首先，获取浏览器的宽度和高度是关键。通过检测window对象的`innerWidth`属性，或者在`document.documentElement.clientWidth`和`document.body.clientWidth`中取非null值，我们可以得到浏览器的可视区域宽度`w`。同样地，使用`window.innerHeight`、`document.documentElement.clientHeight`或`document.body.clientHe...
根据键盘的高度是否大于0来判断键盘是否已经显示或隐藏,并根据实际需求来决定是否将页面上移。 methods:{handleResize(){constwindowHeight=window.innerHeight;constkeyboardHeight=windowHeight-document.documentElement.clientHeight;if(keyboardHeight>0){this.isKeyboardVisible=true;}else{this.isKeyboardVisible=false;}}},...

也就是说元素的右侧超出屏幕的右侧,就让元素的右侧在屏幕的右侧上l = document.documentElement.clientWidth -oDiv.offsetWidth; }if(t < 0) {//和左右距离同理t = 0; }elseif(t > document.documentElement.clientHeight -oDiv.offsetHeight) { t= document.documentElement.clientHeight -oDiv.offsetHeight; }/...
