I have a website where there are five checkboxes, a div that contains another divs which each div contains five input hidden that have a value 1 or empty. That value comes from DB.
That's an example to represent the div container with the divs:
<input checkbox value="a">
<input checkbox value="b">
<input checkbox value="c">
<input checkbox value="d">
<input checkbox value="e">
<div class="container">
<div class="content" data-name="combine">
<input type="hidden" value="" data-name="a" />
<input type="hidden" value="" data-name="b" />
<input type="hidden" value="" data-name="c" />
<input type="hidden" value="" data-name="d" />
<input type="hidden" value="" data-name="e" />
</div>
<div class="content" data-name="combine">
<input type="hidden" value="1" data-name="a" />
<input type="hidden" value="" data-name="b" />
<input type="hidden" value="" data-name="c" />
<input type="hidden" value="1" data-name="d" />
<input type="hidden" value="" data-name="e" />
</div>
</div>
In the javascript code i have this snippet:
if(elementLength > 0) {
$("[data-name='combine'] div.tagsProds").each(function() {
var element = $(this);
$.each(enabledChecks,function(i, v) {
if(element.find("input[name='"+v+"']").val() == "") {
element.append("<div class='blocked'></div>");
element.unbind("click");
element.addClass("js_noSortable");
}
});
});
}
The javascript first checks if the div.container has childs and if it has childs the code iterates each child. On each child i iterate the five each checkbox (enabledChecks) and i see if the input hidden are empty. What i need if that if the five input are empty then append the `div.blocked'.
As i don't have enough reputation to write a comment i write an answer.
First, i think that your answer is quite interesting if you're looking to find a way using a jQuery function, but as i don't know any function to do this i think that you can create an array() and when you check if the input has empty value push it to the array, when the loop finishes you check the length of the array() and if it matches with the number of your checkboxes then append the .blocked
If I understand the question correctly, you want to find divs matching some selector that have no child input elements with non-empty values. The .filter method seems like a good fit here:
$("[data-name='"+name+"'] div.tagsProds")
.filter(function() {
// assert that at least one child input has a value
var $inputsWithValue = $(this).find("input[name='avail_" + v + "'][value!='']");
return $inputsWithValue.length === 0;
})
.each(function() {
// now act on those value-less divs
$(this)
.append("<div class='blocked'></div>")
.addClass("js_noSortable")
.unbind("click");
});
Another selector-only option might look like:
$("[data-name='"+name+"'] div.tagsProds:not(:has(input[name='avail_" + v + "'][value!='']))")
.each(function() {
// now act on those value-less divs
$(this)
.append("<div class='blocked'></div>")
.addClass("js_noSortable")
.unbind("click");
});

Note that the examples above follow the selectors in your sample code, but won't work against your sample markup.

How to get previous input checkbox with name "checkthis" using queryselector on an element?
function findPreviousInputcheckboxCheckthis(ev) {
checkboxCheckthis = ev.target.querySelector( "input[name='checkthis']);
}
Edit: There are many more input checkboxes with name="checkthis" before and after the snippet I posted. They are nested in other element also.
I simply want the nearest previous checkbox in the html-source starting from the target, nested or not.
Based on your below comment, I have updated the answer snippet where you need to add parent div structure and then you can find the checkthis name attribute quickly. Please check below working snippet:
function findPreviousInputcheckbdfoxCheckthis(ev) {
var selectElement = document.getElementById(ev);
selectElement.querySelector('input[name="checkthis"]').style.visibility = "hidden";
}
<div id="div1">
<input name="checkthis" type="checkbox" value="previous">
<span>text here</span>
<input type="text" name="checkthis">
<input type="text" name="another">
<input type="text">
<input type="checkbox" value="next">
<input type="text" id="eventTarget" oninput="findPreviousInputcheckbdfoxCheckthis(this.parentElement.id)" placeholder="Previous checkbox">
</div>
Here, I have added div1 id and you can repeat the same by using using ID and rest the JavaScript will be same and it will find your first previous "name=checkthis" checkbox.
Hope this solution will be work for you!
Also, below is the link where I have used multiple repeat structure. Please refer it also:

I have a form with which a user can dynamically add text inputs. This generates a form with multiple text inputs that have the same name. If this form is submitted they overwrite each other. To solve this I need change the names so that they are appended with an incremented prefix when the form is submitted. Can anyone help?
