [name=opt1] we select all the elements with name="opt1" attribute.
I have a form which contains radio boxes.
<input type="radio" name="categoryid" id="category420" value="420" onclick="checkCategory();" > Category1
<input type="radio" name="categoryid" id="category1314" value="13,14" onclick="checkCategory();" >Category2
<input type="radio" name="categoryid" id="category594" value="594" onclick="checkCategory();" >Category3
When the radio elements value attribute is a comma separated list (13,14) I need the elements Id attribute to change.
In the example above, when the second category is selected then "CategoryIDs=13,14" should be passed to the action page not categoryid. But for the other two categories it should pass categoryid value.
I cannot edit the action page.
The question: How can I change the radio buttons Id attribute in JQuery?
Change the Id
Based on your requirement to have only one Id (categoryid/s) then you could change the Id using JQuery, before the form is submitted.
JSFiddle working example - http://jsfiddle.net/daTYY/
JQuery
$(function() {
$('input:radio[name=categoryid]').change(function() {
if ($(this).val().indexOf(",") >= 0) {
$(this).attr("id","newId");
}
});
});
Update a hidden input
Add a hidden input named categoryids. Then use JQuery to check if categoryid contains a comma and if it does populate categoryids with the value.
JSFiddle working example - http://jsfiddle.net/KVs79/
HTML
<input type="radio" name="categoryid" id="categoryid1" value="13,14" />Category2
<input type="radio" name="categoryid" id="categoryid2" value="404" />Category3
<input type="hidden" name="categoryids" id="categoryids" value="" />
JQuery
$(function() {
$('input:radio[name=categoryid]').change(function() {
if ($(this).val().indexOf(",") >= 0) {
$("#categoryids").val("13,14");
}else{
$("#categoryids").val("");
}
});
});
I have this issue with enabling and disabling section of fields if other section of fields have specific value.
Consider jsfiddle for html code.
Conditions are
If all the fields of partA are selected as No, then enable partB.
If all the fields of partB are selected as No, then enable partC.
Try 1
First I tried disable elements of PartB and PartC which did not work.
$(function () {
$('.group').attr('name','partB').find('input').attr('disable', true);
$('.group').attr('name','partC').find('input').attr('disable', true);
});
I am not sure how would make sure if all the child elements are selected as No in a group div.
jsBin demo
Having this HTML:
<div class="group" id="partA">
<span> PART A</span><br/>
Option 1
<input type="radio" name="optionsRadios1" value="option1"/>Yes
<input type="radio" name="optionsRadios1" value="option2"/>No
<br />
Option 2
<input type="radio" name="optionsRadios2" value="option1"/>Yes
<input type="radio" name="optionsRadios2" value="option2"/>No
</div>
jQ:
$(function () {
$('#partB, #partC').find('input').prop('disabled', true);
function testChecked(){
var $par = $(this).closest('.group');
var $rad2 = $par.find('[value="option2"]');
var allNo = $rad2.filter(':checked').length == $rad2.length;
$par.next('.group').find(':radio').prop('disabled', !allNo);
if(!allNo){
$par.nextAll('.group').find(':radio').prop({'disabled':true, 'checked':false});
}
}
$('.group :radio').change(testChecked);
});
The above will work also for more than 2 radio groups per .group
Your errors:
"disable", "true" should be "disabled", "true"
<label> can control only one inner element (so I removed it.)
<div> afaik is not supposed to have a name attribute (so I assigned an ID)
I have multiple check boxes and i want them to display the same content when each of them is clicked. Now when I click on one check box, the content appears, but until I unclick it the next checkbox won't display any content. I want the all the contents to be displayed as long as check boxes are clicked. any tip with this.
I tried this:
function showTime(days){
var showTime = document.getElementById("time_schedules");
var days = document.getElementById("schedule");
if (days.checked) {
showTime.style.display = "Block";
}
else{
showTime.style.display = "none";
}
}
Insert some class attribute to all your checkboxes so you can select them, then capture the click event, iterate over all checkboxes and perform whatever you need to do (setting label etc).
I recommend using some javascript library such as jquery, for example:
<input type="checkbox" name="cb1" class="cb" />
<label for="cb1" class="cblabel">label1</label>
<input type="checkbox" name="cb2" class="cb" />
<label for="cb2" class="cblabel">label2</label>
$('.cb').bind('click', function() {
$('.cblabel').each(function(i,v) { v.innerHTML = 'hello'; });
});
