<h1>The stopPropagation() Method</h1>
<p>Click DIV 1:</p>
<div onclick="func2()">DIV 2
<div onclick="func1(event)">DIV 1</div>
</div>
Stop propagation:
<input type="checkbox" id="check">
<p></p>
<p>因为 DIV 1 位于 Div 2 内，所以当您单击 DIV 1 时，两个 DIV 都会被单击。</p>
<p>选中这个停止传播复选框，然后重试。</p>
<p>stopPropagation() 方法允许您阻止当前事件的传播。</p>
<script>
function func1(event) { alert("DIV 1"); if (document.getElementById("check").checked) { event.stopPropagation();
}
}
function func2() { alert("DIV 2");}
