[Go]html page Call js file function error onclick is not defined processing method

There is always an error in handling the onclick function in the HTML tag today: uncaught Referenceerror:dosave is not defined (...)

Looking for a long while did not find the wrong, and finally found that I was wrong, the correct wording as follows:

Html:

[HTML]View plain copy

1. <input type="button" value="Login Now" onclick="Dosave ();" />

Js:

[JavaScript]View plain copy

1. Dosave = function () {
2. Alert ("Success!")  ");
3. }

The following two types of errors are generally fatal:

[JavaScript]View plain copy

1. function Dosave () {
2. Alert ("will error!!  ");
3. }

And

[JavaScript]View plain copy

1. var Dosave = function () {
2. Alert ("will error!!  ");
3. }

Why is this, because:

The HTML page calls the function in the JS file, which must be in the form of Dosave = function () {}, otherwise written, and the HTML page will not search for the function.
