键盘事件中keyCode、which和charCode 的兼容性测试 [js+css]点击隐藏层,点击另外层不能隐藏原层

这是我看到的另一种方法了，虽然仍然不怎么样，不过了解一下也是不错的，目前代码不支持opera，我也没时间看能否支持＝。＝

点击运行可以看到效果:<script> // Though "Dialog" looks like an object, it isn't really an object. Instead // it's just namespace for protecting global symbols. function Dialog(url, action, init) { if (typeof init == "undefined") { init = window; // pass this window object by default } if (document.all) { // here we hope that Mozilla will never support document.all var value = showModalDialog(url, init, // window.open(url, '_blank', // "resizable: no; help: no; status: no; scroll: no"); "resizable: yes; help: no; status: no; scroll: no"); if (action) { action(value); } } else { return Dialog._geckoOpenModal(url, action, init); } }; Dialog._parentEvent = function(ev) { if (Dialog._modal && !Dialog._modal.closed) { Dialog._modal.focus(); // we get here in Mozilla only, anyway, so we can safely use // the DOM version. ev.preventDefault(); ev.stopPropagation(); } }; // should be a function, the return handler of the currently opened dialog. Dialog._return = null; // constant, the currently opened dialog Dialog._modal = null; // the dialog will read it's args from this variable Dialog._arguments = null; Dialog._geckoOpenModal = function(url, action, init) { var dlg = window.open(url, "ha_dialog", "toolbar=no,menubar=no,personalbar=no,width=10,height=10," + "scrollbars=no,resizable=no"); Dialog._modal = dlg; Dialog._arguments = init; // capture some window's events function capwin(w) { w.addEventListener("click", Dialog._parentEvent, true); w.addEventListener("mousedown", Dialog._parentEvent, true); w.addEventListener("focus", Dialog._parentEvent, true); }; // release the captured events function relwin(w) { w.removeEventListener("focus", Dialog._parentEvent, true); w.removeEventListener("mousedown", Dialog._parentEvent, true); w.removeEventListener("click", Dialog._parentEvent, true); }; capwin(window); // capture other frames for (var i = 0; i < window.frames.length; capwin(window.frames[i++])); // make up a function to be called when the Dialog ends. Dialog._return = function (val) { if (val && action) { action(val); } relwin(window); // capture other frames for (var i = 0; i < window.frames.length; relwin(window.frames[i++])); Dialog._modal = null; }; }; Dialog("http://google.com",function(){alert('test')},null); </script>
