客户需求
用户在市场活动明细页面,输入备注内容,点击"保存"按钮,完成添加市场活动备注的功能.
*备注内容不能为空
*添加成功之后,清空输入框,刷新备注列表
*添加失败,提示信息,输入框不清空,列表也不刷新
功能开发知识点
1,添加市场活动备注：
? jsp的运行原理：
? xxx.jsp：1)、tocmat中运行：
????????????? 把xxx.jsp翻译成一个servlet,
?? ?????? 运行servlet,运行的结果是一个html网页
?? ?????? 把html网页输出到浏览器
?? ??? 2)、html网页在浏览器上运行：
?? ?????? 先从上到下加载html网页到浏览器，在加载过程中，运行前端代码
?? ?????? 当页面都加载完成，再执行入口函数.
2,把页面片段显示在动态显示在页面中：
? 选择器.html(htmlStr)：覆盖显示在标签的内部
? 选择器.text(htmlStr)：覆盖显示在标签的内部
? 选择器.append(htmlStr)：追加显示在指定标签的内部的后边
?? <div id="myDiv">
????? aaaaaaaaa
????? bbbbbbbbb
?? </div>
?? var htmlStr="<p>ccccccccc</p>";
??? $("#myDiv").append(htmlStr);
??? <div id="myDiv">
????? aaaaaaaaa
????? bbbbbbbbb
????? <p>ccccccccc</p>
?? </div>
? 选择器.after(htmlStr)：追加显示在指定标签的外部的后边
?? <div id="myDiv">
????? aaaaaaaaa
????? bbbbbbbbb
?? </div>
?? var htmlStr="<p>ccccccccc</p>";
??? $("#myDiv").after(htmlStr);
??? <div id="myDiv">
????? aaaaaaaaa
????? bbbbbbbbb
?? </div>
?? <p>ccccccccc</p>
?? 选择器.before(htmlStr)：追加显示在指定标签的外部的前边
?? <div id="myDiv">
????? aaaaaaaaa
????? bbbbbbbbb
?? </div>
?? var htmlStr="<p>ccccccccc</p>";
??? $("#myDiv").before(htmlStr);
??? <p>ccccccccc</p>
??? <div id="myDiv">
????? aaaaaaaaa
????? bbbbbbbbb
?? </div>
? ?
3,给元素扩展属性：html页面是可扩展的标记语言，可以给指定的标签任意扩展属性，只要属性名符合标识符的命名规则即可。
? 两个目的：
????? 1)使用标签保存数据：
??????? 如果是表单组件标签，优先使用value属性，只有value不方便使用时，使用自定义属性;
??????? 如果不是表单组件标签，不推荐使用value，推荐使用自定义属性。
????? 2)定位标签：
??????? 优先考虑id属性,其次考虑name属性，只有id和name属性都不方便使用时，才考虑使用自定义属性。