Example of form (once three inputs have been added):
<form action="" method="post">
<td class="recipe-table__cell">
<input id="answer" name="the_answer" type="text" value="" >
<input id="answer" name="the_answer" type="text" value="" >
<input id="answer" name="the_answer" type="text" value="" >
</td>
<input type="submit" value="Submit">
</form>
Desired Post output on submission:
Array ( [1-answer] => test [2-answer] => ok [3-answer] => nice)
rather than Array ( [answer] => test )
First, select all of the elements that you want to add the attribute for. This can be done with .querySelectorAll().
Second, loop over those elements.
Third, use .setAttribute() to change the name attribute to append the index from the loop.
Note that you'll also want to increment the ID attribute, as you can't have duplicate IDs on the same page. You'll also want to swap your <td> elements for <div> elements to both allow .querySelectAll() to work correctly, and ensure valid markup.
This can be seen in the following example:
var inputs = document.querySelectorAll("form div input");
for (var i = 0; i < inputs.length; i++) {
inputs[i].setAttribute("id", "answer" + i);
inputs[i].setAttribute("name", "the_answer" + i);
console.log(inputs[i]); // Added purely to show the change
}
<form action="" method="post">
<div class="recipe-table__cell">
<input id="answer" name="the_answer" type="text" value="">
<input id="answer" name="the_answer" type="text" value="">
<input id="answer" name="the_answer" type="text" value="">
</div>
<input type="submit" value="Submit">
</form>
Hope this helps! :)
I am not sure if I am going about this correctly. I have a set of checkbox inputs. If someone selects the last check box all_users_check, I want a new form to appear where I will be listing all of the users in a drop down (haven't added the drop down yet). I thought I could do this by using the name of the input, but I am mistaken apparently as I am getting this error..
How else could I structure what I am doing so that if someone checks that option the new form displays?
<div class="user_dropdown">
<form action="">
<input type="checkbox" name="spectator_check" value=""> Spectators<br>
<input type="checkbox" name="member_check" value="" checked> Team Members<br>
<input type="checkbox" name="commissioner_check" value="" checked> Commissioner(s)<br>
<label for="all_users_check">
<input type="checkbox" name="all_users_check" value="" checked> Individual User<br>
</label>
</form>
</div>
<script>
$(".user_dropdown").hide();
$(".all_users_check").click(function() {
if($(this).is(":checked")) {
$(".user_dropdown").show();
} else {
$(".user_dropdown").hide();
}
});
</script>
This is how the page looks on load. Those fields are already checked for some reason.
Issues in your code.
.all_users_check that is looking for a class. Your element doesn't have a class so this isn't found. You can use a different selector to use the name attribute, https://api.jquery.com/attribute-equals-selector/.
This $(".user_dropdown").hide(); hides your whole form. You might want to move around your divs, or remove that altogether.
The checked attribute checks the field it is on. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input
Use the checked attribute to indicate whether this item is selected
<div class="user_dropdown">
<form>
<input type="checkbox" name="spectator_check" value=""> Spectators<br>
<input type="checkbox" name="member_check" value=""> Team Members<br>
<input type="checkbox" name="commissioner_check" value=""> Commissioner(s)<br>
<label for="all_users_check">
<input type="checkbox" name="all_users_check" value=""> Individual User<br>
</label>
</form>
</div>
<script>
//$(".user_dropdown").hide();
$("input[name='all_users_check']").click(function() {
if($(this).is(":checked")) {
$(".user_dropdown").show();
} else {
$(".user_dropdown").hide();
}
});
</script>
isset is a language construct and can't accept anything other than a variable as indicated by this warning on the linked to manual page:
Warning isset() only works with variables as passing anything else will result in a parse error.
You are not passing in a variable to the isset function, you are passing in a constant value, basically an array with a single string all_users_check. This is not a variable because you are not assigning it to a variable name. Try this instead:
if(isset($_POST['all_users_check']))
Here the variable being passed in is the superglobal $_POST, and you are checking to see if the index all_users_check is set inside of that array.
Update
To check if an input is empty or not via javascript, take a look at this question.
Try using this script, you have set the state of check boxes as checked by default.
