动画表格列以隐藏/显示它

Question

I have a very simple table, i try to animate the first column if i press on it.

After the click it should animate to the left, so that it is not fully displayed anymore:

Then after another click, it should animate back again

I tried to achieve this with jquery, but nothing happens:

 var main = function() { $boolean = true; $(".test").click ( function() { if ($boolean) { $boolean = false; $(".test").animate ( { 'left':'-=100px' }, "fast" ); } else { $boolean = true; $(".test").animate ( { 'left':'+=100px' }, "fast" ); } } ); } $(document).ready(main); 

 table { border: 1px solid black; } table td { border: 1px solid black; } table th { border: 1px solid black; } .test { color: red; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <table> <tr> <th class="test">Filename</th> <th>value</th> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> </table> 

Why is it not animating and how can i solve it? Thank you

Here is a working solution:

 var main = function() { $boolean = true; $(".test").click ( function() { if ($boolean) { $boolean = false; $(".test").animate ( { 'max-width':'10px' }, "fast" ); } else { $boolean = true; $(".test").animate ( { 'max-width':'300px' }, "fast" ); } } ); } $(document).ready(main); 

 table { border: 1px solid black; } table td { border: 1px solid black; } table th { border: 1px solid black; } .test { color: red; overflow: hidden; max-width: 300px; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <table> <tr> <th class="test">Filename</th> <th>value</th> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> </table>

If you add on more animating property like opacity, you will see that it works. So animation is working.

$(".test").click
(
   function()
   {
      if ($boolean)
      {
         $boolean = false;
         $(".test").animate
         (
            {  opacity: 0.5,
               'left':'-=100px'
            },
            "fast"
         );  
       }
       else
       {
            $boolean = true;
            $(".test").animate
            (
                {   opacity: 0.25,
                    'left':'+=100px'
                },
                "fast"
            );  
       }    
   }
);

Try this and you will see animation working.

You have to add a fixe witdth to your table and add this property :

  table-layout: fixed;
  width:200px;

And then you can use this javascript :

var main = function()
{
    $boolean = true;

      $(".test").click(function(){
                if($boolean){
              $boolean = false;
              $( ".test" ).animate({ 
                  width:"20px",
                }, 1500 );
             } else {
                    $boolean = true;
                $( ".test" ).animate({ 
                  width:"100px",
                }, 1500 );
             }
      });
}
$(document).ready(main);

You need to animate width not left property. Try this one :

var main = function(){
  $boolean = true;
  $(".test").click(function(){
    if ($boolean){
      $boolean = false;
      $(".test").animate({'width':'-=50px'},"fast");  
    }else{
      $boolean = true;
     $(".test").animate({'width':'+=50px'},"fast");  
    }    
  }
)}

Additionally you should change css for .test like this:

.test {
  color: red;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
  display: block;
}

You cannot change left or top for position: static elements. Try making them relative position to preserve their real position.

 var main = function() { $boolean = true; $(".test").click( function() { if ($boolean) { $boolean = false; $(".test").animate({ 'left': '-=100px' }, "fast" ); } else { $boolean = true; $(".test").animate({ 'left': '+=100px' }, "fast" ); } } ); } $(document).ready(main); 

 table { border: 1px solid black; } table td { border: 1px solid black; } table th { border: 1px solid black; } .test { color: red; position: relative; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <table> <tr> <th class="test">Filename</th> <th>value</th> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> <tr> <td class="test">File1</td> <td>Test</td> </tr> </table>
