load

问题 I have a mobile site, with all the content on one PHP page, and the pages (or div's rather), are swapped with jQuery. I want to speed up the load time, and the bulk of what has to be loaded are images on each persons bio. I would like to use jQuery to only load the persons image when their bio is navigated to. I'm guessing I need to use AJAX because we can't rely on a page refresh. Any pointers? Thanks! 回答1: you can use the jquery load to load the image after the dom is completed to load $

问题 Firstly, I'd like to say that I do not want to use any libraries that are not provided with Python 2.7.10. The same question was posted on Stack Overflow but was answered with the Requests library. I have a script that logs into Roblox.com using urllib2. To check if there is a captcha before I try to log in, I wanted to do check_captcha = re.findall('recaptcha_image', newlogin) but roblox needs to redirect to the captcha login page AND the captcha has to load onto the page. So how can I make

问题 I want to load jquery asynchronously on a page and then load an other script which depends on jquery (it executes jquery code when loaded). But how can I detect if jquery has finished lodading. Is there an event for this in jquery which fires when the library finished loading? In theory I could load jquery like this: <script async src="jquery.js" onload="jqueryloaded()"></script> but I want the code to work on older browsers too which may not support the async and onload attributes. (In this

问题 I have a data file and a corresponding schema file stored in separate locations. I would like to load the data using the schema in the schema-file. I tried using A= LOAD '<file path>' USING PigStorage('\u0001') as '<schema-file path>' but get an error. What is the syntax for correctly loading the file? The schema file format is something like: data1 - complex - - - - format - - data1 event_type - - - - - long - "ends '\001'" data1 event_id - - - - - varchar(50) - "ends '\001'" data1 name

问题 I have saved data which was saved using NSUserDefaults. I was under the impression that if there was nothing saved to the key already (first time app is run) it would default to 0. This however doesn't seem to be the case. Here is what I have: To save: - (void)viewWillDisappear:(BOOL)animated { [[NSUserDefaults standardUserDefaults] setInteger:setbatteryHealthCalculated forKey:@"healthValue"]; [[NSUserDefaults standardUserDefaults] synchronize]; } To load: - (void) viewWillAppear:(BOOL

问题 I need to get the title of a remote page by URL. The code works in FFX, but not chrome. Anyone have any ideas? $(document).ready(function(){ $("title").remove(); $("head").load("http://www.latentmotion.com title"); }); 回答1: Here, this works in all browsers $.get("http://www.latentmotion.com", function(response){ alert((/<title>(.*?)<\/title>/m).exec(response)[1]); }); You can test it here http://jsfiddle.net/N7D5r/ And if you want to avoid jQuery altogether var getXhr = (function () { if (

问题 I have a C++/CLI GUI application and I want to display an image as a visual aid for the user to see what step in a procedure they're at. This image will need to be changed each time the user selects the new step. Currently I'm using a picture box and have an image loaded from the disk at run time. So there are a few things I need to know here: Is a picture box the best thing to use for this purpose or is there another control that would better suit? How do embed the images in the executable

问题 I would like to know how can I load a file lol.txt from src folder into my close method. The code so far: public void close() throws IOException { boolean loadFromClasspath = true; String fileName = "..."; // provide an absolute path here to be sure that file is found BufferedReader reader = null; try { if (loadFromClasspath) { // loading from classpath // see the link above for more options InputStream in = getClass().getClassLoader().getResourceAsStream("lol.txt"); reader = new
