我正在使用jQuery sortable。我希望能够获取移动项目的ID以及替换项目的ID。到目前为止,我能够获取移动元素的ID,但不能获取它所替换的元素。
我的代码是:
$(function () {
$("#sortable").sortable({
stop: function (event, ui) {
var moved = ui.item,
replaced = ui.item.prev();
// if replaced.length === 0 then the item has been pushed to the top of the list
// in this case we need the .next() sibling
if (replaced.length == 0) {
replaced = ui.item.next();
}
alert("moved ID:" + moved.attr("id"), "replaced ID:" + replaced.attr("id"));
}
});
});
如何取回要替换的元素的ID和移动的元素?
答案 0 :(得分:3)
实际上它有效,你只是用错误的参数调用警报;将其替换为console.log
或者将这些字符串连接起来:
alert("moved ID:" + moved.attr("id") + "replaced ID:" + replaced.attr("id"));
(我将,
替换为+
)
