manually trigger jquery keyup?
提问by Devil's Advocate
I think I figured it out... see my comment. Sorry.
我想我想通了……看我的评论。对不起。
I have a JSON web service that is called on a certain keyup() event which retrieves some data based on the input. I would like to load an initial set of data before anything is typed. I'm trying to manually invoke the keyup() as stated in the documentation, but it doesn't seem to do anything.
我有一个 JSON Web 服务，它在某个 keyup() 事件上调用，它根据输入检索一些数据。我想在输入任何内容之前加载一组初始数据。我正在尝试按照文档中的说明手动调用 keyup()，但它似乎没有做任何事情。
$('#inputItemName').keyup(function () {
//perform query, display results
});
^^ works great when you type in the box
^^ 在框中输入时效果很好
$('#inputItemName').keyup();
^^ called immediately after document ready function, doesn't seem to do anything.
^^ 在文档就绪函数之后立即调用，似乎没有做任何事情。

Works fine for me: http://jsfiddle.net/radu/gD5WL/
对我来说很好用：http: //jsfiddle.net/radu/gD5WL/
$('#test').keyup(function () {
console.log('hello');
});
$('#test').keyup();
The keyupevent is getting called on page load.
该keyup事件在页面加载时被调用。

$('#inputItemName').trigger('keyup');

You are missing a #in selector...
try with hash...
您缺少一个#in 选择器...尝试使用哈希...
$('#inputItemName').keyup();
$('#inputItemName').keyup();

I think I figured it out... I moved the function that calls the results higher up in the script tag than the keyup()invocation and now it works.
我想我想通了……我将在脚本标记中keyup()调用结果的函数移动到比调用更高的位置，现在它可以工作了。

You're missing the hash marker for the id in the second one:
您在第二个中缺少 id 的哈希标记：
$('#inputItemName').keyup();
$('#inputItemName').keyup();

尝试这个：
$('#inputItemName').bind('keyup',function() {
//stuff
});
