for example, the assignment is as follows:
var div = self.$refs["dialog-wrap"].$refs["wrap"];
this.$nextTick(() => {
div.scrollTop = div.scrollHeight
console.log("scrollHeight", div.scrollHeight)
console.log("scrollTop", div.scrollTop)
})
console.log comes out like this, the assignment is invalid, and the dialog box scrolls, but not completely to the bottom:
if you send a long picture, have you considered whether the picture has been loaded? if not, the calculated scrollHeight may not be correct.
instead of directly assigning values to scrollTop , scroll window.scrollTo (x coordinates, Y coordinates)
window.scrollTo(0, div.scrollHeight)it should be as said downstairs that the height was calculated before your picture was loaded, which was caused by incorrect height calculation. You add an onload event to the image, and then re-call the method that moves to the bottom after loading.
