想实现点赞功能
main.jsp:
<html>
<body>
<%!int number;%>
<jsp:useBean id="simple" scope="application" class="shiyaner.Simple"/>
<a href="#" onclick="js_method();return false;">点赞+1</a>
|
点赞<%=simple.getCount()%>次
<script>
function js_method(){
<%number=simple.getCount();%>
<%simple.setCount(number++);%>
}
</script>
</body>
</html>
Simple.java:
package shiyaner;
public class Simple {
private int count;
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
}
simple.setCount(++number);
或者
simple.setCount(number+1);
<%number=simple.getCount();%>
而且这里不用<% %>
