This is effective if the "behaviour" was "click".
This target is only all associated tips.
var closeTipTestObject = new jqTooltip({
selector: "p.closeTipTest",
behavior: "click"
});
<p class="closeTipTest" title="closeTipTest">Click here to launch tooltip.</p>
<p>
<a href="javascript:void(0)" onclick="closeTipTestObject.closeAllTips()">
Click here to close tooltip.
</a>
