Answer 1

您好，请使用此代码，这是在您点击网址后获取json中的数据这是jsonv.json文件，然后是validate（）函数

        var a = document.getElementById('a2')
        html2canvas(document.getElementById('a1'), {
            onrendered: function(canvas) {
            var img = canvas.toDataURL("image/jpeg");
            window.open(img);
                    }
        }

如果您已将数据存储在任何网址中，那么您可以发布ajax网址：''如果您想在打开新网页相同标签后登录成功，请使用_self

function  validate() {
 var jsdata;
$.ajax({
        type: "POST",
        url:"http://172.25.183.183:8080/JIRAservice/rest/login/", 
        dataType: "json",
        data: JSON.stringify({
            user_name: $("#input").val(), 
            password: $("#input1").val()
        }),
        success: function(response) {
            jsdata=response;
            var  un = document.loginscreen.uname.value;

            var  pw = document.loginscreen.psw.value; 

            if  ((un == jsdata.user_name) && (pw == jsdata.password)) {
                var myWindow = window.open("file:///C:/Users/KS5034674/Desktop/Gagile/WebContent/homescreen.html", "_self");
             return  true;

            } else  {

              console.log("login Failed");

            }
        },
        error: function(response) {
            console.log(response);
        }
}); 
}

如何在访问url时在控制台中获取响应（json格式）
