This article introduces the use of native JS for the implementation from a form checkbox to obtain the selected data value, the specific implementation of the following, interested friends can refer to ha, I hope to help you
Get the selected data
Get the selected data value from a form checkbox:
Copy Code code as follows:
aa

Using native JS writing:
Copy Code code as follows:

buffer ). Then, run the 'D' command to delete "foo" from the mode space so that it is not printed after all commands are executed on this line.
Now, the second line. After reading "bar" into the mode space, run the 'G' command to keep the content of the space ("foo \ n ") attaches to the mode space ("bar \ n"), so that the content of the mode space is "bar \ n \ foo \ n ". The 'H' command puts the content back to the reserved space for protection, and then, 'D' deletes the row from the mode spa

Gnucash is a lite version of Microsoft financial management software such as Microsoft Money and quicken, but it provides all the functions required by ordinary users for financial management. The gnucash user interface is incredibly concise-it looks more like a

Q: I used the Windows operating system for many years and now I want to switch to a Mac computer. But every article I read says that even with Windows-compliant software, Quicken can't run on Mac computers, at least not reliably, and I rely heavily on
$ (the entire current row). To print the length of each line in the file, use the following awk script:
{
print length ()
}
A financial anecdote.A few weeks ago, I decided to write my checkbook clearing procedure in awk. I decided to use a simple tab-bound text file to facilitate the entry of the most recent deposit and withdrawal records. The idea is to give this data to the awk script, which automatically aggregates all the

Windows Notepad-Kate or Gedit
The Linux (SuSE Linux) Running KDE Desktop contains a very useful Kate program. In The Gnome Environment (Ubuntu), you can use Gedit to replace Notepad perfectly.
Quicken-GnuCash
GnuCash may not be as mature as Quicken, but like Quicken, it can help you record all accounts and consumption, and it can also import
Java.lang.ClassLoader.loadClass (classloader.java:247)
And we see that the logic in line No. 238 above is actually instantiating an object and then doing a strong turn, and we'll look at the corresponding byte code:
0:aload_2
1:invokevirtual #164//Method java/lang/class.newinstance: () ljava/lang/object;
4:checkcast #168//class Groovy/lang/groovyobject
7:astore_3
In fact, it corresponds to such a few bytecode instructions, in fact, in the JVM when we execute the checkcast instruction will
It's a form. Today's form is obtained EventID from the table with the event delegate, and the first one executes in the form with a GET request to get the JSON data from the background, but after adding an event, the function of modifying (filling the data into the form) fails, then various reasons are found, When the newly added deleted after he can be implemented, but after the addition of information, with the alert test, his field to get normal, but the display returned to JSON, can not be e

. Most Web applications require some modification to run on the app engine.
The domestic Sina Network also reference Gae launched the Sina app Engine Open cloud computing platform, Sina App engine support PHP and MySQL, but database access, file operations, Web crawl, etc. need to use the API provided by Sina, can not use the original PHP function, Therefore, the existing PHP application also requires a certain modification to run on the SAE platform.

Multiple function Writing method is a process-oriented writing code implementation, adding a lot of global variables and not to reuse, you can not modify when others use, we may instead of using object-oriented approach to rewrite, we put the requirements of an object, this object is called a class, An important feature of object-oriented is encapsulation, which encapsulates properties and methods in an object, like placing items in a suitcase, so that it is c

These two ways are not mixed, otherwise the front will be covered, and we call just the

Here's a couple of object-oriented and process-oriented programming approaches. Page 10
Multiple function writing is a way to write code for the process of implementation, adding a lot of global variables and is not good for others to reuse, in others use you can not modify, we m
for us beginners, when using JS to create objects, do not adapt to the closure of the writing, often easy to forget to use the new keyword and make mistakes.
A closure is a function that has access to a variable in another function scope, that is, creating another function inside a function. We use this closure as the constructor for creating an object so that he can access the variable in the scope of the class function, such as the booknum variable, when it is both a closure and a function o
1, Basic introductionInheritance is an important feature of the class, and his presence makes it unnecessary to write repetitive code, which is highly reusable. Of course, the inheritance in OC and Java is the same, not much difference, here is looking at an example:First look at the parent class: CarCar.h1 #import2 3 @interfacecar:nsobject{4NSString *_brand;5NSString *_color;6 }7 8- (void) Setbrand: (NSString *) Brand;9- (void) SetColor: (NSString *) color;Ten- (void) Brake; One- (void)

Although it is widely believed that applications developed based on Windows platforms are suitable for running on Windows systems, some Linux users insist that, as long as they can do this on Windows, you can do better in Linux. Although there is some truth in this case, it is almost impossib

We create computers and communications technology to simplify our lives, don't we? Although the surface does not seem to be so--these technologies do bring some of its own complexity--but they do allow us to achieve something that we did not realize, in this sense, they really make people's lives simple and convenient.
For example, now you can walk from the breakfast table to the living room computer to see the current weather radar or road condition, or order a pot of new indoor plants, and of
