I am trying to show/ hide set of web parts on click. I already wrote the coding and I can hide/show web parts one by one on click and the reason is that each web part has unique Id. Now I am facing with problem because I cannot hide 6 web part together on click and show 6 others. I tried to add different to a wiki page in SharePoint. so I can add 6 web part to each of them and then I have one id for each set, but it didn't work! If someone can help me how to reach "one" ID for set of web parts in SharePoint I would appreciate.

This is my JavaScript coding for each web part and it works well but too long!:

function showhideReport(){
 var div =document.getElementById('WebPartWPQ9')
 div.style.display=(div.style.display=="none") ? "block" : "none";
 if(document.getElementById('WebPartWPQ3').style.display=="block")
 document.getElementById('WebPartWPQ3').style.display="none";
 if(document.getElementById('WebPartWPQ10').style.display=="block")
 document.getElementById('WebPartWPQ10').style.display="none";
 if(document.getElementById('WebPartWPQ4').style.display=="block")
 document.getElementById('WebPartWPQ4').style.display="none";
 if(document.getElementById('WebPartWPQ5').style.display=="block")
 document.getElementById('WebPartWPQ5').style.display="none";
 if(document.getElementById('WebPartWPQ13').style.display=="block")
 document.getElementById('WebPartWPQ13').style.display="none";

}

Thank you

Tnx, I had some fun with your question, applying an OOP approach

Paste as snippet in Chrome Controls: 

function DIVManager( selector , numbers){
    var manager=this;
    function DIV(element){
        var div=this;
        div.state=element.style.display!=='none';
        div.style=function(key,value){
            element.style[key]=value;
            div.state=element.style.display!=='none';
        }
        div.show = div.style.bind(this,'display','block')
        div.hide = div.style.bind(this,'display','none')
        div.toggle=function(){
            div.state ? div.hide() : div.show();
            div.state=!div.state;
        }
    }
    manager.divs=[];
    manager.numbers=[];
    document.querySelectorAll(selector).forEach(function(element,nr){
        manager.numbers.push(nr);
        manager.divs.push(new DIV(element));
    });
    function action (){
        var args = Array.prototype.slice.call(arguments);
        if(args.lenght===1)args=manager.numbers;
        manager.divs.forEach(function(element,nr){
            console.log(nr,element);
            if(args.indexOf(nr)>-1) element[args[0]]();
        });
    }
    manager.show=action.bind(this,'show');
    manager.hide=action.bind(this,'hide');
    manager.toggle=action.bind(this,'toggle');
}
var wpM=new DIVManager("div[webpartid]");
wpM.hide(1,3,5);
wpM.toggle(1);
var searchBox=wpM.divs[0];
searchBox.style('zoom',3);
searchBox.style('backgroundColor','pink');
searchBox.style('opacity',.7);
var rotation=0;
window.setInterval(function(){
      searchBox.style( 'transform',String.format("rotate({0}deg)",rotation++ ));
}, 10);

Address the web parts by giving them a common class and then use the following:

document.getElementsByClassName

Instead of 

document.getElementById

  • How do I add a custom class name to web parts? I can't seem to find an answer to this anywhere. – Eric K Oct 31 '18 at 14:45

You can use jQuery's starts-with selector:

jQuery( "[attribute^='value']" )

i.e. to hide / unhide webparts:

jQuery( "[id^='WebPartWPQ']" ).each(function() {
  jQuery(this).toggle();
});

  • Thanks it works for each web part. do you know how can I have one ID from 6 web part? how can I put them in one div so I can do same coding as you said? just like something that BellZBob said above? – Shaghayegh Apr 4 '16 at 9:42
  • You can use "div[id^='WebPartWPQ']" as a selector and it will not matter where on the page they are, it will just get every div with an ID starting with WebPartWPQ – Colin Apr 4 '16 at 15:34

Please do f12 in browser and check your webpart id. It will add prefix automatically like "MSOZoneCell_WebPartWPQ3". Please pass webpart id with prefix in javascript and test it again.
