Uncaught syntaxerror: Unexpected token)

The following code raises this exception:

<Div class = "hd_live_div left"> <a href = "javascript: void ()" onclick = "loadliveplayer ('ud ')" style = "width: 40px; "> UHD </a> <a href =" javascript: void () "onclick =" loadliveplayer ('hd') "style =" width: 40px; "> HD </a> <a href =" javascript: void () "onclick =" loadliveplayer ('sd') "style =" width: 40px; "> LD </a> </div>

Possible causes of this error:

1. The href property value is "javascript: void ()", and "0" is not added to the brackets"

The format of the void operator is as follows: 1. javascript: void (expression) 2. javascript: void expressionexpression is a standard JavaScript expression to be calculated. Parentheses outside the expression are optional, but it is a good habit to write them. (Implement version navigator 3.0) you use the void operator to specify the hyperlink. The expression is calculated, but no content is loaded in the current document.

<Div class = "hd_live_div left"> <a href = "javascript: void (0)" onclick = "loadliveplayer ('ud ')" style = "width: 40px; "> UHD </a> <a href =" javascript: void (0) "onclick =" loadliveplayer ('hd') "style =" width: 40px; "> HD </a> <a href =" javascript: void (0) "onclick =" loadliveplayer ('sd') "style =" width: 40px; "> LD </a> </div>

2. The onclick event processing function "loadliveplayer" does not add the return value. As a result, javascript: void (0) is executed and the value "Return false" should be added;
