IndexedDB wildcard at start and end of searchterm -


this topic explains how use wildcards ad end of searchterm using indexeddb.

i looking way add wildcard @ end , @ start of searchterm. in sql be: like '%searchterm%'.

how can achieve indexeddb? here code:

function getmaterials() {     var materialnumber = $("#input").val();     var transaction = db.transaction(["materials"]);     var objectstore = transaction.objectstore("materials");      var request = objectstore.opencursor(idbkeyrange.bound(materialnumber, materialnumber + '\uffff'), 'prev');     $("#output").find("tr:gt(0)").remove();      request.onsuccess = function (event) {          var cursor = event.target.result;         if (cursor) {             var newrow = '<tr><td>'+ cursor.value.materialnumber +'</td>'+                  '<td>'+ cursor.value.description +'</td>'+                  '<td>'+ cursor.value.pieces +'</td>'+                  '<td>'+ cursor.value.price +'</td></tr>';              $('#output').append(newrow);              cursor.continue();         }     }; };

edit:

i achieve letting indexdb return rows , narrow down in javascript. there must better approach in terms of performance.

if (cursor.value.materialnumber.indexof(materialnumber) != -1){      //add result... }

this not how idb intended used. if want text searching, parse text tokens, store tokens, use index on tokens, , lookups on index pointer full text.

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. :)
