Describes the practice of Elastic Search engine in SpringBoot. Lab Environment ES version: 5.3.0 Spring bt version: 1.5.9 First of all, we need to install the elastic search environment. We 'd better install the visualization plug-in elasticsearch-head to make it easy for us to view data intuitively. Of course, this part can be referred to my post: Installation of

HTML structure:CSS style:. box {display:-webkit-box;/* old version, declare flexible box */-webkit-box-orient:vertical;/* old version, spindle direction */-webkit-box-direction:normal; * old version, reverse, positive sequence for normal */-webkit-box-pack:justify; /* old version, spindle on its way, both ends of the alignment */-webkit-box-align:center; /* old version, cross-axis on its way, shrink center */Display:flex; /* New, DECLARE elastic box *

CSS3 introduced a new box model-elastic box model, in fact, the previous article has already talked about a box-flex, today speaking of another two elastic box model properties Box-orient and box-direction.1,box-origent: horizontal or vertical distribution. Box-origent has two values: horizional (horizontal) and vertical (vertical), meaning the way the elements are arranged!The CSS code is as follows:Body {

(===vertical)Article { display:-webkit-box; height:100%; /* Note the property prefixed by this prefix, preceded by the value*/ -webkit-box-orient:vertical;}： Controlled by Box-flex,This acts on the child element, so that the child elements have ' elasticity ', and the ' elastic ' child elements can be scaled to fill the parent elementFor example, we set the ' elasticity ' of the first child element to 1Article Div:nth-child (1) { back

This is a very creative html5svg chat box drag-and-drop elastic rocking animation effects. The user can use the mouse to click or swipe the specified area on the chat box, the area will be a very elastic spring effect to open the Chat user list. When you click on a profile picture, you switch to the chat screen with the same flex effect, and the avatar is moved to the top right corner of the chat screen. Th

Beautiful and super-useful pop-up layer event class JS code, support a variety of dialog boxes, pop-up layer, etc., the pop-up layer can be dragged and dragged smoothly, the browser is well-compatible. Customizable content, headings, widths, buttons, and bindings correspond to the event of a simple and convenient implementation of the elastic layer, to add data or display detailed information and other functions.Follow my steps below.(1) Prepare the c

　　　　　　　　　　　　Physical experimentThe main topic: there is a vertical pipe with the ground, the pipe mouth and the ground between H, the tube has a lot of elastic ball, from the t=0, the first ball from the mouth to start falling, and then every 1s will have the ball from the current position of the ball to fall, the ball hit the ground to return to the original speed, the ball and the ball , the rate becomes the rate of the other ball at the end of the

To figure out how the relevance of the document search was calculated behind elastic search, I decided to do my own experiments to exploreThis blog is a good one to say.http://blog.csdn.net/dm_vincent/article/details/42099063And the blog itself is just translating official documentsHttps://www.elastic.co/guide/en/elasticsearch/guide/current/scoring-theory.htmlI'm going to test it.When searching for a document, a combination of the following underlying

can this problem be determined. 2: (Figure 2) Determine whether the last five points are in the same straight line. Second, let's talk about the idea of "elastic regression. In fact, elastic regression is more complex than inertial sliding. Why? This is because I don't need to care about the specific sliding distance when moving inertia. sliding a little more can also be done, just a little less. However

Simple implementation of javascript elastic movement effect, javascript Elasticity This article describes how to implement javascript elastic movement. We will share this with you for your reference. The details are as follows: Principle of elastic movement: acceleration, deceleration, and friction The running effect is as follows: The instance code is as follow

CSS flex-grow attributes of the Flexible elastic box model, flexibleflex-growInstance Make the second element three times the width of other elements: Div: nth-of-type (1) {flex-grow: 1 ;} Div: nth-of-type (2) {flex-grow: 3 ;} Div: nth-of-type (3) {flex-grow: 1 ;} Browser support for copying preview results The number in the table indicates the version number of the first browser that supports this attribute. The number following-webkit-,-ms-, or-

Mobile elastic sliding and sliding out-of-bounds solutions　　Mobile development will often encounter two problems, sliding is not sensitive, where to go to the slide, which is often said: elastic sliding. In one is the mobile development in the real machine will often encounter sliding out of bounds to see the background of the browser, this is very common. Let's make a summary of these questions first:The f

Experimental environment ES version: 5.3.0 Spring BT version: 1.5.9 First of all, of course you need to install the elastic search environment, it is best to install the visual plug-in Elasticsearch-head to enable us to visually view the data.Of course, this section can refer to my post:"Centos7 on Elastic search installation Pits Kee"Https://www.jianshu.com/p/04f4d7b4a1d3My ES is installe

The principle of elastic sliding A large slide is not a number of minor slides and is completed within a time period. A better user experience There are many ways to implement it, including using scroller, animation, and latency strategies. Using handler to achieve elastic sliding The effect can see the button buttons sliding. Note that this changes the contents of the view. You can try to remove the o

Dynamic combination column of EasyUI and elastic IRD Dojo, ExtJS, Jquery (EasyUI, jQgrid, ligerui, DWZ), server controls in asp.net, and the table tag of HTML tags are also indispensable. Among them, dojo, ExtJS, and Jquery should be considered a parallel relationship. They are all based on JavaScript frameworks, but the learning costs of dojo and ExtJS are higher than those of jquery, and the learning curve is steep, there are few Chinese documents,
