<script>
export default {
mounted() {
//获取dom
var drapLine = document.getElementById('drap-line');
var left = document.getElementById('left');
var right = document.getElementById('right');
//设置最大/最小宽度
var max_width = 600,
min_width = 100;
//记录鼠标相对left盒子x轴位置
var mouse_x = 0;
var history_width = localStorage.getItem('sliderWidth');
if (history_width) {
left.style.width = history_width;
right.style.left = history_width;
}
//绑定鼠标按下事件
drapLine.onmousedown = function (e) {
var e = e || window.event;
//阻止默认事件
e.preventDefault();
mouse_x = e.clientX - left.offsetWidth;
document.onmousemove = function (e) {
var e = e || window.event;
var left_width = e.clientX - mouse_x;
left_width = left_width < min_width ? min_width : left_width;
left_width = left_width > max_width ? max_width : left_width;
left.style.width = left_width + 'px';
right.style.left = left_width + 'px';
};
document.onmouseup = function (e) {
document.onmousemove = null;
document.onmouseup = null;
//localStorage设置
localStorage.setItem('sliderWidth', left.style.width)
};
}
},
methods: {
