jquery li元素id
我正在使用 jquery contextmenu 插件来右键单击菜单，我试图将其添加到带有 ID 邮箱的无序列表的每个 li 元素中。我的代码是：
$("#mailbox > li").contextMenu('myMenu1', {
bindings: {
'open': function(t) {
alert('Trigger was '+t.id+'\nAction was Open');
}
//CODE SNIPPED
});
我的假设是，这应该提醒调用 contextMenu 的列表元素的 id，但它返回一个空字符串。我是否正确访问/分配了这些？
顺便说一句，t 是上面上下文中的 HTMLLIElement 对象。
干杯， 加兹勒。
I am using a jquery contextmenu plugin for right click menus which I am trying to add to each li element of an unordered list with the ID mailbox. The code I have is:
$("#mailbox > li").contextMenu('myMenu1', {
bindings: {
'open': function(t) {
alert('Trigger was '+t.id+'\nAction was Open');
}
//CODE SNIPPED
});
My assumption is that this should alert the id of the list element that the contextMenu was called from, however it is returning an empty string. Am I accessing/assigning these correctly?
t is an object HTMLLIElement in the context above by the way.
Cheers,
Gazler.

尝试使用
"#mailbox li"作为选择器。原因是#mailbox没有任何lielement > 的子元素。 subelement仅适用于该元素的直接子元素。在这种情况下，#mailbox 的直接子代可能是 ul，而不是孙代的 li。element subelement选择所有后代，而不仅仅是直接子元素。在这里查看：http://docs.jquery.com/Selectors/child#parentchild

try using
"#mailbox li"as your selector. the reason is that#mailboxdoesn't have any children oflielement > subelementis for direct children of the element only. in this case, the direct child of#mailboxwould probably beuland notliwhich would be a grand child.element subelementselects all descendants, not just the direct children.check it out here: http://docs.jquery.com/Selectors/child#parentchild
