" in the input boxWorkaround: The code can see that the assignment of this DOM element is done through the Val () function, so the value can be read by JS: $ ("input[name= ' name ']"). Val ();3. The hint box disappears in a few seconds (some prompt box will automatically close, and the DOM node does not exist, the positioning of such elements is more troublesome)Solution: It is best to view the source code, in the local environment to find the corresponding code block, modify this box disappears

Resolution: B. The requirements specification describes the functionality and performance that a software system must provide and the constraints it needs to consider, not only as a basis for system testing and user documentation, but also as a basis for planning, designing, and coding all sub-series projects. It should describe as fully as possible the expected external behavior of the system and the user's visual behavior. In addition to design and implementation limitations, the software Requ

1. A text file contains multiple lines, each with a URL. Compile the code to calculate the file name in the URL and the number of occurrences.A) the file name does not include domain name, path, and URL parameters, such as http://www.rs.com/n.op/q/rs? The file name in ID = 1 is Rs.B) some URLs may have no file names, for example, http://www.abc.com/. this type of stati
arc is that it is relatively simple to use, without having to think about memory issues and so on, in the MRC era you need to retain an object you want to keep, and nowIt's not necessary. Now the only thing to do is to point to the object with a pointer, and as long as the pointer is not empty, the object remains on the heap. When you point the pointer to a new value, the original object will be release once.The disadvantage of arc is that if a circular reference occurs, a memory leak is prone.

simply use an index instead of creating an iterator object. Linklist also creates objects for each inserted element, all of which you have to understand that it also brings additional overhead.Finally, in the book Practical Java, Peter Haggar suggests using a simple array instead of a vector or ArrayList. This is especially true for programs with high efficiency requirements. Because the use of arrays (array) avoids synchronization, additional method calls, and unnecessary reallocation of space
