var movebox; window.onload = function () { movebox = document.getElementById("movebox"); movebox.addEventListener("mousedown", function (e) { if (e.button > 0) { fun2(); return false; } e.preventDefault && e.preventDefault(); //明哥：去掉图片拖动响应 狠重要 gen.x = e.clientX; gen.y = e.clientY; gen._x = movebox.offsetLeft; gen._y = movebox.offsetTop; gen.dx = gen.x - gen._x; gen.dy = gen.y - gen._y; document.addEventListener("mousemove",fun1,false); document.addEventListener("mouseup", fun2, false); }, false); }; var fun1 = function (e) { gen.L = e.clientX - gen.dx; gen.T = e.clientY - gen.dy; var timefun = function () { window.getSelection().removeAllRanges(); if (gen.L < 100) gen.L = 100; else if (gen.L > 200) gen.L = 200; if (gen.T < 125) gen.T = 125; else if (gen.T > 175) gen.T = 175; setLT(movebox, gen.L, gen.T); }; setTimeout(timefun, 2); }; var fun2 = function () { document.removeEventListener("mousemove", fun1, false); document.removeEventListener("mouseuo", fun2, false); }; var gen = { x: null, y: null, _x: null, _y: null, dx: null, dy: null, L: null, T:null, }; var setLT = function (dom, L, T) { dom.style.left = L + "px"; dom.style.top = T + "px"; }; css:
