我尝试通过 this.get_element() 访问我自己的函数中的元素，但它不起作用。
Type.registerNamespace("LabelTimeExtender1");
LabelTimeExtender1.ClientBehavior1 = function(element) {
LabelTimeExtender1.ClientBehavior1.initializeBase(this, [element]);
var testelement=this.get_element();
var timestamp= this.get_element().attributes['TimeStamp'].value;
alert("in constructor");
},
LabelTimeExtender1.ClientBehavior1.prototype = {
initialize: function() {
LabelTimeExtender1.ClientBehavior1.callBaseMethod(this, 'initialize');
setInterval (this.timer,1000);
alert("after");
},
dispose: function() {
//Add custom dispose actions here
LabelTimeExtender1.ClientBehavior1.callBaseMethod(this, 'dispose');
},
timer: function(){
debugger;
var date= new Date(this.timestamp);
var datenow= new Date ();
this._element.innerText=" ";
if(date.getUTCFullYear<datenow.getUTCFullYear)
{
var myelement= this.get_element();
myelement .innerHTML= date.getUTCFullYear.toString();
}
if(date.getUTCMonth<datenow.getUTCMonth)
{
this.get_element().innerHTML=date.getUTCMonth.toString();
}
if(date.getUTCDay<datenow.getUTCDay)
{
this.get_element().innerHTML=date.getUTCDay.toString();
}
if(date.getUTCHours <datenow.getUTCHours )
{
this.get_element().innerHTML=date.getUTCHours .toString();
}
if(date.getUTCMinutes<datenow.getUTCMinutes)
{
this.get_element().innerHTML=date.getUTCMinutes.toString();
}
}
}
LabelTimeExtender1.ClientBehavior1.registerClass('LabelTimeExtender1.ClientBehavior1', Sys.UI.Behavior);
if (typeof(Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();
在这里，我试图访问自定义属性“TimeStamp”并计算时间并分配给要显示的标签。
