Multiple value Checkbox jquery issue - javascript

Hi I'm trying to get the values of a checkbox and assign the values checked to all checkboxed with the same id on the page. However my attempt is not working, here is what I'm doing
$('.add_button').click(function() { //they click a div named added
selected=$('#ssrBox').val(); //I get the id of the checkbox and the values however I only get one value.
id=$(this).attr('id'); //I find the id of the div which is ssrBox
$('#ssrBox').change(function() { // I find the rest of the checkboxes with the same id and hopefully make them select the same value
$('#ssrBox').add(selected); //have the value being checked for all
});
<div class="grs-multi-select-area" style="height:120px;width:150px;">
<div class="grs-multi-select-box ">
<input id="ssrBox" class="ssremployeeid" type="checkbox" name="ssremployeeid[]"
value="1312">
Amanda Becker
</div>
<div class="grs-multi-select-box "> // same as above I just collapsed it for viewing purposes
<div class="grs-multi-select-box ">
<div class="grs-multi-select-box ">
</div> //closes main div
I'm not getting the value for the checkbox and nothing is being checked. What I'm I doing wrong?

I am quite confused with what you are trying to execute.
You click a Div or a Checkbox?
The following might help -
Give a class to all the checkboxes.
Something like
$('#yourCheckboxID').click(function(){
var checkboxValue = $(this).val();
$('.yourCheckboxClass').attr('value',checkboxValue);
});
I can help more if you could create a small demo on jsfiddle.

Javascript: How to print input to <div> selected by class?

Edit: Thanks for the helpful answers so far! I'm still struggling to print the input to the "right" div, though. What am I missing?
Next to the input field, there is an option to select either "left" or "right". Depending on the selection, the input is to be printed eiether left or right on the click of a button. This is what I have - but it only prints to the left, no matter the selection.
jQuery(document).ready(function(){
$('.button').click(function(){
$('.input').val();
if ($('select').val() == "left"){
$('div.left').html($('.input').val());
}
else {
$('div.right').html($('.input').val());
}
});
});
</script>
Sorry if this is very basic - I am completely new to JS and jQuery.
I'm trying to print input from a form into a div. This is part of the source HTML modify (it's for a university class):
<input type="text" class="input">
<div class="left">
</div>
<div class="right">
</div>
Basically, text is entered into the field, and I need to print this text either to the "left" or the "right" div when a button is clicked.
So far, I have only ever dealt with divs that had IDs, so I used
document.getElementById("divId").innerHTML = ($('.input').val());
But what do I do now when I don't have an ID? Unfortunately, changes to the HTML source are not an option.
Thanks in advance!
Just use normal selectors, like css and jQuery does.
https://api.jquery.com/category/selectors/
in your case:
$('div.left').html($('.input').val());
As you see there are many ways to do this. You can get elements by tag name, class, id...
But the most powerful way is to get it with querySelector
function save() {
var input = document.querySelector('input').value;
document.querySelector('div.left').innerHTML = input;
}
<input type="text" class="input">
<button onclick="save()">Save</button>
<div class="left"></div>
<div class="right"></div>
There are plenty of other ways to target HTML elements, but the one you're looking for in this case is getElementsByTagName(). Note that this returns a NodeList collection of elements, so you'll additionally need to specify the index that you wish to target (starting at 0). For example, if you want to target the second <div> element, you can use document.getElementsByTagName("div")[1].
This can be seen in the following example:
let input = document.getElementsByTagName("input")[0];
let button = document.getElementsByTagName("button")[0];
let div2 = document.getElementsByTagName("div")[1];
button.addEventListener("click", function(){
div2.innerHTML = input.value;
});
<input type="text">
<button>Output</button>
<br /><br />
<div>Output:</div>
<div></div>
Since you have unique class names for each element, document.getElementsByClassName can be used. This will return an array of elements containing the class. Since you only have one element with each class name, the first element of the returned array will be your target.
<input type="text" class="input">
<button onclick="save()">Save</button>
<div class="left"></div>
<div class="right"></div>
<script>
function save() {
var input = document.getElementsByClassName('input')[0].value;
document.getElementsByClassName('left')[0].innerHTML = input;
}
</script>
This is one of the many ways to do what you want:-
Write the following in console:
document.getElementsByTagName("div");
now you can see the total number of div elements used in your current document/page.
You can select one of your choice to work on by using "index number"(as in array index) for that particular div.
Lets say your div having class name = "right" is the 3rd one among the other div elements in your document.
This will be used to access that div element.
document.getElementsByTagName("right")[2].innerHTML = "whatever you want to write";

Populate a hidden form field using the div of a drop menu (drop down menu is created using divs not select, option etc)

