防止在HTML中进行选择

function makeUnselectable(node) {
    if (node.nodeType == 1) {
        node.setAttribute("unselectable", "on");
    }
    var child = node.firstChild;
    while (child) {
        makeUnselectable(child);
        child = child.nextSibling;
    }
}

makeUnselectable(document.getElementById("foo"));

似乎CSS用户选择不会阻止图像拖放...所以..

HTML:

 Blabla bla blabla

CSS:

* {
     user-select: none;
    -khtml-user-select: none;
    -o-user-select: none;
    -moz-user-select: -moz-none;
    -webkit-user-select: none;
}

::selection { background: transparent;color:inherit; }
::-moz-selection { background: transparent;color:inherit; }

JS:

$(function(){
    $('*:[unselectable=on]').mousedown(function(event) {
        event.preventDefault();
        return false;
    });
});

我使用cancelBubble=true并stopPropagation()在鼠标中向下移动处理程序.
