In vue, the v-for method is used to load local static images, and vuev-for method is used to load static images.
Put the local image in the vue-cli project in the assets Directory (the reason is that the vue image at the beginning of vue-cli is in, and all the images are in it );
Then v-for dynamically loads the image path.
Source code:
The result shows that although the img src path is loaded in the
Ajax request data, using the JS template for rendering, there is no lazy loading situationThe workaround is to use the JS template engine afterAnd there is a problem, the home page will have multiple interface requests, so in each Ajax request interface, after rendering the template is called// Picture Lazy Loading $ ("img.lazy""fadeIn"}). Removeclass ("lazy"To prevent repeated rendering, use the. Removeclass ("lazy");Jquery.lazyload lazy Load Invalid

Load | Data The criteria is to load data through a set of conditional expressions (Expression), which returns a collection of objects that meet the criteria.
The primary interface is Icriteria, implemented as a Criteriaimpl class, and this class is internal decorated so that it cannot be displayed outside the assembly.
NHibernate provides us with a method Createcriteria in the session object that returns t

Let's take a look at the "State of view", that is, viewstate, in our view of the ASP.net generated page code, we can see the following code, that is ViewState existence form
Objects that can be serialized (serialized to save objects as encoded) can be stored in viewstate. General ViewState is not encrypted is BASE64 encoding, can also be configured in the Web.config encryption, the specific information can be queried.The role of ViewState in ASP.net is to save the state of the
To add this effect, first figure out the loading of the page and the sequence of event execution, see this simple example:
Execution Result: 9 rows >14 rows >11 rows, 9 lines of code placed in different positions, the result remains the same. To understand the above order, if you want to let the page before loading display jquery Mobile loader, and then the page data request execution, pictures and other multimedia after loading, and then close the loader, you can follow the follo
the filter to postpone the close session until the page results are obtained. This can be achieved using spring opensessioninviewfilter (which is a filter).

3) Manually load the required child table data from the database cache into the JVM memory. For example, classroom has a one-to-many relationship with student entity classes (many-to-many also apply), i.e.

Now, let's look at how we can solve this problem by executing the program after the DOM has finished loading.
Two people are introduced first. One, the author of jquery: John Resig II, the world class master of JavaScript: Dean Edwards. (Everyone should remember these two geniuses!) )
jquery has a function to solve DOM loading $ (document). Ready () (abbreviated is $ (FN)), very easy to use! John Resig in the Pro JavaScript techniques, there's a way to handle DOM loading, which is the principl
Problem Description: jquery's character set is Utf-8,load method after loading GB2312 code static page, the occurrence of Chinese garbled.
a.php
Copy Code code as follows:
b.php
Copy Code code as follows:
echo "I have Chinese in it";
?>
Solution:
Method One: Converts the encoding format of two pages into UTF8
Method Two: Add a line to the beginning of the b.php: header ("content-type:text/html; c
Traditionally, loading JavaScript files is the use of
(1) Strict reading order. Because browsers read JavaScript files in the order in which they appear in the Web page (2) Performance problems. The browser uses "sync mode" to load To solve these problems, you can use the DOM method to dynamically load JavaScript files.
Copy Code code as follows:
function Loadscript (URL) {
var script =
1) 9 lines of code to be slightly delayed execution, otherwise it is possible to refer to the JS file has not been loaded, this time call Showloader method, is not correctly executed, can not show the loader
2 shutdown loader can be placed in Document.ready or window.onload, specifically to see the implementation of the page needs.
3 If the speed is fast enough, two pictures in an instant load complete, it may not see the obvious loader display and sh

There is a big difference between cluster, distributed and load Balancing in PHP, the following article I will give you specific to write a cluster, distributed and load-balanced between the specific differences, say not much, let us take a look at it.
The concept of clustering
Computer clusters work closely together to complete calculations with a loosely integrated set of computer software and/or hardwar
