之前別人都是用jq寫的，自己整理了一下開始使用

<el-form-item label="驗證"> <div class="form-inline-input"> <div class="code-box" id="code-box"> <input type="text" name="code" class="code-input" /> <p></p> <span>>>></span> </div> </div> </el-form-item>

vue程式碼

//獲取元素距離頁面邊緣的距離 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"); //預設事件 var boxEven = ['mousedown','mousemove','mouseup']; //改變手機端與pc事件型別 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 = '鬆開驗證'; 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 = '驗證成功'; 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;    }

呼叫

mounted(){ var _this = this; // window.addEventListener('load',function(){ //code是後臺傳入的驗證字串 var code = "jsaidaisd656", codeFn = new _this.moveCode(code,_this); // }); }
