vue实现ctrl+v黏贴上传图片
<div id="preview" class="click-to-upload" v-on:paste="handlePaste"> <span style="color:#999">将图片按Ctrl+V 粘贴至此处</span> </div>
// 监听粘贴操作 handlePaste (event) { const items = (event.clipboardData || window.clipboardData).items; let file = null; if (!items || items.length === 0) { this.$message.error("当前浏览器不支持本地"); return; } // 搜索剪切板items for (let i = 0; i < items.length; i++) { if (items[i].type.indexOf("image") !== -1) { file = items[i].getAsFile(); break; } } if (!file) { this.$message.error("粘贴内容非图片"); return; } // 此时file就是我们的剪切板中的图片对象 this.addFile(file)//预览 console.log("黏贴", file) },
addFile (file) { if (file.type.indexOf('image') >= 0) { var reader = new FileReader() var image = new Image() var _this = this reader.readAsDataURL(file) reader.onload = function () { file.src = this.result image.onload = function () { var width = image.width var height = image.height file.width = width file.height = height _this.imgList.push({ file }) } image.src = file.src //_this.$emit('base', file.src) let fileName = _this.guid() _this.fileSelect(file, _this.ossData.credentials, fileName)//上传到服务器 } } },
