我正在使用jquerytreeview插件。有没有办法添加一个回调函数,在我加载数据后调用它?
$("#tree").treeview({
url: "/loadtree",
callback: my_function // this is what i wanted to do
});

异步树视图中没有回调,但添加自己的回调应该足够容易。AJAX的东西就在这里:
https://github.com/jzaefferer/jquery-treeview/blob/master/jquery.treeview.async.js#L42
$.ajax($.extend(true, {
url: settings.url,
dataType: "json",
data: {
root: root
},
success: function(response) {
child.empty();
$.each(response, createNode, [child]);
$(container).treeview({add: child});
}
}, settings.ajax));
您可以通过添加<code>settings.dataLoaded</code>并将上面的代码段更改为如下内容来添加回调:
$.ajax($.extend(true, {
url: settings.url,
dataType: "json",
data: {
root: root
},
success: function(response) {
if(settings.dataLoaded)
settings.dataLoaded();
child.empty();
$.each(response, createNode, [child]);
$(container).treeview({add: child});
}
}, settings.ajax));
我刚刚在success下面添加了两行:
。然后你可以这样设置树景:
$("#tree").treeview({
url: "/loadtree",
dataLoaded: my_function
});
我还没有尝试过,但它应该会起作用,如果没有,这将是一个很好的起点。
你可以访问源代码,没有充分的理由不使用它。而且,没有充分理由不自己添加回调支持,并向Jörn Zaeffer发送一个补丁,将此功能添加到主存储库中。
添加回调真的很有帮助-谢谢。
我发现您可能想要更改树视图异步源代码中的顺序。
$.ajax($.extend(true, {
url: settings.url,
dataType: "json",
data: {
root: root
},
success: function(response) {
child.empty();
$.each(response, createNode, [child]);
$(container).treeview({add: child});
if(settings.dataLoaded)
settings.dataLoaded();
}
}, settings.ajax));
通过这种方式,异步脚本可以完成对DOM的修改。现在请注意settings.dataLoaded位于sucess:function的末尾。
