一个支持ff的modaldialog的js代码

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 its 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 windows 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); 
        }
