雅虎 UI 自定义按钮

发布于 2024-08-16 07:06:10 字数 966 浏览 5 评论 0原文

我有一个通过 HTML 标记定义的 YUI 按钮。我设法正确地加载和“蒙皮”。

问题是自定义点击事件。我尝试了多种方法，所有这些方法都将自定义函数链接到“单击”事件，但无论我采用哪种方式，它总是在页面加载时触发，然后单击时不会触发。我似乎无法让它“等待”用户点击。在他第一次约会时，它就像处女一样。

代码如下....

<script type="text/javascript">
    YAHOO.util.Event.onContentReady("submitbutton", onButtonReadySubmit);
    YAHOO.util.Event.onContentReady("editbutton",onButtonReadyEdit);

    var myTabs = new YAHOO.widget.TabView("demo");
    function editDoc(sBaseRef, sUNID) {
        var sNewURL = sBaseRef + "/0/" + sUNID + "?EditDocument";
        alert("Going to : " + sNewURL);
     window.location.href=sNewURL;
    }
    function onButtonReadySubmit() {
 var oSubmitButton = new YAHOO.widget.Button("submitbutton");
    }
    function onButtonReadyEdit() {
        var oEditButton = new YAHOO.widget.Button("editbutton");
        YAHOO.util.Event.addListener("editbutton", 'click', editDoc('a URL path goes here' , 'A PageKey goes here'));
    }

I have a YUI button defined through HTML markup. I managed to get it loaded and "skinned" properly.

The problem is a custom click event. I have tried a number of approaches all of which links the custom function to the 'click' event, but no matter which way I do it, it ALWAYS triggers upon page loading and then it doesn't fire when clicked. I can't seem to get it to "wait" for a user to click. It just shoots like a virgin on his first date.

Code below....

<script type="text/javascript">
    YAHOO.util.Event.onContentReady("submitbutton", onButtonReadySubmit);
    YAHOO.util.Event.onContentReady("editbutton",onButtonReadyEdit);

    var myTabs = new YAHOO.widget.TabView("demo");
    function editDoc(sBaseRef, sUNID) {
        var sNewURL = sBaseRef + "/0/" + sUNID + "?EditDocument";
        alert("Going to : " + sNewURL);
     window.location.href=sNewURL;
    }
    function onButtonReadySubmit() {
 var oSubmitButton = new YAHOO.widget.Button("submitbutton");
    }
    function onButtonReadyEdit() {
        var oEditButton = new YAHOO.widget.Button("editbutton");
        YAHOO.util.Event.addListener("editbutton", 'click', editDoc('a URL path goes here' , 'A PageKey goes here'));
    }

YUI Button 发布您在 YUI Button 实例上订阅的自己的单击事件，而不是使用 YAHOO.util.Event.addListener。 YUI Button 登陆页面对此进行了详细描述： http://developer.yahoo.com /yui/button/#handlingevents。

你的问题是第三个参数。那应该是对函数的引用。您的代码中发生的情况是，第 3 个参数是一个函数，在创建侦听器时调用该函数，并且不返回任何内容。

您拥有：

YAHOO.util.Event.addListener("editbutton", 'click', editDoc(
    'a URL path goes here', 
    'A PageKey goes here'
));

您想要的只是：

YAHOO.util.Event.addListener("editbutton", 'click', editDoc);

但是，您还希望将“此处为 URL 路径”和“此处为 PageKey”传递给点击时的函数 -时间。为此，请使用 addListener() 的可选第四个参数 - 要传递给函数的对象。

function editDoc (ev, oArgs) {
   var sBaseRef = oArgs.url,
       sUNID    = oArgs.key;

   /* code here */

}

YAHOO.util.Event.addListener("editbutton", 'click', editDoc, { 
    url: 'a URL path goes here',
    key: 'A PageKey goes here'
});

请参阅 http://developer.yahoo.com/yui/docs /YAHOO.util.Event.html#method_addListener 了解更多。

正如 Todd 提到的，您也可以将其作为 YUI 按钮创建的一部分来执行 - 但同样存在函数与函数引用的问题。

Your problem is the 3rd argument. That should be a reference to function. What happens in your code is that the 3 argument is a function that is called as the listener is being created, and returns nothing.

You have:

YAHOO.util.Event.addListener("editbutton", 'click', editDoc(
    'a URL path goes here', 
    'A PageKey goes here'
));

Simply what you want is:

YAHOO.util.Event.addListener("editbutton", 'click', editDoc);

However, you also want to pass 'a URL path goes here' and 'A PageKey goes here' to the function at click-time. To do this, use the optional fourth argument to addListener() - an object to pass to the function.

function editDoc (ev, oArgs) {
   var sBaseRef = oArgs.url,
       sUNID    = oArgs.key;

   /* code here */

}

YAHOO.util.Event.addListener("editbutton", 'click', editDoc, { 
    url: 'a URL path goes here',
    key: 'A PageKey goes here'
});

See http://developer.yahoo.com/yui/docs/YAHOO.util.Event.html#method_addListener for more.

As Todd mentions, you can also do this as part of the YUI Button creation - but the same issues of function versus function references apply.
