Question

event.stopPropagation（）在Firefox浏览器中不起作用，但在谷歌浏览器或Internet Explorer或Opera中运行良好，点击btn_1时Firefox浏览器中的问题应该显示消息btn_1不显示div1 。还有其他功能或解决这个问题的方法吗？感激

Answer 1

您需要将event对象显式传递给回调函数。例如：

document.querySelector("body").onclick = function(e){
    console.log(e); // the current event
};

您正在利用Chrome将当前事件公开为全局on the window（即window.event或仅event）这一事实。 Firefox不会这样做 - other browsers也会受到影响。

Answer 2

在我的情况下，致电event.preventDefault()是可行的。

我有一个React应用，当时我在material-ui复选框的onclick处理程序中调用event.stopPropogation（），如下所示：

<StyledCheckBox
  icon={<CircleUnchecked />}
  checkedIcon={<CircleChecked />}
  checked={shipmentEditIds.includes(id)}
  onClick={event => {
    event.stopPropagation();
    setShipmentEditIds({ id });
  }}
/>

由于某种原因，仅在firefox浏览器中，这并没有阻止事件的传播。将event.preventDefault()添加到onClick处理程序后，它便解决了该问题。

我知道这不能为stopPropagation()为什么不能在Firebox浏览器中工作而提供答案，而只是分享对我有用的东西。

Answer 3

从onclick传递事件：

btn.onclick =  function(){delete_cooke1(this, event) ;} ;

并在event

中使用stopPropagation()参数

function delete_cooke1(mmm, e){
     e.stopPropagation();
     e.preventDefault(); // Add this line also
     var str =    mmm.id.toString() ;
     alert(str);
     return;
}

event.stopPropagation（）无法在firefox javascript中运行
