What is an appropriate method to perform a native click in Chrome and Opera?

 Hi,

I have an issue with native click in Chrome and Opera. I have the below line of code in my script which retuens an anchor link

entityObj.childNodes[0].childNodes[0] - This returns an object with below properties

outerHTML - <a href="javascript&colon;void(0)" class="eqjs-ep-entity-node-button" savedtabindex="[object Object]" tabindex="-1"></a>

tagName - A

href - javascript&colon;void(0)

When I try to execute the code "entityObj.childNodes[0].childNodes[0].Click()"

In IE and Firefox

entityObj.childNodes[0].childNodes[0].Click() = Trigger the click event properly

In Chrome and Opera

entityObj.childNodes[0].childNodes[0].Click() = Object doesn't support this property or method

Any one suggest a right Click() method which will work in Chrome and Opera? 

See the attached object browser screenshot.
