• Store a long string into mult array

  - by QLiu

  Hello All, I have a long string arrays, which looks like that var callinfo_data=new Array( "1300 135 604#<b>Monday - Friday: 9:00 a.m. to 5:30 p.m. AEST</b>", //Australia .. "0844000040#<b>lunedì-venerdì ore 10:00 - 17:00 CET</b>", //Switzerland (it) "212 356 9707#<b>Hafta içi her gün: 10:00 - 18:00</b>", //Turkey "08451610009#<b>Monday - Friday: 9:00 a.m. to 6:30 p.m. GMT</b>", //UK "866 486 6866#<b>Monday - Friday: 7:00 a.m. to 11:00 p.m. EST</b><br />Saturday: 9:00 a.m. to 8:00 p.m. EST", //USA "+31208501004#<b>Monday - Friday: 9:00 a.m. to 7:30 p.m. GMT+1</b>", //other countries " # "); As you see, it contact Phone number and open time. I can use split to separet them into info=callinfo_data[n].split("#"); two sections, And then i can represent them in HTML like "<div id ='phoneNumber'>"+info[0]+"</div><div id='openTime'>"+info[1]+"</div>" But my display phone number function will read the cookie variables, and then select the right contact info to display. Like, phone=callinfo_data[2].split("#"); if (locale == 'UK') details = phone[0]+ build_dropdown(locale); else if (locale == 'fr') details = 'French Contact Details<br>'+build_dropdown(locale); else if (locale == 'be') details = 'Belgian Contact Details<br>'+ build_dropdown(locale); else details = 'Unknown Contact Detail'; writeContactInfo(details); My questions are how I can build a function to load phone number and time based on my cookie variables, UK in a smart way. I can hard code everything, but i think it is too silly. I have to write a long code like: phone1= allinfo_data[0].split("#"); phone1= allinfo_data[1].split("#"); ... etc Second questions, how can I load this long arrays into easy access multi arrays? Thank you Regards, Qing

• JQuery UI Tabs - "Loading..." message

  - by Balu

  All, I am using Jquery UI nested tabs. I was just wondering if there is any way to display an AJAX Spinner image next to the tab text, while the tab is loading. I do not want to change the tab text to "Loading..". Consider that when multiple tabs are loading at the same time or one after the other, the spinner image should be displayed next to each loading tab.. Any Suggestions? Thanks

• Simple 2-color differential image compression

  - by Groo

  Is there an efficient, quick and simple example of doing differential b/w image compression? Or even better, some simple (but lossless) streaming technique which could accept a number of frames as input? I have a simple b/w image (320x200) stream, displaying something similar to a LED display, which is updated about once a second using AJAX. Images are pretty similar most of the time, so if I subtracted them, result would compress pretty well (even with simple RLE). Is something like this available?

• can widgets be cached ?

  - by movieuser

  Is there a way to cache widgets. For example if you place your widgets on high volume websites then each time when someone access that site, a call will be made to your server to get the widget code. This way my server can get too much overloaded just to display the widget . Can I cache the widget HTML code and place it on some server like Akamai. Any suggestions or tips highly appreciated. Thanks in advance.

  Hi there, I'm trying to find a way to make dingbats appear exactly the same in Firefox, Chrome, Safari and IE. I noticed that the Dingbats appear the same in IE/Chrome/Safari, HOWEVER - in Firefox - they look "thiner". For example - try to visit the following page: http://en.wikipedia.org/wiki/Dingbat You'll notice that when viewing that page in Firefox - the characters look different in comparison to Chrome/IE. Does anybody know why and how can I cause Firefox to display the characters EXACTLY like they appear in Chrome/IE? Thx, Oren.
