比较全面的event对像在IE与FF中的区别 推荐_javascript技巧

May 16, 2016 pm 06:46 PM

window.event
IE:有window.event对象
FF:没有window.event对象。可以通过给函数的参数传递event对象。如onmousemove=doMouseMove(event)
鼠标当前坐标
IE:event.x和event.y。
FF:event.pageX和event.pageY。
通用:两者都有event.clientX和event.clientY属性。

鼠标当前坐标(加上滚动条滚过的距离)
IE:event.offsetX和event.offsetY。
FF:event.layerX和event.layerY。
标签的x和y的坐标位置:style.posLeft 和 style.posTop
IE:有。
FF:没有。
通用:object.offsetLeft 和 object.offsetTop。

窗体的高度和宽度
IE:document.body.offsetWidth和document.body.offsetHeight。注意:此时页面一定要有body标签。
FF:window.innerWidth和window.innerHegiht,以及document.documentElement.clientWidth和document.documentElement.clientHeight。
通用:document.body.clientWidth和document.body.clientHeight。

添加事件
IE:element.attachEvent(”onclick”, func);。
FF:element.addEventListener(”click”, func, true)。
通用:element.onclick=func。虽然都可以使用onclick事件,但是onclick和上面两种方法的效果是不一样的,onclick只有执行一个过程,而attachEvent和addEventListener执行的是一个过程列表,也就是多个过程。例如:element.attachEvent(”onclick”, func1);element.attachEvent(”onclick”, func2)这样func1和func2都会被执行。

标签的自定义属性
IE:如果给标签div1定义了一个属性value,可以div1.value和div1[”value”]取得该值。
FF:不能用div1.value和div1[”value”]取。
通用:div1.getAttribute(”value”)。

父节点、子节点和删除节点
IE:parentElement、parement.children,element.romoveNode(true)。
FF:parentNode、parentNode.childNodes,node.parentNode.removeChild(node)。
