拖拽核心代码:
复制代码 代码如下:
function drag(obj) {
if (typeof obj === 'string') {
var obj = document.getElementById(obj);
} else {
var obj = obj;
}
function fixEvent(event) {
event.target = event.srcElement;
event.preventDefault = fixEvent.preventDefault;
return event;
}
fixEvent.preventDefault = function () {
this.returnValue = false;
};
obj.onmousedown = mousedown;
function mousedown(e) {
var e = e || fixEvent(window.event);
var disX = e.clientX - obj.offsetLeft;
var disY = e.clientY - obj.offsetTop;
if (e.target.tagName === 'H2') {
document.onmousemove = move;
document.onmouseup = up;
} else {
document.onmousemove = null;
document.onmouseup = null;
}
function move(e) {
var e = e || fixEvent(window.event);
var left = e.clientX - disX;
var top = e.clientY - disY;
if (obj.setCapture) {
obj.setCapture();
}
if (left < 0) {
left = 0;
} else if (left > document.documentElement.clientWidth - obj.offsetWidth) {
left = document.documentElement.clientWidth - obj.offsetWidth;
}
if (top < 0) {
top = 0;
} else if (top > document.documentElement.clientHeight - obj.offsetHeight) {
top = document.documentElement.clientHeight - obj.offsetHeight;
}
obj.style.left = left + 'px';
obj.style.top = top + 'px';
return false;
};
function up() {
if (obj.releaseCapture) {
obj.releaseCapture();
}
document.onmousemove = null;
document.onmouseup = null;
}
};
}
调用代码:
复制代码 代码如下:
window.onload = function () {
var login = document.getElementById('login');
drag(login);
};

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
