本文为大家分享了一个简单的鼠标模拟案例,供大家参考,具体实现内容如下
如何实现捕抓鼠标事件,当鼠标滑动时,获取当前鼠标的坐标,接着在一个透明区域里绑定捕抓的位移,这样就能在模拟的透明区域里实现鼠标滑动的模型。
效果图:
HTML代码:

JS代码:var koringz = (function(){ var x, y, getmain, getcontent, getbox, getblock, getblock_case, getnav_top, block_case_margin_top, block_case_margin_left, block_casetostring1, block_casetostring2, block_casesubstring1, block_casesubstring2, istouch; getmain = document.querySelector('.main'); getcontent = getmain.querySelector('.content'); getbox = getcontent.querySelector('.box'); getblock = getcontent.querySelector('.block'); getblock_case = getblock.querySelector('.block_case'); getnav_top = getcontent.querySelector('.content-nav-top'); getnav_left = getcontent.querySelector('.content-nav-left'); function get_box() { w_getbox_distance = getbox.offsetWidth; h_getbox_distance = getbox.offsetHeight; istouch = 'ontouchstart' in window; getbox.addEventListener(istouch"rgba(147, 106, 77,1)"; } } (function (){ window.onload = function(){ move_box(); get_box() } })() var click =function () { this.borderradius = function(num) { if(typeof num == 'number'){ if(num == 0){ getblock_case.style.borderRadius = num; } else if(num > 0){ getblock_case.style.borderRadius = num +'%'; } else{ return false; } } } this.opacitas = function (num) { if(typeof num == 'number'){ getblock_case.style.opacity = num; } else{ return false; } } } var Click = new click(); return { createclick1 :Click.borderradius, createclick2 :Click.opacitas } })()这里的鼠标箭头也可换成自己喜欢的图标,模拟鼠标区域的颜色也可自由变换,模拟区域的效果也可是点状的,也可以是线状的,动画效果等等,这个自由发挥吧。
以上就是针对JavaScript鼠标响应事件进行的详细介绍,希望对大家的学习有所帮助。
