[英]AJAX to Controller Password Confirmation
I am newer to both AJAX and MVC and I am trying to make a confirmation interaction. 我对AJAX和MVC都比较陌生,我正在尝试进行确认互动。
What I am trying to do is display a box, the user will enter a value and click submit, and then box will AJAX POST (I think that is what I am supposed to use) to the Controller and return a true or false. 我想做的是显示一个框,用户将输入一个值,然后单击Submit,然后该框将AJAX POST(我认为这是我应该使用的)发送到Controller并返回true或false。 I cannot seem to figure out how to make this interaction work however.
我似乎无法弄清楚如何使这种交互有效。
If I run debug I can see my value getting passed into the Controller, but it ignores my if
statement to check if the string was correct. 如果我运行调试,我可以看到我的值被传递到Controller中,但是它将忽略我的
if
语句来检查字符串是否正确。 Beyond that, I am not sure how to return a true/false and deal with it in my AJAX. 除此之外,我不确定如何在我的AJAX中返回true / false并进行处理。
Here is my "best guess" so far. 到目前为止,这是我的“最佳猜测”。
AJAX/JS AJAX / JS
<script type="text/javascript">
function preloadFunc() {
var prompting = prompt("Please enter your password", "****");
if (prompting != null && prompting != null) {
$.ajax({
url: '/Admin/magicCheck',
type: 'POST',
data: {
'magic': prompting
},
success: function () {
//let page load
},
error: function () {
preloadFunc(); //re-ask
}
});
}
else {
window.location.replace("google.com"); //Pressing Cancel
}
}
window.onpaint = preloadFunc();
</script>
Controller 调节器
[HttpPost]
public ActionResult magicCheck(string magic)
{
bool success = false;
if (magic == "poof")
{
success = true;
}
else
{
success = false;
}
return RedirectToAction("Index");
}
All help greatly appreciated as I am new to this! 感谢所有的帮助,因为我是新来的!
Read all the comments below your post as there are many issues here, but as far as comminication AJAX and returning: 阅读本文下方的所有评论,因为这里有很多问题,但要尽量减少AJAX和返回:
Change the controller to return JSON, like this: 更改控制器以返回JSON,如下所示:
[HttpPost]
public ActionResult magicCheck(string magic)
{
bool success = false;
if (magic == "poof")
{
success = true;
}
else
{
success = false;
}
return Json( new { Success = success });
}
Now that the controller is returning JSON you need to change your js to handle it: 现在控制器返回了JSON,您需要更改js来处理它:
$.ajax({
url: '/Admin/magicCheck',
type: 'POST',
data: 'magic=' + prompting, //<-- you didn't need to send JSON for this, you'd have to change your controller if you are going to send a JSON object also... you just need this for now
success: function (resp) {
//let page load
if ( resp.Success ){
// success...
}
else{
//fail
}
},
error: function () {
preloadFunc(); //re-ask
}
});
