javascript - jQuery issues with the 'this' modifier and if/else statement -


ok, i'm trying make image can modified or moved in browser clicking on buttons on side of page, script in if/else statement isn't working i'd to. here's have far in jquery: 

<meta charset="utf-8"> <title>image mod</title> <link rel="stylesheet" type="text/css" href="css/style.css"> <script src="http://code.jquery.com/jquery-1.11.3.min.js"></script> <script src="js/main.js"> var menu = $('ul li').click(function() { console.log($(this).index());   if (menu = 0) { $('this').css('width', '80%') }  else if (menu = 1) { $('this').css('height', '80%')   }  else if (menu = 2) { $('this').css('height', '80%') }  else if (menu = 3) { $('this').css('top', '30') }  else if (menu = 4) { $('this').css('left', '50') }  else if (menu = 5) { $('this').css('left', -50') } else {  } }); </script> </head> <body>     <nav id="sidebar">         <ul>             <li>edit 1</li>             <li>edit 2</li>             <li>edit 3</li>             <li>edit 4</li>             <li>edit 5</li>             <li>edit 6</li>         </ul>     </nav>     <img class="active" src="images/picture.jpg" /> </body>

$('this') selector <this> tag.

change $(this)

in if statements, single = assignment , evaluate true if value on right non-zero. need use == test equality. should consider switch statement, so:

switch ($(this).index())  {     case 0: // stuff           break;     case 1: // more stuff           break;     default:           // no other match }
