javascript - Get all Elements touching a rectangle -

-

I need to get all the elements whose bound rectangle has some arbitrary rectangle of my selection. I do not have a way to do this basically, and my best solution so far is to call a representative sample of the number within the rectangle, which is far from the correct, because it can remember the elements.

This is a performance nightmare that is going on every point in the rectangle, and therefore is not an option. Even if this is possible, then I do not think the elements are width: 0; Height: 0 , although this is not a huge concern for me.

I have the idea that how to reduce negative negatives by using the method of multiple points, but is that an real solution?

  1. Get for each element Touch your rectangle.
  2. For each element, check if there is a border rectangle and your rectangular intersection.

    If you have too many elements, and you can make assumptions such that the binding sequences of child elements of an element are always contained in the bounding text of the element, then some customization possible Are there. Or when elements are ordered in a particular way, but if any condition is possible for any HTML element, as is the CSS permission, you have to check them all.

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
