JavaScript通過表單值獲取請求

-1

有問題了解如何創建GET請求到另一個獲取該網站html內容的域。表單數據是使用的獲取請求的一部分。JavaScript通過表單值獲取請求

<form name="login"> 
    <div class="login"> 

    <input type="text" placeholder="User Name" name="userid"><br> 
    <input type="password" placeholder="Password" name="pswrd"><br> 
    <input type="fromdate" placeholder="From date" name="startdate"><br> 
    <input type="Todate" placeholder="To Date" name="todaysdate"><br> 
    <input type="button" onclick="check(this.form)" value="Check Data Usage"/> 

    </div> 

function check(form) 
{ 
    var request = new Request({ 
    url: '"http://dashboard.somesite.io/DashboardDataServices.asmx/GetMyUsage?userName="+form.userid.value+"&password="+form.userid.value+"&fromDate="+form.startdate.value+"&toDate="+form.todaysdate.value' 
method: 'GET' 
    }); 
    fetch(request); 
};

我得到的常見的問題：

Uncaught ReferenceError: check is not defined at HTMLInputElement.onclick

之間的JavaScript代碼參見本：https://developer.mozilla.org/en-US/docs/Web/API/Request –

函數'check'放在HTML中或者使用'

把<script>和</script>

<script> 
function check(form) 
{ 
    var request = new Request({ 
    url: '"http://dashboard.somesite.io/DashboardDataServices.asmx/GetMyUsage?userName="+form.userid.value+"&password="+form.userid.value+"&fromDate="+form.startdate.value+"&toDate="+form.todaysdate.value' 
method: 'GET' 
    }); 
    fetch(request); 
}; 
</script>
