load

I'm trying to load a DIV element from an external page into my current page using the Ajax/jQuery.ajax function. While I have successfully been able to load an entire external page, I can't seem to load just the DIV element. Here's my code: $("a").click(function() { /* grabs URL from HREF attribute then adds an */ /* ID from the DIV I want to grab data from */ var myUrl = $(this).attr("href") + "#external-div"; $.ajax( { url: myUrl, success: function(html) { /* loads external content into current div element */ $("#current-div").append(html); } }); return false; }); It grabs the HREF attribute

I can load an image when it is loaded, by doing: <img style="display:none;" src="big3.jpg"> <script type="text/javascript"> $('img').load(function(){ $(this).css({'display':'block'}) }); </script> But what I want is to load the div when all img is loaded, but this is not working, why? : <div style="display:none;"> <img src="big3.jpg"> </div> <script type="text/javascript"> $('div').load(function(){ $(this).css({'display':'block'}) }); </script> As @Kolink said, divs don't load. This code will show the div when all the images inside the div have loaded. (untested) var $images = $('div img');

This question already has an answer here: How to create a JavaScript callback for knowing when an image is loaded? 8 answers I have the following line of javascritp $("#hero_image img").attr('src', src); to change an image. The following lines then do whatever they do based on the images new width which I was calling through $("#hero_image img").width(); . However, how do I ensure that this image has fully loaded before getting the width, otherwise I will be returned with the old width? Setting a timeout isn't reliable enough. You can get the width in the .load() event handler which fires

I tried the following: $.load("Views/chatBox.html").appendTo('body') is not working! TypeError: $.load is not a function EDIT :The answer should be only one line of code,that's enough,I think I dont understand why placing container at the bottom of body and loading external page into that is not what you need? What you can try is this: <script type="text/javascript"> $(function() { $("#container").load("Views/chatBox.html",function(){ $(this).clone().appendTo("body").remove(); }); }); </script> But im not 100% sure about this code... :) Nope, all those answers are incorrect because they rely

Is there a way to load a module twice in the same python session? To fill this question with an example: Here is a module: Mod.py x = 0 Now I would like to import that module twice, like creating two instances of a class to have actually two copies of x . To already answer the questions in the comments, "why anyone would want to do that if they could just create a class with x as a variable": You are correct, but there exists some huge amount of source that would have to be rewritten, and loading a module twice would be a quick fix^^. Yes, you can load a module twice: import mod import sys del

Session.load/get方法均可以根据指定的实体类和id从数据库读取记录，并返回与之对应的实体对象。 其区别在于： 如果未能发现符合条件的记录，get方法返回null，而load方法会抛出一个ObjectNotFoundException。 Load方法可返回实体的代理类实例，而get方法永远直接返回实体类。 load方法可以充分利用内部缓存和二级缓存中的现有数据，而get方法则仅仅在内部缓存中进行数据查找，如没有发现对应数据，将越过二级缓存，直接调用SQL完成数据读取。 Session在加载实体对象时，将经过的过程： 首先，Hibernate中维持了两级缓存。第一级缓存由Session实例维护，其中保持了Session当前所有关联实体的数据，也称为内部缓存。而第二级缓存则存在于SessionFactory层次，由当前所有由本SessionFactory构造的Session实例共享。出于性能考虑，避免无谓的数据库访问，Session在调用数据库查询功能之前，会先在缓存中进行查询。首先在第一级缓存中，通过实体类型和id进行查找，如果第一级缓存查找命中，且数据状态合法，则直接返回。 之后，Session会在当前“NonExists”记录中进行查找，如果“NonExists”记录中存在同样的查询条件，则返回null。“NonExists
