html 鼠标滚轮实现横向滚动

通过此函数可以获取到鼠标滚动事件，然后做平移就好了

/** Event handler for mouse wheel event.

*鼠标滚动事件

*/

var wheel = function(event) {

var delta = 0

if (!event) /* For IE. */

event = window.event

if (event.wheelDelta) { /* IE/Opera. */

delta = event.wheelDelta / 120

} else if (event.detail) {

/** Mozilla case. */

/** In Mozilla, sign of delta is different than in IE.

* Also, delta is multiple of 3.

*/

delta = -event.detail / 3

}

/** If delta is nonzero, handle it.

* Basically, delta is now positive if wheel was scrolled up,

* and negative, if wheel was scrolled down.

*/

if (delta)

handle(delta)

/** Prevent default actions caused by mouse wheel.

* That might be ugly, but we handle scrolls somehow

* anyway, so don't bother here..

*/

if (event.preventDefault)

event.preventDefault()

event.returnValue = false

}

/** Initialization code.

* If you use your own event management code, change it as required.

*/

if (window.addEventListener) {

/** DOMMouseScroll is for mozilla. */

window.addEventListener('DOMMouseScroll', wheel, false)

}

/** IE/Opera. */

window.onmousewheel = document.onmousewheel = wheel

/** This is high-level function.

* It must react to delta being more/less than zero.

*/

var handle = function(delta) {

var random_num = Math.floor((Math.random() * 100) + 50)

if (delta <0) {

// alert("鼠标滑轮向下滚动：" + delta + "次！")// 1

$("btn_next_pic").onclick(random_num)

return

} else {

// alert("鼠标滑轮向上滚动：" + delta + "次！")// -1

$("btn_last_pic").onclick(random_num)

return

}

}

在网页开发中，有些时候我们不想让用户去复制或者粘贴该网页的东西，那么下面的几个方法就非常有用了！

//屏蔽右键菜单

document.oncontextmenu = function (event){

    if(window.event){

        event = window.event

    }try{

        var the = event.srcElement

        if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){

            return false

        }

        return true

    }catch (e){

        return false

    }

} //屏蔽粘贴

document.onpaste = function (event){

    if(window.event){

        event = window.event

    }try{

        var the = event.srcElement

        if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){

            return false

        }

        return true

    }catch (e){

        return false

    }

} //屏蔽复制

document.oncopy = function (event){

    if(window.event){

        event = window.event

    }try{

        var the = event.srcElement

        if(!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){

            return false

        }

        return true

    }catch (e){

        return false

    }

} //屏蔽剪切

document.oncut = function (event){

    if(window.event){

        event = window.event

    }try{

        var the = event.srcElement

        if(!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){

            return false

        }

        return true

    }catch (e){

        return false

    }

} //屏蔽选中

document.onselectstart = function (event){

    if(window.event){

        event = window.event

    }try{

        var the = event.srcElement

        if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")){

            return false

        }

        return true

    } catch (e) {

        return false

    }

}

网页退出提示的方法：

window.onbeforeunload = function(event){

            event = event || window.event

            event.returnValue = ' '

    }

移动端中，屏蔽类似iphone的默认滑动事件用一下方法：

//禁用浏览器的默认滑动事件

    var preventBehavior = function(e) {

        e.preventDefault()

    }

    // Enable fixed positioning

    document.addEventListener("touchmove", preventBehavior, false)

您好！很高兴为您答疑！

拼写错误 event.preventDefatult()应该是event.preventDefault() 可以完美运行！
