wap手机网站开发过程中的小例子

来源：互联网发布：大疆osmo软件编辑：程序博客网时间：2024/05/17 02:24

听说wmlscript和javascript差不多，我想知道他是怎么声明的，javascript得写在<script></script>，不知道wmlscript是怎么写的，如果我要写成像javascript那种js脚本，我又应该怎么声明呢，哪位大哥能不能帮我写个最简单的例子，回答得好我会提高分数的！！！多谢了！
问题补充：<go href="validator.wmls#validate()"/>用这个我的会出现下载文件的对话框呀，不知道是怎么回事呀！，能不能再完整点,我用的是opera7模拟器，在wml文件中是不是要把那个wmls文件引用进来呀，就这里不会写呀！

m3gate安装目录下有例子，你可以看看
--------------calc.wmls代码如下------------------

再给你一个学习的网站
http://www.w3school.com.cn/wmlscript/index.asp

比如：wmlscript 定义在 *.wmls文件中。
然后在xml文件中调用是这样的
<go href="validator.wmls#validate()"/>
