This article mainly introduces jQuery's method of implementing full checkbox selection, involving jQuery's skills related to page element attributes and mouse event response, for more information, see the example in this article. Share it with you

Server-side method:Put a gridview control on the page, configure the data source, edit the column, add a template column, edit the template, and put it into a checkbox control. The Code is as follows:

The server can also select or cancel the checkbox on the page. However, I always feel that the efficiency is not high. It is better to use Js. JS is used without security...   Script Language = " Javascript " > Function

When selecting all, all individual checkboxes must be selected, which in turn can be implemented // Select all button $ ('chall '). addevent ('click', function () {$ $ ('input [name = "itemchk"] '). each (function (item) {if ($ ('chall ').

The success of the script is determined by the state that the server returns, and if the HTTP status returned by the server is OK, then vugen that the script is running correctly and that it is running. Returns the error page code when most system

buffer, the processing is complete. DBWR continues to write checkpoint buffers when there is an incomplete active checkpoint request.Algorithm Features:1) DBWR can know exactly which buffers to write for satisfying the checkpoint request;2) Ensure that the checkpoint that completes the oldest (with the lowest redo value) is guaranteed to be written at each checkpoint.3) You can differentiate multiple checkpoint requests based on the checkpoint redo values, and then complete the processing in th

Yesterday at the time of the test, it was found that a program written by a developer in the development library is good, but in the test library there will be a problem. Developers have been unable to find the cause of the problem. So it took some time to help developers find the root cause of the problem.By some technical means, locating the problem is caused by an SQL statement.The SQL statements are as follows:With Pxq_task_temp as(SELECT a.distribute_date,A.app_no,A.TASK_ID,A.task_no,A.actu

The main purpose of a checkpoint is to refresh dirty blocks in a way that has minimal impact on the daily operations of the database. Dirty blocks are constantly generated. How can I refresh the dirty blocks to the disk? Before 8i, Oracle regularly performs some modification operations on lock residences to refresh all dirty blocks in the Buffer cache. This method of refreshing dirty blocks is called a full checkpoint, which greatly affects the efficiency, after 9i, a full checkpoint occurs only

OverviewIn the "in-depth understanding of spark: core ideas and source analysis," a simple introduction of the next Rdd checkpoint, the book is a pity. So the purpose of this article is to check the gaps and improve the contents of this book.Spark's Rdd will save checkpoints after execution, so that when the entire job fails to run again, the successful RDD results have been run before recovery from the checkpoint, which will significantly reduce the

are only two redo log groups. The solution to this problem is to increase the redo log or add more redo log groups. No matter which solution, we aim to win more time for dbwn. ( Other explanations are as follows:When the system needs to reuse a log file, the system needs to write the dirty block in the buffer cache included in the log file to the corresponding data file. For a database operation, it may generate only dozens of bytes of Redo, but it is indeed a block (usually 8 K) in the buff

Before analyzing the implementation of linux2.4.x network security, introduce some important concepts included in it: NetFilter, iptables, match, Target, Nf_sockopt_ops, and the implementation of network security function points. A detailed explanation will be described in the following analysis. The first is NetFilter, which defines the checkpoints in the protocol stack and the data structures referenced on check
