vue代码
//获取元素距离页面边缘的距离 getOffset(box,direction){ var setDirection = (direction == 'top') ? 'offsetTop' : 'offsetLeft' ; var offset = box[setDirection]; var parentBox = box.offsetParent; while(parentBox){ offset+=parentBox[setDirection]; parentBox = parentBox.offsetParent; } parentBox = null; return parseInt(offset); }, moveCode(code,_this){ var fn = {codeVluae : code}; var box = document.querySelector("#code-box"), progress = box.querySelector("p"), codeInput = box.querySelector('.code-input'), evenBox = box.querySelector("span"); //默认事件 var boxEven = ['mousedown','mousemove','mouseup']; //改变手机端与pc事件类型 if(typeof document.ontouchstart == 'object'){ boxEven = ['touchstart','touchmove','touchend']; } var goX,offsetLeft,deviation,evenWidth,endX; function moveFn(e){ e.preventDefault(); e = (boxEven['0'] == 'touchstart') ? e.touches[0] : e || window.event; endX = e.clientX - goX; endX = (endX > 0) ? (endX > evenWidth) ? evenWidth : endX : 0; if(endX > evenWidth * 0.7){ progress.innerText = '松开验证'; progress.style.backgroundColor = "#66CC66"; }else{ progress.innerText = ''; progress.style.backgroundColor = "#FFFF99"; } progress.style.width = endX+deviation+'px'; evenBox.style.left = endX+'px'; } function removeFn() { document.removeEventListener(boxEven['2'],removeFn,false); document.removeEventListener(boxEven['1'],moveFn,false); if(endX > evenWidth * 0.7){ progress.innerText = '验证成功'; progress.style.width = evenWidth+deviation+'px'; evenBox.style.left = evenWidth+'px' codeInput.value = fn.codeVluae; evenBox.onmousedown = null; _this.ruleForm.verification = true; }else{ progress.style.width = '0px'; evenBox.style.left = '0px'; } }; function getOffset(box,direction){ var setDirection = (direction == 'top') ? 'offsetTop' : 'offsetLeft' ; var offset = box[setDirection]; var parentBox = box.offsetParent; while(parentBox){ offset+=parentBox[setDirection]; parentBox = parentBox.offsetParent; } parentBox = null; return parseInt(offset); }; evenBox.addEventListener(boxEven['0'], function(e) { e = (boxEven['0'] == 'touchstart') ? e.touches[0] : e || window.event; goX = e.clientX, offsetLeft = getOffset(box,'left'), deviation = this.clientWidth, evenWidth = box.clientWidth - deviation, endX; document.addEventListener(boxEven['1'],moveFn,false); document.addEventListener(boxEven['2'],removeFn,false); },false); fn.setCode = function(code){ if(code) fn.codeVluae = code; } fn.getCode = function(){ return fn.codeVluae; } fn.resetCode = function(){ evenBox.removeAttribute('style'); progress.removeAttribute('style'); codeInput.value = ''; }; return fn; }
调用
mounted(){ var _this = this; // window.addEventListener('load',function(){ //code是后台传入的验证字符串 var code = "jsaidaisd656", codeFn = new _this.moveCode(code,_this); // }); }
验证样式
.form-inline-input{ border:1px solid #dadada; border-radius:5px; } .form-inline-input input, .code-box{ padding: 0 3px; width: 298px; height: 40px; color: #fff; text-shadow: 1px 1px 1px black; background: #efefef; border: 0; border-radius: 5px; outline: none; } .code-box{ position: relative; } .code-box p, .code-box span{ display:block; position: absolute; left: 0; height: 40px; text-align: center; line-height: 40px; border-radius: 5px; padding:0; margin:0; } .code-box span{ width: 40px; background-color:#fff; font-size: 16px; cursor: pointer; margin-right:1px; } .code-box p{ width: 0; background-color: #FFFF99; overflow: hidden; text-indent: -20px; transition: background 1s ease-in; } .code-box .code-input{ display: none; } .code-box .code-input{ display: none; } .form-inline-input{ border:1px solid #dadada; border-radius:5px; } .form-inline-input input, .code-box{ padding: 0 3px; width: 298px; height: 40px; color: #fff; text-shadow: 1px 1px 1px black; background: #efefef; border: 0; border-radius: 5px; outline: none; } .code-box{ position: relative; } .code-box p, .code-box span{ display:block; position: absolute; left: 0; height: 40px; text-align: center; line-height: 40px; border-radius: 5px; padding:0; margin:0; } .code-box span{ width: 40px; background-color:#fff; font-size: 16px; cursor: pointer; margin-right:1px; } .code-box p{ width: 0; background-color: #FFFF99; overflow: hidden; text-indent: -20px; transition: background 1s ease-in; } .code-box .code-input{ display: none; } .code-box .code-input{ display: none; }
