When using JS, when the same event is defined for the child element and parent element, such as the onclick event is defined, and when the child element is clicked, the OnClick event of the parent element is also triggered. JS says the mechanism for this event to occur continuously is event bubbling or event capture.Why are there events bubbling and catching? For the first time, IE browser and Natscape browser to their own browser of the event adopted a different mechanism,IE browser used bubble

Capturing the network package of a mobile phone is something that programmers often need to do. But the path to packet capture is not that smooth. Three tools are required for network packet capture on the mobile phone: 1.ADB: usually get from AndroidSDK. 2. root tool: psneuter3.tcpdump: The network packet capture tool wants to

Now that we know how to get the information of the adapter, let's start a more meaningful task, open the adapter and capture packets. In this lecture, We will compileProgramTo print out each data packet through the adapter.
The function to open a device is pcap_open (). Below are the parametersSnaplen,FlagsAndTo_msDescription:

We often catch a lot of data in Wireshark, and then we need to filter the filter to select the packets we care about.The Wireshark provides two types of filters:
Capture Filter: Set the filter condition before grabbing the packet, and then crawl only the qualifying packets.
Display filters: Sets the filter condition in the captured packet collection, hides the packets that you do not want to display, and displays only the eligible packets
