    <p>I have a function which executes on click event, but the thing is that I want it to execute only once. </p> <p>The function that get's executed on click represents a google map plotting to an targeted element. The function looks like this : </p> <pre><code>Cluster.prototype.initiate_map_assembling = function(target, latitude, longitude) { var canvas = $(target).children(); var coordinates = new google.maps.LatLng(latitude, longitude); var options = { zoom: 9, center: coordinates, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map($(canvas)[0], options); var marker = new google.maps.Marker({ position: coordinates, map: map }); }; </code></pre> <p>And I'm running it on <code>click</code> event like this :</p> <pre><code>Cluster.prototype.initiate_google_maps_action = function() { var self = this; return $(this.maps_wrapper_class).each(function(index, element) { var canvas = $(element).parents().eq(3).find(self.map_canvas_wrapper_class); return $(element).on('click', function(ev) { var latitude = $(element).attr('data-latitude'); var longitude = $(element).attr('data-longitude'); self.initiate_map_assembling(canvas, latitude, longitude); ($(canvas).hasClass('selected')) ? $(canvas).removeClass('selected') : $(canvas).addClass('selected'); ev.preventDefault(); }); }); }; </code></pre> <p>What I want to achieve is stop the plotting each time I click the button, because it's only needed once since I'm only hiding the container div and not destroying it. So how could I do that ? I tried with temporary variables added when the function executes ( and setting it as true after the first time and as false when initiated ) and returning false if the temporary variable is true, but with little success as I could not return false inside the plotting function.</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.
