点击users后，我想将一些数据加载到div Submit中。我为此目的使用ajax。问题是页面http://localhost:8080/myprj/showUsers在按钮点击事件时打开，而不是将此内容加载到div。
Context.jsp
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<html>
<head>
<script type="text/javascript">
function loadAjax() {
$.ajax({
url: "context.do",
success: function(result) {
$("#users").html(result);
},
error : function(e) {
alert('Error: ' + e);
}
});
}
</script>
</head>
<body>
<h2>Context information</h2>
<form:form method="POST" action="/myprj/showUsers">
<table>
<tr>
<td><form:label path="weather">Weather</form:label></td>
<td><form:input path="weather" /></td>
</tr>
<tr>
<td><form:label path="companions">Companions</form:label></td>
<td><form:input path="companions" /></td>
</tr>
</table>
<table border="1" cellspacing="1" align="center" style="margin-top: 160px;">
<tr>
<th>Weather</th>
<th>Companions</th>
</tr>
<tr>
<td>${weather}</td>
<td>${companions}</td>
</tr>
</table>
<input type="submit" value="Submit" onclick="loadData()" />
</form:form>
<div id = "users"></div>
</body>
</html>

@Controller
public class Test1 {
@RequestMapping(value = "/context", method = RequestMethod.GET)
public ModelAndView context() {
return new ModelAndView("context", "command", new Context());
}
@RequestMapping(value = "/showUsers", method = RequestMethod.POST)
public String showUsers(@ModelAttribute("SpringWeb")Context context, ModelMap model) {
model.addAttribute("weather", context.getWeather());
model.addAttribute("companions", context.getCompanions());
return "result";
}
}
答案 0 :(得分：0)
您的代码中没有第一个type="submit"功能。
由于以下原因，第二次使用button代替submit。
对于<input type="button" value="Submit" onclick="loadAjax()" />
当页面出现任何javascript错误时，除了记录错误之外，它不会执行任何操作。
