如果需要随意移动弹窗,可以在<script></script>中加入以下代码:
window.onload = function (){var myDiv = document.getElementById("MyDiv");var move = document.getElementById("move");var bDrag = false;var disX = disY = 0;move.onmousedown = function (event){var event = event || window.event;bDrag = true;disX = event.clientX - myDiv.offsetLeft;disY = event.clientY - myDiv.offsetTop;this.setCapture && this.setCapture();return false;};document.onmousemove = function (event){if (!bDrag) return;var event = event || window.event;var iL = event.clientX - disX;var iT = event.clientY - disY;var maxL = document.documentElement.clientWidth - myDiv.offsetWidth;var maxT = document.documentElement.clientHeight - myDiv.offsetHeight;iL = iL < 0 ? 0 : iL;iL = iL > maxL ? maxL : iL;iT = iT < 0 ? 0 : iT;iT = iT > maxT ? maxT : iT;myDiv.style.marginTop = myDiv.style.marginLeft = 0;myDiv.style.left = iL + "px";myDiv.style.top = iT + "px";return false;};document.onmouseup = window.onblur = move.onlosecapture = function (){bDrag = false;move.releaseCapture && move.releaseCapture();};}
