问题
Background :
We have Many lines in page , once we click on each line, we are displaying pop up....
Requirement :
Short : close the other pop-up when we open one pop-up
Long : When we click on 1st line, then its displaying 1st pop up , now when we click on 2nd or 3rd or any other line, it should close 1st pop up & display the other pop up....
This is working fine if we have only two lines as in Codepen1 , but if we have more than two lines, its not closing other pop up as in Codepen2....
I tried this below code :
document.querySelector(\'.white_content:not(' + lightIdString + ')\').style.display=\'none\'
Code snippet :
var target;
var imageUrl = "https://i.imgur.com/RzEm1WK.png";

Keep currently open lightID in openID and use following function to open and close the popup onClick of link for close and open. in openPopUp and closePopUp you will receive html element. define both function globally
openID=null;//initial state
function closePopUp(el){
el.style.display='none';
openID=null
}
function openPopUp(el){
///console.log(" open is called ",id)
if(openID!=null){
closePopUp(openID)
}
el.style.display='block';
openID=el;
}
$('.container').append(
'<a id ="' + layer.name + '" onclick="openPopUp('+lightID+')"' +
'<div class="textcontainer" contenteditable="true" ' +
'style="' +
'left: ' + layer.x + 'px; ' +
'top: ' + layer.y + 'px; ' +
'font-size: ' + layer.size + 'px; ' +
'">' + layer.text + '</div></a>' +
'<div id="light' + layer.name + '" class="white_content" style="' +
'left: ' + layer.x + 'px; ' +
'top: ' + layer.y + 'px; ' + '"> content <a href="javascript:void(0)" ' +
'onclick="closePopUp('+lightId+')">Close</a></div> <div>'
);
document.getElementById(lightId).style.left = layer.x + document.getElementById(layer.name).offsetWidth + 'px'
// Above is POP UP Code
}
}
