Most efficient method for revealing all concealed divs using JavaScript

I have a large div containing multiple hidden divs that can be displayed individually or all at once. Here is an example of how it's structured:

<div class="maindiv">
   Print "<a href=javascript:show()>Click here to show all</a>
   <a href="javascript:showhide(document.getElementById('div1'))">Show/hide div1</a>
   <div id="div1" style="display:none;">.....</div>
   <a href="javascript:showhide(document.getElementById('div2'))">Show/hide div2</a>
   <div id="div2" style="display:none;">.....</div>
   ....
</div>

The showhide() function effectively shows or hides a specified div, and the show() function can display all divs like so:

function show(){
   div1.style.display="block";
   div2.style.display="block";
   ...
}

However, having to manually enter each div reference for 100 divs is inefficient. Is there a way to automatically find and display all hidden divs within the maindiv class without enumeration?

Consider utilizing a common css class name that is defined in a similar manner:

.invisible{
   visibility:hidden;
}

Then you can simply target the elements with that class and remove it. If you are working with Internet Explorer 9 or higher, you can try the following:

var elements = document.getElementsByClassName("invisible"); 
for(var i = 0; i < elements.length; i++)
{
   elements[i].className = ""; //assuming only the invisible class is set, otherwise a search and replace is needed
}

If you need to accommodate older browser versions, there are alternative methods to gather all the necessary elements such as

document.getElementsByTagName("div")

I believe this solution may be effective

http://jsfiddle.net/abc123/

function displayContent() {
    var elements = document.getElementsByClassName("container");
    var count = elements.length;
    for( var x = 0; x < count; x++) {
        elements[x].setAttribute("class", "display");
    }        
}

Don't forget to adjust your css accordingly

.display section {
    visibility: visible !important;
}

The use of 'important' is recommended due to the presence of inline styles

Experiment with jQuery by attempting these methods:

$("*").show();

or

$(parentElem).find("*").show();

or

$(":not(:visible)").show();
// This targets all elements, rather than just the visible ones.

For more information on CSS selectors, visit w3 - css selectors, MDN - css pseudo classes, and explore jQuery's $(), $().find(), $().filter() methods.

Upon reviewing your code below, I noticed that it's almost functional. To make it work, simply change id='div1' to class='hid' and follow the steps outlined below:

   <a href="showhide(document.getElementById('div1'))">Show/hide div1</a>
   <div id="div1" style="display:none;">.....</div>

Here is the solution to the problem. I encountered a similar issue, but managed to resolve it by referencing this helpful post and following the provided instructions.

Take a look at my own code snippet below, which functions as intended:

For my CSS styling, I used the following:

<style>
     .hid {}
</style>

Next, I implemented a simple button to control the visibility of the content:

<button id="see" type="button" onclick="clickSee();">Show More ...</button>

Below is the Javascript code I used, utilizing JQuery 3.2.1 to change the button's function for toggling content visibility:

If you haven't used JQuery before, simply include the following script in the <head></head> section:

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

<script>
    function clickSee() {
       document.getElementById("see").innerHTML = "... Show Less";
       var divs = document.getElementsByClassName("hid");
       for (var i = 0; i < divs.length; i++){
           divs[i].style.display = "block";
       }
  //I use JQuery
       $("#see").attr("onclick", "clickHide()");
    }

    function clickHide() {
       document.getElementById("see").innerHTML = "Show More ... ";
       var divs = document.getElementsByClassName("hid");
       for (var i = 0; i < divs.length; i++){
           divs[i].style.display = "none";
       }
       //I use JQuery
       $("#see").attr("onclick", "clickSee()");
   }
</script>