I have a form.
Please note I must use divs for creating the form drop down and not the select option method etc. It just has to be done that way. The code is below.
<form action="url.asp" method="get">
<div class="search-button"><i class="fa fa-search"></i><input type="submit" /></div>
<div class="search-drop-down">
<div class="title"><span>Choose Category</span><i class="fa fa-angle-down"></i></div>
<div class="list">
<div class="overflow">
<div class="category-entry" id="Category1">Category One</div>
<div class="category-entry" id="Category2">Category Two</div>
</div>
</div>
</div>
<div class="search-field"><input type="text" name="search-for" id="search-for" value="" placeholder="Search for a product" /></div>
<input type="hidden" id="ChosenCategory" name="ChosenCategory" value="CATEGORY1 OR CATEGORY2 (WHICHEVER SELECTED)" />
</form>
As shown in the code above I need to populate the hidden field value as per the chosen option which the user selects in the drop down.
I have used about 20 different variations of getElementById or onFocus functions but cannot get it to work.
The only thing I can get to work is the following JavaScript and it just populates the hidden field value with the first id ignoring completely which one has actually been selected(clicked) by the user;
var div = document.getElementById('DivID');
var hidden = document.getElementById('ChosenCategory');
hidden.value = div.innerHTML;
I'm running classic asp so if there is a vbscript way then great, otherwise if I have to use JavaScript to do it then as long as it does the job I'll be happy still.
A click handler on the options could be used to update the value.
No jQuery or any other external library is needed. Below is a working example. Of course, in your case the input element could be of type hidden, but I made it text here for the sake of demonstration.
//Add the click handlers
var options = document.getElementsByClassName('option');
var i = 0;
for (i = 0; i < options.length; i++) {
options[i].addEventListener('click', selectOption);
}
function selectOption(e) {
console.log(e.target);
document.getElementById('output').value = e.target.id;
}
div {
padding: 10px;
}
div.option {
background-color: #CCC;
margin: 5px;
cursor: pointer;
}
<div>
<div class="option" id="Category1">Category One</div>
<div class="option" id="Category2">Category Two</div>
</div>
<input type="text" id="output" />
You should be able to achieve what you're after with a fairly simple setup involving listening for clicks on two separate <div> elements, and then updating an <input> based on those clicks.
TL;DR:
I've put together a jsfiddle here of what it sounds like you're trying to make work: https://jsfiddle.net/e479pcew/5/
Long version:
Imagine we have 2 basic elements:
A dropdown, containing two options
An input
Here's what it might look like in HTML:
<div class="dropdown">
<div id="option-one">Option 1</div>
<div id="option-two">Option 2</div>
</div>
<input type="text" id="hidden-input">
The JavaScript needed to wire these elements up should be fairly easy, but let me know if it doesn't make sense! I've renamed things throughout to make things as explicit as possible, but hopefully that doesn't throw you off.
One quick thing - this is an incredibly 'naive' implementation of this idea which has a lot of potential for refactoring! However I just wanted to show in the most basic terms how to use JavaScript to make this stuff happen.
So here we go - first things first, let's find all those elements we need. We need to assign variables for the two different dropdown options, and the hidden input:
var optionOne = document.getElementById("option-one");
var optionTwo = document.getElementById("option-two");
var hiddenInput = document.getElementById("hidden-input");
Cool. Next we need to make a function that will come in handy later. This function expects a click event as an argument. From that click event, it looks at the id of the element that was clicked, and assigns that id as a value to our hiddenInput:
function valueToInput(event) {
hiddenInput.value = event.target.id;
}
Great - last thing, let's start listening for the clicks on specific elements, and if we hear any, we'll fire the above valueToInput function:
optionOne.addEventListener("click", valueToInput, false);
optionTwo.addEventListener("click", valueToInput, false);
That should get you going! Have a look at the jsfiddle I already linked to and see if it makes sense - get in touch if not.
Are you allowed to use JQuery in this project? It would make your life a lot easier. You can detect when a div is clicked and populate the hidden field.
This could do it:
$(document).ready(function() {
$('.category-entry').click(function() {
$('#ChosenCategory').val($(this).text()); }); });

