我有以下代码：
<template>
<div class="chart"
v-bind:style="chartStyleObject"
v-on:mousedown.left="initHandleMousedown($event)"
v-on:mouseup.left="initHandleMouseup()"
v-on:mouseout="initHandleMouseup()">
<div class="chartContent">
</div>
<!-- <div class="chartContent"> end -->
</div>
<!-- <div class="chart"> end -->
</template>
<script>
import axios from 'axios';
export default{
created () {
},
data () {
return {
ticket: null,
chartStyleObject: {
width: '500px',
widthWrapper: '1600px',
heightWrapper: '500px',
height: '247px',
marginTop: '15px',
marginRight: '0px',
marginBottom: '0px',
marginLeft: '15px',
},
XCoord: null,
YCoord: null,
}
},
methods: {
initHandleMousedown(event) {
this.startMousedownXCoord = event.clientX;
this.startMousedownYCoord = event.clientY;
this.XCoord = event.clientX;
this.YCoord = event.clientY;
console.log('XCoord', this.XCoord);
console.log('YCoord', this.YCoord);
window.addEventListener('mousemove', this.initHandleMouseMove);
},
initHandleMouseMove(event) {
this.XCoord = event.clientX;
this.YCoord = event.clientY;
console.log('XCoord', this.XCoord);
console.log('YCoord', this.YCoord);
},
initHandleMouseup() {
window.removeEventListener('mousemove', this.initHandleMouseMove);
},
},
}
</script>
<style scoped>
.chart{
position: relative;
border-radius: 10px;
padding: 27px 10px 10px 10px;
background-color: #45788b;
box-sizing: border-box;
cursor: move;
}
.chart .chartContent{
position: relative;
top: 0;
left: 0;
height: 100%;
width: 100%;
margin: 0 0 0 0;
background-color: #2f2c8b;
}
</style>HTML design consists of 2 blocks:
(parent and child)
The event is tied to the parent tag `<div class =" chart ">`
Also, the parent block has padding on all 4 sides:
如果单击父块并用鼠标驱动（按住按钮）而不影响填充空间，则将触发mousemove事件而不会出现问题。但是，一旦鼠标光标触摸了填充区域，事件就会停止起作用。
如果单击填充，事件也将正常运行-但是，如果我将鼠标光标移到填充外部（内部空间）之外的块空间上，该事件将停止工作。
问题：
为什么会发生这种情况-对于js + nuxt，此行为是否正常？ .js？
