在 jQuery 中附加回调
原标题:Append callback in jQuery

我有一个解决办法:

var addContent = {
...
append: function (obj, data, callBack) {
        "use strict";
        obj.append(data);
        callBack();
    }
}

The "addContent.append()" function add its data parameter value to its obj and call its callBack(), it is working as well! But the "obj parameter" hasn t been in DOM then those element what found it in "data parameter" not available.

例如:

var to = jQuery( <div> );
addContent.append(to,  <div id="element1"></div> , function () {
    alert(jQuery( #element1 ).length);
});

代码上写着"0"

你有什么解决办法吗?

谢谢!

最佳回答

如果我正确理解了您的问题,问题在于 to 所提到的元素不在 DOM 中,所以当您试图选择附在其中的元素时,找不到这些元素(因为他们的父母不在 DOM 中)。

我认为你可能想要的 是上下文的论据:

alert(jQuery( #element1 , to).length);

这将选择匹配

使用文件备就功能

jQuery(document).ready(function(){
    var addContent = {
    append: function (obj, data, callBack) {
            "use strict";
            obj.append(data);
            callBack();
        }
    }
    var to = jQuery( div );
    addContent.append(to,  <div id="element1">545</div> , function () {
        alert(jQuery( #element1 ).length);
    });
});
