is an example of a direct sticker:　　To illustrate the use of objects first, Box.childcontexttype is such a context declaration, when a child component calls the method of the ancestor component,by this.context.[ CALLBACK] This makes it possible to communicate between ancestors and sub-components. Summary: Today summarizes the concept of unidirectional data flow and the communication between components, I hope you can see the react some basic principles have a deeper understanding, there is a mi

NIC is also set to the mixed mode. The to_ms parameter specifies the timeout Control for read data. The timeout value is calculated in milliseconds. When there is no data on the internal network card during the timeout period, the read operation on the NIC will return (such as pcap_dispatch () or pcap_next_ex ). Also, if the network card is in statistical mode (see "Statistics and collection of network data streams") to_ms also defines the statistica

I believe many of my friends often use waterfall streams. however, we often encounter this problem. For example, the waterfall stream cannot be pulled down and refreshed, or pulled up more. Some are a simple touch event listener that pulls and loads more, but obviously, such features and user experience cannot be improved. so today, I took the time to develop the waterfall stream that can be pulled down and pulled down. I learned from the pull-down co

Step by step, gather small streams ------- js to implement the placeholder effect, placeholder. js I asked a question in the "Technical Q A" a few days ago, and then I wrote a reply to summarize the effect of placeholder. I have to say that if I know more, I can make it concise, describe the clearest expressions in the simplest language. However, placeholder is a newly added attribute of html5. its compatibility still has problems. After thinking ab

[Project 1 live broadcast]☞2. Pull live streams and broadcast ProjectsI. Introduction to video technology 1. Video is structured data. Data is transmitted during live broadcasting, which is a small unit of video. Video = image + audio The original image data in the video is usually compressed in H.264 encoding format. Audio sample data is usually compressed in AAC encoding format. 2. Real-Time Video Transmission Video is structured data, and live

position in the C language, and the name should be "bian "; after unpack is used, the name in php is "bian \ 0bian \ 0 ".At first, I used the strpos function to locate the "\ 0" position, and then intercepted the substr. But the Faint thing happened. I don't know whether it is the strpos bug or the substr bug (in fact, I will know it after testing). Some strings are okay, some strings can only get null values (that is, $ name = "). Very depressing. Later I found a strtok function, and there is
