• set highchart margin

  - by user1392330

  I have built a a higcharts charts and I am displaying them one at a time on mouseover. The jquery creates a floting div (depending on the cursor) with a border line 1px solid black and then the highchart method is being called to draw the chart. The thing is that highcharts exceed and left and bottom border is not shown. I tired 'margin' : chart: { renderTo: 'graph', defaultSeriesType: 'line', zoomType: 'x', margin: [ 10, 10, 10, 10] }, and still it does the same thing.

• Is there a way to catch assignments to or reads from an undefined property in the Spider-Monkey Java

  - by avri

  The Spider-Monkey JavaScript engine implements the noSuchMethod callback function for JavaScript Objects. This function is called whenever JavaScript tries to execute an undefined method of an Object. I would like to set a callback function to an Object that will be called whenever an undefined property in the Object is accessed or assigned to. I haven't found a noSuchProperty function implemented for JavaScript Objects and I am curios if there is any workaround that will achieve the same result.

Would it be prudent to store the session variable in the shared instance in order to maintain the session?

• I need to encrypt the names of my http form elements

  - by William Calleja

  I have a form with certain elements, input boxes, check boxes etc. I need to encrypt the names of these input boxes and check boxes. I'm currently using a Rijndael encryption/decryption method through c# however this is making the encrypted names too long to be passed in a post. Is there a better way to get decent encrypted names? my purpose is to have the names encrypted before the post happens so if someone views the code behind the names are already encrypted.

• How can I override the attribute assignment in an active record object?

  - by ryeguy

  I know you can do this with virtual attributes, but what if the column actually exists? For example, my model has a raw_topic column. When raw_topic is set, I want artist and song_title to be set based off of raw_topic's contents. Ideally, I'd like to override the raw_topic= method, but rails doesn't seem to like that. What's the proper way of doing this? Is a callback the only way?
