Toggle Between Mashup Charts

Qlik Sense mashups can be quite simple at first. The dev hub lets you create the files you need, connect to and app and drop in charts.

Here’s a simple example on how load three charts (hide two) then toggle between them using CSS and JavaScript.

		<div class="row my-row">
			<div id="QV03" class="qvobject"></div>
			<div id="QV02" class="qvobject"></div>
			<div id="QV03" class="qvobject"></div>


	<!--Error Popup-->
	<div id="popup">
		<button type="button" class="close" data-dismiss="modal" aria-label="Close" id="closePopup"><span aria-hidden="true">×</span></button>
		<p id="popupText"></p>


Lots going on here so lets break it down… in the main Qlik function we get three objects (charts) which we display in the HTML (below):

<div class="row my-row">            
<div id="QV03" class="qvobject"></div>            
<div id="QV02" class="qvobject"></div>            
<div id="QV03" class="qvobject"></div>        

We also have three buttons (bootstrap). Each button calls the same function and passes the ID of the Qlik object to it:

<input onclick="myToggleShowHide('QV01')"  type="radio" class="btn-check" name="btnradio" id="btnradio1" autocomplete="off" checked>                <label class="btn btn-outline-primary qlik_resize" for="btnradio1">Radio 1</label>

The function picks up the ID then by changing the CSS style display property shows (block) or hides (none) the object…

function myToggleShowHide(myID) {                     
// Sure this can be improved so it more reusable but its good enough for now
console.log(myID) ;                                            
if (myID === "QV01") {                        
document.getElementById("QV01").style.display = "block"                        
document.getElementById("QV02").style.display = "none"                        
document.getElementById("QV03").style.display = "none"                    
} else if (myID === "QV02") {                        
document.getElementById("QV01").style.display = "none"                        
document.getElementById("QV02").style.display = "block"                        
document.getElementById("QV03").style.display = "none"                    
} else if (myID === "QV03") {                        
document.getElementById("QV01").style.display = "none"                        
document.getElementById("QV02").style.display = "none"                        
document.getElementById("QV03").style.display = "block"    }                                       };

Finally in order for Qlik to recalculate the charts when they become visible you need to resize them, this is done using a callback in the main Qlik function which listens to the class of “qlik_resize” each button shares (highlighted in green above).

$(".qlik_resize").click(function() { qlik.resize();});
