Question

我有一个使用json和ajax的程序。当我单击“确定”按钮时，它将在控制台中显示结果，而不是在控制台日志中显示一行，而是将其显示为我尝试使用编码功能尝试的每行显示行，但仍然无法正常工作。 / p>

兄弟姐妹应该显示在首页的控制台上这是我的代码

  <script type="text/javascript">

kyu = (function (document, window, kyu) {   
  var node = Node.prototype,
      nodeList = NodeList.prototype,
      forEach = 'forEach',
      trigger = 'trigger',
      each = [][forEach], 
      dummy = document.createElement('i');

  nodeList[forEach] = each;

  window.on = node.on = function (event, fn) {
    this.addEventListener(event, fn, false);

    return this;
  };

  nodeList.on = function (event, fn) {
    this[forEach](function (el) {
      el.on(event, fn);
    });
    return this;
  };

  window[trigger] = node[trigger] = function (type, data) { 
    var event = document.createEvent('HTMLEvents');
    event.initEvent(type, true, true);
    event.data = data || {};
    event.eventName = type;
    event.target = this;
    this.dispatchEvent(event);
    return this;
  };

  nodeList[trigger] = function (event) {

  kyu = function (s) { 
    var r = document.querySelectorAll(s || '?'),
        length = r.length;

  kyu.on = node.on.bind(dummy);
  kyu[trigger] = node[trigger].bind(dummy);

  return kyu;

 <script type="text/javascript">

    var siblings= kyu('.siblings');
     var wew=0;
    var res="";
    var data="{";
    while(siblings.length>wew){
      data+= "'Siblings #" + (wew+1) +"': '"+siblings[wew].value+"', ";
      wew++; 
    }
 data+="}";  
 var po= data.slice(0,-3)+"}"
 //var data={po};
  req.onreadystatechange = function() {
  if(req.readyState == XMLHttpRequest.DONE){
    var wew = JSON.parse(req.responseText); 

      // var new1p= new array('Siblings'=>wew);
      var ll= wew.Siblings; 
        //alert(ll);
     console.log(ll);

      //var mop=(JSON.parse(wew.Siblings));
  }
};
req.open("POST", "poi2.php", true);
req.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
req.send('siblings='+po);
}
</script>

第二页是

<?php
extract($_POST);
$result= $siblings; 
$arrayName = array('Siblings'=>$result);

$poi = json_encode($arrayName);
echo $poi;
?>

Answer 1

ll是NodeList时，可以将其转换为数组，然后可以使用数组方法对其进行操作。

就像用换行符加入它一样：

Array.prototype.slice.call(ll).join('\r\n')