<div class="user_dropdown">
<form action="">
<input type="checkbox" name="spectator_check" value=""> Spectators<br>
<input type="checkbox" name="member_check" value=""> Team Members<br><!-- removed 'checked' from this line -->
<input type="checkbox" name="commissioner_check" value=""> Commissioner(s)<br><!-- removed 'checked' from this line -->
<label for="all_users_check">
<input type="checkbox" name="all_users_check" value="" > Individual User<br> <!-- removed 'checked' from this line -->
</label>
</form>
</div>
<script>
$(".user_dropdown").hide();
$(".all_users_check").click(function() {
if($(this).is(":checked")) {
$(".user_dropdown").show();
} else {
$(".user_dropdown").hide();
}
});
</script>
For the other issue of showing the hidden section again, try whether class all_users_check is visible to click.
I'm having an issue with passing hidden values. I have a search field that onclick calls my javascript function with the intention of setting a hidden fields value further down the page.
<div class="search">
<input type="text" name="username" class="mySearch" value="">
<input type="button" class="myButton" value="" onclick="setSearch();">
</div>
My javascript, i is set outside of the function.
setSearch(){
if(i == 0){
$('input:hidden[name="search1"]').val($(".mySearch").val());
}
else if(i == 1)
{
$('input:hidden[name="search2"]').val($(".mySearch").val());
}
i++;
}
and then the field I'm try to set
<div class="sendallHolder">
<form method="post" action="getTweets.php">
<input type="hidden" name="fromTest" id="fromTest"/>
<input type="hidden" name="untilTest" id="untilTest"/>
<input type="hidden" name="latTest" id="latTest"/>
<input type="hidden" name="longTest" id="longTest"/>
<input type="hidden" name="search1" id="search1" />
<input type="hidden" name="search2" id="search2" />
<input type="submit" class="sendAll" value="Gather News!">
</form>
</div>
It runs through the loop twice but each time its not setting the values properly in my hidden fields. the dev tools in chrome tell me that the 'value' is popping up but no value is being set. I'm not entirely sure what I'm doing wrong.
Any ideas?
The :hidden selector doesn't do what you think. It matches elements that have been hidden using CSS, it doesn't match type="hidden" inputs. Just use
$("#search1")
since you have an id on the elements.
Use hidden input ID like this :
$('#search1').val($(".mySearch").val())
$(".mySearch").keyup(addhjc);
function addhjc(){
$('#search2').val($(".mySearch").val());
}
or
$('.myButton').click(function(){
$('#search2').val($(".mySearch").val());
});
also
function setSearch(){
if(i === 0){........
and define i var
Am trying to get the value of the hidden input fields on every click of a radio button. I have just posted a single div. I have a multiple div with same structure. I have successfully obtained the value of radio button but I want to get the value of hidden input now.
<div class="QA">
<h1> First Question</h1>
<input type="radio" id="check" name="q" value="A">Options 1</input>
<input type="radio" id="check" name="q" value="B">Options 2</input>
<input type="radio" id="check" name="q" value="C">Options 3</input>
<input type="radio" id="check" name="q" value="D">Options 4</input>
<input type="hidden" id="result" value="B" />
<br/>
<div id="result"></div>
</div>
<script>
$(document).ready(function() {
$("input:radio").change(function() {
checkResult(this);
});
});
function checkResult(el)
{
$this=$(el).parent("div.QA");
$this.slideUp();
}
</script>
Maybe you could try removing the hidden input entirely and indicate the correct answer using a data-* attribute. Something like:
<div class="QA" data-answer="B">
Then in your checkResult function you could retrieve this value using
function checkResult(el)
{
$this=$(el).parent("div.QA");
var answer = $this.data("answer");
$this.slideUp();
}
function checkResult(el)
{
$this = $(el).parents("div.QA");
$this.slideUp();
var x = $this.find('#result').val(); //find value of hidden field in parent div
}
Change your markup
multiple id's should not be used. Use class instead.
<input type="radio" id="check" name="q" value="A">Options 1</input>
to
<input type="radio" class="check" name="q" value="A">Options 1</input>
var $hidden=$(el).siblings("input[type='hidden']");
BTW you have lot of elements with same ID, not good
You can get the value of the hidden element by it's id.
var hiddenValue = $("#result").val();
You can use this in hidden function
function checkResult(el)
{
var hiddenValue = $("#result").val();
alert(hiddenValue);
}
