Question

下面我呼吁本机构发挥职能,而我想的是,当我在案文箱中发表任何内容时,它将提醒我注意文本箱的名称,我想查看姓名,然后执行一些内容。核对名称在FF而不是IE工作。增编

<body bgcolor="#F2F2F2" OnKeyPress="return getFieldName(event);">

......

function getFieldName(e) {
    e = e || window.event;
    var key = e.keyCode || e.which,
    target = e.target || e.srcElement;
}

This works but target.name is not trappable in IE for eg:

if (target.name ==  one ) {
    //we can reach here is FF and Not in IE
}

Answer 1

你们可以知道,通过研究<代码>e.target的不动产(或e.srcElement for IE):

function getFieldName(e) {
  e = e || window.event;
  var key = e.keyCode || e.which,
      target = e.target || e.srcElement;

  alert(target.name);
  return (key != 13);
}

参见。
