Hiding all elements with the same class name?

Question

I\'m trying to hide elements with the same class name (float_form), but I\'m also trying to use the script below to show them (all of the float_form class divs are initially

Answer 1

Try :

function showClass(a){
 var e = [];
 var e = getElementsByClassName(a);
 for(i in e ){
    if(!e[i])return true;

    if(e[i].style.display=="none"){
       e[i].style.display="block"
    } else {
       e[i].style.display="none"
    }
 }
 return true;
}

demo : showClass("float_form");

Answer 2

vanilla javascript

function toggle(className, displayState){
    var elements = document.getElementsByClassName(className)

    for (var i = 0; i < elements.length; i++){
        elements[i].style.display = displayState;
    }
}

toggle('float_form', 'block'); // Shows
toggle('float_form', 'none'); // hides

jQuery:

$('.float_form').show(); // Shows
$('.float_form').hide(); // hides

If you're looking into jQuery, then it's good to know that you can use a class selector inside the parameters of $ and call the method .hide().

$('.myClass').hide(); // all elements with the class myClass will hide.

But if it's a toggle you're looking for, use .toggle();

But here's my take on a good toggle without using jQuery:

function toggle( selector ) {
  var nodes = document.querySelectorAll( selector ),
      node,
      styleProperty = function(a, b) {
        return window.getComputedStyle ? window.getComputedStyle(a).getPropertyValue(b) : a.currentStyle[b];
      };

  [].forEach.call(nodes, function( a, b ) {
    node = a;

    node.style.display = styleProperty(node, 'display') === 'block' ? 'none' : 'block';
  });

}

toggle( '.myClass' );

No jQuery needed

const toggleNone = className => {
  let elements = document.getElementsByClassName(className)
  for (let i = 0; i < elements.length; i++){
    if (elements[i].style.display === "none") {
      elements[i].style.display = "";
    } else {
      elements[i].style.display = "none";
    }
  }
}

const toggleVisibility = className => {
  let elements = document.getElementsByClassName(className)
  for (let i = 0; i < elements.length; i++){
    let elements = document.getElementsByClassName(className);
    if (elements[i].style.visibility === "hidden") {
      elements[i].style.visibility = "";
    } else {
      elements[i].style.visibility = "hidden";
    }
  }
}

// run 
toggleNone('your-class-name-here'); // toggles remove
// or run 
toggleVisibility('your-class-name-here'); // toggles hide

Answer 5

Using jquery

$(".float_form").each(function(){
    if($(this).css("display") == "none"){
        $(this).show();
    }else{
        $(this).hide();
    }
});
