Uncaught SyntaxError: Unexpected token ) when using void()

Question

I get this error and I\'ve managed to narrow it down to:

aaa

That

Answer 1

Is because void takes one argument. You want:

<a href="javascript:void(0);" onclick="myFunction();">aaa</a>

Answer 2

Use

<a href="javascript:void(0);" onclick="myFunction();">aaa</a>

void expects a parameter.

There's an interesting discussion on using void(0) or other techniques here.

Answer 3

void is an operator, not a function. It requires a single expression as its operand. () is not a valid expression. The correct syntax is:

<a href="javascript:void 0;" onclick="myFunction();">aaa</a>

You can put parentheses around 0, but they're not necessary, just as you don't need parentheses around 0 when writing 3 + 0.
