loading

问题 I'm making finishing touches on my site and am struggling to make the load of the page look less jumpy. best way to show you what i mean is to show the site: http://marckremers.com/2011 (Still not complete, in alpha phase) As you can see the contents sticks to the left, loads a ton of jquery and images into the page, and only then click into place (centre). I'm wondering if there is a way i can make it click into place first and then load the elements? I tried putting the reposition script

问题 hey everyone, here is the site SEE BELOW I have a slight jquery problem and I cant seem to figure out how to debug it. the strip of thumbnails is supposed to scroll when you hover over it. When the page loads, or it loads on a hard refresh, they dont scroll. If I refresh the page (normally, not a hard refresh), it works fine. Any ideas? ----------------UPDATE------------------- Here is a clean version with no other code in the way: Link here And Here is the JS Code I am using to produce the

问题 I am trying to load some CSV files into BigQuery from Google Cloud Storage and wrestling with schema generation. There is an auto-generate option but it is poorly documented. The problem is that if I choose to let BigQuery generate the schema, it does a decent job of guessing data types, but only sometimes does it recognizes the first row of the data as a header row, and sometimes it does not (treats the 1st row as data and generates column names like string_field_N). The first rows of my

问题 I'm working with a JSF2 webapp. When I'm navigating between different pages they normally load fast; less than 100 ms. Sometimes though, for no apparent reason, it takes several seconds. I've been trying to find some common denominator for when this occurs, but it happens regardless of page and regardless if I have visited the page several times before. Also, after a page has been slow to load, the next time I load it, it will load fast again for some time. It all seems to happen randomly. I

问题 I have tried to get several examples that I have found on here and the internet with out success. Goal: To display a animated gif while php scripts run. Background: This page is loaded via iframe. The php script I have tests 3 vpn connections and then displays a check (good) or an X (bad). The php portion works, but since there is a delay while testing I want to display the animated gif progress bar. Running Apache on CentOS 5.7 Currently this is done in a single file named: status.php I

问题 I have a label on a splash screen that is displayed for 4 seconds. I am trying to make the label display the loading process as a percentage. Obviously, this is just to show the user that the program is actually starting up and not actually "loading" anything. Is there a way that I can have the label display the percentage (going from 1% to 100%) within 4 seconds? A bit lost on how to do this. 回答1: Put a Timer control on the form, and set its Interval property to 40 and its Enabled property

问题 I'm doing a tutorial for rails animated loading page but the problem is that I get the following message undefined method `remote_function' .I've done some research and it seems that "remote_function" is deprecated.Can anyone tell me please how to I make the code work on rails 3.1 : onload="<%= remote_function(:url => { :action => :get_content_to_display } ) %>" Thanks for helping 回答1: Rails 3.1 prefered to use unobtrusive javascript. So you should use javascript framework (for ex. JQuery) to

问题 In one of my recent projects I need to perform this simple task but I'm not sure what is the most efficient way to do so. I have several large text files (>5GB) and I need to continuously extract random lines from those files. The requirements are: I can't load the files into memory, I need to perform this very efficiently ( >>1000 lines a second), and preferably I need to do as less pre-processing as possible. The files consists of many short lines ~(20 mil lines). The "raw" files has
