Using Checkboxes To Update Ui In Realtime
Solution 1:
As far as I can see, your problem boils down to link checkboxes (that seem to have been generated in some way) to "division" parts of your html that you want to hide. Plus, you have to inject javascript code in the page (so I guess the less code the better).
One approach could be as follows:
// Wrap the code in an anonymus function, to avoid clustering the global space.
(function (domElements) {
// This is the callback that will fire when a checkbox is clicked.functionclickCallback() {
// the context of this callback is the DOM element thus we can access its attributes through this.// extract the checkNumber of the class of the element. This number is the link to the division that we want to hide/show.var checkNumber = ((/ editoropt(\d*) /).exec(this.className))[1],
checkBox = document.getElementById('checkboxopt' + checkNumber),
division = document.querySelectorAll('.editoraccvar' + checkNumber)[0];
// Hide/show division, update checkBox state.toggleElements(division, checkBox, window.getComputedStyle(division).display === 'none');
}
functiontoggleElements(division, checkBox, isShown) {
// Toggle the division (show/hide) accordingly.
division.style.display = isShown ? 'block' : 'none';
// Due to the fact that the event listener is attached to the parent of the checkBox, we need to maintain consistency manually.
checkBox.checked = isShown;
}
// Remove from the array of DOMElements those that aren't checkboxes and add a click event listener to each of them.
domElements
.filter(function (el) {
return el.className.indexOf('editoropt') !== -1;
})
.forEach(function (el) {
el.addEventListener('click', clickCallback, false);
});
// Call the function passing the dom elements with class '.seq-box-form-field' as argument. Checkboxes are contained within them. Also, transform the nodelist// into a proper array so that methods defined in Array.prototype can be used.
})([].slice.call(document.querySelectorAll('.seq-box-form-field')));
The code is commented and (I think) quite self-explanatory. However, if you have any doubt or want me to elaborate any point further, please, let me know.
Finally, here's the working fiddle.
UPDATE
Same function (more or less) but now it accepts an array of values that will correspond to the initial state of the checkboxes:
(function (domElements, cbState) {
functionclickCallback() {
toggleElements(this.className);
}
functiontoggleElements(className, initialShow) {
var checkNumber = ((/ editoropt(\d*) /).exec(className))[1],
checkBox = document.getElementById('checkboxopt' + checkNumber),
division = document.querySelectorAll('.editoraccvar' + checkNumber)[0],
isShown = initialShow === undefined ? window.getComputedStyle(division).display === 'none' : initialShow;
division.style.display = isShown ? 'block' : 'none';
checkBox.checked = isShown;
}
domElements
.filter(function (el) {
return el.className.indexOf('editoropt') !== -1;
})
.forEach(function (el, index) {
el.addEventListener('click', clickCallback, false);
toggleElements(el.className, cbState[index]);
});
// Initial state of the checkboxes goes in the second parameter. The index in the array correspond to the checkbox position in the page.
})([].slice.call(document.querySelectorAll('.seq-box-form-field')), [false, false]);
Here's the Fiddle to play with. Hope it helps.
Solution 2:
The other half of your problem, not addressed in the other answer has to do with events. Generally, adding an "onclick" attribute to the actual HTML is considered bad practice. You can attach event handlers with Javascript.
var a = document.getElementById("checkboxopt1");
a.addEventListener("click", exFunction, false);
See the manual for more info about how to use this.
Solution 3:
Looks like that you need the elements that have the class "field-summernote", but not the class "editorbdyvar".
You can use a query selector to get elements by class name using the default tools from Javascript:
var items = document.querySelectorAll('.field-summernote');
for(var i = 0; i<items.length; i++){
var current = items[i];
if( current.className.indexOf('editoraccvar') < 0) //not found: -1return;
//now you can manipulate the current elementconsole.log(current);
}
Solution 4:
well ... you should either learn javascript, DOM, HTML and CSS or hire an somebody that can do it. in my opinion the latter would come cheaper.
if not, here goes something to put in your script.js file.
the checkboxes must have the id="toggleTextareas" respectively id="toggleInputs".
(functionisolateScope() {
tryInit();
functiontryInit() {
if(document.readyState!="complete"){
setTimeout(tryInit, 100);
}else{
createUI();
init();
}
}
functioncreateUI(){
var div=document.createElement("div");
div.className="addon-floating-toolbar"
div.style.position="fixed";
div.style.zIndex="999999";
div.style.background="#EEE";
div.style.padding="5px";
div.innerHTML='<input type="checkbox" id="toggleTextareas">toggle Textareas<br>'
+'<input type="checkbox" id="toggleInputs">toggle Inputs';
document.body.appendChild(div);
}
functioninit() {
var tta=document.getElementById("toggleTextareas");
var ti=document.getElementById("toggleInputs");
var textareaVisible=true;
var inputVisible=true;
tta.onclick=toggleTextareas;
ti.onclick=toggleInputs;
functiontoggleTextareas() {
var elms=document.querySelectorAll("textarea");
textareaVisible=!textareaVisible;
if (textareaVisible) {
show(elms);
}else{
hide(elms);
}
}
functiontoggleInputs() {
var elms=document.querySelectorAll("input");
inputVisible=!inputVisible;
if (inputVisible) {
show(elms);
}else{
hide(elms);
}
}
functionshow(collection) {
for (var i = 0; i < collection.length; i++) {
collection[i].style.display="";
}
}
functionhide(collection) {
for (var i = 0; i < collection.length; i++) {
collection[i].style.display="none";
}
}
}
})();
let me know if it works, cheers.

You can traverse all your fields and generate a checkbox that will toggle it open/close for each of your fields. Also set the checkbox label as innerText of the corresponding field.
// Block to be run
generateCheckboxes = function() {
var button = document.getElementById("generateButton");
button.parentNode.removeChild(button);
// grab all elements with the class, .field-summernotevar uiblocks = [].slice.call(document.querySelectorAll('.field-summernote')).filter(function(x) {
return x.className.indexOf('editoraccvar') >= 0
});
if (!uiblocks.length) return;
var chcontainer = document.createElement('div');
chcontainer.style.display = "inline-block";
document.body.insertBefore(chcontainer, document.body.children[0]);
uiblocks.forEach(function(x) {
var cdiv = document.createElement('div');
var clabel = document.createElement('label');
clabel.innerHTML = x.innerText.trim();
var cinput = document.createElement('input');
cinput.type = 'checkbox';
cinput.checked = true;
cinput.onchange = function(ev) {
var checked = this.checked;
x.style.display = checked ? "" : "none";
}
cdiv.appendChild(clabel);
cdiv.appendChild(cinput);
cdiv.appendChild(document.createElement('br'));
chcontainer.appendChild(cdiv);
})
};#container {
width: 150px;
}
input {
float: left;
}
label {
width: 120px;
display: block;
float: right;
text-align: left;
}<buttononclick="generateCheckboxes()"id="generateButton">Generate Checkboxes</button><divid="example"class="field-summernote editoraccvar"><br/><br/><span>Zero</span><br/><textarea></textarea></div><divid="example1"class="field-summernote editoraccvar1"><br/><br/><span>One</span><br/><textarea></textarea></div><divid="example2"class="field-summernote"><br/><br/><span>Two</span><br/><textarea></textarea></div>
