Ajax请求

AWS在JQuery ajax的基础上对常用的异步请求方法进行了封装，对Web开发者提供了4类常见异步请求方式，并对底层进行了统一的处理，如异常拦截。

• request
• load
• post
• get

方法说明：

示例代码

awsui.ajax.request 示例

awsui.ajax.request({
    type: "POST",
    url: "./jd?sid="+sid+"&cmd=%AppId%_calculation",
    data: "number1=15&number2=1032&sign=+",
    ok : function(r) {
        //请求处理成功
    },
    err : function(r){
        //请求处理错误
    }
});

awsui.ajax.load 示例

awsui.ajax.load("./jd?sid="+sid+"&cmd=%AppId%_calculation", { number1: 15, number2: 1032, sign: '+' }, function(data){
    awsui.ajax.alert(data, true, function(){ alert('callback'); });
});

awsui.ajax.post 示例

awsui.ajax.post("./jd?sid="+sid+"&cmd=%AppId%_calculation", { number1: 15, number2: 1032, sign: '+' }, function(data) {
    awsui.ajax.alert(data, true, function(){ alert('callback'); });
}, 'json');

awsui.ajax.get 示例

awsui.ajax.get("./jd?sid="+sid+"&cmd=%AppId%_calculation", { number1: 15, number2: 1032, sign: '+' }, function(data) {
    if(awsui.ajax.responseObject(data))
        awsui.ajax.alert(data, true, function(){ alert('callback'); });
}, 'json');

awsui.ajax.ok 示例

if(awsui.ajax.ok(data))
    alert(data['msg']);

awsui.ajax.responseObject 示例

if(awsui.ajax.responseObject(data))
    awsui.ajax.alert(data, true, function(){ alert('callback'); });

awsui.ajax.alert 示例

awsui.ajax.alert(data, true, function(){ alert('callback'); });

后端接参

/**
 * Ajax数值计算
 *
 * @param me 用户上下文
 * @param number1 数字1
 * @param number2 数字2
 * @param sign 运算符
 */
@Mapping("%AppId%_calulation")
public String calculation(UserContext me, int number1, int number2, String sign) {
    TestWeb web = new TestWeb(me);
    return web.calculation(number1, number2, sign);
}

View层逻辑处理

public class TestWeb extends ActionWeb {

    public TestWeb() {
    }

    public TestWeb(UserContext ctx) {
        super(ctx);
    }

    public String calculation(int number1, int number2, String sign) {
        ResponseObject ro = ResponseObject.newOkResponse();
        // 处理逻辑
        // ……
        // ro.put("newNum",newNum);
        return ro.toString();
    }
}
