index = TextUtils.indexOf(text, needle); // for example $$username$$ above
text.replace(index, index + needle.length(), replacement);

是什么原因以及如何解决这个问题。我试着阅读它，但大部分都没有，我知道GUID是全局唯一标识符。但问题究竟是为什么造成的？
答案 0 :(得分：1)
这一行：
$（ “通”）发生变化（passcor（））;
passcor（）返回true，然后传递给change（）函数。 change（）期待一个函数，而不是布尔值：https://api.jquery.com/change/
我的假设是你不想在传入之前调用该函数（删除（）括号）：
$（ “通”）发生变化（passcor）;
答案 1 :(得分：1)
passcor()称为
Password: <input class="pass" type="password" name="pwd" name="pass" onChange=passcor() required><span id="errmsg7"></span><br><br>
Confirm Password: <input class="cpass" type="password" name="cpass" onChange=passcor() required><span id="errmsg1"></span><br><br>
