無法使用json數據

-1

我正在使用PHP腳本來生成JSON字符串，我想在javascript中使用它來顯示一些數據。問題是，即使在使用json.parse之後，我也無法訪問json字符串數據。請幫助我。無法使用json數據

JSON字符串是：

{ 
    "8": { 
     "dept_name": null, 
     "dept_code": null, 
     "int_jour": null, 
     "nat_jour": null, 
     "inter_nat_conf": null, 
     "nat_conf": null, 
     "int_book_chap": null, 
     "nat_book_chap": null 
    }, 
    "0": { 
     "int_jour": 10, 
     "nat_jour": 1, 
     "inter_nat_conf": 16, 
     "nat_conf": 14, 
     "int_book_chap": 1, 
     "nat_book_chap": 4, 
     "dept_code": "101", 
     "dept_name": "ECE" 
    }, 
    "1": { 
     "int_jour": 22, 
     "nat_jour": 1, 
     "inter_nat_conf": 32, 
     "nat_conf": 16, 
     "int_book_chap": 5, 
     "nat_book_chap": 0, 
     "dept_code": "102", 
     "dept_name": "CSE" 
    }, 
    "2": { 
     "int_jour": 12, 
     "nat_jour": 4, 
     "inter_nat_conf": 10, 
     "nat_conf": 23, 
     "int_book_chap": 1, 
     "nat_book_chap": 0, 
     "dept_code": "103", 
     "dept_name": "IT" 
    }, 
    "3": { 
     "int_jour": 21, 
     "nat_jour": 0, 
     "inter_nat_conf": 9, 
     "nat_conf": 35, 
     "int_book_chap": 0, 
     "nat_book_chap": 0, 
     "dept_code": "104", 
     "dept_name": "EE" 
    }, 
    "4": { 
     "int_jour": 13, 
     "nat_jour": 1, 
     "inter_nat_conf": 8, 
     "nat_conf": 33, 
     "int_book_chap": 0, 
     "nat_book_chap": 1, 
     "dept_code": "105", 
     "dept_name": "MCA" 
    }, 
    "5": { 
     "int_jour": 10, 
     "nat_jour": 5, 
     "inter_nat_conf": 12, 
     "nat_conf": 13, 
     "int_book_chap": 0, 
     "nat_book_chap": 1, 
     "dept_code": "106", 
     "dept_name": "MBA" 
    }, 
    "6": { 
     "int_jour": 57, 
     "nat_jour": 6, 
     "inter_nat_conf": 5, 
     "nat_conf": 10, 
     "int_book_chap": 0, 
     "nat_book_chap": 1, 
     "dept_code": "109", 
     "dept_name": "AS" 
    }, 
    "7": { 
     "int_jour": 0, 
     "nat_jour": 0, 
     "inter_nat_conf": 0, 
     "nat_conf": 0, 
     "int_book_chap": 0, 
     "nat_book_chap": 0, 
     "dept_code": "110", 
     "dept_name": "CIVIL" 
    } 
}

的JavaScript是：

<script> 

var xmlhttp = new XMLHttpRequest(); 

xmlhttp.onreadystatechange = function() { 
    if (this.readyState == 4 && this.status == 200) { 
     myObj = JSON.parse(this.responseText); 
     document.getElementById("demo").innerHTML = myObj.[1].dept_name; 

    } 
}; 
xmlhttp.open("GET", "sss.php", true); 
xmlhttp.send(); 

</script>

你會得到什麼錯誤？ –

打開瀏覽器的開發者工具。看看控制檯。閱讀錯誤消息。

Uncaught SyntaxError: Unexpected token [

您有：

document.getElementById("demo").innerHTML = myObj.[1].dept_name;

您可以使用點符號或方括號訪問屬性。你不能同時使用兩者。

在[之前刪除.。
