When defining a function with function name() {...} , if you are already inside a function, then it will only be defined in that function. 当使用function name() {...}定义函数时，如果您已经在函数内部，则只能在该函数中进行定义。
Function definitions should not be wrapped in a .ready() , since they don't run until they are called. 函数定义不应包装在.ready() ，因为它们在被调用之前不会运行。 Remove the .ready() wrapper and you should be good to go. 删除.ready()包装器，您应该一切顺利。

The following notation: 以下表示法：
$(function() { ... });
itself is a function that binds function() {...} to document.ready . 本身是一个将function() {...}绑定到document.ready function() {...} 。 And running function adminDBDisplay(db){...} in document.ready only defines the function it at runtime, but doesn't actually call it. 在document.ready运行函数adminDBDisplay(db){...}仅在运行时定义该函数，而实际上并未调用它。 In order to call it, you would want adminDBDisplay('parameter'); 为了调用它，您需要adminDBDisplay('parameter');
To effectively implement it, you'll want to place it within the body of your page as follows: 为了有效地实现它，您需要按如下所示将其放置在页面的正文中：
<head>
<script src="yourversionofjquery.js"></script>
<script>
//Defining your function for calling later
function adminDBDisplay(db)
{
alert("Got into function" +db);
//Planning to use Jquery Ajax here
}
</script>
</head>
<body>
<script>
//Binding an anonymous function to document.ready
$(function () {
//Do whatever you want after document.ready
});
</script>
<div> rest of body</div>
</body>
Let me know if that makes sense/fixes your errors. 让我知道这是否有意义/修复了您的错误。
EDIT: also, put 'single quote' around 'ownorg', like "adminDBDisplay('ownorg');" 编辑：同样，在“ ownorg”周围加上“单引号”，例如“ adminDBDisplay（'ownorg'）;” otherwise it's looking for a variable called ownorg. 否则，它正在寻找一个名为ownorg的变量。
