How can I persist state of slideToggle() in my case?


I want javascript function slideToggle() to persist it's state. For now, everytime i refresh the page, it looses the information. i know it can be done using cookies or localstorage but i have failed to do so..

I would really be thankful if someone could show me how to implement a solution in my code;

//toggle hide/show shout box
$(".close_btnn").click(function (e) {   
    //get CSS display state of .toggle_chat element
            var toggleState = $('.toggle_chat').css('display');
    //toggle show/hide chat box
    $('.toggle_chat').slideToggle();

    //use toggleState var to change close/open icon image
    if(toggleState == 'block')
    {
        $(".header div").attr('class', 'open_btnn');
    }else{
        $(".header div").attr('class', 'close_btnn');

    }


});

This is the HTML/PHP of the page with the shoutbox;

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style type="text/css">

Solution

  • Here is how you can do it using localstorage.

    $(document).ready(function() {
    var $shoutBox = $('#shout-box');
    var isShoutBoxClosed = JSON.parse(localStorage.getItem('shoutBoxClosed'));
    if(isShoutBoxClosed){
    	$shoutBox.hide();
    }	
    //toggle hide/show shout box
    $(".close_btn").click(function (e) {
    	//save users preference on localstoage
    	localStorage.setItem('shoutBoxClosed', true);
        //toggle show/hide chat box
      $shoutBox.slideToggle();
    
    });
    	
    });
    .shout_box {
    background: #000000;
    width: 260px;
    overflow: hidden;
    position: fixed;
    bottom: 0;
    right: 10px;
    z-index:9;
    }
    .shout_box .header .close_btn {
    background: url(close_btn.gif) no-repeat 0px 0px;
    float: right;
    width: 15px;
    height: 15px;
    }
    .shout_box .header .close_btn:hover {
    background: url(close_btn.gif) no-repeat 0px -16px;
    }
    
    .shout_box .header .open_btn {
    background: url(close_btn.gif) no-repeat 0px -32px;
    float: right;
    width: 15px;

    }
