JavaScript function is only working the first time I call it? -


I was wondering if you can help me troubleshoot problems. Hopefully you will not need a document to use the graphics package to identify this problem, but if this happens, go here.

I have the following block of code 

  window.setInterval (function () {mycirc.transform ("t1,1");}, 500);   
 Definitely call the function  mycirc.transform ("t1,1")  every half-second that function will be  mycirc  Each unit should translate the x and y coordinate (see Element.transform (see [tstr]).  
 However, when I check my page,  mycirc  is translated once and there is no effect of the call after it. I've used  console.log (...)  to test and make sure:  
  window.setInterval (function () {var bb = mycirc .getBBox (); console log ("before conversion:" + bb.x + "," + bb.y "); mycirc.transform (" t1,1 "); var bb = mycirc.getBBox (); console.log ("After coord conversion:" + bb.x + "," + bb.y);}, 500); Courses before change: 120.98508107696858,106 jsfunctions.js: 411 cord after transformation: 121.98508107696858, 107 jsfunctions.js: 414 courses before conversion:   
 yields  121.98508107696858,107 jsfunctions.js: 411 cord after transformation: 121.98508107696858 , 107 jsfunctions.js: 411   
 etc.  
 Why can any idea?  
 (I used the source code for the graphics package , But it is ineligible due to some white space.)   
 
 
 Your code < / p> 
  mycirc.transform ("t1,1");   
 is not related to the current state. It just changes from the original state to  t1,1  and then from  t1,1  to  t1,1  etc.  
 You should calculate the change every time.  
  Edit : So it will need a global variable, every time increments like this:  
  var xyPos = 1; window.setInterval (function () {mycirc.transform ("t" + xyPos + "," + xyPos); xyPos ++;}, 500);
