  javascript regex
  I am trying to build a regexp from static text plus a variable in javascript. Obviously I am missing something very basic, see comments in code below. Help is very much appreciated:var test_string = “goodweather”;// One regexp we just set: var regexp1 = /goodweather/;// The other regexp we built from a variable + static text: var regexp_part = “good”; var regexp2 = “\/” + regexp_part + “weather\/”;// These alerts now show the 2 regexp are completely identical: alert (regexp1); alert (regexp2);/

  javascript jquery ajax json cors
  What I am trying to do is to have a page on the HTTP protocol sending an AJAX call to the same Web server but using HTTPS. Both the requesting page and the AJAX handler are on the same server, having the same domain and port. (I.e., only difference is the protocol.) To illustrate,Fromhttp://www.example.com/index.phpTriggers a jQuery AJAX call tohttps://www.example.com/authenticate.php?user=123&password=456(I am hoping to pass the password through HTTPS to make it encrypted over the Internet.

  The problem: I have a site with a recently installed SSL certificate that is very dependent on POST calls over AJAX. The site worked fine on Internet Explorer 8 before the SSL certificate, but now does not.Since I haven’t been able to get a good way to read any error messages, I haven’t been able to pin down where the bug is coming from. I will try to list as much as I know/ have figured out, and I greatly appreciate any suggestions.What I know:On IE8, the site will not perform any AJAX POST cal

  I’ve been reading lots of the other posts, and no doubt it’s my inexperience with jQuery that is giving me trouble, but there are lots of things close to what I’m trying to accomplish. I have a div where I have a vertical navigation set of buttons. Inside that I want the other divs (child divs) that will be shown or hidden based on the navigation button clicked by the user. I want all of these divs to be in the same location on the screen…so, basically like a tabbed form but with vertical navi

  php csv quotes quoting
  Is there a native function or solid class/library for writing an array as a line in a CSV file without enclosures? fputcsv will default to ” if nothing is passed in for the enclosure param. Google is failing me (returning results for a whole bunch of pages about fputcsv), and PEAR’s libraries do more or less the same things as fputcsv.Something that works exactly like fputcsv, but will allow the fields to remain unquoted.currently: “field 1″,”field 2”,field3hasNoSpacesdesired: field 1,field 2,fi

  javascript d3.js
  Here is my confusion(jsfiddle-demo) about the category10 function in D3:> var a = d3.scale.category10() > a(0) “#1f77b4” > a(10) //the expected different color value “#2ca02c”If I call directly the returned function of calling category10 , things go like this> d3.scale.category10()(0) “#1f77b4” > d3.scale.category10()(10) //the SAME color! Why? “#1f77b4″In my opinion, calling d3.scale.category10()(10) should yield the same value as calling a(10).What is going wrong here?
