asp.net mvc - jquery code working in every browser except ie8 -


this scenario. creating image upload using iframe. situation this, if hovers on iframe, div opens on has 2 buttons. 1 button select image clear image present in iframe.

this code of view:

   @using (html.beginform("index", "landingsetting", formmethod.post, new { enctype = "multipart/form-data" }))                             {                                 @html.validationsummary(true)     <div id="menu" class="tip_trigger">         <iframe width="731" height="335" src="@viewdata[" htmlloc "]"></iframe>         <div id="inner" class="hover-text">             <table>                 <tr>                     <td width="50%" align="center" valign="middle">                         <img id="slctbtn" src="../../images/landing/s_btn.png" />                     </td>                     <td width="50%" align="center" valign="middle" style="padding-left: 200px">                         <img id="clearbtn" src="../../images/landing/c_btn.png" />                     </td>                 </tr>             </table>         </div>     </div> }

here code hover:

 <script type="text/javascript">         $(document).ready(function () {             //tooltips             $(".tip_trigger").hover(function () {                 tip = $(this).find('.hover-text');                 tip.show(); //show tooltip             }, function () {                 tip.hide(); //hide tooltip                     });             //             });     </script>

and here code 2 buttons:

<script type="text/javascript">         $(function () {             $('#slctbtn').click(function () {                 $('#htmla').click();             });             $('#htmla').change(function () {                 $('form').submit();             });             $('#clearbtn').click(function () {                 $(this).load('@url.action("clear", "landingsetting")');                 alert('content cleared!');                 window.location.reload(true);             });         });     </script>

note: htmla hidden input type file

this controller code:

  public actionresult clear()         {             system.io.file.delete(request.mappath("/css/html/imgs/ex1.jpg"));             return redirecttoaction("index");         }

the problem works fine in other browsers except ie8.only hover code working in ie8. need make work in ie8. can that? thanks

note: in ie click event getting triggered because can see alert doesnt trigger @url.action method

the following may of interest:

jquery trigger file input

it seems problem due click no being triggered because file input display:none or visibility:hidden. try setting opacity:0 , filter:alpha(opacity = 0); instead — input's click wont disabled — or better still use off-screen positioning adardesign suggests.

if doesn't work, other tricks i've seen used regards triggering click on file upload position input floats on top of desired button , has it's opacity faded out 0. means click of input still accessible user, gui of button shows through. it's quite illegant hack though really.

update

seeing above not problem, try modifying things , see if improving:

$('#clearbtn').click(function(){   $.ajax('@url.action("clear", "landingsetting")')     .done(function(response){       alert('response: '+response);       alert('content cleared!');       window.location.reload(true);     })     .fail(function(jqxhr, textstatus){       alert('an error occured ' + textstatus);     })   ; });

as long @url.action("clear", "landingsetting") renders correctly formatted url see no reason why above have issue. if view source on page in-question should able scroll code responsible , find url being produced. if url exists , accessible ie8, issue else.

possible explanation

ah, ok seemed work. guess why seem ie8 has issue alerts occuring directly after jquery ajax requests. guess alert halts process, , after clicking alert away page have reloaded window.location.reload(true); before request got chance reach server. reason other browsers work because allow ajax call occur despite alert, , has time communicate before reload.

... solution, in future use callback make ajax request has finished :)
