el-dialog实现拖拉，每次点击度居中显示，以下贴出代码具体实现，我是可以正常拖拉并且每次度显示在中间，效果还可以，需要的可以丢上去跑跑
组件部分：
<el-dialog:visible.sync="dialogVisible":close-on-click-modal="false"custom-class="draggable-dialog"ref="dialog"@open="onDialogOpen"@opened="onDialogOpened"@close="onDialogClose"width="646px"><div slot="title" class="header" @mousedown="startDrag"><span>公式设置</span></div><el-divider></el-divider><div >这里写你的dialog业务代码</div></el-dialog>定义变量：
函数部分：
startDrag(event) {event.preventDefault();this.dragging = true;this.startX = event.clientX;this.startY = event.clientY;const dialogRef = this.$refs.dialog.$el;if (!dialogRef) {console.error('无法找到对话框引用');return;}console.log('获取打开后的位置dialogRef-->',dialogRef);console.log('获取打开后的位置dialogRef.style.left-->',dialogRef.style.left);console.log('获取打开后的位置dialogRef.style.top-->',dialogRef.style.left);// 获取当前对话框的位置const style = window.getComputedStyle(dialogRef);this.currentX = parseFloat(style.left || '0');this.currentY = parseFloat(style.top || '0');console.log('this.currentX---------->',this.currentX);console.log('this.currentY---------->',this.currentY);document.onmousemove = this.doDrag.bind(this);document.onmouseup = this.stopDrag.bind(this);},doDrag(event) {if (!this.dragging) return;const deltaX = event.clientX - this.startX;const deltaY = event.clientY - this.startY;// 更新当前位置this.currentX += deltaX;this.currentY += deltaY;// 更新起始点this.startX = event.clientX;this.startY = event.clientY;const dialogRef = this.$refs.dialog.$el;if (dialogRef) {dialogRef.style.left = `${this.currentX}px`;dialogRef.style.top = `${this.currentY}px`;event.preventDefault();}},stopDrag() {this.dragging = false;document.onmousemove = null;document.onmouseup = null;},onDialogOpen() {// 对话框即将打开时，重置位置数据this.currentX = 0;this.currentY = 0;},onDialogOpened() {},onDialogClose() {// 对话框关闭时，取消所有事件监听器document.onmousemove = null;document.onmouseup = null;const dialogRef = this.$refs.dialog.$el;dialogRef.style.left= 0;dialogRef.style.top = 0;},CSS部分：
<style scoped>/**以下是dialog */
.draggable-dialog {position: fixed !important; /* �保对话框是固定定位 */top: 50%;left: 50%;transform: translate(-50%, -50%);transition: all .3s ease;overflow: auto; /* �保对话框内部可以滚动 *//*width: 600px; �定宽度 *//* height: 900px; /* �定高度 */
}
.header {cursor: move;
}
</style>
