如果你的目标不是Opera9或更低版本，IE9或更低版本，你可以使用css属性 pointer-events: none 。

我发现忽略iframe是最好的方法。我在 onMouseDown 事件中向iframe添加了具有此属性的类，并在 onMouseUp 事件中将其删除。

对我来说太完美了。

Iframes捕获鼠标事件，但如果满足跨域策略，则可以将事件传输到父范围。下面是操作步骤：

// This example assumes execution from the parent of the the iframe
function bubbleIframeMouseMove(iframe){
    // Save any previous onmousemove handler
    var existingOnMouseMove = iframe.contentWindow.onmousemove;
    // Attach a new onmousemove listener
    iframe.contentWindow.onmousemove = function(e){
        // Fire any existing onmousemove listener 
        if(existingOnMouseMove) existingOnMouseMove(e);
        // Create a new event for the this window
        var evt = document.createEvent("MouseEvents");
        // We'll need this to offset the mouse move appropriately
        var boundingClientRect = iframe.getBoundingClientRect();
        // Initialize the event, copying exiting event values
        // for the most part
        evt.initMouseEvent( 
            "mousemove", 
            true, // bubbles
            false, // not cancelable 
            window,
            e.detail,
            e.screenX,
            e.screenY, 
            e.clientX + boundingClientRect.left, 
            e.clientY + boundingClientRect.top, 
            e.ctrlKey, 
            e.altKey,
            e.shiftKey, 
            e.metaKey,
            e.button, 
            null // no related element
        // Dispatch the mousemove event on the iframe element
        iframe.dispatchEvent(evt);
