Ajax响应处理

Question

I use this lines to processing responseText from Ajax call.

response=JSON.parse(xmlhttp.responseText)
    len=response.length;
    console.log(len);
    for(i=0;i<len; i++){
        console.log(i);
        alert(response[i].IPO)
        //COCView.lb01Select.appendChild(new DOMtag('option'{'id':response[i].CO_HDR_ID,'innerHTML':response[i].ONR}));
    }
}

After i want to use the inside function(appendChild), I can fetch only the first object of the response array! Could help me somebody, why stops the cycle?

Answer 1

I would try putting all of that inside an anonymous function and see if that helps, such as:

JSON.parse(xmlhttp.responseText, function(response){ 
  len=response.length;
  console.log(len);
  for(i=0;i<len; i++){
    console.log(i);
    alert(response[i].IPO)
    //COCView.lb01Select.appendChild(new DOMtag('option'{'id':response[i].CO_HDR_ID,'innerHTML':response[i].ONR}));
  }
});

Also, dump what you are getting for "response" and see if that is what you expect.