Don't submit form if inputs are empty

I have two sets of data: "heat" and "cold", which are retrieved from another provider. This data is quite unorganized and I have removed lots of stuff in the code just to show the essential part of my problem. "Heat" and "cold" both contain properties that the user has to fill in. This property however is dynamic and the amount of properties is not fixed (hence it is in a loop as shown in the code).
My goal is to hide/disable the submit button, which is located all the way down, whenever one single input field in the list in either sets of data is empty. This should also preferably work on Internet Explorer 9, where the 'required' tag is not supported.
I have tried:
Adding the required tag. This unfortunately does not work in IE9 and I have some issues even in Google Chrome because it is still submitting my form. (I added the form tags too)
Adding Ng-show on the submit form. I checked whether the userInput is empty, but this still does not work.
Now you may ask, why wouldn't I just check in my controller whether these properties are empty in my submit method? While it is a good point, I can not access this dynamic data very easily in my controller. Hence, I need a solution that will hopefully fix this problem with no/mimimal effort in the controller.
Code:
<!--Start wrapper!-->
<div class="wrapper">
<div ng-repeat="(code, program) in data.old.heat">
<div class="row" ng-repeat="(componentId, component) in program">
<div class="inputForm">
<!--This field may not be left empty!-->
<input type="text" class="form" ng-model="component.userInput">
</div>
</div>
</div>
<div ng-repeat="(code, program) in data.old.cold">
<div class="row" ng-repeat="(componentId, component) in program">
<div class="inputForm">
<!--This field may not be left empty!-->
<input type="text" class="form" ng-model="component.userInput">
</div>
</div>
</div>
</div>
<!--End of wrapper !-->
<div class="submitPanel">
<button ng-click="submit()">Submit</button>
</div>
Here ya go : https://jsfiddle.net/DIRTY_SMITH/zxbe5rt0/
function validate(){
var text1 = document.getElementById('text').value;
if (text1.length > 0){
alert("went through");
return true;
}
alert("did not go through");
return false;
}
Not specific to angular, but you could check if it has characters via jQuery.
Html
<div class="submitPanel">
<button class="submit-btn" ng-click="submit()">Submit</button>
</div>
jQuery
$('#form input').blur(function()
{
if( $(this).val().length === 0 ) {
$(this).parents('.submit-btn').addClass('hide');
}
});
CSS
.hide{
display:none;
}
I have two options for you, but they both include ng-disabled (https://docs.angularjs.org/api/ng/directive/ngDisabled).
You can put this attribute on the button and you can either call a function on the scope in that attribute and check if all values are given.
So like: ng-disabled="checkInputs()".
Or
You wrap a form around all your inputs, give the form a name like name=form and set the required attribute on all inputs. (EDIT: you could use ng-required="true" for IE9.)
Then you could say ng-disabled="!form.$valid".

How to create a modal window using jquery and javascript to help a user make a choice

I need to create a modal window that contains a list of checkboxes. A user can select a checkbox (or several checkboxes). Depending on a user choise, a section(s) next to the list must appear or disappear OR change its opacity and ZOOM.
An example of what I need is below:
http://www.devart.com/dbforge/mysql/studio/ - here you can click the blue button in the sidebar (what product is right for me?)
Here is also similar example (but not exactly what I need) http://www.kaspersky.com/help-me-choose
So, I can create a modal in the way like this:
(if there are betters ways to do this, please tell me)
<script>
$(document).ready(function () {
$('.showmodal').on('click', function () {
$('.modal').fadeIn(1000);
});
$('.hidemodal').on('click', function () {
$('.modal').fadeOut(1000);
});
});
</script>
Then I can create a list of check boxes:
<div class="modal">
<div>
<b>What do you want to do?</b><br>
<input type="checkbox" name="option1" value="a1" checked>Question 1<br />
<input type="checkbox" name="option2" value="a2">Question 2<br />
</div>
</div>
Then I can creale a number of DIVs next to the checkboxes list and using jquery change its opacity when the mouse cursor is on top of the DIV... but
Q#1 HOW CAN I ANIMATE ITS ZOOM ? like in the first example.
Q#2 (the most important) HOW CAN I LINK...A CHECKBOX STATE WITH A SPECIFIC DIV? I mean, how can I show a specific div depending on what a checkbox is selected (or several)? What should I use: if else construction... or switch - case? Or something else ?
Thank you.
Use Twitter Bootstrap: modal
It's easy to use and save you from lots of work.
example as in: http://www.devart.com/dbforge/mysql/studio/
you could use jquery, suppose the images are:
<img src=".." id="img1" style="display: none;"/>
<img src=".." id="img2" style="display: none;"/>
Now the checkboxes:
<input type="checkbox" class="img1">
Now jquery:
$('input["checkbox"]').is(":checked"){
var img = $(this).attr("class");
$("#" + img).css("display","block"); //do your own stuff such as zoom..etc.. as you were saying
// add for uncheck, to hide the picture etc...
}

jQuery update form element

I have a form that I create a checkbox on a click of a button. I am using https://github.com/pixelmatrix/uniform which provides an update function to style dynamically create elements which does not work. I got a work around but my problem is that it also reset the already created elements so they double, triple etc.
They are wrapped in a div with a class of checker. Is there a way to check if the div is around it first before applying my $('.table').find('input:checkbox').uniform(). I have tried different examples but they dont seem to work with my code and my jQuery is still limit.
Thanks
<div class="checker" id="uniform-160">
<span>
<input type="checkbox" name="chbox" id="160" style="opacity: 0;">
</span>
</div>
jQuery:
$(".fg-button").live("click", function(){
$('.table').find('input:checkbox').uniform()
});
Try this:
$('.table input:checkbox').not('div.checker input').uniform()
