Problem using setTimeout in classes! _javascript skills

What I do now, but I don’t want to write it like this:

[Ctrl A Select all Note: If you need to introduce external Js, you need to refresh it to execute

]
I hope to be able to do it when creating a calendar. There is no need to pass calendar1 in. In the setTimeout parameter, it can be executed directly through this.thread_result()

[Ctrl A Select all Note:

If you need to introduce external Js, you need to refresh to execute it
]

Senior Huanyu is not here. I will go first. Come and show me some clumsiness:)

The difficulty of this problem is Let this in the function point to the correct point Yes, winter’s method is good. The only problem is that there is a problem with the this pointer in the function. I have found a solution. I added the prototype function bindNode to the Function object for binding. It works. Let this point to any object <button id="btTest"> </button> Run

[Ctrl A Select all Note: <script> function calendar(name){ this._name = name; } calendar.prototype.thread=function(){ this._timeout = setTimeout(this._name + ".thread_result()", 200); } calendar.prototype.thread_result=function(){ alert("执行成功!"); } var calendar1; onload=function(){ calendar1 = new calendar("calendar1"); calendar1.thread(); } </script>If you need to introduce external Js, you need to refresh to execute <script> function calendar(){ } calendar.prototype.thread=function(){ this._timeout = setTimeout("this.thread_result()", 200); } calendar.prototype.thread_result=function(){ alert("执行成功!"); } onload=function(){ var calendar1 = new calendar(); calendar1.thread(); } </script>]<script> function calendar(){ this.str="执行成功"; } calendar.prototype.thread=function(){ var temp=this; this._timeout = setTimeout(function(){temp.thread_result()}, 200); } calendar.prototype.thread_result=function(){ alert(this.str); } onload=function(){ var calendar1 = new calendar(); calendar1.thread(); } </script><script> Function.prototype.bindNode=function(oNode){ var foo=this,iNodeItem if(window.__bindNodes==null) __bindNodes=[] __bindNodes.push(oNode) iNodeItem=__bindNodes.length-1 oNode=null return function(e){ foo.call(__bindNodes[iNodeItem],e||event) } } btTest.onclick=function(){ alert(this.tagName==null?"tagName="+this.tagName+"(普通情况下，this指向当前函数)":"tagName="+this.tagName+"(经过bindNode处理后，this可以指向任意传过来的对象)") } window.setTimeout(btTest.onclick,100) window.setTimeout(btTest.onclick.bindNode(btTest),200) </script>Questions about binding events My approach is to write a function array myself I feel that this is more original. Please give me some advice ^^
