Void is a javascript operator that only executes expressions but does not return values,
The format of the void operator is as follows:
1. javascript: void (expression)
2. javascript: void expression
We recommend that you use the second type with parentheses for a good program style.
We can use the void operator to specify the hyperlink, such as javascript: void (document. form. submit ()). The expression is calculated, but no content is loaded in the current document. void (0) is calculated as 0, but it has no effect on JavaScript, that is, the same effect.
The effect is the same.
The key is as long as you know that void is the operator of javascipt itself, it indicates that only expressions are executed, but no return value is returned! In addition, the page is automatically adjusted back to the top because "#" is the top position by default, so this situation occurs.
