uniGUI学习之脱离Delphi直接写ExtJS从入门到精通03自定义函数_调用顺序(47)

自定义函数fn

 

<link  rel="stylesheet"  href="theme-gray-all.css">
<script src="ext-all.js" ></script>

        <script type="text/javascript">
Ext.onReady(function(){

    var fn = function(e, el, args) {
        alert("handle1");
        alert(args.testId);
    };

    Ext.get('test').on('click', fn, this, {
        single: true,
        delay: 100,
        testId: 4
    });
});
        </script>

        <button id="test">测试</button>

调用顺序

<link  rel="stylesheet"  href="theme-gray-all.css">
<script src="ext-all.js" ></script>
    <script type="text/javascript">
Ext.onReady(function(){

    var EXTtest = Ext.get('test');

    EXTtest.on('click', function() {
        alert("handle1");
    });
    EXTtest.on('click', function() {
        alert("handle2");
    });

});
        </script> 
    
        <button id="test">显示</button>  

调用顺序

<button><script>先后顺序问题

 <button id="test">显示</button>

   <script type="text/javascript">
var e = document.getElementById("test");
e.onclick = function() {
    alert("handle1");
};
e.onclick = function() {
    alert("handle2");
};
 </script>

《button》《script》先后顺序问题。
