停止拉伸功能
function stopstretching(watch) {
watcherObj = null;
removeEvent(document.getElementById("dragWorkspace"), 'mouseup', stopstretching);
removeEvent(document.getElementById("dragWorkspace"), 'mouseout', stopstretching);
removeEvent(document.getElementById("dragWorkspace"), 'mousemove', continuestretching);
var objToRemove = document.getElementById("dragWorkspace");
if (document.all) {
var oldLayer = objToRemove.removeNode(true);
} else {
var oldLayer = objToRemove.parentNode.removeChild(objToRemove);
}
}
在Chrome和Firefox中一切都很好用,但在IE中,stopstretch事件没有触发,我必须再次点击才能实际停止拉伸元素:(。请帮我解决。在鼠标输出时它应该停止拉伸。

删除活动时,您需要传递用于添加活动的相同功能。
当您添加使用的事件处理程序时:function() { stopstretching(watcherObj); }
mouseup
和function() { stopstretching(watcherObj); }
mouseout
(这两个不同)
因此,当您删除时,您不能只使用stopstretching
,因为它不是您添加的那个。也许你可以拥有像
function stopHandler() {
stopstretching(watcherObj, stopHandler);
}
addEvent(dragWorkspaceObj, 'mouseup', stopHandler);
addEvent(dragWorkspaceObj, 'mouseout', stopHandler);
和
function stopstretching(watch, handler) {
watcherObj = null;
removeEvent(document.getElementById("dragWorkspace"), 'mouseup', handler);
removeEvent(document.getElementById("dragWorkspace"), 'mouseout', handler);
代码未经测试,但我认为它应该有用。
