JS tip: Uncaught SyntaxError:Unexpected token ) Error solution

This article describes the solution to the JS prompt: Uncaught SyntaxError:Unexpected token ) error. Share it for your reference, as follows:

Uncaught SyntaxError: Unexpected token )

The following code throws this exception:

&lt;div class="Hd_live_Sharediv left"&gt;
    &lt;a href="javascript:void()" onclick="loadLivePlayer('ud')" style="width:40px;"&gt;Ultra clear&lt;/a&gt;
    &lt;a href="javascript:void()" onclick="loadLivePlayer('hd')" style="width:40px;"&gt;HD&lt;/a&gt;
    &lt;a href="javascript:void()" onclick="loadLivePlayer('sd')" style="width:40px;"&gt;Smooth&lt;/a&gt;
&lt;/div&gt;

What may cause this error:

1. The href attribute value is "JavaScript:void()", and no "0" is added in the brackets.

The usage format of the void operator is as follows:

①. javascript:void (expression)
②. javascript:void expression

expression is a Javascript standard expression to be calculated. The brackets on the outside of the expression are selected, but writing them is a good habit. (Implementation version Navigator 3.0 )
You specify the hyperlink by using the void operator. The expression will be calculated but nothing is loaded in the current document.

&lt;div class="Hd_live_Sharediv left"&gt;
    &lt;a href="javascript:void(0)" onclick="loadLivePlayer('ud')" style="width:40px;"&gt;Ultra clear&lt;/a&gt;
    &lt;a href="javascript:void(0)" onclick="loadLivePlayer('hd')" style="width:40px;"&gt;HD&lt;/a&gt;
    &lt;a href="javascript:void(0)" onclick="loadLivePlayer('sd')" style="width:40px;"&gt;Smooth&lt;/a&gt;
&lt;/div&gt;

2. The onclick event handling function "loadLivePlayer" does not add the return value, resulting in javascript:void(0) being executed. You should add: return false;
