struts.xml配置如下:
<package name="woniu" extends="struts-default" > <action name="getJSON" class="ajax.GetJSON">
<result name="success">/index.jsp</result>
</action>
</package><constant name="struts.ui.theme" value="simple"></constant>
</struts>
transferText.jsp
<script type="text/javascript" src="json2.js">
</script>
<script>
function ajaxTransferText(){
var BigText = document.getElementById("BigText").value;
var ajaxTransferObjectRef = new ajaxTransferObject("范方梅","范方梅密码",10,BigText);
var JSONString=JSON.stringify(ajaxTransferObjectRef);
var xmlHttp;
if(window.ActiveXObject){
xmlHttp= new ActiveXObject("Microsoft.XMLHTTP");
}else if(window.XMLHttpRequest){
xmlHttp =new XMLHttpRequest();
var urlString ="jsonString="+JSONString;
alert(urlString);
xmlHttp.open("POST","getJSON.action?timeStamp=" + new Date().getTime(),true);
xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
xmlHttp.send(urlString);
}
}
function ajaxTransferObject(username,password,age,BigText){
this.username=username;
this.password=password;
this.age=age;
this.BigText=BigText;
}
</script>
</head> <body>
<textarea name="textarea" id="BigText" rows="5" cols="45"></textarea>
<br />
<input type="button" value="test" onclick="ajaxTransferText()";/>
</body>GetJSON.java
package ajax;
import java.io.IOException;import com.opensymphony.xwork2.ActionSupport;import net.sf.json.JSONObject;public class GetJSON extends ActionSupport { private String jsonString; public String getJsonString() {
return jsonString;
} public void setJsonString(String jsonString) {
this.jsonString = jsonString;
}
public String execute(){
System.out.println(jsonString);
JSONObject json = JSONObject.fromObject(jsonString);
System.out.println("username="+json.get("username"));
System.out.println("password="+json.get("password"));
System.out.println("age="+json.get("age"));
System.out.println("BigText="+json.get("BigText"));
return "success";
}
}
效果图:初衷是想在文本框输入文字后,点击“text”按钮弹出javascript提示框,点击确定后,显示index.jsp页面,前面的要求都实现了,但就是显示index.jsp没有成功,不知问题出在哪了,还望各路英雄帮忙找找别扭啊
