WML Basic Language
"P" element
Functions like HTML, but if you want to display text this is a must.
"Do" element
In fact, each WAP application must support the navigation bar. The value of the main type attribute of Do label is accept, which means that when you press the soft key A new option is added to the column
Table. The Label property specifies the text to display. There are also some options:
Go-Navigate to another card or plate. He needs the href attribute.
Prev-Navigate to the previous card
Refresh-Refreshes the display.
NoOp-None
Anchor
function is the same as <A> in HTML. The anchor link in WML has the same effect as do, and the only difference is that anchor is not displayed in the form of an option.
<anchor>
Go to Card 2
<go href= "#card2"/>
</anchor>
Variable
The WML binding variable is a bit different from HTML and JavaScript. The WML variable can be invoked not only by WMLScript, but also by the card directly to the WML
File. In other words, variables can be entered not only by the user, but also by the setvar element. Of course variables can be manipulated by scripts, but this is not necessarily
Of This point of view must be further emphasized and clarified. For example, you may need a card to get the user's name, and the next card will show "Hello, flying knife" and I
We can do this "hello,$ (FirstName)", a bit like PHP, is not, this in the traditional HTML is impossible!
Since the values of variables can be saved between the card, they are often used to save state information and support some complex, interactive WAP services. This method of a
The problem is that when the entire deck has to be referenced again, these states may not be synchronized with the user's browsing. So, some events and properties are used to capture these events
(Onenterofrward and Onenterbackward). Refreshes are used to update the card based on the values of some variables.
User input
Of course, to make your page more powerful, variables need to store (receive) the user's standard input. This is done through some HTML-like elements.
Input-much like HTML, the user enters through the keyboard of the phone. As you can imagine, this input is not as practical as the keyboard we use on the PC, so we should try to
By simplifying this type of input, it is possible to use the Select element as much as possible for the user to choose. The Name property is the variable, and the default value and size attribute are clearly also
Of The format specifies an input mask for the input entry. Others, please check other information, I will not tell each of them!
Select/option-a list of user options. It's also like HTML:
<select name= ' movie ' >
