Retriving Data From IndexedDB -

i new in indexeddb. need fetch data per requirement. requirement :-

i have 1 object stored in indexeddb.

object format : -

var _obj = {     col_title : '1',     col_id : 'proxyserver#1235',     col_name : 'proxyserver',     col_version : ['task#1','task#2','task#3','task#4'] } 

i want fetch data according 'task#2'. had created index 'versionindex' using this

this.store.createindex('versionindex', 'data.col_version', {unique:false});

with multi-entry index.

// in onupgradeneeded store.createindex('colversionindex','col_version', {multientry:true});  // in query store.index('colversionindex').opencursor('task#2').onsuccess = function() {   var cursor = this.result;   if(!cursor) return;   console.log('got task %o', cursor.value);  };
