event.stoppropagation的兼容

Posted 2020-07-07

jquery的event.stoppropagation()是兼容firefox、chrome的，但不兼容ie

兼容写法：

        if (event.stopPropagation) {
            event.stopPropagation();
        }
        else if (window.event) {
            window.event.cancelBubble = true;
        }    

window.event在ie和chrome上是有的，firefox上没有window.event，需要函数中参数带入

    $(".dom").click(function (event) {
        if (event.stopPropagation) {
            event.stopPropagation();
        }
        else if (window.event) {
            window.event.cancelBubble = true;
        }
        ...
    });
