    <p>I have a problem with this code.</p> <pre><code>function checklistAntesdesalirUsuario() { if (plataforma == plataformaW8) { while (db == null) db = abrirDB(); var transactionUsuario = db.transaction(storeCLAntesDeSalirUsuarioNombre, "readonly"); var transaction = db.transaction(storeCLAntesDeSalirNombre, "readonly"); var objectStoreAntesDeSalirUsuario = transactionUsuario.objectStore(storeCLAntesDeSalirUsuarioNombre); var objectStoreAntesDeSalir = transaction.objectStore(storeCLAntesDeSalirNombre); var requestUsuario = objectStoreAntesDeSalirUsuario.openCursor(); var request = objectStoreAntesDeSalir.openCursor(); var cursor; var cursorUsuario; var count = 0; var i = 0; var cargadoUsuarios = false; var queryChecklistAntesdesalirUsuario = new Array(); request.onsuccess = function (evt) { cursor = evt.target.result; seguir(); }; request.onerror = function(evt) { console.log("ERROR!"); } requestUsuario.onsuccess = function (evt2) { cursorUsuario = evt2.target.result; cargadoUsuarios = true; seguir(); }; requestUsuario.onerror = function(evt) { console.log("ERROR!"); } function seguir() { if (!cursor || !cargadoUsuarios) return; if (cursorUsuario &amp;&amp; cursor.value.id_check == cursorUsuario.value.id_check) { cursorUsuario.continue(); } else { cursor.continue(); } if (cursor &amp;&amp; cursorUsuario &amp;&amp; cursor.value.id_check == cursorUsuario.value.id_check) { var antesdesalir = new CLFinal(cursor.value.id_check, cursor.value.descripcioncheck, cursorUsuario.value.tarearealizada); queryChecklistAntesdesalirUsuario[i] = antesdesalir; i++; pintarListaChecklistAntesdesalirUsuario(queryChecklistAntesdesalirUsuario); } } } </code></pre> <p>What I'm trying is to get data from 2 storages. Sometimes the "cursor" gets data, and when "cursor.continue()" executes is OK, but other times it crashes.</p> <p>I don't know what to do...</p> <p>Can anyone help me? Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
