document

问题 I'm working with a script and have found the following, which I really can't find any info of what it means (function($) { $(document).ready(function(e) { ... bla bla bla ... }); }) (jQuery); Is (function($){}) (jQuery); the same as $(function () {}); ? and if so, why would somebody define twice document.ready ? 回答1: No, it's not the same. It's an anonymous function which is being passed the jQuery object, to insure that it is available as the local variable $ within the scope of the function

问题 I need to be able to open any file from Safari in my app via the "Open in" feature.

问题 I have a list of service that each have a number of fields that are structured like this Service1* ServiceID* NetID* Country* price* xxx* xxx* 10 fields in total* Service2* ServiceID* NetID* Country* price* xxx* xxx* 10 fields in total* I have arranged currently where each service is its own document for a total of 1,180. However when a user visits my site and wants to select a service, the server would fetch all 1180. With just 100users firebase would reading 100k docs. I was thinking of

问题 I want to load some jQuery code before the DOM is ready. I want to make a flash file transparant as the DOM loads. I was going to use something like this but Flash is initilized before the DOM loads. jQuery(document).ready(function(){ jQuery('object:not(:has(wmode))').each(function(){ jQuery(this).attr('wmode', 'transparent'); jQuery(this).prepend('<param name="wmode" value="transparent">'); jQuery(this).children('embed').attr('wmode', 'transparent'); }); }); Any ideas on how to do this? EDIT

问题 I want to insert DocB' into DocA using the VBA code: Selection.InsertFile DocB. DocA is a normal document in every regard. DocB has 2 sections. The first is 'normal' stuff. The second section (properly marked with a Section Break/Next Page) has a new set of left and right margins. When DocB is inserted into DocA with the above VBA command, all formatting (fonts, spacing, etc.) EXCEPT that the margins in the second section of DocB don't carry into DocA. (The Section Break/New Page marker is

问题 Does binding an event on document have any performance concerns? i.e: $(document).on('mouseenter mouseleave', function(e){ if (e.type === 'mouseenter'){ $(this).find( //some element and do something... Vs $(".myElement").hover(function(){ $(this).find( //some element and do something... I think keeping a track via document will use more processing power then assigning the event only a limited DOM elements? 回答1: You might need to implement a performance test to be sure about the actual

问题 Here is my code. XWPFRun run = runlist.get(0); double fontsize = (double)(run.getFontSize()); String fontfamily = (String)run.getFontFamily(); When it read the .docx file it will sometimes return -1 in font size and null in font family. I know that it's because they are default value but I don't want -1 and null I just want the name of that default value. How can I read it? 回答1: The font/character properties on a XWPFRun only return the override details, so settings which are different on

问题 I am using DOM parser and XPATH to parse a my XML file. I have changed a value of a node in the Document Object . However when I open my XML file, it doesn't show me any reflection.
