When i am passing a variable to AJAX it works if i just create a variable with some string values e.g. var userid = "test" and var passwd = "test1" but not when the variable contains var userid = form.userid.value and var passwd = form.passwrd.value. Why does form.userid.value and form.passwrd.value not work?
当我将变量传递给AJAX时，如果我只是创建一个带有一些字符串值的变量，那么它就可以工作。 var userid =“test”和var passwd =“test1”但不是当变量包含var userid = form.userid.value和var passwd = form.passwrd.value时。为什么form.userid.value和form.passwrd.value不起作用？
Here is the HTML:
这是HTML：
<html>
<head>
<title>
Login page
</title>
<script src="login.js"></script>
<!-- jQuery -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<!-- jQuery -->
<script src="./jquery.rest.min.js"></script>
<script src="./webtoolkit.base64.js"></script>
</head>
<body>
<h1 style="font-family:Comic Sans Ms;text-align="center";font-size:20pt;
color:#00FF00;>
Simple Login Page
</h1>
<form name="login">
Username<input type="text" name="userid"/>
Password<input type="password" name="pswrd"/>
<input type="button" onclick="checkLogin(this.form)" value="Login"/>
<input type="reset" value="Cancel"/>
</form>
</body>
</html>
Here is the javascript which does not work (login.js):
这是javascript不起作用（login.js）：
function checkLogin(form) {
var auth_token = localStorage.getItem("token");
//the variables which do not correctly pass through to AJAX call
var userid = form.userid.value;
var passwd = form.pswrd.value;
if(auth_token == null) {
$.ajax({
type: 'POST',
data: {
username: userid,
password: passwd
},
url: 'http://127.0.0.1:8000/api/v1/api-token-auth/',
success: function(res){
var tok = res.token
localStorage.setItem("token", JSON.stringify(tok));
}});
} else {
$.ajax({
type: 'POST',
headers: {
'Authorization':'token ' + JSON.parse(auth_token)
},
data: {
quote_text: "Test Javascript with variable token pt 2",
tags: '["test", "javascript"]'
},
url: 'http://127.0.0.1:8000/api/v1/test/',
success: function(res){
console.log(res) //answer of api call.
}
});
};
};
However this will work where i have hard coded the username and password (login.js):
但是，这将在我硬编码用户名和密码（login.js）的地方工作：
function checkLogin(form) {
var auth_token = localStorage.getItem("token");
//hard coded variable content which works.
var userid = "test";
var passwd = "test1";
if(auth_token == null) {
$.ajax({
type: 'POST',
data: {
username: userid,
password: passwd
},
url: 'http://127.0.0.1:8000/api/v1/api-token-auth/',
success: function(res){
var tok = res.token
localStorage.setItem("token", JSON.stringify(tok));
}});
} else {
$.ajax({
type: 'POST',
headers: {
'Authorization':'token ' + JSON.parse(auth_token)
},
data: {
quote_text: "Test Javascript with variable token pt 2",
tags: '["test", "javascript"]'
},
url: 'http://127.0.0.1:8000/api/v1/test/',
success: function(res){
console.log(res) //answer of api call.
}
});
};
};
