Question

在Angular中工作，我正在使用一个简单的AJAX程序从JSON文件中获取数据并将其作为表获取。我在HTML和JS文件的简单结构中尝试了我的代码，其工作正常，但该代码在Angular中不起作用，。附注：我使用资产中的JavaScript，因为我的打字稿不好。

// main.js file in assets/js/ folder
var xmlhttp, myObj, x, txt = "";
xmlhttp = new XMLHttpRequest;
xmlhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
        myObj = JSON.parse(this.responseText);
        txt += "<thead><tr>" +
                "<th>Id</th>" +
                "<th>Brand</th>" +
                "<th>Project Name</th>" +
                "<th>Location</th>" +
                "<th>Sector</th>" +
                "<th>Created By</th>" +
                "<th>Created On</th>" +
                "</tr></thead><tbody>";
        for (x=0; x<4 ; x++) {
            txt += "<tr><td>"+  
            myObj[x].id + "</td> <td>" +
            myObj[x].brand + "</td> <td>" +
            myObj[x].project_name + "</td> <td>" +
            myObj[x].location + "</td> <td>" +
            myObj[x].sector + "</td> <td>" +
            myObj[x].created_by + "</td> <td>" +
            myObj[x].created_on + '</td><td>'+ 
            "</td></tr>";
        }
        txt += " </tbody>"        
        document.getElementById("demo").innerHTML = txt;
    }
};
xmlhttp.open("POST", "../json/detail.json", true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send();

我的json文件如下：

    //detail.json file in assets/json/
        [
        {
            "id":"896",
            "brand":"a2",
            "project_name":"qwerty",
            "location":"pune",
            "sector":"4",
            "created_by":"M.S",
            "created_on":"2/4/19"
        },
        {
            "id":"02",
            "brand":"a3",
            "project_name":"bottle",
            "location":"mumbai",
            "sector":"5",
            "created_by":"C.S",
            "created_on":"24/4/19"
        },
        {
        "id":"03",
        "brand":"a4",
        "project_name":"tottles",
        "location":"kolkata",
        "sector":"6",
        "created_by":"P.S",
        "created_on":"9/12/19"
    },
    {
        "id":"09",
        "brand":"a6",
        "project_name":"Device 23",
        "location":"Delhi",
        "sector":"7",
        "created_by":"T.S",
        "created_on":"08/4/19"
    }
]

应该在

中获取JSON

<table id="demo"></table>

从Angular的Assets文件夹中使用ajax，但不起作用
