javascript - array is not working in a function which is inside for loop of jquery -


i stuck @ point,its worpress mediauploader. want upload images, 1 function 1 image have several upload buttons unique id want 1 function thats why created loop, on click of each button media uploader open there problem saving selected image, not getting image url in value. pls new jquery , javascript. tried various methods 1 of them screenshot of thing want->here

jquery(document).ready(function($){ var b = ["#upload-button-1", "#upload-button-2", "#upload-button-3","#upload-button-4","#upload-button-5","#upload-button-6","#upload-button-7","#upload-button-8"];  var d =[".procircle-1", ".procircle-2",".procircle-3",".procircle-4",".procircle-5",".procircle-6",".procircle-7",".procircle-8"]; var j;  var c = ["#grid-image-1", "#grid-image-2", "#grid-image-3","#grid-image-4","#grid-image-5","#grid-image-6","#grid-image-7","#grid-image-8"]; var i;  for(i=0; i<=b.length; i++)     {         for(j=0;j<=c.length;j++){         $(b[i]).on('click',function(e){             e.preventdefault();             if( mediauploader ){             mediauploader.open();             return;             }              mediauploader = wp.media.frames.file_frame= wp.media({                  title:'choose picture procedure ',                 button:{                     text:'choose picture'                 },                  multiple:false                                                              });               mediauploader.on('select',function(){                  attachment= mediauploader.state().get('selection').first().tojson();                 $(c[j]).val(attachment.url);                 $('.procircle-2').css({'background':'url(' + attachment.url + ')','background-repeat': 'no-repeat'});              });           mediauploader.open();          });         }     } });

i suggest doing following (if must keep ids etc):

$(document).on('click', '#upload-button-1, #upload-button-2, #upload-button-3, #upload-button-4, #upload-button-5, #upload-button-6, #upload-button-7, #upload-button-8', function(e) {     var match = e.target.id.match(/(\d+)/g);     e.preventdefault();     if(mediauploader) {         mediauploader.open();         return;     }      mediauploader = wp.media.frames.file_frame = wp.media({         title:'choose picture procedure ',         button:{             text:'choose picture'         },         multiple:false                                                      });      mediauploader.on('select', function(){         var attachment = mediauploader.state().get('selection').first().tojson();         var id = '#grid-image-' + match[1];         $(id).val(attachment.url);         $('.procircle-2').css({'background':'url(' + attachment.url + ')','background-repeat': 'no-repeat'});     });      mediauploader.open(); });

this removes loop , delegates handler create 1 click handler rather 1 per loop iteration currently, , creates single mediauploader select handler. finally, match corresponding input event target performed click. should work, although might need play around bit, , refactored nicer. hope helps.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
