<p>I am working on a piece of code that has a substancial memory leak, I am posting an example function but my entire 11,000 line code has similar functions repeated all over. I am experiencing an average of 5Mb memory leak when I click the Refresh Button. The logic behind the refresh button is to call the empty function of the object. I have researched all over for cyclic references and closures but I am not really sure if the way I set everything to an empty array is correct or should I set everything to null ? Any help would be great. I have to use IE as the app is on IE. Sadly no chrome tools for me :( </p> <pre class="lang-js prettyprint-override"><code>/** * Represents the tasks for the currently loaded patients. */ var foo = { loaded: false, overdueTaskCounts: [], unscheduledTaskCounts: [], currentTaskCounts: [], scheduled: null, patientTasks: {}, tasks: {}, taskNumber: 0, /** * Unpacks the JSON received from the CareCompass service for the CareCompass task counts. * @param reply - The JSON representing the data returned from the CareCompass service. */ unpack: function unpackTasks(reply) { var taskCounts = reply.data; * * //This function populates the variables declared above**// this.scheduled = taskCounts.scheduled; }, /** * Removes all the task information related to the loaded patients. * @param none */ empty: function emptyTasks() { this.loaded = false; this.overdueTaskCounts = []; this.unscheduledTaskCounts = []; this.currentTaskCounts = []; this.scheduled = null; this.patientTasks = {}; } } </code></pre>

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.
