Copy code
Custom instruction function :
Vue.directive('barDrag', {
bind (el, binding, vnode, oldVnode) {
Vue.nextTick(() => { // no need nextTick No other dom node
// Set whether to move the id
let removeFlag = false
// Get the left scaled div object
let bar = el
let dragLeft = el.previousElementSibling.style
let dragRight = el.nextElementSibling.style
let doc = el.parentNode
let x = 0 // Mouse X and Y Axis coordinates
// Mount mouse event
bar.addEventListener('mousedown', moveDownMouse, false)
// Note that the movement and mouse out of focus events need to be bound to dom On , If only bound to bar Only in bar Move up \ Out of focus is effective
doc.addEventListener('mousemove', mouseMove, false)
doc.addEventListener('mouseup', mouseUp, false)
function moveDownMouse (e) {
removeFlag = true
// After pressing the element Calculate the coordinates of the current mouse and object after calculation
x = e.clientX - bar.offsetWidth - dragLeft.width.replace('px', '')
// Support setCapture when Capture focus // Set up events // The binding event
if (bar.setCapture) {
bar.setCapture()
bar.onmousemove = function (ev) {
mouseMove(ev || event)
}
bar.onmouseup = mouseUp
} else {
// bar.addEventListener('mousemove', mouseMove, false)
// bar.addEventListener('mouseup', mouseUp, false)
// jQuery(document).bind('mousemove', mouseMove).bind('mouseup', mouseUp)
}
// Prevent default events from happening
e.preventDefault()
store.state.dragBar = false // Used to inform echarts When the width changes, reload
}
// Mobile event
function mouseMove (e) {
if (removeFlag) {
// In the super invincible operation of the universe
let width = e.clientX - x
if (width < 200) {
dragLeft.width = '200px'
} else if (width > 400) {
dragLeft.width = '400px'
} else {
dragLeft.width = width + 'px'
}
// If the right width is not calculated , The drag bar will be squeezed Subtract the width of the drag bar. Note the style .dragBar The settings are consistent
dragRight.width = 'calc((100% - 3px) - ' + dragLeft.width + ')'
}
}
// Stop the event
function mouseUp () {
removeFlag = false
// Support releaseCapture when // Release focus // Remove events // Uninstall Events
if (bar.releaseCapture) {
bar.releaseCapture()
bar.onmousemove = bar.onmouseup = null
