这段JavaScript代码有什么问题？ [英] What's wrong in this JavaScript code?

问题描述

标记：

 <形式> 
< fieldset>< p> 
< label>用户名：< input type =textname =userid =user/>< / label>< / p>< br />< p> ; 
< label>密码：< input type =passwordname =passwid =passw/>< / label>< / p> 
< label>< input type =submitvalue =登录name =submitBUTstyle =width：65px; height：25px; background-color：green; color：white; font-重量：粗体; id =submitBUT/>< div id =helllo>< / div>< / label> 
< / fieldset> 
< / form> 
  

代码：

  var subBut = document.getElementById（'submitBUT'）; 
 var users = ['hithere'，'Peter112'，'Geksj'，'lOsja'，'fInduS'，'323DssaAA'，'f1fsus']; 
 var passes = ['mllesl'，'Petboy'，'Heneeesh'，'Olga'，'234dasdf77 /'，'minls'，'ew832ja']; 
 var output = []; 
函数submi（u，p）{
 for（var i = 0; i< users.length; i ++）{
 if（users [i] == u）{
 output.push（i）; 
 
 
 for（var o = 0; o< output.length; o ++）{
 if（passes [output [o]] == p）{
返回p +'是一个正确的密码。'; 
} 
} 
返回'错误，请重试'; 
} 
 subBut.onclick =（document.getElementById（'helllo'）。innerHTML =（submi（document.getElementById（'user'）。value，document.getElementById（'passw'）。value） ））;

是的，我知道你不会在源代码中存储密码：D，它只是毛皮t3h lulz

解决方案

我必须同意上面的评论，不知道你在做什么，但是......问题在于 submit 处理程序是一个函数而不是字符串：
$ b

  subBut.onclick =（document.getElementById ''）。innerHTML =（submi（document.getElementById（'user'）。value，document.getElementById（'passw'）。value）））; 
  

应该是：

  subBut.onclick = function（）{
 document.getElementById（'helllo'）。innerHTML = 
 submi（document.getElementById（'user'）.value，document.getElementById 'PASSW'）值）; 
返回false; //用于测试，防止表单提交
}; 
  

您可以在这里测试更新版本。

I can't figure it out..

Markup:

<form>
    <fieldset><p>
        <label>Username: <input type="text" name="user" id="user" /></label></p><br /><p>
        <label>Password: <input type="password" name="passw" id ="passw" /></label></p>
        <label><input type="submit" value="Log in" name="submitBUT" style="width: 65px; height: 25px; background-color: green; color: white; font-weight: bold;" id="submitBUT" /><div id="helllo"></div></label>
    </fieldset>
</form>

Code:

var subBut = document.getElementById('submitBUT');
var users = ['hithere', 'Peter112', 'Geksj', 'lOsja', 'fInduS', '323DssaAA', 'f1fsus'];
var passes = ['mllesl', 'Petboy', 'Heneeesh', 'Olga', '234dasdf77/', 'minls', 'ew832ja'];
var output = [];
function submi(u, p) {
    for (var i = 0; i < users.length; i++) {
        if (users[i] == u) {
            output.push(i);
        }
    }
    for (var o = 0; o < output.length; o++) {
        if (passes[output[o]] == p) {
            return p + ' was a correct password.';
        }
    }
    return 'Error, please try again';
}
subBut.onclick = (document.getElementById('helllo').innerHTML=(submi(document.getElementById('user').value, document.getElementById('passw').value)));

and yes, I know you don't store passwords in the source code :D, it's just "fur t3h lulz"

解决方案

I have to agree with comments above, not sure what you're doing but...the problem is that a submit handler is a function not the string you're assigning, this:

subBut.onclick = (document.getElementById('helllo').innerHTML=(submi(document.getElementById('user').value, document.getElementById('passw').value)));

should be:

subBut.onclick = function() { 
  document.getElementById('helllo').innerHTML=
    submi(document.getElementById('user').value, document.getElementById('passw').value);
  return false; //for testing, prevent form submission
}; 

You can test the updated version here.
